Answer:
52 km/hr
Step-by-step explanation:
Speed equals distance over time.
2 hours 45 minutes = 2.75 hours
S = 143/2.75
S = 52
The car’s speed is 52 kilometers per hour.
Answer:
a) 1/10
b) 110
Step-by-step explanation:
A) we start by getting the total number of rolls
That would be;
11 + 22 + 7 + 8 + 13 + 19 = 80
The frequency of getting a 4 is 8
The probability that the next roll will be a 4 is;
8/80 = 1/10
b) Firstly, we get the probability of getting a 2
We have this as:
22/80
So for 400 rolls, the number of 2’s will be;
22/80 * 400
= 22 * 5 = 110
The answer is C
negative times negative is equals to positive
Given:
Length = 3x + 6y cm
Area = 3x² + 9xy + 6y²
Because Area = Width * Length, therefore
Width = Area/Length
= (3x² + 9xy + 6y²)/(3x + 6y).
Width =


Answer:
x+y
It would be 539.666 but if you round up 540
