Answer:

8

Step-by-step explanation:

since there are 12 girls we have an x amount of girls who brought sleeping bags and 12-x for those who didn't. so

x/12=2/3

multiply both sides by 12

(x/12)12=(2/3)12

x=8

Hope that helps :)

He started with 17 quarter's. He had a certain number of quarters he added to his collection each day, on day two he had 26, and two days later he had 35, meaning he increased the amount of quarters my 9 over two day's, so I subtracted 9 from 26 because if you do you can remove the quarters he added in from the ones he started with, so the answer is: He started with 17.

The edge of each cube used to build this rectangular prism is 13

kolbaska11 [484]

Answer:

$\frac{3}{3} * \frac{2}{3} *\frac{3}{3} =\frac{2}{3} \ in^3$

====================================================

Step-by-step explanation:

The question is missing the attached figure.

The edge of each cube used to build this rectangular prism is 1/3 inch long. Based on the attached figure.

the volume of the prism = length × height × width

length = $3 * \frac{1}{3} = \frac{3}{3}$

height = $3 * \frac{1}{3} = \frac{3}{3}$

width = $2 * \frac{1}{3}= \frac{2}{3}$

So the volume of the prism = $\frac{3}{3} *\frac{3}{3} *\frac{2}{3} =\frac{2}{3} \ in^{3}$

∴ The equation that shows the volume of the prism, in cubic inches

= $\frac{3}{3} * \frac{2}{3} *\frac{3}{3} =\frac{2}{3} \ in^3$

Evaluate the given expression. Subscript 5 Baseline P Subscript 2 a. 40 c. 25 b. 32 d. 20

Leto [7]

Answer:

d. 20

Step-by-step explanation:

The given question implies 5 permutation 2, i.e $_{5}$ $P_{2}$ .

But,

$_{n}$ $P_{r}$ = $\frac{n!}{(n - r)!}$

So that for $_{5}$ $P_{2}$ , n = 5 and r = 2.

$_{5}$ $P_{2}$ = $\frac{5!}{(5 - 2)!}$

= $\frac{5!}{3!}$

= $\frac{5*4*3*2!}{3*2!}$

Cancel out 3 and 2 with respect to the numerator and denominator.

$_{5}$ $P_{2}$ = 5 * 4

= 20

Therefore,

$_{5}$ $P_{2}$ = 20

So that the correct option is D.

Find the quadratic polynomial if zeros of it are 2 and 1/3 respectively

muminat

Answer:

$\boxed{\sf \ \ \ 3x^2-7x+2 \ \ \ }$

Step-by-step explanation:

Hello,

There are a lot of polynomials which have 2 and 1/3 as zeroes,

I can show you one below

$3(x-2)(x-\dfrac{1}{3})=(x-2)(3x-1)=3x^2-x-6x+2=3x^2-7x+2$

hope this helps
