Answer:
p = 17.125
Step-by-step explanation:
I think the answer is A.
the formula to find the volume of a sphere is 4/3 x pi x radius cubed. this means you have to split the diameter in half giving you 3.7 which automatically rules out the answers with 7.4 written in them. now you have to compare A and D but D has 3/3 at the end. this is where you can see that it’s wrong because when you cube you don’t use a fraction.
X is the independent variable (think 'input variable'); all of the values of x which are valid (ones that don't create division by zero or square root of a negative value) is the domain.
Answer:
18 kilometres
Step-by-step explanation:
Speed of the car is 72 kilometres per hour
means the car runs 72 kilometers within 60 minutes
so, the car will travel in 15 mins,
72×15/60
= 72/4 = 18 kilometres
48- because you multiply 2 sides together then multiply the other 2 sides then add those together to get 48 so 5x4=20 and 4x7=28 < 28+20=48
