Answer:
1/6
Step-by-step explanation:
Answer: 1:3
Step-by-step explanation: for 4 toads you have 12 frogs so the ratio is 4 to 12. But you can simplif, divide each side by 4 so it’s 1 to 3
Answer:
<h2>
100, -50, 25, -12.5, 6.25, -3.125, 1.5625, -0.78125</h2>
Step-by-step explanation:
Each term is being multiplied by <u>-0.5</u>
How did I know?
Divide the second term by the first.
-50 divided by 100 = -1/2
Find the last four terms.
-12.5 x -1/2 =<em> </em><u><em>6.25</em></u>
6.25 x -1/2 = <u><em>-3.125</em></u>
-3.125 x -1/2 = <u>1.5625</u>
1.5625 x -1/2 =<em><u> -0.78125</u></em>
Step-by-step explanation:
the distributing ratio is 2:5.
that means for every 2 white marbles there must be 5 blue marbles.
so, we are taking about "groups" or multiples of 7 (2+5 = 7).
now, even 7×7 = 49 is too small.
but the next multiple of 7 (7×8 = 56) is now big enough to include at least 50 marbles.
so, in order to keep the 2:5 ratio strictly in place, the minimum number of marbles in the bag is 56.
Let w be the width of the barn; and 2w+10 be its' length. Then:
w(2w+10)=208
2w²+10w-208=0
w²+5w-104=0
(w+13)(w-8)=0
w=8
2w+10=26
