Answer:
$8 each scarf
Explanation:
Let the selling price for each scarf be x,
Formula:
unit amount(selling price - cost price) = total profit
Stepwise:
100(x - 3) = 500
100(x) - 100(3) = 500
100x - 300 = 500
100x = 500 + 300
100x = 800
x = 8

What is perimeter and area of this object?
Answer:
Step-by-step explanation:
You have a circle with radius r = 3 ft and a 3-by-12 rectangle.
Area of circle = πr² = 9π ft²
Area of rectangle = 3 × 12 = 36 ft²
Total area = 36 + 9π ≈ 64.3 ft²
Perimeter of circle = 2πr = 6π ft
Perimeter of rectangular projections = 18 ft
Total perimeter = 6π +18 ≈ 36.8 ft
For each pair of mathematical expressions, determine if the expressions have equal values. Select each pair of expressions that came out to be equal.
Please note, not all pairs will come out to the same value. We want you to determine if the expressions in each answer option have the same value. A. 36 divided by 3+3 and 2^2 + 2. B. -(2/3)^2 and 4/9. C. 8(-9) and - 12 - 60. D. 1+2/4 and 1 - 1/4.
Answer:
A) equal
B) equal
C) equal
D) not equal
Step-by-step explanation:
The pairs of options (A), (B), and (C) of expressions came out to be 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 operations.
We want to determine if the expressions in each answer option have the same value
A. 36 divided by 3+3 and 2^2 + 2.
⇒ 36/(3+3) =36/6 =6
⇒ 2² + 2 = 4 + 2= 6.
Here, pair of expressions that came out to be equal
B. -(2/3)^2 and 4/9.
⇒ -(2/3)² = 4/9
Here, pair of expressions that came out to be equal
C. 8(-9) and - 12 - 60.
⇒ 8(-9) = -72
⇒ - 12 - 60 = -72
Here, pair of expressions that came out to be equal
D. 1+2/4 and 1 - 1/4.
⇒ 1+2/4 = 6/4
⇒ 1 - 1/4 = 3/4
Here, the pair of expressions came out to be not equal.
Thus, the pairs of options (A), (B), and (C) of expressions came out to be equal.

Write the slope intercept for of the equation
Answer: y = -3/2x + 5
Step-by-step explanation:
Answer:
y= 3/2x - 5
Step-by-step explanation:
Slope intercept form is y=mx + b
1. subtract 3x from both sides -2y= -3x + 10
2. divide -2 on each value y= 3/2x - 5
3. simplify if needed (already in simplest form)

how do I find the percent of budget?
Answer:
First, subtract the budgeted amount from the actual expense. If this expense was over budget, then the result will be positive.
Next, divide that number by the original budgeted amount and then multiply the result by 100 to get the percentage over budget. If your expenses were lower than your budgeted amount, then this number will be negative, describing the percentage under budget.

Find the perimeter of the semicircle below. Use 3.14 for
pi.
1.6 ft
Answer:
8.2ft
Step-by-step explanation:
Perimeter of a whole circle = 2*pi*r with radius r
Here we have 1.6ft as the radius so the whole circle's perimeter would be
2 * 3.14 * 1.6 = 10.048
We have half the circle so we half this number to 5.024.
Now we have to add the bottom straight line, which is two radii (two lots of 1.6)
5.024 + 1.6 + 1.6 = 8.224 which is rounded to 8.2ft
Pls help middle school math!!
Answer:
r = √A/π (radius = square root of a over pi)
Explanation:
There is a radius and a diameter. Diameter is the length of the whole circle across. The radius is half of the circle's length across, so half of the diameter.

Jenna's profit for selling 38 felt ornaments is $104.50. Suppose Jenna keeps track of the number of sales (x) and profit (y) on a graph. Which statements are correct?
Answer: B and E
Step-by-step explanation: Trust me, this is correct
The equation of the graph representing Jenna's profit is -
y = 2.75x
What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Jenna's profit for selling 38 ornaments is $104.50. Suppose Jenna keeps track of the number of sales (x) and profit (y) on a graph.
Assume that the equation of the graph representing Jenna's profit is -
y = mx + c
Then, it is a basic fact that with 0 sales, $0 profit will will be there. So, the line passes through (0, 0). Hence, the y - intercept [c] = 0. Then -
slope = [m] = (104.5)/38 = 2.75
So, the equation of line would be -
y = 2.75x
Therefore, the equation of the graph representing Jenna's profit is -
y = 2.75x

30 points!!!! a class of 30 students the Ratio of the numbers of boys to girls 7:8
How many girls are there in the class?
Answer:
16 girls in the class
14 boys in the class
Step-by-step explanation:
Because of the ratio of 7:8, I added 7+8.
7+8= 15
30 (the number of students in the class) divided by 15 (the sum of the ratio)
30/15= 2
I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.
Hope this helps!

There could be many answers: 2/12, 3/18, 4/24...
Step-by-step explanation:
You never really gave options but all you do is just take 1/6 and multiply the top and bottom by a certain number to get what you're looking for, for example 1/6 times 2, both on the top and bottom will get you 2/12 because 1 times 2 is 2 and, 6 time 2 is 12. :)
