Answer:
The equation that models the population growth is y = 90,000(1.02)^x
Step-by-step explanation:
The formula of the exponential growth is y = a [tex](b)^{x}[/tex], where
a is the initial valueb is the factor of growth ⇒ b > 1Let us solve the question
∵ At x = 0, the population y = 90,000
→ That means the initial value is 90,000
∴ a = 90,000
→ Substitute it in the form of the equation above
∴ y = 90,000 [tex](b)^{x}[/tex]
→ To find b use any values from the table to substitute x and y
∵ At x = 1, y = 91,800
∵ 91,800 = 90,000 [tex](b)^{1}[/tex]
∴ 91,800 = 90,000 b
→ Divide both sides by 90,000
∵ [tex]\frac{91,800}{90,000}[/tex] = [tex]\frac{90,000b}{90,000}[/tex]
∴ 1.02 = b
→ Substitute it in the equation above
∵ y = 90,000 [tex](1.02)^{x}[/tex]
∴ The equation that models the population growth is y = 90,000(1.02)^x

increase 400litres by 20%
Answer:
480 Litres
Step-by-step explanation:
Percentage increase = 20% × 400
New value =
400 + Percentage increase =
400 + (20% × 400) =
400 + 20% × 400 =
(1 + 20%) × 400 =
(100% + 20%) × 400 =
120% × 400 =
120 ÷ 100 × 400 =
120 × 400 ÷ 100 =
48,000 ÷ 100 =
480
Shane rode his bike for two hours and traveled 12 miles at this rate how long would it take him to ride 22 miles
Answer:
3.66666666667
Step-by-step explanation:
First, we need to find the unit rate to figure out how many miles Shane rides in 1 hour. To do this it is simple, I divided 12 and 2 to get 6 miles per hour. Then we would do 22/6 but we get a decimal so it would be about 3.66666666667.

To find:
The congruent angles and sides, then find the another valid congruency statement.
Solution:
We have,
[tex]\Delta ABE\cong \Delta MNP[/tex]
We know that, corresponding parts of congruent triangles are congruent (CPCTC).
Using CPCTC, we get

The value of a bank account is −$28. Money is then deposited into the account. Which could represent the value of the account now? A.-$33 B.-$6 C.-$45 D.$17 E.$0
Answer:
Step-by-step explanation:
depends how much money is deposited, however, the choices can be just D or E
Answer:
B,D,E
Step-by-step explanation:
Does it say how much was deposited? Ok so deposit means your bank gets bigger so it cannot be less than -28.
My guess is that it will be either B,D,E
The reason I say my guess is because I think the question should have given you an amount of how much was deposited.

John jogged 4.5 miles on Thursday, 7 2/5 miles on Friday, and 10.4 miles on Saturday. How many miles does John have to run in order to run 25 miles for the week
im giving 20 points
Answer:
2.7 miles
Step-by-step explanation:
25 - 10.4 - 4.5 - 7 2/5 will give you 2.7
Answer:
8 miles
Step-by-step explanation:
If we divide 70 by 50, we get the unit rate for the ratio 70 minutes for every 50 miles.
70÷50=1.4
So the runner is running 1.4 minutes per mile. We can multiply this unit rate by the number of miles:
1.4 minutes mile × 5 miles = 7 minutes
Thus it will take her 7 minutes to run 5 miles at this pace.
If it takes her 7 minutes to run 5 miles, it will take her 7÷5 = 1.4 minutes to run 6÷3=2 miles at the same pace.
If it takes her 1.4 minutes to run 5 miles, it will take her 1.4×5=7 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.
We found her pace in minutes per miles in part (a).
