Answer:
A: 336 km
B: 14 L
Step-by-step explanation:
Use a proportion
210 km / 5 L = x / 8L Cross multiply
8*210 = 5 x
1680 = 5x
x = 1680 / 5
x = 336 km
===============
210 /5 = 588/x Cross multiply
210x = 588 * 5
210x = 2940 Divide by 210
x = 2940/210
x = 14 L
Answer:
Problem 1. <em>(19/2)b + 15</em>
Problem 2. <em>3/16</em>
Step-by-step explanation:
Question number 1
5/8 (16b+24) -1/2b =
= (5/8) * (16/1) * b + (5/8) * 24 - (1/2)b
= 10b + 15 - (1/2)b
= (20/2)b - (1/2)b + 15
= (19/2)b + 15
Question number 2
3/4 (16/64 + 12a) -9a =
= (3/4) * (16/64) + (3/4) * 12a - 9a
= (3 * 16)(4 * 64) + (3/4) * (12/1) * a - 9a
= (3 * 1)(4 * 4) + (3 * 12)/(4 * 1) * a - 9a
= 3/16 + (3 * 3)/(1 * 1) * a - 9a
= 3/16 + 9a - 9a
= 3/16

The number of people whose hobby is reading but not riding a motorcycle is 5.
<h3>What is the relative frequency of not riding a motorcycle?</h3>
We want to calculate the number of people whose hobby is reading but they don't like riding the motorcycle,
therefore, when we look into the table we will find out that block A2 is the block that represents the number of people whose hobby is reading but not riding a motorcycle.
Hence, the number of people whose hobby is reading but not riding a motorcycle is 5.
