Answer:
First, we know that:
1 1/3 = 4/3
10 2/3 = 32/3
15 minutes = 0.25 hours
Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.
From the information, we can tell that:
Lee can type:
4/3 pages in 0.25 hours
32/4 pages in x hours
So x should be:
x = (32/4 . 0.25)/4/3 = 2 (hours)
So it takes Lee 2 hours ro type 10 2/3 pages
Here, we are required to provide a diagram showing the relative positions of the five runners with respect to one another.
- According to the inference drawn from the diagram attached, Nadine is ahead in the race.
The premises in the question are as follows:
- Meg is 20 meters behind Edith as implied in the attached image
- Edith is 50 meters ahead of Wanda as implied in the attached image
- Wanda is 20 meters behind Olivia as implied in the attached image
- Olivia is 40 meters behind Nadine as implied in the attached image.
The image attached contains the diagram representing the distance between the runners in the race.

Answer:
x = 24
Step-by-step explanation:
Apply Pythagoras theorem:
Answer:
b)0, yes
Step-by-step explanation:
Given:
Vectors (4,8) . (6,-3)
Finding inner product of vectors:
= 4x6 + 8x-3
=24-24
=0
Now to check the angle between them using formula a.b=|a|.|b|cosθ
|a|=
=8.9
|b|=
=6.7
Putting values of a.b=0 and |a|=8.9, |b|=6.7 in a.b=|a|.|b|cosθ we get,
0= 8.9(6.7)cosθ
cosθ =0
θ=90 degrees
Hence the two vectors are perpendicular !
