Answer:
BC=2
Step-by-step explanation:
The equation is
AB+BC+CD=21
7+BC+12=21
19+BC=21
BC=21-19
BC=2
Answer:
Bc = 2
Step-by-step explanation:
Just add AB + CD
you'll get 19
substract it from AD
21 - 19 = 2
In Above question b = 39°

Given m∥n, find the value of x.
Answer:
x = 20
Step-by-step explanation:
The 2 given angles are alternate interior angles and are congruent, thus
7x - 3 = 6x + 17 ( subtract 6x from both sides )
x - 3 = 17 ( add 3 to both sides )
x = 20
• When volleyballs are purchased, they are not fully inflated. A partially inflated
volleyball can be modeled by a sphere whose volume is approximately 180 in). After
being fully inflated, its volume is approximately 294 in. To the nearest tenth of an
inch, how much does the radius increase when the volleyball is fully inflated?
Answer:
The radius increase when the volleyball is fully inflated is 0.5
Step-by-step explanation:
Volume of Partially inflated volleyball = 180 in³
Volume of Full inflated volleyball = 294 in³
We need to find how much does the radius increase when the volleyball is fully inflated?
First we will find the radius of both Partially inflated and Full inflated volleyball. Then we will find increase in radius.
The formula for Volume of sphere is: [tex]Volume=\frac{4}{3}\pi r^3[/tex]
Finding Radius of Partially inflated volleyball
Volume = 180
Putting values and finding radius of Partially inflated volleyball
[tex]Volume=\frac{4}{3}\pi r^3\\180=\frac{4}{3}*3.14*r^3\\4.186r^3=180\\r^3=\frac{180}{4.186}\\r^3=43.0\\Taking\:cube\:root\:on\:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{47}\\r= 3.6[/tex]
So, radius of Partially inflated volleyball is r = 3.6
Finding Radius of Fully inflated volleyball
Volume = 294
Putting values and finding radius of Fully inflated volleyball
[tex]Volume=\frac{4}{3}\pi r^3\\294=\frac{4}{3}*3.14*r^3\\4.186\:r^3=294\\r^3=\frac{294}{4.186}\\r^3=70.23\\Taking\:cube\:root\:on\:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{70.23}\\r= 4.1[/tex]
So, radius of Partially inflated volleyball is r = 4.1
Now, finding increase in radius by subtracting radius of fully inflated volleyball with partially inflated volleyball
Increase in radius of Fully inflated volleyball = 4.1 - 3.6
Increase in radius of Fully inflated volleyball = 0.5
So, the radius increase when the volleyball is fully inflated is 0.5

The number of machine parts produced at a manufacturing plant is based on the number of parts made in a given day
and the number of hours worked. Let P = 14x + 100 give the number of parts that are produced since the start of the
shift and H = x be the number of hours that are to be worked that particular day. Create the equation that would give
the number of parts produced per hour.
Answer:
The equation that would give the number of parts produced per hour, [tex]P_H[/tex] is given as follows;
[tex]P_H[/tex] = P/H - 100/H
Step-by-step explanation:
The given parameters are;
The number of parts produced is given by the equation, P = 14·x + 100, where x represents the number of hours worked on a particular day
The number of hours worked = H
Therefore, we have;
P = 14·H + 100
At H = 0, P₀ = 100
At H = 1, P = 114
At H = 2, P = 128
Therefore, the rate of change of the number of parts produced with the number of hours spent = The number of parts produced per hour, ΔP/ΔH = [tex]P_H[/tex], is given as follows;
ΔP/ΔH = [tex]P_H[/tex] = (P - P₀)/(H - 0) = P/H - P₀/H = (128 - 100)/(2 - 0) = 14
∴ The number of parts produced per hour, [tex]P_H[/tex] = P/H - 100/H.
-3x-5<10 Equations
Answer:
x>-5
Step-by-step explanation:
First, we need to isolate the variable. To start doing this we can add five to both sides. We now have -3x<15. We then have to divde by -3. When working with inequalites you flip the inequality sign when dividing by a negative number. That then leaves us without answer, x>-5.

