Answer:
60
Step-by-step explanation:
X*0.35=21
X=21/0.35
X=60
Answer:
D
Step-by-step explanation:
Using sine rule
a/sin A =b/sin B
8/sin90° = x/sin60°
8 * sin60° = x
x =

Answer:
Circumference= 44 in
Area= 154 in²
Step-by-step explanation:

Radius
= diameter ÷2
= 14 ÷2
= 7 in
Circumference of circle

= 44 in

Area of circle

= 154 in²
Answer:
d. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.
Step-by-step explanation:
This would be a function as long as one x-value doesn't correspond to two y-values. If two x-values correspond to one y-value though, it still represents a function.
√m/3 = 4
To remove the radical sign, square both sides.
(√m/3)² = 4²
m/3 = 16
To remove the denominator of 3, multiply both sides by 3.
3 (m/3) = 3(16)
m = 48
To check: Substitute m by its value.
√m/3 = 4
√48/3 = 4
√16 = 4
4 = 4
