Answer: below(=
Step-by-step explanation: Given that,
dimensions of wall = 8.3ft by 7.5ft
height of wall = 8.3
width of wall = 7.5
there are total 3 walls in a bedroom to be painted blue.
Formula to calculate area of one wall
Height x Width
Formula to calculate area of four walls
3 (Height x Width)
= 3( 8.3ft x 7.5ft)
= 3 (62.25 ft²)
= 186.75 ft²
So area Alyssa will paint = 186.75 ft²

The Mad Hat Company must ship two different-sized boxes: The small ones cost them 45 cents each and weigh 6 ounces, and the large ones weigh 25 ounces and cost $1.20 each. The total shipment this morning weighed 20 pounds 7 ounces and cost $18.45. How many packages of each size were shipped?
Given :
The Mad Hat Company must ship two different-sized boxes: The small ones cost them 45 cents each and weigh 6 ounces, and the large ones weigh 25 ounces and cost $1.20 each.
The total shipment this morning weighed 20 pounds 7 ounces and cost $18.45.
To Find :
How many packages of each size were shipped.
Solution :
We know, 1 pound = 16 ounces.
So, 20 pound = 20×16 = 320 ounces.
Let, number of large and small box are l and s.
So,
25l + 6s = 327 ...1)
0.45s + 1.20l = 18.45 ...2)
Solving both the equations, we get :
x = 9 and y = 17
Therefore, package smaller and big size are 17 and 9 respectively .
Hence, this is the required solution.
what is 90% of 20????
Answer:
18
Step-by-step explanation:
Multiply 20 by 0.90 (that is 90%)
18 is the answer
Hope this helps :)
Answer:
18
Step-by-step explanation:
Hello there. This problem can be easily solved by setting up a ratio.
This would be as follows
[tex]\frac{90percent}{100}[/tex] x [tex]\frac{x}{20 }[/tex]
after solving for x we find that 90% of 20 should be 18.
Hope this helps!

What is the inverse of the function g(x)=5(x-2)g(x)=5(x−2)g, left parenthesis, x, right parenthesis, equals, 5, left parenthesis, x, minus, 2, right parenthesis
Answer:
(x+10)/5
Step-by-step explanation:
Given the function
g(x) = 5(x-2)
Open the parenthesis
g(x) = 5x-10
To find the inverse we need to follow the steps;
Step 1; make y as g(x)
y = 5x-10
Step 2; replace y with x;
x = 5y - 10
Step 3; make y the subject of the formula;
x = 5y-10
5y = x+10
y = (x+10)/5
Step 4: substitute y as g^(-1)(x)
g^(-1)(x) = (x+10)/5
Hence the inverse of the function is (x+10)/5
Answer: x+10/5
Step-by-step explanation:
Same as above

Alex is thinking of a number. Twenty less
than one fourth of the number is -45. Find Alex’s number.
i need the equation.
Answer:
¼x - 20 = -45
¼x = -25
x = -100
Step-by-step explanation:
To solve this we can write it out into an equation. Let's use the variable x for the number Alex is thinking of. Then we can take out each information to see what it means mathematically. We need to see what operation is being done.
"twenty less than one fourth of the number" The second part is using mutiplication, as indicated by "of." So we would write a quarter (one fourth) times the number (x). The first part is using subtraction, indicated by "less than." This would be expressed by "- 20"
Putting it together:
¼x - 20
"is -45" this is joining the expression to an equation. So this would simply mean " = -45 " Then our equation is:
¼x - 20 = -45
Now we can solve it.
¼x - 20 = -45
¼x = -25
x = -100
Simplify
-4x+2x2-x2+5-3x
Answer:
9 - 7x - x²
Step-by-step explanation:
-4x+2x2-x²+5-3x = -4x-3x+2x2+5-x²
I arranged the like terms together so it is easier to do the calculations.
-4x-3x+2x2+5-x² = -7x+4+5-x²
Simplify.
-7x+4+5-x² = 9-7x-x²
Answer:
[tex]x^{2} -7x+5[/tex]

Then combine like terms: [tex]x^{2} -7x+5[/tex]
ermest works in the shipping department loading shipping crates with boxes. Each empty crate weighs 150 lb. How many boxes, each weighing 35 lb, can Ernest put in the crate if the total weight is to be no more then 850 lb?
Max weight of the crate - the empty crate/ by 35 (the weight of the individual boxes)
850-150=700
700 lbs is the remaining weight available that can be filled with 35 lb boxes, to find out the number of boxes that can be added to the crate, divide 700 by 35.
700/35 = 20
Ernest can put in 20 boxes in the crate.
Please give me an explanation too I need help Solve for y: 2x-y=3
Answer:
y = 2x -3
Step-by-step explanation:
to solve for y, simply isolate the y so in this case move 2x to the right side of the equation in which it becomes -y= -2x +3 and then divide by -1 which is beside the -y essentially cause y cannot be negative so then the equation becomes y = 2x -3
Answer:
y=2x-3
Step-by-step explanation:
2x-y=3
-2x on both sides of the equal sign which leaves you with -y=-2x+3
divide both sides by negative 1
y=2x-3

When an item is marked up by a certain percent and then marked down by the same percent, is the sale price equal to the price before the markup and markdown? Explain.
Answer:
Step-by-step explanation:
For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises. A computer software retailer used a markup rate of 40%.

Answer:
Step-by-step explanation:
x=64 degrees
y=52 degrees
It is an isosceles triangle which has two angles of the same measurement, Pretty easy to figure out.
Answer:
x= 64 ansdy=52
Step-by-step explanation:
Since the 64 line is congruent to the "x" line, it must be 64. A triangle's angles equal 180 so 180-64-64= 2 giving you "y"
