Answer:
∠ B ≈ 62.73°
Step-by-step explanation:
Using the sine ratio in the right triangle.
sinB =
=
=
, thus
∠ B =
(
) ≈ 62.73° ( to the nearest hundredth )
Answer:
$22.75
Step-by-step explanation:
C = $30.25 - ($0.25/min)x, where x is the number of minutes spent on calls
Here, 30 minutes of calls result in this amount of $ left on the card:
C(30) = $30.25 - ($0.25/min)(30 min) = $22.75
Fist lets find the % of people using boats
100%- (36+53+2)= 9%
then find the number of people of 9%
200= 100%
B=9%
100B=200x9
B= 18
Number of pennies:P
Number of nickels:N
Number of dollar bills:D
P=N+12
N=D+5
1P+5N+100D=996
^given
Therefore
P=(D+5)+12
P=D+17
Plug back into main equation
(D+17)+5(D+5)+100D=996
Combine like terms
106D+42=996
106D=954
D=954/106=9
9 Dollar bills
N=D+5
N=(9)+5=14
14 Nickels
P=N+12
P=(14)+12=26
26 Pennies
26*1+14*5+9*100=996
Final answer:
9 Dollars
14 Nickels
26 Pennies
5 letters 2 tiles each = 10 total tiles
2 are A and 2 are E so 4 possible tiles
