60 mL = 60/1000 L
= 0.06 L
1 container of resin = 0.06L
19 containers of resin = 0.06 x 19
= 1.14 L
1.14 L of hardener should be added to 19 containers of resin.

The volume of water in the pipes is:
Step-by-step explanation:
To identify the volume of a cylinder, the formula is usually used:
- <u>Cylinder volume = PI * radius of the circular flat face squared * height of the cylinder.
</u>
We will start with the calculation of the largest cylinder:
- Largest cylinder volume = PI * (7.5 cm)^2 * 90 cm (remember that the radius is the distance from the edge of the circle to the middle of the circle, so the radius is not the 15 cm shown by the image but 7.5 cm)
- Largest cylinder volume = 15904.31 cm^3
Since the two lateral cylinders are the same size, only one calculation will be made and at the end, it will be multiplied by two:
- Small cylinder volume = PI * (5cm)^2 * 7cm
- Small cylinder volume = 549.78 cm^3
Multiplying the result by two to obtain the volume of the two cylinders:
- Small cylinder volume = 549.78 cm^3 * 2 = 1099.56 cm^3
Finally, to obtain the total volume of the entire fire hydrant, the calculated volumes are added:
- T<u>otal volume of water = 15904.31 cm^3 + 1099.56 cm^3 = 17003.87 cm^3</u>
Answer:
Step-by-step explanation:
If 42 is 60%, let's find what 10% would be. 42 divided by 6 = 7. 10% would be 7 kids. now, we can do 7*4 because on the small bus is 40% of kids. 7*4=28 kids. 28 + 42 = 70 kids. you could have also done 7*10 for this answer because of the 7 = 10% and we want the 100%
