A contractor is building the base of a circular fountain. On the blueprint, the base of the fountain has a diameter of 18 centimeters. The blueprint has a scale of three centimeters to four feet. What will be the actual ares of the base of the fountain, in square feet, after it is built? Round your answer to the nearest tenth of a square foot.
Answer:
452.4 square feet
Finding the diameter:
Since there are 3 centimeters for every 4 feet, we need to divide 18 by 3
18 ÷ 3 = 6 which means the ratio is scaled up by 6 so we multiply 4 by 6
4 · 6 = 24 that means that the diameter of the base of the fountain is 24 feet
Finding the area:
Since the area of a circle is πr² we need to divide the diameter by 2 to get the radius(r)
24 ÷ 2 = 12 now we need to square 12 (which is multiplying it to itself ex. 5² is 5 · 5)
12 · 12 = 144 now we multiply it by π
π · 144 ≈ 452.38934 lastly we round it
452.4 square feet

A store regularly sells a Nintendo Switch Lite for $200. They are currently on sale for 30% off and in your state the sales tax is 8%. What would be the final cost for the consumer (including tax) if they buy the Nintendo Switch Lite?
Answer:
$151.20
Step-by-step explanation:
The sale price of the Nintendo Switch Lite is 30% off its regular price of $200, which means the discount is:
Discount = 30% x $200 = $60
The sale price of the Nintendo Switch Lite after the discount is:
Sale price = $200 - $60 = $140
The sales tax in the state is 8%, so the tax amount on the sale price is:
Tax amount = 8% x $140 = $11.20
Therefore, the final cost for the consumer, including tax, would be:
Final cost = Sale price + Tax amount = $140 + $11.20 = $151.20
Hence, the final cost for the consumer, including tax, would be $151.20 if they buy the Nintendo Switch Lite.
Grayson created a scale drawing of the school multipurpose room in his art class. In the scale drawing, the length of the room is 14 inches. The length of the actual multipurpose room is 112 feet.
The scale that Grayson use to create the scale drawing of the school multipurpose room is 1 inche: 8 feet
Which scale did Grayson use to create the scale drawing of the school multipurpose room?From the question, we have the following parameters that can be used in our computation:
In the scale drawing, the length of the room is 14 inches. The length of the actual multipurpose room is 112 feet.Using the above as a guide, we have the following:
Scale factor = scale length : actual length
substitute the known values in the above equation, so, we have the following representation
Scale factor = 14 in : 112 feet
Evaluate
Scale factor = 1 inches : 8 feet
Hence, the scale factor is 1 inches : 8 feet

The original price of a shirt is $30. The sale price of the shirt is 20% off of the original price. Sales tax is 7% of the sale price of the shirt. The total cost of the shirt is the sale price plus sales tax. A customer buys the shirt on sale. What is the total cost to the customer?
A. $25.68
B. $17.00
C. $10.70
D. $6.42
Answer:
$25.68
Sales Price:
In order to find the sales price we need to find what 20% off of $30 is. 20% off is 80% of the original price so we'll use 80% instead. Now what we need to do to find 80% of $30 is we need to multiply $30 by 0.8. When you're converting precents to decimals you move the decimal place over 2 spots like this: 38.0% = 0.38. Okay, now that we've figured that out we can do the multiplication:
$30 · 0.8 = $24
Sales Tax:
Now there are 2 ways to go from here:
1. Multiply $24 by 7% then add it to $24
This is the first solution to come to mind but is inefficient
2. Multiply $24 by 107%
You skip the second step by adding $24 in the percent (since $24 is 100% in this case).
Either way you come to the conclusion of $25.68

Caden is making beaded necklaces. Blue and red are his favorite colors, so he buys 50 grams of beads in each color. He switches between the two colors, but he runs out of the red beads first. That makes him wonder how much heavier the red beads are than the blue ones. After counting them, he finds he bought 250 blue beads but only 200 red beads. How many milligrams heavier is a red bead than a blue bead?
Since Caden bought 50 grams of each color and all the blue beads weigh the same and all the red beads weigh the same, we can divide 50 by the number of blue beads to find the weight of a single blue bead:
50 grams / 250 beads = 0.2 grams per blue bead
Similarly, we can divide 50 by the number of red beads to find the weight of a single red bead:
50 grams / 200 beads = 0.25 grams per red bead
To find the weight difference between a red bead and a blue bead, we can subtract the weight of a blue bead from the weight of a red bead:
0.25 grams per red bead - 0.2 grams per blue bead = 0.05 grams per bead
To convert grams to milligrams, we can multiply by 1000:
0.05 grams per bead * 1000 = 50 milligrams per bead
Therefore, a red bead is 50 milligrams heavier than a blue bead.

