40 lawns
 because she's getting paid $15 per lawn and she mowed enough to earn $600 so you would divide 600 by 15 and get 40

Answer:  Ella has to mow 40 lawns.

Step-by-step explanation:  Given that Ella mows lawns in her neighborhood during the summer and gets paid $15 per lawn.

We are to find the number of lawns that she has to mow to earn her goal amount of $600.

Let n represents the required number of lawns.

Then, according to the given information, we have

15\timex n=600\\\\\Rightarrow n=\dfrac{600}{15}\\\\\Rightarrow n=40.

Thus, Ella has to mow 40 lawns.

The height of the enlarged picture will be 20 in because 15 divided by 6 is 2.5 so you multiply 2.5 by 8 in and you get 20.

100 POINTS AND BRAINLIEST. I need help ASAP.
Svetach [21]

Answer:

Step-by-step explanation:

First what we must do is rewrite the table to find a solution:

0.25^x −0.75x+1

   64     3.25

   16     2.5

    4      1.75

    1      1

 0.25     0.25

 0.0625 −0.5  

 0.015625  −1.25

We see where the values of the function are the same:

x = 0 (1)

x = 1 (0.25)

answer:

x = 0

x = 1

SHALL GIVE BRAINLIEST ANSWER!! A ​40% solution of fertilizer is to be mixed with an ​80% solution of fertilizer in order to get
sdas [7]

Answer:

20 gallons of the 40% solution, 60 gallons of the 80% solution

Step-by-step explanation:

Let x = the gallons of the 40% solution, and y = the gallons of a 80% solution. The first thing we want to do here is to convert each percentage into decimal form - including the ​70% solution mixture.

40% = 0.40,

80% = 0.80, respectively 70% = 0.70

As you can tell, 0.40 is associated with x gallons, 0.80 is associated with y gallons, and the mixture contains 0.70 * 80 solution, as 0.70 is associated with 80. Therefore we can formulate the following expression,

0.40x + 0.80y = 0.70 * 80

At the same time x + y = 80, as the solution ( mixture ) is present with 80 gallons. Isolating x, x = 80 - y. Let us plug that into our expression, solving for y, following by x gallons.

0.40\left(\:80\:-\:y\:\right)\:+\:0.80y\:=\:0.70\:\cdot \:80

0.4\left(80-y\right)+0.8y=56 ( Multiply either side by 10 )

4\left(80-y\right)+8y=560 ( Expand )

320-4y+8y=560

320+4y=560

4y=240

y = \frac{240}{4} = 60 ( Substitute to solve for x )

x = 80 - y = 80 - 60 = 20

As you can see there are 20 gallons of the 40% solution, and 60 gallons of the 80% solution.
