Answer:
it's d
Step-by-step explanation:
because you first do 3*4 =12 twice because there are two sides, and do 10*3 twice, and 10*4 twice, and add it all up.
so,
24+60+80=164
answer is d.
Answer:
The horizontal distance between the parking lot and the launch site is 470 meters
Step-by-step explanation:
Let
x-----> the horizontal distance between the parking lot and the launch site
we know that
The tangent of angle of 12 degrees is equal to divide the altitude of 100 meters by the horizontal distance
so
tan(12°)=100/x
Solve for x
x=100/tan(12°)=470 meters
Answer:
<u>The difference of a number and 4:</u>
<u>The cube of the difference:</u>
Leaving this as is since no simplification is required.
200 divided by 12 is 16.66666666666667, so about 17 hours.
