Step-by-step explanation:
Chloe charged for admission to her play on three different nights. Each night, a
different number of people were in attendance, but remarkably, Chloe collected
S541 each night. If the admission charges for each child and each adult were $9
and S17, respectively, how many people in total came to the three showings?
Answer:
The number of people in total that came to the three showings is 138 people
Step-by-step explanation:
The amount Chloe collected each night for admission to her play = $541
The admission charge for each child = $9
The admission charge for each adult = $17
The number of people attending the play each of the three nights are different
Let x represent the number of children that attend the play on the first night and ley y represent the number of adults that attend, we have;
9·x + 17·y = 541
For the second night, we have;
9·a + 17·b = 541
For the third night, we have;
9·c + 17·d = 541
27·(x + a + c) + 51·(y + b + d) = 1,623
Using Microsoft Excel, where we create a series with the first term = 541 and the common difference, d = -9 and number the adjacent column serially from 1 to 61 and the on the right column we divide the created series by 17 then we search for the whole number combinations, we get three possible combinations as follows;
12 children and 26 adults
29 children and 17 adults
46 children and 8 adults
Therefore, the number of people in total that came to the three showings = 12 + 26 + 29 + 17 + 46 + 8 = 138
The number of people in total that came to the three showings = 138 people.

Complete question is;
Mika taught her sister the steps for dividing a decimal by a decimal. Which instructions are correct?
A) 1. Multiply the divisor by a multiple of 10 to create an integer divisor. 2. Multiply the dividend by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
B) 1. Multiply the dividend by a multiple of 10 to create an integer. 2. Multiply the divisor by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
C) 1. Divide the divisor by a multiple of 10 to create an integer divisor. 2. Divide the dividend by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
D) 1. Divide the dividend by a multiple of 10 to create an integer. 2. Divide the divisor by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
Answer:
A) 1. Multiply the divisor by a multiple of 10 to create an integer divisor. 2. Multiply the dividend by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
Step-by-step explanation:
In Mathematics, divisor is the number by which the dividend should be divided.
Now, if we want to divide a decimal by another decimal, to make things easy we have to transform both numbers from decimals to integer form to make direct division easier.
The first step will be to multiply the divisor by a multiple of 10. The multiple of 10 will depend on the number of decimal places.
The second step is to do the same to the dividend.
The last step would be to divide the integers by applying rules of division of numbers.
The correct option is Option A:
Dilate by a scale
factor of 1/2
AL
D
Answer:
The image triangle ΔD'L'W' after the dilation by a scale factor of 1/2 will have the vertices:
D' (0, 1) L' (1/2, 5/2) or L'(0.5, 2.5)W' (5/2, 2) or W'(2.5, 2)`The figure of the dilated image is attached below.
Step-by-step explanation:
Given the triangle ΔDLW withe the vertices
D(0, 2)L(1, 5)W(5, 4)As the scale factor 1/2 < 0, thus the image triangle will be smaller than the original triangle.
The rule of dilation is given by
Dilation: (x, y) → (1/2x, 1/2y), centered at (0, 0)
D(0, 2) → D' (1/2x, 1/2y) → D' (1/2(0), 1/2(2)) = D' (0, 1)
L(1, 5) → L'(1/2x, 1/2y) → L'(1/2(1), 1/2(5)) = L' (1/2, 5/2)
W(5, 4) → W'(1/2x, 1/2y) → W'(1/2(5), 1/2(4)) = W' (5/2, 2)
Therefore, the image triangle ΔD'L'W' after the dilation by a scale factor of 1/2 will have the vertices:
D' (0, 1) L' (1/2, 5/2) or L'(0.5, 2.5)W' (5/2, 2) or W'(2.5, 2)`The figure of the dilated image is attached below.
The value of (3a – 4b + 2) × (5a + 6) for a = 1 and b = -2 is
Step-by-step explanation:
We know that
a=1 and b= -2
{3*1-4*(-2)+2} .{5*1+6}
= (13-11)
=2
Answer:
143
Step-by-step explanation:
(3a – 4b + 2) × (5a + 6)
a = 1 ; b = - 2
(3(1) – 4(-2) + 2) × (5(1) + 6)
Inputting the values of a and b
(3 - (-8) + 2) * (5 + 6)
(3 + 8 + 2) * (11)
13 * 11
= 143

