Answer:
or one seven eighteenths
Step-by-step explanation:
we know that
12 one half times one nine is the same that multiply 12 one half by one nine
so

Convert mixed number to an improper fraction

substitute

Convert to mixed number

therefore
12 one half times one nine is one seven eighteenths
Answer:
Step-by-step explanation:
Part A
xf = xo + vo* t + 1/2 a*t^2 Subtract xo
xf - xo = 0*t + 1/2 a*t^2 multiply by 2
2(xf - xo) = at^2 divide by t^2
2(xf - xo ) / t^2 = a
Part B
Givens
xo =0
vo = 0
a = 10 m/s^2
xf = 120 m
Solution
xf = xo + vo* t + 1/2 a*t^2 Substitute the givens
120 = 0 + 0 + 1/2 * 10 * t^2 Multiply by 2
120*2 = 10* t^2
240 = 10*t^2 Divide by 10
240/10 = t^2
24 = t^2 take the square root of both sides.
√24 = √t^2
t = √24
t = √(2 * 2 * 2 * 3)
t = 2√6
Answer:
$7.00
Step-by-step explanation:

4a) 1 oz of coffee is equal to 0.35c, which is consistent with everything in the table.
4b)Knowing this, if we have 20 oz of coffee, and we multiply it by 0.35, we will get how much it costs for this cup.
20*0.35 = 7.00
Hope this makes sense and feel free to ask questions!

First we'll multiply the second equation by -2

Now let's add the new equation and the first one.

We found y's value. We'll plug it in one of the equations to find x's value.
