Mathematics
1 answer:
kkurt [141]3 years ago

Answer:

x=10°

y = 12°

Step-by-step explanation:

<TSV = 5x + 4x = 90°

=> 9x = 90°

Divide by 9,

x = 10°

<RSU = 10y + 10° + 5x = 180°

=> 10y + 10° + 5*10° = 180°

=> 10y + 10° + 50° = 180°

=> 10y + 60° = 180°

Subtract 60° on both sides,

10y = 180° - 60° = 120°

Divide by 10,

y = 120° / 10 = 12°

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. The length of each
aleksley [76]

Answer:

15 inches

Step-by-step explanation:

Suppose length of original square is L inches.

Now, to form a new square the length increases by 2.5 inches

So, new length=L+2.5 inches

Given that, perimeter of new square =70 inches.

Formula:-

        Perimeter=4*length of square

Therefore 70=4*(L+2.5)

                   70 =4 L+10

                   4 L=60

                  L=15 inches

Please explain how you got the answers also please. Thank you :)
Umnica [9.8K]

Answer:

x = -2 —> y = 4

x= 0 —> y = 1

x= 3 —> y = 1/8

Step-by-step explanation:

<h3>X= –2</h3>

y = ( \frac{1}{2} ) ^{x}  \\ y = ( \frac{1}{2} ) ^{ - 2}  =(  \frac{2}{1} ) ^{2}  =  {2}^{2}  = 4

<h3>X= 0</h3>

y = ( \frac{1}{2} ) ^{x}  \\ y = ( \frac{1}{2} ) ^{ 0}  =1

<h3>X= 3</h3>

y = ( \frac{1}{2} ) ^{x}  \\ y = ( \frac{1}{2} ) ^{ 3}  =  \frac{ {1}^{3} }{ {2}^{3} } =  \frac{1}{8}

I hope I helped you^_^

I really need a quick answer! What is 8y + 12?
astra-53 [7]

Answer:

24

Step-by-step explanation:

To figure out what the value of y is, we must isolate the variable. To do this, we need to use the division property of equality which says that when you divide on one side of the equal sign, you must also divide on the other side.

8y/8 = y

12/8 = 1.5

This tells us the value of y, so next we have to apply this into the problem

8(1.5) = 12

12 + 12 = 24

24 is your answer
