Before Christmas, the price of a shoe in a Heel's Store for Women was $79. At the post-Christmas sale, the price was $43. By wha

BartSMP [9]

Answer:

54.4%

Step-by-step explanation:

Find this by dividing 43 and 79:

$\frac{43}{79}= 0.5443$

Multiply this by 100 to convert to a percent (or just move the decimal to the left two spaces):

$0.5443*100=54.43$

Round to the nearest tenth (one decimal place):

$54.43=54.4$

The price was reduced by about 54.4%

Sara is 6 years older than max in 3 years she’ll be 1 1/2 of max’s age . how old is max ?

Andrews [41]

S = m+6
(s + 3) = (m + 3)1.5
When solved m=9 and s=15
When plugged in it works.
So max is 9 years old

The area of the base of a prism is 50 mm2. The perimeter of the base is 30 mm. The height of the prism is 7 mm.

Flauer [41]

Suppose we have a rectangle with area 50 and perimeter 30. Let's set up equations to find the side lengths.

ab = 50
2a + 2b = 30

Now we need to get one variable alone on one side.

a + b = 15
a = 15 - b

Use substitution and solve.

$a = 15- b\\ (15-b)b = 50 \\ b^2-15b = 50 \\ b^2-15b+50=0 \\ (b-5)(b-10) = 0 \\ \boxed{b=5\ or\ 10}$

So we now know that the square has dimensions 5 and 10. Let's find the surface area.

$SA = 2wl + 2wh + 2lh \\ SA = (2*5*10) + (2*5*7) + (2*10*7) \\ SA = 100 + 70 + 140 \\ \boxed{SA = 310\ u^2}$
