Answer:

second coupon with 15% off

Step-by-step explanation:

366.99-50= 316.99(first coupon )

366.99×( 100%-15%)= 311.9415 (second coupon)

316.99>311.9415

so the second coupon is the one she should use

find the median of this set of numbers 5,11,2,12,4,2

Answers

Step-by-step explanation:

2,2,4,5,11,12

the median is 5

Answer:

2, 2, 4, 5, 11, 12 (put the numbers from least to greatest)

since it's an even set of numbers, the median is between two of the numbers. so find where the middle is by counting how many numbers you have, and then dividing by 2. in this case it's 3, so there should be 3 values on either side of the median. so the median is between 4 and 5. So you add those two values together and divide by 2 (because that's how many numbers you added) and you get 4.5 as your median.

Step-by-step explanation:

The triangles are similar.

Answers

x=12 because say if we choose the base line as our example then the baseline for the small triangle is 7 and the baseline for the bigger triangle is 28. To get from 7 to 28 you have to times by 4 , so the triangle has been enlarged by 4. If we get the side where it says 25 (for the smaller triangle) we can times it by 4 to get 100. Our equation is now 100=6x+28. To work this equation out you do -28 for both sides which equals to 72=6x.
Then we divide by 6 on both sides to get our answer as 12=x

Write an equation of the line with the given slope and y-intercept.

Answers

Answer:

A. [tex] y = \frac{1}{4}x + 2 [/tex].

Step-by-step explanation:

Equation of a line in slope-intercept form, is given as [tex] y = mx + b [/tex].

Given a slope (m) of ¼, and y-intercept (b) of 2, we can get the equation if the line by substituting m = ¼, and b = 2 into [tex] y = mx + b [/tex].

Thus, the equation of the line would be:

[tex] y = \frac{1}{4}x + 2 [/tex].

The entry fee to a fun park is $20. Jackson spent a total of 35 at the park. If z represents the number of rides jackson went on, which equation represents the situation and what is the value of z that makes the equation true?

A= 2.50=35
x=14

B= 2.50z=20
x=8

C= 20z+2.50=35
c=2

D= 20+2.50z=35
x=6

Answers

Answer: The answer is d.

Step-by-step explanation:

If the entry amount is $20 then you want to subtract $20 from $35 and that leaves you with $15 now if you divide $15 in $2.50's you get 6

Triangle ABC is shown the measure of the interior angle at point A is 40 and the exterior angle point C is 102

Answers

Answer:

∠C (Interior) =78°

∠B (Interior) = 62°

Step-by-step explanation:

Given:

∠A (Interior) = 40°

∠C (exterior) = 102°

Computation:

∠C (Interior) = 180° - 102°

∠C (Interior) =78°

∠B (Interior) = 180° - ∠A (Interior) - ∠C (Interior)

∠B (Interior) = 180° - 78° - 40°

∠B (Interior) = 180° - 118°

∠B (Interior) = 62°

Step-by-step explanation:

let the number be 7x &3x

now,

7x+3x= 50

10x=50

x=50

x=5

again,

7x=7×5 = 35

3x= 3×5 =15

therefore the two number are 35 & 15.

Scientists often write very large or very small numbers using exponents. How might a scientist write the number shown using exponents?

Answers

Answer:

It makes comparing magnitudes easier. It is much easier to estimating numbers easier. you can easily say that 0.0000000009 is smaller than 0.0000001 and even say but how much, and it reduces the amount of time you have to read the number, since instead of having 0s, you have the amount of 0s.

Solve the quadratic equation by completing the square.

Answers

Answer:

x'1 = -1

x'2 = 8

Step-by-step explanation:

Answer:

x = - 1, x = 8

Step-by-step explanation:

Given

x² - 7x - 8 = 0 ( add 8 to both sides )

x² - 7x = 8

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- [tex]\frac{7}{2}[/tex] )x + [tex]\frac{49}{4}[/tex] = 8 + [tex]\frac{49}{4}[/tex] = [tex]\frac{81}{4}[/tex]

(x - [tex]\frac{7}{2}[/tex] )² = [tex]\frac{81}{4}[/tex] ( take the square root of both sides )

x - [tex]\frac{7}{2}[/tex] = ± [tex]\sqrt{\frac{81}{4} }[/tex] = ± [tex]\frac{9}{2}[/tex] ( add [tex]\frac{7}{2}[/tex] to both sides )

x = [tex]\frac{7}{2}[/tex] ± [tex]\frac{9}{2}[/tex]

Thus

x = [tex]\frac{7}{2}[/tex] - [tex]\frac{9}{2}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1

x = [tex]\frac{7}{2}[/tex] + [tex]\frac{9}{2}[/tex] = [tex]\frac{16}{2}[/tex] = 8
