Every day kianna practices softball and piano each day she practices for 2 hours if after 7 days she practiced both softball and piano for a total of 24.5 hours how many hours per day did kianna ptactice piano

Answers

Answer 1

Answer: 1.5 hours

Step-by-step explanation:

Softball was practiced for 2 hours each day.

After 7 days she must have practiced it for;

= 7 * 2

= 14 hours

She practiced both piano and softball for a total of 24.5 hours. She therefore practiced piano for;

= 24.5 - 14

= 10.5 hours

If in 7 days she practiced piano for 10.5 hours, everyday she must have practiced piano for;

= 10.5/7

= 1.5 hours

A company paid $48 for 2 cases of printer paper./Each case contained 12 packages of paper./ Next month the company's office manager needs to order 180 packages of the same paper./ If the price per package does not change,/ what would be the total cost of next month's order?

Answers

Answer:

$360

Step-by-step explanation:

Calculation for what would be the total cost of next month's order

First step is to calculate how much they paid per the two cases of printer papers

Two cases of printer paper=$48 /2

Two cases of printer paper=$24 per case

Second step is to calculate the cost of each package of printer paper

Cost of each package of printer paper=$24/12 packages of paper

Cost of each package of printer paper=$2

Last step is to calculate the total cost of next month's order

Total cost=180 packages*$2

Total cost=$360

Therefore what would be the total cost of next month's order is $360

A square parking lot has an area of 12,996 square yards. a. What is the length of one side of the parking lot? b. How many yards of fence will it take to enclose the entire parking lot?

Answers

Answer:

114 yards

456 yards

Step-by-step explanation:

Given that:

Area of square parking lot = 12,996 square yards

The lenght of one side of the parking lot :

Area of a square = a² ; a = side length

Hence ;

12996 = a²

√12996 = a

114 = a

Hence, length of one side = 114 yards

Yards of fence needed to enclose parking lot :

Perimeter of a square = 4a ; a = side length

Perimeter = 4(114)

Perimeter = 456 yards

Find the slope of the line that passes through (8,4) and (6,5)

Answers

Answer:

-1/2

Step-by-step explanation:

The equation for slope is y2 - y1 and x2 - x1. So you do 5(y2) - 4 (y1) which is 1. And 6(x2) - 8(x1) which is -2. Put 1 as the numerator and -2 as the denominator as you got -1/2. The fraction is negative because the -2 made it that way

Hello does anyone know how to figure this out? - 3(4 + x) = x + 6

Answers

Answer:

-4.5

Step-by-step explanation:

-12-3x=x+6

-4x=18

x=-4.5

Answer:

-4.5=x

Step-by-step explanation:

First you would distribute the -3 to the 4 and x inside the parentheses

It would be -3 x 4= -12

Then  -3 x X= -3x

So your equation would now be -12+ -3x = x + 6

Now you add  3x to the -3x to cancel it out and then add it to the x

So your equation now looks like -12=4x +6

Then you subtract 6 from the 6 to cancel it out and add it to the -12

Now your equation looks like -18=4x

Then you divide 4 from the 4x to cancel it out and then divide 4 from the -18

Finally you have  -4.5=x

I'm unsure if this is correct but hopefully this helps :)

Answer:

x= 30

Step-by-step explanation:

3x + 50 = 140

3x = 140 -50

3x = 90

x = 90/3

x = 30

Answer:

x = 30

Step-by-step explanation:

The given angles are vertical and congruent , then

3x + 50 = 140 ( subtract 50 from both sides )

3x = 90 ( divide both sides by 3 )

x = 30
