6 blue slabs have a mean weight of 7 kg. 3 yellow slabs have a mean weight of 5 kg. 1 grey slab has a mean weight of 9kg. work out the mean of 10 slabs
Answer: 6.6kg
Step-by-step explanation:
6 blue slabs have a mean weight of 7 kg. The total weight of the 6 blue slabs will be:
= 6 × 7kg
= 42 kg
3 yellow slabs have a mean weight of 5 kg. The total weight of the 3 yellow slabs will be:
= 3 × 5kg
= 15kg
1 grey slab has a mean weight of 9kg.
To get the mean of the 10 slabs, we add their total weights together and divide by 10. This will be:
= (42kg + 15kg + 9kg)/10
= 66kg/10
= 6.6kg
Based on the information given the mean of 10 slabs is 6.6 kg.
Formulate
(9+5×3+6×7)/10
Calculate the quotient
9+15+6×7/10
9+15+42/10
Calculate the sum or difference
24+42/10
66/10
Reduce the fraction
33/5
Hence:
Mean=6.6 kg
Inconclusion the mean of 10 slabs is 6.6 kg.

A biker cycles 9 miles in 2/3 of an hour.
a
Make a chart and fill it in to show how far he will bike if he maintains the same pace for 2 hours, 3 hours, 3.5 hours
Answer:
2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles
Step-by-step explanation:
1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)
2.) 2 hours: 13.5 * 2 = 27 miles
3.) 3 hours: 13.5 * 3 = 40.5 miles
4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles
He rides 27 miles in two hours, 81/2 miles in 3 hours, and 189/4 in 3.5 hours.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, A biker cycles 9 miles in 2/3 of an hour.
∴ He rides (9×3/2) is (2/3)×(3/2) hours.
He rides 27/2 miles in 1 hour.
So, He rides (27/2)×2 in 2 hours.
27 miles in 2 hours.
He rides (27/2)×3 miles in 3 hours.
81/2 miles in 3 hours.
He rides (27/2)×(7/2) miles in 7/2 hours.
189/4 miles in 7/2 hours.
