1 hour
Step-by-step explanation:To solve this problem, we will need to use the unitary method.
Determining the equation:
⇒ 55 deliveries in 11 hours
⇒ 55 deliveries = 11 hours
Finding how much hours in 5 deliveries:
Divide both sides by x:
⇒ 55 deliveries = 11 hours
⇒ 55/x deliveries = 11/x hours
Simplify the numerators:
⇒ 55/x deliveries = 11/x hours
⇒ 5/x deliveries = 1/x hours
Use cross multiplication:
⇒ 5x deliveries = x hours
Divide both sides by x:
⇒ 5x/x deliveries = x/x hours
⇒ 5 deliveries = 1 hour
Answer:
1 hour
Step-by-step explanation:
let x = unknown number of hours
Set up ratios of deliveries to hours
[tex]\sf \implies 55 : 11 = 5 : x[/tex]
[tex]\sf \implies \dfrac{55}{11}=\dfrac{5}{x}[/tex]
Cross multiply:
[tex]\sf \implies 55x=5 \cdot 11[/tex]
[tex]\sf \implies 55x=55[/tex]
Divide both sides by 55:
[tex]\sf \implies x=1[/tex]
Therefore, 55 deliveries in 11 hours = 5 deliveries in 1 hour

Classify each equation as defining y as a linear or nonlinear function of x. Select one cell per column.
Answer:
1. nonlinear
2. nonlinear
3. nonlinear
4. linear
5. linear
6. nonlinear
I think that is correct
Step-by-step explanation:
There is two ways you can do it.
1st . See if it is being multiplied, x cannot be the denominator, y cannot have a exponent and the x cannot be squared.
2nd - Use a graphing calculator and see if the line is straight, that is a linear equation and curved lines are nonlinear.

What is the length of one side of a square when it has an area of 100 inches squared?
and what is the squares perimeter?
Answer:
L = 10 in
P = 40 in
Step-by-step explanation:
The area of a square is given by the equation:
A = L²
We rearrange this equation to make L the subject:
Square root both sides:
√A = L
Now we substitute A into our rearranged equation to find L:
L = √A
L = √100
L = 10 in
The perimeter of a square is given by the equation:
P = 4L
Substitute the L we just found to find P:
P = 4(10)
P = 40 in
help me do examples for a function and a non function
Answer:
{(1,2) (3,4) (5,6)} and {(1,2) (1,4) (5,6)}
Step-by-step explanation:
you really want to think of a function as a vending machine. if you press B12 on a vending machine because thats where the chips are, only the chips should come out. in a function, the input value aka x (B12, what youre putting in) should only have one output value aka y, (the chips)
an example of a function would be {(1,2) (3,4) (5,6)}
an important thing to remember is that one output value can belong to multiple input values. there can be chips (output) in both B12 and C12 (inputs) BUT as i said before, there CANNOT be two outputs for one input. B12 cannot give you both chips and a drink.
using this, another example of a function would be {(1,2) (3,2) (5,2)}
an example of an non function would be {(1,2) (1,4) (5,6)} because x, the input value, has multiple output values which is not possible. the output of 1 can not be 2 and 4 at the same time which we can see in the (x,y) coordinates.

A muffin requires 1/8 a cup of sugar for 1/2 a batch. How many cups of sugar do you need to make 1 batch?
Answer:
1/4 or 2/8
Step-by-step explanation:
2/8 because you need to multiply by 2 witch 1/8 x 2 = 2/8 which is equal to 1/4
Answer:
1/4
Step-by-step explanation:
if 1/2 a cup requires an eighth of the sugar one batch will require two eighths, which is a quarter :1/8+1/8=2/8 which is 1/4
The equation y=34.99x represents the total amount of money (y) that the Geocove waterpark will collect if they charge $34.99 per adult (x) for admission to their waterpark.
Name the y-intercept of this line and interpret what it means in the context of admission to the waterpark.
Answer:
The y-intercept is where the line crosses the y-axis on the graph also where x=0. In this situation the y-value is however much money the waterpark will make depending on how many adult tickets sold.

Answer:
Range = 7
Mean = 7.75
Assumption: Most students will have 7 or 10 letters in their last name
Step-by-step explanation:
Range = Largest - Smallest
= 10 - 3
= 7
Mean = Add the total numbers up to get a total / numbers in the series
= (3+5+2(6)+2(9)+5(7)+4(8)+5(10)) / (1+1+2+5+4+2+5)
= 7.75
Triangle PRQ was transformed to create triangle P'R'Q'. if point P started at coordinates (6,-54), and became point P' at coordinates (-6,-54), describe the transformation that was applied to triangle PRQ.
Answer:
PRQ was translated 90 degrees clockwise.
If (6,-54) is located in q4 (+,-) and rotated to land on (-6,-54) which is in q3 then it was rotated 90 degrees clockwise.

A small theater had 9 rows of 25 chairs each. Workers just removed 6 of these chairs. How many chairs are left?
9 * 25 = 225
225 - 6 = 219
There are 219 chairs left.
Answer:
219 Chairs are left.
Step-by-step explanation:
[tex]\rightarrow[/tex] Each row has 25 chairs. And there are total 9 rows.
So, total number of chairs = 25×9
= 225
➾ Workers removed 6 chairs, so left number of chairs = 225-6
= 219 chairs.

answer for brainliest
Step-by-step explanation:
diameterfor first minute :
Circumference = 25.12
2πr = 25.12
22/7 × r = 25.12/2
r = 12.56 × 7 /22
r = 87.92/22
r = 3.99 mm ( approx. )
diameter = 2r = 2 × 3.99 = 7.98 mm
diameter for second minute =
circumference = 75.63
2πr = 75.63
πr = 75.63/2
r = 37.815 × 7/22
r = 264.705/22
r = 12.032 mm
diameter = 2r = 24.064 mm
COMPARISON : 24.064/7.98

Ellen draws a square on a coordinate plane. One vertex is located at (5, 5). The length of each side is 3 units. Which of the following ordered pairs could be another vertex?
Group of answer choices
(1, 8)
(8, 5)
(2, 4)
(7, 5)
Answer:
(8, 5)
Step-by-step explanation
By adding or subtracting three to either the x or why coordinate of the given point, you can achieve any of the four vertexes of the square.
The black line represents your equation from Question 7. Compare the black and blue lines.
Include in your answer:
*Slope-intercept form (y=mx + b) of the blue line. Show or explain your work.
*Which line has the greater slope? How do you know?
Hint: Find the y-intercept. Then count up and over (y/x) to the next point on the line to determine the slope.
Answer:
The black line has the greater slope.
Step-by-step explanation:
One way to think about which line has the greater slope is to imagine (or draw) a car on top of each line driving from left to right. If the car is driving up a steeper hill then the slope is greater.
To show your work though, starting at the y-intercept on the black line, find another point that you can see well on the line such as (3, 4). To get from the y-intercept to (3,4) go up 2 and right 3 so the slope is 2/3.
For the blue line, find a point that is easy to see such as (2, 3). To get from the y-intercept to (2, 3) go up 1 and right 2 so the slope is 1/2.
(Remember slope is y/x or rise/run)
Since 2/3 is bigger than 1/2, the slope of the black line is greater.
