A=xy
If there is 10% increase in x then,
New value of x = x + 10%of x =1.1x
similarly for y
New value of y after increase= 1.1 y
New value of A after increase in x and y = 1 .1x × 1.1 y= 1.21xy
now
increase amount in A= New value of A - old value of A
=1.21xy - xy= 0.21xy
percentage increase in A= (0.21xy÷xy )× 100= 21%

Write a decimal that is less than 6.73

faust18 [17]

4.2 would be an example, but there are many more. Honestly, it wouldn't matter as long as it was less than 6.73.

Follow the steps above and find c, the total of the payments, and the monthly payment. Choose the right answers.

saveliy_v [14]

To the nearest penny, c = $6,252.50

Total of payments = amount financed + c = $26,752.50

Total of payments ÷ number of payments = monthly payment = $445.88

Find the distance between -2 1/2 and -5 3/4 on a number line

Elena-2011 [213]

Answer:

13/4

Step-by-step explanation:

Convert these numbers to a mixed fraction.

-5 3/4 => -23/4

-2 1/2 => -5/2

Make them have a common denominator

-5/2 => -10/4

-23/4 can stay the same.

To find the distance between the two numbers, subtract the lesser value from the greater value.

-23/4 is <u>less</u> than -10/4.

(-10 - (-23)) /4

= 13/4

Therefore the distance between -2 1/2 and -5 3/4 on a number line is 13/4.
