Scientific notation means to write the answer in standard form. standard form helps you to express numbers that are too big or too small to be conveniently written in decimal form.
so for this case, it will be 4.571×10^-4.
when the number is decimal, you move the dot to the right and it will always be multiplying 10 to the power of a negative power.

Step-by-step explanation:</h2>
Sally has 6 red flags, 4 green flags, and 2 white flags.
i.e. there are a total of 12 flags.
Now, we are asked to find the different number of arrangements that may be made with the help of these 12-flags.
We need to use the method of permutation in order to find the different number of arrangements.
The rule is used as follows:
If we need to arrange n items such that there are number of items of one type, items same of other type .
Then the number of ways of arranging them is:
Hence, here the number of ways of forming a flag signal is:
( since 6 flags are of same color i.e. red , 4 flags are of green color and 2 are of white colors )
Answer:
D. 1356.5 cm³
Step-by-step explanation:
The volume of a cone can be represented by:
V = (π)(r²)(h/3)
Substitute the known values:
π = 3.14
r = 12
h = 9
V = (3.14)(12²)(9/3)
Square 12.
V = (3.14)(144)(9/3)
Divide 9 by 3.
V = (3.14)(144)(3)
Multiply 3.14 and 144.
V = (452.16)(3)
Multiply 452.16 and 3.
V = 1356.48
Round to the nearest tenth.
V = 1356.5.

Answer:
Hello! answer: 39
Step-by-step explanation:
Formula for triangles area: base × height ÷ 2
Formula for squares area: base × height
5 × 3 = 15 15 ÷ 2 = 7.5 since there are 4 triangles that are the exact same I will just multiply by 4 so I have all the triangles so 7.5 × 4 = 30 now the square is just 3 × 3 so... 3× 3 = 9 now we add these up 30 + 9 = 39 therefore the surface area is 39
