A. 12 boys and 9 girls
B. 12 boys and 16 girls
C. 9 boys and 16 girls
D. 12 boys and 15 girls
Answer:
B 12 boys and 16 girls
Step-by-step explanation:
Make the ratios into fraction form. Simplify all of the fractions. The fraction that equals the original ratio is the correct answer. Dived both 12 and 16 by 4 and you get 3 and 4.
Brainliest please
Answer:
B
Step-by-step explanation:
Because 3 times 4 is 12 and 4 times 4 is 16 so that shows that they are equivalent hope it helps have a nice day
James called his pen pal in England on World Hello day .The cost of the call was $7.75 . The charge for the first minute was $ 1. Each extra minute cost $ 0.25 . Write an equation and solve it to find out how long James call lasted.
Given:
Total cost of the call = $7.75
The charge for the first minute was $ 1. Each extra minute cost $ 0.25.
To find:
The equation for this situation and the call duration.
Solution:
Let x be the call duration in minutes.
Remaining minutes after first one minute = x-1
Cost of first minute = $1
Cost of 1 extra minute = $0.25
Cost of (x-1) extra minutes = $0.25(x-1)
Total cost of call = Cost of first minute + Cost of extra minutes
[tex]7.75=1+0.25(x-1)[/tex]
[tex]7.75=1+0.25x-0.25[/tex]
[tex]7.75=0.25x+0.75[/tex]
[tex]7.75-0.75=0.25x[/tex]
[tex]7=0.25x[/tex]
Divide both sides by 0.25.
[tex]\dfrac{7}{0.25}=x[/tex]
[tex]28=x[/tex]
Therefore, the required equation is [tex]7.75=1+0.25(x-1)[/tex] and call duration is 28 minutes.

HELP! 25 points! I'm really bad at math and need to find out the angle of x
angle CEB and AED are corresponding angles, so they are both are equal
since we already know that CEB is equal to 160, that means that AED is also equal to 160
all you have to do to find the value of x is subtract the 115 from 160, and so you get 45
so, x=45

Answer:

Step-by-step explanation:
Enter the ordered pair for the vertices for T(3, –2)(QRST).
Given:
The figure QRST.
The rule of translation is [tex]T_{(3,-2)}(QRST)[/tex].
To find:
The coordinate of vertices after translation.
Solution:
According to the given rule of translation is [tex]T_{(3,-2)}(QRST)[/tex], we get
[tex](x,y)\to (x+3,y-2)[/tex]
From the given figure it is clear that the vertices of QRST are Q(1,3), R(3,-3), S(0,-2) and T(-2,1).
Using the above rule, we get
[tex]Q(1,3)\to Q'(1+3,3-2)=Q'(4,1)[/tex]
[tex]R(3,-3)\to R'(3+3,-3-2)=R'(6,-5)[/tex]
[tex]S(0,-2)\to S'(0+3,-2-2)=S'(3,-4)[/tex]
[tex]T(-2,1)\to T'(-2+3,1-2)=T'(1,-1)[/tex]
Therefore, the coordinates of the vertices after translation are Q'(4,1), R'(6,-5), S'(3,-4) and T'(1,-1).
The ordered pairs for the vertices of T(3, –2)(QRST) are
[tex]\mathbf{Q' = (4,1)}[/tex] [tex]\mathbf{R' = (6,-5)}[/tex] [tex]\mathbf{S' = (3,-4)}[/tex] and [tex]\mathbf{T' = (1, -1)}[/tex]
The coordinates of QRST are:
[tex]\mathbf{Q = (1,3)}[/tex]
[tex]\mathbf{R = (3,-3)}[/tex]
[tex]\mathbf{S = (0,-2)}[/tex]
[tex]\mathbf{T = (-2,1)}[/tex]
The transformation rule of [tex]\mathbf{T(3,-2)}[/tex] is:
[tex]\mathbf{(x,y) \to (x + 3,y -2)}[/tex]
So, we have:
[tex]\mathbf{Q' = (1 + 3,3 -2)}[/tex]
[tex]\mathbf{Q' = (4,1)}[/tex]
[tex]\mathbf{R' = (3 + 3,-3 -2)}[/tex]
[tex]\mathbf{R' = (6,-5)}[/tex]
[tex]\mathbf{S' = (0 + 3,-2 -2)}[/tex]
[tex]\mathbf{S' = (3,-4)}[/tex]
[tex]\mathbf{T' = (-2 + 3,1 -2)}[/tex]
[tex]\mathbf{T' = (1, -1)}[/tex]
Hence, the ordered pairs for the vertices of T(3, –2)(QRST) are
[tex]\mathbf{Q' = (4,1)}[/tex] [tex]\mathbf{R' = (6,-5)}[/tex] [tex]\mathbf{S' = (3,-4)}[/tex] and [tex]\mathbf{T' = (1, -1)}[/tex]

