Answer:
A
Step-by-step explanation:
Remarks
- The given angle is an exterior angle.
- It's value is 46 degrees.
- An exterior angle is the sum of the two remote angles. (A remote angle is one that is not supplementary to the given exterior angle.
Solution
- 46 = <u + <t
- <t = 29
- 46 = <u + 29 Subtract 29 from both sides.
- 46 - 29 = <u
- <u = 17 degrees
I believe the answer would be 50
explanation:
calculate
2 ÷ 5^-2
use negative power rule x^-a = 1/x^a
2 ÷ 1/5^2
simply 5^2 to 25
2 ÷ 1/25
use this rule a ÷ b/c = a • c/b
2 • 25
simplify
50
Note the coordinates of each point: R(-4, 5), S(5, 1), T(2, -3).
The centroid is the point whose coordinates are the average of the coordinates of R, S, and T.
<em>x</em>-coordinate: (-4 + 5 + 2)/3 = 3/3 = 1
<em>y</em>-coordinate: (5 + 1 - 3)/3 = 3/3 = 1
So the centroid is (1, 1).
C-Cost because it the most reasonableness one
Volume of the sheet cake:
V ( prism ) = 12 * 9 * 2 = 216 in³
Volume of the birthday cake:
V ( cylinder ) = r² * π * h = 4.5² * 3.14 * 4 = 254.34 in³
Then we will use the proportion :
216 : 254.34 = 36000 : x
216 x = 254.34 * 3600
216 x = 915,660
x = 915.660 : 216
x = 4,239.17 ≈ 4,240
Answer:
d. 4,240
