BOOKS The owner of a bookstore
surveyed every 10th person that
entered the store to determine her
customers' preferred type of book.
Of these, 32% preferred mysteries.
If the owner will order 500 new books,
about how many should be mysteries?

Answer:

7.3333333

Step-by-step explanation:

1 2/3 - (- 5 2/3) = 22/3 = 7 1/3= 7.3333333


detailed:
Conversion a mixed number 1 2/3

to a improper fraction: 1 2/3 = 1 2/3 = 1 · 3 + 2/3 = 3 + 2/3 = 5/3

To find a new numerator:

a) Multiply the whole number 1 by the denominator 3. Whole number 1 equally 1 * 3/3 = 3/3

b) Add the answer from previous step 3 to the numerator 2. New numerator is 3 + 2 = 5

c) Write a previous answer (new numerator 5) over the denominator 3.

One and two thirds is five thirds

Conversion a mixed number -5 2/3

to a improper fraction: -5 2/3 = -5 2/3 = -5 · 3 + (-2)/3 = -15 + (-2)/3 = -17/3

To find a new numerator:

a) Multiply the whole number -5 by the denominator 3. Whole number -5 equally -5 * 3/3 = -15/3

b) Add the answer from previous step -15 to the numerator 2. New numerator is -15 + 2 = -13

c) Write a previous answer (new numerator -13) over the denominator 3.

Minus five and two thirds is minus thirteen thirds

Subtract: 5/3 - (-17/3) = 5 - (-17)/3 = 22/3

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 3) = 3. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 3 = 9. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - five thirds minus minus seventeen thirds = twenty-two thirds.

Answer:

184,900

Step-by-step explanation:

First divide.

Do a division problem, 2150 / 86.

The result is 25.

Now, setup the multiplication.

86 x 2150

How many times does 86 go into 2150? 25 times.

now we have 2150.

Use the lesser number we started with, 86, and then multiply it by the biggest number, 2150.

This would give us 184900.

I hope this strategy helps you! The strategy is to find the least common multiple of the multiplier, keep it in your head, multiply the least common multiple by the multiplier. multiply the multiplier by the first number in this case 2150, and you get the final result.

Answer:

97% HAD TUSKS

2% HAD NO TUSKS

end

87% HAD TUSKS

12% HAD NO TUSKS

Answer:

= 10

Step-by-step explanation:

[tex]r + (s+1)^{2}[/tex] ÷ [tex]3[/tex]

if, r = 7 and s = 2

SO..

[tex]7 + (2+1)^{2}[/tex] ÷ [tex]3[/tex]

..

Add 2 and 1 to get 3.

[tex]7 + \frac{3^{2} }{3}[/tex]

Calculate 3 to the power of 2 and get 9.

[tex]7 + \frac{9}{3}[/tex]

Divide 9 by 3 to get 3.

7 + 3 = 10

Answer:

If the 5 students could do it in 2 hours then it would take one person 10 hours. 10/x=y.

Step-by-step explanation:

rawr! brainliest pleasee~ ~hailey

Answer:

1. Anything to do with the same slope but different a B (Ex.  y=1/3x+1 and y=1/3x-8)

2. No solutions

Step-by-step explanation:

1. Because the two lines are parallel, when no intersection between two lines happens, there will need to be a change in the B but the same slope. Remember the formula for an equation is y=mx+b. The m stands for the slope. With parallel lines, slopes are the same. If lines were to never intersect, you would have to change the b to a different number so that both lines could keep going at the same time, but never intersect.

2. Remember, solutions only happen when the two lines intersect. Infinite solutions happen when the lines are the same. One solution happens when two lines only have one point where they intersect. No solutions happen when the two lines don't intersect at all. Based off the graph given, there are no intersections so, there will be no solutions.

Answer:

12%

Step-by-step explanation:

Since the percentage of those who choose to listen to music is 28% and 16% for the ones who chose to read books, we will minus 16 from 28.

----------------------

28%-16% = 12%

Answer:

The mean is the arithmetic average of a set of given numbers. The median is the middle score in a set of given numbers. The mode is the most frequently occurring score in a set of given numbers

Step-by-step explanation:

Mean: the sum of all values divided by the number of values

Mode: the value that appears the most in the data set

Median: the value separating the higher half from the lower half

 /=divide

Answer:

Each side is 3/4 yard, and the shape is a square. This means that you will need to multiply 3/4 by 3/4.

3/4 x 3/4

=

(3 x 3) + (4 x 4)

19/16sqyd

Answer:

It is 9/16, but if you are giving brainliest, don't give it to me. pls give it to the other person, I think he meant to say 9/16 plus he got here first so pls give it to them instead.

Answer: 3

Step-by-step explanation: just do it lie this 2x-3. 3 is you're lager number so that 2x turnes into 2x3. always remember pemdas multiplication first 2x3=6 so now we do 6-3 which equals 3.  

Answer:

44

Step-by-step explanation:

0.2(x – 4.5) + 1.7 = 9.6

0.2x - 0.9 + 1.7 = 9.6

0.2x + 1.7 = 10.5

0.2x = 8.8

x = 44

Have a great day!

PLEASE MARK BRAINLIEST!

Answer:

44

Step-by-step explanation:

1. Distribute.  0.2 times x = 0.2x.  0.2 times -4.5 = -0.9.

2. Simplify.  0.2x-0.9+1.7 = 9.6

-0.9+1.7 = 0.8 --> 0.2x+0.8 = 9.6

3. Solve for x:

- subtract 0.8 from both sides: 0.2x = 8.8

- divide both sides by 0.2: x = 44

Answer:

Step-by-step explanation:

All of the dashes on the number line represent a quarter of a pound of soap flakes or 1/4 or 0.25.

Multiply the number of x's on each dash by the number that dash represents.

1 x over 0.25 dash

1 x 0.25 = 0.25

4 x's over 0.5 dash

4 x 0.5 = 2

2 x's over 0.75 dash

2 x 0.75

and so on.

At the end add all of the products together. (Should have 6 products in all.)

If you end up with a decimal, the whole number is your answer.

Answer:

Read the explanation

Step-by-step explanation:

This is the weight of all the boxes and the # of them

1 box is 0.25 pounds

4 boxes are 0.5 pounds

2 boxes are 0.75 pounds

1 box is 1 pound

3 boxes are 1.25 pounds

2 boxes are 1.75 pounds

multiply and add to get 12

So he will fill 12 bags

Answer:

Part A: x > -60

Part B: 3. <--------o

Step-by-step explanation:

If the researchers explored a deeper depth than -60, that means the depth of the second dive must be more deeper than -60, not equal to it. so x > -60, and deeper depth means more larger negatives, and open circle stands for greater than/less than, so 3. would be the appropriate answer. hope this helps
