Total time taken by Andrew and bob is 2hr.
given, time taken by Andrew to paint the room = 3hrtime taken by bob to paint the room =6hr rate of Andrew as x =1/3.
rate of bob as y=1/6x+y=1/3+1/6=1/2
total time taken by Andrew and bob =1/x + y
=1/1/3+1/6
= 2hr.
therefore total time taken by Andrew and bob is 2 hr.
The formula for time is given as [Time = Distance ÷ Speed]. To calculate the distance, the time formula can be molded as [Distance = Speed × Time].
To get the total decimal hours we use the formula: h = hours + (minutes / 60) + (seconds / 3600). To get the total decimal minutes we use the formula: m = (hours * 60) + minutes + (seconds / 60).
The types of functions can be broadly classified into four types. Based on Element: One to one Function, many to one function, onto function, one to one and onto function, into function.

Have an amazing day!
a box has dimensions of 3.5 cm by 4.0 cm by 8.0 cm. the volume of the box in milliliters and liters is:
Step-by-step explanation:
3.5cm===> 35mm===> 3.5e–6 lit
4.0cm===> 40mm===> 4.0e–6 lit
8.0cm===> 80mm===> 8.0e–6 lit
V(mm)=35×40×80=112000mm³
V(lit)=(3.5×4.0×8.0)×e–6=112e–6lit³
Solve: 10+5(x-4) = 35
Answer:
x=9
Step-by-step explanation:
10+5(x−4)=35 Step 1: Simplify both sides of the equation. 10+5(x−4)=35
10+(5)(x)+(5)(−4)=35(Distribute)
10+5x+−20=35
(5x)+(10+−20)=35(Combine Like Terms)
5x+−10=35
5x−10=35
Step 2: Add 10 to both sides.
5x−10+10=35+10
5x=45
Step 3: Divide both sides by 5.
5x/5 = 45/5
x=9
Answer:
x=13
Step-by-step explanation:
10+5(x-4)=35
10+5x+-20=35
5x+-30=35
5x=65
65 divided by 5=13
x=13

The rectangle shown has a perimeter of 54 cm and the given area. Its length is 3 more than twice its width. Write and solve a system of equations to find the dimensions of the rectangle. The length of the rectangle is _ cm and the width of the rectangle is _ cm.
Answer:
length of the rectangle is 19 cm and the width of the rectangle is 8 cm.
Step-by-step explanation:
The formula for the perimeter of a rectangle = 2L + 2 W
Where:
L = length and W = width
The rectangle shown has a perimeter of 54 cm
Its length is 3 more than twice its width.
2L + 2W = 54 .... Equation 1
"length is 3 more than twice its width."
L = 2W + 3.....Equation 2
Substituting 2W + 3 for L
We have:
2L + 2W = 54 .... Equation 1
2(2W + 3) + 2W = 54
4W + 6 + 2W = 54
6W = 54 - 6
6W = 48
W = 48/6
W = 8cm
L = 2W + 3.....Equation 2
L = 2(8) + 3
L = 16 + 3
L = 19 cm
Therefore:
length of the rectangle is 19 cm and the width of the rectangle is 8 cm.

A. The y intercept the y coordinate when the line passes through the point that is on the y coordinate and the x is 0. In this context, the y intercept is 10.
B. The slope is the number of units the line goes up every number of units it goes to the right. This line goes up 50 every 20 units to the right so the slope is 50/20 which simplifies to 5/2
C. The equation is y = 5/2x + 10

The main purpose of EFA is to find out the relationship between variables.
EFA is an abbreviation for exploratory factor analysis, which is used to determine the link between variables that are assessed.Exploratory factor analysis is a statistical tool used in multivariate statistics to find the underlying structure of a rather large set of variables. EFA is a factor analysis approach with the overriding purpose of identifying the underlying connections between measured variables.The common factor concept underpins EFA. Manifest variables are expressed as a function of common components, unique factors, and measurement errors in this model. Each distinct component has an effect on only one manifest variable and does not explain relationships between manifest variables. Common factors impact several manifest variables, and "factor loadings" are measurements of a common factor's influence on a manifest variable.To learn more about statistics, visit :

