However the formula to find the area of a circle is A=[tex] \pi [/tex]r²
So to convert the 15 in diameter to a radius you have to do 15÷2,which is equal to 7.5
Now we know that the radius is 7.5.
So what we do now is A=[tex] \pi [/tex]7.5²
Then after we find what 7.5² is we get A=[tex] \pi [/tex]56.25
Then what we do is 3.14×56.25, because pi= 3.14.
So when we do 3.14×56.25, we get 176.625
So the answer is A= 176.6 in²

Answers
Answer:
Option A - 2.2
Step-by-step explanation:
Given : Data 7, 2, 8, 5, 9, 9, 5, 6, 8, 1.
To find : What is the mean absolute deviation for these data?
Solution :
Step 1 - Calculate the mean of the data,
[tex]M=\frac{\sum x_n}{n}[/tex]
[tex]M=\frac{7+2+8+5+9 +9+5+6+8+1}{10}[/tex]
[tex]M=\frac{60}{10}[/tex]
[tex]M=6[/tex]
The mean is 6.
Step 2 - Calculate the distance between each data point and the mean.
Data points Distance from mean
7 |7-6| = 1
2 |2-6| = 4
8 |8-6| = 2
5 |5-6| = 1
9 |9-6| = 3
9 |9-6| = 3
5 |5-6| = 1
6 |6-6| = 0
8 |8-6| = 2
1 |1-6| = 5
Step 3 - Add all the terms of distance from mean
X=1+4+2+1+3+3+1+0+2+5=22
Step 4 - Apply mean absolute deviation formula,
[tex]MAD=\frac{\sum X}{n}[/tex]
[tex]MAD=\frac{22}{10}[/tex]
[tex]MAD=2.2[/tex]
Therefore, Option A is correct.
The mean absolute deviation is 2.2.

Find the area of the trapezoid to the nearest tenth.
Answers
However, I will try to help you with the procedures on how to get the area of trapezoid and you can apply on the diagram you have.
Now, area of trapezoid can be calculated using the following rule:
area of trapezoid = [tex] \frac{b1 + b2}{2} * h[/tex]
where:
b1 is the length of the first base
b2 is the length of the second base
h is the height of the trapezoid
The bases are the two parallel sides in the trapezoid
To better illustrate this, consider the attached diagram.
We have:
b1 = 5 m
b2 = 8 m
h is the perpendicular height = 4 m
Area = [tex] \frac{5+8}{2} *4[/tex] = 26 m²

all tickets for a concert are the same price.the ticket agency adds a fixed fee to every order.a person who orders 5 tickets pays $93.a person who buys 3 tickets pays $53
Answers
The question can be solved using a system of linear equations. The price of each ticket is found to be $20, and the fixed fee added by the ticket agency is $13.
Explanation:The subject of this question concerns solving a system of linear equations. Given the two scenarios, buying 5 tickets for $93 and buying 3 tickets for $53, we can represent these as equations where 't' represents the price of a ticket and 'f' represents the fixed fee. The equations thus become:
5t + f = 933t + f = 53
To solve this system of equations, we could subtract the second equation from the first, which would eliminate 'f' and yield an equation only in terms of 't'. This would look like:
2t = 40
From here, we can see that t (the price of each ticket) equals $20. We can then substitute 't' into one of the equations to find the fixed fee 'f', which in this case equals $13.

what is the answer to 5+2x10
Answers
We are given expression : 5+2x10.
It can be read as 5 plus 2 times 10.
Now, we need to see, what operation should carry out first.
Please note: We always follow the order of operations.
The order of operations could be follow by the rule PEMDAS.
It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
We don't have Parentheses, Exponents in the given problem.
So, we would start order of operations: first multiplication and then addition.
So, we need to multiply 2 × 10 first.
2 × 10 = 20.
Now, we need to apply addition operation.
Therefore, 5+2x10 = 5+20.
On adding 5 and 20, we get 25.
So, the final answer is 25.
Answer:
25 (assuming the x means multiplication)
Step-by-step explanation:
Start by using PEMDAS (Parenthesis, exponents, multiplication and division from right to left, addition and subtraction from right to left) you would start with multiplication or 2x10 which is 20 and then you have 5+20 left and that is obviously just 25

Answers
Standard Deviation is a measure of how much the scores vary on average from the mean value. A larger standard deviation signifies that values are away from the mean, a smaller standard deviation shows that the values are close to the mean.
Since the standard deviation of Sam's scores is lower as compared to that of Kristen, we can say that Sam's score were more closer to the mean value and were consistent.

