Rectangle - 12*19 = 228
Half a circle - [tex]\pi r^2 = \pi 6^2 = 36 \pi/2 = 18 \pi [/tex]
In the end there are 2 rectangles (2*228 = 456) and 1 full circle (18*2 = 36), which makes the shaded area 456 ft and 36[tex] \pi [/tex]
Then find the area of the semi-circle above it, which is pi times the radius squared. The diameter is 12ft, and we know the radius is half of the diameter, so the radius is 6ft. Our equation is pi times 6^2, or pi times 36.
We’ll just make pi 3.14, so 36•3.14=113.04 feet.
Add the area of the semi-circle and the rectangle together to get one of the shaded areas. 228+113.04= 341.04.
Now that we know the full area of one shaded region, we multiply it by two because there’s two of them. 341.04•2= 682.02.
Since we round it to the nearest foot, our final answer is that the shaded area of the basketball court is 682 square feet.

[tex] \frac{3}{x} + 2 = \frac{2}{x} - 1 [/tex]
1) Start off by multiplying both sides by x to simplify the problem:
[tex]\frac{3}{x} + 2 = \frac{2}{x} - 1 \\ x(\frac{3}{x} + 2) = (\frac{2}{x} - 1)x\\ 3 + 2x = 2 - x [/tex]

Joel is mailing a large envelope to his cousin. The envelope has pictures inside, so he doesn't want to bend it.
The mail slot has the dimensions shown. The dotted line shows the widest part of the slot.
Answers
Answer: 25
Step-by-step explanation:
Pythagorean theorem
c=√a²±b²
So it was 7=A
And it was 24=b
solving that it gives us 25
This isn’t that much of help sorry but this is the basic info on how to solve it you can learn more by searching videos about the Pythagorean thermom.
Hope this helps-A
The maximum width of the slot is 25cm (Option A).
To find the maximum width of the mail slot, we need to calculate the length of the diagonal (the dotted line) in the rectangle. The diagonal of a rectangle can be found using the Pythagorean theorem.
Given:
- The length of the rectangle (one side) = 24 cm
- The height of the rectangle (other side) = 7 cm
The formula for the diagonal [tex]\( d \)[/tex] is:
[tex]\[ d = \sqrt{(length)^2 + (height)^2} \][/tex]
Substituting the given values:
[tex]\[ d = \sqrt{24^2 + 7^2} \][/tex]
[tex]\[ d = \sqrt{576 + 49} \][/tex]
[tex]\[ d = \sqrt{625} \][/tex]
[tex]\[ d = 25 \, \text{cm} \][/tex]
So, the maximum width of the mail slot is 25cm.

Marisol and Mimi walked the same distance from their school to a shopping mall. Marisol walked 2 miles per hour, while Mimi left an hour later and walked 3 miles per hour. If they reached the mall at the same time how far is the mall from their school?
Answers
The distance walked by Marisol=speed*time=2t
Distance walked by Mimi=3(t-1)
When they've reached school they've all walked the same distance so:
3(t-1)=2t
3t-3=2t
3t-2t=3
t=3
Thus the distance from the mall to their school is 2t=2*3=6 miles
Rex painting the garage in the shed he uses 3 gallons of paint on the garage he uses 3/4 of that amount on the shed enter the amount of paint in gallons Rex uses on the shed
Answers
0.75×(3 gallons) = 2.25 gallons
Rex uses 2.25 gallons of paint on the shed.
Rex uses 2.25 gallons of paint on the shed, which is [tex]\( \frac{3}{4} \)[/tex] of the 3 gallons of paint he uses on the garage.
To find out how much paint Rex uses on the shed, we need to calculate [tex]\( \frac{3}{4} \)[/tex] of the amount of paint he uses on the garage.
Rex uses 3 gallons of paint on the garage.
Therefore, the amount of paint he uses on the shed is:
Paint used on the shed = [tex]\frac{3}{4} \times 3[/tex]
Calculating this:
Paint used on the shed = [tex]\frac{3 \times 3}{4}[/tex]
= [tex]\frac{9}{4}[/tex]
= 2.25
So, Rex uses 2.25 gallons of paint on the shed.

