he Sanchez family drove 132 miles in 3 hours before lunch. Then they drove 240 miles in 5 hours after lunch. What was their average speed for the day? A. 54.5 mi/h B. 46.5 mi/h C. 46 mi/h D. 54 mi/h

Answers

Answer 1

Answer: the answer is b. 46.5

Hope this helped :)

Answer 2

Answer: Average speed = total distance/total time.

Total distance = 132 + 240 = 372
Total time = 3 + 5 = 8

372 / 8 = 46.5 mph
Therefore B is the correct answer.

Which measure is of an angle that is coterminal with a 95° angle?

Answers

Find coterminal angles Ac to a given angle A.

What are coterminal angles?

If you graph angles x = 30o and y = - 330o in standard position, these angles will have the same terminal side. See figure below.

Coterminal angles Ac to angle A may be obtained by adding or subtracting k*360 degrees or k* (2 Pi). Hence

Ac = A + k*360o if A is given in degrees.

or

Ac = A + k*(2 PI) if A is given in radians.

where k is any negative or positive integer.

Example 1: Find a positive and a negative coterminal angles to angle A = -200o

Which is the longest 2 km 25m 2500 cm or 3000 mm

Answers

2km=2 kilometer
kilo=1000 so 2 km=2000m

25m

2500cm
cm=centimeter=1/100 of a meter
so
2500cm=25m

mm=milimeter=1/1000 meter
so
3000mm=3m

so the longets is obviously 2000m or 2km

So,

Let's state everything in terms of meters (m).

The conversion factor between km and m is as follows:
1 km = 1000 m
Therefore, 2 km is 2000 m.

The conversion factor between cm and m is as follows:
100 cm = 1 m
Therefore, 2500 cm is 25 m.

The conversion factor between mm and m is as follows:
1000 mm = 1 m
Therefore, 3000 mm is 3 m.

Here are all the numbers in meters.
2000 m, 25 m, 25 m, 3 m

We can quickly see that 2000 m is the longest distance. It is 2 km.

What is the value of the slope of the graph of distance versus time, and what does the slope represent?

Answers

To find the slope of the graph you pick any piece of the line, and divide the vertical difference between its ends by the horizontal difference between its ends. If the graph is distance versus time then the slope represents the speed.

Emily can ride her scooter 18 miles in 50 minutes.c. What is her unit rate in miles per hour?

Answers

Answer:

22.5 miles per hour (rounded answer)

Step-by-step explanation:

This is a fraction equal to

18 miles ÷ 0.8 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 0.8

18 miles ÷ 0.8

0.8 hours ÷ 0.8

22.5 miles

1 hour

22.5 miles

hour

= 22.5 miles per hour

Answer:

there is no miles per hour because she wasn't riding for an hour
