Jack and Jill have gone into business together, Jill promotes and sells
tickets for Jack who performs interpretive dance. They charge $2.50 for
adults and $1.25 for children. One performance sells 12 more tickets to
adult than children. In total they make $183.75. How many of each ticket
did they sell? *
Answers
Answer:
Number of children's ticket sold =41Number of adult ticket sold=53Step-by-step explanation:
Adult's ticket price= $2.50
Children's ticket price= $1.25
Let the number of children's ticket sold =xOne performance sells 12 more tickets to adult than children.
Therefore, the number of adult ticket sold =x+12In total they make $183.75.
Therefore, we have that:
1.25x+2.50(x+12)=$183.75
We solve the resulting equation for x.
Open the brackets
1.25x+2.5x+30=183.75
Collect like terms
3.75x=183.75-30
3.75x=153.75
Divide both sides by 3.75
x=41
Therefore:
Number of children's ticket sold ,x=41Number of adult ticket sold, x+12 =41+12=53Help me please show me how u got your answer PLZ and Thank You!!

Work out the surface area of the solid cuboid. The diagram is not drawn to scale.2cm,4cm and 5cm
Answers
The surface area of the solid cuboid is 76 cm²
Calculating the surface area of a cuboidFrom the question, we are to determine the surface area of the cuboid
The surface area of a cuboid is given by the formula,
Surface area = 2(lb + lh + bh)
Where l is the length
b is the breadth
and h is the height
Let
l = 5 cm
b = 4 cm
h = 2cm
Then,
Surface area = 2(5×4 + 5×2 + 4×2)
Surface area = 2(20 + 10 + 8)
Surface area = 2(38)
Surface area = 76 cm²
Hence, the surface area of the solid cuboid is 76 cm²

6. Suppose you bought supplies for a party. Three rolls of streamers and 15 balloons
cost $30. Later, you bought 2 rolls of streamers and 4 balloons for $11. How much did
each roll of streamers cost? How much did each balloon cost?
Answers
Answer:
Streamers are $2.50 each
Balloons are $1.50 each
Step-by-step explanation:
Make a system of equations
3s + 15b = 30
2s + 4b = 11
Solve by elimination: multiply the top equation by 2 and the bottom equation by -3.
6s + 30b = 60
-6s -12b = -33
18b = 27
b = 1.5
Plug in 1.5 as b to find s
3s + 15(1.5) = 30
3s +22.5 = 30
3s = 7.5
s = 2.5
The streamers are $2.50 and the balloons are $1.50

AD←→ is tangent to circle M at point D. The measure of ∠DMQ is 58º.
What is the measure of ∠DQM ?
Answers
Answer:
32°
Step-by-step explanation:
Given:
∠DMQ = 58º
In this circle, the radius is DM. Since AD is tangent to the circle M, at point D, and the angle between a tangent and a radius is 90°
Therefore, ∠MDQ = 90°
The total angle in a triangle is 180°. Since we have the values of ∠MDQ and ∠DMQ, ∠DQM will be calculated as:
180 = ∠DMQ + ∠MDQ + ∠DQM
Solving for ∠DQM, we have:
∠DQM = 180 - ∠DMQ - ∠MDQ
∠DQM = 180 - 90 - 58
∠DQM = 32°
The measure of ∠DQM is 32°

Answers
Answer: μ = 647.4
Step-by-step explanation:
The question says
"A psychologist has designed a questionnaire to measure individuals' aggressiveness. suppose that the scores on the questionnaire are normally distributed with a standard deviation of . suppose also that exactly of the scores exceed"
And we are told to find the mean of the distribution scores.
Given mean μ = ?
we have from standard normal table that
P(Z > 1.282) = 0.1
Therefore the given Z score of a score of 750 is given thus 1.282.
the z score is given:
x - μ / α = 1.282
750 - μ / 80 = 1.282
Therefore μ = (750 - 80)*1.282 = 647.4
So we have that μ = 647.4

Complete question:
While making oatmeal cookies, Angela needs to add 1/2 cup of milk to her dough. However, she has only a 1/4-cup measuring cup. How many times does she need to fill the measuring cup to pour 1/2 cup of milk? The number of times Angela needs to fill the 1/4-cup measuring cup to pour 1/2 cup of milk is?
Step-by-step explanation:
Number of cups Angela needs to add to her dough = 1/2 cup of milk
The only measuring cup she has = 1/4-cup measuring cup.
To determine the number of times she needs to fill the measuring cup to pour 1/2 cup of milk, we would divide the 1/2 cup of milk by 1/4-cup measuring cup
= ½ ÷ ¼
= ½ × 4/1
= 4/2
= 2
Angela would need to fill 2 times
Therefore, the number of times Angela needs to fill the 1/4-cup measuring cup to pour 1/2 cup of milk is 2

Answer:
type 2 in the first box,
13/4 in the second box, and
-9/8 in the third one
Step-by-step explanation:Notice that you are asked to write the following quadratic expression in vertex form, so you need to find the "x" value of the vertex, and then the "y" value of the vertex:
[tex]x_{vertex}= -b/2a[/tex]
Which in our case is: -13/4
and the value of the y for the vertex is obtained using the functional expression when x equals -13/4:
[tex]f(-13/4)= -9/8[/tex]
Then your expression for this quadratic should be:
[tex]f(x)=2\,(x+\frac{13}{4} )^2+(-\frac{9}{8})[/tex]
Then type 2 in the first box, 13/4 in the second box, and -9/8 in the third one
Given that ∠ABC ≅ ∠DBE, which statement must be true?
∠ABC ≅ ∠ABD
∠ABD ≅ ∠CBE
∠CBD ≅ ∠DBE
∠CBD ≅ ∠ABC
Answers
Answer:
∠ABD ≅ ∠CBE
Step-by-step explanation:
So we know that ∠ABC ≅ ∠DBE. Those angles equal the same thing. Let's represent that with x.
So does ABD = CBE?
Well we can model that with our xs.
ABD = ABC + CBD
so ABD = x + CBD
CBE = DBE + CBD
so CBE = x + CBD
Look at what we have!
x + CBD = x + CBD.
You can tell that ∠ABD ≅ ∠CBE because those given angles are equal to each other.
Or for an easier (but lazier) method, you can just look at the diagram, which is actually drawn to a reasonable scale. You can tell right off the bat that none of the other options work.
