The constant rate of change is 2
(The y intercept is 20 so subtract 20 from the y and divide by 2 to get your x)
Rational is the number that cam be represented by an ordinary fraction, as:
2/5
0.6
1.3333....
Irrational is the number that cannot be represented by an ordinary fraction. It have infinity decimals after decimal point and it is non-periodic, as
0,01001000100001...
Answer:
280 ml as a percentage of 140 l is 0.2%
Step-by-step explanation:
- Note that 1 liter = 1000 milliliters
- To find a percentage of a number divide the number by the total and multiply the quotient by 100%
∵ There is an amount of 280 ml
∵ The total amount is 140 l
→ Change the liter to milliliters using the 1st point above
∴ 140 l = 140 × 1000 = 140000 ml
∴ 140 l = 140,000 ml
→ Now divide the amount by the total, then multiply the quotient by 100%
∵ 280 ÷ 140,000 =
∵ × 100% = 0.2%
∴ 280 ml as a percentage of 140 l is 0.2%
Part A:
Given that <span>Martha can complete 15 activities a day at summer camp and she can choose between crafts or sports.
Let x be the number of crafts activity Martha did and let y be the number of sports activity Martha did.
The equation representing the situation is given by
x + y = 15
Part B:
There are many possible combinations of crafts and sports that Martha can do.
3 possible combinations of crafts and sports that Martha can do are
7 crafts and 8 sports
4 crafts and 11 sports
8 crafts and 7 sports

You work it out like this
13+5 = 18
31-5= 26
18+3 =21
26-3 = 23
so middle = 22
ANSWER: 22
