Determine the diameter of a curcle with the radius 12.2
Answer:
24.4
Step-by-step explanation:
diameter=2*radius
=2*12.2
=24.4
Final answer:
The diameter of a circle with a radius of 12.2 is 24.4 units. This is calculated by doubling the radius, using the formula D = 2r.
Explanation:
To determine the diameter of a circle with a radius of 12.2, you simply need to use the relationship between the radius and the diameter of a circle. The diameter is twice the radius, which can be represented by the formula D = 2r, where D is the diameter and r is the radius.
Substituting the value of the radius into the formula gives us:
D = 2 × 12.2
This calculates to:
D = 24.4
Therefore, the diameter of the circle is 24.4 units. Keep in mind that if the radius was given in a specific unit, like meters or centimeters, then the diameter will be in the same unit.

A party rental company has chairs and tables for rent. The total cost to rent 3 chairs and 2 tables is $22. The total cost to rent 5 chairs and 6 tables is $60. What is the cost to rent each chair and each table?
Answer:
The cost to rent each chair and each table are $1.5 and $8.75 respectively
Step-by-step explanation:
Let x represent 1 chair
Let y represent 1 table
Therefore
3x + 2y = 22 ------------(1)
5x + 6y = 60 ------------(2)
Multiply (1) by 5 and (2) by 3
15x + 10y = 110 ----------(3)
15x + 18y = 180 ------------(4)
Subtract (3) from (4)
8y = 70
Divide through by 8
y = $8.75
Substitute y = 8.75 in (1)
3x + 2y = 22
3x + 2(8.75) = 22
3x + 17.5 = 22
Collect like terms
3x = 22 - 17.5
3x = 4.5
Divide through by 3
x =$1.5
Final answer:
By setting up a system of linear equations based on the given information and solving it, we determined that the cost to rent each chair is $1.50 and the cost to rent each table is $8.75.
Explanation:
To find the cost to rent each chair and each table from the party rental company, we set up a system of linear equations based on the information given:
3 chairs and 2 tables cost $22.5 chairs and 6 tables cost $60.Let C be the cost of one chair and T be the cost of one table. We can write the following equations:
3C + 2T = $225C + 6T = $60Solving this system of equations, we can find the values of C and T. First, multiply the first equation by 3 to eliminate T:
(3C + 2T) * 3 = 22 * 39C + 6T = $66Now we can subtract the second equation from the modified first equation:
9C + 6T - (5C + 6T) = $66 - $604C = $6C = $1.50With the cost of a chair known, we can substitute back into either equation to find the cost of a table:
3(1.50) + 2T = $224.50 + 2T = $222T = $22 - 4.502T = $17.50T = $8.75The cost to rent each chair is $1.50 and the cost to rent each table is $8.75.

To find four decimals whose sum is 2.35, you can set up a system of equations and solve for the values. The four decimals are 0.10, 0.20, 0.15, and 0.15.
Explanation:The question is asking for four decimals whose sum is 2.35. To find these decimals, we can assign variables to each decimal (let's call them a, b, c, and d) and set up an equation: a + b + c + d = 2.35. Since we want the decimals to have only two places after the decimal point, we can express them in hundredths. For example, instead of 0.1, we can write it as 10/100 = 0.10.
Now, we can set up a system of equations:
a + b + c + d = 2.35
a = 10/100
b = 20/100
c = 15/100
d = 15/100
By substituting the values back into the first equation, we have: (10/100) + (20/100) + (15/100) + (15/100) = 2.35. Simplifying the equation, we have 0.10 + 0.20 + 0.15 + 0.15 = 0.60. Therefore, the four decimals whose sum is 2.35 are 0.10, 0.20, 0.15, and 0.15.

