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.

Answer:
.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.

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
Which equation can be used to solve for x in the diagram?

18-(-6)
18+6
24
Answer:
The answer is 24.
Step-by-step explanation:
3x-2y if x =6 and y= -3
3 times 6 equals 18
2 times -3 equals -6
18-(-6)=24

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

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

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]

======================================================
Explanation:
The inequality sign has an "or equal to", which means the boundary line will be solid. We can rule out choices B and C because they have dashed boundary lines.
A solid boundary line means that points on the boundary are part of the solution set.
Now let's see what happens when we plug in a point like (x,y) = (4,0). This will tell us how to shade the blue region.
[tex]-5x + 4y \ge -1 \\\\-5(4) + 4(0) \ge -1 \\\\-20 \ge -1 \\\\[/tex]
This is false because -20 is not larger than -1. It's the other way around.
This tells us the point (4,0) is not in the blue shaded region, and it's not on the boundary line either. We can rule out choice A because of this.
The only thing left is choice D, which is the final answer. I recommend plugging a point from this region into the inequality to confirm we have a true statement.
