Minchanka [31]

Answer: See explanation

Step-by-step explanation:

Total water fetched = 24 pints.

Jill drank a tenth of this. This will be:

= 1/10 × 24

= 2.4 pints

Jack drank a quarter. This will be:

= 1/4 × 24 = 6.

They gave three eighths to dame Dob . Thus will be:

= 3/8 × 24

= 9

They gave a fifth to jill's mother. This will be:

= 1/5 × 24.

= 4.80

Amount that'll be left over will be:

= 24 - (2.40 + 6 + 9 + 4.80)

= 24 - 22.2

= 1.8

1.8 pints of water will be left over.

il63 [147K]

Answer:

√254 feet

Step-by-step explanation:

This is basically a triangle, with a height of 2, and hypotenuse of 16.

Using the Pythagorean theorem (a^2+b^2=h^2) we can find the other side.  

2^2+b^2=16^2

4+b^2=256

b^2=254

b=√254

Write the standard equation for a circle with center (−6, −8), that passes through (0, 0)
chubhunter [2.5K]
Standard equation:  (x-h)^2 + (y-k)^2 = r^2

Here,                        (0-[-6])^2 + (0-[-8])^2 = r^2
Find r:                           36        +   64         = 100, so r = 10

Then the desired equation is (x+6)^2 + (y+8)^2 = 10^2
