Answer:
50 yards.
Step-by-step explanation:
Since we know that 5 yards can make 2 costumes, we can divide 5/2 to find 2.5 yards are needed to make one costume. Then you can multiply 2.5*20 to get 50 yards needed for 20 costumes. Hope this helps :)
Tulip bulbs are on sale at store A, at 5 for $11.00, and the regular price at store B is 6 for $13. Is each store pricing tulip bulbs at the same rate? Explain how you know.
Answer:
No, they are not sold at the same rate
Step-by-step explanation:
An easy way to figure situations like these can be taking the number of items there and then dividing by the total price. For A, each bulb costs $2.2, for B each bulb costs $2.1666.
11/5=2.2
13/6=2.1666
are the expression -7 + -2 and -7 - 2 equivalent why or why not? include the solutions for each expression for full credit
Answer:
Yes, they are both equal.
Step-by-step explanation:
This is because in both cases, you are subtracting, -7 + -2 = -9. -7 - 2 = -9.

1) Point P has the coordinates (5,7) what is the image of P' after a 90-degree Rotation? 2) Point P has the coordinates (5,7) what is the image of P' after a 180-degree Rotation? 3) Point P has the coordinates (5,7) what is the image of P' after a 270-degree Rotation? 4) Point A has the coordinates (-5,7) what is the image of A' after a 90-degree Rotation? 5) Point Q has the coordinates (5,7) what is the image of Q' after a 270-degree Rotation? 6) L' (6,-7) is the image of L after a 180 rotation what are the original coordinates L 7) The point A (-5,-8) is first translated 6 units to the right and two units down to get A'.A' is then reflected in the y=-x line to get A''.A'' is then rotated counterclockwise around the origin 270 degrees to get A'''.What are the coordinates of A'''?
Answer:
1) The coordinates of P' is (7, -5)
2) The coordinates of P' is (-5, -7)
3) The coordinates of P' is (-7, 5)
4) The coordinates of A' is (7, 5);
5) Q' is (-7, 5)
6) The coordinates of L is (-6, 7)
7) The coordinates of A''' is (1, 10)
Step-by-step explanation:
1) The coordinates of a preimage (x, y) after 90-degrees clockwise rotation gives the image (y, -x)
Therefore, given that the preimage P is (5, 7), we have the image, P', after 90 degrees clockwise rotation is (7, -5);
2) The coordinates of a preimage (x, y) after 180-degrees clockwise rotation gives the image (-x, -y)
Given that the preimage, point P, has coordinates (5, 7) the image, P', after 180-degrees rotation becomes (-5, -7)
3) The coordinates of a preimage (x, y) after 270-degrees clockwise rotation gives the image (-y, x)
∴ The coordinates of the preimage, P = (5, 7), after 270-degrees clockwise rotation gives the image, P', = (-7, 5)
4) The coordinates of a preimage (x, y) after 90-degrees clockwise rotation gives the image (y, -x)
Therefore, given that the preimage A is (-5, 7), we have the image, A', after 90 degrees clockwise rotation is (7, 5);
5) The coordinate of the preimage, point Q is (5, 7) after 270-degrees clockwise rotation gives the image, Q', = (-7, 5)
6) The image of a preimage, (x, y) after 180-degrees rotation is (-x, -y). Therefore, given that the image of the preimage L, after 180 degrees rotation is L' (6, -7), we have the coordinates of L is (-6, 7)
7) The coordinates of the preimage, A = (-5, -8)
a) A is translated 6 units to the right and 2 units to give;
A'(-5 + 6, -8 - 2) = A'*1, -10)
b) (x, y) is reflected across the line y = -x, to give (-y, -x)
∴ A'(1, -10) is reflected across the line y = -x, A''(10, -1)
c) The coordinates of a preimage (x, y) after 270-degrees clockwise rotation gives the image (-y, x)
∴ The coordinates of the preimage, A''(10, -1), after 270-degrees clockwise rotation gives the image, A'''(1, 10).
2. Below are the graphs of y = |x| and y = |x| + 11. How are the graphs related?
10
10-8
10
a. The two graphs are the same.
b. The graphs have the same y-intercept. The second graph is steeper than y = |xl.
C. The graphs have the same shape. The y-intercept of y = x is 0 and the x-intercept of the
second graph is 11.
d. The graphs have the same shape. The y-intercept of y = x is 0 and the y-intercept of the
second graph is 11.
How do you solve 2(x-6)=x-14
Answer:
x = -2
Step-by-step explanation:
[2(x-6) = x - 14]
Multiply 2 by x and (-6) in parenthesis, distribution
[2x -12 = x - 14]
Add 12 to both sides
[2x = x - 2]
Subtract x from both sides
[x = -2]

In school ,there are 3 girls for every 2 boys . There are 650 students in total . How many students are girls ?
Answer:
Girls = 390
Step-by-step explanation:
Set up a proportion:
In a sample of 3:2, you have 5 kids in all.
So the the ratio of girls to kids in a sample of 5 is 2:5.
So set up a proportion:
(3/5) = (x/650)
5x = 650(3)
5x = 1950
x = 390
Answer:
390Step-by-step explanation:
Let number of boys be b and girls be g. Then we have:
g/b = 3/2g + b = 650From the first equation b is:
b = 2g/3Substitute b in the second equation
g + 2g/3 = 6505g/3 = 650g = 650*3/5g = 390If the venue needs to sell 86 tickets to break even, then how much money have they invested in the concert
Answer: the first one is 2924
If there’s a next question after that about the venue’s capacity the answer is 6800
Hope this helps! ^^
1. A movie theater sells tickets for $9.00 each. Senior citizens receive a discount of $3.00. One evening the theater
sold 636 tickets and took in $4974 in revenue. How many tickets were sold to senior citizens?
Answer:
250
Step-by-step explanation:
x is adult tix, y is senior tix
9x + 6y = $4974
x+y= 636
x=636-y
9(636-y) +6y = 4974
5724 - 9y + 6y = 4974
-3y = 4974-5724
-3y=-750
y=250
What is an equation of the line that passes through the point (5, 4) and is parallel to
the line 6x – 5y = 15?
Answer:
6x - 5y does not change as it is parallel so I put x = 5 & y = 4 in this equation and the result is 6 × 5 - 5 × 4 = 30 - 20 = 10 so the parallel equation is 6x - 5y = 10

364x476= 173264
173264⁻¹⁰⁰= 0
0+30 = 30
an exponential function is graphed on the grid
based on the graph, which statement about the function is true
a) the domain is the set of all real numbers
b) the domain is the set of all real numbers less than 3
c) the range is the set of all real numbers greater than or equal to 0
d) the range is the set of all real numbers greater than or equal to -9
Answer:
a) the domain is the set of all real numbers
Step-by-step explanation:
Given:
An exponential function and its graph.
A line parallel to [tex]x[/tex] axis is drawn at [tex]y=-9[/tex] which is a dashed line.
Dashed line means, the function does not attain a value equal to [tex]y=-9[/tex].
Domain of a function, [tex]y=f(x)[/tex] is the set of values which can be possible for the variable [tex]x[/tex] that can be given as input.
Range of a function, [tex]y=f(x)[/tex] is the set of possible values of [tex]y[/tex] i.e. the output of the function.
As seen from the graph, the domain of the exponential function does not have any constraint on it.
Therefore, any real number can be given as input.
So, a) The domain is the set of all real numbers.
Let us discuss about the range of function.
As stated above as well, the range of the function can not contain the value [tex]y=-9[/tex].
And there is no value possible below it.
So, the range is all real numbers greater than -9.
The answer is:
"a) the domain is the set of all real numbers" is true.
