Answer:
let's write it as an equation
speed in m/sec (s) = 33.3 -9.81s
speed in m/sec (2.8) = 33.3 -9.81*2.8 = 5.832
9.81 is the deceleration due to earth's gravity.
the speed changes that ammount per second.
Answer:
Hey are you trying to find the vaule of x?
Step-by-step explanation:
Here we MUST do the exponentiation first, followed by the mult. The add'n. is done last.
81 + 4(9) = 81 + 36 = 117 (answer)
We can use ratios to find the answer to this.
Set up the ratio.
3/4 / 18/7 = x / 1
Multiply both sides by 1
3/4 / 18/7 = x
Inverse 18/7 to 7/18 so we can multiply.
3/4 * 7/18 = x
Multiply.
21/72 = x
Simplify7/24 = x
Therefore, 7/24 cups of oats is used per pound.
Answer:
a. The tree is 30 feet tall.
b. The tree is 24 feet taller than Frank.
Step-by-step explanation:
Since the shadow of the tree is 20 feet and the shadow of Frank is 4 feet, 20+4 is 24. 24+6 is 30, so the tree is 30 feet tall and the tree is 24 feet taller than Frank.
