Marsha created this scale drawing of a soccer field, using a scale factor of 1 inch: 12 yards. She wants to make another scale m
odel of the same soccer field, using a scale factor of 1 inch: 36 yards. Find the length and width of the new scale drawing. a 1.33 inches, 2 inches. b 3 inches, 2 inches c 4 inches, 6 inches d 27 inches, 18 inches

Answer:
b 3 inches, 2 inches
Step-by-step explanation:
In the figure attached, the complete question is shown.
Originally the scale is 1 inch: 12 yards, the width is 6 inches, that is, 6*12 = 72 yards, and the length is 9 yards, that is, 9*12 = 108 yards
If the scale is 1 inch: 36 yards, then 72 yards are:
1 inch / x inches = 36 yards / 72 yards
x = 72/36 = 2 inches
which represents the new width.
And 108 yards are:
1 inch / x inches = 36 yards / 108 yards
x = 108/36 = 3 inches
which represents the new length.

Answer:
Step-by-step explanation:
We essentially need to solve for l; in other words, we must isolate it to one side.
First, notice that the term doesn't have any l terms in it, so we can just move this to the left side by subtracting both sides by
:
A - = 2lw
Now, the right side has 2lw, so we must divide both sides by 2w to isolate l:

Answer:
33 gallons of water to begin with.
Step-by-step explanation:
So we essentially are given two coordinates: (6,87) and (21,222). To find an equation, we simply need to find the slope and y-intercept. We know it's a linear equation because it's a steady stream, meaning a constant slope.
The slope is:
So, the rate at which the stream flows is 9 gallons per minute.
Now, let's find the initial amount of water. To do this, we can use point-slope form. Pick either of the two points. I'm going to use (6,87).
So, there were 33 gallons of water in the tank to begin with.