Use the area of the rectangle to find the area of the triangle.
4 ft
8 Ft
Answer:
The area of the triangle is 16 feet because the are of the rectangle is 32 feet.
Step-by-step explanation:
The length of the rectangle is 8 feet. Since the dotted line is exactly in the middle of the rectangle, the bottom of the triangle s 4 feet. With 4 feet as the bottom and 4 as the height, we can calculate the area of one of the triangles ( 4 * 4 /2 ), so each of the triangle's area is 8 feet. Add them together, and you get 16!

She writes the sum of the ten integers, then factors her expression.
She correctly determines the total change for the 10 months.
What factored expression does she write, and what is her answer?
Answer:
-14
Step-by-step explanation:
Find out how many times (-11) , (-1) and 17 appears.
(-11) is four times and (-1) is four time.
4 * (-1) + 4 * (-11) = 4 * (-1 - 11)
17 is appearing two times.
2*17
Now, the expression is,
4 * (-1 - 11) + 2 *17
4 * (-1 - 11) + 2 *17 = 4 *(-12) + 34
= - 48 + 34
= -14
How many fluid ounces are in a gallon?
1 cup= 8 ounces
1 pint= 2 cups
1 quart=2pints
1 gallon= 4 quarts
Answer:
128 fluid ounces
Step-by-step explanation:
As per linear equation, there are 128 ounces of fluid in a gallon.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."
Given relations for any fluid is:
1 cup = 8 ounces
1 pint = 2 cups
1 quart = 2pints
1 gallon = 4 quarts
Therefore,
1 gallon
= 4 quarts
= 4 (2) pints
= 8 pints
= 8(2) cups
= 16 cups
= 16(8) ounces
= 128 ounces
Therefore, for any particular fluid 128 ounces equal to 1 gallon.

Leo wants to buy some shoes. He found the shoes at three different stores for a spice of $35. The stores are each having a sale. Which statement about the sale price of the shoes is true
Answer: Store Z has the best sale price of $28.
Step-by-step explanation:
Here is the complete question:
Leo wants to buy some shoes. He found the shoes at three different stores for a price of $35. The stores are each having a sale.
Store X is offering 15% off the price of the shoes.
Store Y is offering $5 off the price of the shoes.
Store Z is offering a discount 1/5 off the price of the shoes.
Which statement about the sale price of these shoes is true?
a. Store X has the best sale price of $20.
b. Store Z has the best sale price of $28.
c. Store Y has the best sale price of $30.
d. Store Z has the best sale price of $7.
Since Store X is offering 15% off the price of the shoes, the price of the shoe at store X will be:
= $35 - (15% × $35)
= $35 - (0.15 × $35)
= $35 - $5.25
= $29.75
Since Store Y is offering $5 off the price of the shoes, the price of the shoe at store Y will be:
= $35 - $5
= $30
Since Store Z is offering a discount off the price of the shoes, the price of the shoe at store Z will be:
= $35 - (1/5 × $35)
= $35 - $7
= $28
Base on the analysis above, Store Z has the best sale price of $28.

15. Scarlett estimated that there were 50 pieces of candy left in her Halloween basket. When she counted,
there was actually only 46 pieces left. What was her percent error?
Answer: 8% Error
Step-by-step explanation:
Lets go ahead and change the equation to a format that we're more familiar with.
Original:
50 -> 46
But what's easier is if we are working with 100's because of 100% right?
So lets do this.
100 -> 92
All I did was multiply both by 2 to get 100 to 92. Now it's easier to determine because of what we're looking at. 100-92 is 8% which also makes 50 to 46 an 8% error because of the symmetry between both equations. Enjoy!
