2/3 is equal to 4/6.
So, Beth ran further by 1/6 of the marathon
Answer:
3. 3:5
4. 4:1
Step-by-step explanation:
Just ratios I believe, myb if it's wrong but that should be it.
Since 3 & 5 aren't divisible by anything the scale factor is just 3:5.
Since 24 & 6 are divisible by a common number, being 6, you'd divide 24:6 & get a scale factor of 4:1.
Eliminating any brackets that there are.
Hope this helps :)
THE ANSWER IS 18.84144 BUT IT FALLS BETWEEN 17 AND 19
The answer to problem one is the value 96
=============================================
Explanation:
(g o h)(-7) is the same as g(h(-7))
We need to find the value of h(-7)
h(t) = t^2+1
h(-7) = (-7)^2+1 ... replace t with -7
h(-7) = 50
g(h(-7)) turns into g(50) after we replace "h(-7)" with "50"
Now compute g(50)
g(t) = 2t-4
g(50) = 2*50-4
g(50) = 96
So because g(50) is the same as g(h(-7)), this means g(h(-7)) = 96
Since (g o h)(-7) is the same as g(h(-7)), this means (g o h)(-7) = 96
