tienes que usar la fórmula de: pi por radio al cuadrado
Answer:
[tex]314in^{2}[/tex]
Step-by-step explanation:
Circumference is [tex]2\pi r[/tex]
Find your radius
[tex]2\pi r=62.8\\\pi r=31.4\\[/tex]
Let [tex]\pi =3.14[/tex] for simplicity
r=[tex]\frac{31.4}{3.14}[/tex]=10
Now use the equation for the area of a circle to find the area of the clock face.
Area of a circle is [tex]\pi r^{2}[/tex]
Area of clock face is [tex]\pi (10^{2} )[/tex]
=[tex]100\pi[/tex]

if f(x)=3x-1 and g(x)=x+2,find (f+g)(x)
Answer:
(f + g)(x) = 4x + 1
Step-by-step explanation:
Given f(x) = 3x - 1 and g(x) = x + 2, find (f + g)(x):
We can rewrite (f + g)(x) as f(x) + g(x), and solve the composite functions through addition:
f(x) + g(x) = (3x - 1) + (x + 2)
Combine like terms:
f(x) + g(x) = 3x + x + 2 - 1 = 4x + 1
Therefore, (f + g)(x) = 4x + 1.

Determine the mystery decimal number from the clues listed.
Clue 1: between 2/5 and 3/5
Clue 2: greater than 1/2
Clue 3: a multiple of 0.11
Answer:
.55
Step-by-step explanation:
3/5 = 0.6
1/2 = 0.5
it has to be in between these two numbers
5 x 0.11 = 0.55
Answer:
Step-by-step explanation:
It is between 0.4 and 0.6
It is greater than 1/2. That means that the starting point is 0.5 to 0.6
The final clue should nail it. It is a multiple of 0.11. That means it is 0.55. One possible answer is 11/20

3 plus four times a number.
Answer:
3 + 4x
Step-by-step explanation:
Let "a number" be x.
Therefore "four times a number" is 4 multiplied by x which is 4x.
Now add 3 for "3 plus".
3 + 4x
Answer:
Our equation would be: 3 + 4x.
Let's say x=8
That would now make our equation:
3 + 4(8) =
Step-by-step explanation:
But let's solve this equation :)
First, we would add 3+4, to get 7.
Then, we would multiply the 7 by 8.
Lastly, we know 7 x 8 = 56
So, 3+4(8)= 56
But we could also create a function statement out of this.
Our statement for this equation would be:
When x equals 8 the answer or in algebraic terms the "output" is 56.

Answer:
-32
Step-by-step explanation:
if we multiply - 2 and -6 it becomes positive so it will be 12.
-2 multiply 22 will be -44
12 - 44 is -32.
answer : -32
you distribute so you do -2 times -6 which is 12. then -2 times 22 which is -44.
you end up with 12 - 44, which equals -32.

5. Gardener Gary planted 21 rows of tomatoes
and squash. He planted twice as many rows of
tomatoes as rows of squash. How many tomato
plants were planted if there are 12 plants per
row?
Answer:
168
Step-by-step explanation:
first find out how many rows of squash there are
21 = x + 2x
21 = 3x
7 = x
then find out how many rows of tomatoes there are
7 × 2 = 14
if there are 12 plants per row, we can multiply
14 × 12 = 168
Gardener Gary planted 168 tomato plants
How to determine the number of yellow leaves?Let the rows of tomato be x and the rows of squash be y.
So, we have:
x + y = 21
The statement twice as many rows of tomatoes as rows of squash means that:
x = 2y
Substitute x = 2y in x + y = 21
2y + y = 21
This gives
3y = 21
Divide by 3
y = 7
Substitute y = 7 in x = 2y
x = 2 * 7
x = 14
This means that Gary planted 14 rows of tomato.
The number of tomato plants is then calculated using
Tomato plants= 14 * plants per row
This gives
Tomato plants = 14 * 12
Evaluate the product
Tomato plants = 168
Hence, Gardener Gary planted 168 tomato plants

What is the rule when you add a negative number and positive number?
Answer:
a negative plus positive equals a negative-
Answer:
"To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values. The result takes the sign of the integer with the larger absolute value. The sum of any integer and its opposite is equal to zero."
Step-by-step explanation:
Simpler Explanation: If you add a positive number with a negative number, the sign (negative/positive) of the sum is the same as the integer (number) with the largest absolute value. For example;
1. 10 + -12 = -2
Here, the sum has the same sign (negative) as the largest number in the equation (-12).
2. 7 + -3 = 4
Here, the sum has the sign (positive) as the largest number in the equation (7).
A large koi pond is filled from a garden hose at the rate of 12 gal/min. Initially, the pond contains 200 gal of water.
(a) Find a linear function V that models the volume of water in the pond at any time t.
(b) If the pond has a capacity of 1304 gal, how long does it take to completely fill the pond?
a) The linear function that models the amount of water after t minutes is given by:
[tex]V(t) = 200 + 12t[/tex]
b) It takes 92 minutes to completely fill the pond.
Item a:
Initially, the pond contains 200 gal of water, that is, the linear function has a y-intercept of 200.Filled at a rate of 12 gallons per minute, thus the linear function has a slope of 12.Then, the function is:
[tex]V(t) = 200 + 12t[/tex]
Item b:
It takes t minutes to fill the pond, t is found for which:
[tex]V(t) = 1304[/tex]
Then
[tex]200 + 12t = 1304[/tex]
[tex]12t = 1104[/tex]
[tex]t = \frac{1104}{12}[/tex]
[tex]t = 92[/tex]
It takes 92 minutes to completely fill the pond.
