Answer:

23. $8

18. x=4p

Step-by-step explanation:

23.

$32 equals 1-1/5=4/5ths of her money (x)

32=(4/5)x

x=40

Now we know Anna has $40 dollars. If she spent 1/5th of it on the book,

40*(1/5)=8

Anna spent $8 on the book

18.

Multiply the number of boxes (p) by the number of muffins in each box (4) to get the total number of muffins (x)

Teddy has two pairs of black shoes and three pairs of brown shoes. He also has one pair of brown pants and three pairs of black

horsena [70]

Answer:

0.20 or 20%

Step-by-step explanation:

Brown shoes = 3

Black shoes = 2

Total shoes = 5

Brown pants = 1

Black shoes = 3

Total pants = 4

Brown socks =4

Black socks = 6

Red socks = 2

Total socks = 12

In order to choose shoes, pants and socks of the same color, Teddy can go either all black or all brown. For all black, there is a 2 in 5 chance he gets the right shoes, 3 in 4 chance for pants and 6 in 12 for socks. For all brown, there is a 3 in 5 chance he gets the right shoes, 1 in 4 chance for pants and 4 in 12 for socks.

$P=P(All\ black)+P(All\ brown)\\P=\frac{2}{5}*\frac{3}{4}*\frac{6}{12}+ \frac{3}{5}*\frac{1}{4}*\frac{4}{12}\\P=0.20$

The probability that he chooses shoes, pants, and socks of the same color is 0.20 or 20%.

D is between C and E, CE = 17.1 and DE = 8 Find CD

stiks02 [169]

CDE is the line segment, in which CE = 17.1, and DE = 8

Subtract 8 from 17.1

17.1 - 8 = 9.1

CD = 9.1
