Answer:
35.67
Step-by-step explanation:
3x - 31 = 76
+ 31 + 31
3x = 107
/3 /3
x = 35.6667
3^2 * 3^5 =
3*3=9 * 3*3*3*3*3= 243
I think you can figure out it from there
Answer:
600
Step-by-step explanation:
2000/10=200. 200x3=600
Last week, the Glee Club made 437 flowers. They made 322 more this week than last week. So this could be shown in this case as 437 + 759 (since 437 + 322 = 759). This equals 1,196 flowers. To find the remaining number of required flowers, we could represent this equation as 1,196 + x = 1,250, with x representing the number of flowers still needed. Since 1,250 - 1,196 = 54, they still need to make 54 paper flowers for their parade float. Substituted back into the equation, it would look like this:
1,196 + 54 = 1,250.
Answer:
D. 25pi
Step-by-step explanation:
"circumscribed" means the rectangle is inside the circle and just the corners (vertices) of the rectangle are touching the circle. This means the diagonal of the rectangle is the diameter of the circle. See image. If the sides of the rectangle are 6 and 8 then the third side that makes the triangle(half the rectangle) is 10. You can find this using Pythagorean Theorem or Pythagorean triples (shortcut)
6^2 + 8^2 = d^2
36 + 64 = d^2
100 = d^2
d = 10
This is the diameter of the circle. The radius would then be 5.
Area of a circle is:
A = pi•r^2
= pi•5^2
= 25pi
