How many pounds is a quarter of a ton?

Answers

there is 500 because there is 2000 in a ton and 1/4 of 2000 is 500
There are three major units called tons. 

1 US (short) ton = 2000 lb so one fourth is 500 lbs. 
1 UK (long) ton = 2240 lb; one fourth is 560 lbs. 
1 tonne (metric) = 2204.6 lb; one fourth is 501.15 lbs.

The perimeter of a rectangle is 50 inches. The width of the rectangle is 10 inches. What is the length of the rectangle?

Answers

the answer is 15 inches. because the opposite side to 10 inches is the same we can subtract 20 from 50. that leaves us with 30. divide that by two and you get 15.
First, add 10 and 10 because you know that is the length of two sides (because they're equal). When you do that, you get 20. 50-20=30. Then you need to divide by two to find the length of 1 of the remaining sides. When you do that you get 15. So the length is 15 inches.

Jamal has the following choices for his pizza: white sauce or red sauce; white cheese or yellow cheese; and mushrooms, pepperoni or sausage. What is the probability that he creates a pizza that has red sauce and mushrooms?

Answers

Answer:

The probability that he creates a pizza that has red sauce and mushrooms are:

                         (1)/(6)

Step-by-step explanation:

Jamal has the following choices for his pizza:

White sauce or red sauce; white cheese or yellow cheese; and mushrooms, pepperoni or sausage.

Let A denote the event of choosing a red sauce.

and B denote the event of choosing a mushroom.

Let P denote the probability of an event.

Now we know that event A and event B are independent.

We are asked to find:

                         P(A∩B)

Since the two events are independent.

Hence,  

P(A\bigcap B)=P(A)* P(B)

P(A)=(1)/(2)

( Since out of 2 choices i.e. white sauce or red sauce , we have to choose red sauce)

and

P(B)=(1)/(3)

( Since, out of 3 choices i.e. mushrooms, pepperoni or sausage we have to choose mushroom)

Hence, the answer is:

P(A\bigcap B)=(1)/(2)* (1)/(3)

i.e.

P(A\bigcap B)=(1)/(6)
the probability of jamal making a pizza with red sauce and mushrooms is 2/7
