Answer:

It took him 2 hours and 28 minutes to do his tasks.

Step-by-step explanation:

All we need to do is add all of the minutes it took him to complete all of his tasks, so:

75 + 48 + 25 = 148

There are 60 minutes in one hour.

60*2 = 120

148 - 120 = 28

My name is Ann [436]
We have to calculate the volume of the right rectangular prism.
lenght=4 1/2 in=(4+1/2) in=9/2 in
width=5 in
height=3 3/4 in=(3+3/4) in=15/4 in

Volume (right rectangular prism = lenght x width x height.
volume=9/2 in * 5 in * 15/4 in=675/8 in³

we calculate the volume of this little cube.
volume=side³
volume=(1/4 in )³=1/64 in³

Now, we calculate the number of small cubes are needed to fit the right rectangular pris by the rule of three.

1 small cube----------------1/64 in³
x---------------------------------675/8 in³

x=(1 small cube * 675/8 in³) / 1/64 in³=5400 small cubes.

Answer: we need 5400 small cubes to fit the right rectangular prism.

In what situation can you use only multiplication to find equivalent fractions to a given fraction given example?
olya-2409 [2.1K]
To find equivalent fractions, multiply the numerator<span> AND denominator by the same nonzero whole number. This procedure is used to solve example 4. You can multiply the </span>numerator<span> and the denominator of a fraction by any nonzero whole number, as long as you multiply both by the same whole number! Hope this helped! :)</span>

What is the equation of the line that passes through the points (0,4) and (3,-2)?
Nadusha1986 [10]

***NOTE: Please check that you wrote the numbers in the question/answer choices correctly. The answer to this problem doesn't match the answer choice. Thank you!

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

First let's find the slope (m)

The formula to find slope using two points is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =-2\\y_{1} =4\\x_{2} =3\\x_{1} =0

^^^Plug these numbers into the formula for slope...

\frac{-2-4}{3 - (0)}

\frac{-6}{3}

-2

^^^This is your slope

Here is what we have so far for the slope intercept formula:

y = -2x + b

Now we must find b

To do that you must plug in a point the line goes through in the x and y of the equation, then solve for b

For this explanation we will use the point (0,4) although you could also do it with point (3, -2) and you should get the same answer  

4 = -2(0) + b

4 = 0 + b

4 = b

NOTE: For this particular problem you wouldn't technically need to go through the steps above to find b. In this case one of the points given, (0, 4) is already the y-intercept of the line (b)

y = -2x + 4

Hope this helped!

Find the x-intercept of the graph of the equation: 4x + y = 3
Anon25 [30]

The x-intercept is where the y is zero. So, we have just enough info :) Simply plug in 0 for y in order to find x.

4x + 0 = 3

x = 3/4

so the x intercept is (3/4, 0)