The length of DZ is 4 units ⇒ 3rd answer
Step-by-step explanation:
Triangle X Y Z is cut by line segment C D, where
C lies on side XY and D lies on the side YZThe length of C D is 15The length of X Z is 18The length of C Y is 25The length of Y D is 20C D and X Z are parallelCX = 5 unitsWe need to find the length of DZ
In Δ XYZ
∵ C ∈ XY and D ∈ YZ
∵ CD // XZ
∴ m∠YCD = m∠YXZ ⇒ alternate angles
∴ m∠YDC = m∠YZX ⇒ alternate angles
In Δs YCD and YXZ
∵ m∠YCD = m∠YXZ
∵ m∠YDC = m∠YZX
∵ ∠Y is a common angle
∴ Δ YCD is similar to Δ YXZ by AAA postulate
- There is a constant ratio between their corresponding sides
∴ [tex]\frac{YC}{YX}=\frac{CD}{XZ}=\frac{YD}{YZ}[/tex]
∵ YC = 25 units
∵ CX = 5 units
∵ YX = YC + CX
∴ YX = 25 + 5 = 30 units
∵ YD = 20 units
∵ YZ = YD + DZ
∴ YZ = 20 + DZ
Let us use the ratio of the corresponding side
∵ [tex]\frac{YC}{YX}=\frac{YD}{YZ}[/tex]
∴ [tex]\frac{25}{30}=\frac{20}{20+DZ}[/tex]
- Simplify [tex]\frac{25}{30}[/tex] by dividing up and down by 5
∵ [tex]\frac{25}{30}=\frac{5}{6}[/tex]
∴ [tex]\frac{5}{6}=\frac{20}{20+DZ}[/tex]
- By using cross multiplication
∴ 5(20 + DZ) = 6(20)
∴ 100 + 5 DZ = 120
- Subtract 100 from both sides
∴ 5 DZ = 20
- Divide both sides by 5
∴ DZ = 4 units
The length of DZ is 4 units

What is a equal to?
12=2a
Using the balance method, we find a = 15 by isolating the variable a. Substituting a = 15 back into the original equation, we verify the solution.
To solve the equation 12 = 2a - 18 using the balance method, we aim to isolate the variable a on one side of the equation.
Starting with 12 = 2a - 18, we'll first add 18 to both sides to isolate the term with 2a:
[tex]\[12 + 18 = 2a - 18 + 18\]\[30 = 2a\]\\[/tex]
Next, we divide both sides by 2 to solve for a:
[tex]\[\frac{30}{2} = \frac{2a}{2}\]\[15 = a\][/tex]
Now, let's verify the solution by substituting a = 15 back into the original equation:
[tex]\[12 = 2(15) - 18\]\[12 = 30 - 18\]\[12 = 12\][/tex]
Since the left side equals the right side, the solution a = 15 is verified.

1 a. Noah rides his bike with a constant
speed of 18 km/h. How long will he
take to travel a distance of
54 kilometers?
Answer:
3 hours
Step-by-step explanation:
Recall:
Distance = speed x time
we are given that speed = 18 km/h and distance = 54 km.
hence,
54 = 18 x time (divide both sides by 18 and rearrange)
time = 54/18 = 3 hours
Noah will take 3 hours to travel a distance of 54 kilometers at a constant speed of 18 km/h.
To determine how long Noah will take to travel a distance of 54 kilometers at a constant speed of 18 km/h, we can use the formula for time, which is:
Time = Distance / Speed
Let's calculate Noah's travel time:
Time = 54 km / 18 km/h = 3 hours
Noah will take 3 hours to cover the 54-kilometer distance on his bike.

• They must produce at least 10 and not more than 30 graphing calculators per day.
• Each day, the number of graphing calculators cannot exceed twice the number of scientific calculators produced.
• The number of scientific calculators cannot exceed 40 per day.
If x is the number of graphing calculators produced daily and y is the number of scientific calculators produced daily, what are the constraints ?
10 ≤ x ≤ 30, x < 2y, x < 40.
Solution:
Given x is the number of graphing calculators produced daily and
y is the number of scientific calculators produced daily.
Step 1: A company produce atleast 10 and not more than 30 graphing calculators per day.
⇒ 10 ≤ x < 30
Step 2: Each day, the number of graphing calculators cannot exceed twice the number of scientific calculators produced.
⇒ x < 2y
Step 3: The number of scientific calculators cannot exceed 40 per day.
⇒ x < 40
Hence, the constraints are 10 ≤ x ≤ 30, x < 2y, x < 40.

