Answers

Answer 1

Answer:

Depreciation formula:

Total = starting value x (1 - percentage)^time

Total = 4200 x (1-0.08)^15

Total = 4200 x 0.92^15

Total = 1202.449 km^2

Rounded to nearest km = 1202 km^2

Can someone show me how to graph this?

Answers

Answer:

Step-by-step explanation:

Hello,

This is the equation of a line so if you know two points of the line you can graph it, right?

For x = 0 y = -3 so the point A (0,-3) is on the graph

For x = 3 y =-4 so the point B (3,-4) is on the graph

And then you can draw the line as below

Thanks

Use Euler's formula to find the missing number vertices 22
edges 34
faces?
a.10
b.12
c.14
d.16

Answers

Euler's formula is given by:
C + V = A + 2
Where,
C = Number of faces
V = Number of vertices
A = Number of edges
Substituting values we have:
C + 22 = 34 + 2
Clearing C we have:
C = 34 + 2-22
C = 14
Answer:
c.14

How to solve -2x-10x12=18

Answers

Answer:

x = −69

Step-by-step explanation:

1: Simplify

−2x−(10)(12)=18

−2x+−120=18

−2x−120=18

2: Add 120 to both sides.

−2x−120+120=18+120

−2x = 138

3: Divide both sides by -2.

-2x ÷ -2 = 138 ÷ -2

x = −69

Answer:

x=-69

The distance between -6 and 15 on a number line is 9?

Answers

The distance between -6 and 15 on a number line is 21.

What is number line?

A straight line with numbers placed at equal intervals or segments along its length. Number line is a straight line with a "zero" point in the middle, with positive and negative numbers listed on either side of zero and going on indefinitely.

Given:

The distance between -6 and 15 on a number line is 9 is true or false.

We have to find the the distance between -6 and 15 on a number line.

According to given question we have

15 - (- 6)

= 15 + 6

= 21

The distance between -6 and 15 on a number line is 9 is false.

Therefore, the distance between -6 and 15 on a number line is 21.
