stira [4]

Answer:

289 in^2

Step-by-step explanation:

1. Find side of the small square: (DG=a)

64= a^2

a= 8

2. Find hypotenuse of triangle being formed: (OG=c and DO=b)

$a^{2}$ + $b^{2}$ = $c^{2}$

$8^{2}$ + $15^{2}$ = $c^{2}$

c= 17

3. Find area of square:

$c^{2}$ = A

(17)*(17)= 289 in^2

Find the product. Write your answer in<br> exponential form.<br> 5^7•5^-9•5^-5

MissTica

5^7 = 5 × 5 × 5 × 5 × 5 × 5 × 5 = 78,125

5^-9 = 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 = 0.000000512

5^-5 = 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 = 0.00032

78,125 × 0.000000512 × 0.00032 = 0.0000128‬

Answer: 0.0000128‬ or 1.28 x 10^-5

lilavasa [31]

Write a system of equations and solve.

x + y = 10
5x + 10y = 90

Multiply and combine equations

-5x - 5y = -50
5x + 10y = 90
------------------
5y = 40
y = 8
x = 2

There are 2 nickels and 8 dimes in the jar. Hope this helps! :)
