Answer:

6.21

Step-by-step explanation:

tha ratio 2.97/2.2 has to be the same as x/4.6.

so the new lenght, x, is 4.6×(2.97/2.2)

[tex]\stackrel{ \textit{ratio of (L)ength to (w)idth of old phone} }{\stackrel{L}{2.2}~~ : ~~\stackrel{w}{4.6}\qquad \implies \qquad \cfrac{L}{w}~~ = ~~\cfrac{2.2}{4.6}} \\\\\\ \stackrel{\textit{Length of new phone}}{2.97}\qquad \stackrel{\textit{keeping the same ratio}}{\cfrac{2.97}{w}~~ = ~~\cfrac{2.2}{4.6}} \\\\\\ (2.97)(4.6)=2.2w\implies \cfrac{(2.97)(4.6)}{2.2}=w\implies \stackrel{ new~width }{6.21=w}[/tex]

Part A: You can decompose Figure ABCDE into two triangles and two rectangles. The two triangles are triangle ABC and triangle AED. The two rectangles are rectangle BCD and rectangle AEB.

Part B: The length of Side AB is 4 units and the length of Side AE is 5 units.

Part C: To find the area of Figure ABCDE, we can simply add the areas of the two triangles and two rectangles. The area of triangle ABC is 3 units2, the area of triangle AED is 6 units2, the area of rectangle BCD is 10 units2, and the area of rectangle AEB is 3 units2. Thus, the area of Figure ABCDE is 3 + 6 + 10 + 3 = 22 units2.

When a fraction is equivalent to a percentage greater than 100, it means that the numerator represents a value that is greater than the denominator.

A percentage is a way to express a number as a fraction of 100. For example, 50% is the same as 50/100, which simplifies to 1/2.

Suppose we have a fraction that is equivalent to a percentage greater than 100, such as 125%. This means that the fraction represents 125 parts out of 100, or 125/100.

To simplify this fraction, we can divide both the numerator and denominator by the greatest common factor(GCF), which is 25 in this case. This gives us:

125/100 = (125 ÷ 25)/(100 ÷ 25) = 5/4

As we can see, the numerator (5) is greater than the denominator (4). This is because the original percentage value (125%) is greater than 100%, which means the fraction must have a numerator that is greater than the denominator to reflect this increase.

In general, if a fraction is equivalent to a percentage greater than 100, its numerator will be greater than its denominator because the percentage value represents a quantity that is greater than the whole (100%).

To find the distance from point P to the curved edge of the door mat, we can use the formula for an ellipse: (x/a)^2 + (y/b)^2 = 1, where a is the semi-major axis (half the length of the flat edge) and b is the semi-minor axis (half the length of the curved edge).

In this case, a = 148/2 = 74 cm and b = 58 cm. The point P is located 30 cm from the center, so x = 30 cm. We can plug these values into the formula and solve for y:

(30/74)^2 + (y/58)^2 = 1

0.1649 + (y/58)^2 = 1

(y/58)^2 = 0.8351

y^2 = 2805.72

y = sqrt(2805.72)

y = 52.97 cm

Therefore, the distance from point P to the curved edge of the door mat is approximately 52.97 cm.

Answer: 6x = 6x. || x is equal to any number.

Step-by-step explanation:

Step 1. 3x + 3 / 9 = 2x + 2 / 6

Step 2. We multiply all terms by the same value to eliminate fraction denominators, then cancel multiplied terms that are in the denominator. After this, distribute. 6x + 6 = 6x + 6

Step 3. Subtract 6 from both sides. 6x (6 - 6) = 6x (6 - 6)

Step 4. Simplify the expression. 6x = 6x

Step 5. x = any number.

Answer:

x is (a) 125.

Step-by-step explanation:

We can solve this proportion by using the property that the ratios of two equal proportions are equal. In other words:

a : b :: c : d if and only if a/b = c/d

Using this property, we can set up the proportion:

26 : 48 :: 82 : x

where x is the unknown term we want to find.

