Am cla ha collected 52 can in a food drive. They plan to ort the can into a x bag, with an equal number of can in each bag. Write an expreion to how how many can there will be in each bag
Answer:
Math Expert Answer
Step-by-step explanation:
52 cans in total separated into x number of bags. 52/x with x being the number of bags.
Answer:
c = 52/x
Step-by-step explanation:
We have 52 total cans and x bags of with an equal amount of cans in each.
Thus, we would have c = 52/x cans per bag. This is probably the answer you are looking for.
However, this can evaluate to a fractional number of cans, so you may be looking to round that answer down to an integer. In that case, the answer would be c = ⌊52/x⌋, which is solving for the greatest integer less than the value of 52/x

1/2(3x-2/3)+6 less or equal to x+5
The inequality which represents the given phrase is 1/2(3x - 2/3) + 6 ≤ x+5 and the solution are x ≤ -4/3.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given,
1/2(3x - 2/3) + 6 ≤ x+5
3/2 x - 1/3 + 6 ≤ x+5

The midpoint of AB is M(3,-3). If the coordinates of A are (2, -1), what are the
coordinates of B?
Answer:
The coordinates of B is (4, 7)
Step-by-step explanation:
To find the answer for B, you have to do the inverse of the midpoint formula, which is M equals (x1 multiplied by x2, over 2; y1 multiplied by y2, over 2).
If you substitute in A's coordinates for x1 and y1, you come up with (3, 3) = (2+x, over 2; and -1+y, over 2)
If the x coordinate answer for AB was 3, you can create an equation like this to solve for B's x coordinate: 2+x over 2 equals 3.
you multiply 2 by 3 to get 6---> 2+x=6-----> x=4
If the y coordinate for AB was also three, you can create another equation to solve for B's y coordinate: -1+y over 2 equals 3.
you multiply 2 by 3 to get 6 again---->so -1+y=6---->y=7
so the answer for B's coordinates is (4, 7).
Answer:
B(4, - 5)--------------------------
Given:
A = (2, - 1), Midpoint M = (3, - 3),Find the coordinates of the other end point B.
Use midpoint equation, considering point B as (x, y):
3 = (2 + x)/2 ⇒ 2 + x = 2*3 ⇒ 2 + x = 6 ⇒ x = 4,- 3 = (- 1 + y)/2 ⇒ -1 + y = 2*(-3) ⇒ -1 + y = - 6 ⇒ y = - 5.Therefore the point B has coordinates of (4, - 5).

Find the equation of the line, given the following information:
Passes through (-9,3) and is perpendicular to
y=1/2x+6
Answer:
y=2/5x + 33/5
Step-by-step explanation:
To find the equation of the line that passes through the point (-9,3) and is perpendicular to y = 1/2x + 6, we can first find the slope of the given line y = 1/2x + 6. The slope of a line is equal to the rise (the change in the y-coordinate) divided by the run (the change in the x-coordinate), so we can find the slope of the line y = 1/2x + 6 as follows:
Slope = (change in y) / (change in x)
= (1/2 - 6) / (1 - 0)
= -5/2
Since the line we are looking for is perpendicular to the line y = 1/2x + 6, its slope must be the negative reciprocal of the slope of y = 1/2x + 6. The negative reciprocal of a number is equal to the negative of the reciprocal of the number, so the slope of the line we are looking for is equal to -1 / (-5/2) = 2/5.
Next, we can use the point-slope form of a line to find the equation of the line that passes through the point (-9,3) and has a slope of 2/5. The point-slope form of a line is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. Substituting the values for the given point and the slope into this equation, we get:
y - 3 = 2/5(x - (-9))
y - 3 = 2/5(x + 9)
Next, we can distribute the 2/5 on the right-hand side of the equation to get:
y - 3 = 2/5x + 18/5
Finally, we can combine like terms on both sides of the equation to get the final equation of the line:
y=2/5x + 18/5 + 3
y=2/5x + 33/5

