Answer:
900 feet / 5,280 = 0.1704545... miles
8 seconds / 3,600 = 0.0022222222 hours
0.1704545 miles / 0.0022222222 hours = 76.704525767 miles per hour
The car is well over the speed limit
Step-by-step explanation:
Answer:
it is the surface of the 3d shape spread out like an blue print
Step-by-step explanation:
Q1: The answer is A. pyramid.
A pyramid has one polygon base. A prism has two polygon bases. A cone has one circular base. A cylinder has two circular bases.
Q6: The answer is false.
Surface area of a rectangular prism is:
A = 2(wl + hl + hw)
A1 = 2(4*5 + 6*5 + 6*4) = 2(20+30+24) = 2*74 = 148
A2 = 2(6*4 + 5*4 + 5*6) = 2(24+20+30) = 2*74 = 148
Q7. The answer is A. 6 feet
The volume of rectangular prism is:
V = w * l * h
w = ?
So, just replace the knowing facts:
288 = w * 8 * 6
288 = w * 48
w = 288/48 = 6
Q8: The answer is 216 ft³
The volume of the cube is:
V = a³
Since a = 6, then:
V = 6³ = 216
Answer:
Step-by-step explanation:
in supplementary angle sum of two angles is always 180 degree
let another angle be x
x+151=180
x=180-151
x=29 degree
You complete the square
Vertex form is
![f(x) = (x - h)^2 + k~~~~~~~the~~vertex ~~is~~(h, k)](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%28x%20-%20h%29%5E2%20%2B%20k~~~~~~~the~~vertex%20~~is~~%28h%2C%20k%29)
so break it into parts
![f(x) = (x^2 + 6x + ??) + 8 - ??](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%28x%5E2%20%2B%206x%20%2B%20%3F%3F%29%20%2B%208%20-%20%3F%3F)
to keep the equation in balance to add and subtract the same value
so value ?? is
![?? = ( \frac{6}{2} )^2](https://tex.z-dn.net/?f=%3F%3F%20%3D%20%28%20%5Cfrac%7B6%7D%7B2%7D%20%29%5E2%20)
then factor the perfect square
