A Movie Theatre Marks Up The Price Of Popcorn 12 3/4 Times The Original Cost. Express 12 3/4 As A Percent

Answers

Answer 1

Answer:

Answer: F. 1,275% and 12.75.

Step-by-step explanation:

Ratios

Ratios are usually expressed as decimals, fractions, colon notation, and percentages.

For example, if the ratio of two quantities is 2, it can be expressed as:

2, 2/1, 2:1, 200%

To obtain the percentage expression, just multiply by 100%.

The price of the popcorn sold at a movie theatre was marked up as 12 3/4 times the original cost.

The mixed fraction can be converted to a decimal by just adding their parts as follows:

12 + 3/4 = 12.75

Now to express it as a percentage, multiply by 100%:

12.75 * 100% = 1,275%

Answer: F. 1,275% and 12.75.

The matrices show the number of indoor and outdoor volunteers in different age groups

create a matrix that shows the total number of indoor and outdoor volunteers in different age groups. name the matrix T.

what is the value of the element t11 and what does the value indicate?

create a matrix by subtracting the women's matrix from the mens matrix. name the matrix D.

what is the value of the element at d12 and what does that value indicate? ​

Answers

Answer:

(a) M + W = Indoor= [26 55] Outdoor = [32 49]

(b) The value indicates the sum of the indoor volunteers ages 18-39 so the Value would be, 34.

(c) M – W = Indoor = [8 15] Outdoor = [-16 3]

(d) This value indicates the difference of the volunteers indoors 40. So the value would be 15.

Step-by-step explanation:

If this is wrong my apologies i tried LOL

but i will let you know when i get the results back asap!

The value of the element t11 is 34 and the value of the element at d12 is 15.

When are two matrices called being equal?

Two matrices are equal if and only if their shapes are same, and they've got the same elements for each corresponding row and column positions.

M + W = Indoor= [26 55] Outdoor = [32 49]

The value indicates the sum of the indoor volunteers ages 18-39,

Therefore, the Value would be, 34.

To create a matrix by subtracting the women's matrix from the mens matrix.

Now the difference;

M – W = Indoor = [8 15] Outdoor = [-16 3]

This value indicates the difference of the volunteers indoors 40 so

Therefore the value would be 15.

in the equation (m^5/6) (m^1/6)^7 = m^x , what is the value of x that makes the equation true?

Answers

The value of x in the equation (m^5/6) (m^1/6)^7 = m^x is 2

What is the law of exponent?

The exponents of numbers are added when the numbers are multiplied, subtracted when the numbers are divided, and multiplied when raised by still another exponent: a^m×a^n = a^(m+n); a^m÷a^n = a^(m−n);

(am)ⁿ = a^mn.

Given an equation, (m^5/6) (m^1/6)^7 = m^x

Using the law of exponent, we get,

(m^5/6) (m^1/6)^7 = m^5/6*m^7/6

= m^(5/6+7/6)

= m^12/6

= m^2

Hence, the value of x in the equation (m^5/6) (m^1/6)^7 = m^x is 2

The ratio of blueberries to strawberries in a fruit salad is 4:3. If there are 45 strawberries in a salad, how many blueberries are there.. Blueberries 4 Strawberries 3

Answers

Answer:

60 blueberries

Step-by-step explanation:

Given the ratio of blueberries to strawberries in a fruit salad to be 4:3. The total ratio = 4+3 = 7

If there are 45 strawberries in the salad then we can first calculate the total mixture of both as shown;

amount of strawberries = 3/7 * x = 45

x is the total amount of mixture

from the expression;

3x/7 = 45

cross multiply

3x = 7*45

3x = 315

x = 315/3

x = 105

The amount of blueberries present = 105 - 45 = 60

Hence the amount of blueberries present is 60 blueberries

A 14 foot long ramp is being built to access a front door in a house. The door is 5 feet above the ground. How far away from the base of the house must the ramp be placed? What angle will the ramp make with the ground?

Answers

Answer:

The ramp must be placed 13.08 feet from the base of the house.

The angle the ramp will make with the ground is 20.92°.

Step-by-step explanation:

An illustrative diagram for the scenario is shown below.

In the diagram, d represents the distance of the door from the ground, r represents the length of the ramp and x represent the distance of the ramp from the base of the house.

