Find the scale factor where the pre-image is the small triangle and the image is the large triangle.

Oduvanchick [21]

Answer:

The scale factor is $\frac{9}{7}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

$\frac{18}{14}=\frac{27}{21}=\frac{9}{7}$

therefore

The scale factor is 9/7

Find the value of x

The value of x is equal to

$\frac{x}{28}=\frac{9}{7}$

$x=28(\frac{9}{7})=36\ units$

The perimeter of a rectangular garden is 43.8 feet. It’s length is 12.4 feet. What is it’s width?

Stells [14]

Answer:

9.5 m

Step-by-step explanation:

If width is -- x

12.4 + x + 12.4 + x = 43.8

2x = 19

x = (19/2)

x = 9.5 m

Thenks and mark me brainliest :))

Create an exponential to describe $100 at 2% interest, compounded annually, for x years. y=100(.98)^x y=100(.8)^x y=100(1.2)^x y

zysi [14]

The exponential to describe $100 at 2% interest, compounded annually, for x years is $y=100(1.02)^{x}$

<h3><u>Solution:</u></h3>

Given that $ 100 at 2 % interest , compounded annually for "x" years

<em><u>The formula for compound interest, including principal sum, is:</u></em>

$A=P\left(1+\frac{r}{n}\right)^{n t}$

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per unit t

t = the time the money is invested or borrowed for

Here in this sum,

P = $ 100

$r = 2 \% = \frac{2}{100} = 0.02$

number of years = x

Here given that compounded annually , so n = 1

Let "y" be the amount after "x" years

Substituting the values in formula we get,

$\begin{aligned}&y=100\left(1+\frac{0.02}{1}\right)^{1 \times x}\\\\&y=100(1+0.02)^{x}\\\\&y=100(1.02)^{x}\end{aligned}$

Thus the exponential to describe is $y=100(1.02)^{x}$

4.6 = 3.5w - 6.6 I need help please <3

marishachu [46]

Answer: w = 3.2

4.6 = 3.5w - 6.6

STEP 1: ADD 6.6 TO BOTH SIDES

4.6 = 3.5w - 6.6

STEP 2: DIVIDE 3.5 TO BOTH SIDES TO GET W

11.2 = 3.5w
