Answer:

1) (m - 6n)

2) 12p³

3) (1 + 5w - (-7w²))

Step-by-step explanation:

19m^2n - 114mn^2

19mn(m) - 19mn(6n)

19mn(m - 6n)

24p^3t + 60p^3 =

12p³(2t) + 12p³(5)

12p³(2t + 5)

5wz + 25w^2z + 35w^3z

5wz(1) + 5wz(5w) + 5wz(7w²)

5wz(1 + 5w + 7w²)

5wz(1 + 5w - (-7w²))

Answer:

(m-6n)

12p^3

19m^{2}n-114mn^2=19mn\\19mn(m-6n)=19mn \\

24p^{3t}+60p^3=(*********)(2t+5)

24p^{3t}+60p^3\\24\left(p^t\right)^3+60p^3\\2\cdot \:12\left(p^t\right)^3+5\cdot \:12p^3\\12\left(2\left(p^t\right)^3+5p^3\right)\\12\left(2p^{3t}+5p^3\right)\\12(2p^3 p^t+5p^3)\\12p^3(2 p^t+5)

5wz\:+\:25w^2z\:+\:35w^3z\:=\:5wz\\5wz+25w^2z+35w^3z-5wz=5wz-5wz\\35zw^3+25zw^2=0\\5zw^2\left(7w+5\right)=0

Considering just the LHS:

5wz\:+\:25w^2z\:+\:35w^3z\:\\5wz(1+5w+7w^2)\\5wz(1+5w-(-7w^2))

The formula for the size of a file that was downloaded over time t and at an average rate r is r.t.
lakkis [162]

Answer:

The size of file downloaded is  <em>88 megabytes.</em>

Step-by-step explanation:

Given that:

Average rate of downloading the file = r

Time taken to download = t

Formula for the size of file downloaded = r.t

Rate of downloading, r = 800\ kilobytes/sec

Time taken, t = 110 seconds

To find:

Size of file downloaded in megabytes = ?

Solution:

First of all, let us apply the given formula to find the size of file downloaded:

Size of file downloaded = r.t

Size of file downloaded = 800 kilobytes seconds \times 110 seconds =

<em>88000 kilobytes</em>.

Now, let us convert the unit kilobytes to megabytes to find the answer.

<em>Conversion formula:</em>

1000 kilobytes = 1 megabyte

Let us use unitary method to find the number of megabytes in 88000 kilobytes.

1 kilobytes = \frac{1}{1000} megabytes

88000 kilobytes = \frac{1}{1000} \times 88000 megabytes

\Rightarrow <em>88 megabytes.</em>

Therefore, the size of file downloaded is  <em>88 megabytes.</em>

100 POINTS 10 QUESTIONS PLEASE HELP PICTURES BELOW PLEASE SPECIFY WHICH QUESTION YOU ARE ANSWERING
Semenov [28]

Answer:

The answers are \frac{2}{5}, \frac{1}{4}, \frac{1}{10}, \frac{5}{2}, \frac{5}{8}, \frac{4}{1}, \frac{8}{5}, and \frac{10}{1}.

Step-by-step explanation:

Proportions are fractions that can be made by using the given numbers, which in this case are 2, 5, 8, and 20. Let's pair each one with the other three and then simplify if possible.

First, let's begin with 2:

\frac{2}{5} = \frac{2}{5}

\frac{2}{8} = \frac{1}{4}

\frac{2}{20} = \frac{1}{10}

Then, let's do 5:

\frac{5}{2} = \frac{5}{2}

\frac{5}{8} = \frac{5}{8}

\frac{5}{20} = \frac{1}{4}

Note that we already have \frac{1}{4}, so we do not need to include an additional one.

Now, let us do 8:

\frac{8}{2} = \frac{4}{1}

\frac{8}{5} = \frac{8}{5}

\frac{8}{20} = \frac{2}{5}

See how we already have \frac{2}{5}, so we won't have to include that as well.

Finally, let's do 20:

\frac{20}{2} = \frac{10}{1}

\frac{20}{5} = \frac{4}{1}

\frac{20}{8} = \frac{5}{2}

Now see that we already have both \frac{4}{1} and \frac{5}{2}, so we won't have to include both of them, as they are both extras.

Hence, the answers are \frac{2}{5}, \frac{1}{4}, \frac{1}{10}, \frac{5}{2}, \frac{5}{8}, \frac{4}{1}, \frac{8}{5}, and \frac{10}{1}.

Solve for w pls help thank u
masya89 [10]

Answer:

w = -19

Step-by-step explanation:

-6w + 4(w +3) = 26

-6w + 4w + 12 = 26

simplify

-2w + 12 = 26

now get the variable and the numbers on different sides

-2w + 12 - 12 = -2w

26 + 12 = 38

-2w = 38

now divide each side by -2

-2w / -2 = w

38 / -2 = -19

w = -19
