Just find the slope between the points
basically find (f(10)-f(7))/(10-7)
f(7)=7^2-3(7)-4=49-21-4=24
f(10)=10^2-3(10)-4=100-30-4=66
slope=(66-24)/(10-7)=42/3=14
average rate of change is 14
Answer:
The constant value (often written k) relating amounts that rise or fall uniformly together. It is the ratio of the amounts y and x: k = y/x. Put another way: y = kx.
Answer:
5 friends
Step-by-step explanation:
Candy pieces = 60
Chocolate = 45
What should be the smallest number of her sister's friends for the distribution of candy and chocolate so each friend gets an equal number of candy pieces and chocolates in a way that there should not be left any chocolate or candy pieces left over?
To calculate this, find the lowest factor of 60 and 45
60:
Factors = 2, 4, 5, 6,
45:
Factors= 3, 5, 9
The lowest common factor of 60 and 45 is 5
The smallest number of her sister's friend so each person get an equal number of candy pieces and chocolate so there won't be any leftover is 5
That is
If there are 5 friends at the birthday party
60 candy pieces among 5 friends
= 60/5
= 12 pieces each
45 chocolate among 5 friends
= 45/5
= 9 each
To solve, you need to find the least common multiple of the denominator.
In this case, its 30.
3*9= 27/30
1*10 = 10/30
She walked 37/30 miles or 1 mile and 7/30th of a mile
Step-by-step explanation:
1)
2 1/10 + 3/100 = 200/100 + 10/100 + 3/100 = 213/100 =
= 2 13/100
2)
2 1/10 + 5 3/100 = 200/100 + 10/100 + 500/100 + 3/100 =
= 713/100 = 7 13/100
3)
2.1 + 00.3 = 2.4
or did you mean + 100.3 ? then is is 102.4
4)
24/100 + 7/10 = 24/100 + 70/100 = 94/100 = 47/50
5)
3 24/100 + 8 7/10 =
= 300/100 + 24/100 + 800/100 + 70/100 =
= 1194/100 = 11 94/100 = 11 47/50
