The shape congruent to given figure is Figure 4.
Option D is correct.
What is congruency?Congruent figures have sides that are the same length and angles that are the same measurement. In other terms, two figures are said to be congruent when they are superimposed upon one another. Even when they are flipped or rotated, they perfectly fit on top of one another.
We have a figure which is similar to parallelogram.
First, figure is seems to be rectangle and do not have same unit measurement which is not Congruent.
Now, the second has more width than given figure.
Now, Third figure is also a rectangle and cannot be congruent.
Now, the fourth figure is similar to given figure.

There are 9 apples and 24 plums in a fruit bowl. What is the ratio of plums to apples?
Answer:
24:9 or 24 to 9 or [tex]\frac{24}{9}[/tex]
Step-by-step explanation:
The amount of plums is 24. The amount of apples is 9. So to write the ratio of plums (24) to apples (9), you write 24 to 9. You can either write a colon - 24:9 - a to - 24 to 9 - or as a fraction - [tex]\frac{24}{9}[/tex]. But, you have to write it with plums first.

Determine two pairs of polar coordinates for the point (5, -5) with 0° ≤ θ < 360°
Answer:
Step-by-step explanation:
x=5
y=-5
Hence it lies in 4th quadrant.
x=r cos θ
5=r cos θ ...(1)
y=r sin θ
-5 =r sin θ ... (2)
square and add
(5)²+(-5)²=r²(sin ²θ +cos ²θ )
r²=25+25=50
r=±5√2
dividing
tan θ=-5/5=-1=-tan 45°=tan (180-45),tan(360-45)
θ=135°,315°
so polar coordinates are (5√2,315°) and (-5√2,135°)

Adam has 3 coins in his pocket and they are all different from each other. Ben has 3 coins in his pocket and they are all the same as each other. Adam has half as much money as Ben.
What are the coins they each have?
Answer:
The possible coins are:
P = penny = $0.01
N = nickel = $0.05
D = dime = $0.10
Q = quarter = $0.25
H = half dollar = $0.50
We know that Adam has 3 coins in his pocket, and all of them are different, then the money that Adam has can be represented with (A + B + C)
Behn has 3 coins, and all of them are the same, then if his coin has a value X, he has a total of 3*X
We know that Adam has half as much money as Ben, this can be written as:
(A + B + C) = 3*X/2
The easier way to solve this, is to play with different values of X, and see if we can find the values of A, B and C.
For example, if X = $0.10
then:
(A + B + C) = $0.10*(3/2) = $0.15
We can find 3 different value of coins for this equation? No, we cant, so X = $0.10 is also discarded.
if x = $0.50 then:
(A + B + C) = (3/2)*$0.50 = $0.75
Here we could have:
A = $0.50
B = $0.25
then: A + B = $0.75
But we still have the coin C.
If we take X = $0.25 then:
(A + B + C) = (3/2)*$0.25 = $0.375
We could round the right part to $0.40
then the coins in the left part would be:
A = $0.25
B = $0.10
C = $0.05
A + B + C = $0.25 + $0.10 + $0.05 = $0.40
This is a strech, but is the only thing we can make with the given problem.

A five-gallon bucket was completely filled with water. The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes. If the leak continues at the same rate, how long will it take for the bucket to become half full? 1 gal = 128 fl oz
Answer:
600 minutes
Step-by-step explanation:
We start with a bucket that is completely full- it has five gallons of water.
5 gallons of water = 5 (128) fl oz = 640 fl oz
Half of 640 fl oz is 320 fl oz, which is the amount we are looking for.
So, we divide [tex]\frac{320}{8}[/tex] to find how many times it will take for the bucket to become half-full, which is 40 times.
Now, we multiply 40 by 15 minutes, so we get 40 × 15 = 600 minutes
Time for the bucket to become half full is 600 minutes.
Here,
A five-gallon bucket was completely filled with water.
The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes.
We have to find the time for the bucket to become half full.
What is Number system?
A number system is defined as a system of writing to express numbers.
Now,
A five-gallon bucket was completely filled with water.
The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes.
Hence, We start with a bucket that is completely full- it has five gallons of water.
So, Amount of 5 gallons of water = 5 * 128 = 640 fl oz
Now, Half of 640 fl oz = 640/2 = 320 fl oz
So, we divide to find how many times it will take for the bucket to become half-full as;
⇒ 320 ÷ 8 = 40
Now, Time is calculated as to multiply 40 by 15 minutes,
⇒ 40 × 15 = 600 minutes
Hence, Time for the bucket to become half full is 600 minutes.

Step-by-step explanation:
5. each time in the table you multiply H by 6 2/5 ex.
column 4 , 100x6=600, 2/5 of 100 = 40 and the total is 640, so the contant of proprtionality is 6 2/5

Step-by-step explanation:
When multiplying the rectangle's sides by 1.5 you get the rectangle F.
When multiplying the sides by 1/4 you get G.
When multiplying by 1.25 you get H.
To get J, you would need to muliply 8 by 1.25 and 2 by 2. There is no scale factor that would result in the rectangle ABCD turning into J.
i think of a number multiply it by three and add four i get twenty two.

Solve each system by substitution.
y=-4x-9 y=3x+19
Answer:
x=-4, y=7
Step-by-step explanation:
According to the first equation, y = -4x - 9, so we can substitute y in the second equation for -4x - 9.
y = 3x + 19
-4x - 9 = 3x + 19
Add 9 to both sides
-4x = 3x + 28
Subtract 3x
-7x = 28
Divide by -7
x = -4
Plugging this into the equation, we have:
y = -4x - 9
y = -4(-4) - 9
y = 16 - 9
y = 7
