Answer:
Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units

A cardboard box has a volume that is 6,336 cubic inches. A company creates a new design with the same proportions, but instead the dimensions are One-fourth the dimensions. Explain how you can find the volume of the new design without knowing the dimensions.
Answer:
Cube the scale factor 0.25. Then multiply the volume of the box by 0.015625.
Answer:
Since the dimensions have a proportional relationship, the new volume can be calculated using the original volume and the scale factor. The new volume will be the cube of the change, which is 1
64
. The new volume is the product of 6,336 and 1

Answer:
B and D
Step-by-step explanation:
If you count all of the dots, you see that the total amount of math books is 12.
Then, look at the column between 2 and 2 2/8. You see that there are 2 books that weigh 2 1/8 pounds.
Therefore, there are 2 out of the 12 books that weigh 2 1/8 pounds.
2/12 can also be simplified down to 1/6.
can someone help? im not sure about this questons and its getting me so stressed out :( pls help :(
Answer:
Lets start:
Picture 1:-
1. Length of EH= 12cm
2. Angle G= 55 degrees
Picture 2:-
1. Scale factor= 1/4 (I'm not sure about this but this is what I think it is ;-;)
2. Value of y= 28 cm
Picture 3:- [Picture 3 is cropped so I'm guessing its the last one so imma answer those questions :D]
1. Scale factor= 5 (Again I'm not sure but its my best guess)
2. Value of z= 5
Picture 4:-
1. Scale factor= 4 (I'm pretty sure you know that my scale factor answers are guesses so yea ;-;)
2. Value of b= 12

It'll help you understand how we solve these questions
Well anyways i hope this clears your concepts :D
Answer:
Step-by-step explanation:
EH is 12cm as the shape has been enlarged by scale factor two (all sides have been multiplied by 2).
Angle G remains the same at 55 degrees.
PART A
Scale factor for the triangle = 1/4
Value of y = 28cm
3) z = 5, scale factor = 5
SIMILAR RECTANGLES:
Scale factor = 4
Side b = 12cm

A box contains several copies of Mrs. Spencer's new pamphlet. The box weighs 2,000 grams. This chart shows the effect of adding or taking away a pamphlet. Pamphlets Added to the box(x) Effect on the Box's Weight (y) 0 0 1 6 2 12 3 18 Is this an example of continuous or discrete data? discrete continuous
Answer:
This example represents discrete data.
Step-by-step explanation:
Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.
In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.
Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.
Lyndie is making reduced copies of a photo 25 centimeters in height. She sets the copy machine to an 80% size reduction.
PART A
Write a percent equation that represents the relationship of the height of the first copy to the height of the original photo.
PART B
Lyndie wants to make another copy that will have a height of 17 cm. The copy machine settings increase or decrease in increments of 5%. Which photo should she make her copy from, the original or her first copy? Explain.
Answer:
80% x 25cm = 20cm
First Copy
Step-by-step explanation:
80% x 25cm = 20cm
1.25 is 5% of 25 25-17=8
8/1.25= 6.4 which doesn't go in evenly.
1 is 5% of 20 20-17=3
3/1= 3 which goes in evenly.

I need help with this question, I'm not very good at math and all help is appreciated!
Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

Gina is hiking from the top of a mountain. In 24 minutes, she walks down the mountainside to a location 1,524 feet from the top of the mountain. If she walks at about the same pace, express Gina’s average change in altitude per minute.
Answer:
The change in altitude per minute is 63.5 alt/ min
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
In 24 minutes = 1524 feet
So, the average Change in altitude per minute
=1524/24
= 63.5 alt/ min
hence, change in altitude per minute is 63.5 alt/ min.

Hozumi and Petra each own a hybrid car. They decide to compare the gas mileage for each, and kept track of the weekly average fuel efficiency (in mpg, miles per gallon) for a period of 8 weeks. The results are shown in the tables.
a. 1.45
b. 2.25
c. 3.92
d. 5.37
Answer: 1.45
Step-by-step explanation
It probably should be 1.45 I suppose since if you look at the graph, there is 3 - 39 and in the second, 3 - 52 so if you divided 39 by 3 you'd get 14 and if you divided 52 by 3 you'd get 17.3333333 and if you divided 17.3333333 by 14, you'd get 1.23809523571, which is closest to 1.45. I think that this is probably the answer.

Have a nice day and if you could mark me as brainllest I would be happyExplain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

Simplify -15- |-7.5|
Answer:
-22.5
Step-by-step explanation:
-15- |-7.5|
after taking the absolute value off, -7.5 would become positive 7.5. But then the negative outside the absolute value makes it negative again.
-15-7.5
=-22.5
The simplified expression -15 - |-7.5| is equal to -22.5.
To simplify the expression -15 - |-7.5|, we'll follow these steps:
Evaluate the absolute value: |-7.5|.
The absolute value of a number is its distance from zero on the number line. In this case, |-7.5| is equal to 7.5 because 7.5 units away from zero.
Substitute the absolute value into the expression:
-15 - 7.5.
Perform the subtraction:
-15 - 7.5 = -22.5.
Therefore, the simplified expression -15 - |-7.5| is equal to -22.5.
