Using proportions, it is found that:
The markup amount is of $400.The price of each bracelet is of $14.What is a proportion?A proportion is a fraction of a total amount.
In this problem, the markup is of 40% over an amount of $1000, hence:
0.4 x $1000 = $400.
Considering the markup, 100 bracelets will be sold for $1,400, hence, the price of each bracelet will be given by:
$1,400/100 = $14.

You want to take 12 shirts, but you can only fit 3 in your suitcase. How many different ways can you choose shirts to pack?
Answer:
220 ways.
Step-by-step explanation:
This can be gotten by using the formula of combination in statistics.
The formula for combination is given below
nCr = n! / r!(n - r)!, where
r = total number of object, and
n = number of objects we're choosing from
Applying this to the question we have
12C3 = 12! / 3!( 12 - 3)!
12C3 = 12! / 3! * 9!
12C3 = 220
Therefore, we can choose to pack the shirts in 220 different ways

The zeros of a quadratic function are -7 and 3. Which of the following could be the function? Select all that apply.
A. F(x)=2x^2-8x-42
B. F(x)=5x^2+20x-105
C. F(x)=x^2+4x-21
D. F(x)=x^2-4x-21
The possible functions are
A. F(x)=2x^2-8x-42
B. F(x)=5x^2+20x-105
C. F(x)=x^2+4x-21
How to determine the possible equations?The zeros are given as:
x = -7 and x = 3
Rewrite as:
x +7 = 0 and x - 3 = 0
Multiply both zeros
(x + 7) * (x - 3) = 0 * 0
Evaluate the product
x^2 + 7x - 3x - 21 = 0
Evaluate the like terms
x^2 + 4x - 21 = 0
Express as a function
f(x) = a(x^2 + 4x - 21)
Where a is a constant
Let a = 1, 2 and 5 (according to the values in the options)
f(x) = 1 * (x^2 + 4x - 21) = x^2 + 4x - 21 --- option (c)
f(x) = 2 * (x^2 + 4x - 21) = 2x^2 + 8x - 42 --- option (a)
f(x) = 5 * (x^2 + 4x - 21) = 5x^2 + 20x - 105 --- option (b)
Hence, the possible functions are (a), (b) and (c)

An envelope has a perimeter of 30 inches. Its area is 50 square inches. What are the dimensions of the
envelope?
inches by
inches
Answer:
10in by 5in
Step-by-step explanation:
PERIMETER: p=2(a+b) p=30
AREA: A=a×b A=50
2(a+b)=30
a×b=50
Answer:
The dimensions of the envelope are 5 by 10 inches.
Step-by-step explanation:
Perimeter formula for a rectangle: P = 2W + 2L
Area formula ' " " A = W*L
Here, P = 2W + 2L, so 30 in = 2W + 2L, or 15 in = W + L
Also, A = W*L, so 50 in^2 = W*L, or (if we solve this for W) W = (50 in)/L
But 15 = W + L, or 15 - L = W. Substitute this result for W in the equation W = (50 in)/L:
We get (50 in)/L = 15 - L
Multiplying both sides by L eliminates the fraction:
50 in = 15L - L^2, or
L^2 - 15L + 50 = 0
This factors into (L - 10)(L - 5) = 0, so L is either 10 or 5. Because 15 - L = W, W is either 10 or 5.
The dimensions of the envelope are 5 by 10 inches.

Ferdinand is playing golf. He hits a shot off the tee box that
has a height modeled by the function h(t) = –16t2 + 80t,
where h(t) is the height of the ball, in feet, and t is the time
in seconds it has been in the air. The graph that models
the golf ball's height over time is shown below.
When does the ball reach its maximum height?
What is the maximum height of the ball?
Answer:
Maximum height of the ball = 100 m
Time to reach the maximum height = 2.5 seconds
Step-by-step explanation:
Function that models the height h(t) of the ball and time 't',
h(t) = -16t² + 80t
Convert this equation into vertex form,
h(t) = -16(t²- 5t)
= -16[t² - 2(2.5t) + (2.5)² - (2.5)²]
= -16[[t² - 2(2.5t) + (2.5)²] + 16(2.5)²
= -16(t - 2.5)² + 16(6.25)
= -16(t - 2.5)² + 100
By comparing this equation with,
g(t) = a(x - h)² + k
Here, (h, k) is the vertex of the parabola.
Vertex of the given parabola will be → (2.5, 100)
Therefore, maximum height of the ball = 100 m
Time taken by the ball to reach the maximum height = 2.5 seconds

2x + 3y + 5
2z + y
x + 3y
Given is that there are 6 children on a bus. Each child is wearing a hat.
Total number of children in the bus = 6
Number of children wearing a hat = 6
Fraction of children wearing a hat -
n = (Number of children wearing a hat/Total number of children in the bus)
n = 6/6
n = 1
Therefore, all 6 childrens in the bus are wearing a hat.

Lisa, Kelly, and Maria have $56.70. If Lisa has $23.20 and Kelly has $15.05, which equation shows how much money, n, Maria has
Answer:
38.25+n=56.70
Step-by-step explanation:
23.20+15.05+n=56.70
38.25+n=56.70
Answer:
Maria has $18.45.
Explanation:
All three of them have $56.70 all together.
So you would want to add Lisa's amount with Kelly's amount to get how much they have together.
23.20 + 15.05 = 38.25
Then you take the amount of money Lisa and Kelly has together and subtract it from the total amount of money all three of them have together to get Maria's amount.
56.70 - 38.25 = 18.45
Maria has $18.45.
Check:
Add all three of there money amounts together and if you get $56.70 you got the right answer.
23.20 + 15.05 + 18.45 = 56.70
You have 6 people working to set up for tonight's banquet, and each person can set up 13 tables per hour. You need to have 500 tables set up by 6pm. When should they begin setup?
You should begin setup by 12 PM to setup 500 tables.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, you have 6 people working to set up for tonight's banquet, and each person can set up 13 tables per hour.
So, in one hour total number of table can set up = 6×13
= 78
Number of hours = 500/78
= 6.41
≈ 6 hours
Therefore, you should begin setup by 12 PM to setup 500 tables.
