Assuming the logarithm is base
![10](https://tex.z-dn.net/?f=10)
, you have
Answer:
10+14c
Step-by-step explanation:
You multiply every number inside the parenthesis by 2.
7y+11+7y+11+7y+11=180(A.S.P)
21y+33=180
21y=180-33
21y=147
y=147/21
y=7
y=7
Answer:
280 ft
Step-by-step explanation:
An auditorium is in the shape of an equilateral triangle with side length as 112 ft.
The stage extends from one vertex of the triangle to the mid-segment and the seating area extends from the mid-segment to the rear wall.
*The situation is represented in the attachment.
According to the midpoint theorem, the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.
Hence, the length of the mid-segment in this case is,
![\dfrac{1}{2}\times 112=56\ ft](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20112%3D56%5C%20ft)
Therefore, the perimeter of the seating area is,
![=112+56+56+56=280\ ft](https://tex.z-dn.net/?f=%3D112%2B56%2B56%2B56%3D280%5C%20ft)
1 Kilometer = 10 Hectometers
= 100 Dekameters
= 1000 Meters
1 Meter = 10 Decimeters
= 100 Centimeters
1 Decimeter = 10 Centimeters
1 Centimeter = 10 milimeters
Just to give you a table of conversion.
<span>Now to get the answer.
500 Meters + 300 Meters = 800 Meters
800 Meters + 10 Kilometers
</span>
You can't add numbers with different units, so you're going to have to convert. So the equation would end up being:
800 Meters + 10000 Meters = 10800 Meters
Since you have to answer it in Kilometers, you're going to have to convert it again to Kilometers. Since 1 Kilometer is equal to 1000 Meters, yo would have to divide 10800 by 1000. So it would turn out like this:
= 10.8 Kilometers
Now, here's what we've done:
500 Meters + 300 Meters + 10 Kilometers
= 500 Meters + 300 Meters + 10000 Meters
= 10800 Meters
= 10.8 Kilometers
