As the owner of a pastry shop, you decide to have a sale on brownies. You price each brownie at 37 cents. At the end of the sale, you have sold 10 trays of brownies, with 12 brownies in each tray.
How much money did you receive from selling the brownies?
Answer:
4440
Step-by-step explanation:
10×12= 120 so you would 120 brownie.
so 120 × 37 for each is 4440 so your answer would be 4440. I used desmos.com, it is very helpful. You should give it a try!
Answer:
$44.40
Step-by-step explanation:
Each tray has 12 brownies, And you sold 10 trays
calculate total amount of brownies

A full-time employee who works 40 hours per week earns $20.50 per hour. Estimate that person's income. Round 52 weeks to 50 weeks per year, and round the hourly wage to the nearest dollar for the estimate. What is the estimated of annual income?
Given :
Full-time employee who works 40 hours per week earns $20.50 per hour.
To Find :
The weekly income and annual income after round off .
Solution :
Weekly income is given by :
[tex]C =40\times 20.50\\\\C=\$ 820[/tex]
Now , round off of hourly in come to nearest dollar is $21 .
So , new weekly income is :
[tex]C'=40\times 21\\\\C'=\$ 840[/tex]
Now , annual income is :
[tex]A=C'\times 50\\\\A=\$840\times 50\\\\A=\$42000[/tex]
Therefore , weekly income and estimated of annual income is $42000 .
Hence , this is the required solution .

What is the solution to this equation?
-8x + 4 = 36
O A. x= -4
O B. x = 4
O c. x= -5
O D. x = 5
Answer:
A
Step-by-step explanation:
So we have the equation:
[tex]-8x+4=36[/tex]
Subtract 4 from both sides:
[tex]-8x=32[/tex]
Divide both sides by -8:
[tex]x=-4[/tex]
And we're done!
The answer is A
Answer:
A. x = -4
Step-by-step explanation:
We are given the equation:
-8x+4=36
We want to solve for x. Therefore, we must isolate x on one side of the equation.
4 is being added to -8x. The inverse of addition is subtraction. Subtract 4 from both sides of the equation.
-8x+4-4=36-4
-8x=36-4
-8x=32
x is being multiplied by -8. The inverse of multiplication is division. Divide both sides of the equation by -8.
-8x/-8=32/-8
x= 32/-8
x=-4
Let’s check our solution. Plug -4 in for x and solve.
-8x+4=36
-8(-4)+4=36
32+4=36
36=36
This checks out, so we know our solution is correct.
The solution to the equation is A. x=-4

Compare and contrast the following diagrams by creating a list of at least
five complete sentences.
Answer:
The similarities are
1) Both diagrams consists of an horizontal line l for the upper diagram and k for the lower diagram
2) Both diagrams have a vertical plane Z for the upper diagram and A for the lower diagram
3) Both diagrams have rays, which are C for the upper diagram and G and H for the lower diagram
The differences are
1) The upper diagram has only one plane, while the lower diagram has two planes, seemingly rotated at an angle of about 90° to each other
2) The upper diagram has only one line, l, while the lower diagram has two lines, l and GH

Edward has deposited $847 in a savings account that earns interest at a rate of 2.2% compounded daily. What will the account balance be in 18 years
Answer:
$1,257.63
Step-by-step explanation:
A= p(1+r/n)^nt
P = principal = $847
r= interest rate = 2.2%
n= 360 per year
t= 18 years
A= p(1+r/n)^nt
= 847(1+0.022/360)^360*18
= 847(1+0.000061)^6,480
= 847(1.000061)^6,480
=847(1.4848)
= $1,257.63
Total balance in 18 years = $1,257.63

Given that 2 x − 2 y = 23 Find x when y = 9
Answer:
[tex]x=41/2=20.5[/tex]
Step-by-step explanation:
So we have the equation:
[tex]2x-2y=23[/tex]
And we want to find x when y is 9.
So, substitute y for 9 and solve for x:
[tex]2x-2(9)=23[/tex]
Multiply:
[tex]2x-18=23[/tex]
Add 18 to both sides:
[tex]2x=41[/tex]
Divide both sides by 2:
[tex]x=41/2=20.5[/tex]
So, our answer is 20.5
Answer:
20.5
Step-by-step explanation:
2x - 2y = 23
2x - 2(9) = 23
2x - 18 = 23
2x = 23 + 18
2x = 41
x = 20.5
Can someone explain how to do this?
Answer:
ok so basically the points need to be graphed on a map and to do that you need to know the x and the y axis.x axis is horizontal and y is verticle.So look at -3,-5 the x is -3 and the y is -5 so you go left -3 and then down -5

Which equation has the solution x = 6? One-sixth x = three-fourths x + 2 One-fourth x + one-half = one-third x One-half x + 3 = three-fifths x + 3 Four-fifths x minus 1 = three-fourths x
Answer:
x = 6
One-fourth x + one-half = one-third x
Step-by-step explanation:
1/4 x + 1/2 = 1/3 x

A 525 gram rock contains 25.0% gold.How many grams are gold?
Answer:
131.25 gram is gold
Step-by-step explanation:
Rock = 525 gram
Gold = 25.0% of the rock
To determine how many grams of the rock are gold,
Find 25.0% of 525 gram
= 25/100 × 525
= 0.25 × 525
= 131.25 gram
Gold = 131.25 gram of the rock
Therefore,
131.25 gram of the rock is gold

The width of a rectangle measures (4.4d-4.3)(4.4d−4.3) centimeters, and its length measures (7.6d+4.7)(7.6d+4.7) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer:
Perimeter, P = (24d+0.8) cm
Step-by-step explanation:
Given that,
Width of rectangle, B = (4.4d−4.3) cm
Length, l = (7.6d+4.7)
Perimeter is equal to the sum of all sides. A rectangle have 4 sides. The opposite sides of a rectangle are equal. So,
Perimeter = 2(L+B)
P = 2[(7.6d+4.7)+(4.4d−4.3)]
Collecting like terms
P = 2[(7.6d+4.4d)+(4.7−4.3)]
P=2(12d+0.4)
⇒ P = 24d+0.8
So, the expression for the perimeter of the rectangle is (24d+0.8) cm.

If six times a number is decreased by fourteen, the result is 124. What is the number
Answer:
[tex]\large\boxed{23}[/tex]
Step-by-step explanation:
Six times a number is decreased by fourteen, the result is 124.
Write an equation that represents this
(6 * x) - 14 = 124
Multiply 6 by x to remove the parenthesis
6x - 14 = 124
Add 14 to both sides of the equation
6x = 138
Divide both sides of the equation by 6
x = 23
The unknown number is [tex]\large\boxed{23}[/tex]
Hope this helps :)
Answer:
138
Step-by-step explanation
6x-14=124
6x=124+14
x=138/6 138/6=23
X=23
