A vendor pays a rock band 1/3 of the total profit from T-shirts and sweatshirts sold at every concert. The vendor paid the rock band $726 after the last concert. If the profit from T-shirts sales was $1,632, what was the profit from sweatshirt sales?
Answers
Using this information, we know that is we multiply 1/3 by 3 we get 1 whole, so we also multiply $726 by 3 to get the value of all the profits:
$726×3= $2178
So, if $2178 was the total value of the profits and T-shirt profits were worth $1632, then the value of sweatshirt profits was $2178-$1632= $546
Therefore, your answer is $546

The amount of money that Charlie saves each week is directly proportional to the amount he earns. Last week Charlie saved $32 on his earnings of $512. At the same rate, how much will Charlie save this week on his earnings of $448?
Answers
512= k ·32 so k=512/32=16;
This week
448= k · amount he saved
448=16· amount he saved
amount saved=448/16=28
Answer $28
Answer:
$28.
Step-by-step explanation:
Let y represent of saved money and x represent amount of earned money.
We have been given that the amount of money that Charlie saves each week is directly proportional to the amount he earns.
We know that two proportional quantities are in form [tex]y=kx[/tex], where, k is constant of proportionality.
Substitute given values and solve for k:
[tex]32=k*512[/tex]
[tex]\frac{32}{512}=\frac{k*512}{512}[/tex]
[tex]\frac{1}{16}=k[/tex]
To find amount of saved money, we will substitute [tex]k=\frac{1}{16}[/tex] and [tex]x=448[/tex] in our equation.
[tex]y=\frac{1}{16}\cdot 448[/tex]
[tex]y=28[/tex]
Therefore, Charlie saved $28 in the given week.

Answers
1/2 = 0.5 as a decimal
0.5 ÷ 2 = 0.25
That means you walk 1 mile in 0.25 of an hour. Multiply this by three:
0.25 × 3 = 0.75
Answer:
It will take you 0.75 (or 3/4) hour to walk 3 miles.
__________________________________________
Write a proportion.
__________________________________________
[tex] \frac{(2) mi}{(0.5) h } = \frac{(3) mi.}{(x)h} [/tex] ;
Solve for "x" , [ (in units of "h"; (hours) ] ;
Note: "Cross-multiply" ;
Note: Given (a/b) = (c/d) ; → ad = ab ; (b ≠ 0 ; d≠ 0) ;
→ 2x = (0.5 * 3) ;
→ 2x = 1.5 ;
Divide each side of the equation by "2" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ 2x / 2 = 1.5 / 2 ;
to get:
→ x = 1.5 / 2 = 15/20 = (15÷5) / (20÷5) = 3/4 ;
or: → x = 1.5 / 2 = 15/20 = (15*5) / (20*5) = 75/100 = 75 ÷ 100 = 0.75 .

What is the solution set?
3.3x−11.6>18.1
Enter your answer in the box.
Please answer fast thanks!
Answers
The solution set is (9, ∞).
To solve the inequality 3.3x-11.6>18.1, we need to isolate the variable x.
First, we can add 11.6 to both sides of the inequality to get 3.3x>29.7.
Then, we can divide both sides by 3.3 to solve for x: x>9.
We can express the solution set using interval notation as (9, ∞).
Therefore, The solution set is (9, ∞).
The solution set for the inequality 3.3x - 11.6 > 18.1 is x > 9, meaning x is greater than 9.
To solve the inequality 3.3x - 11.6 > 18.1, you can follow these steps:
1. Add 11.6 to both sides to isolate the term with x:
3.3x - 11.6 + 11.6 > 18.1 + 11.6
3.3x > 29.7
2. Now, divide both sides by 3.3. Remember, when you divide by a positive number, the inequality sign remains the same:
[tex]\[ \frac{3.3x}{3.3} > \frac{29.7}{3.3} \][/tex]
[tex]\[ x > \frac{29.7}{3.3} \][/tex]
x > 9
So, the solution set for the inequality 3.3x - 11.6 > 18.1 is x > 9.

