Write a sentence that describes the relationship between the dependent variable and the independent variable. (Hint: Ratio language can help.)
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
where y is the number of stokes,
x is the number of minutes
In the above relation, y is the dependent variable because its numerical value depends on time, while x is the independent variable.
Hence, The dependent and the independent variable in the relationship y=60x are y and x respectively.

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

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

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

Step-by-step explanation:
Divide by 100 to find this out. 108/100 = 1.08
You can remember this by knowing that the "centi-" prefix means 100 (technically, 100ths). Just like you probably already know 100 cents in a dollar (USD) or 100 years in a century. Even the "cent" in percent means per hundred. There are 100 centimeters in a meter. A centimeter is about as wide as your little finger. A meter is close to a yard.

find a number between 1 5/8 and 1.62501
Answer:
[tex]1 \frac{125001}{200000}[/tex] or 1.625005
Step-by-step explanation:
To find a number between two numbers, if you're allowed to pick any number you want between those two numbers, one natural choice is the midpoint... the point that is exactly halfway between the two numbers.
Finding a midpoint
To find the midpoint of two numbers, divide their sum by 2:
[tex]\text{midpoint}=\dfrac{\text{first number}+\text{second number}}{2}[/tex]
It is convenient to have both numbers in decimal form or both numbers in fraction form for adding and dividing by 2.
Fraction form:
To convert 1.62501 to a fraction, we note that the last decimal digit is in the hundred-thousandths place, so we'll need a fraction with 100,000 in the denominator.
[tex]1.62501=1\frac{62501}{100000}[/tex]
Using our midpoint formula:
[tex]\text{midpoint} = \dfrac{ 1 \frac{5}{8} + 1 \frac{62501}{100000} } {2}[/tex]
find a common denominator...
[tex]\text{midpoint} = \dfrac{ 1 +(\frac{5}{8})*\frac{12500}{12500} + 1 +\frac{62501}{100000} } {2}[/tex]
[tex]\text{midpoint} = \dfrac{ 1 + \frac{62500}{100000} + 1 +\frac{62501}{100000} } {2}[/tex]
combining like terms...
[tex]\text{midpoint} = \dfrac{ 2 +\frac{125001}{100000} } {2}[/tex]
rewriting the division as multiplication of a reciprocal....
[tex]\text{midpoint} = \left(2 +\frac{125001}{100000} \right) *\dfrac{1}{2}[/tex]
distributing...
[tex]\text{midpoint} = \left(2 *\dfrac{1}{2} +\frac{125001}{100000} *\dfrac{1}{2}\right)[/tex]
[tex]\text{midpoint} = 1 +\frac{125001}{200000}[/tex]
[tex]\text{midpoint} = 1 \frac{125001}{200000}[/tex]
So, [tex]1 \frac{125001}{200000}[/tex] is the midpoint of the two numbers, and is a number that is between them.
Decimal form:
To convert [tex]1 \frac{5}{8}[/tex] to a decimal, we divide 5 by 8. 5 divided by 8 is 0.625.
So, [tex]1 \frac{5}{8}=1.625[/tex]
To find a midpoint of 1.625 and 1.62501, we use our midpoint formula:
Using our midpoint formula:
[tex]\text{midpoint} = \dfrac{ 1.625 + 1.62501} {2}[/tex]
[tex]\text{midpoint} = \dfrac{ 3.25001} {2}[/tex]
[tex]\text{midpoint} =1.625005[/tex]
So, 1.625005 is midpoint of the two numbers, and is a number that is between them.
Extension with decimals:
Knowing the decimal form of the two numbers, 1.625 and 1.62501, we can include trailing zeros at the end of these numbers (since it is to the right of the decimal point), so that 1.625 is equivalent to 1.625000, and 1.62501 is equivalent to 1.625010.
Note that the last two digits are in the millionths place, and that changing the digit in the millionths place for the first number (while leaving all other digits as they are) will also be a number between the two numbers (all 9 of the numbers with a star written below):
1.625000

1) It's best to draw out a picture of a rectangle and label each corner with the coordinates given: Let's say (-5, 2) is point A, (-5, -2 1/3) is point B, (2 1/2, 2) is point C, and (2 1/2, -2 1/3) is point D.
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.
