If the simple interest on ​$7000 for 3 years is ​$1890​, then what is the interest​ rate?

Answers

Answer:

0.09 or 9%

Step-by-step explanation:

I = Prt

Given:

I = 1890

P = 7000

t = 3

Work:

I = Prt

r = I/(Pt)

r = 1890/(7000 x 3)

r = 1890/21000

r = 0.09

A system of equations is shown on the graph below.


On a coordinate plane, 2 lines intersect at (negative 1, 2).

How many solutions does this system have?
no solutions
one unique solution
two solutions
an infinite number of solutions

Answers

Answer: One unique solution.

Step-by-step explanation:

When we have a system of linear equations like:

y = a*x + b

y = c*x + d

We have 3 possibilities:

1) There is only one solution, this happens when in the graph, the lines intersect at only one point.

2) There is no solution, in this case, the lines never intersect, this would be the case of two parallel lines.

3) We have an infinite number of solutions, this happens when both lines intersect in an infinite number of points, and this can only happen when both lines are the same line.

In this case, we know that we have two lines and they intersect in only one point, (-1, 2)

Then we have only one solution, and the solution is (-1, 2)

Answers

Answer:

Step-by-step explanation:

Answer:

slope=3, y-intercept=1

Step-by-step explanation:

slope is rise/run, so if you rise 3 and run 1 on the line, you get 4 for the slope, the y intercept is where the line crosses the y-axis, in this situation, it crosses it at (0,1).

Brooke went to the hardware store and bought 20 identical copper pipes. When Brooke lined up the pipes end-to-end, the line was 1 meter long. How long was each pipe?

Answers

Answer: 5cm

Step-by-step explanation:

First and foremost, we should note that

1 meter = 100 centimeters

Therefore, since Brooke went to the hardware store and bought 20 identical copper pipes and their total length is 1 meter long which is 100cm, the length of each pipe will be the title length of the Pipe divided by the number of pipes. This will be:

= 100 / 20

= 5cm each.

Each pipe is 5cm long.

STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.

Answers

Answer:

x = 12Side = 23 units

Step-by-step explanation:

STU is an equilateral triangle. And:

ST = 2x - 1SU = 5x - 37TU = x + 11

All sides are equal. Then take one pair and solve for x:

2x - 1 = 5x - 373x = 36x = 12

Substitute x to find the side length:

2x - 1 = 5x - 37 = x + 11 = 23
