Answer:
Nina will finish first.
Step-by-step explanation:
Let's c<u>alculate how many pages each person reads in one day</u>:
- Jayson ⇒ 48 pages / 3 days = 16 pages/day
- Marcus ⇒ 50 pages / 4 days = 12.5 pages/day
- Nina ⇒ 120 pages / 5 days = 24 pages/day
Then we <u>divide the number of pages of each book by reading speed of the respective person</u>:
- Jayson ⇒ 480 pages ÷ 16 pages/day = 30 days
- Marcus ⇒ 400 pages ÷ 12.5 pages/day = 32 days
- Nina ⇒ 600 pages ÷ 24 pages/day = 25 days
Thus Nina will take the shortest time finishing her book.
<h3>a) Never</h3>
{All angles of a rectangle are right}
<h3>b) Always</h3>
{all sides of a rhombus are the same, 4×13=52}
<h3>c) Always</h3>
{oposite angles of a paralleogram are congruent}
<h3>d) Never</h3>
{parallel sides has the same slope}
<h3>e) Always</h3>
{square has all sides of the same length, so it is rhombus}
<h3>f) Sometimes</h3>
{Only if it has angles of 90°}
Answer:
$14.64
Multiply 8 by .67 which is 5.36
Subtract 5.36 from 20.00 and that's 14.64
Hmm the closes one i could get is C Because it's the only one near 4,125
Hope that help :D
Answer:
8.4
Step-by-step explanation:
The diagonals of a rectangle are equal.
That means WY = XZ
16x+2 = 36x-6
Subtract 16x from each side.
16x -16x+2 = 36x-16x-6
2 = 20x -6
Add 6 to each side
2+6 = 20x-6+6
8 = 20x
Divide by 20
8/20 = 20x/20
2/5 =x
We want to find the length of the diagonal
WY = 16 ( 2/5) +2
Changing to decimal form
WY =16 * .4 +2
WY =6.4+2
= 8.4
