Answer:
1/2 of his book
Step-by-step explanation:
1/3 of an hour = 1/6 of the book
3/3 of an hour = 3/6 or 1/2 of the book read
Answer:
Step-by-step explanation:
For this division we can first use factoring of the numerator, then eliminate the common factors.
Factoring the numerator by the term grouping method
removed terms
WXYZ is a rhombus with vertices W(0,4b), X(2a,0), Y(0,-4), Z(-2,0). You can see thap points W and Y lie on the y-axis and points X and Z lie on the x-axis. Then the centre of the rhombus is origin, thus W and Y are symmetric about the origin. Then b=1 and point W has coordinates (0,4). Similarly points X and Z are symmetric about the origin and a=1, hence X(2,0).
Let KLMN be middlepoints of segments WX, XY, YZ, ZW, respectively. Then
.
Now find the vectors
,
,
and
:
that means that
.
Similarly,

,
.
You prove that KLMN is a recctangle.

Answer:
(8, 20)
Step-by-step explanation:
<u>Function given:</u>
<u>Let's try the given options:</u>
<u>(0, 18)</u>
<u>(5, 19.5)</u>
- 19.5 = 16+0.5*5
- 19.5 = 16+2.5
- 19.5 ≠ 18.5
- No
<u>(8, 20)</u>
- 20 = 16 + 0.5*8
- 20 = 16 + 4
- 20= 20
- Yes
<u>(10, 21,5)</u>
- 21.5 = 16 + 0.5*10
- 21.5 = 16 + 5
- 21.5 ≠ 21
- No
