A certain forest covers an area of 2100 km^2. Suppose that each year this area decreases by 5.25%. What will the area be after 6
Neko [114]

Answer:

The area after 6 years is 1519.49km^2

<em></em>

Step-by-step explanation:

Given

a = 2100 --- Initial Value

r = 5.25\% --- Rate

Required

Determine the area after 6 years

Because the area reduces,, the following formula will be used to solve the question.

y = a*(1 - r)^t

Here

t = 6

So, we have:

y = 2100*(1 - 5.25\%)^6

Convert percentage to decimal

y = 2100*(1 - 0.0525)^6

y = 2100*(0.9475)^6

y = 1519.47866516

y = 1519.49 -- approximated

<em>The area after 6 years is </em>1519.49km^2<em></em>

Idenify the numbers that are located below -3.5 on a vertical number line
belka [17]

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. The numbers that are located below -3.5 on a vertical number line are (-∞,-3.5).

<h3>What is a number line?</h3>

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

The numbers that are located below -3.5 on a vertical number line are all the numbers that are less than -3.5. The numbers that are located below -3.5 on a vertical number line are (-∞,-3.5).

I need help with 25 and 26 plzz
Paha777 [63]

Answer:

Step-by-step explanation:

25.

Combine like terms.

4t+7=-33

subtract 7 from both sides

4t=-40

divide both sides by 4

t=-10

26.

Subtract 2a from both sides

5=7a-16

add 16 to both sides

21=7a

divideby 7 on both sides

a = 3

I'd suggest getting the app photomath or using cymath to help you with these problems. they give you the answer and how to get it step by step
