Answer:
56
Step-by-step explanation:
The ratio is 5 to 2, and we must keep it this way.
For example, if he had 10 regular sodas then the ratio would be 10:4.
If something happens to one side of this ratio, it needs to happen to the other so it remains balanced.
We need to find out how 5 got to 140. To find out, simply divide 140 by 5.
140 divided by 5 = 28
So, 5 was multiplied by 28 to get to 140.
Now, we need to multiply the 2 by 28 as well so it remains balanced.
2 x 28 = 56.
So, there are 56 diet sodas.
Answer:
6) 5(1/3)
7) 5(1/3)
8) 3(3/5) or 18/5

Answer:
1.4
Step-by-step explanation:
If 1 mile is equal to 1.6 kilometres, then 20 miles will be equal to 20 x 1.6 = 32 kilometres
So it travels 32 kilometres per second
For the second part, if the earth travels 32 kilometres in 1 second, then it will travel 32 x 8 kilometres in 8 seconds, which is equal to 256 km
Answer:
5sqrt2 or -5sqrt2(It might not make sense because I couldn't really do everything on this platform but it is right)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−x2+50=0
For this equation: a=-1, b=0, c=50
−1x2+0x+50=0
Step 2: Use quadratic formula with a=-1, b=0, c=50.
x=
−b±√b2−4ac
2a
x=
−(0)±√(0)2−4(−1)(50)
2(−1)
x=
0±√200
-2
x=−5√2 or x=5√2
