Answer:

Step-by-step explanation:

Amanda's unit rate would be

s=50m

while Mary's is

s=60m

60-50 is 10, meaning the answer would be D.

Mary saves $10 more than Amanda every month.

Hope this helps! :)

Hi there!

We can find an equation that models Amanda's savings using the equation:

y = km, where:

k = rise / run (Amount/months)

Plug in a set of values from the table:

k = 100/2 = 50

y = 50m

We know that Mary saves y = 60m dollars a month, so we can determine the correct comparison by plugging in a value of 1 month into both equations:

Amanda:

y = 50(1) = $50

Mary:

y = 60(1) = $60

The difference between Mary's and Amanda's savings is $60 - $50 = $10, so each month, Mary saves $10 more than Amanda.

The correct answer is D.

Answer:

$\large \boxed{\sf \text{The rate of the boat is } 53 \ km/h \text{, the rate of the current is }8\ km/h \ \ }$

Step-by-step explanation:

Hello, let's note v the rate of the boat and r the rate of the current. We can write the following

$\dfrac{135}{v-r}=3=\dfrac{183}{v+r}$

It means that

$135(v+r)=183(v-r)\\\\135 v + 135r=183v-183r\\\\\text{ *** We regroup the terms in v on the right and the ones in r to the left***}\\\\(135+183)r=(183-135)v\\\\318r=48v\\\\\text{ *** We divide by 48 both sides ***}\\\\\boxed{v = \dfrac{318}{48} \cdot r= \dfrac{159}{24} \cdot r}$

But we can as well use the second equation:

$3(v+r)=183\\\\v+r=\dfrac{183}{3}=61\\\\\dfrac{159}{24}r+r=61\\\\\dfrac{159+24}{24}r=61\\\\\boxed{r = \dfrac{61*24}{183}=8}$

and then

$\boxed{v=\dfrac{159*8}{24}=53}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Find an angle between 0 and 2pi coterminal with 35pi/6

Leona [35]

For the answer to this question, we have to solve it step by step.
We have to divide both sides by 35.
35π = 35(180)
 35 35

= 1050°

1050° - 360° - 360° = 330°
If you would graph it, it would be -30 ° and it is coterminal

I hope my answer helped you somehow

Suppose you are facing north, each time you turn, you are going to turn 90 degrees. If you turn 2 times to the right, 1 time to

zysi [14]

Answer:

East

Step-by-step explanation:

Starting position = North

Condition = each time you turn, you are going to turn 90 degrees

Using the image attached as a guide;

If you turn 2 times to the right

- Turning the first time to the right changes the direction to East

- Turning the second time to the right changes the direction to South

1 time to the left

- Turning once to the left changes the direction to East

3 times to the right

- Turning the first time to the right changes the direction to South

- Turning the second time to the right changes the direction to West

- Turning the second time to the right changes the direction to North

2 times to the right

- Turning the first time to the right changes the direction to East

- Turning the second time to the right changes the direction to South

1 time to the left

- Turning once to the left changes the direction to East

Darren wants to build a regulation size pool table that is 9 feet in length. The plans he ordered are 18 x 36”. What is the scal

-BARSIC- [3]

Answer:

Width and length of the plan is 18 inches and 36 inches. The required length of the table is 9 feet, which is 9 * 12 = 108 inches

So scale factor = $\frac{Required length of the table}{Length of the plan}$ = $\frac{108}{36}$ = 3

The answer is 3
