We simplify 5:20 and 9:36 as 1:4
Since they are both equal to 1:4, the total ball ratio should also be equal to 1:4
x:56 = 1:4
(x:14) : (56:14) = 1:4
(x:14) : 4 = 1:4
So, x : 14 = 1
x = 1.14 = 14.
I am certain the answer is A and D. Plze mark me brainiest:)
The total of the internal angles in a tetradecagon is 2160.
2160 - 2012 = 148
The remaining angle must be 148 degrees.
1) The larger number is 33.
2) Joan weighs 47.5 kg, and Annie weighs 44.5 kg.
3) Ronnie walks at a rate of 4 km/h, while Margie walks at a rate of 2 km/h.
4) It takes 3 hours for Lea to do the same task working alone.
5) Katie is 5 years old and Rico is 1 year old.
To solve each problem, the following calculations must be done:
1)
(54 - 12) / 2 = X
42 / 2 = X
21 = X
21 + 12 = 33
33 + 21 = 54
2)
(92 - 3) / 2 = X
89 / 2 = X
44.5 = X
44.5 + 3 = 47.5
44.5 + 47.5 = 92
3)
1000 / 3 x 2 = 666.666
0.666 x 6 = 3.999
0.333 x 6 = 1.999
4)
1/5 + 1/X = 1/2
10/5 + 10/X = 10/2
2 + X = 5
X = 5 - 2
X = 3
5)
5 /// 1
8 /// 4
