Answers

Answer 1

Answer:

Answer:

2/7

Step-by-step explanation:

So we multiply 3 by 2, and get 6.

Then we multiply 1 by 4, and get 4.

Next we give both terms new denominators -- 4 × 2 = 8.

So now our fractions look like this:

6/8 - 4/8

6 − 4 = 2

So the answer is:

2/8

If there is a 30% chance a student will fail a class at Fresno State, find the probability that of four randomly chosen students.All fail a class.

Answers

Answer:

81%

Step-by-step explanation:

If there is a 30 percent chance a student will fail a class at Fresno State, we can simply multiply the percentage by the probabilities of all students failing. Every option available:

P(All four fail) = 1 student fails * 2 students fail * 3 students fail * 4 students fail

P(All four fail) = 0.3 * 0.3 * 0.3 * 0.3

P(All four fail) = 0.0081

0.0081 = 81%

A hallway measuring 90 feet x 7 feet requires 1/2 a fluid ounce of cleaning solution per square foot. How much cleaning solution is required to clean the hallway?

Answers

First, find the area of the hallway.

$Area=length*width$

$A=90*7$

$A=630$

Now you know there are 630 square feet to be cleaned. To find the amount of cleaning solution needed, multiply this number by 1/2.

$Solution=area* (1)/(2)$

$S=630* (1)/(2)$

$S= (630)/(2)$

$S=315$

Answer: 315 fluid ounces

$90*7 = 630ft ^(2) \n \n 1/2 floz ->1 ft^(2) \n \n 630/2=315 \n\n\boxed{315}$

The speed of a body falling freely from rest in a vacuum varies directly with the length of the time it falls. If after 6 seconds, a body was falling 58.8 m/s, how fast was it falling 4 seconds later? (Round off your answer to the nearest meter per second.)

Answers

Answer:

The body is falling at 98 m/s after 4 seconds later.

Step-by-step explanation:

The magnitude of the speed of a body dropped from rest is:

$v = gt$

So, if the speed of a body dropped after 6 seconds is 58.8 m/s, after 4 seconds later is:

$v = gt = 9.81 m/s^(2)*(4s + 6s) = 98.1 m/s = 98 m/s$

Hence, the body is falling at 98 m/s after 4 seconds later.

I hope it helps you!
