Answer:
r = - 
Step-by-step explanation:
Given that r varies inversely as t , then the equation relating them is
r = 
← k is the constant of variation
To find k use the condition t = - 6 when r = - 2, then
- 2 = 
( multiply both sides by - 6 )
12 = k, thus
r = 
← equation of variation
when t = - 7, then
r = 
= -
Domain is the x intercepts and range is the y intercepts.
So for this one, all of the ones in the x column would be the domain values.
C. (1,2,3,4) would be your answer.
good luck on the rest of your test!
Answer: 12
40% = 40/100 = 0.40
"of" means "multiply" in percent word problems like this. Multiply 0.40 with 30 to get 0.40*30 = 12
Optionally, you can solve the equation below for x
part/whole = percent/100
x/30 = 40/100
x/30 = 0.40
x = 0.40*30
x = 12
much of those steps follow a similar pattern to what was mentioned earlier.
The answer in 25.50 Please Give me brainest. what is 35% of $85. divide 30 into 100 30/100. 0.3. then you multiply the decimal by 85.00 dollars. 0.3 × 85 = 25.5 so 25.50
