Answer:
A and D
Step-by-step explanation:
Since tangent is opposite/adjacent,
Tan 40 in this case would be x/3.8 (i used x because we don't know what the value is)
So, you set it up as an algebra problem
Tan40 = x/3.8
Multiply both sides by 3.8
3.8tan40 = x, Option A
And then, angle E is 50 degrees
So tan 50 = 3.8/x
Multiply both sides by x
tan50x = 3.8
Divide both sides by tan50
x= 3.8/tan50
So, A and D are both correct

Answer:
You will put 1220.83ft³ of water in the pool
Step-by-step explanation:
radius = half of diameter
d = 18ft
r = 18ft / 2 = 9ft
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 6ft
π = 3.14
r = radius = 9ft
v = (π * r²) * h
we replace with the known values
v = (3.14 * (9ft)²) * 6ft
v = (3.14 * 81ft²) * 6ft
v = 254.34ft² * 6ft
v = 1526.04ft³
The volume of the cylinder is 1526.04ft³
If it is filled to 80% then we have to multiply the volume by 80/100
1526.04ft³ * 80/100 = 1220.83ft³
You will put 1220.83ft³ of water in the pool
Answer:
- 12=0.005×w
- the number is 2400
Step-by-step explanation:
An appropriate representation of the problem can be had by using a variable to represent "what number" and then using the math equivalent symbols for the English words. If "what number" is represented by w, then we want to translate ...
0.5% of w is 12 . . . . English
0.005 × w = 12 . . . . . . . matches choice 1
__
This can be solved by multiplying by 200
200(0.005w) = 200(12)
w = 2400
The number is 2400.
