The amount spent on promotion by the store on monthly sales of $86,600, when they are spending 14 percent on promotion is $12,124.
The percent signifies the hundredth part of the whole.
When informed that the promotion is 14 percent of the monthly sales of $86,600.
Therefore, to calculate the total amount spent on promotion, we calculate 14 percent of 86600.
Therefore, the total amount on promotion = 14% of $86,600 = $ (14/100 * 86,000) = $ (14*866) = $12,124.
Therefore, the amount spent on promotion by the store on monthly sales of $86,600, when they are spending 14 percent on promotion is $12,124.

Theodore invests a total of $11,000 in two accounts paying 8% and 4% annual interest, respectively. How much was invested in each account if, after one year, the total interest was $780.00.
________ was invested at 8% and
______ was invested at 4%.
The amount loaned at the interest rate of 8% is $2,500.
The amount loaned at the interest rate of 4% is $8,500.
What are the linear equations that represent the question?a + b = 11,000 equation 1
0.08a + 0.04b = 780 equation 2
Where:
a = amount loaned at the interest rate of 8%b = = amount loaned at the interest rate of 4%How much was loaned at 8% and 4%?In order to determine how much was loaned at 4%, take the following steps:
Multiply equation 1 by 0.08
0.08a + 0.08b = 880 equation 3
Subtract equation 2 from equation 3:
0.04b = 100
Divide both sides by 0.04:
b = $2500
Subtract 2,500 from 11,000 :
11,000 - 2,500 = $8,500

Describe the transformations to the graph of y = x² to obtain y = -2 ( x + 5 )²- 3 .
Using translation concepts, the transformations are given as follows:
Reflection over the x-axis.Vertical stretch by a factor of 2.Shift left of 5 units.Shift down by 3 units.What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The parent function is given by:
y = x².
The translated function is:
y = -2(x + 5)² - 3.
In this problem, we have that:
The function was multiplied by -2, hence it was reflected over the x-axis, as it was multiplied by a negative value, and vertically stretched by a factor of 2.x -> x + 5, hence the function was shifted left 5 units.y -> y - 3, hence the function was shifted down 3 units.More can be learned about translation concepts at https://brainly.com/question/4521517

Sentence : "I did 60 brush strokes in 1 minute"
The dependent and the independent variable in the relationship y=60x are y and x respectively.
The Independent variables are variables whose value does not depend on any other variable. And it causes the change in other variables.
The dependent variable is those variables whose value is not independent and change in this variable is dependent on the change of the independent variable.
Given that you did 60 brush strokes in 1 minute. Therefore, the rate can be written as,
Rate = 60 strokes per minute
Now, the number of stokes in x minutes can be written as,
y = 60x

2) That being said, line AB is one side of the rectangle, BC is another, CD is another, and lastly, AD is the fourth side.
3) We can use the distance formula and plug in the coordinates of each line to find how long every side is. Then you just need to solve it.
For example: if I want to find how long side AB is, I would use the point A (-5, 2) and B (2 1/2, 2) and plug them into the distance formula, where (-5, 2) is (x1, x2) and (2 1/2, 2) is (x2, y2) and solve that.
4) Repeat this process with side BC, CD, and AD, and add the results together. This will be your final answer; the perimeter of the rectangle.

What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
There are 32 students in the orchestra and twice that number in the band. Therefore the number of students in the band is:
Number of students in band = 2 (Number of students in Orchestra)
= 2 × 32 = 64
The number of students in the Choir is the sum of the number of boys and girls. Therefore, the number of students in the Choir is,
Number of students in the Choir = 19 + 11 = 30
Total number of students = 32 + 64 + 30 = 126

An angle measures 87.6° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
1.2° and 88.8°Step-by-step explanation:
Complementary angles are angles that add up to 90°.
Let's say angle 1 is x, and angle 2 is 87.6 less than x.
We already know that angle 1 + angle 2 = 90, so we can just substitute x now.
We know that complementary angles add up to 90, so one of the angles is 90-x, and the other one is 90-x-87.6.
x = (90 - x) - 87.6
Simplifies to:
x = 2.4-x
Add x to both sides
2x = 2.4
Divide by 2
x = 1.2
To get the other angle, add 87.6 to 1.2
1.2+87.6 = 88.8
So, angle1 = 1.2, and angle2 = 88.8
Let's check our work.
88.8 + 1.2 = 90, so the angles are complementary and have a difference of 87.6
Hope this helps (:
Answer:
1.2°, 88.8°
Step-by-step explanation:
let one angle=x
other angle=y
y=x-87.6
also
x+y=90
x+x-87.6=90
2x=90+87.6=177.6
x=88.8

Find the equation of the line.
Through (-11, -1); perpendicular to y=15.
Answer:
x = - 11
Step-by-step explanation:
y = 15 is a horizontal line parallel to the x- axis
a perpendicular line must therefore be a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
the line passes through (- 11, - 1 ) with x- coordinate of - 11 , then
x = - 11 ← equation of perpendicular line
Answer:
x = -11
Step-by-step explanation:
The line y = 15 is a horizontal line to the x-axis passing which passes through x = 0, y = 15
The line perpendicular to y = 15 passing through (-11, -1) is a vertical line where x = -11 for all values of y including -1
So the equation is x = -11