There are 1160 pennies and 114 dimes in the piggy bank.
Step-by-step explanation:
Given,
Worth of money = $23.00 = 23*100 = 2300 cents
1 penny = 1 cent
1 dime = 10 cents
Let,

Final answer:
Joshua has 114 dimes and 1160 pennies in his piggy bank. This was determined by setting up a system of equations based on the values of the coins and the given relationship between the number of dimes and pennies.
Explanation:
The problem presented is a typical algebraic word problem that requires setting up equations based on the given information about dimes and pennies. We are told that the total value of the coins is $23.00 and that the number of pennies is 20 more than 10 times the number of dimes. To solve the problem, we need to use the fact that the value of a dime is 10 pennies, and then set up a system of linear equations to find the number of each type of coin.
Step-by-Step Explanation
Let's denote the number of dimes as d and the number of pennies as p.The value of the dimes is 10d pennies since each dime is worth 10 pennies.The total value of the dimes and pennies is 23 dollars or 2300 pennies (since 1 dollar equals 100 pennies).According to the problem, p = 10d + 20.The equation representing the total value is thus 10d + p = 2300.Substituting p from the first equation into the second gives us: 10d + (10d + 20) = 2300.Simplifying this equation, we get 20d + 20 = 2300.Subtracting 20 from both sides, we get 20d = 2280.Dividing both sides by 20, we find out that d = 114.Substituting d back into the first equation to find p, p = 10(114) + 20 which gives us p = 1160.Thus, Joshua has 114 dimes and 1160 pennies in his piggy bank.

A group of 20 people from the retirement community is visiting the fair today. Each person is between 75 and 79 years old and will participate in either the Pie Eating Contest or the Chili Cookoff. If all 20 people joined the same event, how would the shape of the histogram change compared to the original?
Histogram with title Pie Eating Contest, horizontal axis labeled Age Group (year) with bins 0 to 19, 20 to 39, 40 to 59, and 60 to 79 and vertical axis labeled Number of People with values from 0 to 60 at intervals of 10. The first bin goes to 20, the second goes to 40, the third goes to 60, and the last goes to 50. Histogram with title Chili Cookoff, horizontal axis labeled Age Group (year) with bins 0 to 19, 20 to 39, 40 to 59, and 60 to 79 and vertical axis labeled Number of People with values from 0 to 60 at intervals of 10. The first bin goes to 30, the second goes to 50, the third goes to 40, and the last goes to 10.
The Chili Cookoff would be more skewed.
The Pie Eating Contest would be more skewed.
The Chili Cookoff would be less symmetrical.
The Pie Eating Contest would be more symmetrical.
Answer:
The Pie Eating Contest would be more skewed.
Step-by-step explanation:
In order to answer this, first we need to draw original histograms for both of these two events. Since all of the 20 people from the retirement community is attending one of the events, but we don't know which one, we need to draw new histograms for each of the events (see the attachment).
The only distinction of new histograms is the change in the fourth bin representing the 60-79 age group, since all visitors from retirement community fall into this age group.
A histogram is symmetrical if, when split in half by a vertical line, its left and right half act approximately as an object and its reflection in the mirror.
A histogram is skewed if, when split in half by a vertical line, one of its halves shows much greater values then the other.
So looking at our histograms, if all 20 people went to a Pie Eating Contest, that histogram would become more skewed and if all 20 people went to a Chili Cookoff, that histogram would become more symmetrical, which makes b) the correct answer.
Based on the information given, the correct option is B. The Pie Eating Contest would be more skewed.
From the information given, it was stated that a group of 20 people from the retirement community is visiting the fair today and that each person is between 75 and 79 years old and will participate in either the Pie Eating Contest or the Chili Cookoff.In a situation where all the 20 people joined the same event, the shape of the histogram will change compared to the original as the pie-eating contest would be more skewed.This implies that when split in half by a vertical line, one of its halves will have greater values than the other.

O y=(2]*_3
Answer:
The function given by [tex]y = - (2)^{x} + 3[/tex] will have a range of y < 3.
Step-by-step explanation:
The function given by [tex]y = - (2)^{x} + 3[/tex] will have a range of y < 3.
This is because, for any real values of x, the term [tex]- (2)^{x}[/tex] will have a negative value. If we put x = 1, then, [tex]- (2)^{x}[/tex] = - 2, and for x = -1, then [tex]- (2)^{x}[/tex] = - 0.5.
That means [tex]- (2)^{x} < 0[/tex] for all real x.
Hence, [tex]- (2)^{x} + 3[/tex] < 0 + 3
⇒ y < 3 for all real x. (Answer)
