7h+3s=27.95 subtract 7h from both sides
3s=27.95-7h divide both sides by 3
s=(27.95-7h)/3
Then we are told:
5h+4s=23.4, using s found above makes this equation become:
5h+4(27.95-7h)/3=23.4 multiply both sides by 3
15h+4(27.95-7h=70.2 perform indicated multiplication on left side
15h+111.8-28h=70.2 combine like terms on left side
-13h+111.8=70.2 subtract 111.8 from both sides
-13h=-41.6 divide both sides by -13
h=$3.20
Answer:
33/100
Step-by-step explanation:
I am not so sure, I calculated the percentage and tried converting it to a fraction this is what I got, :)
It is 0.35 That is the answer.
Given:
Two chords intersect each other inside the circle.
To find:
The value of x.
Solution:
According to intersecting chords theorem, if two chords intersect each other inside the circle, then the product of two segments of one chord is equal to the product of two segments of second chord.
In the given circle,
Divide both sides by 2.
Splitting the middle term, we get
Using zero product property, we get
or 
or 
For , the side AE is negative. So, is not possible.
Therefore, the required solution is .
Answer:
$0.03
Step-by-step explanation:
The 1.4% interest rate given is an annual rate. So, the daily interest rate is 1/365 of that value. The first day's interest is 1/365 of 1.4% of $720:
1/365 × 0.014 × $720 ≈ $0.0276 ≈ $0.03 . . . . first day's interest
