$45 ÷ 2=22.5 22.5 + 5 free hours = 27.5 hours total. You have to divide the amount of money you have by the $2 per hour and then you add the 5 free hours.

Fractions: three oil tankers together contain 37 5/7 litres of oil. If two tankers have 11 3/14 litres and 12 3/7 litres of oil.
ale4655 [162]

Step-by-step explanation:

It is given that, three oil tankers together contain 37 5/7 litres of oil.

Total volume of oil is \dfrac{264}{7}\ L

If two tankers have 11 3/14 litres and 12 3/7 litres of oil.

Oil in first tanker is \dfrac{157}{14}\ L

Oil in second tanker is \dfrac{87}{7}\ L

Oil in first and second tanker is :

\dfrac{157}{14}\ L+\dfrac{87}{7}\ L=\dfrac{331}{14}\ L

Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )

=\dfrac{264}{7}\ L-\dfrac{331}{14}\ L\\\\=\dfrac{197}{14}\ L

Hence, this is the required solution.

drek231 [11]

Answer:

0.225

Step-by-step explanation:

Total outcomes of choosing 5 out of 18 members = 18C5

Outcomes of choosing 2 out 11 favourers, 3 out of 7 members  =          11C2 & 7C3

Probability = Favourable outcomes / Total outcomes

= ( 11C2 x 7C3 ) / 18C5

<u>[ { 11 ! / 2! 9! } {7 ! / 3! 4! } ] </u>

       [ 18 ! / 5! 13! ]

( 55 x 35 ) /  8568

1925 / 8568

= 0.2246 ≈ 0.225

Find the value of x.
nadya68 [22]

Answer:

127 degrees

Step-by-step explanation:

1. Find the angle next to "x" using the fact that all the angles in a triangle add to 180 degrees.

180-30-97 = 53

2. Angle X and the angle that is 53 degrees are supplementary meaning they will add to 180 degrees since it's on a line

180-53=57

Hope this helped :)
