Mary bought a bag of parsnips that weighed 2 1/4 pounds. She also bought a bag of turnips that weighed 3 times as much as the parsnips. How many pounds of turnips did Mary buy?

Answers

Step-by-step explanation:

2 1/4 is improper fraction, because it's 21/4. To simplify;

21/4 = 21/4  

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.  

21/4 = 5 1/4

With 21/4 simplified into 5 1/4, you would then do 5 1/4•3 which would be;

15.75

The rectangular prisim below has a total surface area of 158 in use the net to determine the missing dimension

Answers

Answer:

The problem seems to be incomplete, after an online search I couldn't find the complete question, to be able to solve the question, I will assume that the known measure is the width W.

For a rectangular prism of length L and width W, the surface area is calculated as:

S = W*L

For the assumption we took, we have:

W = 39.5ft

And we also know that S = 158 ft^2

And we want to find the missing dimension, in this case is L, then we need to solve:

158 ft^2 = W*L

We just need to divide both sides by the known measure, W

We get:

(158 ft^2)/W = L

So you just need to replace the known value, and can find the missing one.

When Jennifer and Tom visit another country, they find two types of coins are used there, one with a Q on it and one with an E on it. Jennifer has 13 Q coins and Tom has 5 Q coins and 7 E coins. If Jennifer's coins have a total value of $0.65 and Tom's coins have a total value of $3.75, what is the value of each type of coin?

Answers

Answer:

q = $0.05

e = $0.5

Step-by-step explanation:

13q = 0.65 equation 1

5q + 7e = $3.75   equation 2

in equation 1, divide both sides of the equation by 13

q = 0.65 / 13 = 0.05

Substitute for the value of q in equation 2

5(0.05) + 7e = 3.75

0.25 + 7e = 3.75

collect like terms

3,75 - 0.25 = 7e

3.5 = 7e

e = 0.5

A company's flexible budget for 12,500 units of production showed sales, $50,000; variable costs, $20,000; and fixed costs, $15,000. The operating income expected if the company produces and sells 15,000 units is:

Answers

Answer: $21000

Step-by-step explanation:

First, we calculate the contribution margin which will be:

=Sales - Variable cost

= $50,000 - $20,000

= $30,000

Therefore, the contribution margin per unit will then be:

= $30,000 / 12500

= $2.4 per unit

The operating income will be the difference between the total contribution margin and the fixed cost. This will be:

The total Contribution margin will be:

= $2.4 × 15000

= $36000

Fixed costs = $15000

Operating income = $36000 - $15000

= $21,000

3 A headline misreported
that 95% of students
purchased books for
class. By how many
percentage points was
the headline off?

Answers

The headline was off by 5 percentage points.

What is percentage ?

Percentage is a way of expressing a fraction or ratio as a number out of 100. It is a common way of measuring quantities or values that are relative to a whole. For example, if there are 100 students in a class, and 75 of them passed an exam, we can say that the pass rate is 75%, which means that 75 out of 100 students passed the exam.

To calculate a percentage, we can use the formula:

Percentage = (Part / Whole) x 100%

According to the question:
If the actual percentage of students who purchased books for class was different from the reported percentage of 95%, we can find the difference between the two percentages to determine how many percentage points the headline was off.

Let's say the actual percentage of students who purchased books for class was x%. Then the difference between the actual percentage and the reported percentage is:

Difference = |Reported percentage - Actual percentage|

Difference = |95% - x%|

For example, if the actual percentage was 90%, then the difference would be:

Difference = |95% - 90%|

Difference = |5%|

Difference = 5%

This means that the headline was off by 5 percentage points.

The amount of money in dollars earned by Nicole in 12 hours will be $96.

What is the rate?

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

Nicole earned $72 in 9 hours. Then the amount of money in dollars earned by Nicole each hour is calculated as,

Rate = $72 / 9

Rate = $8 for each hour

At this rate, the amount of money in dollars earned by Nicole in 12 hours will be calculated as,

⇒ $8 x 12

⇒ $96

The cash in dollars acquired by Nicole in 12 hours will be $96.

Find the value of x to the nearest tenth. In a triangle, one angle is 46 degree and second angle is 20 degree. The adjacent side of 46 degree angel is 7 and opposite side is x.

Answers

The value of x in the triangle is approximately 7.2 to the nearest tenth.

To determine the value of x in the triangle, we can use the trigonometric ratio of tangent (tan).

We are Given that one angle of the triangle is 46 degrees and the adjacent side to this angle is 7, we need to find the length of the opposite side (x).

The tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side.

tan(46°) = x/7

Take the tangent of both sides of the equation:

tan(46°) = x/7

Multiply both sides by 7 to isolate x:

7 x tan(46°) = x

Use a calculator to find the tangent of 46 degrees:

tan(46°) ≈ 1.0355

Multiply 7 by the approximate value of the tangent:

7 x 1.0355 ≈ 7.249

Rounding the value of x to the nearest tenth, we find that x ≈ 7.2.

Therefore, to the nearest tenth, the value of x in the triangle is approximately 7.2.

The value of x to the nearest tenth is approximately 5.0.

To find the value of x, we can use the trigonometric relationship of the sine function in a right triangle. In this case, we have an angle of 46 degrees and the opposite side x.

The sine function is defined as the ratio of the length of the opposite side to the length of the hypotenuse. However, in this case, we don't know the length of the hypotenuse, but we can still find the value of x using the adjacent side.

Let's label the angle of 46 degrees as A, the adjacent side as B, and the opposite side as C.

sin(A) = C / B

sin(46°) = x / 7

To find the value of x, we can rearrange the equation:

x = 7 * sin(46°)

Using a calculator, we can evaluate sin(46°) and calculate the value of x:

x ≈ 7 * 0.7193

x ≈ 5.0351
