Half of Ethan string is equal to 2/3 of Kayla stream the total length of the string is 10 feet how much longer is Ethan string K

Verizon [17]

Answer:

10/7 feet

Step-by-step explanation:

Let e = Ethan

k = Kayla

The following equations can de derived from the equation :

1/2 e = 2/3k

multiply both sides of the equation by 2

e = 4/3k --- 1

e + k = 10 --- 2

Substitute for e in equation 2

4/3k + k = 10

7/3k = 10

multiply both sides of the equation by 3/7

k = 30/7

Substitute for k in equation 1

e = (4/3) x 30/7 = 40/7

difference in length = 40/7 - 30/7 = 10/7

A high school class consists of 7 seniors, 10 juniors, 12 sophomores, and 11 freshmen. Exactly 4 of the juniors are female,

jekas [21]

Answer:

1/13

Step-by-step explanation:

There exactly 7 seniors 10 Juniors, 12 sophomores and 11 freshman

in which 4 of the juniors are Female , and exactly 2 of the sophomores are male. Therefore,

10-4= 6 juniors are male

12-2 = 10 female sophomores

Total = 7+10+12+11= 40 students

P(male junior then female soph.)= $\frac{6}{40}\times\frac{10}{39}= \frac{1}{26}$

P(female soph then male junior)= $\frac{10}{40}\times\frac{6}{39}= \frac{1}{26}$

Therefore the final answer will be = 1/26 +1/26= 1/13
