Answers

20 divide by 3 equals 6.66666666667 as a whole number.
As a fraction it is 20/3

Answer:

[tex]6\frac{2}{3}[/tex]

Step-by-step explanation:

Candy buys 20 ounces of mixed nuts.

She puts an equal number of ounces in each 3 bags.

In each bag she can put = [tex]\frac{20}{3}[/tex]

                                         = [tex]6\frac{2}{3}[/tex]

She can put [tex]6\frac{2}{3}[/tex] ounces of nuts in each bag.

Six people share 3/5 pound of peanuts equally. What fraction of a pound of peanuts does each person receive?


Answers

So first, I would convert 3/5 to 6/10, because it is equivalent and easier.

You can then just deduce that 1/10 would be 1/6 of 6/10, and that each person would therefore get 1/10 of a pound of peanuts.

You could also divide 3/5 by 6.

3/5 / 6 = 3/5 * 1/6

3/5 * 1/6 = 3/30

3/30 = 1/10

If P(A) = 0.5, P(B) = 0.3, and P(A or B) = 0.6, find P(A and B)

Answers

P(A or B) = P(A) + P(B) - P(A and B), which means that the probability that A or B occurs is equal to the probability that A occurs plus the probability that B occurs minus the probability that both A and B occur.

So, you know P(A), P(B) and P(A or B) and you can solve for P A and B) =>

P(A and B) = P(A) + P(B) - P(A or B)

P(A and B) = 0.5 + 0.3 - 0.6 = 0.8 - 0.6 = 0.2

Answer: P(A and B) = 0.2



A vehicle uses 1 1/8 gallons of gasoline to travel 13 1/3 miles. At this rate , how many miles can the vehicle travel per gallon of gasoline? Show your work.

Answers

13 1/3 miles = 40/3 miles
1 1/8 gallons of gasoline  = 9/8 gallons of gasoline

(40/3) / (9/8)
= 40/3 x 8/9
= 320 /27
= 11 23/27 miles gallon of gasoline

Answer:

13 1/3 miles = 40/3 miles

Step-by-step explanation:

1 1/8 gallons of gasoline  = 9/8 gallons of gasoline

(40/3) / (9/8)

= 40/3 x 8/9

= 320 /27

= 11 23/27 miles gallon of gasoline

Determine the missing information in the paragraph proof.

Given: Line PQ contains points (w, v) and (x, z) and line P'Q' contains points (w + a, v + b) and (x + a, z + b). Lines PQ and P'Q' are parallel.

Prove: Parallel lines have the same slope.



Since slope is calculated using the formula , the slope of both lines is equivalent to ________. It is given that the lines are parallel, and we calculated that the slopes are the same. Therefore, parallel lines have the same slopes.




Answers

Slope = change in y / change in x
Slope of PQ = (z - v) / (x - w)

Slope of P'Q' = (z + b - (v + b)) / ((x + a) - (w + a))
Slope of P'Q' = (z - v) / (x - w)

The slopes of both lines are equivalent to 
(z - v) / (x - w)

0.561 rounded to the nearest hundredth is what

Answers

0.56 4 and below round it down, 5 and above round it up.
0.561 rounded to the nearest hundredth is 0.56. Remember the 10th and 100th places in decimals, 10th being the place of the 5, and 100th being the place of the 6. When rounding, you only raise it if the number you are given is higher than 5. Because it's just a 1, in this case you can just take it off.

A line passes through the point (-6, 6) and (-6, 2). In two or more complete sentences, explain why it is not possible to write the equation of the given line in the traditional version of the point-slope form of a line

Answers

Try writing it in point-slope form and you will see why you have a problem.

slope m is equal to (y2-y1)/(x2-x1):

m = (y2-y1)/(x2-x1) = (2-6)/(-6 - -6) = -4/0

The denominator has a zero, so it is undefined.

Since the point-slope form requires "m" to be defined, you can't write the equation of the line using point-slope form.

ratio 5 to 15 in a fraction lowest term

Answers

To do this, divide the numerator and denominator by the GCF. In this case, it's 5.

5:15
5 ÷ 5: 15÷5
1:3

Hope this helps!
To solve this ratio, we must first find the GCF, or the Greatest Common Factor, that is, the largest number that fits into both numbers. We can set up a table to compare the factors of each individual number, then identify common factors between the two numbers.

15 |  1  3  5  15
 5 |  1  5

We see that the common factors include 1 and 5, however, 5 is the greatest common factor. Now we can simplify the ratio by dividing both numbers by 5.

5/5  = 1
15/5 = 3

Simplified Ratio: 1:3 (which is 1/3).

consecutive even integers are 2 apart

so they are x and x+2


their sum is x+x+2

the sum is -50

On a shopping trip, Peter spent 1/3 of his money for a jacket and another $5 for a hat. If peter still had 1/2 of his money left, how much money did he have originally ??

Answers

He should have started with $30.
Let m be the amount of money he had

m - (1/3)m - 5 = (1/2)m
(2/3)m - 5 = (1/2)m
Subtract both sides by (1/2)m
(2/3 - 1/2)m - 5 = 0
(1/6)m - 5 = 0
Add both sides by 5
(1/6)m = 5
Multiply both sides by 6
m = 30

Peter started with 30 dollars.

you live 3.67 miles from your grandparents and you are biking how do you solve this

Answers

To solve for revolutions, we will have to take the distance of the travel and divide that by the circumference of the wheel.

Distance of travel = 3.67 miles
Circumference of wheel = 82.6 inches

We have to convert the inches to miles. There are 63360 inches in one mile.

Circumference of wheel = 82.6 in * (1 mi/63360 in) = 0.0013 miles

Revolutions = Distance/Circumference = 63,538.46 revolutions

A linear function is one whose formula can be written in the form

Ax + By = C  where A, B, C are real numbers and A, B are not both 0.  (This is standard form, too.)

[tex]\frac{x+4}{2} = \frac{y-4}{3}[/tex]

"Cross multiply."

[tex]3(x+4) = 2(y-4) \\ 3x+12 = 2y-8[/tex]

Subtract 12.

[tex]3x=2y-20[/tex]

Subtract 2y.

[tex]3x-2y=-20[/tex]

This matches up with standard form with A = 3, B = -2, C = -20.
