do you want an expression?
if so it would be T = 40 + 20h
t = total
h = hour(s)
The answer is <span>B. 196 π mi2

(1) Find radius r:
The area of the circle is:
A = r²π
A = 49π mi²
49π = r²π
49 = r²
r = √49 = 7 mi
(2) Find the surface area of the sphere.
The surface area of the sphere is:
A = 4πr²
r = 7 mi
A = 4π * 7²
A = 4π * 49
A = 196π mi²
Answer:
50²yards
Step-by-step explanation:
Cut the shape into 2 peices. The square has a length of 6yd and base of 8yd. bh=48².The little triangle has a base of 4yd and a length of 6yd. bh/2=12².
48 plus 12 = 50yd²
Answer:
Take your product denominator and divide it by the original. 48÷8=6
Since the denominator was increased by a scale factor of 6, the numerator must also be increased by a scale factor of 6 in order to keep the 2 fractions equal. 7×6=42
Hence, your answer is 42/48
Hope this helps?
Answer: 42
Answer:
39x-7
Step-by-step explanation:
The perimeter is all the sides added together so
9x + 8x - 2 + 5x + 1 + 17x - 6
Since you can't solve it you just want to simplify the equation, add the like terms together
9x+8x+5x+17x = 39x
-2+1-6 = -7
Your equation is 39x-7
