The probability of picking a dime first would be: 6/10
Answer:
$25
Step-by-step explanation:
We know that in 3 weeks you get $15 now you can divide 3 by 15 to get $5 per week so since we know how much you earn per week you multiply $5 by 5 weeks to get $25
Answer:
larger number = 35
smaller number = 26
Step-by-step explanation:
let larger number be x
and another ( x-9 )
so, x+x-9=61
2x = 70
x = 35
smaller number = 35 - 9
= 26
Answer:
N0 solution.
Step-by-step explanation:
x=-2y+1....(1)
x+2y=9....(2)
put equation (2) to equation (1)
-2y+1 + 2y=9
combine
-2y + 2y=9-1
0=8
No solution.
Answer:
1232 m^3 to nearest whole number.
Step-by-step explanation:
The volume of a cone = 1/3 π r^2 h where r = radius of base and h = height.
The radius of the base = 1/2 * 14 = 7m.
The height can be found by using the Pythagoras theorem:
25^2 = h^2 + 7^2
h^2 = 625 - 49 = 576
h = √576 = 24m
So the volume = 1/3 π * 7^2 * 24
= 1231.504 m^3.
