4. proportional
5. proportional
6. I don't know what functions are
7. It has a straight line and distance is proportional to time.
Answer:
A:1
Step by step explanations:
C(n,r)=C(5,5)
n=5
r=5
=n! / (r!(n-r)!)
=5! / (5!(5-5)!)
=1
The base value is the current value
Good luck! I hope this helps!
Subtract the number she completed from what she had left to paint originally.
The fractions have different denominators so first step is to rewrite the fractions with a common denominator.
23/25 can be rewritten as 92/100
Now you have 78 21/100 - 34 92/100
Because 21/100 is smaller than 92/100 subtract 1 whole number from 78 and rewrite 1 as 100/100 and add that to the fraction.
78 21/100 becomes 77 121/100
Now subtract :
77 121/100 - 34 92/100
77-34 = 43
And 121/100 - 92/100 = 29/100
Combine to get 43 and 29/100
