Answer:

∠A = 94º

∠C = 86º

Step-by-step explanation:

You just need to know that the sum of the two angles in a parallelogram must be equal to 180º. Let's make an equation.

(5y-3)+(3y+27)=180

Solve;

5y-3+3y+27=180

Combine like terms;

8y+24=180

Subtract 24

8y=180-24

8y=156

Divide by 8

y=\frac{156}{8}

Simplify.

y=\frac{39}{2}

Replace;

∠A = 5y-3

5(\frac{39}{2})-3\\ \frac{195}{2}-3\\ \frac{195-2*3}{2}\\

\frac{195-6}{2}

\frac{189}{2} =94.5≅ 94

----------------------------------------------------------------------------------------------

∠C =

3y+27\\3(\frac{39}{2})+27

\frac{117}{2}+27

\frac{117+27*2}{2}

\frac{117+54}{2}

\frac{171}{2}=85.5≅86

The price of a coat increased from $78 to $92. What is the price increase percentage?
svetlana [45]

Answer:

18%

Step-by-step explanation:

Percent change can be found using the following formula:

\frac{original-new}{original}*100

Original represents the initial cost where new represents the new cost.  We multiply the answer by 100 to get the percentage:

\frac{92-78}{78}*100 = 18%

28 prime factorization
sineoko [7]

Answer:

2 x 2 x 7, or 2^2 x 7

Step-by-step explanation:

Let us use prime factorization to find the prime numbers that make up 28:

28 = 2 x 14            

2 is a prime number, 14 is not, so we have our first prime, 2.

14 = 2 x 7      

We then further break the number down into two prime numbers, 2 and 7. Since 2 and 7 are prime and we can't break them down any further our answer is 2 x 2 x 7, or 2^2 x 7.

To find how many minutes of talk time is available per dolla, you have to divide 160 (number of minutes) by 40 (cost) 160/40 = 4 Therefore, it's 4 minutes per dollar
