Rosemary is driving to Chicago, and she is 84 miles away. She wants to arrive in 1.5 hours. What rate of speed will she have to maintain to arrive in that time?
Group of answer choices

Rosemary needs to maintain 126 mph.

Rosemary needs to maintain 65 mph.

Rosemary needs to maintain 56 mph.

Answers

Answer:

56 mph

Step-by-step explanation:

Process of elimination. 126 mph is much too high because it's more than the distance and they will arrive too early. 65 + 65 ÷ 2 = 97.5, that's more than 84 miles. The reason we divide by 2 is because of the .5. Now all we have is 56 mph. To check, 56 + 56 ÷ 2 = 84

Answer:

56

84 / 1.5 = 56

Lily likes to collect records. Last year she had 10 records in her collection. Now she has 13 records. What is the percent increase of her collection?

Answers

Answer:

We know if we put the number of records in the end ÷ the number of records previously, we can get the percentage change.

13/10 = 1.3

1.3 - 1 (Because we want to find the increase, not the amount of percentage this is to that)

a. How high above the water is the roadway in meters? Round to the nearest hundredth.

The roadway is about ____ meters above the water.



Question 2
b. The bridge has a length of 26,372 feet. What is the length in kilometers? Round to the nearest hundredth.

The length of the bridge is about ____ kilometers.

Answers

a: 60.66 m
b:8.04 km

The roadway is about 60.66 meters above the water.

The length of the bridge is about 8.04 kilometers.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 km = 1000 m

We have,

The length of the roadway above the water = 199 ft

1 ft = 0.3048 m

Multiply 199 on both sides.

199 ft = 60.66 m

The bridge has a length of 26,372 feet.

1 ft = 0.0003048

Multiply 26372 on both sides.

26372 ft = 26372 x 0.0003048

26372 ft = 8.04 km

Thus,

The roadway in meters is about 60.66 meters above the water.

The length of the bridge in km is about 8.04 kilometers.

Suppose the new actual number of pizzas sold today was 60. The original previous day sold was 65. Describe the number of pizzas sold as a percent increase or decrease (aka Percent of Change), rounded to the nearest hundredth.

Answers

Answer: 1) Pizzeria must sell 78 pizzas for receiving the bonus.
2) The number of pizzas sold is decreased by Approximately 7.69 %.
Step-by-step explanation:
1) The number of pizza sold yesterday = 65,
The target for receiving the bonus = 20% more than the number of pizza sold yesterday
= 20% more than 65,
= 65 + 20% of 65 ( 1% = 0.01 ⇒ 20% = 0.2 )
= 65 + 0.2 × 65
= 65 + 13 = 78.
Hence, they must sell 78 pizzas for receiving the bonus.
2) If the actual number of pizza sold today = 60
⇒ Total reduction in the number of pizza = 65 - 60
= 5
Thus, the percentage decrease in the number of pizza

3,000 pounds of sand is usede to fill sandboxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes. how much sand can be put in each of the smaller sandboxes?

Answers

500pounds because 2000 (the left over sand after you fill the big box) divided by 4(smaller sandboxes) is 500

The amount of sand that can be put in each of the smaller sandboxes is 500 pounds.

What is division?

Division is breaking a number up into an equal number of parts.

Given that, 3,000 pounds of sand is used to fill sandboxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes.

Amount left after filling the larger box = 3000-1000 = 2000 pounds

To find the equal amount of sand to be filled in 4 smaller boxes, we will divide the amount left to the number of boxes.

= 2000/4

= 500

Hence, The amount of sand that can be put in each of the smaller sandboxes is 500 pounds.