Work out the urface area of thi olid quarter-cylinder. Give your anwer in term of π
The total surface area of a solid quarter-cylinder is 10(13π + 32) cm².
Given:-
The radius of a solid quarter-cylinder = 10 cm.
Height of solid quarter-cylinder = 16 cm.
To calculate the surface area we have a formula:-
Total surface area of solid quarter-cylinder = (TSA of cylinder / 4) + 2(Area of rectangle)= 2πr(h + r)/4 + 2(r * h) = πr(h + r)/2 + 2rh .
Solution:-
r = 10 cm.
h = 16 cm.
So,
→ Area of rectangle so formed = r * h = 10 * 16 = 160 cm².
then,
→ Area of two rectangles so formed = 2 * 160 = 320 cm².
Therefore,
→ Total surface area of solid quarter-cylinder = πr(h + r)/2 + Area of two rectangles.
→ Total surface area of solid quarter-cylinder = π * 10 * (10 + 16) / 2 + 320
→ Total surface area of solid quarter-cylinder = 5π * 26 + 320
→ Total surface area of solid quarter-cylinder = 5(26π + 64)
→ Total surface area of solid quarter-cylinder = 5*2(13π + 32)
→ Total surface area of solid quarter-cylinder = 10(13π + 32) cm².
Hence, the Total surface area of a solid quarter-cylinder is 10(13π + 32) cm².

Property
The property illustrated in the statement "If ∠A ≅ ∠B, ∠B ≅ ∠C, then ∠A ≅ ∠C" is the Transitive Property.
This property states that if two elements are related by a certain relationship, and another element is related to the second element by the same relationship, then the first and third elements are related by the same relationship.
In this statement, the relationship is that of congruency, meaning that each angle has the same measure. Therefore, the Transitive Property states that if angle A is congruent to angle B, and angle B is congruent to angle C, then angle A is congruent to angle C.
The other three properties listed do not apply to this statement. The Reflexive Property states that a given element is related to itself by a certain relationship, which does not apply to this statement.
The Symmetric Property states that if two elements are related by a certain relationship, then the two elements are related to each other in the same way, which is not applicable in this statement.
Lastly, the Addition Property states that the sum of two elements related by a certain relationship is related to the two elements by the same relationship, which is not applicable in this statement.

Hannah, Ben, Stephanie, and Brayden bought a gift for their Mom. The total cost of the gift, including tax, was $64.80. Hannah paid $21, Ben paid 1/3 of the cost, Stephanie paid 15% of the cost, and Brayden paid the remaining cost. Who paid the greatest part of the cost?
Answer: Ben paid the most
Step-by-step explanation: Okay, to find the prices of the 4, we need to follow what the problem says. So, we know Hannah paid 21, so we know that is how much she paid. Now, we need to find 1/3 of the total cost ($64.80) So, we do 1/3 divided by $64.80 and get $21.60. For Stephanie, we need to find 15% of $64.80, so we can write it as a proportional relationship, so 15 x $64.80 / 100 is 9.27. (as a decimal) Now, we subtract all of those numbers from the total cost ($64.80) to find Brayden's pay. After I subtracted all of the amounts, I got $12.93. I'll list all the amounts.
Hannah - 21
Ben - 21.60
Stephanie - 9.27
Brayden- 12.93
So, as we see Ben paid the most. I hoped this LONG explanation helped you!
it should be ben.
Hannah paid $21;
ben paid 1/3 of 64.80 and that's $21.6 (64.84÷3);
Stephanie paid 15% of $64.80 and that's $9.72 (15÷100×64.80);
Brayden paid $12.48 [64.80-(21+21.6+9.72)].

The expected gain after 16 tosses of the coin is $400.
State the term equally likely events?Equally likely denotes the probability that each experiment's result will occur. For instance, if you throw a fair, six-sided die, any of the faces (1, 2, 3, 4, 5, or 6) has the same chance of coming up. A fair coin has an equal chance of landing on its head (H) or tail (T).Let x stand in for your entire savings.
There is a 0.5 likelihood of heads and a 0.5 possibility of tails. (equally likely events).
The value of accepting this offer is 1.5. The formula is as follows:
2 heads.
0.5 = P(Heads)
Value anticipated if the coin came out heads: 2x*0.5 = x
Plus
(1 - 0.5)x = 0.5x for tails.
0.5 = P(Tails)
Value anticipated if the coin came up tails: 0.5x*0.5 = 0.25x
Total projected value is equal to 1.25x.
For x = $20
Thus,
Amount = 1.25(20) = $25.
Thus, for the 16 tosses = $25 x 16 = $400.
