Answer:

3ft

Step-by-step explanation:

c^2 = a^2 + b^2 so, we have c = 5ft, and lets call this one a = 4ft

so: x^2 = 5^2 - 4^2 => x = sqrt(25 - 16) => x = 3ft

Lee has a jar of 100 pennies. She adds groups of 10 pennies to the jar. She adds 5 groups. What numbers does she say?

kherson [118]

If Lee starts with 100 pennies and adds groups of 10, the operation is addition. Since she does this 5 times, there is 5 different numbers Lee said.

100 + 10 = 110
110 + 10 = 120
120 + 10 = 130
130 + 10 = 140
140 + 10 = 150

Thus, all of the numbers she said were 110, 120, 130, 140, and 150.

Hope this helps! :)

Soooo Hard<br> Please someone help me

Alisiya [41]

$\frac{1}{2} ( \frac{2}{3} + \frac{3}{4}) \\ = \frac{1}{2} ( \frac{2 \times 4}{3 \times 4} + \frac{3 \times 3}{4 \times 3} ) \\ = \frac{1}{2} ( \frac{8}{12} + \frac{9}{12} ) \\ = \frac{1}{2} ( \frac{8 + 9}{12} ) \\ = \frac{1}{2} ( \frac{17}{12} ) \\ = \frac{1 \times 17}{2 \times 12} \\ = \frac{17}{24}$
The answer is 17/24
