Answer: the answer is c
Step-by-step explanation:
25 divided by 400 is 16
We can assume that the point the ladder creates with the ground and building is a triangle. You can use the Pythagorean theorem to solve this.
A^2 + B^2 = C^2
The ladder is C, and the building can act as A or B, so for the purpose of this explanation, I’ll make it A.
11^2 + B^2 = 14^2
Figure out the squares
121 + B^2 = 196
Subtract 121 from both sides
B^2 = 75
Square root B^2 and 75
B = 5 root3
Answer:
x = -2
Step-by-step explanation:
x+8 = 2x +10
-2x + x = 10-8
-x = 2
divide both side by -1
answer -- x = -2
Answer:
2,139.5 lbs
Step-by-step explanation:
A certain vehicle weighs 3,890 lbs.
The front wheels carry 55% of the weight.
Then,
3,890 lbs - 100%
x lbs - 55%
Write a proportion:

Cross multiply:


Answer:
Lateral Area = 13 x 13 x 4 = 676 ft²
Surface area = 13 x 13 x 6 = 1014 ft²
Volume = 13 x 13 x 13 = 2197 ft³
