It might be 2/9 sorry if it wasn’t
R=12.13
A=pi×r²
A=pi×12.13²
A≈462.2442041
A≈462.2 (to the nearest tenth).
So the answer is A≈462.2.
Answer:
≈9.64 gallons
Step-by-step explanation:
To solve, we can figure out how many quarts are in a minute and use that to figure out how many quarts are in an hour. Then, we can convert quarts to gallons.
4.5 quarts = 7 minutes
First, we can find how many quarts equal 1 minute. To do this, we can divide both sides by 7 because anything divided by itself equals 1
4.5/7 quarts = 1 minute
Next, we want to figure out how many quarts go into 60 minutes, or 1 hour. To do this, we can multiply both sides by 60 because 1 * 60 = 60
4.5 * 60 / 7 quarts = 60 minutes = 1 hour
We now know how many quarts are in an hour, so we can now convert quarts to gallons
4 quarts = 1 gallon
divide both sides by 4
1 quart = 1/4 gallons
To get from quarts to gallons, we can divide by 4, so we have
(4.5 * 60 / 7)/4 = 4.5 * 60 / 28
≈9.64 gallons
Answer:
y = -1/5x + 19/5 or
x + 5y = 19.
Step-by-step explanation:
The slope of the line (m) = (5-3) / (-6-4)
= -1/5.
Using the point-slope form of the equation of a line:
y - y1 = m(x - x1) m = -1/5. x1 = 4 and y1 = 3 , so:
y - 3 = -1/5(x - 4)
y - 3 = -1/5x + 4/5
y = -1/5x + 19/5 which is the equation in slope-intercept form.
Converting to standard form ( multiplying by 5):
5y = -x + 19
x + 5y = 19.
Answer:
A.
Step-by-step explanation:
3x + x - 13 + 4 - 6x = 12
we try to combine the elements with the same power of x (including the ones without any x) :
3x + x - 6x
-13 + 4
so, we get
-2x - 9 = 12
-2x = 21
x = -21/2
