If Camila filled up a 4-gallon in just 1/6 of a minute, then the rate of water flow through the hose is 24 gallons/minute
Camila filled up a 4-gallon bucket in just 1/6 of a minute
Here we have to use the unitary method to find the rate of water flow through the hose
The quantity of water filled in 1/6 of a minute= 4 gallon
The quantity water filled in one minutes = The quantity of water filled in 1/6 of a minute ÷ (1/6)
Substitute the values in the equation
= 4÷(1/6)
= 4×6
= 24
The rate of water flow through the hose = 24 gallons/ minute
Hence, if Camila filled up a 4-gallon in just 1/6 of a minute, then the rate of water flow through the hose is 24 gallons/ minute

Name the property used in the given expression −33/ 57 × −7/ 28 = −7/ 28 × −33/ 57 . With steps and solution pls
Step-by-step explanation:
as the other answer said, if is the commutative property of multiplication (the same as for addition, as multiplication is just a shortcut form of special additions) :
a × b = b × a
you need a solution ? you mean, you need this multiplication done and simplified, right ?
you know that
a/b × c/d = (a×c)/(b×d)
so,
-33/57 × -7/28 = -33/57 × -7/(4×7) =
= -33/57 × -1/4 = (-33×-1)/(57×4) =
= 33/228

When two parallel lines are intersected by a transversal 8 angles are formed.
Alternate exterior angles: These angles are located outside the parallel lines but on the opposite side of the transversal.
Alternate interior angles:
These angles are located inside the parallel lines but on the opposite side of the transversal.
Corresponding angles: These angles are located at the same relative position on the same side of the transversal.
b) A different pattern is made using 20 straight lines
and 14 arcs.
The straight lines and arcs are made from metal.
20 straight lines cost £12
cost of one straight line: cost of one arc = 2:3
Work out the total cost of metal in the pattern.
26.4
total cost of metal in the pattern is £24.6
What is ratio and proportion ?To compare two values is to use a ratio. A proportion is formed when two ratios have the same value. Choose whether the ratio is part-to-part or part-to-whole before you write it.
Calculation20 straight line cost £12
12 ÷ 20 = 0.6 per straight line
straight line : cost of one arc = 2:3
arc = 0.6 x (3/2) = 0.9
total = 12 + 14 x 0.9
= 12 + 12.6

Answer:
a. Perpendicular
Make sure to read the step-by-step explanation to figure out how to do the other 2.
Step-by-step explanation:
I will not be providing answers to all three, but I will answer the first one (this is, so you don't depend on people to solve this for you).
Parallel lines have one thing in common, their slope. Two lines that have the same slope never intersect because they are both facing the same direction and moving the same distance. So, you can find the slope of two lines by using the slope formula.
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m_1=\frac{-6-(-3)}{-4-2}=\frac{-3}{-6}=\frac{1}{2}\\m_2=\frac{-8-2}{2-(-3)}=\frac{-10}{5}=-2[/tex]
This is evidence that the two lines are not parallel. But, by finding the slope, we can conclude that it is perpendicular.
This brings me to how to identify perpendicular lines. The slope of perpendicular lines is negative reciprocals. A reciprocal is just a fraction that is flipped, and it's negative. For example, [tex]\frac{-2}{3}[/tex]'s negative reciprocal would be [tex]\frac{3}{2}[/tex]. The negative of -2/3 is a positive, and the reciprocal of 2/3 is 3/2. So, the negative reciprocal is 3/2.
How does this apply to what I said earlier?Well, [tex]-2[/tex] is the negative reciprocal of [tex]\frac{1}{2}[/tex]. The reciprocal of [tex]\frac{1}{2}[/tex] is 2, and the negative of 2 is -2. So, simply, lines 1 and 2 are perpendicular.
Use this method to solve the other questions. If they don't have the same slope and aren't negative reciprocals, then they are neither.
Answer:
Step-by-step explanation:
To solve this problem, we use the following formula:

Find the midpoint of each line segment
1) (4, 8)
2) (4, 8)
The midpoints are already given to you.
Answers:
(-1, 26) for problem 1(14, 12) for problem 2=======================================================
Explanation:
A = (9, -10)
B = (4,8)
C = (x,y)
A and C are the endpoints. B is the midpoint of segment AC.
The x coordinates of A and C are 9 and x respectively. Add them up and divide in half to get (9+x)/2. This is set equal to the x coordinate of point B and we solve for x.
(9+x)/2 = 4
9+x = 2*4
9+x = 8
x = 8-9
x = -1
The x coordinate of point C is -1.
Use the same idea for the y coordinates.
(-10+y)/2 = 8
-10+y = 2*8
-10+y = 16
y = 16+10
y = 26
Point C is located at (-1, 26)
The midpoint between (9, -10) and (-1, 26) is (4, 8)
Use the midpoint formula to confirm this.
------------------------
The steps for the second problem are going to follow the same outline.
A = (-6,4)
B = (4,8)
C = (x,y)
(-6+x)/2 = 4 solves to x = 14
(4+y)/2 = 8 solves to y = 12
Point C is located at (14, 12)
The midpoint between (-6, 4) and (14, 12) is (4, 8)

Kaj needs to order some new supplies for the restaurant where she works. The restaurant needs at least 736 knives. There are currently 155 knives. If each set on sale contains 12 knives, what is the minimum number of sets of knives Kaj should buy?
The minimum number of sets of knives Kaj should buy if the restaurant needs at least 736 knives is 48. 4 sets of knives
How to find the minimum number of sets of knives Kaj should buy?Number of knives needed by the restaurant = at least 736 knivesNumber of knives currently available at the restaurant = 155 knivesEach set of knives = 12Number of sets of knives needed to buy = x155 + 12x ≥ 736
substract 155 from both sides12x ≥ 736 - 155
12x ≥ 581

Answer:
The 5 students receive the larger amount.
100:5= 20 gram per student
100÷20= 5 gram per student
Step-by-step explanation:
prove me wrong
a shorter solution that probably will get full pts :
Because each group has the same mass of the chocolate bar, whichever group has less students will get a larger amount of chocolate per student (as there are less people receiving)
and here's if you think it is kinda not too detailed :
The first group has each student receiving 100 : 5 = 20 grams of chocolate per student
The second group has each student receiving 100 : 20 = 5 grams of chocolate per student
Both solutions give us a conclusion of : The group with 5 students have each of the receiving a larger amount of chocolate.

What is a slope?In mathematics, line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent the slope; reason for this usage is unclear, but it can be found in O'Brien's (1844) and Todhunter's (1888) formulations of equation for a straight line as "y = mx + b" and "y = mx + c," respectively.
He priced all items at a dime or a quarter. His sales totaled less than $5
Since dime =$ 0.10=$0.10 and the quarter =$0.25=$0.25
Let x=x= the number of the items sold for a dime
Let y=y= the number of the items sold for a quarter
0.10x+0.25y<5
0.10x+0.25y<5
Inequality in the slope-intercept form
0.10x+0.25y Subtract 0.10x from both sides
0.25y<-0.10x+5 Divide both sides by 0.25
Subtract 0.10x from both sides
[tex]y= -\frac{2}{5}x+20\\[/tex]
The slope is, [tex]-\frac{2}{5}[/tex] and the y- intercept is 20
Since inequality sign is << so, draw a dashed line
Test point (0,0)(0,0)
Substituting the values 0 for x and 0 for y,
[tex]y < -\frac{2}{5}x+20\\\\0 < -\frac{2}{5}(0)+20\\\\0 < +20[/tex]
Since inequality is true
So, (0,0)(0,0) is solution of the inequality
