A town has an annual growth rate of 2%. In 1970, the population was 250 people. What was its population in 2020?
Answer:
In 2020 the population would be 673.
Step-by-step explanation:
Giving the following information:
Current population (PV)= 250
Growth rate (g)= 2% annualy
Number of periods (n)= 2020 - 1970= 50 years
To calculate the number of people in 2020, we need to use the following formula:
FV= PV*(1+g)^n
FV= 250*(1.02^50)
FV= 672.89 = 673

Shelley's kitten weights 2 1/3 times as much as she did last year. She now weighs 21 ounces. What did the kitten weight a year ago?
Answer:
weight of the kitten last year = 9 ounces
Step-by-step explanation:
Let
x = weight of the kitten last year
Weight of the kitten this year = 2 1/3 * x = 21
7/3*x = 21
7/3x = 21
x = 21 ÷ 7/3
x = 21 × 3/7
= 63/7
x = 9 ounces
weight of the kitten last year = 9 ounces
Dan was thinking of a number. Dan subtracts 2.6 from the number and gets an answer of 72.8. Form an equation with
x
from the information.
Answer: x - 2.6 = 72.8
x is the number which Dan was thinking (x > 2.6)
we have:
x - 2.6 = 72.8

"a piece of machinery valued at $175,000 depreciates at 10% per year by the fixed rate method. After 12 years, what is the value of the machinery?"
Answer:
$49425.1688842
Step-by-step explanation:
Use formula: v=c*(p^t), where v is the price now, c is the cost price, p is the 100-the depreciation percentage and t is the time/years passed)
0.9¹²(175000)
0.28242953648(175000)
49425.1688842
Here are the first four terms in an arithmetic sequence.
1 4 7 10
Work out the 30th term in the sequence.
Answer:
88
Step By Step
Step-by-step explanation:
An arithmetic sequence is defined as
an=a+d(n-1) where an=nth term, a=initial term, n=term number, and d=common difference
For sequence 1,4,7... a=1 and d=4-1=7-4=3 so
an=1+3(n-1)
an=3n-2, so the 30th term is
an=3(30)-2
an=88

What is the equation of the line that passes through the point (8, 4) and has a slope
of 3/2?
Answer:
y = (3/2)x - 8 slope-intercept form
3x - 2y = 16 standard form
Step-by-step explanation:
Use the point-slope form of a line to do this problem.
[tex]y - y_{1} = m(x - x_{1} )\\[/tex]
In your case [tex](x_{1} , y_{1} ) = (8, 4)[/tex]
So. y - 4 = 3/2 ( x - 8)
multiply thru by 2
2y - 8 = 3(x - 8)
2y - 8 = 3x - 24
2y = 3x - 16
y = (3/2)x - 8 slope-intercept form
3x - 2y = 16 standard form

Answer:
Each game cost £3.75
Step-by-step explanation:
£13.75-£2.50=£11.25
£11.25÷3=£3.75
Answer:
Activity 1: 3g + 2.50 = 13.75
Activity 2: 3.75
Step-by-step explanation:
3g is because he played 3 games. You add 2.50 because that is also what Giovanni spent on. Equals 13.75 is because that's the total he payed.
To solve, first do - 2.50 from both sides. The new equation is 3g = 11.25. Now divide 3 from both sides to find g. g = 3.75. "g" is the cost of each bowling game. So the price of each bowling game is 3.75.
Hope it helps!

2x +3y = 9
-3x +3y = -6
Rewrite the second equation:
This is to make the calculation easier. There are other ways to do this as well.
3y = 3x - 6
Substitute that into the first equation:
Since they are the same thing (=), it is possible to replace 3y.
2x + (3x - 6) = 9
Solve the equation:
2x + 3x = 9 + 6
5x = 15
x = 3
Substitute x = 3 into the first equation:
2(3) + 3y = 9
6 + 3y = 9
3y = 3
y = 1
Answer: x = 3, y = 1
Solve x = 5x + 6.

Choose the polynomial that is written in standard form.
a. x + 4x5 + 10x3
b. x4 + 4x2 + 8x
c. −9x4 + 4x6 + 10x2
d. x4 + 4x4 + x6
Answer:
b. x^4 + 4x^2 + 8x
Step-by-step explanation:
I took the test. Also the exponents need to be in descending order in order for the equation to be in standard form.
So b, starts with an exponent of 4, the decreased to just the x variable with an understood exponent.
Decreasing -> 4,2,(1)

Answer:so that’s a interior triangle so the mean your 2 points in the inside and the equation on the outside.
X=6
Step-by-step explanation:
(8x-4)+(3x+17)=(17x-23)
Combined our alike terms on the left side of the equation. So 8x+3x and -4+17.
11x+13=17x-23
Now this is what the equation should look like after combining ur alike terms.
11x+13=17x-23
-11x. -11x.
now u take the lowest x which is 11x and mince that from 17x but u only mince if it’s a positive but is it’s a negative u add it.
13=6x-23 so if u moved the x on the right side u move non variable number to the left but if u moved the x to the left u move the non variable number to the right so in this case the non variable number would be -23 so now u add 23 on both sides.
36=6x and now u just divide the 36 by 6 and remember to always divide by the x
Now the answer is x=6
