Answer:
they have to be congruent
Step-by-step explanation:
both rectangles have the same perimeter which means there Identical
If two rectangles have the same perimeter, they
do not have to be congruent is the correct option.
Given,
If two rectangles have the same perimeter.
We need to find whether both rectangles are congruent.
What is the perimeter of a rectangle?The perimeter of a rectangle is given by:
P = 2 ( Length + width )
Now,
Let the two rectangles be A and B.
Rectangle A:
Let,
Length = 2
Width = 4
Now,
Perimeter = 2 ( 2 + 4 ) = 2 x 6 = 12
Rectangle B:
Let,
Length = 3
Width = 3
Now,
Perimeter = 2 ( 3+ 3 ) = 2 x 6 = 12
We see that both rectangles have the same perimeter even if they have different lengths and widths so the rectangles need not be congruent.
Thus,
If two rectangles have the same perimeter, they do not have to be congruent.

On the previous problem, you found a unit rate of ounces per box. Explain how you find a unit rate when given a rate.
Answer:
A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.
Answer:
First, I would write the rate as a fraction. Then I would divide the numerator by the denominator.

2. 5x10= 50
Two right triangles:
1. 10x6/2= 30
2. 10x6/2= 30
Then you add them all up:
30+50+30+30= 140 sq. units
The total surface area of the given figure is 168 square units.
Given that, the net has the two triangles are right triangles. All quadrilaterals are rectangles.
We need to find the surface area in square units for the given figure.
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
There is a different surface area formula for every geometrical shape, but the idea behind all is to get the total area occupied by all the faces of the objects.
Now, the area of the triangle=1/2 × Base × Height
=1/2 × 8 × 6=24 square units
Area of 2 triangles=2 × 24=48 square units
Area of rectangle = Length × width
Now, the area of a rectangle with dimensions length=10 units and width=5 units.
Area=10 × 5=50 square units
The area of a rectangle with dimensions of length=8 units and width=5 units.
Area=8 × 5=40 square units
The area of a rectangle with dimensions of length=6 units and width=5 units.
Area=6 × 5=30 square units
Total surface area=48+50+40+30 square units
=168 square units
Therefore, the total surface area of the given figure is 168 square units.

One tutor for every 12 students.
Answer:
76
Step-by-step explanation:
so the first bit you don't even need its trying to trick you
first you do 72/6= 12 so that means for every 12 students, you need one tutor
then you do 120-72=48 and that means there are 48 students that have no tutor
to find out how much more tutors you need, do 48÷12= 4, meaning you need 4 extra tutors for the 48 more kids.
last you add 72 witch is the about of tutors you started with, to 4 witch is how much you just got.

B. Multiply by a power of 10 until both numbers have the same place values.
C. Multiply by a power of 10 until the divisor is greater than the dividend.
D. Multiply by a power of 10 until the dividend does not have any more decimal places.
when dividing by a decimal,
Multiply by a power of 10 until you are dividing by a whole number.
Explanation
Lets see what power of 10 to multiply a divisor and dividend by when dividing by a decimal
For example
[tex]\frac{34}{2.5}[/tex]
Here we have divisor 2.5 that has 0ne decimal place
So we multiply the divisor by 10 to remove the decimal point
we multiply both top and bottom by 10. so that decimal gets removed from the divisor
[tex]\frac{32}{0.32}[/tex], here we multiply the divisor by [tex]100 \; or \; 10^2[/tex] so that the decimal in the divisor will be removed.
S0, Multiply by a power of 10 until you are dividing by a whole number.

