Answer:
8 hours
Step-by-step explanation:
basic equation
Q (flow rate) = V (volume)/ t (time)
so to find the time we just rearrange the equation and become
t = V/Q
V of cylinder
V = πr²T
and r (radius) = ½ diameter
V = 3.14 x 5² x 1.4
V = 109.9 m³
if the Q is 13 m³/hour then
t = 109.9/13 = 8.453 hours
round to nearest hour = 8 hours
<span>127.3 feet
This problem requires the use of pythagoras theorem. Ignore the face that it's a baseball diamond. All you're concerned with is that you have a square that's 90 feet per side and you want to know what the length of the diagonal. So you have a right triangle with 2 sides of 90 feet each and you want to know the length of the hypotenuse.
The formula is
C^2 = A^2 + B^2
Both A and B are 90, so plugging them into the formula gives
C^2 = 90^2 + 90^2 = 8100 + 8100 = 16200
So
C^2 = 16200
Take the square root of both sides
C = 127.2792
Round to the nearest tenth, giving
C = 127.3</span>
Answer:
Step-by-step explanation:
Okay This is what is happening...
$955 total - $435 painting= $520 doll profit
First, subtract the painting Danika sold from the total. This will give you the amount she earned from the doll collection. Then, divide by the dollar amount to give the amount of dolls sold.
$520 doll profit divided by $20 = $26 fir each doll
or
Equation: 955=435-20d
Variable: d= number of dolls sold
Solve Equation: 955=435-20d
-435=-435
955-435=435-435-20d
520=20d
/20=/20 (I used "/" as my divide sign you can use the other one)
520/20=20/20
26=d
Final Answer: 26=dolls sold
Answer:
The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
