Answer:
Hi there!
Your answer is:
The length is 75
Step-by-step explanation:
P=180
L=5w
Perimeter formula
L+L+W+W=P
Plug in known values
5W+5W+W+W=180
12W=180
/12
W=15
Plug in width in length formula!
L=5W
L=5(15)
L=75
Here we have a 90 degrees triangle where we can use trigonometric functions.
Here we can use tan(x) function because it requires legs of triangle that are given and inverse function of tan(x) will than give us asked angle
tan(x) = 7.4/9.3 = 0.7956
x = arctan(0.7956) = 38.505 ≈ 39 degrees.
Answer:
8p=c
Step-by-step explanation:
For questions like this, it isn't asking for a numerical answer or anything complicated. It's mainly just using common sense and figuring out what you would do if you had actual numbers instead of variables. You would multiply the amount of pounds (p) by the cost per pound of $8, and that would be your answer (c). I hope I could help.
Answer:
double the radius.
Step-by-step explanation:
Quadruple means 4 times. So you want to make the volume 4 times larger than it currently is.
This can be a little nasty because both numbers are the same.
V = 1/3 pi * r^2 * h
V = 1/3 3.14 * 4.8^2 * 4.8
V = 115.75296
Now if you double the radius, the volume becomes 4 times larger (or it should)
V= 1/3 * 3.14 * (9.6)^2 * 4.8
V = 463.012
Did that make the original volume larger?
115.75296 * 4 = 463.012 rounded.
3(3x - 5) + 6 = 12 - 2(x+5)
9x - 15 + 6 = 12 - 2x - 10
9x - 9 = 2 - 2x
9x + 2x = 2 + 9
11x = 11
x = 1
