Answer:

A.) 4h : $36

Step-by-step explanation:

Why it's right: they equal the same thing

5/45 = 1/9

4/36 = 1/9

Why it's wrong: similar, but backwards

54/6 = 9

Just plain wrong:

4/50 = 2/25

63/9 = 7

Triangle P R Q is shown. Angle R P Q is 39 degrees. The length of P R is 6, the length of R Q is p, and the length of P Q is 8.

KATRIN_1 [288]

According to law of cosines the length of RQ can be written as $p^{2} =6^{2} +8^{2} -2*6*8cos(39)$ .

Given the length PR is 6 , the length of RQ is p, the length of PQ is 8 and the angle RPQ is 39 degrees.

A length of the triangle can be written as according to law of cosines if sides are given and one angle is $a^{2} =b^{2} +c^{2} -2bccos(A)$

We have to just put the values in the above equation.

as $p^{2} =6^{2} +8^{2} -2*6*8cos(39)$ .

p is the side opposite to angle given , the length of other sides are 6 and 8 and angle is 39 degrees.

Hence the side can be written as according to law of cosines if the angle is 39 degrees is as $p^{2} =6^{2} +8^{2} -2*6*8cos(39)$ .

A quarter is worth of a dollar. Haley needs to exchange dollar bills to get quarters to do her laundry in coin washers and dryer

Ira Lisetskai [31]

Answer:

52 quarters

Step-by-step explanation:

-We know that a quarter dollar is equivalent to $0.25

$\$1=4 \ Quarters$

-Given that Haley has $13, we multiply this amount by 4 since $1 has 4 quarters to obtain the number of quarters:

$Q=13\times 4\\\\=52$

Hence, Hayley will get 52 quarters.

If f(x) = 4x ^ 2 and g(x) = x + 1 , find (fg)(x) ).

Irina-Kira [14]

Answer:

$\boxed{\sf \ C \ is \ the \ correct \ answer \ ! \ }$

Step-by-step explanation:

fog(x)=f(g(x))

so it comes

$f(g(x))=f(x+1)=4(x+1)^2$

<u>so C is the correct answer</u>
