Let’s make x = # of nickels. Then 3x = # of dimes and 3x+6 = # of pennies. A nickel is 5 cents, a dime is 10 cents and a penny is 1 cent.
The money she has should be .05(x) + .10(3x) + .01(3x+6) = 4.62 or to make it simpler: 5(x) + 10(3x) + 1(3x+6) = 462.
5x + 30x + 3x + 6 = 462
38x + 6 = 462
38x = 456
x = 12.
So she has 12 nickels (12 * $0.05 = $0.60), 36 dimes (36 * $0.10 = $3.60) and 42 pennies (42 * $0.01 = $0.42). $3.60 + $0.60 + $0.42 = $4.62.
He has 9 bowls...and each bowl holds ,at most, 12 fish...so he can house (12 * 9) = 108 fish at most.
so... no, he does not have enough bowls ....he only needs one more bowl
Answer: Irrational
Step-by-step explanation:
Answer:
a) 0
b) scalene and obtuse
Step-by-step explanation:
∠A = 20
∠B = 60
∠C = 180 - 20 - 60 = 100 (obtuse)
Since none of the angles are equal, no sides are equal either
So, it's a scalene triangle
Since one angle is obtuse, it's an obtuse triangle