To determine how far away from the base of the house the ramp must be placed, that is to determine x in the diagram.

The diagram is a right angle triangle and x can be determine using the Pythagorean theorem which states " the square of the hypotenuse equals sum of the squares of the other two sides"

In the diagram, the hypotenuse is r

∴ r² = d² + x²

r = 14 ft

d = 5 ft

∴ 14² = 5² + x²

196 = 25 + x²

Then, x² = 196 - 25

x² = 171

x = √171

x = 13.08

Hence, the ramp must be placed 13.08 feet from the base of the house.

Now, to determine what angle the ramp will make with the ground, that is θ in the diagram.

From the formula

Sinθ = Opposite / Hypotenuse

In the diagram, opposite = d = 5ft

and Hypotenuse = r = 14ft

∴ Sinθ = 5ft / 14ft

Sinθ = 0.3571

∴ θ = Sin⁻¹(0.3571)

θ = 20.92°

Hence, the angle the ramp will make with the ground is 20.92°.

Noah pays $7.65 for a cappuccino on days he's running late to work. One week, he was late on Monday, Wednesday, and Friday. How much did he spend (in $) on cappuccinos that week? $

Answers

Answer:

Amount Noah spent on cappuccino for that week = $22.95

Step-by-step explanation:

Noah pays $7.65 for a cappuccino on days he's running late to work

Cost of cappuccino per day = $7.65

One week, he was late on Monday, Wednesday, and Friday.

That is 3 days in a week

How much did he spend (in $) on cappuccinos that week? $

Amount Noah spent on cappuccino = cost of cappuccino per day × 3 days

= $7.65 × 3

= $22.95

Amount spent on cappuccino for that week = $22.95

Some people advise that in very cold​ weather, you should keep the gas tank in your car more than half full. Irene​'s car had 6.4 gallons in the 14​-gallon tank on the coldest day of the year. Irene filled the tank with gas that cost ​$3.90 per gallon. How much did Irene spend on​ gas?

Answers

Answer:

$24.96

Step-by-step explanation:

Total number of gallons irede had in his tank = 6.4gallons

Price per gallon is $3.90

To get the cost of 6.4gallons;

If 1 gallon = $3.90

6.4gallons = $x

Cross multiply

1 * x = 3.90 * 6.4

x = 24.96

Hence Irene spent $24.96 on gas

Solve 3.8 = 2x - 11.2.
X=__

Answers

Answer:

x= 15/2 im pretty sure

Step-by-step explanation:

We want to solve the given linear equation, we will find that the solution is x = -3.7

Solving linear equations:

Here we have the equation:

3.8 = 2*x - 11.2

We want to solve this for x, so we can start by subtracting 11.2 in both sides to get:

3.8 - 11.2 = 2*x

-7.4 = 2*x

Now we can divide both sides by 2:

-7.4/2 = x = -3.7

So the solution is x = -3.7

She was an adventurous and fun-loving child. That adventurous spirit remained as she grew older. One day in 1920, after going on a plane ride, she was determined to fly planes. She worked at any job she could find to save up for flying lessons, which cost $1,000. At one point, she worked as a nurses aid and a social worker. Six months after receiving flying lessons, Amelia bought her own plane, and she flew as high as 14,000 feet, which set a world record for female pilots. A short time afterward, Amelia became the sixteenth female to earn a pilots license. In 1928, an opportunity arose for Amelia to participate in a transatlantic flight across the Atlantic Ocean as a copilot. This experience later came in handy when she became the first woman to fly solo across the Atlantic in 1938. She received many honors for this achievement, such as the Distinguished Flying Cross from Congress.As Amelia approached her fortieth birthday, she was planning her biggest trip yet: She wanted to be the first woman to fly around the world. Of course, she needed a lot of help to make this happen. She made a first attempt that failed and damaged her plane. But Earhart was not one to give up, so she made another attempt at the ground-breaking mission. She did make some progress by flying 7,000 miles to New Guinea but did not make it to her next stop, Howland Island. Sadly, Earharts plane disappeared, and, despite search and rescue attempts, she was never found. To this day, Earhart is known and celebrated for her bravery, persistence, and commitment to aviation.Which sentence from the passage contains information that could best be used to create a yearbook blurb about Amelia Earhart?As Amelia approached her fortieth birthday, she was planning her biggest trip yet.
