Answer:

cos(C)

Step-by-step explanation:

Recall that the sine ratio is opposite over hypotenuse.

$\sin(A) = \frac{BC}{AC}$

Also the cosine ratio is adjacent over hypotenuse.

$\cos(C) = \frac{BC}{AC}$

The tangent ratio does not come close because it doesn't involve the Hypotenuse.

$\therefore \sin(A)=\cos(C)$

Answer:

B. -3d + 47.25

Step-by-step explanation:

Each of them has $15.75

Each spent $d

Amount each still has = 15.75 - d

Therefore, total amount the 3 of them has = 3(15.75 - d) = 3*15.75 - 3*d

= 47.25 - 3d

Which is also am equivalent of -3d + 47.25

You go to Home Depot to buy some materials for a project. Your total bill for materials only was $45.90. You go to the check out

IrinaVladis [17]

Answer:

$34.20

Step-by-step explanation:

First, find the cost with tax

You are paying 7.2% tax, but you are also paying for 100% of the bill

100%+7.2%=107.2%

So, you are really paying for 107.2% of the bill

Convert 107.2% to a decimal by dividing by 100 or moving the decimal 2 spaces to the right

107.2/100=1.072

Multiply the decimal by the cost of the bill

1.072*45.90=49.2048

But, we also have a coupon for $15 off

Subtract 15 from the cost with tax

49.2048-15=34.2048

Round to the nearest cent/hundreth

$34.20

Hope this helps! :)

Please help u have to factor

enot [183]

Both terms have a $-m^2n$ in common, so we can pull it out. The factored form will be $-m^2n$ times whatever is left after pulling it out.

In the first term, we will have just 8 left since everything else in the term is factored out.

The second term has a $7m^4n^3$ left. Notice that both of these terms no longer have a negative sign since the negative was factored out.

The answer is $(-m^2n)(8+7m^4n^3)$

Translate this phrase into an algebraic expression: Six more than the product of 22 and Jenny's height. Use the variable m to re

Akimi4 [234]

6 + 22m
More = additionProduct = the number that is the result of multiplication6 more (+) than the product (result of) 22*Jenny's Height

If Jenny's height is 5.5 ft:6 + 22*5.5 = 6 + 121 = 127
Hope this helps clear things up a bit.
