Igoryamba

Answer:

19.6

Step-by-step explanation:

The ratio of brown paint to white paint is, 5:7 or \frac{5}{7} so if he bought 14 gallons of white paint we need to figure out:

\frac{5}{7} =\frac{14}{x}

which we can as it only has one unknown:

5x=14×7

5x=98

x=19.6

So the answer is 19.6

I don't understand this question very well

There are 10 marbles in the bag all together.
(8/10) = 80% of the marbles in the bag are white.

So if you pull a marble out of the bag, you have an 80% chance
of pulling a white one.

And if you do it many times, you expect that you'll pull
a white one out about 80% of the times.

   80% pf 45 times  =  0.8 x 45  =  36 times .

What is the midpoint of the line segment with endpoints of (-2,-2) and (4,6)?
slamgirl [31]

Answer:

option (d) is correct.

The mid points of the line segment whose ends points are (-2,-2) and (4,6) is (1,2)

Step-by-step explanation:

Given: end points of a line segment as (-2,-2) and (4,6)

We have to find the mid points of the line segment whose ends points are given.

Mid point formula is stated as ,

For a line having end points as \left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right) , the mid point can be calculated as,

\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)

Here,

\left(x_1,\:y_1\right)=\left(-2,\:-2\right),\:\left(x_2,\:y_2\right)=\left(4,\:6\right)

Substitute in mid point formula, we get,

=\left(\frac{4-2}{2},\:\frac{6-2}{2}\right)

Solving further , we get,

=\left(1,\:2\right)

Thus, the mid points of the line segment whose ends points are (-2,-2) and (4,6) is (1,2)

Thus, option (d) is correct.
