Refer to the diagram shown below.
h = the height of the house.
Apply the Pythagorean theorem to obtain
h² + 25² = (25√5)²
h² + 625 = 3125
h² = 3125 - 625 = 2500
h = √(2500) = 50 ft
Answer: The height is 50 ft.
Okay. I think a good way to solve this problem is to write a proportion. 50/75 = x/120. Cross multiply to get 6,000/75x. Now, divide each side by 75 to isolate the “x”. When you do that, you get x = 80. 80 pounds of fertilizer will cover 120 square feet of lawn.
Answer:
Step-by-step explanation:
Given the function
f(x) = 2x³ -3x²+ 7
putting x=-1 to find f(-1)
f(-1) = 2(-1)³ -3(-1)²+ 7
= -2 + 3 + 7
= 8
putting x=1 to find f(1)
f(1) = 2(1)³ -3(1)²+ 7
= 2 - 3 + 7
= 6
putting x=2 to find f(2)
f(2) = 2(2)³ -3(2)²+ 7
= 16 - 12 + 7
= 11
Therefore,
Answer:
√1762
Step-by-step explanation:
Square root of 1762
How?
Well 41^2+9^2=c^2
1681+81=c^2
1762=c^2
c=√1762
Answer: 87.20
explanation: 20 percent is equal to 0.2 so then you multiply 0.2 by $109 which gives you $21.80 so you then subtract $21.80 from $109 and you get $87.20 as your final answer.
