Answer:

2221

Step-by-step explanation:

<h3><u>1st Digit</u></h3>

To find the scale factor, divide one side of the larger shape by the corresponding side of the smaller shape.

⇒ 16 ÷ 4 = 4

Answer = 4

Therefore, 1st digit = 2

--------------------------------------------------------------------------------------------------

<h3><u>2nd Digit</u></h3>

<u />

$\dfrac{x}{5}=\dfrac{12}{10}$

Cross multiply:

$\implies 10x=60$

Divide both sides by 10:

$\implies x=6$

Answer = 6

Therefore, 2nd digit = 2

--------------------------------------------------------------------------------------------------

<h3><u>3rd Digit</u></h3>

$\dfrac{5}{3}=\dfrac{12.5}{x}$

Cross multiply:

$\implies 5x=37.5$

Divide both sides by 5:

$\implies x=7.5$

Answer = 7.5

Therefore, 3rd digit = 2

--------------------------------------------------------------------------------------------------

<h3><u>4th Digit</u></h3>

XY ~ OM

XZ ~ ON

YZ ~ MN

Answer = YZ

Therefore, 4th digit = 1

1.The growth of a sample of bacteria can be modeled by the function b(t)=100(1.06)t where b is the number of bacteria and t is t

qwelly [4]

Given:

The growth of a sample of bacteria can be modeled by the function

$b(t)=100(1.06)^t$

where, b is the number of bacteria and t is time in hours.

To find:

The number of total bacteria after 3 hours.

Solution:

We have,

$b(t)=100(1.06)^t$

Here, b(t) number of total bacteria after t hours.

Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.

$b(t)=100(1.06)^3$

$b(t)=100(1.191016)$

$b(t)=119.1016
$

Therefore, the number of total bacteria after 3 hours is 119.1016.

Solve the inequality 14 + 10y >= 3(y + 14)

Brrunno [24]

14+10y > 3(y+14)

14+10y > 3y + 42
-3y -3Y

14 + 10y - 3y < 42

-14 -14

10y - 3y >42 - 14

7y > 28

Y> 4

Kamil invests 9000 for 4 years his investment pays compound interest of x% per anumn

elena-s [515]

To get the Total amount upon investment for the compound interest, plug in the value of x into the given expression bellow

Given data

Principal = $9000

Time = 4 years

Rate = x% per annum

<h3>Solution</h3>

Step one:

First, convert R as a percent to r as a decimal

r = x/100

Step two:

Then solve the equation for A

A = P(1 + x/100)^t

A = 9,000.00(1 + x/100)^(4)

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $9,000.00 at a rate of x% per year.
