- Point A = 3/10
- Point B = 2/5
- Point C = 9/10
- Point D = 7/10
====================================
Explanation:
Point A is located at 0.3; each tickmark represents 0.1
0.3 as a fraction is 3/10 because 3 is in the tenths decimal place. This doesn't reduce.
----
Point B is at 0.4 which converts to 4/10 and then that reduces to 2/5. Divide both parts of 4/10 by 2 to get to 2/5
----
Point C is at 0.9 which converts to 9/10. That's as simplified as that fraction gets.
----
Point D is at 0.7 so it becomes 7/10. That doesn't reduce either.
Answer:
The length of the shorter part of the wire is 24 centimeters.
Step-by-step explanation:
Let
the total length of the piece of wire, where
and
are the perimeters of the greater and lesser squares. All lengths are measured in centimeters. Since squares have four sides of equal length, the side lengths for the greater and lesser squares are
and
. From statement we find that the sum of the areas of the two squares (
), measured in square centimeters, is represented by the following expression:
(1)
And we expand this polynomial below:


(2)
If we know that
and
, then the length of the shorter part of the wire is:
By the Quadratic Formula, we determine the roots associated with the polynomial:
,
The length of the shorter part of the wire corresponds to the second root. Hence, the length of the shorter part of the wire is 24 centimeters.

Answer:
2nd Option is correct.
Step-by-step explanation:
Given:
Renata has $20 in gift card.
She bought 16 songs.
After purchase Balance in gift card = $0
⇒ Cost of 16 songs = $20
⇒ Cost of 1 song = 20/16 = $ 1.25
let x represent number of songs purchased and y represent balance on her gift card.
So, Cost of x songs = 1.25 × x = 1.25x
And Balance = 20 - 1.25 x
Thus, Required equation representing relationship between balance on gift card and number of song purchased.
y = 20 - 1.25x
1.25x + y = 20
If we multiply both sides of equation with 4, we get
5x + 4y = 80
Therefore, 2nd Option is correct.
