Answer:
The distance that Mrs. Gilbertson's daughter walked was 188.4 feet
Step-by-step explanation:
Here we have that Mrs. Gilbertson's daughter walked round the circle 12 times where the diameter of the circle = 5 ft., therefore, the circumference of the circle, the distance walked round each of the 12 times = π·D
Where:
D = 5 ft
Hence, circumference = π × 5 = 3.14 × 5 = 15.7 ft
Therefore, by walking round the circle 12 times, the total distance that Mrs. Gilbertson's daughter walked = 12 × 15.7 = 188.4 ft.
Answer:
1 5/7
Step-by-step explanation:
divide 12 by 7
- For the remainder you will get 5 .
- And on the top it will be 1 .
- So 1 is going to be the whole number and 5 is going to be the numerator.
- and 7 is going to be the denumerator.
- Make sure the number you are dividing is always the denumerator
EXAMPLE:
5/3 = 1 R2 1 2/3
edge is 2 times as long : volume is 8 times as big, edge is 3 times as long : volume is 27 times as big, edge is 10 times as long: volume is 1000 times as big, edge is n times as long, volume is n^3 times as big.
Since the volume of a cube can be given by V = s^3 where s is the edge length, and V Is the volume of the cube. The change in volume relative to the change of its edge is ∆v/∆s = 3s^2 (derivative).
First you need to find on interior angle of a triangle. We know that the polygon has 13 sides and we also know that all of the exterior angles have to add up to 360 degrees. We have to divide the number of sides by 360
360/13=27.69
So one exterior angle is about 27.69 degrees.
(If you want to check you can multiply the number of sides by one angle measure to see if it is right)
27.69*13=359.9
Thats about as close as you can get.
Hope it helps! :)
Hello from MrBillDoesMath!
Answer: x 37.2
Discussion:
3x + 7(x-18) = 246 =>
3x + 7x - 7*18 = 246 =>
10x - 126 = 246 =>
10x = 246+ 126 = 372 =>
x = 37.2
Thank you,
