He can multiply 1/2 by 3/3 which makes it 3/6 so now 4/6 and 3/6 have common denominators.

Answer:

81

Step-by-step explanation:

Given the relationships \(a \propto y^2\) and \(b \propto \frac{1}{y}\), let's solve for the proportionality constants and then use them to find \(x\) when \(y = 4\).

From the given values:

1. When \(x = 18\) and \(y = 2\), we have \(a + b + 4 = 18\).

2. When \(x = -3\) and \(y = 1\), we have \(a + b + 4 = -3\).

We can set up two equations using the given proportionalities and the given values:

Equation 1: \(a = ky^2\)

Equation 2: \(b = \frac{c}{y}\)

Substituting these into the first given condition:

\(ky^2 + \frac{c}{y} + 4 = 18\)

Substituting these into the second given condition:

\(ky^2 + \frac{c}{y} + 4 = -3\)

Solving these two equations will allow us to find the constants \(k\) and \(c\), and then we can use them to find \(x\) when \(y = 4\).

Let's solve the equations:

From the first equation:

\(k(2^2) + \frac{c}{2} + 4 = 18\)

\(4k + \frac{c}{2} + 4 = 18\)

\(4k + \frac{c}{2} = 14\)

From the second equation:

\(k(1^2) + \frac{c}{1} + 4 = -3\)

\(k + c + 4 = -3\)

\(k + c = -7\)

Now we have a system of two equations:

1. \(4k + \frac{c}{2} = 14\)

2. \(k + c = -7\)

Solve the second equation for \(k\): \(k = -c - 7\)

Substitute this into the first equation:

\(4(-c - 7) + \frac{c}{2} = 14\)

\(-4c - 28 + \frac{c}{2} = 14\)

\(-8c - 56 + c = 28\)

\(-7c = 84\)

\(c = -12\)

Substitute \(c\) back into \(k + c = -7\):

\(k - 12 = -7\)

\(k = 5\)

Now that we have \(k\) and \(c\), we can determine the values of \(a\) and \(b\) using the given proportionalities:

\(a = 5y^2\)

\(b = \frac{-12}{y}\)

Finally, substitute these values of \(a\), \(b\), and \(y\) into the equation \(x = a + b + 4\) to find \(x\) when \(y = 4\):

\(x = 5(4^2) + \frac{-12}{4} + 4\)

\(x = 80 - 3 + 4\)

\(x = 81\)

So, when \(y = 4\), \(x\) is 81.

Step-by-step explanation:

1/2 = 20/40, and 1 = 40/40. 36 is 4 away from 40, and 20 is 20 away from 40. Therefore, 36/40 is closer to 1 than it is 20/40, or 1/2. Hope this helps! Have a great day! :)

Step-by-step explanation:

Answer: A

Step-by-step explanation:

cakes = x pies = y

total number of cakes and pies sold: 75

so x + y = 75

Total money earned: $340

so $4 of x amount cakes + $5 of pies sold =$340

So,

x + y = 75

4x + 5y = 340

Answer: (-1, 3)

Step-by-step explanation:

x = -1

y = 3

3 = -1 + 4

-1 + 3 = 2

Answer:

(-1, 3)

Step-by-step explanation:

One way to solve this is to simply plug the points into the equations, and see if both equations hold true.

(1, 5)

5 = 1 + 4 is true

However

1 + 5 = 2 is not true, therefore this isn't the answer.

(0, 2)

2 = 0 + 4 isn't true so we can move on to the next point.

(-1, 3)

3 = -1 + 4 is true

and

-1 + 3 = 2 is also true

Therefore, (-1, 3) is the answer.

Answer:

The data has a range of 11, which is a wide spread. This means that there is a large difference in the number of flights taken by the students, with one student having taken 11 more flights than the student who took the least number of flights recorded. In this situation, the spread of the data indicates that some students have taken significantly more flights than others.

The data has a range of 6, which is a wide spread. This means that there is a difference of 6 flights between each of the students.

The difference between the highest and lowest values in a data collection indicates the range of that data set.

The dot plot displays the frequency of each amount observed, so:

The lowest number is of 5.

The highest number if of 11.

The linear regression equation that represents this set of data is given as follows:

y = 1.05x - 10.43.

