The percent equivalent to 1 / 4 = 25 %.
The percent equivalent to 3 / 4 = 75 %.
25 % x 3 = 75 % ( correct )

PLEASE HELP!!! I CANT DO THIS

Answer:

∠WVU = 67°

Step-by-step explanation:

∠WVU = 1/2(arc WV)

8x + 11 = 1/2(15 + 17x)

8x + 11 = 7.5 + 8.5x

subtract 7.5 and 8x from each side of the equation:

0.5x = 3.5

multiply both sides by 2:

x = 7

∠WVU = 8(7) + 11 = 67°

proof:

arc WV = 15 + 17(7) = 134° which is 2 x 67°

How to do this math exercise 4x-2y=60<br> 4x-3y=26

igomit [66]

4x -2y = 60
4x -3y = 26
(-) (+) (-)
__________
1y = 34
y = 34

To find x
4x -2y = 60
4x -(2)(34) = 60
4x -68 = 60
4x = 60 + 68
4x = 128
x = 32

Answer:
x=32 ; y=34

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