Compared to last year, the population has increased 25%. The population is now 6,600. What was the population last year?
What number of population do I put for each for percentage?
Answers
Answer:
4,950
Step-by-step explanation:
:)
1,650-25% 3,300-50% 4,950-75% 5,280-100%
Step-by-step explanation:
convert the percentage to a decimal then multiply by 6,600. To get the number of people of 100%, divide 1.25 (the percent of 6,600) by 6,600. That should be right,

AD = x cm.
BC is the same length as AD.
AB is twice the length of AD.
DC is 4 cm longer than AB.
The perimeter of the trapezium is 38 cm.
Work out the length of AD.
Answers
Perimeter implies the total length of sides of a given figure. Thus the length AD = 4.75 cm.
A plane figure is any type of figure bounded by four straight sides. Examples are square, rectangle, trapezium, rhombus, etc. A trapezium is a type of plane figure which belongs to a family referred to as quadrilaterals.
The perimeter of a given shape is the sum of the length of its boundaries or sides.
Thus the length AD required in the question can be determined by:
AD = x cm
BC = x cm
AB = 2x cm
DC = 4x cm
Perimeter = AD + BC + AB + DC
= x + x + 2x + 4x
Perimeter = 8x
But the perimeter of the trapezium has been given as 38 cm.
Thus,
38 = 8x
x = [tex]\frac{38}{8}[/tex]
= 4.75
Therefore, the length of AD is 4.75 cm.

I got 12 but my teacher said it was wrong? what's the right answer then?
Answers
Answer:
it is 12 but you probably didnt show our work
Step-by-step explanation:
Here is an example you can use:I multiplied 15 by .80 because I know that 4/5 is 80 of 100.
Answer:
0.12
Step-by-step explanation:
This is probably where you got confused
4/5% = 0.8%
-------------------------
15 / 10 = 1.5
1.5 / 10 = 0.15
0.15 / 10 = 0.015
or
15 / 1000 = 0.015
-------------------------
0.015 x 5 = 0.075
0.015 x 3 = 0.045
0.075 + 0.045 = 0.12
More Detailed Version
4/5 of 1% = 0.8%
0.8% is in the thousandths digit
15 / 1000 = 0.015
0.015 x 5 = 0.075
0.015 x 3 = 0.045
0.075 + 0.045 = 0.12

Answers
Answer:
-20%
Step-by-step explanation:
Current value of an item and divide it by the value from an earlier period. Subtract one and multiply the resulting number by 100 to give it a percentage representation.
ROC = (current value/previous value − 1) x 100
ROC = (1,000,000/1,250,000 - 1) x 100
ROC = (0.8 - 1) x 100
ROC = -0.2 x 100
ROC = -20

Let me know if you have any questionsIf a cheetah can travel 120 meters in just 4 seconds, then how many meter can it travel in 25 seconds?
Answers
Answer:
750 meters
Step-by-step explanation:
120 meters/4 seconds = 30 meters per second
30 meters per second * 25 seconds = 750 meters
(you could calculate 3 * 25 first to get 75 and then add the zero at the end. It's the faster way.)
Answer:
x = 750 m
Step-by-step explanation:
Write and solve a equation of ratios:
120 m 4 sec
------------- = -------------
x 25 sec
Inverting this equation yields
x 25 sec
-------------- = -------------
120 m 4 sec
Cross-multiplication yields (4 sec)x = (120 m)(25 sec). This yields:
3000 m-sec
x = -------------------- = 750 meters
4 sec
Note that the same result can be obtained by multiplying (120 m) by (25/4).

Noah receives a $5 discount each month on his cell phone bill because he signed up for
auto-pay from his bank account. Over the last 8 months, Noah has paid a total of
$280 for his cell phone bill. What would Noah be charged for his cell phone bill each
month if he stopped using auto-pay?
$34
$30
$35
$40
Answers
Answer:
Noah would pay $40 each month
The discount Noah received decreased the amount he pays by $5 every month.
Total discount in 8 months = 8 x $5 = $40
If Noah stopped using autopay, he would have to pay the full amount
Without the discount, the total amount Noah would pay in 8 months = amount paid without discount + total discount amount
$280 + $40 = $320
Amount Noah would pay per month = Total amount he pays in 8 months without discount / 8
$320 / 8 = $40

C. y - 9 = 2 (x + 3)
D. y + 9 = 2 (x + 3)

D
Step-by-step explanation:
First find the slope.
[tex]Slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{5-[-9]}{4-[-3]}=\dfrac{5+9}{4+3}\\\\\\=\dfrac{14}{7}=2[/tex]

y - y1 = m(x -x1)
y -[-9] = 2 (x - [-3])
y +9 = 2 (x + 3)
