Answer:
56
Step-by-step explanation:
Hello!
If Nia is three years older than half of Jordan's age, we must divide Jordan's age by 2 (to find half of his age).
Jordan is eight years old:
8 divided by 2 equals 4
4 years old is half of Jordan's age. Now, to find Nia's age, we must add 3 to half of Jordan's age (4).
4+3= 7
Nia is 7 years old.
I hope this helps answer your question! Have a great day!
Answer:
222 fence posts
Step-by-step explanation:
Since the log is 20 m long, correct to the nearest metre and has to be cut into fence posts which must be 90 cm long, correct to the nearest 10 centimetres, there can be x fence posts 90 cm long.
So, we have x × 90 cm = 20 m
x × 0.9 m = 20 m
x = 20 m/0.9 m
x = 222.22
x ≅ 222 fence posts
So, the largest number of fence posts that can possibly be cut from the log is 222 fence posts.
Find the mean of <br>35,26,31,16,21,23,27,30,26,17,19,27

Hello!
To find the mean, we must add all the terms in the dataset and divide by how many there are.
35+26+31+16+21+23+27+30+26+17+19+27=450
There are 12 terms in the dataset, so we divide by 12:
37.5
So the mean of this set is 37.5.
Hope this helps you!
