Jim wanted to buy a phone for $250.00. He had a coupon for 15% off. What would be the cost of the phone with the coupon?

Exact answer: [tex]x = \frac{\sqrt{601}}{2}\\\\[/tex]

Approximate answer: [tex]x \approx 12.2577[/tex]

====================================================

How to find the answer:

Focus on the largest triangle. It appears to be a right triangle. If so, then we can use the pythagorean theorem to get the following:

[tex]a^2 + b^2 = c^2\\\\a^2 + 12^2 = 13^2\\\\a^2 + 144 = 169\\\\a^2 = 169 - 144\\\\a^2 = 25\\\\a = \sqrt{25}\\\\a = 5[/tex]

The horizontal leg of the largest right triangle is 5 units long.

The identical single tickmarks tell us that the horizontal leg is cut into two smaller pieces of equal length.

Each smaller piece is 5/2 = 2.5 units long.

------------------------------

Now focus on the smaller skinny right triangle with legs a = 2.5, b = 12 and hypotenuse c = x.

Use the pythagorean theorem again to find the hypotenuse x.

[tex]2.5^2 + 12^2 = c^2\\\\6.25 + 144 = x^2\\\\150.25 = x^2\\\\x^2 = 150.25\\\\x = \sqrt{150.25}\\\\x = \sqrt{\frac{601}{4}}\\\\x = \frac{\sqrt{601}}{\sqrt{4}}\\\\x = \frac{\sqrt{601}}{2}\\\\x \approx 12.2577[/tex]

The expression represents the amount of tip, that Nina will give, when she has a positive experience eating a meal that cost n dollars is [tex]0.18n[/tex]. Hence the option A is the correct option.

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The  algebraic expression are used represent the general problem in the mathematical way to solve them.

Steps to write down the simple algebraic expression-

Given information-

The tip given by the the Nina is 18 percent.

The cost of food is [tex]n[/tex] dollars.

Here the Nina gave the tip of 18 percent. This 18 percent is the percentage of total cost of the food.

Let [tex]f(n)[/tex] is the required expression.

As the the cost of food is [tex]n[/tex] dollars. Thus the 18 percent of [tex]n[/tex] dollars is,

[tex]f(n)=\dfrac{18}{100} \times n\\f(n)=0.18n[/tex]

Thus the expression represents the amount of tip, that Nina will give, when she has a positive experience eating a meal that cost n dollars is [tex]0.18n[/tex]. Hence the option A is the correct option.

Answer:

0,3

Step-by-step explanation:

   6x + 3y = 9

+  -6x + 4y = 12

=

7y = 21

y = 3

Replace 3 into one of the equations and solve for x

6x + 3(3) = 9

6x + 9 = 9

6x = 0

x = 0

The length of material needed for the border is the perimeter of the backyard play area

The area of the play area is given as:

[tex]Area = 286.56[/tex]

The area of a trapezoid is calculated using:

[tex]Area = 0.5 * (L1 + L2) * H[/tex]

Where L1 and L2, are the parallel sides of the trapezoid and H represents the height.

The given parameter is not enough to solve the length of material needed.

So, we make use of the following assumed values.

Assume that the parallel sides are: 25 feet and 31 feet long, respectively.

While the other sides are 10.2 feet and 8.2 feet

The length of material needed would be the sum of the above lengths.

So, we have:

[tex]Length = 25 + 31 + 10.2 + 8.2[/tex]

[tex]Length = 74.4[/tex]

Using the assumed values, the length of material needed for the border is 74.4 feet

y = mx + b.y = 15/13x − 10/13

Answer:

The answer is y = 15x/13 – 10/13.

Step-by-step explanation:

We are given equation

Now, The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

y = mx + b

Rewrite in slope-intercept form.

15x – 13y = 10

Subtract 15x from both sides of the equation we get,

15x – 15x – 13y = 10 – 15x

-13y = 10 – 15x

Divide each term by -13 and simplify.

-13y/(-13) = 10 – 15x ÷ (-13)

Cancel the common factor of -13

y = -10/13 + 15x/13

Now, Rearrange it

y = 15x/13 – 10/13

Thus, The answer is y = 15x/13 – 10/13.

Using the mean concept, it is found that the correct option is given as follows:

A

Football Team Mean: 75"

Basketball Team Mean: 77"

Difference: 2"

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

For the football team, considering the 11 players, it is given by:

M = (72 + 80 + 74 + 76 + 76 + 79 + 78 + 73 + 79 + 68 + 70)/11 = 75"

For the basketball team, it is given by:

M = (78 + 79 + 79 + 80 + 76 + 77 + 77 + 76 + 77 + 74 + 74)/11 = 77"

The difference is the subtraction of the means, hence:

D = 77" - 75" = 2"

Thus option A is correct.

Answer:

ok so this is kinda hard to explain but. what I got out of it was since you are doing you know adding pos with neg so listen when you add something like a pos and a neg you put the pos on top right then you take and put the neg on bottom then you cross out how ever many negatives are there until there is no more negatives left right but that means your also gonna have to cross out how ever many neg there are with positives and if there are more negatives than positives your answer will be negative as well then you just count how many positives arent crossed out and then that would be your answer ect.

  38

Step-by-step explanation:

Sequential pairs will be ...

  38 - 87

  79 - 96

  17 - 74 or 79

  43 - 38

  74 - 43

  96 - (none)

  87 - 74 or 79

We notice that 17 has no preceding number. It must be first in the list. 79 cannot be second, because that skips a bunch of numbers. The sequence appears to be ...

  17 - 74 - 43 - 38 - 87 - 79 - 96

The 4th number in the list is 38.

Step-by-step explanation:

Since DF = EF then the triangle is isosceles with base angle being congruent, that is

∠ D = ∠ E , then

∠ D = [tex]\frac{180-133}{2}[/tex] = [tex]\frac{47}{2}[/tex] = 23.5°

question is equaled to 180 degrees

Answer:

x=110

Step-by-step explanation:

Use the polygon formula (n-2) × 180 where n is the number of points

The polygon has 7 points

(7-2) * 180 = 5 * 180 = 900

All the angles should add up to 900

119+86+167+283+64+71+x=900
