The area of a rectangular sheet of metal is 135 square inches. The perimeter is 48 inches. What are the dimensions of the sheet?

Answers

Answer 1

Answer:  The length is 15 inches and breadth is 9 inches

Step-by-step explanation:

Given : Area of rectangular sheet = 135 square inches

Perimeter of rectangular sheet = 48 square inches

Now Area of rectangular sheet = [tex]Length\times Breadth[/tex] =  135 square inches

perimeter of rectangular sheet = [tex]2\times (Length+Breadth)[/tex] = 48 square inches

Thus [tex](Length+Breadth)[/tex] = 24 square inches

Thus Length = 15 inches

Breadth = 9 inches

Step-by-step explanation:

Step 1: Define

f(x) = 5x - 2

f(6) is x = 6

Step 2: Evaluate

Substitute in x [Function]:                                                                                f(6) = 5(6) - 2Multiplication:                                                                                                    f(6) = 30 - 2Subtraction:                                                                                                       f(6) = 28
Answer:  28

=========================================================

Explanation:

Everywhere you see an x, replace it with 6

f(x) = 5x - 2

f(6) = 5*6 - 2

f(6) = 30 - 2

f(6) = 28

Remember that 5x is the same as 5*x or "5 times x". So that's why 5x turned into 5*6 after replacing x with 6. After every x is replaced, you follow the order of operations PEMDAS to simplify.

Mary always saved 45% of his salary. When his salary decreased by 20% in April, his savings decreased by $180.
How much was Mary’s salary before the decease?

Answers

Answer:

Step-by-step explanation:

Answer:

Is Mary a guy?  :|  

Step-by-step explanation:

I did this by just a good guess  , not really the right way

2000*.45=900  ( 900 is the old savings)

2000*.2 =400   ( how much her salary went down by )

2000-400=1600 ( new salary )

1600*.45 = 720    ( 45% of new salary is new savings

900-720=180      ( change in savings is 180 , the amount the question asks for)

Mary's old salary was 2,000

The ratio of boys to girls in a class is 5:7. There are 36 students in the
class. How many more girls than boys are there?

Answers

Answer: number of girls = 21 & number of boys = 15

                     21 - 15 = 6 ( the difference is 6 )

Step-by-step explanation:

Answer:

add the ratios together. this gives 5+7 which is 12. divide 36 by 12, this gives 3. this tells us it's three students for every value of the ratio, so the ratio is 5(3):7(3). it becomes 15 boys to 21 girls. to find out how many more girls, we subtract 15 from 21. our answer is 6.

Number of Solutions

Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.
