Answer 2

Angle 2 would also be 75 degrees.
75+75 = 150
150 + 90 = 240
240 + 75 = 316
360 - 316 = 44

Angle 1 = 75 degrees.
Angle 2 = 75 degrees Angle 3 = 150 Angle 4 = 90

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

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

Diane serves breakfast to two groups of children at a daycare center. One box of Oaties contains 12 cups of cereal. She needs 1/3 cup for each younger child and 3/4 for each older child. Today’s group includes 11 younger children and 10 older children. Is one box of oaties enough for everyone

Answers

no. It's over 12 by 1/6

Answer:

Yes, one box of Oaties is enough for everyone.

Explanation:

To find out if one box of Oaties is enough for everyone, let's calculate the total amount of cereal needed for each group and then sum them up.

For the younger children:

Number of younger children = 11

Amount of cereal needed for each younger child = 1/3 cup

Total cereal needed for younger children = Number of younger children × Amount of cereal needed for each younger child

Total cereal needed for younger children = 11 × 1/3 = 11/3 cups

For the older children:

Number of older children = 10

Amount of cereal needed for each older child = 3/4 cup

Total cereal needed for older children = Number of older children × Amount of cereal needed for each older child

Total cereal needed for older children = 10 × 3/4 = 30/4 = 7.5 cups

Now, let's sum up the total cereal needed for both groups:

Total cereal needed = Total cereal needed for younger children + Total cereal needed for older children

Total cereal needed = 11/3 + 7.5

To add fractions, we need a common denominator, which is 3 in this case:

Total cereal needed = (11/3) + (7.5 × 3/3)

Total cereal needed = (11/3) + (22.5/3)

Total cereal needed = (11 + 22.5) / 3

Total cereal needed = 33.5/3

Now, 33.5/3 cups of cereal are needed for everyone.

Since one box of Oaties contains 12 cups of cereal, let's check if it's enough:

1 box = 12 cups

So, 12 cups > 33.5/3 cups

Yes, one box of Oaties is enough for everyone.

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

tom ate 1/4 of a pizza. He divided the leftover pizza into pieces each equal to 1/12 of the Original Pizza. After he gave some friends one piece each 1/6 of the Original Pizza remained. How many friends got pizza?

Answers

To make this easy let covert everything using a LCD.

The LCD of 1/4 1/12 and 1/6 is 12. This becomes...

Tom ate 3/12 of the pizza.
Leftover pizza = 9/12.
Slices were 1/12.
X friends got pizza.
Remaining pizza is 2/12.

if each friend got 1 piece(1/12)....
9/12(Leftovers) - 2/12(remaining) = 7/12

So 7 friends got pizza.

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.

A square kitchen floor has an area of 500 ft.² estimate the length of one wall to the nearest 10th of a foot

Answers

Final answer:

To estimate the length of one wall of the square kitchen, take the square root of the area of 500 square feet, which gives approximately 22.4 feet, rounded to the nearest tenth.

Explanation:

The student is asking how to estimate the length of one wall in a square kitchen that has an area of 500 square feet. To find the length of the wall, you need to take the square root of the area because the area of a square is equal to the side length squared. Using a calculator, the square root of 500 is approximately 22.36 feet. Therefore, the length of one wall of the square kitchen is approximately 22.4 feet, rounded to the nearest tenth of a foot.

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.

Answers

Answer:

−5x − 7 < −22 and −5x − 7 ≥ −3 (the first one)

Step-by-step explanation:

22 is bigger than -5x and 7

-5x-7 is equal to or less than 22

and negative 3 is just negative 3

hope this helps!

The equivalent form of the compound inequality −22 > −5x − 7 ≥ −3 is -5x - 7 < -22 and -5x - 7 ≥ -3.

What is Inequality?

a relationship between two expressions or values that are not equal to each other is called 'inequality.

We can subtract 7 from all parts of the inequality to get:

-29 > -5x ≥ -10

Then we can divide all parts by -5 (and remember to reverse the direction of the inequality signs because we are dividing by a negative number) to get:

5.8 < x ≤ 2

So, an equivalent form of the compound inequality -22 > -5x - 7 ≥ -3 is:

-5x - 7 < -22 and -5x - 7 ≥ -3

Therefore, the equivalent form of the compound inequality −22 > −5x − 7 ≥ −3 is -5x - 7 < -22 and -5x - 7 ≥ -3.