What is triangle?A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given are three triangles ΔABC, ΔDEF, ΔIHG.
ΔDEF is congruent to ΔGHI as -
EF = IH (given)
∠E = ∠H (right angle)

Which sequences of transformations confirm the congruence of shape II and shape I?
a reflection of shape I across the x-axis followed by a 90° clockwise rotation about the origin
a reflection of shape I across the x-axis followed by a 90° counterclockwise rotation about the origin
a reflection of shape I across the y-axis followed by a 90° counterclockwise rotation about the origin
a reflection of shape I across the y-axis followed by a 90° clockwise rotation about the origin
a reflection of shape I across the x-axis followed by a 180° rotation about the origin
Answer: D.), A.) A reflection of the shape across the y-axis and an 180 degree rotation around the orgin
Step-by-step explanation:
We will start answering this question by considering at the options.
1. When we reflect the shape I along X axis it will take the shape I in first quadrant, and then if we rotate the shape I by 90° clockwise, it will take the shape again in second quadrant . So we are not getting shape II. This Option is Incorrect.
2. Second Option is correct , because by reflecting the shape I across X axis and then by 90° counterclockwise rotation will take the Shape I in second quadrant ,where we are getting shape II.
3. a reflection of shape I across the y-axis followed by a 90° counterclockwise rotation about the origin takes the shape I in fourth Quadrant. →→ Incorrect option.
4. This option is correct, because after reflecting the shape through Y axis ,and then rotating the shape through an angle of 90° in clockwise direction takes it in second quadrant.
5. A reflection of shape I across the x-axis followed by a 180° rotation about the origin takes the shape I in third quadrant.→→Incorrect option
→→Out of Five option given , Option (2) and Option (4) are true options.

Chad created a table that shows the ratio of his role playing game cards.
Chad’s Cards
Card Type
Attack
Defense
Healing
Damage
Quantity
3
4
1
2
Next, Chad created this graph with ordered pairs that show the possible ratios of the number of damage to defense cards in his deck. What error did Chad make?
On a coordinate plane, a graph titled Chad's Cards has Damage on the x-axis and Defense on the y-axis. Points (1, 2), (2, 4), (3, 6), and (4, 8) are plotted.
Chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
Chad should not have included the values (1, 2) and (3, 6) because the ratio would be different for these points.
Chad should have changed the axes for the defense and damage cards so it was the same order as the table.
Chad needs to switch the order of each (x, y) value to show the decreasing values of the damage cards.

Step-by-step explanation:
A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 7 feet per second. The elevator for the miners descends 16 feet per second. One day, the equipment elevator begins to descend. After 27 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 11 seconds? At that time, which elevator is deeper? please answer a simple answer for grade 7
Step-by-step explanation:
Time for equipment elevator = 11 seconds + 27 seconds = 38
Time for elevator for miners = 27 seconds
Speed of equipment Elevator = 7 feet/ sec
Speed of Miner elevator = 16 feet/ sec
Distance traveled by Equipment Elevator = Speed * time
= 7 * 38 = 266
Distance traveled by Miner Elevator = Speed * time
= 16 * 11 = 176
266 > 176
Therefore, The Equipment Elevator is deeper than the Miner Elevator
Depth of Equipment Elevator = 266m
Depth of Miner Elevator = 176m

Abe is buying wrapping paper.
He is shopping for the best deal.
Drag the rolls of wrapping paper in order from the least to the greatest unit cost in dollars per square foot. (Just put from least to greatest)
Red: 12.5 square feet for $1.79
Blue: 40 square feet for $5.29
Green: 50 square feet for $8.49
Orange: 60 square feet for $6.00
Answer:
8.49
6.00
5.29
1.79
Step-by-step explanation:
Answer:
Orange, Blue, Red, Green.
Orange would be the best deal.
Step-by-step explanation:
In order to put the unit costs per square foot from least to greatest, let's find the unit cost per square root of each wrapping paper.
To find the unit cost per square root, we simply have to divide the cost over the amount of square feet. So:
Red:
[tex]c=\frac{1.79}{12.5}=\$0.1432\text{ per square foot}[/tex]
Blue:
[tex]c=\frac{5.29}{40}=\$0.13225\text{ per square foot}[/tex]
Green:
[tex]c=\frac{8.49}{50}=\$0.1698\text{ per square foot}[/tex]
Orange:
[tex]c=\frac{6}{60}=\$0.10\text{ per square foot}[/tex]
So, to cost of wrapping paper per foot from least to greatest is:
Orange, Blue, Red, Green.
So, orange would be the best deal.
And we're done!
