Student Council sponsors weekly dances at their school on Friday nights. The admission price for each person is $4 for Student Council members. Members pay an annual fee of $50 for membership dues. How much will a member pay if they attend 15 dances during the school year.
Answer:
$110
Step-by-step explanation:
So first you have to do 15*4. We get the 4 from the admission fees and the 15 from the number of dances they attend. From this answer we can see the total of money they will be paying for admission for the 15 dances.
15*4=$60
However, our answer isn't just $50 as we are also told membership costs $50. So no we add $50 to $60, which gives us an answer of $110, which is the amount the member will pay if they attend 15 dances during the school year.
find x and y for this triangle
Answer:
x = 1.25
x = 1.75
Step-by-step explanation:
I marked the points of this triangle in the attached image so it's easier to explain.
ΔABC is similar to ΔADE, and all pairs of corresponding sides are proportional as a result.
[tex]\frac{DE}{BC}=\frac{AD}{AB}=\frac{AE}{AC}[/tex]
The length of the sides BC and DE is given, so I'll start with that and set it equal to the proportion between AB and AD.
[tex]\frac{DE}{BC}=\frac{AD}{AB}\\\\\frac{10}{8}=\frac{x+5}{5}\\\\10\times5=(x+5)\times8\\50=8x+40\\10=8x\\x=1.25[/tex]
Now, you can do the exact same thing for y:
[tex]\frac{DE}{BC}=\frac{AE}{AC}\\\\\frac{10}{8}=\frac{y+7}{7}\\\\10\times7=(y+7)\times8\\70=8y+56\\14=8y\\y=1.75[/tex]
Matthew has a gift card for $50 to lulu beans he is charged $3.25 for each coffee that he buys write an equation to represent his total amount left a after c coffees are purchased how many coffees were purchased if he has $11 left on the card
Answer:
Amt(c) = $50 - ($3.25/coffee)c
c = 12
Step-by-step explanation:
An equation to represent his total amount left a after c coffees are purchased
would be Amt(c) = $50 - ($3.25/coffee)c
and if he has $11 left, then $11 = $50 - ($3.25/coffee)c
or -$39 = -($3.25/coffee)c.
Dividing both sides by -$3.25, we get c = 12

Answer:
The expression is d(45) + 25 = c
Step-by-step explanation:
The expression is d(45) + 25 = c. Let's test it out to see if it is correct. We will test it out by substituting d and c.
Day 1:
For a day, the expression will be 1(45) + 25 = 70=> 45 + 25 = 70=> 70 = 70Day 2:
For two days, the expression will be 2(45) + 25 = 115=> 90 + 25 = 115=> 115 = 115Day 3:
For three days, the expression will be 3(45) + 25 = 160=> 135 + 25 = 160=> 160 = 160Day 4:
For four days, the expression will be 4(45) + 25 = 205=> 180 + 25 = 205=> 205 = 205Therefore, the expression is d(45) + 25 = c.

Maggie's brother is 7 years younger than four times her age. The sum of their ages is 68.
How old is Maggie?
=============================================
Explanation:
m = Maggie's age (some positive whole number)
4m = four times her age
4m-7 = seven years younger than 4m = brother's age
Add up her age (m) and her brother's age (4m-7) to get a sum of 68.
m+(4m-7) = 68
5m-7 = 68
5m = 68+7
5m = 75
m = 75/5
m = 15
Maggie is currently 15 years old.
Her brother is currently 4m-7 = 4*15-7 = 60-7 = 53 years old.
Their current year ages add to: 15+53 = 68 which confirms the answer.
A girl plays the same computer game lots of times.
The computer scores each game using 1 for the win, 0 for lose.
After each game, the computer calculates her overall mean score.
The graph shows the results for the first 20 games.
What percentage of the 20 games did the girl win?
Answer: 45%
From my common sense
If the graph line goes up, she wins.
If the graph line goes down, she loses.
1. Count the amounts of times which the graph line goes up.
(btw the first game she won because the graph line started at 1)
= 9
2. Calculate the winrate of her 20 games
= 9/20 * 100
= 45%

rectangle A and B are identical. each has a perimeter of 40cm. they are put together to make a new rectangle. the perimeter of the new rectangle is 68cm. work out the length and width of rectangle A.
Answer:
6 cm by 14 cm
Step-by-step explanation:
The perimeter of the joined figure will be the sum of the perimeters of rectangles A and B, less the lengths of the sides that are joined. The two joined sides have a total length of ...
(40 cm) +(40 cm) -(68 cm) = 12 cm
Then the length of the joined sides is 6 cm. The length of the other side of the rectangle is the difference between half the perimeter and this, or ...
(40 cm)/2 -6 cm = 14 cm
The length and width of rectangles A and B are 14 cm and 6 cm. When put together, they are joined on the 6 cm side.
