Mira picked two numbers from a bowl. The difference of the two numbers was 4, and the sum of 1/2 of each number was 18. The system that represents Mira’s numbers is below.
x – y = 4
1/2x + 1/2y = 18
Which two numbers did Mira pick?
10 and 8
18 and 4
20 and 16
40 and 32

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

answer: haha (: i’ll go see what it is

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
