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
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 .
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.

-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
what is the domain and range of the graph
Answer:
both are "all real numbers"
Step-by-step explanation:
The graph appears to be of a cubic polynomial (degree 3). Any polynomial has a domain of "all real numbers."
Any odd-degree polynomial has a range of "all real numbers."
Both the domain and range are "all real numbers", (-∞, ∞).

6i - 54 > 6 (3 - 2i)
Answer:
i > 4
Step-by-step explanation:
6i - 54 > 6 (3 - 2i)
6i - 54 > 18 - 12i
6i + 12i > 18 + 54
18i > 72

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

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
10 × 12 = 120 brownies
37 cents = 0.37
multiply them together
120 × 0.37 = 44.40
Thus, you recieve 44.40

Tom made a square measuring 8 feet by 8 feet, and had 18 friends stand inside it as if they are watching a band at a small club. Find the ratio of this number to the rectangle’s area. Choose the appropriate label for this ratio.
Answer:
The ratio of this number to the rectangle’s area is 9:32.
Step-by-step explanation:
The information provided are:
Tom made a square measuring 8 feet by 8 feet.He had 18 friends stand inside it as if they are watching a band at a small club.The area of the square is:
A = (side)²
[tex]=(8\ \text{feet})^{2}\\\\=64\ \text{feet}^{2}[/tex]
The number of people standing insider the square is:
n = 18
Compute the ration of n to A as follows:
[tex]n:A=18:64[/tex]
[tex]=\frac{18}{64}\\\\=\frac{9}{32}\\\\=9:32[/tex]
Thus, the ratio of this number to the rectangle’s area is 9:32.
