Answer:
The expression to find Carey's hourly rate is: 
. Carey's hourly rate is $10.
Step-by-step explanation:
Anderson receives 1 more than half of carey's hourly rate. If we call Anderson's rate by "a" and Carey's by "c", we can express this phrase in the following equation:
We want to find the Carey's rate, therefore we need to isolate the "c" variable.
Since Anderson earns $6, then we can find Carey's rate:
Answer:
n = 3/5
Step-by-step explanation:
Represent this quotient as:
n
---------
-2/3
and set it equal to -9/10:
n -9
--------- = -------
-2/3 10
Cross multiplication yields:
10n = 6, so that n = 6/10 or n = 3/5
Answer:
12/13
Step-by-step explanation:
Use SOH-CAH-TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
sin B = opposite / hypotenuse
The side opposite of angle B is side b. The hypotenuse is c.
sin B = b / c
sin B = 12 / 13
That would be 6.64 / 1.35 = 4.9 times (to the nearest tenth.)
