For this case, the first thing we must do is define variables.
We have then:
n: number of cans that each student must bring
We know that:
The teacher will bring 5 cans
There are 20 students in the class
At least 105 cans must be brought, but no more than 205 cans
Therefore the inequation of the problem is given by:
Answer:
105 < 20n + 5 < 205
the possible numbers n of cans that each student should bring in is:
105 < 20n + 5 < 205

2(P +1) + 3(P + 2 ) > 2
need help pls
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
[tex]2\left(P\:+1\right)\:+\:3\left(P\:+\:2\:\right)\:>\:2[/tex]
solving the expression
[tex]2\left(P\:+1\right)\:+\:3\left(P\:+\:2\:\right)\:>\:2[/tex]
as
[tex]2\left(P+1\right)+3\left(P+2\right)=5P+8[/tex]so the expression becomes
[tex]5P+8>2[/tex]
subtracting 8 from both sides
[tex]5P+8-8>2-8[/tex]
[tex]5P>-6[/tex]
Dividing both sides by 5
[tex]\frac{5P}{5}>\frac{-6}{5}[/tex]
[tex]P>-\frac{6}{5}[/tex]
Therefore,
[tex]2\left(P+1\right)+3\left(P+2\right)>2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:P>-\frac{6}{5}\:\\ \:\mathrm{Decimal:}&\:P>-1.2\\ \:\mathrm{Interval\:Notation:}&\:\left(-\frac{6}{5},\:\infty \:\right)\end{bmatrix}[/tex]

Keeley ordered 240 T-shirts to sell at the school carnival. She paid $3.20
per shirt, plus 5% of the total order for shipping. When she sells each T-
shirt at the carnival, she adds a 150% markup to the total price she paid for
the shirt (including the cost of shipping). What is the selling price of each T-
shirt?
Answer:
We have 200 shirts
Cost $2.80 each
plus a 5% charge for shipping.
Selling price
150% markup
Recall when we use percentages, we need to express them as decimals.
Michelle's cost for each shirt was
2.80 (1.05) = 2.94
The markup is
2.94 (1.50) = 4.41
The markup is added to the cost to get the final selling price.
2.94 + 4.41 = $7.35
Michelle will sell each shirt for $7.35.
Let’s reword the question to make it simpler to understand:
Keeley pays $3.20 per shirt + 5% for shipping.
She sells them at the carnival for 150% the price she paid.
First of all we should work out how much the 5% shipping cost Keeley.
If the shirts are $3.20 that means 10% is $0.32, to get 5% we divide that by 2. This means 5% is $0.16, therefore shipping is $0.16.
The total price Keeley pays per shirt is $3.20 + $0.16 = $3.36.
Now let’s find out 10% of $3.36, which is $0.336, then multiply that by 15 to get 150%:
5.04
Therefore Keeley sells each shirt for $5.04

Container A and Container B have leaks. Container A has 800 ml of water, and is leaking 6 mil per minute. Container B has 1,000 ml, and is leaking 10 mil per minute. Write and equation that would show how many minutes, m, it take for the two containers to have the same amount of water.
Answer:
50 minutes (I think)
Step-by-step explanation:
A= 800 - 6m
B = 1000 - 10m
800 - 6m = 1000 - 10m
4m = 200
50 = m

What is the radius of a circle that has a circumference of 3.14 meters?
Answer:
.5 meters
Step-by-step explanation:
to find the circumference the equation is C = 2(pie)r so if you have known circumference you would go circumferece (3.14) divided by 3.14(pie) times 2 to find the radius which is .5
Answer:
r=0.5m

If the transformation was a rotation, tiffany can or cannot be certain the trapezoids are congruent?
Answer: Tiffany can be certain the trapezoids are congruent.
Step-by-step explanation: Two figures are congruent when their corresponding angles are equal and they have the same shape and size.
A figure can go thorugh 3 types of transformations:
Rotation: the figure is turned around a fixed point;Reflection: is created by fliping over the figure over a line;Translation: move the figure to another location, without changing its size;As long the figure doesn't change its size or shape, it doesn't matter if it's rotated, reflected or translated, they will be congruent.
When the trapezoid was rotated creating another one, the two shapes didn't change its size or shape, so Tiffany can be certain they are congruent.

.6 is more than 1/2
.34 is less than 1/2
.812 is more
.9 is more
.099 is less
Step-by-step explanation:
1/2 as a decimal is .5 so anything larger than it will be .51 or greater and anything less will be .49 or less
Answer:
.6 is more than 1/2
.34 is less than 1/2
.812 is more than 1/2
.9 is more than 1/2
0.99 is more than 1/2
Step-by-step explanation: What is 1/2? 0.5. Look at the tenths place. Is the tenth higher than 5 or less than 5? But here is a warning: If you are comparing 1/2 and 1.4, 1.4 is greater than 1/2 because 1/2 is less than 1.
