edy baked three cakes with different masses in the ratio of 7:5:4. The mass of the lightest cake is 800g. Find the mass,in g, of the heaviest cake 7:5:4​

Answers

Answer 1
let 4units represent 800g, since the ratio of the masses is 7:5:4, with 800g being the lightest.

1 unit = 800/4 = 200g
hence, the mass of the heaviest cake will be 7 units, which is 7 x 200g = 1400g

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

Answers

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.

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

Answers

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.