3x=-5y
6x-7y=17
Solve the equation
Answers
6x - 7y = 17 --------- (2)
From (1):
3x = -5y
x = -5/3 y ---------- sub into (2)
6 (-5/3 y) - 7y = 17
-10y - 7y = 17
-17y = 17
y = -1 ------------ Sub into (1)
3x = -5 (-1)
3x = 5
x = 5/3
Ans: x = 5/3, y = -1
Final answer:
To solve the system of equations, we first expressed x in terms of y from the first equation and substituted it into the second equation. After simplifying, we solved for y and then substituted back into the first equation to find x. The solution is x = 5/3, y = -1.
Explanation:
To solve the system of equations 3x = -5y and 6x - 7y = 17, one can use the method of substitution or elimination. We'll use elimination for this example. First, observe that the first equation can be rewritten to solve for x in terms of y:
3x = -5y
x = -5y/3
Let's substitute this expression for x into the second equation:
6(-5y/3) - 7y = 17
-10y - 7y = 17
-17y = 17
y = -1
Now substitute y back into the first equation to find x:
3x = -5(-1)
3x = 5
x = 5/3
The solution to the system of equations is x = 5/3, y = -1.
If you were given a rectangle with a certain area how would you draw it so that it had the greatest perimeter
Answers
Explanation:
The rectangle that has the greatest perimeter given a fixed area is the square.
So, take the square root of the area and draw a square with that side length.
The demostration of that is done using the optimization concept from derivative. If you already studied derivatives you can follow the following demostration.
These are the steps:
1) dimensions of the rectangle:
length: l
width: w
perimeter formula: p = 2l + 2w
area formula: A = lw
2) solve l or w from the area formula: l = A / w
3) write the perimeter as a function of w:
p = 2 (A / w) + 2w
4) find the derivative of the perimeter, dp / dw = p'
p' = - 2A / w^2 + 2
5) The condition for optimization is p' = 0
=> -2A / w^2 + 2 = 0
=> 2A / w^2 = 2
=> w^2 = A
Which means that the dimensions of the rectangle are w*w, i.e. it is a rectangle of side length w = √A
To maximize the perimeter of a rectangle with a given area, increase the length and decrease the width significantly.
To draw a rectangle with the greatest perimeter given a certain area, you should make the rectangle as long and narrow as possible. When the length of the rectangle approaches infinity and the width approaches zero while maintaining the same area, the perimeter is maximized.

The angles ∠2 = 135°, ∠3 = 135°, ∠4 = 45°, ∠5 = 45°, and ∠6 = 135° (all are in degrees)
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
The angle ∠1 = 45° is given. And the diagram is shown.
Types of the angles are as follows;
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.Vertically opposite angle - When two lines intersect, then their opposite angles are equal.Alternate angle - If two lines are parallel then the third line will make z -angle and z-angles are equal angles with the parallel lines.∠1 + ∠2 = 180° (Supplementary angle)
45° + ∠2 = 180°
∠2 = 135°
∠1 = ∠5 = 45° (Corresponding angle)
∠2 = ∠6 = 45° (Corresponding angle)
∠1 = ∠4 = 135° (Alternate angle)
∠2 = ∠3 = 135° (Alternate angle)

3. Quilt squares are cut on the diagonal to form triangular quilt pieces. The hypotenuse of the resulting triangles. Is 18 inches long. What is the side length of each piece?
4. Find the missing value to the nearest hundredth.
sin________=8/15
Answers
Question 3.
Answer: fourth option 9√2
Explanation:
1) Since the original quilt is square, you know that the diagonal length is the hypotenuse of the two triangles formed and it satifies this formula, derived from the Pythagorean theorem:
(diagonal) ^2 = (hypotenuse)^2 = 2 * (side length)^2
2) Solve for the side length:
(side length)^2 = (diagonal)^2 / 2
=> side length = √ [ (diagonal)^2 / 2 ] = diagonal * (√2) / 2
3) Substitute the diagonal length value:
side length = 18 * (√2) / 2 = 9√2
Question 4
Answer: second option 32.23°
Explanation
1) Given sin(angle) = 8 /15
2) To find the angle you have to use the inverse function, arcsin
angle = arcsin (8/15)
3) The calculator uses that function and the result that it gives is 32.23°.
To avoid confusions make sure that the calculator is in mode degrees.
I don’t know how to do it
Answers
This is the formula we'll use:
a²+b²=c²
Since it's a square, a and b are the same.
7²+7²=c²
49+49=c²
98=c²
√98=c
c=9.8995
So, the diagonal is 9.8995
9.8995<11
So, since the diagonal of the square is 9.8995 cm, it is less than the circumference of the circle meaning that it will fit in to the circle without touch the circle's circumference.
