Answer: I believe it is 508 cm²
Step-by-step explanation:
Start out by finding the surface area (SA) of the 2 shapes. The formula for SA is 2(wl + wh + wh).
Blue shape: 2(12x2 + 12x10 + 2x10) = 328 cm²
Red shape: 2(8x3 + 8x6 + 3x6) = 180 cm²
Now that the surface area of both shapes are solved, just add them together and you will get the answer of 508 cm²

The volume of a large Tank is 126 yd(3). It is 2 2/5 wide and 2 4/5 high. What is the length of the Tank?
Answers
Hi! I'd be happy to help you find the length of the tank. To find the length, we'll use the formula for the volume of a rectangular prism: Volume = Length × Width × Height.
The volume of the tank is 126 cubic yards, the width is 2 2/5 yards, and the height is 2 4/5 yards. First, let's convert the mixed numbers to improper fractions:
Width: 2 2/5 = (2 × 5 + 2) / 5 = 12/5 yards
Height: 2 4/5 = (2 × 5 + 4) / 5 = 14/5 yards
Now, we'll plug these values into the volume formula and solve for the length:
126 = Length × (12/5) × (14/5)
To isolate the length, divide both sides of the equation by (12/5) × (14/5):
Length = 126 / [(12/5) × (14/5)]
Length = 126 × (5/12) × (5/14)
Length = (126 × 5 × 5) / (12 × 14)
Length = 630 / (168)
Length = 3.75 yards
The length of the tank is 3.75 yards.

A: 38 tickets
B: 44 tickets
C: 236 tickets
D: 280 tickets
Answers
Answer:
b is the answer
Step-by-step explanation:
lets make ‘ x ‘ the number of tickets he should sell on the final day.
make into a fraction;
[tex]\frac{37+29+27+50+45+38}{7} = 40[/tex]
37 + 29 + 27 + 50 + 45 + 38 = 280
236 + ‘ x ‘ = 280
⇒ ‘ x ‘ = 280 - 236
‘ x ‘ = 44
b being the answer

A composite figure has a radius of 10 cm.
A circle with radius of 10 centimeters. One-quarter of the circle is cut out of the figure.
What is the area of this composite figure? Use 3.14 for Pi.
23.55 centimeters squared
78.5 centimeters squared
235.5 centimeters squared
314 centimeters squared
Answers
Answer:
C, 235.5 cm^2
Step-by-step explanation:
Formula for area of circle:
A = πr^2
Where π represents pi(3.14 or 22/7) and r represents the radius.
Plug in given value (10):
A = πr^2
A = 3.14(10)^2
A = 3.14(100)
A = 314
Now they say a quarter of this circle is cut out, which means we have to first find out what a quarter of this area is:
314/4
= 78.5
A quarter of this circle is 78.5, so let's subtract this from the total area (314):
314 - 78.5
= 235.5 cm^2
The area is 235.5 centimeters squared.

2. Pencils measuring less than 5 inches: 3 + 2 + 3 = 8 inches in total.
3. False. To determine if more than half of the pencils are 6 inches or shorter, we need to find the total number of pencils and calculate how many of them are 6 inches or shorter.
Total number of pencils = 4 + 3 + 2 + 3 + 7 + 8 = 27
Number of pencils that are 6 inches or shorter = 4 + 3 + 2 + 3 = 12
To find out if more than half of the pencils are 6 inches or shorter, we need to divide the number of pencils that are 6 inches or shorter by the total number of pencils and multiply by 100%:
12/27 x 100% = 44.44%
Since 44.44% is less than 50%, the statement is false.
4. There are three pencils that measure more than 5.5 inches but less than 7.5 inches: 6, 6, and 7. Therefore, the answer is 3 pencils.

