Answer:

He can do 13 push ups in one

Step-by-step explanation:

If he can do 65 in 5 and you have to find for one its like finding the unit rate.

So you have to divide the 65 he can do in 5 by 5 so 65÷5

Once you do this you'll get 13 which is how much he does in one

The newly elected president needs to decide the remaining 8 spots available in the cabinet he/she is appointing. If there are 14

Elanso [62]

Answer:

The members of the cabinet can be appointed in 121,080,960 different ways.

Step-by-step explanation:

The rank is important(matters), which means that the order in which the candidates are chosen is important. That is, if we exchange the position of two candidates, it is a new outcome. So we use the permutations formula to solve this quesiton.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

If there are 14 eligible candidates for these positions (where rank matters), how many different ways can the members of the cabinet be appointed?

Permutations of 8 from a set of 14. So

$P_{(14,8)} = \frac{14!}{(14-8)!} = 121,080,960$

The members of the cabinet can be appointed in 121,080,960 different ways.

$z_1=4+2i\\z_2=-1+2i\\\overline(z_2)=\sqrt{(-1)^2+(2i)^2}=\sqrt{1-4}=i\sqrt{3}\\ z_1+\overline(z_1)=4+2i+\sqrt{4^2+(2i)^2}=4+2i+\sqrt{16-4}=4+\sqrt{12}+2i\\z_2+\overline(z_2)=-1+2i+\sqrt{(-1)^2+(2i)^2}=-1+2i+\sqrt{1-4}=-1+(2+\sqrt{3})i$

A pea seller had some peas. He sold 40% of his stock and still had 420 peas. Originally, he had how many peas?

Zielflug [23.3K]

100-40= 60%

60% = 0.60

420/0.60 = 700

1. Find the equation of the line that is parallel to the line y = 0.6x-3 and passes through the point (-2,2).

AnnZ [28]

So the equation is parallel and the slope will be 2
y=0.6x+b
sub in(-2,2) for x and y to find b
2=0.6(-2)+b
2+1.2=b
b=3.2
therefore the equation is y=0.6x+3.2