What is the perimeter of the rectangle? Write your answer in scientific notation. The area is 2.76 x 10 pw12 the width is 4.6 x 10 pw5 pw is the power
Answers
You have
area = 2.76·10^12
width = 4.6·10^5
You want to find the perimeter of the rectangle with these dimensions.
The perimeter of a rectangle is twice the sum of length and width.
perimeter = 2*(length + width)
The length can be figured from the area using the formula for area.
area = length*width
area/width = length . . . . . . . . . divide by width
Filling in the numbers, we have
perimeter = 2*((2.76·10^12)/(4.6·10^5) +(4.6·10^5))
perimeter = 2*(6.0·10^6 +0.46·10^6)
perimeter = 2*6.46·10^6 = 1.292·10^7
The perimeter of the rectangle is ...
1.292·10^7
To calculate the perimeter of a rectangle in scientific notation, divide the given area by the width to find the length, then use the perimeter formula (P = 2×length + 2×width), accounting for the power of 10 in your calculations to maintain proper notation.
Explanation:The perimeter of a rectangle can be found using the formula P = 2×length + 2×width. Given the area of the rectangle (2.76 x 10^12 square units) and the width (4.6 x 10^5 units), we can find the length by dividing the area by the width. The length would therefore be the area divided by the width which is (2.76 x 10^12) / (4.6 x 10^5) = 6 x 10^6 units. Now that we have the length and width, we can calculate the perimeter by substituting into the formula: P = 2×(6 x 10^6) + 2×(4.6 x 10^5) = 1.2 x 10^7 + 9.2 x 10^5. Converting the width to the same power of 10, we get P = 1.2 x 10^7 + 0.092 x 10^7 = 1.292 x 10^7 units. This expresses the perimeter in scientific notation.
If Dr. Suzuki rides his bike to his office, he averages 9 miles per hour. If he drives his car, he averages 27 miles per hour. His time driving is one third hour less than his time bicycling. How far is his office?
Answers
Riding speed = 9 mph
Driving speed = 27 mph
Time
If x hours is the time taken when riding, (x - 1/3) hours is the time taken when driving.
Distance in both instances is the same, D= Speed * time
Therefore,
9*x = 27(x-1/3)
9x = 27x - 27/2
9x = 27x - 9
(9-27)x = -9
-18x = -9
x = 9/18 = 1/2 hours
Distance, D = 1/2 *9 = 4.5 miles

Michelle collects US, Canadian and Mexican stamps. In her collection 80% of the stamps are U.S. and Mexican stamps. there are 3 times as many U.S. stamps as Mexican stamps. WHat percent of Michelle's collections is made up of U.S. stamps?
Answers
The US stamps are 3 times the Mexican stamps. That means that of the 80%, Mexicans comprised of the 20% and US comprised of the 60% to satisfy the relationship of their ratios.
Therefore, 60% of Michelle's collection is made up of US stamps.
Final answer:
Michelle's stamp collection consists of 60% U.S. stamps, determined by solving equations based on the given information that U.S. and Mexican stamps make up 80% of her collection and there are three times as many U.S. stamps as Mexican stamps.
Explanation:
The student asked what percent of Michelle's stamp collection is made up of U.S. stamps if 80% are U.S. and Mexican stamps and there are 3 times as many U.S. stamps as Mexican stamps. To solve this, let's call the percentage of U.S. stamps 'U' and the percentage of Mexican stamps 'M'. According to the given information, U + M = 80%, and U = 3M.
We substitute the second expression into the first to get 3M + M = 80%, which simplifies to 4M = 80%. Dividing both sides by 4 gives M = 20%. As the number of U.S. stamps is three times the number of Mexican stamps, we calculate U as 3 × 20% = 60%. So, the percentage of U.S. stamps in Michelle's collection is 60%.

you have $120 to donate equally to several charities. Does this situaton represent direct or inverse variation? Explain.
Answers
The difference between direct and inverse variation is in direct variation, as one variable goes up the other does too, while in inverse, as one variable goes up the other falls.
In this case, as you donate to more charities, the amount you donate to each charity falls, because you donate an equal amount. This means it's inverse variation.

How many gallons of punch will sadie make?
Answers
Sadie will make 3 gallons of punch.
First, let's convert all the measurements to the same unit, such as gallons.
1 gallon = 4 quarts
1 gallon = 8 pints
1 gallon = 16 cups
Now, let's convert each ingredient:
1. Lemon-lime juice: 8 quarts = 8/4 = 2 gallons
2. Vanilla ice cream: 4 pints = 4/8 = 0.5 gallons
3. Orange juice: 8 cups = 8/16 = 0.5 gallons
Now, let's sum up the amounts of each ingredient:
2 gallons (lemon-lime juice) + 0.5 gallons (vanilla ice cream) + 0.5 gallons (orange juice) = 3 gallons
Complete question: Using 8 quarts lemon-lime juice , 4 pints vanilla ice cream , 8 cups orange juice .How many gallons of punch will Sadie make?
