3x4 =12 (this is the square)
1.5 x 1.5 x 3.14= 7.065 however since it is a half of circle we divide 7.065 by 2 = 3.5325
Now add 3.5325 and 12 = 15.5325 round it to 15.53 then multiply by $2
The answer is $31.06

How many ml of 20 percent acid should be added to pure acid to make 70 ml of 30 percent acid?
Novay_Z [31]

Answer:

61.25%

Step-by-step explanation:

How many ml of 20 percent acid should be added to pure acid

to make 70 ml of 30 percent acid?

:

let x = amt of 20% mixture

then

(70-x) = amt of pure acid

:

0.20x + (70-x) =0 .30(70)

0.20x + 70 - x = 21

= 21 - 70

-0.8x =-49

x = 61.25%

x = +61.25 ml of 20% stuff

You can use a Scatter Plot to show the relationship between two sets of data. As you can see, this Scatter Plot shows the Speed in meters per second (m/s) versus the Distance in meters (m).
 
 In the figure attached, the first point is (2,5), you need to move 2 on the axis "speed (m/s)" and 5 on the axis "distance (m)". This means that the first point is the intersection between 2 m/s and 5 m. The second point is (3,8), then, you need to move 3 on the axis "speed (m/s)" an 8 on the axis "distance (m)" You must do this with the other values.
