Answer:
Correct answers:
A. An angle that measures radians also measures
C. An angle that measures also measures radians
Step-by-step explanation:
Recall the formula to transform radians to degrees and vice-versa:
Therefore we can investigate each of the statements, and find that when we have a radians angle, then its degree formula becomes:
also when an angle measures , its radian measure is:
The other relationships are not true as per the conversion formulas

Step-by-step explanation:
1) Identify the equation of the surface area of a rectangular prism
2) Input the corresponding values ; ; and into the equation, and solve for the area
3) ∴
Answer:
D
Step-by-step explanation:
The area of a circle can be found using:
a=πr^2
We know that the radius is 10 meters. Therefore, we can substitute 10 in for r.
a=π*10^2
Evaluate the exponent
a=π*100
Multiply pi and 100
a=314.159265359
Round to the nearest tenth: there is a 5 in the hundreth place, which indicates we round up the 1 in the tenths place to a 2.
a=314.2
The area is 314.2 square meters, or choice D
30+6t - 3t-9
combine 6t and -3t and get 3t
30+3t=-9
subtract 30 on both sides
3t=-39
divide by 3
t=13
Since Sydney has planted 5/9 of her flowers and there were 63 flowers that are left unplanted, the first thing we are going to determine is the number of flowers that were planted. To do this, we just have to do the cross multiplication process.
So 5/9 x ?/63 = 35. Therefore, the number of plants planted were 35. To start, Sydney has a total of 100 flowers to be planted. That would be 35 + 65 is 100.
