(Please show work!)

Answer:

the answer is D

Step-by-step explanation:

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.

Step-by-step explanation:

60n=180

n=3

180(2-3)

360-540=-180

3-5/-2-(-1)

-2/-1 =

2

Answer:

2

Step-by-step explanation:

The slope is rise over run,

the equation for finding it is,

[tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

given the points

-2, 3

-1, 5

[tex]x_{1}[/tex] = -2

[tex]x_{2}[/tex] = -1

[tex]y_{1}[/tex] = 3

[tex]y_{2}[/tex] = 5

substitute in

[tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

=[tex]\frac{(5) - (3)}{ (-1) - (-2)}[/tex]

simplify,

[tex]\frac{2}{1}[/tex]

= 2

Answer: Option B - 3 1/2

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.

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

Answer:

y=-2x+5

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

how do you know if an equation has infinite solutions?

if the equation ends with a true statement, like 3=3, then you know it has sinfinite solutions. in this situation x=x

C:

3(2x+1)=6x+3

(multiply 3 by (2x+1))

6x+3=6x+3

(subtract 6x-3 from both sides)

0=0

Answer:

(3x + 7) -4 = 17

Answer:

Cost per gusset = 4

Step-by-step explanation:

Given:

Cost for 12 people party = $48

Cost for 22 people party = $88

Find:

Cost per gusset

Computation:

Cost per gusset = 48 / 12

Cost per gusset = 4

Cost per gusset = 88 / 22

Cost per gusset = 4

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

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

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

Answer:

I believe it is 5/7

Step-by-step explanation:

y2-y1 over x2-x1 which is 6-1 over 4- (-3) ----> 6-1=5, 4+3=7 -----> 5/7

Answer:

The slope should be 5/7.

Step-by-step explanation:

You take the 6 and subtract from 1

And you take the 4 and subtract from -3

6-1/4- -3= 6-1/4+3=5/7
