Bruce owns a business that produces widgets. He must bring in more in revenue than he pays out in costs in order to make a profit. • It costs $10 in labor and materials to make each of his widgets. • His rent each month for his factory is $4,000. He sells each widget for $25. What is the smallest number of widgets Bruce needs to sell each month to make a profit?
Answer:
Bruce needs to sell 267 widgets each month to make a profit.
Step-by-step explanation:
From the information given, you can write that the cost of the monthly rent plus the cost in labor and materials to make each widget for the number of widgets is equal to the amount of sales:
10x +4000 = 25x
Now, you can solve for x:
4000 =25x-10x
4000=15x
x= 266.67→267
According to this, the answer is that Bruce needs to sell 267 widgets each month to make a profit.

Answer:
1 71/72
Step-by-step explanation:
1 7/8 + 1/9 = 1 + 7/8 * 9/9 + 1/9 * 8/8 = 1 + 63/72 + 8/72 = 1 + 71/72 = 1 71/72
Solve for the letter A. ab+d=c
Answer:
a=c/b-d/b
Step-by-step explanation:
Answer:
a=c-d/b
Step-by-step explanation:
We first need to isolate the variable "a" by doing the opposite operation.
1. subtract "d" on both sides
After step 1- ab=c-d
2. divide both sides by "b" because that is the only way to isolate a permanently
After step 2- a=c-d/b

HELP!!!!!!!!!!!!!!!!!!!!!!!
Answer:
79
Step-by-step explanation:
m<1 = 90 -38 = 52
m<3 = 90 - 52 = 38\
m<2 = 180-38-63 = 79
Answer:
Step-by-step explanation:
<1 + <3 = 90 Parallel lines produce interior angles that add to to 90
<1 + 38 = 90 Substitution
<1 = 90 - 38 52
<3 = 90 - 52
<3 = 38
38 + 63 + <2 = 180 Sum of angles in a triangle always = 180
101 + <2 = 180
<2 = 79

1. Write a paragraph proof for the following conjecture.
Given: QS bisects ∠PQR.
m∠PQS = 45°
.
Prove: []PQR is a right triangle.
10 points, help asap
QS bisects the ^PQR^ :
So -----¢ PQS = SQR = 45°
_________________________________
PQR = PQS + SQR = 45°+ 45° = 90 °
Q^ = 90° ----¢ So the PQR triangle is a
right triangle.
Which statement that describes show that figure a is congruent to figure b
Answer:
E.
Step-by-step explanation:
Translation: slide of the shape or figure, it does NOT change its shape, size, and form, count how many units the shape moves.
Reflection: flip of the shape, does NOT change its shape, size, and form, either can be flipped or reflected over the x or y axis.
Rotation: turn of the shape, does NOT change its shape, size, and form, either can be rotated counter clock wise left, (opposite of a clock direction), or clockwise, the direction a clock moves right. It can also be rotated 90° (1 turn), 180° (2 turns), 270° (3 turns) or 360° (4 turns). In highschool, you will get introduced to more degrees of rotation, this is just middle school level.

what is the slope of the line 3y-x=-6
Write the equation of the piecewise function. Algebra 2
Answer:
C. [tex]y=\begin{cases}2-x&x<0\\5-3x&x\ge 0\end{cases}[/tex]
D. [tex]y=\begin{cases}-2&x<-3\\4&x>-3\end{cases}[/tex]
Step-by-step explanation:
C. The line to the left of x=0 has a slope of -1 and a y-intercept of 2. That portion of the function does not include x=0. The line to the right of x=0 has a slope of -3 and a y-intercept of 5. That portion of the function includes the case x=0.
[tex]\boxed{y=\begin{cases}2-x&x<0\\5-3x&x\ge 0\end{cases}}[/tex]

Solve for x.
50x + 54 = 34x + 46
Answer:
x = -1/2
Step-by-step explanation:
50x + 54 = 34x + 46
Subtract 34x from each side
50x-34x + 54 = 34x-34x + 46
16x +54 = 46
Subtract 54 from each side
16x+54-54 = 46-54
16x = -8
Divide by 16
16x/16 = -8/16
x = -1/2
Answer:
[tex]x=-\frac{1}{2}[/tex]
Step-by-step explanation:
So we are given an equation and we are asked to solve for x.
50x + 54 = 34x + 46
Subtract 54 from both sides.
50x = 34x - 8
Subtract 34x from both sides.
16x = -8
Divide both sides by 16.
[tex]x=-\frac{1}{2}[/tex]
So now we have solved for x. We have found that [tex]x=-\frac{1}{2}[/tex].

To measure a stone face carved on the side of a mountain, two sightings 700 feet from the base of the mountain are taken. If the angle of elevation to the bottom of the face is 35 and the angle of elevation to the top is 38 , what is the height of the stone face?
Iet us say we have two right triangles. With a base of 700. The first has angle of 35o and the other has an angle of 38degree
Then we need the Height
From trigonometry
Tan = opposite/adjacent.
In this case the adjacent is 800
Tan 35 = 0.7002
