daniel earns extra money as a lifeguard he earns 37 dollars for 4 hours and 64.75 for 7 hours. the relationship between his earnings and the time worked is proportional true or false?​

Answers

Answer: Yes, it is proportional.

Step-by-step explanation:

Find the amount Daniel earns each hour.

Divide the amount of money by the number of hours to find each earnings per hour.

Life guard:  $37 for 4 hours.

37/4 = 9.25

64.75/ 7 = 9.25

Since Daniel receives the same amount of money per hour which is $9.25 per hour, then the relationship is proportional.

Answers

Answer: y=−12x+72

Add -6x to both sides.

You should get: 1/2y - 36 = -6x

Add 36 to both sides.  

1/2y = 36 - 6x

Divide both sides by 1/2.

Which gives you

y = -12x +72

Sheila has 11 1 2 pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 1 1 4 pounds. How many containers does she need?

Answers

Answer:

9 containers

Step-by-step explanation:

Given

Total pounds of potato salad = 11 1/2 pounds

If one container holds 1 1/4 pounds:

The number of container that 11 1/2 pounds can hold is expressed as:

Number of container = Total pounds/volume of one container

Number of container = 11 1/2 ÷ 1 1/4

Convert to improper fraction

Number of container = 23/2 ÷ 5/4

Number of container = 23/2 × 4/5

Number of container = 92/10

Number of container = 9.2

Therefore she will need 9 containers

Step-by-step explanation:

Using the graph they give you on your problem, you can see that they split the fourths into eighths for you. To find how much sauce Alfredo has, you can count the little squares at the bottom up to 7. Then, you check where that is relative to the top squares. When you finish counting, you will see you have passed 3 of the 1/4 size boxes and you are halfway through the last 1/4 size box. Therefore, Alfredo can make 3 and 1/2 servings.

Salam walks along a path surrounding a circular pond. The paths radius is 150 meters. Salam walks 75 meters per minute. About how long does it take Salam to walk around the path once.

Answers

Answer:

The time it takes Salam to walk around the path once is 12 minutes 34 seconds

Step-by-step explanation:

Given;

radius of the circular pond, r = 150 m

speed of Salam, v = 75 m/min

A single distance round the circular path is given by;

d = 2πr

d = 2π(150)

d = 942.6 m

Time it takes Salam to walk around the path once, is given by;

time = distance / speed

time = 942.6 / 75

time = 12.568 minutes

time = 12 minutes 34 seconds

Therefore, the time it takes Salam to walk around the path once is 12 minutes 34 seconds

The value of x in terms of b is   x = -3/b

The value of x when b is 3 is    x = -1

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

Work Shown:

Let's isolate x

-2(bx - 5) = 16

bx - 5 = 16/(-2) ... dividing both sides by -2

bx - 5 = -8

bx = -8+5 ... adding 5 to both sides

bx = -3

x = -3/b ... dividing both sides by b

That wraps up the first part.

-----------

To answer the second part, we plug in b = 3 to get

x = -3/b

x = -3/3

x = -1
