Answer: 3400
Step-by-step explanation:
We have, 5% × x = 170
or,
5
100
× x = 170
Multiplying both sides by 100 and dividing both sides by 5,
we have x = 170 ×
100
5
x = 3400
If you are using a calculator, simply enter 170×100÷5, which will give you the answer.
Answer:
9000
Step-by-step explanation:
the equation to figure this out would be 180(n-2). N would equal the number of sides so you would plug it in 180(52-2). Then you end up with 180*50 which equals 9000
1000/20 is the same as 100/2(you just removed a 0 from both of them)
10/2=5 add a 0
50
The surface area of a cone is equal to the base plus the lateral area.
The base is a circle, and has a diameter of 16 meters.
The radius is always half the diameter, so it is 8 meters.
The area of a circle = πr², where r is the radius. π(8)² = 64π ≈ 201.06193
The area of the base is ≈ 201.06193.
To find the lateral area of the cone, we need to find the slant height.
Since the height, radius, and slant height of the cone form a right triangle, we can use the Pythagorean Theorem to find the slant height with what we are given.
radius² + height² = slant height²
8² + 37² = slant height²
64 + 1369 = slant height²
1433 = slant height²
slant height = √1433
The lateral area of a cone is equal to πrl, where r = radius and l = slant height.
πrl = π(8)(√1433) ≈ 951.39958
(there are other formulas which do the same thing, but it doesn't matter.)
Now we add the lateral area and base together to find our surface area.
201.06193 + 951.39958 = 1152.46151 which rounds to C. 1,152 m².
First, divide each side by 4 to get y alone on the left side.
y=-6/4x+2
The y intercept is 2
