Answer:
A) √29 = x B) x = √41.8 C) √109 = x D) x = √489.24
Step-by-step explanation:
A) 2² + 5² = x²
4 + 25 = x²
29 = x²
√29 = x
B) 3.6² + x² = 7.4²
12.96 + x² = 54.76
-12.96 - 12.96
x² = 41.8
x = √41.8
C) 3² + 10² = x²
9 + 100 = x²
109 = x²
√109 = x
D) 7² + x² = 23.2²
49 + x² = 538.24
-49 -49
x² = 489.24
x = √489.24

Answer:
- 3 packages of American (7/8 lb)
- 2 packages of cheddar (1/2 lb)
Step-by-step explanation:
The amount of cheese Mrs Mack needs is an odd number of eighths of a pound. So, she must buy an odd number of the 7/8 pound packages.
If she were to buy any 1/5 pound packages, she would have to buy a multiple of 5 of them so as to have an integral number of eighths. The only suitable multiple is 0.
If Mrs Mack buys 1 of the 7/8 pound packages, she cannot make up the difference with half-pound packages. She must buy 3 of the 7/8 pound packages, for a total of 2 5/8 pounds of American cheese. The remaining pound can be bought as 2 of the 1/2 pound packages.
To buy 3 5/8 pounds, Mrs Mack must purchase ...
3 packages of American cheese (7/8 lb each)
2 packages of Cheddar cheese (1/2 lb each)

It's 248 ft because it increased by 24%, you do 200 ft times 1.24 to get 248 ft.
Answer:
Surface area of sphere = 4πr²
r = radius
and radius = diameter/2
radius = 13/2
= 6.5cm
Surface area = 4 × π × 6.5
= 26 × π
= 81.68
= 81.7cm²
Hope this helps.
