Answer:
a) 512 cm^3
b) 469.125 cm^3
Step-by-step explanation:
8*8*8 = 512 cm^3
or
8^3 = 512 cm^3
3.5^3 = 42.875
512 - 42.875 = 469.125 cm^3
You can round the second answer down
Answer = 5.656854249
Step by step:
This equation is just a simple Pythagorean theorem ( if you were not aware, it’s a2 + b2 = c2. To get c is to find the square root of c)
Answer:
t(h)= (h-200)/-4.9
The time to reach a height of 50 meters is 30.6 seconds
Step-by-step explanation:
To express t as a function of height (h) we must transform the equation below:
h=200-4.9t
h-200=-4.9t
(h-200)/-4.9=t
t(h)= (h-200)/-4.9
To find the time to reach a height of 50 meters, we must replace this value on the new equation:
t(h)=50-200/-4.9
t(h)= 30.612
The time to reach a height of 50 meters is 30.6 seconds
Answer:
Step-by-step explanation:
sales earning commission=130,000-21000=109,000
sales commission=5800-900=4900
rate of commission=4900/109,000 ×100=490/109 %
≈4.495
≈4.50%
Answer:
y=-5x-13
Step-by-step explanation:
use y-y1=m(x-x1)
y+8=-5(x+1)
y+8=-5x-5
subtract 8 from both sides
y=-5x-13