what is x if: 5÷x=30
Answer:
x = 1/6
Step-by-step explanation:
Rewrite the equation to get 5/x = 30. Multiply x on both sides to get 5 = 30x. Then divide 30 on both sides to get your x value which is 1/6.
Answer:
x= 1/6
Step-by-step explanation:
multiply both sides by x
divide both sides by 30
simplify 5/30 to 1/6
Find the surface area of this triangular prism.
Please explain as well, I’m struggling with it.
Answer:
SA= 84 cm^2
Step-by-step explanation:
So first locate all the surfaces
we got 5 sides in total
Now calculate each one
Lets start with the 2 triangles
so formula for area of triangl is 1/2(b*h)
So in this case it’s 6
Now there are 2 identical triangles
So Times the 6 by 2
You’ll get 12
Thats 2 sides
Now for the side with the rectangle of 5cm and 6cm
Area of rectangle is 5*6=30
That would onay be 1 side
Now for the bottom of the prisim which is the side with 4cm and 6cm
Same rectangle so multiply
4*6=24
Thats another side down
The last side is on the left with the back not visible. The two dimensions are 6 and 3
Now multiply 6*3
18
Now add up your total
18+24+12+30=84
So 84 cm^2 OR 84 square centimeters
Answer:
84 [tex]cm^{2}[/tex]
Step-by-step explanation:
To find the surface area of a prism, one will have to find the area of each of the sides of the prism, then add the areas up. First, find the dimensions of each of the sides
Front; 5 x 6
Front triangle; 3 x 4
Back triangle; 3 x 4
Bottom; 4 x 6
Back; 3 x 6
The front is a rectangle, hence one has to [tex]base * height[/tex] to find the area;
5 x 6
= 30
The front triangle is a triangle, hence on has to do [tex]\frac{base * height}{2}[/tex] to find the area;
[tex]\frac{3*4}{2}[/tex]
= 6
The back triangle is a triangle, hence on has to do [tex]\frac{base * height}{2}[/tex] to find the area;
[tex]\frac{3*4}{2}[/tex]
= 6
The back is a rectangle, so one has to do [tex]base * height[/tex] to find the area;
4 * 6
= 24
The bottom is a rectangle, o one has to do [tex]base * height[/tex] to find the area;
3 * 6
= 18
Noe one has to add up all the areas to find the total surface area;
Front + Front_triangle + Back_triangle + Bottom + Back
30 + 6 + 6 + 24 + 18
= 84

please help me on this!
Answer:
(a.) B: 8,000
(b.) C: 800
(c.) A. 10 times
Step-by-step explanation:
8762 has 3 digits after the 8. 8,000 has 3 digits after the 8
851 has 2 digits after the 8. 800 has 2 digits after the 8.
8,000 ÷ 800 = 10
Another way to do it is: 8000 has 3 zeros and 800 has 2 zeros.
3 - 2 = 1. 10 has 1 zero.

What is a slope of a line parallel to the line whose equation is Y - X = 5
A) -1
B) 1/5
C) 1
D) 5
Answer:
C
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 )
Given
y - x = 5 ( add x to both sides )
y = x + 5 ← in slope- intercept form
with slope m = 1
Parallel lines have equal slope, thus
the slope of a parallel line is m = 1 → C

How can you write an equation to solve a problem?
(written response)
( 20 points)
Answer:
if you have a specific math problem i can help you with it!
Step-by-step explanation:
you essentially translate the words into math. for example if the problem says something like "he has 5 more pieces of candy than her" you would set a variable, in this case "x," and set it up like this.
since "her" is the original amount, we'd do it like this:
her = x
he = x+5
then, we'd figure out what these values have to equal to. let's say there are 9 total pieces of candy. so this is how we'd do it:
(x)+(x+5)=9
now we solve:
2x+5=9
2x=9-5
2x=4
x=2
hope this somewhat helped! if you have more questions, feel free to ask me!