Step-by-step explanation:
The track team plans to buy new jerseys. If they buy more than 25 jerseys, the cost is $12.99 each. The total cost of the jerseys is a function of the number purchased, n. C(n) = 12.99n Use the drop-down menus to complete the statements below about the domain of this function.
Answer:
The answer is below
Step-by-step explanation:
A function shows the relationship between two variables (that is an independent variable and a dependent variable).
The domain of a function is the set of all input variables (that is independent variables).
Given the function C(n) = 12.99n, C(n) is the dependent variable representing the cost and n is the dependent variable which is the number of jerseys.
Since the customer has to buy more than 25 jerseys, the domain is:
Domain = 25 < n ≤ ∝

Answer:
y = 4x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 4 and c = 3, then

Alec says the sum of two numbers can never be less than either number.
Use a model to explain why Alec is incorrect,
Answer:
If you put two things together it cannot be less than what was originally there.
Step-by-step explanation:
For example if you have two bowls of soup and you add them together you will have more soup.
Alec is incorrect because this inequality of model 1 + 2 < 4 i.e. the sum of two numbers is greater than either number.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Alec says the sum of two numbers can never be less than an either number.
Using a model a + b < c
Substitute the values a = 1, b = 2, and c = 4 in the inequality of model
1 + 2 < 4
So, the sum of two numbers is greater than either number.
Hence, Alec is incorrect.

a can holds 2 liters of paint.
then how many can we fill with 11 liters of paint
Answer:
5 and a half
Step-by-step explanation:
Because you can fit 2 liters in each can, to find how many you would need, divide 11 by 2, this would give you 5 and a half, 5.5.
It could be that they want you to round up to six or round down to five, so do consider that.

16.) C b/c if you draw a line through it you have line of symmetry and a regular hexagon has rotational symmetry.
PAGE 2
11.) P(6, 2) ----(6*3, 2*3) -----> P'(18, 6)
So e is the answer
12.) The compound transformation should read
Dilation with center at origin and scale factor of 1/2
Reflection across the x-axis
Reflection across the x-axis rule is (x, y) -->(x, -y)
a is the answer b/c A(-1, -2) --> A'(-1/2, -1) --> (-1/2, 1)
PAGE 3
13.) The scale of the dilation is 1/4 b/c ---> 25*1/4 = 6.25 and 64*1/4 = 16
So 16*1/4 = 4 and 10*1/4 = 2.5, so e is the answer
14.) Dilation b/c you can either enlarge or reduce the pre-image.
15.) A heptagon has 7 lines of symmetry b/c it is equal to the number of sides

A band earned $550.00 for playing at a concert. Their manager takes 15% of the money earned for each show and the band is donating 20% of the money earned to charity. How much money is left for the band to split?
Answer:
The amount of the money earned left for the band to split is $357.5
Step-by-step explanation:
The amount the band earned for playing at the concert = $550.00
The percentage of the money earned taken by the manager = 15%
The percentage of the money earned the band is donating to charity = 20%
The amount of the money earned the manager takes = 15/100 × 550 = 82.5
∴ The amount of the money earned the manager takes = $82.5
The amount of the money earned that is donated to charity = 20/100 × 550 = 110
∴ The amount of the money earned that is donated to charity = $110
The amount of the money earned left for the band to split = $550 - $82.5 - $110 = $357.5.
