Answer:
Not proportional.
Step-by-step explanation:
Given ratios:
To tell whether the ratios are proportional or not.
Solution:
In order to tell whether the given ratios are proportional or not, we will reduce the fractions to the simplest numbers by dividing the numerator and denominator by their greatest common factor and then comparing them. If they are equal then the ratios are proportional else not proportional.
So, the simplest form of 4/2 can be calculated by dividing both by 2 as it is the G.C.F.
the simplest form of 8/6 can be calculated by dividing both by 2 as it is the G.C.F.
Now, since 2/1 does not equal 4/3, hence the ratios are not proportional.
Answer:
Step-by-step explanation:
slope=(vertical distance)/(horizontal distance)=(6.25)/25=0.25
Answer:
cos (a+b)= cos a cos b - sin a sin b
Step-by-step explanation:
I had to answer this question too, but I don't know the explanation. I just saw it in this Khan Academy video. https://www.khanacademy.org/math/precalculus/x9e81a4f98389efdf:trig/x9e81a4f98389efdf:angle-addition/v/cosine-addition-identity-example

Step-by-step explanation:
Answer:
8 times larger
Explanation:
Since your doubling the dimensions of the rectangular prism and to the regular formula is a*b*c
The equation to find how many times larger it is would be
2^3
2^3 = 8
Hope this helps you and others!!
