c. The horizontal axis labeled Hours Driven goes from 0 to 15 in increments of 1 and the vertical axis labeled Miles Remaining goes from 0 to 150 in increments of 10. The line starts at left parenthesis (0, 0), and passes through (1, 65) and (2, 130)

Step-by-step explanation:

The given parameters are;

The speed of the truck = 65 miles per hour

The length of the highway = 130 miles

Therefore, from the given information, we have;

The time, t, it will take the truck to arrive at the end of the highway is given as follows;

Time = Distance/speed = 130/65 = 2 hours

Therefore, if the truck timing starts from the point (0, 0), we have;

The points on the straight line (constant) speed graph are;

(0, 0), (1, 65), and (2, 130)

Answers

Given:

Kinetic energy (KE)= 100,000 J

Mass (m)= 800 kg

To find:

The velocity of the object to the nearest hundredth.

Solution:

We know that,

[tex]KE=\dfrac{1}{2}mv^2[/tex]

where, KE is kinetic energy (in J), m is mass (in kg) and v is velocity (in m/s).

Put KE=100000 and m=800 in the above formula.

[tex]100000=\dfrac{1}{2}(800)v^2[/tex]

[tex]100000=400v^2[/tex]

Divide both sides by 400.

[tex]\dfrac{100000}{400}=v^2[/tex]

[tex]250=v^2[/tex]

Taking square root on both sides.

[tex]\sqrt{250}=v[/tex]

[tex]v=15.8113883[/tex]

[tex]v\approx 15.81[/tex]

Therefore, the velocity of the object is 15.81 m/s.

Answers

Answer:

The temperature changed by [tex]-12^\circ F[/tex] overnight.

The temperature changed by [tex]-1^\circ F[/tex] overnight each hour.

Step-by-step explanation:

Given that:

Temperature at 7 PM last night = [tex]10^\circ F[/tex]

Temperature at 7 AM the next morning = [tex]-2^\circ F[/tex]

a. The change in temperature from 7 PM to 8 AM = Temperature at 7 AM - Temperature at 7 PM

[tex]\Rightarrow -2-10 =\bold{-12^\circ F}[/tex]

Negative sign indicates that the temperature has decreased.

b. Change in temperature each hour:

Divide the Change in temperature with the number of hours.

[tex]\Rightarrow \dfrac{-12}{12} = \bold{-1^\circ F}[/tex]

Negative sign indicates that the temperature has decreased.

You can also use the circumference and radius equation.

a school's enrollment decreased from 3000 to 2250 students. what is the percent of decrease​

Answers

Answer:

25%

Step-by-step explanation:

You can do this on a calculator or just look it up!

Happy To Help!

Answer:  25% decrease

===============================================

Work Shown:

A = old value = 3000

B = new value = 2250

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (2250-3000)/3000 ] * 100%

C = (-750/3000) * 100%

C = -0.25*100%

C = -25%

Since C is negative, we have a 25% percent decrease.

Another indication we have a percent decrease is that B < A.

man drove his car a distance of 366 miles in 6 hours. If continuing at this rate is possible, he will travel ____ miles in 7 hours.

Numerical Answers Expected!

Answers

Answer:

the answer is 427miles in 7 hours

Step-by-step explanation:

Answer:

427 miles in 7 hours.

Step-by-step explanation:

All we need to do is figure out how many miles per hour he's traveling, and then add it to the pre-existing 6 hour number we already have.

So, he drove 366 miles in 6 hours. We need to find out how many miles per hour (MPH) he's doing. To do this all we need to do is divide the amount of miles he's gone (366) by the number of hours it's taken him (6).  It looks like this:

366 ÷ 6 = 61.

So he's goes 61 miles every hour. Now all we need to do is add up until we hit 7 hours. We already know he went 366 miles in 6 hours, so we only need to add 61 to 366 once.

366 + 61 = 427.

427 is your answer.

Hope this helps and have a nice day!

the sum of two consecutive integers is 62. what are the two consecutive integers?

Answers

Answer:  So our two integers are 17 and 45.

Step-by-step explanation:

The two integers are 17 and 45, See how we got it. X+Y=62. Substitute our first expression here for y, we have X+2X+11 =62.

Given that,

the two numbers are consecutive(also odd)

The two numbers are

x and x + 2

Sum of the numbers = 62

x + (x + 2) = 62

x + x + 2 = 62

2x = 62 - 2

2x = 60

x = 60/2

x = 30

Therefore, the two numbers are x = 30 and x + 1 = 32
