i need help on the last part!

Answers

Answer:

0; (0, 0); 144; (3, 144)

Step-by-step explanation:

Y = distance (m)

X = time (hr)

X = 48x

If a car travels for 0 hours, it will travel __ mile(s).

y = 48x

Plug in 0 hours for x (time in hours)

y = 48(0)

Any number mutliplied by 0 equals 0

y = 0

If a car travels for 0 hours, it will travel 0 miles. This means it will pass through the point (0, 0).

(0, 0) limits our options to graphs B and D

Car travels 144 miles in 3 hours

To find how many miles it travels in 1 hour, divide 144 miles by 3 hours

144 ÷ 3 = 48

In 1 hour, a car travels 48 miles

If 48 × 3 = 144, then 48 × 4 = ?

48 × 4 = 192

When looking at graph D, there are 4 lines above 0

Counting by 48, it perfectly fits 192 by the fourth line

From (0, 0), if we move 3 units to the right we can find the third vertical line intersecting

Since the lines are counted by 48 and we are looking at the third line: 48 × 3 = 144

Use the slope to move 3 units to the right of the origin and 144 unit(s) up to the find the point (3, 144) that can be used to graph the relationship

In 2 hours they rest for 16 minutes.

So first we should work out how long they rested for in 1 hour.

We do this by simply doing 16 (minutes of rest) divided by 2 (hours of dancing):

16 / 2 = 8

In one hour of dancing they rest for 8 minutes.

Now to work out how long they rested in 3 hours, we simply do 3 (hours of dancing) x 8 (minutes of rest per hour):

3 x 8 = 24

The couple spent 24 minutes resting in 3 hours of dancing.

Answer:

The couple rested for 24 mins in 1 hour

The unit rate is 8

Answers

Answer: I believe it’s D

Step-by-step explanation:

Answer:

I believe the correct answer would be d= 4h

This is because D is represented as dress and H is hour. So if it takes Nina to make a dress in 4 hours the obvious expression would be per every dress it took 4 hours or in other words d= 4h.

Mauricio bought 6.75 yards of fabric for a total of $47.50
About how much was the cost per yard? Explain why your
answer is reasonable. ( brainliest included for correct answer)​

Answers

Answer:

$7.04

Step-by-step explanation:

47.50/6.75 which is about $7.04

My answer is reasonable because 47.50 is close to 49 and 6.75 is close to 7 and 49/7 is 7,  which is about 7.04.

Hope this helps :D

Answer:

About $7.04 / yard.

Step-by-step explanation:

We divide the total cost by the length of fabric.

Cost per yard = 47.50 / 6.75

= 7.037

= $7.04 to the nearest cent.

This is reasonable  because  6.75 yards is close to 7 yards and 7 * $7 = $49.
