Mrs. Fry has 5 children their ages are 5,
10, 12, 15, and 8. What is the mean
age of her children?
Answer:
The mean of the ages of the Fry children is 8.
Step-by-step explanation:
To find the mean, you add up all of the numbers given, and then divide the sum by how many numbers you are given.
5+10+12+15+8 = 40 40/5 = 8
Ileana buys a large circular pizza that is divided into eight equal slices. She measures along the outer edge of the crust from one piece and finds it to be 512 inches. What is the diameter of the pizza to the nearest inch? A.4 in. B.7 in. C.8 in. D.14 in.
Answer:
14 inches
Step-by-step explanation:
She measures along the outer edge of the crust from one piece and finds it to be 5.5 inches.
We need to find the diameter of the pizza. A pizza is divided into 8 equal parts.
The circumference of one part = [tex]\dfrac{2\pi r}{8}=\dfrac{\pi r}{4}[/tex]
So,
[tex]\dfrac{\pi r}{4}=5.5\\\\2r=D=14\ inch[/tex]
So, the diameter of the pizza is 14 inches.

Lola measures the heights and arm spans of the girls on her basketball team.
She plots the data and makes a scatterplot comparing heights and arm
spans, in inches. Lola finds that the trend line that best fits her results has the
equation y = x + 2. If a girl on her team is 65 inches tall, what should Lola
expect her arm span to be?

Negative, because the products (3)(−25) and (7)(−24) are negative, and the product of two negative numbers is negative
Positive, because the products (3)(−25) and (7)(−24) are negative, and the product of two negative numbers is positive
Answer:
Positive, because the products (3)(−25) and (7)(−24) are negative, and the product of two negative numbers is positive
Determine the solution to the following system of equations.
y = -2x2 + 4x + 8
y = -4x + 16
Answer: (2, 8)
Since both equations in the system are equal to y, substitute -4x + 16 for y in the quadratic equation, and then solve for x as follows.
Next, substitute x = 2 into either of the original equations to find the y-value of the solution to the system of equations.
Therefore, the solution to the given system of equations is (2,8).
The solution of the system of equations will be;
⇒ x = 2
⇒ y = 8
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The system of equations are,
⇒ y = - 2x² + 4x + 8
⇒ y = - 4x + 16
Now,
Since, The system of equations are,
⇒ y = - 2x² + 4x + 8 ..(i)
⇒ y = - 4x + 16 ..(ii)
Substitute the value of y from (ii) in equation (i), we get;
⇒ - 4x + 16 = - 2x² + 4x + 8
⇒ - 2x² + 4x + 8 + 4x - 16 = 0
⇒ - 2x² + 8x - 8 = 0
⇒ - x² + 4x - 4 = 0
⇒ x² - 4x + 4 = 0
⇒ x = - (-4) ± √ (-4)² - 4×1×4 / 2×1
⇒ x = 4 ± √16 - 16 / 2
⇒ x = 4 / 2
⇒ x = 2
And, y = - 4x + 16
⇒ y = - 4 × 2 + 16
⇒ y = - 8 + 16
⇒ y = 8
Thus, The solution of the system of equations will be;
⇒ x = 2
⇒ y = 8

Shawn earns $250 per week grooming animals Write an algebraic expression to represent the amount of money that Shawn earns
Answer [tex]m=250w[/tex]
Step-by-step explanation:
To write an engebraic expression, you should first start off by defining the variables.
Money earned = m
Weeks = w
Next, you have to define the relationship.
Shawn earns $250 per week, so in 2 weeks, he will earn 500, 3 weeks, 750, and so on. I did this by mulitplying, so amount of weeks times the amount of money earned would equal the total money he earned over "w" amount of weeks.
To create the expression, you just have to put the numbers and variables together.
m (money earned over "w" weeks) = 250 (money per week) w (number of weeks).
m=250w

How do I complete this chart?
Answer:
Step-by-step explanation:
You would first have to plug in for x, (which is already given). After plugging in for x, you would need to solve the equation to get y.
Once you have both x and y, you will have your (x,y)
For example: (given x value = -5)
[tex]f(x) = -|x - 5| -4\\f(-5) = -|(-5) - 5| - 4\\f(-5) = -|-10| - 4\\f(-5) = -10 - 4\\f(-5) = -14\\f(-5) = y = -14\\\\[/tex]
so:
x = -5
y = -14
( -5, -14)
find the volume of the composite figure
39in³ is a required volume.
Solution given:
for upper one
length[l]=8in
breadth[b] =3in
height[h]=1in
now
volume [V1]=l×b×h=8×3×1=24in³
again for lower one:
length[l]=6-1=5in
breadth[b] =3in
height[h]=1in
volume [V2]=l×b×h=5×3×1=15in³
Again
total volume =V1+V2=24in³+15in³=39in³
f(x)= 3x - 5x + 2x – 3

Answer: 1914 sq. ft
Step-by-step explanation:
area of circle= pi x radius squared
=3.14 x 10^2
=3.14x100
=314
area triangle= 1/2 base x height
=1/2(20x60)
= 1/2(1200)
= 600
area of rectangle= length x width
=50 x 20
= 1000
add the totals 1000 + 600 + 314=1914 sq. ft.

Answer:
1) B. similar
2) D. (4, 2)
Step-by-step explanation:
1)
When a figure is dilated, the shapes will be similar. Reflected is another transformation so that's wrong. Same size and congruent is wrong since that would have to make the dilated size equal which can't since it's contradicting.
2)
B: (4, -2)
Reflection across the x-axis:
(x, y) → (x, -y)
(4, -2) → (x, -y)
(4, 2)
