He now has 44 so subtract 17 from that and you get 27 (1/2 of the number of his original stamp collection). Then add 27 +27 and you get 54. I believe 54 is the answer. Hope that helps!
Answer:
6
Step-by-step explanation:
x/8 = 9/12
We can use cross products to solve
x*12 = 8*9
12x = 72
Divide each side by 12
12x/12 = 72/12
x=6
Answer:
5.2%
Step-by-step explanation:
Volume of cylinder= πr²h
In Container A,
D= 18ft, r=18/2=9ft, h=15ft
volume= 22/7 × 9² × 15
= 26730/7 cubic ft.
In Container B,
D=16ft, r= 16/2=8ft, h=18ft
volume= 22/7 × 8² × 18
= 25344/7 cubic ft.
percent of amount of water left in Container A= percent of container A that is full after pumping
Amount of water left in Container A,
26730/7 - 25344/7 = 1386/7
Therefore, % of container A that is full= 1386/7 ÷ 26730/7 × 100
(1386×7×100)/(7×26730)= 5.185
To the nearest tenth= 5.2%
Prove that sin 2x cos 2x=sin 3xx sin of the equation
Lets smaller number is x
<span>The greater number is 8 more than the smaller number : x + 8
</span><span>The sum of two numbers is 72: x +( x + 8)= 72
answer
</span><span>x + (x + 8) = 72</span>
