Final answer:
Min will fill up 14 gallons of water if he runs his hose, which pumps 21 gallons per hour, for 2/3 of an hour.
Explanation:
If Min's hose can pump 21 gallons of water every hour, and he runs the hose for 2/3 of an hour, you would calculate the total gallons of water filled by multiplying the rate (21 gallons/hour) by the time (2/3 hour).
To find out how much water Min fills up:
Multiply the amount of water his hose pumps per hour by the fraction of the hour he runs it.21 gallons/hour × 2/3 hour = 14 gallons.Therefore, Min will fill up 14 gallons of water if he runs the hose for 2/3 of an hour.

Answer: 40°
Step-by-step explanation:
There are 4 pink angles (labeled as "a") and each are the same measure.
There are 4 green angles (labeled as "b") and each measure 50°.
A circle is 360°
4a + 4b = 360
4a + 4(50) = 360
4a + 200 = 360
4a = 160
a = 40

if x/8 =5/4 then x=10 true false
Answer:
true
Step-by-step explanation:
given
[tex]\frac{x}{8}[/tex] = [tex]\frac{5}{4}[/tex] ( cross- multiply )
4x = 40 ( divide both sides by 4)
x = 10
Final answer:
The equation x/8 = 5/4 is solved by multiplying both sides by 8, resulting in the correct solution x = 10. Thus, the statement is indeed true.
Explanation:
To solve the equation x/8 = 5/4, we need to perform algebraic operations to solve for x. We multiply both sides of the equation by 8 to isolate x on one side, which gives us:
x = (5/4) × 8
Now, we simplify this further:
x = (5 × 2) = 10
Therefore, the statement 'if x/8 = 5/4 then x = 10' is true, since we have confirmed that multiplying 5/4 by 8 indeed equals 10. It is important to understand that multiplication and division are inverse operations, and we can solve for an unknown by isolating it on one side of the equation.

A bike shop charges x dollars to rent a bike for half a day.it charges (x+40)dollars to rent for a full day.the table shows the shops bike rentals for one day.on that day the shop made a total of $600from bike rentals.how much does it cost to rent a bike for a full day?
The cost of full-day bike rental cannot be calculated because the information about how many half and full day rentals exist was not provided. This is needed to create an equation using the given variable and total revenue.
Explanation:
The question is about finding the cost of a full day bike rental. From the problem, we know that the total revenue from the rentals was $600. However, as the necessary information about the number of half-day and full-day rentals for the given day is not provided, we cannot provide a specific price. Usually, if we know the number of half-day and full-day rentals, we can set up an equation to determine the cost of a full day rental, denoted as (x+40) in the problem.

Solve for x: −3|x − 3| = −6
Answer:
x = 5 x = 1
Step-by-step explanation:
−3|x − 3| = −6
Divide each side by -3
−3/-3|x − 3| = −6/-3
|x − 3| = 2
An absolute value is equal to a positive and negative solution
x-3 =2 and x-3 = -2
Add 3 to each side
x-3+3 = 2+3 x-3+3 = -2+3
x = 5 x = 1

there are four students in each small reading group there are 24 students in all.
how many reading groups are there
Answer:
6
Step-by-step explanation:
24 / 4 = 6
Final answer:
The number of reading groups can be determined by dividing the total number of students, which is 24, by the number of students in each group, which is 4. The calculation is 24 ÷ 4, resulting in 6 reading groups.
Explanation:
To find the number of reading groups, we can use a simple division operation because we are dividing a larger group of items (students) into smaller equal-sized groups. In this case, we have 24 students and want to find out how many groups of 4 students we can create from that total.
Here's the step-by-step explanation:
Identify the total number of students, which is 24.
Identify the number of students in each reading group, which is 4.
Divide the total number of students by the number of students in each group: 24 ÷ 4 = 6.
Therefore, there are 6 reading groups.
Use the provided ruler suppose you re-create the drawing so I had a scale of 1 cm to 4 cm in length and width of the new scale drawing be
To recreate a drawing on a new scale of 1 cm to 4 cm, simply multiply the original dimensions by the scale factor of 4.
Explanation:If you are given a drawing and you want to recreate it on a new scale where 1 centimeter (cm) in the original equals to 4 centimeters in the new drawing, then you simply have to multiply the dimensions of the original by 4. Suppose the original drawing is 2 cm in length and 3 cm in width. Then the new length would be 2 cm * 4 = 8 cm and the new width would be 3 cm * 4 = 12 cm. Remember this is a general concept and can be applied to all dimensions of the drawing. It's a basic concept in proportion and scale factor.

Select the correct answer! Which point is the vertex of the graph defined by f(x) = 6|x − 2| − 5?
A. (6, 5)
B. (2, -5)
C. (0, 0)
D. (6, -2)
The Answer to your question is:
B: (2,-5)
Answer:
the vertex is (2,-5)
Step-by-step explanation:
f(x) = 6|x − 2| − 5
WE need to find out the vertex of the given absolute function
The vertex form of absolute function is
f(x) = a|x − h| +k
where (h,k) is the vertex
Now we compare the given f(x) with the vertex form
h= 2 and k = -5
so the vertex is (2,-5)
what is the height and length of a rectangular box with a volume of 6x^2-600 with a width of 6
Answer:
(x+10) and (x-10)
Step-by-step explanation:
The volume of a rectangular box is defined as
Volume = width*height*length
In this case
Volume = 6x^2-600 = 6*(x^2 - 100)
And we also know,
Volume = (6)*height*length
So,
6*(x^2 - 100) = (6)*height*length
This means that
height*length = (x^2 - 100)
height*length = (x+10)*(x-10)
