Answer:

The answer would be B

Step-by-step explanation:

You would have to multiply 27 x 9 to get a total of 243. Then, You can subtract 748 - 243 (But since that's not an option, B would be the answer because it's basically the same total you get.)

Hope it helps! :D

Solve the triangle<br> a <br> b <br> c<br> d
Mekhanik [1.2K]

Answer:

B

Step-by-step explanation:

Use the Law of Cosines to find the measure of segment c:

c=\sqrt{a^2+b^2-2ab*cos(C)}\\\\c=\sqrt{12^2+13^2-2(12)(13)*cos(134)}\\\\c=\sqrt{313-312cos(134)}\\\\c=\sqrt{313-312(-.6946583705)}\\\\c=\sqrt{313-(-216.7334116)}\\\\c=\sqrt{313+216.7334116}\\\\c=\sqrt{529.7334116}\\

c ≈ 23.01593821 km ≈ 23 km

Since c = 23 km, our only options are choices B and D. Now, let's find the measure of angle A to confirm. To do this we will use the Law of Sines:

\frac{sin(A)}{a} =\frac{sin(C)}{c} \\\\\frac{sin(A)}{12}=\frac{sin(134)}{23.01593821}\\\\sin(A)=12(\frac{sin(134)}{23.01593821})\\\\A=sin^{-1}[12(\frac{sin(134)}{23.01593821})]\\\\

A ≈ 22.02726885° ≈ 22°

Since the measure of c = 23 km and the measure of angle A = 22°, the answer must be choice B.

sveta [45]
Your problem is missing the units after the numbers. It could be 4 cents and 32 cents, 4 dollars and 32 dollars, 4 cents and 32 dollars, 4 dollars and 32 cents, etc. 

Assuming both are in dollars:

32 / 4 = 8

Deshaun can buy 8 pounds of candy.

Drop of water = 75,000

Find:

How many gallons of water are equivalent

Computation:

Amount of water are equivalent = Drop of water / Parts per billion

Amount of water are equivalent = 75,000 / 5
