Answer:
Step-by-step explanation:
Ratios can be of 2 types here:
Part to Part
and
Part to Whole
Part-to-Part ratios give the relationship between 2 distinct things/groups. Such as the ratio of male to female in a class, or ratio of water to sugar in a drink etc.
Part-to-Whole ratios give the relationship between one group/thing to the whole population. Such as the ratio of male to total students in a class, or the ratio of cups of sugar to total cups of drinks etc.
<u>Note:</u> If there are 2 parts in a population, we can essentially write 3 ratios. For example, the ratio of male to female in a class is 4 to 5. So in total there are 4+5 = 9 parts (whole). So we can say:
ratio of male to total population is 4 to 9
ratio of female to total population is 5 to 9
Also,
ratio of male to female (as stated before) is 4 to 5
3 ratios.
Answer:
(b) For each hour that Michelle drove, she traveled an additional 50 miles.
Step-by-step explanation:
Given
---- start
--- end
Required
Which is true
(a): Journey = 6 hours
This is false, because:


---- 7 hours
(b): The average rate is 50 miles per hour
To do this, we calculate the slope (m) using:




This means that the rate is 50 miles driven in 1 hour.
<em>(b) is correct</em>
<em></em>
<em>Others are incorrect</em>
Answer:
8mi
Step-by-step explanation:
Using Pythagoras theorem
Hypotenuse square = opposite square + adjacent square.
Let the other leg be x
10 square = 6 square + x square
100 = 36 + x square
Collect like terms
X square = 100 -36
X square = 64
Find square root of both sides
X = square root of 64
X =8mi
