Answer:
2 cents per can
Step-by-step explanation:
The price per can when you buy two cans is:
0.33/2 = $0.165, or 16.5 cents per can
When purchased in a lot of one dozen, the price per can is:
1.74/12 = $0.145, or 14.5 cents per can
So the savings per can when you buy a dozen is:
0.165 - 0.145 = $0.02, or 2 cents per can
Answer:
You save 2 cents per can. $0.02
Step-by-step explanation:
Since one dozen = 12, you need to figure out what 12 can would regularly cost. So multiply the 33 cents by 6 (since 2 x 6 =12).
33 x 6 = 198
Add the decimal and it's $1.98. now subtract $1.74 from $1.98.
1.98 - 1.74 = 0.24
This is the saving for 12 cans, but you want the savings for one can. So you would divide 0.24 by 12.
0.24/12 = 0.02
So you save 2 cents per can.

how do i do this and what’s the answer????
Answer:
The correct answer is z = -6.
Step-by-step explanation:
1/3 (2z + 6) = 1/4 (z - 2)
The first step I am going to take is to multiply both sides of the equation by 12 (the least common multiple of 3 and 4). This will eliminate the fractions on both sides of the equations and make the numbers much easier to work with.
4 (2z + 6) = 3 (z - 2)
Next, we can use the distributive property to eliminate the parentheses. This means multiplying each term inside the parentheses by the coefficient on the outside of the parentheses.
8z + 24 = 3z - 6
Now, we can subtract 3z from both sides of the equation.
5z + 24 = - 6
Next, we should subtract 24 from both sides of the equation.
5z = -30
Finally, we can divide both sides of the equation by 5.
z = -6
Therefore, the correct answer is z = -6.
Hope this helps!

This diagram is a straightedge and compass construction. A is the center
of one circle,
and B is the center of the other. Explain how we know triangle ABC is
equilateral.
Answer/Step-by-step explanation:
Segments AB and AC are both radii of the circle with center A. All radii of a circle are always equal, tgerefire,:
[tex] AB = AC [/tex]
Segments AB and BC are both radii of the circle with center B. All radii of a circle are always equal, therefore:
[tex] AB = BC [/tex]
Thus,
[tex] AB = AC = BC [/tex]
∆ABC has sides AB, AC, and BC, which are all equal (equal radii).
Therefore, ∆ABC is an equilateral triangle.
An equilateral triangle has 3 equal sides.

A pool contains 50 gallons of water and is filling at a rate of 2.3 gallons per minute. A second pool contains 102.2 gallons of water and is draining at a rate of 3.5 gallons per minute. After how many minutes will the pools contain the same amount of water?
At time t, the first pool contains 50+2.3t gal of water, while the second pool contains 102.2-3.5t gal.
They contain the same amount of water when these quantities are equal:
50 + 2.3t = 102.2 - 3.5t
5.8t = 52.2
t = 9
so the pools have the same amount of water after 9 min have passed.
The pools will contain same amount of water in 9 minutes
Let the number of minutes that the pools contain the same amount of water be represented by t.
Since the first pool contains 50 gallons of water and is filling at a rate of 2.3 gallons per minute, then this will be:
= 50 + (2.3 × t)
= 50 + 2.3t ......... equation i
The second pool contains 102.2 gallons of water and is draining at a rate of 3.5 gallons per minute. This will be:
= 102.2 - (3.5 × t)
= 102.2 - 3.5t ........ equation ii
Equate both equations and this will be:
50 + 2.3t = 102.2 - 3.5t
Collect like terms
2.3t + 3.5t = 102.2 - 50
5.8t = 52.2
Divide both side by 5.8
5.8t/5.8 = 52.2/5.8
t = 9
In conclusion, they'll have same amount of water in 9 minutes

