Answer:
78.
Step-by-step explanation:
the reason this is 78 is because you divide 6 by two then get 3. 3*20=60. 30% of 20 is 6. 6*3 is 18 plus 60=78
Its C because u have to divide 425 by 50 to get the mpg. Then because the truck now has an 80 gallon tank u have to multiply 8.5 with 80
If Ian uses 1/20 of the ketchup 4 times, this is equal to 4/20, or

.

can be simplified to

, which means we need to work out

of 12.2

is equivalent to 20%, which as a decimal is 0.2
0.2 x 12.2 = 2.44 - however, this is how much he has
used, and we need to figure out how much is left.
12.2 - 2.44 = 9.76
So, Ian has 9.76 oz remaining :)
Answer:
Option B) The area to the right of 35.5
Step-by-step explanation:
Data:
Let the probability of the correct answers be denoted by the letter C.
The probability of no more than 35 defective CD's can be 35 or less. Therefore, it is presented as follows:
P ≤ 35
Let, the probability of more than 44 correct answers can be presented like this:
P > 44
Therefore, combining the two inequalities gives an area at the right of 35.5
Answer:
Alice reaches 11 metres below the centre as lowest height.
