A machine produces open boxes using square sheets of metal. The machine cuts equal-sized squares measuring 2 inches on a side f

docker41 [41]

Answer:

width 9'' length 9''

Step-by-step explanation:

2 " is cut off from both sides

so the base of the box will be a square

area * height = volume of box

side = x

height =2

2x^2=162

x^2=81

x=9 inches the side of the box

Volume =162

V=area*height V= 81*2= 162

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 88 megabytes.

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 =

88000 kilobytes.

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

Conversion formula:

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

$\Rightarrow$ 88 megabytes.

Therefore, the size of file downloaded is 88 megabytes.

7(h-4)=2h+17 help plzz

S_A_V [24]

7(h-4) = 2h + 17 distribute to get:
7h - 28 = 2h + 17 subtract 2h from both sides to get:
5h - 28 = 17 add 28 to both sides to get:
5h = 45 divide 5 from both sides to get:
h = 9

How do you write and equation of a linear function using two points

Margaret [11]

Answer:

Step-by-step explanation:

Find the difference between the 2 points.

For example, (8, 9) (5, 3).

Compare the difference between the x's, in this case 8 and 5. The difference is 3. Do the same with the y's, 9 and 3. The difference is 6.

To find the slope, it's y/x. The slope in this situation is 6/3. Simplify. The slope is 2.

To find the y-intercept, insert the slope and one of the 2 points in the beginning into y = mx + b & solve for b.

For example, if we use the ordered pair (5, 3) the equation would look like:

3 = 2(5) + b, Solve for b.

Multiply. 3 = 10 + b

Get b by itself by adding - 10 to both sides.

-7 = b

The y-intercept is -7. So, in this case, the equation is y = 2x - 7.
