10% of 80 = 8

80 - 8 = 72

if they are 10% off, the contact lenses will cost $72

Can someone plz help? Only have a hour...I'll make crown the best and triple the points!!!
kykrilka [37]

Answer:

x= 3.57

Step-by-step explanation:

32 ( x + 2.5) = 114.24

32* x + 32* 2.5= 114.24

32x + 80= 114.24

        -80      -80

32x= 114.24

/ 32    /32

x= 3.57

for the part that says convince me, we can use the eqution

Use the distance formula to find the perimeter. Round to the nearest tenth.
Ierofanga [76]

Answer:

37.6 units

Step-by-step explanation:

Perimeter = sum of all sides of the triangle

To find the sum, find the distance between each points.

✔️Distance between points (-7, 6) and (5, -4):

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} =

= \sqrt{(5 - (-7))^2 + (-4 - 6)^2}

= \sqrt{(12)^2 + (-10)^2}

= \sqrt{144 + 100}

= \sqrt{244} = 15.6 units (nearest tenth)

✔️Distance between (-7, 6) and (-7, -4):

|6 -(-4)| = 10 units

✔️Distance between (-7, -4) and (5, -4)

|-7 - 5| = 12 units

✔️ Perimeter = 15.6 + 10 + 12 = 37.6 units

Consider these functions
Evgen [1.6K]
<h3>Answer:  D) 31</h3>

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

Explanation:

The expression g(f(2)) has f(2) as the inner function.

Let's compute f(2)

This means we plug x = 2 into the f(x) function

f(x) = 4x^3 - 10

f(x) = 4(x)^3 - 10

f(2) = 4(2)^3-10

f(2) = 4*8-10

f(2) = 32-10

f(2) = 22

Now we'll plug this into the g(x) function

This is because g(f(2)) = g(22). I've replaced f(2) with 22

So,

g(x) = (3x-4)/2

g(22) = (3*22-4)/2

g(22) = (66-4)/2

g(22) = 62/2

g(22) = 31

Therefore, g(f(2)) = 31
