At their last babysitting gig, Zainab made $44 for 8 hours of work and Keziah made $47.25 in 9 hours. Each girl charges a different hourly rate. For a 10 hour job, which girl will make more money? How much more?

Answers

Answers:

Zainab made more moneyShe made $2.50 more

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

Explanation:

To find the hourly rate, we divide the money made over the number of hours.

Zainab's hourly rate = 44/8 = $5.50 per hourKeziah's hourly rate = 47.25/9 = $5.25 per hour

Then we'll multiply each of these results by 10 to figure out how much they made over the 10 hours

Zainab: 5.50*10 = 55 dollarsKeziah: 5.25*10 = 52.50 dollars

We see that Zainab made more money and she made 55-52.5 = 2.50 dollars more.

If 7m - 3 = 53. What is the value of 11m + 2?

Answers

Answer:

90.

Step-by-step explanation:

7m - 3 = 53

m would be 8 because 56 - 3 = 53.

11m + 2 equals 90 because 11 times 8 (8 is m) is 88, which added by two is 90.

Every integer is a rational number.
True or false

Answers

Answer:

Every integer is a rational number. The statement is true. An integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero.

For example, lets use the integer, -5.

If it was rational number it would need to be either a decimal or fraction.

So -5 is not a rational number and is an integer.

If the number was 0.5 or 1/5, the number would have been rational.

Inconclusion your statement is true.

what is the perimeter of the larger rectangle?

Answers

Answer:

30 meters

Step-by-step explanation:

Perimeter smaller rectangle: 2(x+1)+2x = 2x+2+2x

= 4x+2

Perimeter larger rectangle: 2(4x-5)+2(3x-1) = 8x-10+6x-2

= 14x -12

2(4x+2)+2 = 14x-12

8x+4+2 = 14x - 12

8x + 6 = 14x - 12

6 + 12 = 14x - 8x

18 = 6x

x = 3

14*3-12 = 30 meters

Answers

Step-by-step explanation:

x = the area in black

each triangle have area = 80

the area of the 3 triangles without combining them = 80 × 3 = 240

the total area = 210

the total area in the figure = 3 triangles area - 2x

because we have calculated 1 black area not the three of them so we need to add its area once and get rid of the others by subtracting them from the sum of the 3 triangles area

240 - 2x = 210

2x = 30

x = 15

hope that helps

240-2x=210
2x=30
x=15

800 divided by 39 please show steps

Answers

Answer:

20.51282

Step-by-step explanation:

1. Starting by the smallest number that can be divided. 80÷39 equals to 2.

2. Now we write 2 in the answer line.

3. Multiply the result by 39. That makes us 78.

4. Now we write 78 under 800.

5. Subtract the numbers (80-78) and now we have 2.

6. Bring 0 next to our substracted number (2) so that will make it 20.

7. Divide the subtracted number with our initial value (39). That will make us a decimal number (0.512) but we will note the 0 except if you want to make it detailed then note 20.51282

8. Add the 0 next to the 2 that we writed in the start above.

9. Write the remainder (20) next to the quotient.

10. The result is 20 or to be exact 20.51282 and we have a remainder of 20.

1/2x +1/2=x+1 how to solve

Answers

hope it helps youuuuuu

Answer:

x=-1

Step-by-step explanation:

1/2x +1/2=x+1

Subtract 1/2x from each side

1/2x-1/2x +1/2=x-1/2x+1

1/2 = 1/2x +1

Subtract 1 from each side

1/2 -1 = 1/2x +1-1

-1/2 = 1/2x

Multiply each side by 2

2 * (-1/2) = 1/2 x*2

-1 =x