Stephen has $500 in an account for 9 months at a compound interest rate of 7.5%. At the end of 9 months, how much money is in his account?
Answers
Answer:
8.12
Step-by-step explanation:
Stephen has approximately $532.72 in his account at the end of 9 months with a 7.5% compound interest rate.
We can use the formula for compound interest to find the amount of money in Stephen's account at the end of 9 months:
A =P [tex](1 + r/n)^_(nt)[/tex]
where:
A is the amount of money in the account at the end of the period
P is the principal (initial amount) in the account
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year
t is the time (in years)
We know that P = $500, r = 0.075 (since the interest rate is 7.5%), n = 12 (since the interest is compounded monthly), and t = 9/12 (since 9 months is three-quarters of a year). Substituting these values into the formula, we get:
A = [tex]$500(1 + 0.075/12)^_{(12*(9/12))[/tex] = [tex]$532.72[/tex]
Therefore, Stephen has approximately $532.72 in his account at the end of 9 months.

Write the following expression in simplest form.

9.6a + (−2)
15.4a + (−2)
15.4a + (−14)
PLS HELP ME
Answers
Answer:
9.6a + (−2)
Step-by-step explanation:
To simplify the expression (6 + 12.5a) - (8 + 2.9a), you'll need to distribute the negative sign inside the parentheses and then combine like terms:
(6 + 12.5a) - (8 + 2.9a) = 6 + 12.5a - 8 - 2.9a
Now, combine the like terms:
(12.5a - 2.9a) + (6 - 8) = 9.6a - 2
So, the simplest form of the expression is 9.6a - 2.

Answers
Answer:
Team C appears to have the larger mean weight.
Step-by-step explanation:
After seeing the dot plot of two teams i.e. Team C and Team D the conclusion that can be drawn regarding the larger mean of the team is that:
Team C is expected to have larger mean since the dots are for the higher values of weights and hence will result in higher mean. whereas for team D the dots or frequencies are for smaller weights and hence will result in a less mean as compared to team C.
Hence, Team C appears to have the larger mean weight.

Answer to 3rd image = b: the area of the circle is approximately 3 times greater than the circumferance
Explanation:
Circumferance =
[tex]\pi d[/tex]
Using this we can figure out that the circumferance is 37.704 cm or if we round it then it will be 38 cm.
Area of a circle =
[tex]\pi r^{2} [/tex]
Using this we can find that the area would be 113.112 cm² or if we round it, it becomes 114 cm².
Now let's go through the statements:
A) We know that there's no way that area is 8 times larger than circumferance because it would be 304 cm
C) The circumferance can't be an eight of the area as its approximately 4 times smaller.
D) The circumferance can't be 4 times greater as its 4 times smaller and its less than the area
We are left with B) which is the answer because 4 times the curcumferance would be 152 cm which is close enought to the area
so B) is the answer
For 4th image the answer is A) 15.7 / pi = d
Explanation:
We know that to find circumferance we use the formula:
pi d = circumferance
so we know that the circumferance is 15.7 cm so we are going to do the opposite.
pi = 3.142
If we do 15.7 / 3.142 we get 5 rounded up and we can check for any mistakes by doing 5 pi and its correct because we get 15.71 cm which is the same as 15.7 cm
so the answer is A)
Answer:A
Step-by-step explanation:
4th image the answer is A) 15.7 / pi = d
the formula:pi d = circumferance
we know that the circumferance is 15.7 cm so you can do the opposite.
pi = 3.142
If we do 15.7 / 3.142 we get 5 rounded up and we can check for any mistakes by doing 5 pi and its correct because we get 15.71 cm which is the same as 15.7 cm

A right rectangular prism has length 3 1/3 , width 2 1/3 , and height 1 1/3 . You use cubes with fractional edge length 1/3 to find the volume. How many cubes are there for each of the length, width, and height of the prism? Find the volume.
Answers
For the length, we have:
3 1/3 ÷ 1/3 = 10
So there are 10 cubes along the length of the prism.
For the width, we have:
2 1/3 ÷ 1/3 = 7
So there are 7 cubes along the width of the prism.
For the height, we have:
1 1/3 ÷ 1/3 = 4
So there are 4 cubes along the height of the prism.
To find the volume of the prism, we can multiply the number of cubes along each dimension.
Volume = length × width × height
Volume = 10 × 7 × 4
Volume = 280 cubic units
So the volume of the prism is 280 cubic units.