To solve for x, we can cross-multiply the terms in the proportion:

26 * x = 48 * 82

Simplifying the right side of the equation:

26 * x = 3936

Dividing both sides of the equation by 26:

x = 3936/26

x = 152

Therefore, the value of x is 152. However, 152 is not one of the answer choices provided. To choose the closest answer choice, we can round 152 to the nearest value among the answer choices. Rounding 152 to the nearest value, we get:

125: 27 less than 152

122: 30 less than 152

115: 37 less than 152

120: 32 less than 152

The closest value to 152 is 150, which is between 122 and 125. Therefore, the answer closest to the value of x is (a) 125.

Answer:

he probability of Violeta pulling out a green marble is 0.3 or 30%.

Step-by-step explanation:

he probability of pulling out a green marble is the number of green marbles divided by the total number of marbles in the bag:

P(green marble) = number of green marbles / total number of marbles

In this case, there are 6 green marbles and 14 pink marbles, so the total number of marbles is:

total number of marbles = 6 + 14 = 20

Therefore, the probability of pulling out a green marble is:

P(green marble) = 6 / 20 = 3/10 = 0.3

So the probability of Violeta pulling out a green marble is 0.3 or 30%.

Answer:

57%

Step-by-step explanation:

Let's consider the total number of students as 100%.

60% of all students are senior, which means that the rest (40%) are juniors.

Out of all senior students, 45% have school meals.

To find the percentage of senior students who have school meals, we should do the following:

[tex]\ \frac{45\% \times60\%}{100\%} = 27\%[/tex]

This is the percentage of students who are senior and have school meals.

We need to repeat the same procedure with junior students.

To do that, we need to find the 75% of 40% out of total, which is 100%.

[tex] \frac{75\% \times 40\% }{100\%} = 30\%[/tex]

This is the percentage of junior students who have school meals.

Finally we need to add up the percentages to find the total percentage of students who have school meals.

[tex]27\% + 30\% = 57\%[/tex]

The monthly cost for 39 minutes of calls is $15.34.

We can use the two given data points to form two equations and then solve for the unknown coefficients of the linear function.

Let the monthly cost (in dollars) be denoted by C, and let the total calling time (in minutes) be denoted by T. Then we can write:

C = aT + b

where a is the slope of the line (representing the rate of change of cost per minute of calling time), and b is the y-intercept of the line (representing the fixed monthly cost).

Using the given data points (34, 14.69) and (57, 17.68), we can form the following two equations:

14.69 = 34a + b (equation 1)

17.68 = 57a + b (equation 2)

Subtracting equation 1 from equation 2, we get:

17.68 - 14.69 = 57a - 34a + b - b

2.99 = 23a

a = 2.99/23

a = 0.13 (rounded to two decimal places)

Substituting the value of a into equation 1 (or 2), we get:

14.69 = 34(0.13) + b

b = 14.69 - 4.42

b = 10.27

Therefore, the linear function that represents the monthly cost in terms of total calling time is:

C = 0.13T + 10.27

To find the monthly cost for 39 minutes of calls, we can substitute T = 39 into this function:

C = 0.13(39) + 10.27

C = 5.07 + 10.27

C = $15.34 (rounded to two decimal places)

Therefore, the monthly cost for 39 minutes of calls is $15.34.

The cost price (CP) is the original price paid to purchase a product or asset. It is the total cost incurred to acquire or produce the item, including all direct and indirect costs such as the cost of raw materials, labor, overhead expenses, transportation, taxes, etc.

The cost price is an important factor in determining the profitability of a business or investment, as it directly affects the profit margin. The profit margin is the difference between the selling price (SP) and the cost price (CP), expressed as a percentage of the cost price.

Profit Margin = (SP - CP) / CP * 100%

For example, if a product is sold for $100 and the cost price is $70, then the profit margin is:

Profit Margin = ($100 - $70) / $70 * 100%

Profit Margin = 30%

This means that for every $1 of cost, the business makes a profit of $0.30. The profit margin can be used to evaluate the efficiency and competitiveness of a business, and to compare the profitability of different products or investments.

