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
the perimeter is 194.6 units

3x - 5y = -35
please solve and show your work
Answers
First you subtract 3x to both sides.
3x - 5y = -35
-3x -3x
Then it would be
-5y = -3x -35
Then you divide -5 on both sides to isolate the y
-5y = -3x -35
/-5 /-5 /-5
Two negatives cancel out and make a positive so it would be
Y = 3/5x + 7

An image of a rhombus is shown.
a rhombus with a base of 18 centimeters and a height of 15.5 centimeters
What is the area of the rhombus?
16.75 cm2
33.5 cm2
139.5 cm2
279 cm2
Answers
Formula used,
Area of rhombus = Base × height
Substituting the values,
\( \longrightarrow\)Area = 18 × 15.5
\( \longrightarrow\) Area = 279 cm²
Therefore, 279 cm² is the area of the rhombus .
Answer:
D) 279 cm²
Step-by-step explanation:
Area of a rhombus formula:
\(A=bh\)
This formula is also used for squares and rectangles.
So, we can substitute in our values such as:
A=(18)(15.5)
simplify
A=279
Now, add our label and units:
A=279 cm²

Answer: The ratio is 18:3
Step-by-step explanation:
Answer: 6 to 1
Step-by-step explanation:
A ratio refers to a fraction. In this case the question asks how many players to coaches there are.
The word "to" means that is where the fraction bar goes.
Players/Coaches
There are 18 players and 3 coaches.
18/3
18 can be divided by 3, 6 times so the fraction can be simplified to
6/1 meaning there are 6 players for every coach.

The large solid below is made from small cubes. Each has a side length of 1/4.
Answer the questions below. Write your answers in simplest form.
(c) What is the volume of the large solid?
Answers
Answer:
A is 36 small cubes, because by looking at the image, you can see 3 rows of cubes containing 6 cubes each. So that would be 3 times 6, which is 18. There are 2 of these arrangements, one on top and the other on the bottom. So we multiply 18 by 2 to get 36 small cubes.
B is 1/64ft cubed, because the volume of a cube is length x width x height, and because each is the same (it is a cube) we take the length of the cube (1/8) and multiply it 2 times, to get 1/8 x 1/8 x 1/8 = 1/64 cubic feet.
C is 9/16 cubic feet for the volume of the entire cube. Because we know that there are 36 small cubes total, and we know that each cube is 1/64 cubic foot in volume, we multiply 36 small cubes, by their volume, 1/64 feet cubed to get the fraction of 9/16 .
Step-by-step explanation:
Answer:
3/4 x 6/4 x 2/4
Step-by-step explanation:
You need to multiply length * width * height to find volume.
Since each cube is 1/4, we have to multiply 3 for the width.
3 x 1/4 = 3/4.
Since there are 6 cubes for the length, you have to multiply 6 x 1/4 = 6/4
Finally, since the height is 2 cubes, you have to do 2 x 1/4 = 2/4
Finally, you multiply them all.
3/4 x 6/4 x 2/4

------------------
28.6925
Answer: $28.69
Explanation:
Although it is usually used to describe an Italian dish of noodles with sauce, spaghetti can also be used as slang to describe an embarrassing act, general awkwardness, or faux pas. When this occurs, it is referred to as "dropping" spaghetti.
Spaghetti is a traditional Italian pasta. It is made of durum wheat semolina and is long and round in cross-section, like a string hence the name, as spago means string. Although commercial varieties are widely used, artisanal versions are widely available.
While it's unclear who or when coined the term "spaghetti code," it was being used to describe a tangled mess of code lacking structure by the late 1970s. In the 1980s, the term appeared at least once in a whitepaper.
Thus, option B is correct.
