Answer:
(pi)(n^2 - n^2)
Step-by-step explanation:
A = (pi)r^2
r = n
A_n = (pi)n^2
r = m
A_m = (pi)m^2
A_sombreada = A_n - A_m =
= (pi)n^2 - (pi)m^2
= (pi)(n^2 - n^2)

Answer:
0.6
Step-by-step explanation:
The third side of the triangle ABC is AB. Using the Pythagorean Theorem, its length is 12. [tex]12^{2} +16^2=20^2[/tex]
∠F is congruent to ∠C and so the sin(∠F) = sin(∠C)
The sin(∠C) = opposite/hypotenuse
= |AB| / |AC|
= 12/20
= 3/5
= 0.6
so the answer is 0.6

It take 6 Pounds of flour to make 36 cakes. How much flour is needed to make 9 cakes?
Answer:
54 pounds
Step-by-step explanation:
To find out how much flour is needed to make 9 cakes, we first need to find out how much much flour is needed to make 1 cake. For that, we need to divide 6 by 36. That will give you 6. Now that we know how much flour is needed to make 1 cake, we will just have to multiply 6 by 9 to find out how much flour is needed to make 9 cakes. That will give you 54 pounds, which is your final answer.

Step-by-step explanation:
Choose all lengths that are equal to 6 feet 12 inches
A 3 yd 1 ft
B 7 ft
C 7 ft 2 in.
D 2 yd 1 ft
E 1yd 4 ft
The only length that is equal to 6 feet 12 inches is 7 ft.
What is unit of measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
To compare lengths, we need to convert all of them to the same units. One way to do this is to convert everything to inches.
6 feet 12 inches is equal to 6 x 12 + 12 = 84 inches.
3 yd 1 ft = 3 x 3 x 12 + 1 x 12 = 109 inches, which is not equal to 84 inches.
7 ft = 7 x 12 = 84 inches, which is equal to 6 feet 12 inches.
7 ft 2 in. = 7 x 12 + 2 = 86 inches, which is not equal to 84 inches.
2 yd 1 ft = 2 x 3 x 12 + 1 x 12 = 78 inches, which is not equal to 84 inches.
1yd 4 ft = 1 x 3 x 12 + 4 x 12 = 60 inches, which is not equal to 84 inches.
Therefore, the only length that is equal to 6 feet 12 inches is 7 ft.

Answer:
[text] x = p(m - n) [/tex]
Or
[text] x = pm - pn [/tex]
Step-by-step explanation:
Given:
[text] m = n + \frac{x}{p} [/tex]
Required:
Make x the subject of the formula
Solution:
What we are required to do is to rewrite the equation so that x will be alone on one side while the other variables will be on the other side.
[text] m = n + \frac{x}{p} [/tex]
Subtract n from each side
[text] m - n = n + \frac{x}{p} - n [/tex]
[text] m - n = \frac{x}{p} [/tex]
Multiply both sides by p
[text] p(m - n) = \frac{x}{p}*p [/tex]
[text] p(m - n) = x [/tex]

Answer:
B. 5x + 12.
Step-by-step explanation:
[tex]4 + x + x + 2x + 5 + 3 + x = ?[/tex]
Whenever you see variables without a visible coefficient, imagine there is a '1' in front of the variable.
[tex]4 +(1)x+(1)x+2x+5+3+(1)x=?[/tex]
From here, you can combine like terms.
Remember, combine means to add.
Like terms are terms whose variables (such as x or y) with any exponents are the same (such as x² or y²).
[tex](1)x+(1)x+2x+(1)x=5x.[/tex]
[tex]4+5+3=12.[/tex]
[tex]4+(1)x+(1)x+2x+5+3+(1)x=5x+12.[/tex]
I, therefore believe 5x + 12 is equal to 4 + x + x + 2x + 5 + 3 + x.

What is the largest 4- digit number that is divisible by 3, 6, and 9? Explain how you know.
========================================================
Explanation:
Start with the largest four digit number possible (9999) and see if it's divisible by 3, 6 and 9
9999/3 = 33339999/6 = 1666.59999/9 = 1111When dividing the number over 6, we don't get a whole number. So 6 is not a factor of 9999, and we cross 9999 off the list.
------------------------
Decrease the number by 9. We do this because the result will be another multiple of 9 (which is automatically also a multiple of 3 as well, since 9 = 3*3)
So we go from 9999 to 9990
Repeat the last set of steps we did earlier
9990/3 = 33309990/6 = 16659990/9 = 1110Every result is a whole number, which shows that 9990 is a multiple of 3, 6 and 9. In other words, 9990 is divisible by 3, 6 and 9. It's the largest such 4 digit number.

PREVIOUS
Answer:
D) 20%-24%
Step-by-step explanation:
The margin of error is ±2%, which means that the true proportion it can be 2% above the average proportion or 2% below the average proportion. Therefore, the percentage of students that might actually ride their bikes to school is 20%-24%.
Answer: A. 22%-24%
Step-by-step explanation: There's a +2% error range, so you just add 2% to the existing percentage to get your range of 22% (the original percentage) through 24% (the percentage you get after adding 2%)

Step-by-step explanation:
9+12+15= 36
[tex] 3\sqrt[?]]{?} 36[/tex]
The perimeters of the squares are 36 units, 48 units and 60 units respectively.

The line that is parallel to line CD in the figure is A. Line FA
From the provided information, line FA is the same distance from line CD at every point, meaning that these lines are parallel.
What do parallel lines mean?Parallel lines are lines on a flat surface that never meet or cross each other.
When two lines are straight from beginning to end, they are parallel. Their distance is always the same at all points.

Why is this false:
If the national economy shrank at an annual rate of 9% per year for three consecutive years, then the economy shrank by 27% over the 3-year period.
Answer:
It is false that, if the national economy shrank at an annual rate of 9% per year for three consecutive years then the economy shrank by 27% over the 3-year period, because this percentage does not follow a linear path, but on the contrary, it is calculated exponentially: 9% of each year is calculated on the rest that remained after discounting 9% the previous year.
Thus, if the national economy has a value of 100, after three years it will not have a value of 79, but a value of 75.35, as it arises from the following calculation:
100 x 0.91 ^ 3 = X
100 x 0.753571 = X
75.35 = X
