what is the volume of the prism ?

Answer:

3.715

Step-by-step explanation:

7.802/2.1 = 3.715

Answer:

  1 2/3 hours

Step-by-step explanation:

At constant speed, the time is proportional to the distance.

  time/distance = 2.5 h/150 mi = x /100

  x = 100(2.5/150) h = 5/3 h = 1 2/3 h

It will take the train 1 2/3 hours to travel 100 miles.

Answer:

8x - 22

Step-by-step explanation:

You can't do anything because in order to subtract 22 from 8x the 22 has to have an x behind it as well. :) hope this helps! (Can I get brainliest? If not it ok! ^w^)

9514 1404 393

Answer:

Step-by-step explanation:

The marked angles are supplementary, so you have ...

  (4x +30) +(3x +10) = 180

  7x +40 = 180

__

Subtracting 40 gives ...

  7x = 140

  x = 140/7 . . . . . divide by the coefficient of x

  x = 20

__

Then the angle measures are ...

  4x +30 = 4·20 +30 = 110°

  3x +10 = 3·20 +10 = 70°

Answer: [tex]\geq[/tex] 9 lawns, assuming Fiona spends 1 hour per lawn.

Step-by-step explanation:

Let Y = the amount earned from mowing a lawn.  Let z be the number of hours worked on that lawn.

Y = $10 + $5(z)

We need to know the number of hours, z, for any particular lawn to be able to make this a valid equation.  Not having that, we really can't set up a valid equation.  

But let's assume z=1 for each and every lawn and see what we'd have.

Y = $10 + $5

Y = $15/lawn.

Fiona needs at least $135 for her Broadway ticket.

Let L be the number of lawns mowed.  We need:

L*($15/lawn) [tex]\geq[/tex] $135

L  [tex]\geq[/tex] 9 lawns

Answer:

-2

Step-by-step explanation:

Answer:

D, -2

Step-by-step explanation:

Take a look at the number inside the function "f" which is 2. now know that it is a number you are supposed to substitute in the place of x .. therefore : f(2) = 5(2) - 12 = 10 - 12 = -2.

Answer:

1 mile

Step-by-step explanation:

1 hour = 3 miles

20 minutes is 1/3 of an hour, so he walks 1 mile

6.182m against the wall from the ground

Well this is a tricky one though but very easy.

So we have on our hands a 6.50m long ladder leaning against a wall at an angle of 72°, as illustrated in the diagram above. (please parden my hand writing).

So we are to find how high the ladder is against the wall, which from the diagram I labelled as y, and to find y we have to use something called SOHCAHTOA. This basically is use in calculating some lengths of a right angle triangle when Pythagoras therom fails u .

So from SOHCAHTOA, we are going to use SOH

What this basically means is

The sin of an angel(for example x) can be found by dividing the opposite to the angle by the hypotenuse. Since we are finding for y

Sin(72°) = y/6.50, if we should cross multiple the we will be having

Y = sin(72°) * 6.50

After evaluating using your calculator,

You will have y = 6.182

+400, +50, 50 - 400, 50 + (-400) = -350

+400, -120, -120 - 400, -120 + (-400) = -520

+400, -75 3/4, -75 3/4 - 400, -75 3/4 + (-400) = -475 3.4

-200, +610, 610 - (-200), 610 + 200 = 810

-200, -50, -50 - (-200), -50 + 200 = 150

-200, -500, -500 - (-200), -500 + 200 = -300

-200, 0, 0 + 200, 0 - (-200) = 200

-200, 120 1/2, 120 1/2 - (-200), 120 1/2 + 200 = 320 1/2

I think this might be the answer.

Answer:

let x stand for number of weeks

135+15x>=480

x>=23

Step-by-step explanation:

subtract 135 on both sides

15x>=345

divide by 15 on both sides

x>=23 is your solution

Answer: -8/15

Step-by-step explanation:

-(2/15)/(1/4)

-[(2/15)/(1/4)]*(4/4)

= (-2/15)*(4/1)

= -8/15

Answer:

answer is the number 5

Step-by-step explanation:

First you square root 9 which is 3. Then u  3-1=  2.   then u times 2 by 6 which equals = 12. Then minus 7 from this number.    12-7=5            ur number is 5.

Answer:

C

Step-by-step explanation:

Based on the amount that she paid in the first month, the amount Ronda will pay for the next month is $396.

When a loan is amortized, it means that one can pay it off by paying the same amount every period until they would have paid off both the loan and the associated interest.

The amortized amount contains:

In conclusion, as the amount is the same every time, Ronda will have to pay the same amount of $396 the next month.

Answer:

109 degrees

Step-by-step explanation:

Since AB is a straight line, we know the line is 180 degrees in total. So, with this information, subtract 180 with 29 and 42.

I think it might be 109°. AB is a straight line so it would have a degrees of 180, so I think all you have to do is add the two other degrees (42+29) which would give you 71, and then subtract 71 from 180.

Hopefully this answer is right but sorry if it isn't.

Answer:

-2 inches per hour

Step-by-step explanation:

Finding the average rate of change is just like finding the slope. So, take the y values (height) and subtract them and divide that by the difference in the x values (time).

( 3 - 9 ) / ( 8 - 5 )

= -6 / 3

= -2 inches per hour