A repairman charges an inspection fee plus $16 per hour. A customer with a coupon for 30% off the inspection fee pays $74 for a 2-hour repair. How many hours are worked when a customers pays $124 without a coupon?
Answer:
I want to say that the hours worked was 4. I hope that is right.
Step-by-step explanation:
30% off of $60 is 42
16*2=32 and 32+42=74
124-60=64
16*4=64
so he would have worked 4 hours for $64 and a fee of $60
64+60= 124

At a party there are 3 pizzas to share. If each pizza has 8 slices, determine how many pieces each child will receive if 12 kids attend the party. Now what if 8 kids attend?
Answer: your answer is 3
Step-by-step explanation: if you multiply 3 and 8 you get 24 divide that by 8.
The number of pizzas each kid will receive if there were 12 children was 2 slices each
The number of pizzas each kid will receive if there were 8 children was 3 slices each
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The total number of pizzas at the party = 3 pizzas
The total number of slices in 1 pizza = 8 slices
So , the number of slices in 3 pizzas = 3 x 8 slices
The number of slices in 3 pizzas = 24 slices
Now , the equation will be
The number of children attended the party be = A
The value of A = 12 children
So , the number of pizza slices each child gets = number of slices in 3 pizzas / number of children attended the party
Substituting the values in the equation , we get
Number of pizza slices each child gets = 24 / 12
Number of pizza slices each child gets = 2 slices each
Therefore , if there are 12 children , the number of slices of pizzas each child receives is 2 slices
Now , if the number of children is B = 8
Number of pizza slices each child gets = 24 / 8
Number of pizza slices each child gets = 3 slices each
Therefore , if there are 8 children , the number of slices of pizzas each child receives is 3 slices
Hence , The number of pizzas each kid will receive if there were 12 children was 2 slices each
The number of pizzas each kid will receive if there were 8 children was 3 slices each

Find the mean of the following set of numbers:
8.9, 6.1, -4.8, 8.2, 2.7,-0.1
Enter the answer
Answer:
The mean of the given set of numbers is 3.5
Step-by-step explanation:
We need to find the mean of following numbers:
8.9, 6.1, -4.8, 8.2, 2.7,-0.1
For calculating the mean the formula used is: [tex]Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}[/tex]
Finding sum of numbers:
[tex]Sum \ of \ numbers= 8.9+6.1-4.8+8.2+2.7-0.1\\Sum \ of \ numbers= 21[/tex]
Total numbers = 6
So, mean is:
[tex]Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}\\Mean=\frac{21}{6}\\Mean= 3.5[/tex]
So, mean of the given set of numbers is 3.5

Kelly purchased 5 containers of ice cream for a party. Each container holds 8 cups of ice cream. Before the party, her brother ate 2 cups of ice cream. If one serving of ice cream is 23 of a cup, how many servings of ice cream will be left for the party?
Given:
Kelly purchased 5 containers of ice cream for a party.
Each container holds 8 cups of ice cream.
Her brother ate 2 cups of ice cream.
One serving of ice cream = 2/3 of a cup.
To find:
Number of servings of ice cream will be left for the party?
Solution:
We have,
1 container = 8 cups of ice cream
5 containers = 5×8 = 40 cups of ice cream
Her brother ate 2 cups of ice cream. So, remaining cups of ice cream is
[tex]40-2=38[/tex] cups
Now,
[tex]\dfrac{2}{3}[/tex] of a cup = 1 serving
1 cup = [tex]\dfrac{3}{2}[/tex] serving
38 cup = [tex]38\times \dfrac{3}{2}[/tex] serving
= [tex]19\times 3[/tex] serving
= 57 serving
Therefore, 57 servings of ice cream will be left for the party.
