What's the next number? 12 21 23 32 34 43

Answers

Answer 1

Answer: The correct answer is 45. The rule to the numbers is x + 9 and then x + 2.

12 + 9 = 21
21 + 2 = 23
23 + 9 = 32
32 + 2 = 34
34 + 9 = 43
43 + 2 = 45

Hope this helps!

A bus travels 36 miles in 45 minutes. enter the total numbet of miles the bus travels in 60 minuted at this rate.

Answers

A rate is a special ratio in which the two terms are in different units. A rate is a little bit different than the ratio, it is a special ratio. For this case, the rate would have units of miles per minutes. We calculate as follows:

rate = 36 miles / 45 min = 0.8 miles per min
distance traveled = 0.8 miles per min ( 60 min ) = 48 miles

Hope this answers the question. Have a nice day.

0.8 miles per minute

0.8miles/minutes/60 minutes =45 minutes

The area of a circle is 9pi square meters. What is the circumference?

Answers

circumference of a circle=2πr

area=πr²

1) we calculate the radius of this circle.
Data:
area=9π m²
area=πr²

9π m²=πr²
r²=9π m² / π
r²=9 m²
r=√(9 m²)=3 m

2) we calculate the circumference:
circumference=2πr=2π(3 m)=6π m

Answer: the circumference is 6π m

An investment account earns 4% per year compounded annually if the initial investment was $4000 how much is the account after three years? Round your answer to the nearest dollar

Answers

The amount will be $4499.45 if an investment account earns 4% per year compounded annually if the initial investment was $4000.

What is compound interest?

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

$\rm A = P(1+(r)/(n))^(nt)$

Where A = Final amount

P = Principal amount

r = annual rate of interest

n = how many times interest is compounded per year

t = How long the money is deposited or borrowed (in years)

It is given that:
An investment account earns 4% per year compounded annually if the initial investment was $4000.

P = 4000

r = 4% = 0.04

t = 3

n = 1

Plug all the values in the formula, and we get:

A = 4000(1 + 0.04)³

A = $4499.45

Thus, the amount will be $4499.45 if an investment account earns 4% per year compounded annually if the initial investment was $4000.

compounded annualy makes it easier
$A=P(1+r)^t$
A=future amount
P=present amount
r=rate in decimal
t=time in years

given
P=4000
r=4%=0.04
t=3

$A=4000(1+0.04)^3$
$A=4000(1.04)^4$
A=4499.456
round

about $4499 in the account after 3 years
