If the total value of the coins is $15. The number of each type of coin is: 31 quarters, 72 dimes.
<h3>Number of each type of coin</h3>
Let D = number of dimes
Let Q = the number of quarters
Equations
d + q = 103
0.10d + 0.25q = 15
d = 103 -q
0.10(103 -q) + 0.25q = 15
10.3 - 0.10q + 0.25q = 15
0.15q = 4.7
q=4.7/0.15
q=31 quarters
Substitute q into second equation
D+31=103
D=72 dimes
Therefore the number of each type of coin is: 31 quarters, 72 dimes.

Answer:
Option A. a loss of 93.98 points
Step-by-step explanation:
To solve this question we will calculate the difference (change)in closing amount of Dow Jones on stock market that took place on day to day basis.
From 01/27 to 01/28
Change = 13881.93 - 13895.98 = (-14.05)
From 01/28 to 01/29
Change = 13954.40 - 13881.93 = (+72.42)
From 01/29 to 01/30
Change = 13860.42 - 13954.40 = (-93.98)
Here we can see that change from 01/29 to 01/30 is maximum and it is (-93.98).
Therefore answer will be Option A. a loss of 93.98 points.
Answer:
Its a set that has a finite number of elements.
Step-by-step explanation:
D=rt and we are told d=546 and r=1.3m/s so
1.3t=546 divide both sides by 1.3
t=420 seconds so
420s(min/60s)=7 min
So it takes him 7 minutes to walk to Sara's house.
