-2.4 x 3 so sence there is one - symbole its ganna stay negitive and so we are first ganna do 3x4 whiych would be 12. So we would leave the 2 and carry the one and it should look like this. 1
-2.4
x3
-----------
0.2

Now multiply 3 by 2 and get 6 but add 1 sence we carried it so now it should be 7 and dont forget the negitive

There are currently 502 students at Hendrick Middle School. If that number is continuously
Alisiya [41]

Answer:

In the next 31 years

Step-by-step explanation:

In this question, we are tasked with calculating the number of years it will take for a school’s population to reach a certain amount of it is increasing at a certain rate.

We can use a mathematical exponential approach to solve this.

Let’s say;

P = I( 1 + r)^t

where P is the projected population at 926

I is the initial population at 502

r is the percentage change or rate at 2% which is same as 2/100 = 0.02

and t is time

Plugging these values, we have

926 = 502(1 + 0.02)^t

Divide through by 502

1.845 = 1.02^t

take the logarithm of both sides

log 1.845 = tlog 1.02

t = log 1.845/log 1.02

t = 30.9 = 31 years

Which two consecutive whole numbers would 341 be located?
marysya [2.9K]
The first number is 170
The second number is 171
Step-by-step explanation:
Let the first number be x^3 and the second number be x^3+1
The sum of the two is 341
X^3+x^3+1=341
2x^3+1=341
Substrate 1 from both sides
2x^3=341-1

A total of $4000 is invested: part at 8% and the remainder at 14%. How much is invested at each rate if the annual interest is $
skelet666 [1.2K]

Answer:

$2000 is invested at 8%

$2000 is invested at 14%

Step-by-step explanation:

A total of $4000 is invested part at 8% and the remainder at 14%

Annual interest is $440.

Simple interest formula;

I = P × R × T

Where I is the interest, P is the principal, R is the rate and T is the time.

P = $4000

R = 8% and 14%

T = 1 year

I = $440

Let's say $a is invested at 8% and;

$b is invested at 14%

Then,

($a × \frac{8}{100} × 1 ) + ($b × \frac{14}{100} × 1) = $440

and

$a + $b = $4000

This forms a simultaneous equation;

0.08a + 0.14b = 440 ... (i)

a + b = 4000 ... (ii)

Multiplying (i) by 1 and (ii) by 0.08  we get;

0.08a + 0.14b = 440 ... (i)

0.08a + 0.08b = 320 ... (ii)

Subtracting (i) - (ii) we get;

0 + 0.06b = 120

0.06b = 120

b = 120 ÷ 0.06 = 2000

So amount invested at 14% ($b) = $2000 and,

The amount invested at 8% ($a) = $4000 - $2000 = $2000
