Tom walked at a consistent pace from the economy parking garage to the airport terminal. He stood on a a moving sidewalk for 2/5

Mariulka [41]

Let x be the number of minutes for his normal walk

On the way to the airport, for the 2/5 (or 40%) of his route, his speed is twice faster. Hence, the number of x should be divided to 2. The rest of the route (60%) was on his normal pace. The total minutes is 6. The equation is:

0.4(x÷2) + 0.6x = 6

Solving for x, the number of minutes for his normal walk is 7.5 minutes.

ZA and B are supplementary angles.

yKpoI14uk [10]

Answer:

135°

Step-by-step explanation:

a supplementary angle is equal to 180°. since you already have the measure of ZA, all you need to do is subtract 45°, the measure of ZA, from 180°, the total measure of a supplementary angle, in order to figure out the measure of ZB.

180 - 45 = 135, therefore the measure of ZB = 135°.

A fitness center runs a contest for customers who enroll in its annual membership plan. The customers are allowed to draw a coup

Alchen [17]

There are 35 coupons in the jar.
The probability to choose coupon for 1 month of extended membership is $p(A)= \frac{20}{35} = \frac{4}{7}$ .
The probability to choose coupon for 1.5 months of extended membership is $p(B)= \frac{10}{35} = \frac{2}{7}$ .

Answer: With probability $\frac{4}{7}$ a customer will get 30 days extended membership, 
with probability $\frac{2}{7}$ a customer will get 450 days extended membership,
with probability $\frac{1}{7}$ a customer will get 60 days extended membership.
The probability to choose coupon for 1 month of extended membership is $p(C)= \frac{5}{35} = \frac{1}{7}$ .
Together P(A)+P(B)+p(C)=1.
