128 Centimeters squared
192 Centimeters squared
256 Centimeters squared
512 Centimeters squared
Answer:
192cm²
Step-by-step explanation:
If you cut the shape into 2 and you do 8×8 which is 64cm²
Then you work out the area of the other part of the shape which is 8×16=128cm² then add them two together which is 192cm²

Area of a Circle
10 POINTS+BRAINLIEST
Answer:
Circle 1 = 24 pi in² = 452.2 in²
Circle 2 = 706.5 in²
Circle 3 = 271.6 in²
Step-by-step explanation:
In order to find the Diameter of a circle, you have to multiply the radius by 2. According to circle 1, 12in (radius) multiplied by 2 gets you 24 pi in².
In order to find the area, you multiply the radius² and then multiply it by pi or 3.14.
Is green the circumference or the diameter??? Had a little bit of confusion in that part, but I gave you the area only for Circle 2 and 3. For circle 1 I found the diameter (24 pi in²) and the area.

1. What is the total number of colored golf balls in Ashley’s collection?
2. What is the sample space?
S =
3. What is the theoretical probability that each event in the
sample space occurs?
Answer:
18 golf balls in all, 1/18 is the answer
Step-by-step explanation:
Answer:
1. 18
2. {blue, magenta, purple}
3. P(blue) = 1/2
P(magenta) = 7/18
P(purple) = 1/9

Step-by-step explanation:
subtract 10 on both sides
24-10=14
x=14
Answer:

Step-by-step explanation:
10 + x = 24
-10
x=14
( You subtract 10 from both sides. 24-10 =14. Therefore x =14
Polygon v has an area of 1 square unit. Jun-seo drew a scaled version of polygon v using a scale factor of 7 and labeled it polygon w
Answer:
The area of Polygon
W
WW is
49
4949 square units.
Step-by-step explanation: dk
Scale factors are used to enlarge or reduce the size of a shape
The area of polygon w is 49 square units
The area of polygon v is given as:
[tex]v =1[/tex]
The scale factor of the sides of polygon v, that forms polygon w is given as:
[tex]k=7[/tex]
The area of polygon w is then calculated as:
[tex]w =v\times k^2[/tex]
So, we have:
[tex]w =1\times 7^2[/tex]
Evaluate the exponents
[tex]w =1\times 49[/tex]
Multiply 1 and 49
[tex]w =49[/tex]
Hence, the area of polygon w is 49 square units

This diagram shows a block of stainless steel. The mass of the block is 930g.
Calculate the density of stainless steel.
Giving away brainliest! PLEASE HELP :)
Answer:
the answer is 7.75 g/cm3
Step-by-step explanation:
hope this helps
The density of the given block of stainless steel is 7.75 g/cubic cm. The value is obtained by the ratio of its mass to its volume.
What is the density of the cuboid?The cuboid has rectangular faces with length(l), width(w), and height(h). So, the density of the material which is required to make the cuboid is calculated as follows:
Density = mass/volume
Where the volume of the cuboid is the product of length, width, and height.
I.e., Density = mass/ (l × w × h)
Calculation:The given block has
length(l) = 8cm
width(w) = 5cm
height(h) = 3cm
The mass of the block is given as 930g
So, the density of the stainless steel is
Density = 930g/(8 × 5 × 3) cm³
= 930/120 (g/cm³)
= 7.75 g/cm³
Therefore, the density of the block is 7.75 g/cubic cm.

Plzzzzzzz help In the number 3.9928, how does the value of the 9 in the tenths place compare to the value of the 9 in the hundredths place? Drag and drop a fraction into the box to correctly complete the statement. The value of the 9 in the tenths place is the value of the 9 in the hundredths place.
Answer:
This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place
or
The value of 9 in the tenth place is 10 times the value of 9 in the hundredth place
Step-by-step explanation:
The decimal we are considering is 3.9928
The 9 in the tenth place has a value of 0.9
The value of 9 in the hundredth place has a value of 0.09
Now, what fraction of the 9 in the tenth place is the 9 in the hundredth place.
To mathematically get this, we just need to place the value of 9 in the hundredth place over the value of 9 in the tenth place;
Mathematically, that would be;
0.09/0.9 = 0.1 = 1/10
This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place
or
The value of 9 in the tenth place is 10 times the value of 9 in the hundredth place