A tree grows 1.5 feet per year. The tree is now 6 feet tall. Which sets of steps show ways to determine how many years the tree will take to be 27 feet tall?
Select the TWO correct answers.
A. 1.5x+6=27
1.5x=21
x=14
The tree will take 14 years to be 27 feet tall.
B. 27-6=21
21÷1.5=14
The tree will take 14 years to be 27 feet tall.
C. 1.5(x+6)=27
x+6=18
x=12
The tree will take 12 years to be 27 feet tall.
D. 1.5x+6=27
x+6=18
x=12
The tree will take 12 years to be 27 feet tall.
E. 27÷1.5=18
18-6=12
Answer:
Step-by-step explanation:
Answers are A and B.
Facts given are :
Current height = 6 ft
Growth per year = 1.5 ft
Final height = 27
Explanation for A:
Assume it takes 'x' number of years.
initial height + growth in 'x' years = Total height of the tree after 'x' years
6 + 1.5x = 27
1.5x = 27 -6 = 21
(1.5 can be written as 3/2) 3x/2 = 21
3x = 42
x = 14
hence, number of years = 14
Explanation for B:
After 'x' years,
Final height - initial height = Growth in 'x' years
27 - 6 = Growth in 'x' years
21=Growth in 'x' years = 1.5x
21= 3x/2
42=3x
14=x
hence, number of years = 14

Clara and her little sister are making kites to fly in the park. Clara ties 60 centimeters of ribbon to the bottom of her little sister's kite. Clara's kite is bigger, so she needs more ribbon than her sister. Clara uses an extra 40 centimeters of ribbon for her own kite. If Clara started with 2 meters of ribbon, how many centimeters does she have left?
Answer:
Clara will have 40 centimeters of ribbon left.
Step-by-step explanation:
1 meter is the same as 100 centimeters, so 2 meters is 200 centimeters. So, we take 200 centimeters, subtract 60 centimeters:
[tex]200 - 60= 140[/tex]
so she has 140 centimeters, then we subtract another 60 centimeters for Clara's kite:
[tex]140 - 60= 80[/tex]
But remember, she needs an extra 40 centimeters because her kite is bigger:
[tex]80 - 40= 40[/tex]
So, Clara is left with 40 centimeters, or 0.4 meters, of ribbon.
A. Plot points that show the volume when r=1, r=2, r=3, and .r=4.
B. Show your reasoning.
To plot points that show the volume of a sphere for different values of the radius, we can use the formula for the volume of a sphere:
V = (4/3)πr^3
For different values of the radius, we can substitute those values into the formula and calculate the corresponding volume.
A. Plotting points for r = 1, 2, 3, and 4:
When r = 1, V = (4/3)π(1)^3 = (4/3)π ≈ 4.19
When r = 2, V = (4/3)π(2)^3 = (4/3)π(8) ≈ 33.51
When r = 3, V = (4/3)π(3)^3 = (4/3)π(27) ≈ 113.1
When r = 4, V = (4/3)π(4)^3 = (4/3)π(64) ≈ 268.1
We can plot these points on a graph with radius on the x-axis and volume on the y-axis:
B. Reasoning:
As we can see from the formula for the volume of a sphere, the volume increases rapidly as the radius increases. In fact, the volume increases with the cube of the radius, which means that a small increase in radius can result in a significant increase in volume. This is why we see such a rapid increase in volume as we increase the radius from 1 to 4.
The graph of the volume of a sphere versus its radius is a curve that starts at zero when the radius is zero (i.e., a point) and increases rapidly as the radius increases. It is a smooth, continuous curve that does not have any sharp turns or corners. This is because the formula for the volume of a sphere is a smooth, continuous function of the radius, with no sudden jumps or changes.