The estimated homework grade for a student with a test grade of 31 is given as follows:

39.46.

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.

The points for this problem are given as follows:

(58, 52), (75, 66), (66, 68), (85, 74), (53, 38), (74, 65), (78, 76).

Inserting these points into a calculator, the equation is given as follows:

y = 1.05x - 10.43.

The estimated homework grade for a student with a test grade of 31 is x when y = 31, hence:

31 = 1.05x - 10.43

x = 41.43/1.05

x = 39.46.

The area not frosted in the bottom layer of the cake is 680 square inches. This can be calculated by identifying the total area and the frosted in both the cube-shaped layers and subtracting the same.

Given, the sides of the cube on top are 6 inches, the sides of the cube below are 10 inches. To calculate the total surface area of cake = surface area of top layer + surface area of bottom layer) = [tex](side^{2} *number of sides + side^{2} *number of sides)[/tex]

= 6*6*6+10*10*6 = 816 square inches.

Let us calculate the total area of the cake that is not frosted, = (area of bottom+area of connection) = [tex]side*side + side *side[/tex]= 6*6+10*10 = 136 square inches. To find the area of the cake that is not frosted on the bottom layer,

=(total surface area of the cake - total area of the cake not frosted)

= 816 - 135 square inches = 680 square inches. Therefore, the total area not frosted on the bottom layer is 680 square inches.

Answer:

Abdul can rent the boat for at most 5 hours.

Step-by-step explanation:

Let's call the number of hours Abdul rents the boat "t".

The cost of renting the boat without the discount coupon is $8 per hour, so the cost would be 8t dollars.

With the discount coupon, the cost of renting the boat would be 8t - 5 dollars.

We know that Abdul wants to spend at most $35, so we can write the inequality:

8t - 5 ≤ 35

Solving for t, we get:

8t ≤ 40

t ≤ 5

Therefore, Abdul can rent the boat for at most 5 hours.

Answer:

Therefore, the car uses gas at a rate of 21 miles per gallon.

Step-by-step explanation:

If Violet's car used 5/6 of a gallon to travel 17 1/2 miles, we can find the rate at which the car uses gas (in miles per gallon) by dividing the distance traveled by the amount of gas used.

To do this, we need to convert the mixed number 17 1/2 to an improper fraction:

17 1/2 = 35/2

So, the rate at which the car uses gas is:

(35/2) miles ÷ (5/6) gallons

To divide by a fraction, we can multiply by its reciprocal:

(35/2) miles ÷ (5/6) gallons = (35/2) miles x (6/5) gallons

Simplifying, we get:

(35/2) x (6/5) = (35 x 6)/(2 x 5) = 210/10 = 21

Therefore, the car uses gas at a rate of 21 miles per gallon.

Answer:nonlinear i think

Step-by-step explanation:

The surface area of a cylinder can be found by adding the areas of the top and bottom circles, as well as the area of the side (lateral) surface.

The radius of the cylinder is 1 and one fourth centimeters, which can be written as 5/4 cm. The height of the cylinder is 3 and three fourths centimeters, which can be written as 15/4 cm.

The area of each circle is πr^2, where r is the radius. So, the area of the top and bottom circles is:

2π(5/4)^2 = 25/2 π square centimeters

The lateral surface area of a cylinder is given by the formula 2πrh, where r is the radius and h is the height. So, the lateral surface area of the cylinder is:

2π(5/4)(15/4) = 75/2 π square centimeters

Therefore, the total surface area of the cylinder is:

25/2 π + 75/2 π = 100/2 π = 50 π square centimeters

So, the exact surface area of the cylinder in terms of π is 50π square centimeters. None of the given options matches this answer.

You want to factor out the greatest common factor from ...

The greatest common factor is the largest expression that is a factor of both terms. Here, one term is a constant, so the GCF will be the largest constant that is a factor of both the coefficient and the constant.

For these numbers, your familiarity with multiplication tables will tell you the greatest common factors. More formally, you can find the GCF a couple of different ways.

You can factor the numbers involved, and identify the set of common factors. The GCF will be the product of the numbers in that set:

Repeatedly divide by the smaller of the two numbers or the remainder, until the remainder is 0. The last divisor is the GCF.

Factoring out the greatest common factor, we have ...