Answer: To find the percent increase in population, I used the following formula:

percent increase = (new value - old value) / old value * 100

In this case, the old value was the population from a decade ago (4360), and the new value was the current population (6590). So plugging these values into the formula, we get:

percent increase = (6590 - 4360) / 4360 * 100

percent increase = 51.38%

So the population of Placerville increased by approximately 51.38% over the past decade. The population of Placerville has increased by (6590 - 4360) = 2230 people over the past decade.

Therefore, 11/2 + 3/4 expressed as a fraction is 25/4.

A fraction is a number that represents a part of a whole. It is represented as a ratio of two numbers, the numerator and the denominator, separated by a horizontal line. The numerator represents the number of parts, while the denominator represents the total number of parts that make up the whole. Fractions can be expressed in different forms, including proper fractions, improper fractions, and mixed numbers. A proper fraction is a fraction where the numerator is less than the denominator. An improper fraction is a fraction where the numerator is greater than or equal to the denominator. A mixed number is a combination of a whole number and a proper fraction.

Here,

5 1/2+3/4

5 1/2=5*2+1/2

=11/2

11/2+3/4

To add 11/2 and 3/4, we need to find a common denominator. The smallest common multiple of 2 and 4 is 4, so we can rewrite 11/2 as an equivalent fraction with a denominator of 4:

11/2 = (11/2) x (2/2) = 22/4

Now we can add the two fractions:

11/2 + 3/4 = 22/4 + 3/4

To add the two fractions, we add the numerators and keep the same denominator:

    The area of the right triangle would be: Area = 1/2 * base * height

if the area of the triangle is 18 square inches, then h = 2(18)/6 = 6 inches.

If the base, b, is 6 inches, and the area, A, is 18 square inches, then the height, h, of the triangle is 6 inches.

Triangle is a three-sided geometric shape that has three angles and three sides. The three sides of a triangle are typically referred to as the base, the height, and the hypotenuse. A triangle can be classified as either right, obtuse, or acute depending on the measure of its angles. Right triangles have one right angle, obtuse triangles have one obtuse angle, and acute triangles have three acute angles.

The area of a right triangle can be found by using the formula A=1/2bh, where b is the base of the triangle and h is the height. In this example, the base, b, is 6 inches. To find the height, h, we can solve the equation for h: h = 2A/b, where A is the area of the triangle.

Therefore, if we know the area of the triangle, A, we can find the height, h, of the triangle by plugging in the values and solving for h. For example, if the area of the triangle is 18 square inches, then h = 2(18)/6 = 6 inches.

The area of a right triangle can be found by using the formula A=1/2bh and plugging in the known values of b and h. In this example, if the base, b, is 6 inches, and the area, A, is 18 square inches, then the height, h, of the triangle is 6 inches.

Answer:

Let's start by figuring out how many blue beads Ann had initially.

If Ann had a total of 285 red and blue beads, and she used 45 red beads, then she had 240 blue beads remaining.

If Ann used 40% of the blue beads, then she used:

0.40 x 240 = 96 blue beads

After using 45 red beads and 96 blue beads, Ann had the following number of red and blue beads remaining:

Red beads = 285 - 45 = 240

Blue beads = 240 - 96 = 144

At this point, the ratio of red beads to blue beads is:

Red beads : Blue beads = 240 : 144 = 5 : 3

However, we want the ratio to be 1 : 3. To achieve this ratio, we need to divide both the red beads and blue beads by 5. This gives us:

Red beads = 240 / 5 = 48

Blue beads = 144 / 5 = 28.8

Since we can't have a fraction of a bead, we need to round up the number of blue beads to the nearest whole number. This gives us:

Red beads = 48

Blue beads = 29

Therefore, Ann initially had 285 - 48 - 29 = 208 beads, with 48 red beads and 29 blue beads.
