Answer:
640 students
Step-by-step explanation:
We are told in the question that 4 out of every 5 students owns a bicycle
This also means , out of every 5 students only 1 does not have bicycle
Then we have a ratio of 4 : 1
This means a fraction of 4/5 students own a bicycle in a school
Based on this result, how many of the 800 students in a school own a bicycle?
This calculated as:
4/5 × 800
= 640 students
Therefore, 640 students out of 800 students own a bicycle

4. Factor x2 - 4x – 32.
Answer:
(x - 8)(x + 4)
Step-by-step explanation:
We need to find something that multiplies to 32 and adds up to 4.
The 2 special numbers would be -8 and 4.
-8(4) = -32
-8 + 4 = -4
We then simply write out the factored form:
(x - 8)(x + 4)
Answer: (x+4)(x-8)
Step-by-step explanation:
x^2 - 4x -32 Find two numbers that their product is -32 and their sum is -4. The numbers -8 and 4 will work out because -8 times 4 is -32 and -8 plus 4 is -4.
Now rewrite the whole polynomial as
x^2 +4x -8x -32 Now group them
(x^2 +4x) (-8x -32) Now factor each side
x(x +4) -8(x +4) factor out x+4
(x+4)(x-8)

Answer:
The answer is B. 0
Step-by-step explanation:
If the problem is d + (-d), then the answer is 0. Suppose that d = 7. Then it would be 7 + (-7), which is 0. You can't get any other number from that equation unless you do d + d or d - d.

Trey at most 6 hours to clean the offices.
If they work together, they will clean
1/4 + 1/6 = 5/12 of the offices.
Let x be the greatest amount of time it would take them to clean the offices together.
Thus,

This summer, Silvia has been selling lemonade for $9 per cup. If Silvia has sold 19 cups so far, how much money has she made?
Answer:
$171
Step-by-step explanation:
Price of lemonade = $9 per cup
Quantity sold = 19 cups of lemonade
Revenue = price of the product × quantity of the product sold
Silvia's total revenue = price × Quantity
= $9 × 19 cups
= $171
Silvia has made a total of $171 from selling 19 cups of lemonade at $9 each

The two figures below, a regular hexagon and a regular pentagon, have the same
perimeter. What is the length of a side of the pentagon?
Answer:
69
Step-by-step explanation:
Perimeter = sum of all sides of a regular polygon = the number of sides*length of a side
Length of a side of the given regular hexagon = 3x + 5
Perimeter of hexagon = 6(3x + 5) = 6(3x) + 6(5) = 18x + 30
Length of a side of the given regular pentagon = 4x - 1
Perimeter of pentagon = 5(4x - 1) = 5(4x) - 5(1) = 20x - 5
Since we are told that the perimeter of the regular hexagon is the same as that of the regular pentagon, therefore:
18x + 30 = 20x - 5
Solve for x.
Subtract 20x from both sides
18x + 30 - 20x = 20x - 5 - 20x
-2x + 30 = -5
Subtract 30 from both sides
-2x+ 30 - 30 = -5 - 30
-2x = -35
Divide both sides by -2
x = -35/-2
x = 17.5
Length of a side of pentagon = 4x - 1
Plug in the value of x
4(17.5) - 1 = 70 - 1 = 69
length of a side of the pentagon = 69
4.06/x = 0.18/0.5 please could you answer
Answer:
x=203/18
Step-by-step explanation:
convert the decimal into a fraction
203/50/x = 9/50 / 1/2
simply the complex fraction:
203/50x = 9/25
cross multiply
450x = 5075
divide both sides by 450:
x= 203/18
Answer:
X=11.2778
Step-by-step explanation:
4.06/X=0.18/0.5
cross multiply
0.18×X=4.06×0.5
0.18X=2.03
divide both sides by 0.18
0.18X/0.18=2.03/0.18
it becomes
X=2.03/0.18
X is therefore 11.2778

Answer: Slope = -7/5
=========================================================
Explanation:
Pick any two rows you want. I'll select the first two rows.
Each row represents an (x,y) point
The first row means (-8,55) is one point and the second row means (2,41) is another point.
Use these two points in the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (41-55)/(2- (-8) )
m = (41-55)/(2 + 8)
m = -14/10
m = -7/5 is the slope
The negative slope means the line goes downhill as you move from left to right.
Specifically, every time it drops 7 units the line moves over to the right 5 units.
slope = rise/run = -7/5
rise = -7, negative rise means we go down 7 spaces
run = 5 means we move to the right 5 spaces
