You are designing a new
movie complex. There are
14 movie theaters and 3 exits
per theater. The food area has
9 exits. How many exits are
there altogether?
Answer:
51
Step-by-step explanation:
There are 14 movie theaters, and 3 exits each.
You can multiply 14 by 3 to get the number of exits in the movie theaters combined.
Next, the food area has 9, so you add 9 to the 42.
42 + 9 = 51.
Hope this helps!
Answer:
there are 51 exits

The required value of unknown number a would be 2000.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
WE need to determine 55% of what number is 1100.
Let the unknown number is a. then we get;
55% of a = 1100
55/100 of a = 1100
55/100 x a = 1100
Cross mulitiplication, we get;
55a = 1100 x 100
55a = 110000
Divide by 55, we have;
a = 110000/ 55
a = 10000/ 5
a = 2000
Therefore, the required value of unknown number a would be 2000.

Brandon buys a radio for $45.09 in a state where the sales tax is 7%. How much does he pay in taxes? If necessary round to the nearest cent
What is the total Brandon pays for the radio?
Answer:
Step-by-step explanation:
tax = 7% of $45.09 = 0.07×$45.09 ≅ $3.16
Total cost = $45.09 + $3.16 = $48.25

4x-3y = 12 and 3x+2y =6
Answer:
x = 42/17
y = -12/17
Step-by-step explanation:
4x - 3y = 12
3x + 2y = 6
use the elimination method (definition at the bottom of the page)
multiply both sides of the equation 4x - 3y = 12 by 2
8x - 6y = 24
multiply both sides of the equation 3x + 2y = 6 by 3
9x + 6y = 18
now, add the two equations:
17x = 42
x = 42/17
now, plug this into the equation 3x + 2y = 6
126/17 + 2y = 6
2y = -24/17
y = -12/17
We need a flower garden with a perimeter of 18 feet and an area of 18 square feet.what is the Length and width
Answer:
length is 6feet and width is 3 feet
Step-by-step explanation:
Area of the garden = LW
Perimeter of the garden = 2(L+W)
L is the length
W is the width
Given
Area = 18 square feet
Perimeter = 18feet
Substitute
18 = LW ... 1
18 = 2(L+W)
9 = L+W .... 2
From 2;
L = 9-W
Substitute into 1
18 = (9-W)W
18 = 9W-W²
W²-9W+18 = 0
W²-6W-3W+18 = 0
W(W-6)-3(W-6) = 0
W-3 = 0
W = 3 feet
Since L = 9-W
L = 9-3
L = 6feet
Hence the length is 6feet and width is 3 feet

Find x
To find x, we make use of:
[tex]cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]
In this case, it is:
[tex]cos(36) = \frac{x}{38}[/tex]
Multiply both sides by 38
[tex]38 * cos(36) = \frac{x}{38}*38[/tex]
[tex]38 * cos(36) = x[/tex]

XYZ has vertices X(3. -4), Y(6, 5), and Z(8, -2).find the coordinates of the vertices of X'Y'Z after a dilation of XYZ by a scale factor of 4
The coordinates of the vertices of X'Y'Z after a dilation of XYZ by a scale factor of 4 is X'(12, -16), Y'(24, 20) and Z'(32, -8).
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given that, XYZ has vertices X(3, -4), Y(6, 5), and Z(8, -2).
Scale factor = 4
Here, X(3, -4)→4(3, -4)→X'(12, -16)
Y(6, 5)→4(6, 5)→Y'(24, 20)
Z(8, -2)→4(8, -2)→Z'(32, -8)
Therefore, the coordinates of the vertices of X'Y'Z after a dilation of XYZ by a scale factor of 4 is X'(12, -16), Y'(24, 20) and Z'(32, -8).

Work out the percentage change to 2 decimal places when a price of £8.95 is increased to £10.
Answer:
The percentage change was of 11.73%.
Step-by-step explanation:
The percentage change of the increase is given by the change multiplied by 100 and divided by the initial value.
Price of £8.95 is increased to £10.
Change: 10 - 8.95 = 1.05
Initial price: 8.95
1.05*100/8.95 = 11.73%
The percentage change was of 11.73%.
A movie started at 2:30 PM. and ran for 1 Hour and 45 minutes.What time did the movie end?
Answer:
The movie ended at 4:15 PM
Step-by-step explanation:
=> It started at 2:30, when you add an hour to that it will become 3:30
=> Then you must add the 45 minutes to it
=> so it will be 3:75, however that is not a right answer and it is not logical
=> so you need to add the first 30 minutes which will give you 4:00
=> then add the rest which is 15 minutes
therefore, your answer is 4:15 PM

What is the slope of a line perpendicular to a line which has a slope of -2
Answer:
it is 1/2
Step-by-step explanation:
The product of a lines slope M and the slope K of a perpendicular is -1:
M*K=-1
This implies
K=-1/M
since
M * -1/M=-1
In our example we are given a line of slope M=-2 therefore the slope K of a line to perpendicular to this line is:
M*K=-1
-2*K=-1
K=-1/-2=1/2

Thirty-eight cities were researched to determine whether they had a professional sports team, a symphony, or a children's museum. of these cities, 21 had a professional sports team, 20 had a symphony, 17 had a children's museum, 14 had a professional sports team and a symphony, 10 had a professional sports team and a children's museum, 10 had a symphony and a children's museum, and 6 had all three activities. How many of the cities surveyed had only a professional sports team?
Answer:
3 of the cities surveyed had only a professional sports team.
Step-by-step explanation:
We solve this question treating these as Venn sets.
I am going to say that:
Set A: professional sports team.
Set B: Symphony.
Set C: Children's museum.
We start building from the intersection of these three.
6 had all three activities.
This means that [tex]A \cap B \cap C = 6[/tex]
10 had a symphony and a children's museum,
This means that:
[tex](B \cap C) + (A \cap B \cap C) = 10[/tex]
[tex](B \cap C) + 6 = 10[/tex]
[tex](B \cap C) = 4[/tex]
That is, 4 have only the symphony and children's museum, while 6 have all three.
10 had a professional sports team and a children's museum
[tex](A \cap C) + (A \cap B \cap C) = 10[/tex]
[tex](A \cap C) + 6 = 10[/tex]
[tex](A \cap C) = 4[/tex]
14 had a professional sports team and a symphony
[tex](A \cap B) + (A \cap B \cap C) = 14[/tex]
[tex](A \cap B) + 6 = 14[/tex]
[tex](A \cap B) = 8[/tex]
21 had a professional sports team
This means that:
[tex](A - B - C) + (A \cap B) + (A \cap C) + (A \cap B \cap C) = 21[/tex]
In which (A - B - C) represents the cities which had only a sports team. So
[tex](A - B - C) + 8 + 4 + 6 = 21[/tex]
[tex](A - B - C) = 3[/tex]
3 of the cities surveyed had only a professional sports team.
