In a basketball game 15 of 20 foul shots that Michelle attempted were successful. What percent of her shots were not successful?
mestny [16]
<u>Work 1:</u>
   Successful Percent:

     15 divided by 20 equals .75
     .75 times 100 is equal to 75
     75%
   Not successful Percent:
     
100% minus 75% equals 25%
     <em>25%</em>
<u>Work 2:</u><u />
     20 minus 15 equals 5
     5 divided by 20 is equal to .25
     .25 times 100 is equal to 25
     <em>25%</em>

6w-19 + k when<br> w=8 and k = 2
ddd [48]

Answer:

31.

Step-by-step explanation:

1. Write out the problem.

6w-19 + k; w=8 and k=2

2. Figure out the first part of the problem.

So, if w=8 and 6 and w are next to each other, we should multiply 6*8, which is 48. Next, it says to subtract 19. 48-19=29.

3. Find out what the last part of the problem is.

Since the first part of the problem is 29 and k=2, we should add 29+2=31, which is the final answer.

Hope this helped :)

The figure below is made of 2 rectangular prisms.<br><br>What is the volume of this figure?
mixer [17]

Answer:

6536 cubic in

Step-by-step explanation:

1. Split both the prisms apart- In doing so, you can simplify the problem.

2. Put in the #'s for the formula which in this case is V=L*W*H, we will start with the formula for the front one, V=7*8*1 or V=7*8

3. answer for the front is 56 cubic in, now we solve for the other half.

4. V=9*1*90 or V=9*90 which is 6480 cubic in.

5. add 6480 and 56 and your answer is 6536 cubic in as your answer.

Hope this helped ;D

It will take Adam four hours to drive to Disney Park, and 2.5 times less time if driving 45 mph faster. What is the distance Ada
Mashcka [7]
<h2>Hello!</h2>

The answer is:

The distance to over by Adam to get to the park is 108 miles.

<h2>Why?</h2>

To solve the problem, we need to write two equations using he given information about the times and his speed.

So,

For the first equation we have: Travel to Disney Park

time=4hours

Distance=v*4hours

For the second equation we have: Travel back from Disnery Park

time=4hours-2.5hours=1.5hours

Speed=v+45mph

Distance=(v+45mph)*1.5hours

Then, if Adam covered the same distance going and coming back, we have:

v*4hours=(v+45mph)*1.5hours

v*4hours=v*1.5hours+45mph*1.5hours

v*4hours-v*1.5hours=45mph*1.5hours

v*2.5hours=67.5miles

v=\frac{67.5miles}{2.5hours}=27\frac{miles}{hour}=27mph

We have that the speed when he was going to Disney Park was 27 mph.

Now, to calculate the distance, we need to substitute the obtained speed in any of the two first equations.

Therefore, substituting the speed into the second equation, we have:

Distance=(v+45mph)*1.5hours

Distance=(27mph+45mph)*1.5hours=72mph*1.5hours=108miles

Hence, we have that the distance that Adam should cover to get to the park is 108 miles.

Havea nice day!
