For Simple Interest, I = PRT/100

Time = 1 year.

I = P*R*1/100

100*I =  PR

100I / P = R

The formula for the Rate, R = 100I / P.

Answer:

Angle measure KRQ is 146 degrees

Step-by-step explanation:

Here, we want to find the measure of the indicated angle

From what we have in the question;

angle measure KRQ is corresponding to angle measure KNM

Mathematically, when two angles are corresponding to each other, their values are equal

What this means is that the value of the measure of KRQ is 146 degrees too

Write the equation of a line that is parallel to y= 3x-2 and that passes through (9,-5).
sergij07 [2.7K]

Answer:

y = -1/3x + 2

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals.

The line y = 3x - 2 has slope 3.

The perpendicular line has slope -1/3.

Now we find the equation of the line that has slope -1/3 and passes through (-9, 5).

y = mx + b

y = -1/3x + b

5 = (-1/3)(-9) + b

5 = 3 + b

b = 2

The equation of the perpendicular is

y = -1/3x + 2

Suppose that you need to build as many chairs as possible. Each chair requires one seat, one back, and four legs. If you have 12
GrogVix [38]

Answer:

  legs limit the number of chairs that can be built

Step-by-step explanation:

The maximum number of chairs that can be built will be the minimum of the number of parts divided by the number of parts needed for each chair, as computed across the different kinds of parts required.

  seats: 12 available, used 1 per chair: 12/1 = 12 chairs possible

  backs: 15 available, used 1 per chair: 15/1 = 15 chairs possible

  legs: 44 available, used 4 per chair: 44/4 = 11 chairs possible

The maximum number of chairs that can be built will be the minimum of 12, 15, and 11. That is, 11 chairs can be built, limited by the number of available legs.
