What is the PERCENT DECREASE: 1) PRINCETON: December - 50 January - 40 2) WORCESTER: December - 256 January - 197 3) CHICAGO: December - 7050 January - 6708

Answers

Answer: See explanation

Step-by-step explanation:

PRINCETON:

December - 50

January - 40

Decrease = 50 - 40 = 10

Percentage Decrease = Decrease/Original value × 100

= 10/50 × 100

= 20%

2) WORCESTER:

December - 256

January - 197

Decrease = 256 - 197 = 59

Percentage Decrease = Decrease/Original value × 100

= 59/256 × 100

= 23.05%

3) CHICAGO:

December - 7050

January - 6708

Decrease = 7050 - 6708 = 342

Percentage Decrease = Decrease/Original value × 100

= 342/7050 × 100

= 4.85%

Isaac walks 6/10 of a mile of a mile in 1/5 of an hour. If Isaac’s walking rate remains constant, what is Isaacs walking rate in miles per hour?

Answers

Answer:

3 miles per hour.

Step-by-step explanation:

To get his walking rate in miles per hour, we multiply 1/5 by its reciprocal, 5/1. We also multiply 6/10 by 5/1. This gets us 30/10 of a mile in an hour. We can simplify 30/10 to 3. This means he walks at 3 miles per hour.

Answers

Answer:

(-20)

Step-by-step explanation:

-4 - 2(4 + (-2) )³ = -4 - 2(4 - 2)³

                        = -4 - 2*(2)³

                       = -4 - 2* 8

                      = -4 - 16

                     = -20

Start with PEMDAS.
Do (4+-2) (4+-2) (4+-2)
Then multiply your answer by 2, so you’ll have -2(8), which gives you -16,
Lastly you would have -4-16
And then your final answer would be -20

What is the total amount of money put down by Xi-ling monthly?

Question Parameters:

Xi-ling has a net income that is 5% of her monthly salary of $2,315. Xi-ling would like to keep a net income of $50

Generally,  5% of her monthly salary   is mathematically given as

x=0.05*2315

x=115.75

Therefore, if she has a net income equal to 115.75

y=115.75-50

y=65.75

Xi-ling puts y=65.75 towards paying down debt each month.

Jason is baking a cake. The recipe calls for 2 cups of sugar for every 5 cups of flour. If he is making a small cake and is only using 1 cup sugar, how many cups of flour should he use? *

Answers

Answer:

2 1/2 cups

Step-by-step explanation:

First, our ratio is sugar:flour or 2:5, so our question is 1:? We find ? by finding how we got to 1 on the other side.

2 ÷ 2 = 1

And what we do to one side, we always have to do to the other to make it proportional, so

5 ÷ 2 = 2.5 or 2 1/2

So, if Jason is using 1 cup of sugar, he should use 2 1/2 cups of flour

Sam builds 360 toys in 8 hour. At that rate,how many toys would he build in 4 minutes

Answers

Answer:

He can build 3 toys in 4 minutes.

Step-by-step explanation:

Divide 360 by 8 since you are dividing it first to get the number of toys he can build in an hour.  As a result, he can build 45 toys in an hour.  Divide that number by 15 since 4 times that number equals an hour.  You should get 3 toys as your final result.  

For easier explanation, multiply 8 and 15 together to get 120 for better understanding.  Divide that number from 360 to get the same answer.
