Answer:

sinE = \frac{3}{5}

Step-by-step explanation:

To find sinE we require DF

Using Pythagoras' identity in the right triangle

DF² = EF² - DE² = 10² - 8² = 100 - 64 = 36 ( take square root of both sides )

DF = \sqrt{36} = 6

Then

sinE = \frac{opposite}{hypotenuse} = \frac{DF}{EF} = \frac{6}{10} = \frac{3}{5}

We want to get x by itself
First we will multiply both sides by 6 to cancel out the 6 on the left
5x = 120
We then divide by 5 on both sides to get x by itself

First, you need to find the total amount they discounted.

3.66 X 3= $10.97

Since they took off that much, you need to add that to the total cost, which was 62. 31

62.31 + 10.97= $73.29

Finally, to find how much each individual shirt cost, you divided it by 3.

73.29 / 3= $24. 43

The answer is C

Answer:

B

Step-by-step explanation:

In A, it says that 9s +7c can be lower or equal to 160. This is wrong.

In C, it says that 9s +7c can only be higher than 160, when the question says at least, which means it can also be equal to 160, making it wrong.

In D, it says that 9s +7c can be lower or equal to 20. This is wrong.

Through elimination, only B can be right.

Approximately 1.9 million primes of a certain type are reported to the place every year

I suspect that you might mean 'crimes' and 'police'.  If that's the case,
then what we have here is a sentence that has not been proofread
for errors, and doesn't ask any question. I'm not going to worry about it.
