Answer:
Option C. 154 cm²
Step-by-step explanation:
From the question given above, the following data were obtained:
Pi (π) = 22/7
Diameter (d) = 14 cm
Area (A) =?
Next, we shall determine the radius of the circle. This can be obtained as follow:
Diameter (d) = 14 cm
Radius (r) =?
r = d/2
r = 14/2
r = 7 cm
Finally, we shall determine the area of the circle as illustrated below:
Pi (π) = 22/7
Radius (r) = 7 cm
Area (A) =?
The area of a circle can be obtained by using the following formula:
A = πr²
A = 22/7 × 7²
A = 22/7 × 7 × 7
A = 22 × 7
A = 154 cm²
Thus, the area of the circle is 154 cm²
Answer:
area of circle=π(14/2)²=22/7 ×7²=22×7=154cm²
A band is playing at an auditorium with floor seats and balcony seats. The band wants to sell the floor
tickets for $15 each and balcony tickets for $12 each. They want to make at least $3,000 in ticket sales.
1. How much money will they collect for selling x floor tickets?
2. How much money will they collect for selling y balcony tickets?
Answer:
We know that x is the number of floor tickets they sell, and each one costs $15, then the amount of money they will get by those sells is x times $15, this is:
x*$15.
And y is the number of balcony tickets they sold, each one of these costs $12, then the total amount of money made in those tickets is:
y*$12.
Then the total amount of money that the band made is:
x*$15 + y*$12
And they want to make, at least, $3,000, then we will have the inequality:
x*$15 + y*$12 ≥ $3000
That can´t really be solved, because we have two variables and only one inequality, but this represents the given situation.

Step-by-step explanation:
Given the expression
[tex]-4\left(x\:+\:3\right)\:<\:-2\:-\:2x[/tex]
Expanding
[tex]-4x-12<-2-2x[/tex]
Add 12 to both sides
[tex]-4x-12+12<-2-2x+12[/tex]
[tex]-4x<-2x+10[/tex]
Add 2x to both sides
[tex]-4x+2x<-2x+10+2x[/tex]
[tex]-2x<10[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}[/tex]
[tex]\left(-2x\right)\left(-1\right)>10\left(-1\right)[/tex]
[tex]2x>-10[/tex]
Divide both sides by 2

Let g represent the number of games. Show your work.
i really need an answer!
Answer:
8
Step-by-step explanation:
15 - .75g = 13 - .50g
2 = .25g
8 = g
If Deanna starts with $15, and the machine she is playing costs $0.75 per game. Lulu starts with $13, and her machine costs $0.50 per game.Then after 8 games will the two friends have the same amount of money remaining
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Let g represents game
Deanna starts with $15, and the machine she is playing costs $0.75 per game
So the equation will be
15 -0.75g
Lulu starts with $13, and her machine costs $0.50 per game.
The equation for Lulu will be
13 - 0.50g
Now let us equations of both Deanna and Lulu
15 -0.75g =13 - 0.50g
15-13=0.75g-0.50g
2 = 0.25g
Divide both sides by 0.25
8 = g
Hence after 8 games the two friends have the same amount of money remaining

Solve for x using the vertical angles below:
(2 + 3x)
62
Answer:
20
Step-by-step explanation:
Solving for x using the vertical angles we get , the value of x is: x = 20.
Here, we have,
from the given figure we get,
angle (2 + 3x) and angle62 are opposite angles.
we know that,
When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are always equal to each other.
so, we have,
angle (2 + 3x) = angle62
(2 + 3x) = 62
or, 3x = 60
or, x = 20
Hence, Solving for x using the vertical angles we get , the value of x is: x = 20.

x + y = 5
Answer:
x= -7, y= 12
Step-by-step explanation:
To find the value of x and y, first label the 2 equations.
2x +y= -2 -----(1)
x +y= 5 -----(2)

Mai wants to make a scale drawing of her kitchen. Her kitchen is a rectangle with length 6 m and width 2 m. She decides on a scale of 1 to 40.
Draw and label the dimensions of a scale drawing of Mai’s kitchen, using a scale of 1 to 40. HEEEEEEEELPPPP
Answer:
Length of scale = 15 cm
Width of scale = 5 cm
Step-by-step explanation:
Dimensions of the kitchen of Mai are given as:
Length of kitchen = 6 m
Width of kitchen = 2 m
Scale to be used = 1 to 40
To find:
The drawing with labeling and dimensions of the scale drawing.
Solution:
First of all, let us understand about the concept of scaling.
Scaling is a method to represent big structures on paper.
For this purpose, we decide a scaling factor and draw the big structures on paper by scaling down (making it small) by using a scaling factor.
Here, the scale factor used is 1 to 40.
i.e. 1 unit on scale is equivalent to 40 units on the actual kitchen.
40 units of kitchen = 1 unit of scale
1 unit of kitchen = [tex]\frac{1}{40}[/tex] units of scale
6 m of kitchen = [tex]\frac{1}{40}\times 6\ m = \frac{600}{40}\ cm = 15\ cm[/tex]
Length of scale = 15 cm
40 units of kitchen = 1 unit of scale
1 unit of kitchen = [tex]\frac{1}{40}[/tex] units of scale
2 m of kitchen = [tex]\frac{1}{40}\times 2\ m = \frac{200}{40}\ cm = 5\ cm[/tex]
Width of scale = 5 cm

A. 1 /3
B. 3 /4
C. 1 1/6
D. 1 1/3
Dave's rate of completion is 4/3 walls per hour and this can be determined by using the concept of unit rate.
Given :
Dave is hanging dry wall in a house with square rooms. He completes on average 2/ 3 of a wall in 1/2 of an hour.The following steps can be used in order to determine Dave's rate of completion:
Step 1 - The concept of unit rate can be used in order to determine Dave's rate of completion.
Step 2 - According to the given data, Dave completes on average 2/3 of a wall in 1/2 of an hour.
Step 3 - Now, let Dave's rate of completion be 'x'.
Step 4 - So, the value of 'x' can be calculated as:
[tex]x = \dfrac{\dfrac{2}{3}}{\dfrac{1}{2}}[/tex]
Step 5 - Simplify the above expression.
[tex]x = \dfrac{2}{3}\times\dfrac{2}{1}[/tex]
[tex]\rm x = \dfrac{4}{3}\;walls \;per \;hour[/tex]
Therefore, Dave's rate of completion is 4/3 walls per hour.