How much sugar is there in 100g of 15% sugar syrup?

In order to solve this problem, we'll need set up a proportion and solve. This is our proportion: x/100 = 15/100. Next, we'll cross-multiply to get: 100x = 1500. Lastly, we'll divide both sides by 100 to figure out how many grams of sugar are in 100g of 15% sugar syrup: x = 15 grams.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
In 100g of 15% sugar syrup, there is 15g of sugar.
Sugar SyrupSugar syrup is a thick viscous liquid that mostly contains water and dissolved sugar in it. therefore, a 20% sugar syrup means having a 20:80 ratio of sugar and water in a unit of sugar syrup.
Given to us,100g of sugar syrup 15% sugar,
Now, 15% of sugar means having a 15:85 ratio of sugar and water in 100g of sugar syrup. Let the sugar in 100g of sugar syrup be x. so, the water in the syrup is (100-x), therefore,
[tex]\bold{\dfrac{15}{85} = \dfrac{sugar}{water}}[/tex]
Substituing the values we get,
[tex]\dfrac{15}{85} = \dfrac{x}{100-x}\\\\15\times(100-x) = 85x\\1500 - 15x = 85x\\1500 = 85x +15x\\1500 = 100 x\\\\x = \dfrac{1500}{100}\\\\x = 15[/tex]
Hence, In 100g of 15% sugar syrup, there is 15g of sugar.

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
In order to solve this we will need the formula that calculates the Area of a Circle. The formula is the following,
[tex]A = \pi r^{2}[/tex]
Where:
A is the area of the circler is the radius of the circleWe are given the diameter of the circle in the question but based on the formula we need the radius. The radius is half of the diameter. Therefore,
[tex]r = 3ft / 2[/tex]
[tex]r = 1.5[/tex]
Now that we have the radius we can plug it into the formula to find the area of the circle.
[tex]A = \pi 1.5^{2}[/tex]
[tex]A = \pi 2.25[/tex]
[tex]A = 7.06 [/tex]
Based on the calculations above we can see that 7.1 [tex]ft^{2}[/tex] (rounded to the nearest tenth) needs to painted

Answer:

Step-by-step explanation:
Two cyclists leave town at the same time on the same road going in the same direction.
Cyclist A is going 6 mph faster than cyclist B
Let speed of cyclist B be x mph
Speed of cyclist A be (x+6) mph
Both cyclist leave town at the same time and traveled 8 hours.
Distance covered by cyclist A in 8 hours= 8(x+6)Distance covered by cyclist B in 8 hours= 8xAfter 8 hours cyclist A has traveled 3 times the distance as cyclist B
Therefore, 8(x+6) = 3(8x)
8x + 48 = 24x
24x - 8x = 48
16x = 48
x = 3 mph
Hence, The speed of cyclist B was 3 mph

Answers
Variable Expenses Total : $5.80
We have been given that Daniel's weekly allowance is $10 and we have to figure out his monthly fixed and variable expenses. To tackle this problem we have to figure out what are fixed expenses and what are variable expenses.
Fixed expenses are not going to vary as they are fixed. We have been given that Daniel has swimming class once a week and pays a $1.50 pool fee. Daniel is also saving for a new swimming trunks and sets aside $2.50 per week.
Variables expenses vary in a given range. We have been given that Daniel sometimes goes out to eat with friends and spends $5 to $10. Daniel goes to a swim meet in another town and spends $3 to $9 on bus fare.
Now let us find monthly fixed expenses first. [tex]1.50+2.50[/tex] are his weekly fixed expenses. To figure out monthly expenses we will multiply weekly expenses by 4 because a month has four weeks.
Monthly fixed expenses=[tex]4\times (1.50+2.50)=4\times 4=16[/tex]$
Now we will figure out monthly variable expenses. We have been given that Daniel has spent $8.50 for lunch and gone for two swim meets costing $7 each.
Monthly variable expenses=[tex]8.50+2\times 7=8.50+14=22.50[/tex]$

Answers
chess club members = computer club members
500 - 30x = 150 + 20x
x represents the amount of years that have passed. The coefficients for x represent the loss or gain of members per year.
Add 30x to both sides.
500 = 150 + 50x
Subtract 150 from both sides.
350 = 50x
Divide both sides by 50 to solve for x.
x = 7