What is the solution to this system of equations?
x + y = 6
x = y + 4
A: (11/2, 1/2)
B: (21/2, 11/2)
C: (5, 1)
D: (1, 5)
Answer:
(5, 1) (Answer C)
Step-by-step explanation:
Note that the second equation features x as a function of y: x = y + 4. We can substitute y + 4 for x in the first equation, obtaining:
y + 4 + y = 6
and then, after we combine like terms,
2y = 2, or y = 1.
x = y + 4, subbing 1 for y here results in x = 1 + 4, or x = 5
The solution is (5, 1) (Answer C)

Step-by-step explanation:
hope this helps, I did OSM 202 MC , as well.
The TREATMENT sum of squares measures the variability of the sample treatment means around the overall mean.
The sum of squares is used to measure the variation about the mean, In ANOVA we have:
• Sum of square Error : measures the variation between each observation in a group and the mean of that group.
• Sum of square treatment : measures the variation between the mean of each group and the overall mean.
• Total Sum of Square : measures the variation between each observation and the overall sample mean.
Hence, Treatment sum of squares measures variation between sample treatment and overall sample mean.

Which of the following correctly classifies the number -5 to all of the number sets in which it belongs?
=============================================
Explanation:
Any number you'll encounter so far in your math course will be a real number. This is until you get to something like [tex]\sqrt{-1}[/tex] which is a complex number, but your teacher may not have covered that chapter yet.
Anyways, -5 is a real number because we aren't taking the square root of a negative or anything like that.
-5 is also an integer, but that choice isn't listed. The set of integers is any positive or negative whole numbers, including 0 as well.
Furthermore, -5 is considered rational because -5 = -5/1. We can write -5 as a fraction of two integers where 0 is not in the denominator. With -5 being rational, it cannot be irrational. The term "irrational" means "not rational".
For the transformation T, write the T-1. T: (x, y) ( 2x, y + 5) T -1 (x, y) (x - 2, y - 5) (2x - 1, y + 4) (½x, y - 5)
=====================================
Explanation:
The original transformation (2x, y+5) takes any x value and doubles it. So the inverse of this is to cut the x value in half. We can say x/2 since division is the opposite of multiplication. The value x/2 is the same as ½x
For the y coordinate, we add on 5 for the original transformation. Subtraction undoes addition meaning the inverse will have y-5.
Side note: the inverse notation [tex]T^{-1}[/tex] can be written as T^(-1).

Work out the angle marked x in each diagram you must show your working
Anwser: 41°
Okay so every triangle is 180° degrees in total.
We need to find the angle of x in the triangle BDC.
We know that the angle of x is 180 - ( x + 15)
We also have another triangle named BAD
Which angles are 90 + 56 + x
the angle of D in the triangle BDC is 180 -58 = 124
So 124 + 15 = 139
180 - 139 = 41

AB is parallel to CD, and EP is perpendicular to AB.
The number of 90° angles formed by the intersections of EP and the two parallel lines AB and CD is
Answer:
8 right angles
Step-by-step explanation:
1. If two lines are perpendicular then we know they form 4 right angles, so EP and AB from 4 right angles.
2. The question states that AB and CD are parallel. Since we know EP is intersecting AB and CD, we can say that EP is perpendicular to CD as well because of a theorem that states, "...that if there are two parallel lines in the same plane and there is a line perpendicular to one of them, then it is also perpendicular to the other one."
3. So because of that theroem, we can add another 4 right angles from the intersection of EP and CD.
4. When you add all the right angles together, you get 8 right angles in total.

Find the inverse of the function. f(x) = 5x + 6 A). f-1(x) = quantity x plus six divided by five B). Not a one-to-one function C). f-1(x) = x divided by five minus six D). f-1(x) = quantity x minus six divided by five
Answer:
D
Step-by-step explanation:
To find the inverse, all we have to do is switch the x and f(x) so instead of f(x) = 5x + 6, it becomes:
x = 5f(x) + 6
x - 6 = 5f(x)
f⁻¹(x) = (x - 6) / 5
