Answer:

m∠B = 76°

Step-by-step explanation:

\frac{sinB}{b}=\frac{sinC}{c}\\\\sinB=\frac{sinC}{c}(b)\\\\B=sin^{-1}(\frac{sin(29)}{9}(18))\\\\B=75.8=76

Therefore, m∠B = 76°.

Emanuel works as a car salesman. He makes $13 an hour plus a commission of 5% on all cars he sells. Last month he worked 40 hour
gtnhenbr [62]

Solution: Emanuel earns $13 per hour. Also he earns a commission of 5% on all cars he sells.

Number of hours Emanuel worked last month = 40 hours

He sold cars worth $120,000.

Therefore, the total earning of Emanuel is:

13 \times 40 + 5\% of 120,000

520 + \frac{5}{100} \times 120,000

520+6000

6520

Hence, last month Emanuel made $6520, including his hourly pay and commissions.

How do I solve this?
beks73 [17]
Distribute the exponent power of 2 to each term:
[2² * (√(3x⁵))² - 2² * (√y)²]

Now simplify. Placing a square root to the power of 2 just cancels each other out so you're left with:
[4(3x⁵) - 4y]

Simplify again for your answer:
12x⁵ - 4y

Lisa [10]

Answer:

Below.

Step-by-step explanation:

Number is different to the other 2. Its value is +4 because negative 2 squared = + 4.

The other 2 have negative values and -2 = -(2) so they have the same value, -4.
