Answer:
16
Step-by-step explanation:
since 4/5 have a pet, you would divide by 5.
30÷5=6
but since only 4 have a pet, you would multiply that by 4 to get 4/5
6×4=24
24 students have pets
now you would divide by 3, as 2/3 have a dog
24÷3=8
but only 2/3 have dog, so you would multiply by 2
8×2=16
I'm sure there is a simpler way but this is how I would do it.
Answer:
B. 1 over 8
Step-by-step explanation:
To determine the probability of the spinner landing on 5, we need to first know what probability is,
probability = required outcome/all possible outcome
since the spinner is divided into 8 equal sections and each section contains number from 1-8, this implies there are total of 64 numbers on the spinner. This implies that all possible outcome = 64
In each section there is 5, since there are 8 sections on the spinner, the number of 5's on the spinner are 8.
This implies that the required outcome = 8
but
probability = required outcome/all possible outcome
probability (of the spinner landing on 5) = 8/64 =1/8
It's 25 units :) I recommend desmos graphing calculator for these types of problems good luck
Answer:
40 km/h
Step-by-step explanation:
rate of change of distance = speed
speed = distance/time
speed = (400 km)/(10 h)
speed = 40 km/h
The answer is A) 36. Hope I was able to help
