A rectangular garden has dimensions of 100 feet by 10 feet. Next season, the garden is decreased to 2/5 of its size. What is the
mina [271]

Answer:

40 feet by 4 feet

Step-by-step explanation:

Given length (l) = 100 feet

width (w) = 10 feet

As mentioned in the question the size of garden is decreased to 2/5 of its size. <u>It will effect the length and width with the same proportion.</u>

So,

New length = 100 * 2/5 = 40 feet

New width  = 10 * 2/5 = 4 feet

Therefore, the scale of new drawing would be 40 feet by 4 feet

Solve The Following System of equations by graphing<br><br>3x + y = 5<br>x - 4y = 32​
Nostrana [21]

first you convert to slope intercept form

3x+y = 5 is the same as y = -3x+5

x - 4y = 32 is the same as y = 4x-8

then you graph

(starting with the y-intercepts as your first points)

the point where the two lines intercept is your solution.

The owner of the plant nursery where you work tells you to fill 350 milliliter bottles from a 30 liter drum of fertilizer. How m
valina [46]
So we know that there are 1000 mL in 1 L. We can set up an equation that allows us to solve for how many bottles are needed in order to empty the 30 L tank:

\frac{1 bottle}{350 mL}*  \frac{1000 mL}{1 L}* \frac{30 L}{1 tank}

This equation then allows us to cancel out the units of mL and L, leaving us with how many bottles are needed per tank. Then we multiply straight across to give us:

\frac{30,000}{350}= \frac{85.71 bottles}{1 tank}

The question asks us to round up to the next whole number, so it would take 86 bottles to empty one 30 L tank.
