Find the slope of each line

Gordan and Harry had 340 marble,altogether.After Gordan gave away 2/5 of his marbles and harry gave away 20 of his marbles, they

BARSIC [14]

109.8
you take 240 and subtract that from 2/5.Then you subtract 20 and that gives you 219.6.Since they have the same amount of marbles left,you have to divide 219.6 by 2 and your answer is 109.8
(I just used a calculator)

For this problem, assume there are 5 grey females, 4 grey males, 2 white females, and 6 white males. As in the book, the biologi

Leni [432]

Answer:

The required probability is 0.04411

Step-by-step explanation:

The number of female grey mice = 5.

The number of males grey mice = 4.

The number of female white mice = 2.

The number of male white mice = 6.

The number of mice = 17.

The probability of first mice be male grey = $\frac{4}{17}$

The probability of second mice be male grey = $\frac{3}{16}$

The probability of two mice be male grey = $\frac{4}{17} *\frac{3}{16}$ = 0.04411

Question 18

ira [324]

Answer:

The function which represents this sequence will be:

$a_n=-15n+110$

Hence, option (A) is true.

Step-by-step explanation:

Given the sequence

$95, 80, 65, 50, ...$

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

computing the differences of all the adjacent terms

$80-95=-15,\:\quad \:65-80=-15,\:\quad \:50-65=-15$

As the difference is the same, so

$d = -15$

as

$a_1=95$

Thus, substituting $d = -15$ , $a_1=95$ in the nth term of an arithmetic sequence

$a_n=a_1+\left(n-1\right)d$

$a_n=-15\left(n-1\right)+95$

$a_n=-15n+110$

Therefore, the function which represents this sequence will be:

$a_n=-15n+110$

Hence, option (A) is true.

Given a situation involving a dilation, how do you determine the scale factor.

USPshnik [31]

Answer:

See explanation below.

Step-by-step explanation:

The scale factor can be found by dividing two corresponding side lengths. For instance, if you have two triangles, divide the new length of the larger or smaller triangle by the same side length of the original.

If the side length of the new was 9 and the old was 3 then the scale factor would be 9/3 = 3.

If it were flipped then the new would be 3 and the old would be 9. So the scale factor would be 3/9 = 1/3.
