Answer 1

Answer:

Answer:

$42

Step-by-step explanation:

To find the percent of a number, you first have to divide 100 by your percent(3%), since percent is out of 100.

100÷3=33 1/3

You can use this number to divide in your total price(1400) to get 3%

1400÷33 1/3=$42

Hence your answer

D. $42

Express your answer in simplest form.

B.10 2\3
quarts

C.11 1\3

D.11 2\3

Answers

2 1/3 quarts per batch, and five batches, so you multiply 2 1/3 x 5.

2 1/3 = 7/3 and 5 x 7/3 = 35/3 which simplifies to 11 2/3, so D. is the answer.

If you would like a more detailed answer just ask.

When 2 fractions refer to the same whole explain why the fraction with a lesser denominator has larger pieces than the fraction with a greater denominator

Answers

The denominator tells how many pieces the whole is broken into. So a denominator of two tells you that the whole is broken into two pieces. A denominator with 8 tells you that the whole is broken into eight pieces. Think of a pie. if it is cut into two pieces that's two halves. if it is cut into 8 pieces then that is eighths.

Jeff has 1/2 pizza left in the fridge . at breakfast he ate 1/3 of it. what fraction of the original pizza dose he have left for lunch?

Answers

Subtract 1/2 - 1/3

Convert into denominators of 6:

3/6 - 2/6 = (3-2)/6 = 1/6

So he will have 1/6 of pizza left for lunch.

(1-1/2)=1/2
(1/2)-(1/3)=1/6
This leaves Jeff with 1/6 of the original pizza.

D.
w > 20 and w may be a negative number.

since a dog has to weigh something, and its weight cannot be negative, "w" will have to be a positive number

The population for town A increases from 1346 to 1500. In the same period, the population of town B increases from 1546 to 1800.A.) find the percent increase for towns A and B?
B.) which town had the greater percent in increase?

Answers

In the given question, two very important information's are provided.
Firstly the population of town A increses from 1346 to 1500
Then the total increase in population of town A = 1500 - 1346
   = 154
Percentage of increase in population of town A = (154/1346) * 100
      = 11.44
So the population of town A increases by 11.44%
Secondly the population of town B increases from 1546 to 1800
Then the total increase in population of town B = 1800 - 1546
   = 254
Percentage increase in population of town B = (254/1546) * 100
   = 16.42
So the population of town B increases by 16.42%
Also town B had the greater percentage increase in population.
