Find the surface area of the composite figure.
3 cm
12 cm
2 cm
6 cm
10 cm
8 cm
Answer:
I think it is 34,560
Step-by-step explanation:
3 x 12 x 2 x 6 x 10 x 8 = 34,560
The surface area of the given figure is 394 square cm.
What is a surface area?Surface area refers to the total area that the surface of a three-dimensional object occupies. It is the sum of the areas of all the faces or surfaces of the object. Surface area is usually measured in square units, such as square meters (m²) or square feet (ft²).
The surface area will be calculated by calculating the area of each face and then adding all the areas,
SA = 2 ( 2 x 12 ) + 2 ( 2 x 10 ) + ( 8 x 6 ) + 2 ( 3 x 8 ) + ( 3 x 6 ) + ( 12 x 16 )
SA = 48 + 40 + 48 + 48 + 18 + 192
SA = 394 square cm.
Therefore, the surface area of the figure will be 394 square cm.

- What is the volume of a square pyramid with height 15m and slant height 17m?
A 85 m2
B 320 m2
C 1280 m2
D 3840 m2
Answer:
c ) 1280 m^3
here,
slant height (s)= 17m
vertical height ( h)= 15m
length (a)= ?
so,
s^2 = (a/2)^2 + h^2
(17)^2 = (a/2)^2 + 15^2
64 = (a/2)^2
8^2= (a/2)^2
8×2 = a so a = 16
Now we know
volume of pyramid
= 1/3 × a^2 × h
= 1/3 × 16^2 × 15
= 1/3 × 256 × 15
= 1280 m^3
11. Shrimp are often found in tropical climates and can be raised on farms or caught in the wild.
Elena was taking inventory of 1-pound shrimp packages at the end of the day at a seafood
market. She recorded the country of origin and whether the package contained shrimp that
were farm-raised or wild-caught.
• 27 packages of shrimp were farm-raised in Mexico.
• 40 packages of shrimp were farm-raised in Honduras.
• 52 packages of shrimp were farm-raised in Ecuador.
• 13 packages of shrimp were wild-caught in Mexico.
6 packages of shrimp were wild-caught in Honduras.
• 28 packages of shrimp were wild-caught in Ecuador.
a. A package of shrimp is selected at random from those inventoried. What is the probability
that a package of wild-caught shrimp came from Honduras?
The probability that a package of wild-caught shrimp came from Honduras is 0.0036.
How to calculate the probability?The probability that a package of wild-caught shrimp came from Honduras will be:
= Number of wild caught in Honduras/ Total number
= 6/(27 + 40 + 52 + 13 + 6 + 28)
= 6/166
= 0.036

Answer:
B ig
Step-by-step explanation:
A: 3(2x+7) = 6(X+4) - 3
<=> 6x+ 21 = 6x + 24 - 3 = 6x + 21
<=> 0 = 21 - 21 = 0
B: 3(6x-5)= 3(6x-5)+x
<=> 18x-15= 18x - 15 + x = 19x - 15
<=> 0 = x
C: 8(x-3) + 14= 2(4x+5)
<=> 8x - 24 + 14 = 8x - 10 = 8x + 10
<=> 0 = 0
D: 13x - 7 = 12( x - 1) +x + 5
<=> 13x - 7 = 12x -12 + x + 5 = 13x - 7
<=> 0 = 0

The U.S. Federal Seed Act establishes germination rates for various fruit and vegetable seeds. Watermelon seeds are to meet a 70% germination standard. A skeptical gardener who has not had very good luck planting watermelons believes that the seed company he purchases seeds from is not adhering to the 70% federal mandate. Once a week for 12 weeks, he purchases a pack of 10 watermelon seeds to act as his sample. He plants the seeds in a greenhouse with good soil to maintain a consistent temperature and watering routine. He finds that the germination rate for the company's watermelon seeds is 55%. Is this convincing evidence that the proportion of watermelon seeds that germinate is less than 70%

what’s the value of x ?
Answer:
x=70
Step-by-step explanation:
Because these angles are on the opposite sides of each other, they have to add up to 180. This will make the equation 2x-5+45=180. Simplify this to get 2x+40=180. Subtract 40 from both sides to get 2x=140. Divide each side by 2 to isolate x. x=140/2. Simplify this to get x=70.

Lexi is hiking a trail that is 7.5 miles long. She stops to take a break after hiking 3.8 miles of the trail. Which equation can be used to find how many miles, m, Lexi has left to hike
Answer:
7.5 - 3.8 = m
Step-by-step explanation:
The equation can be used to determine the number of miles (m) Lexi has left to hike will be m + 3.8 = 7.5.
What is subtraction?It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
Lexi is hiking a trail that is 7.5 miles long. She stops to take a break after hiking 3.8 miles of the trail.
Then the equation can be used to determine the number of miles (m) Lexi has left to hike will be
Let m be the number of miles left. Then we have
m + 3.8 = 7.5
Subtract 3.8 on both sides, then we have
m = 3.7

A number,M, is rounded to 1 decimal place. the result is 9.4 complete the error interval for M
Answer:
[tex]9.35 \le M \le 9.45[/tex]
Step-by-step explanation:
Given
[tex]M = 9.4[/tex] to 1 d p
Required
The error interval
The error interval is represented as:
[tex]Lower \le M \le Upper[/tex]
Where
[tex]Lower = M - 0.05[/tex]
[tex]Upper = M + 0.05[/tex]
So, we have:
[tex]Lower = M - 0.05[/tex]
[tex]Lower = 9.4 - 0.05[/tex]
[tex]Lower = 9.35[/tex]
[tex]Upper = M + 0.05[/tex]
[tex]Upper = 9.4 + 0.05[/tex]
[tex]Upper = 9.45[/tex]
Hence, the error interval: [tex]Lower \le M \le Upper[/tex] is:
[tex]9.35 \le M \le 9.45[/tex]
