Chloe has 500 marbles.
24% of them are red.
How many red marbles does she have?
Answer: 120
Step-by-step explanation: Since the equation is asking for 24% percent of 500 we will have to solve by putting them both as fractions. 24 percent automatically means the denominator will be 100 so we have 24/100. 500 is the denominator since that's the base number we are trying to solve for 24% of 500. So we put x over 500. The equation will be:
24/100 x/500
We multiply diagonally so 24*500=12000.
We then divide 500 by 100 which equals 120.
The reason why we didn't multiply 100 and x is because we are trying to solve for x so we had to simplify each side until we got what x was equal to.
Answer:
She has 120 Red Marbles
Step-by-step explanation:
1% of 500= 5 so you can do 5x24 which would be 120.

Find the perimeter and the area of ABCD with vertices A(3, 5), B(6, 5), C(4, -1), and D(1, -1). Round your answer to the nearest hundredth place, if necessary. Perimeter: Area: units square units
The perimeter of the shape is determined as 19.91 units and the area is 20.87 sq. units.
What is perimeter?
The perimeter of an object or a shape is the distance around the edge of the shape.
Length of AB = √[(6 - 3)² + (5 - 5)²] = 3 units
Length of AC = √[(4 - 3)² + (-1 - 5)²] = 6.1 units
Length BD = √[(6 - 1)² + (5 - -1)²] = 7.81 units
Length CD = √[(1 - 4)² + (-1 - -1)²] = 3 units
Perimeter of the shape ABCD = 3 units + 6.1 units + 7.81 units + 3 units = 19.91 units.
Area of the shapeThe formula for area of a trapezoid will be used to determine the area of the shape as shown below;
A = ¹/₂(6.1 + 7.81) x 3
A = 20.87 sq. units

Werner Company produces and sells disposable foil baking pans to retailers for $2.25 per pan. The variable cost per pan is as follows:
Direct materials $0.24
Direct labor 0.60
Variable factory overhead 0.73
Variable selling expense 0.17
Fixed manufacturing cost totals $115,117 per year. Administrative cost (all fixed) totals $15,698.
1. Compute the number of pans that must be sold for Werner to break even.
________ pans
2. Conceptual Connection: What is the unit variable cost? What is the unit variable manufacturing cost? Round your answers to the nearest cent.

Unit variable manufacturing cost $______
3. How many pans must be sold for Werner to earn operating income of $5,049?
______ pans
4. How much sales revenue must Werner have to earn operating income of $5,049?
$______
If Werner Company produces and sells disposable foil baking pans to retailers for $2.25 per pan, and the variable cost per pan are [Direct materials $0.24, Direct labor 0.60, Variable factory overhead 0.73, Variable selling expense 0.17] while, fixed manufacturing cost totals $115,117 per year and Administrative cost (all fixed) totals $15,698, then:
1. 256,000 Pans must be sold for Werner to break even.
2. The unit variable cost is $1.74, and the unit variable manufacturing cost is $1.57.
3. 266400 pans must be sold for Werner to earn an operating income of $5,049.
4. A sales revenue of $599,400 must Werner have to earn operating income of $5,049.
First, we have to calculate the number of pans that must be sold for Werner to break even.
Given, Fixed manufacturing costs $115,117
And, Fixed administrative costs $15698
Therefore, Total fixed costs $[tex](115,117+15,698)=130,815[/tex]
Also given, Selling price per unit $2.25
And, total Variable costs per unit $[tex](0.24+0.60+0.73+0.17)=1.74[/tex]
Contribution margin per unit = $[tex](2.25-1.74)=0.51[/tex]
[Since, contribution margin is the difference of the selling price and the variable costs]
Now, formula to calculate Break-even units goes as
(Total fixed costs / unit contribution margin).
Therefore, Break-even units in our case = [tex]\frac{130,815}{0.51}=256,000[/tex] units.
Secondly, we are required to calculate the unit variable cost and the unit variable manufacturing cost.
The unit variable cost is already calculated to be $1.74.
And, the unit variable manufacturing cost is the sum of all the variable costs excluding the variable selling expense, i.e., [tex](1.74-0.17)=1.57[/tex].
Thirdly, we will have to calculate the number of pans must be sold for Werner to earn an operating income of $5,049.
Already calculated, Total fixed costs are $130,815 and Contribution margin per unit $0.51.
Given, target operating income is $5049.
Now, formula to calculate Desired Units to earn profit goes as
(Total fixed cost + Target operating income)/(Contribution margin),
i.e., in our case, [tex]\frac{130815+5049}{0.51} = \frac{135864}{0.51}=266400[/tex] unit pans must be sold for Werner to earn an operating income of $5,049.
Lastly, We need to calculate the sales revenue must Werner have to earn operating income of $5,049.
Since, [Sales revenue = (Desired units * selling price)]
And desired units = 266400, while Selling price per unit, given as $2.25.
Therefore, Sales revenue = [tex](266,400*2.25)=599,400[/tex].
That is, a sales revenue of $599,400 must Werner have to earn operating income of $5,049.

Answer:
(a) $878.24

(c) Amy would pay less for the golf clubs if she gets them directly from the distributor
Step-by-step explanation:
Part (a)
The wholesale price is $499. When the pro shop gets them from the distributor, it has to pay a mark-up of 10%. 10% expressed as decimal is 10/100 = 0.10
10% of 499 = 0.10 x 499 = 49.90
So total cost including markup for the pro shop is 499 + 49.90 = $548.90
We can compute this directly without computing mark-up cost using the formula
Cost = 499(1+0.10) = 499 x 1.1 = 548.90
The pro shop puts a mark up of 60% which in decimal is 60/100 = 0.6 on the above cost
So the price Amy pays = 548.90(1+0.6) = 548.90 (1.6) = $874.28
Part (b)
Wholesale price = $499
If Amy purchases directly from distributor there is a 70% markup on the wholesale price. 70% = 70/100 = 0.7
So the price Amy would have to pay = 499(1+0.7) = 499 x 1.7 = $848.30
Part (c)
Since the cost of purchasing directly from distributor is less than the cost of purchasing from pro shop the answer is
Amy would pay less for the golf clubs if she gets them directly from the distributor

The probability that if it does not rain, the school bus will be on time is 0.85
The probability that it will rain and the school bus will still be on time is 0.6
In this question, we have been given the probability of rain in Nevada is 0.3
If it rains, the probability of the school bus being late is 0.4
If it does not rain, the probability of the school bus being late is 0.15
We need to find the probability that
a) it will not rain
b) If it does not rain, the school bus bring on time
c) it will rain and the school bus will be on time
The probability that it will not rain in Nevada:
= 1 - probability of rain in Nevada

The probability that if it does not rain, the school bus will be on time is:
= 1 - probability of the school bus being late if it does not rain

= 0.85
The probability that it will rain and the school bus will still be on time is:

What is volume?Every three-dimensional item takes up space in some way. The volume of this area is what is used to describe it. The area occupied within an object's three-dimensional bounds is referred to as its volume. The object's capacity is another name for it.
Finding an object's volume can help us figure out how much of it will be needed to fill it, such as how much water will be needed to fill a bottle, aquarium, or water tank.
It is shown that Volume V = πr²(9.3 - h)
Lets divide both sides with πr²
V/πr² = πr²(9.3 - h)/πr²
= 9.3 - h
Now, subtract 9.3 from both sides
V/πr²- 9.3 = 9.3 - h - 9.3
= -h
Now multiply both sides with -1
-1(V/πr²- 9.3) = -1(-h)
-V/πr² + 9.3 = h
