Answer:
L=8
Step-by-step explanation:
area of a rectangle = length x width
given:
area= 20 square units
width =2.5 units
find the length by substituting :
20=2.5 x L
L= 20/2.5=8
that's it :)

What is the area of triangle AOB? *picture attached* show work also please
Answer:
The area of the traingle AOB is 30 (Rounded up result)
Step-by-step explanation:
7.8 cm and 10 cm.
10/2= 5 cm
Then Reversed Pitagora's Formula:
Square root of the calc "(7.8^2)-(5^2)" = 60,84 - 25 = 35,84
Then Square root of 35, 84 is 5,98.
5.98 is the height of the triangle AOB
With the height we can calculate the area
We use the formula (B*H)/2
So is (10*5,98)/2, that makes 29,9
Just round up to 30 and that's the area.

a small ball floats on the surface of the water
Answer:
what type of ball ;)
Step-by-step explanation:
Simplify the expression
Solve the equation for m:
2m +4
———— = W
8
A. m = 4w - 2
B. m = 4w - 8
C. m = 2w - 4
D. m = 8w-4
Answer:
2m +4 =8w
2m = 8w -4
m=8w-4 / 2
m= 4w - 2
therefore, option A is the answer.
Solve for k. -9 - 9k = -27
______________________________
1.) Add 9 to both sides:[tex]-9+9=[/tex] Cancels Out[tex]-27+9=-18[/tex]
- We subtract because we need to get the variable on one side and one number on each side of the equals. To do this you must do the opposite of what you see, (We have -9, so we do +9) on each side.
Equation at the end of Step 1:
[tex]-9k=-18[/tex]2.) Divide both sides by −9:[tex]-9k[/tex] ÷ [tex]-9=k[/tex][tex]-18[/tex] ÷ [tex]-9=2[/tex]- We multiply because we need to get k alone with 1 number left over. To do this you do the opposite of what you see, (We have -9 and k being multiplied, we divide them by -9) on each side.

if there's 130 calories in 3/4 cup how many calories are in 1/4 cup
Answer:
your answer would be 130/3
Step-by-step explanation:
By a simple rule of 3, we will see that in 1/4 cup there are 43.33 calories.
Using the rule of 3.
We know that in 3/4 cup there are 130 calories, then we can write:
3/4 cup = 130 calories.
We want to know how many there are in 1/4 cup, let's say that there are X, then we can write:
1/4 cup = X
If we take the quotient of the two equations we get:
(3/4 cup)/(1/4 cup) = (130 calories)/X
Solving this for X we get:
3 = (130 calories)/X
X = (130 calories)/3 = 43.33 calories
So we can conclude that in 1/4 cup there are 43.33 calories.

In May, Yoder's Bookstore had sales of $5,000, cost of goods sold of $3,000,
operating expenses of $800, and taxes of $400. Calculate Yoder's gross profit and final
net income or loss.
Please answer this for me! Thank you ;)
Answer:
This reminds of gta but the answer is that Yoder's profit is 800 dollars
Step-by-step explanation:
5,000 - 3,000 - 800 - 400 = 600
Answer: The net or gross profit made by Yoder's Bookstore is $800 .
Step-by-step explanation:
The income statement records the entire revenues and total costs.
The business makes money if its overall revenues exceed its whole expenses.
Additionally, the business will experience a net loss if its overall sales fall short of its total expenses.
The retained earning account statement would show this net income or net loss.
In order to calculate the gross income, the sales amount must first be subtracted from the cost of the goods sold.
Total sales done by Yoder's Bookstore = $5,000
Total cost of sold goods = $3,000
Operating expenses beared by Yoder's Bookstore = $800
Taxes paid by Yoder's Bookstore = $400.
Gross profit earned by Yoder's Bookstore =
$5,000 - ($3,000+$800+$400)
Net profit earned by Yoder's Bookstore = $5000 -$4200 = $800
Hence, the net or gross profit made by Yoder's Bookstore is $800 .

If the perimeter of a square is 120f+80 inches, what is the length, in inches, of each side of the square?
Answer:
30f + 20
Step-by-step explanation:
A square has four sides, all of equal length. If we call that side length x, then the perimeter - the total length around the square - is 4x. To find the side length given the perimeter then, we can simply divide the perimeter by 4.
Our perimeter here is 120f + 80, and dividing each term by 4 gives us a side length of 30f + 20.

- 7x-2y=-13
x - 2y = 1
Solve by substitution
multiply and subtract and do the x y across
Answer:
y = 3/8, x = 7/4
Step-by-step explanation:
x = 2y+1
-7(2y+1) - 2y = -13
-14y - 7 - 2y = -13
-16y - 7 = -13
-16y = -6
y = 3/8
Plug the value for y into one of the equations to solve for x

Which calculation and answer show how to convert 3/12 to a decimal
Plz help ASAP
Answer:
Its C
Step-by-step explanation:
It is C becuase when converting a fraction to a decimal, you just divide the numerator by the denominator
Basically solve the fraction
3/12=1/4
1/4 is a bencmark so right away you should know that should equal to 0.25 since its a quarter.
Or you can always look it like this
3 is the numerator
the “/“ between is basically ”divided by”
And the 12 is the denominator
Now read the equation in that order
3/12= 3 DIVIDED BY 12
