We need to follow PEMDAS.
We need to do the division before we can do the subtract (which becomes into addition because of the signs).
12 - 16/-4
12 - (-4)
12 + 4
16
Your final answer is C. 16.
Answer: Jill got the larger smoothie and its volume is 1609.14 cubic cm.
Step-by-step explanation:
Since we have given that
Jill purchased the cylindrical container.
Height of container = 8 cm
Radius = 8 cm
So, volume of cylindrical container would be

Marcy purchased the rectangular container.
Height of container = 8 cm
Width = 8 cm
Length = 8 cm
so, volume of rectangular container would be

Hence, Jill got the larger smoothie and its volume is 1609.14 cubic cm.
You could use many methods to find the answer to this problem, but I am going to use the most efficient one I know.
18f+15(4f)=156
F is for fins. We should now solve the equation.
18f+60f=156
78f=156
156÷78=2
So fins cost 2 dollars. Now, we know snorkels cost four times the amount of fins. Four times 2 is eight. So the snorkels cost $8 to rent. Let's check our math.
15(8) + 18(2)
120+36=156
So it cost $8 to rent a snorkel.
Answer:
There are 80 marks in total.
Step-by-step explanation:
Let the number of total marks be
.
The percentage score of the student can be written as the ratio
.
However,
.
Equating the two:
.
Cross-multiply (that is: multiple both sides by
, the product of the two denominators) to get
.
.
In other words, there are 80 marks in total.
