Applying the central angle theorem, the measure of angle ABC is: a. 36°
What is the Central Angle Theorem?The central angle theorem states that the angle measure of a central angle equals the measure of the intercepted arc.Inscribed angle = half the intercepted arc.Given:
m∠ADC = (7x + 2)° (central angle)
measure of intercepted arc AC = (8x - 8)°
Therefore:
(7x + 2)° = (8x - 8)°
Solve for x7x + 2 = 8x - 8
8 + 2 = 8x - 7x
10 = x
x = 10
Thus:
m∠ABC is an inscribed angle = half of measure of intercepted arc AC
Therefore:m∠ABC = 1/2(8x - 8)°
Plug in the value of xm∠ABC = 1/2[8(10) - 8]
m∠ABC = 36°

Find the surface area of a rectangular prism with base 4 m by 5 m and height 8 m.
Answer:
Step-by-step explanation:
surface area=area of sides +area of top and bottom
=2(4+5)×8+2×(4×5)
=2[(9×8)+20]
=2[72+20]
=2×92
=184 m²
The total surface area of the given rectangular prism is square meters.
How to calculate the surface area of a rectangular prism?The surface area of a rectangular prism can be calculated by adding the areas of all its faces.
Given that a rectangular prism with a base 4 m by 5 m and a height 8 m,
The surface area can be calculated as follows:
The surface area = area of sides + area of top and bottom
The surface area = 2(4+5)×8+2×(4×5)
The surface area = 2[(9×8)+20]
The surface area = 2[72+20]
The surface area = 2 × 92
The surface area = 184 m²
Therefore, the total surface area of the rectangular prism is 184 square meters.

5. A standard-size volleyball court has an
area of 1,800 square feet. The length of the
court is 60 feet. What is the width of the
court?
Answer: The width of the court is 30 feet.
Step-by-step explanation:
We know that the area of a rectangle is given by :-
Area = length x width (1)
Given : A standard-size volleyball court has an area of 1,800 square feet.
The length of the court is 60 feet.
To find : The width of the court.
According to (1) , we have
[tex]1800 = 60\times \text{width}[/tex]
Then,
[tex]\text{Width}=\dfrac{1800}{60}=30[/tex]
Hence, the width of the court is 30 feet.
Final answer:
The width of a standard-size volleyball court, with an area of 1,800 square feet and a length of 60 feet, is calculated to be 30 feet using the formula for the area of a rectangle.
Explanation:
To find the width of a standard-size volleyball court with an area of 1,800 square feet and a length of 60 feet, we need to use the formula for the area of a rectangle, which is Area = length × width. Since we know the area and the length, we can solve for the width.
Let the width be w feet.
Then, 1,800 sq ft = 60 ft × w ft,
So, w = 1,800 sq ft / 60 ft,
Therefore, w = 30 feet.
The width of the volleyball court is 30 feet.
Original Price: $125
Discount: ?
Sale Price: $81.25
Answer:
The discount is 43.75 dollars.
Step-by-step explanation:
125 - 81.25 = 43.75
Final answer:
The discount percentage applied to reduce the original price of $125 to the sale price of $81.25 is 35%.
Explanation:
A student is trying to find out the discount percentage that was applied to an item originally priced at $125 to have a final sale price of $81.25. To calculate the discount, one can use the formula: Discount percentage = ((Original Price - Sale Price) / Original Price) imes 100%. Applying this to the given values: ($125 - $81.25) / $125 imes 100% = $43.75 / $125 imes 100% = 35%. Thus, the discount percentage applied is 35%.
Strawberries cost $2.14 per pound and Annie purchased 1.3 pounds. How much did she pay for strawberries if her answer is rounded to the nearest cent?
A. $2.78
B. $2.79
C. $27.82
D. $27.90
Answer:
A. $2.78
Step-by-step explanation:
You would multiply the cost per pound, $2.14, by the amount of pounds bought, 1.3. Then round to the nearest hundredth.
2.14 x 1.3 = 2.782
2.782 rounded to the nearest hundredth is $2.78
Answer:
I think it is 2.78 sorry if it’s not

If gasoline costs $47.86 for 12.5 gallons of gasoline, how much does it cost for 8 gallons?
Round your answer to the nearest cent.
Answer:
8 gallons of gasoline costs $30.63.
Step-by-step explanation:
Set up a proportion to solve for x, or the cost of 8 gallons of gasoline. The $47.86 goes on top of the first ratio, and 12.5 goes on top of the second. This is because the $47.86 is the cost of the 12.5 gallons of gasoline. Next, put x on the bottom of the first ratio and 8 on the bottom of the second ratio. This is because the amount of money you are trying to find, x, is the cost of the 8 gallons of gasoline. The proportion should look like this: [tex]\frac{47.86}{x} = \frac{12.5}{8}[/tex]
To solve the proportion, use cross multiplication. To do that, multiply 8 by 47.86 to get 382.88. Then, divide 382.88 by 12.5. The answer is 30.6304, so round to the nearest cent to get a total of $30.63.

need help with 3x48 and 48x3
Answer:
144
Step-by-step explanation:
48×3= 144
48×3=144
to make it easier just add the number being multiplied the amount of times its being multiplied.
48+48+48=144
Both 3x48 and 48x3 yield the same result, which is 144, because multiplication is commutative.
Both expressions involve multiplying the numbers 3 and 48.
In the first expression, 3x48 means you're multiplying 3 by 48. This gives you 144, because 3 times 48 equals 144.
In the second expression, 48x3 means you're multiplying 48 by 3. This also gives you 144, because multiplication is commutative, which means the order of the numbers doesn't change the result. So, whether you multiply 3 by 48 or 48 by 3, you'll always get the same answer, which is 144.
So, to summarize:
3x48 = 144
48x3 = 144
Both expressions result in the same value of 144.

The manufacturer of cell phones spends $320 to make each cell phone and sells them for 440 . The manufacturer also has fixed costs each month of $11400 .
Answer:
x=95
Step-by-step explanation:
320x+11400=440x
320*95+11400=440*95
30,400+11,400=41,800
41,800=41,800
The manufacturer needs to sell approximately 95 cell phones to cover its fixed costs of $11,400 per month. The profit per month depends on the number of units sold, with a contribution margin of $120 per unit after covering variable costs.
To analyze the manufacturer's costs and profitability, we can break down the information provided:Cost to Make Each Cell Phone: $320 per unitSelling Price of Each Cell Phone: $440 per unitFixed Costs: $11,400 per monthFirst, let's calculate the variable cost per unit, which is the cost to make each cell phone:Variable Cost per Unit = Cost to Make Each Cell Phone = $320Now, we can calculate the contribution margin per unit, which is the amount each phone contributes to covering fixed costs and generating profit:Contribution Margin per Unit = Selling Price - Variable Cost per UnitContribution Margin per Unit = $440 - $320 = $120Next, calculate the break-even point in units, which is the number of units the manufacturer needs to sell to cover its fixed costs:Break-Even Point (in units) = Fixed Costs / Contribution Margin per UnitBreak-Even Point (in units) = $11,400 / $120 ≈ 95 unitsSo, the manufacturer needs to sell approximately 95 cell phones to cover its fixed costs.To determine the profit, we can calculate the profit per month after covering fixed costs:Profit per Month = (Selling Price - Variable Cost per Unit) * Number of Units Sold - Fixed CostsSuppose the manufacturer sells "X" cell phones per month. Then:Profit per Month = ($440 - $320) * X - $11,400Now, you can calculate the profit for any given number of cell phones sold.For more questions on profit -
