Answer:
length = 63 ft; width = 10.5 ft
Step-by-step explanation:
Let the width be x.
The length is 6 times the width, so the length is 6x.
The perimeter is the sum of 2 lengths and 2 widths.
6x + 6x + x + x
The perimeter equals 147 ft.
6x + 6x + x + x = 147
14x = 147
x = 10.5
The width is 10.5 ft.
The length is 6x, so the length is 6 * 10.5 ft = 63 ft
Answer:
11 + x + 19*x
Step-by-step explanation:
The sum of eleven, a number, and the product of nineteen and the number.
we have to read carefully and understand how to interpret
when he says the sum of separates into 3 parts because there is a "comma" and an "and"
Now let's separate the 3 parts of the sum
1 part
says eleven so we just put 11
eleven = 11
2 part
in the text it says that we replace "a number" with x
a number = x
3 part
In this case we simply make the product between the given values
the product of nineteen and the number
19 * x
Now we can accommodate everything and we finish
11 + x + 19*x
The first answer is 2.5 and I don’t know the last two sorry
Answer: 2000
Step-by-step explanation:
Simple interest is calculated as:
(Principal × Rate × Time) / 100
We then slot the value into the formula. This would be:
720 = (P × 6 × 6)/100
720 × 100 = 36P
72000 = 36P
Principal = 72000/36
Principal = 2000
Answer:
1. t = 0.995 s
2. h = 15.92 ft
Step-by-step explanation:
First we have to look at the following formula
Vf = Vo + gt
then we work it to clear what we want
Vo + gt = Vf
gt = Vf - Vo
t = (Vf-Vo)/g
Now we have to complete the formula with the real data
Vo = 32 ft/s as the statement says
Vf = 0 because when it reaches its maximum point it will stop before starting to lower
g = -32,16 ft/s² it is a known constant, that we use it with the negative sign because it is in the opposite direction to ours
t = (0 ft/s - 32 ft/s) / -32,16 ft/s²
we solve and ...
t = 0.995 s
Now we will implement this result in the following formula to get the height at that time
h = (Vo - Vf) *t /2
h = (32 ft/s - 0 ft/s) * 0.995 s / 2
h = 32 ft/s * 0.995 s/2
h = 31.84 ft / 2
h = 15.92 ft
