<em>Question:</em>
<em>Abraham has visited at least 50 countries; he plans to visit five new countries per year (Y) for the next several years. Which inequality and solution shows the amount of years they will take for Abraham to meet his goal.</em>
Answer:
Step-by-step explanation:
Given
------ at least
Required
Represent as an inequality
"at least" means 
So the countries he has visited can be represented as thus;
If
1 year = 5 countries
y years would be 5y countries
So, in y years; he'd have visited
To determine the value of y.
We have that
<em>in the world</em>
<em>Substitute 195 for Countries</em>
<em>Collect Like Terms</em>
<em>Divide through by 5</em>
<em>Reorder</em>
This means that; he'll visit all countries in at most 29 years' time
Answer:
0 - 20
1 -22
5 - 30
10 - 40
15 - 50
20 - 60
Step-by-step explanation:
The initial amount this equation is 20 so that is why at 0 shirts its still 20 dollars for the set up fee and 2 dollars per shirt. Now that we have this information we can actually make a linear equation
y = 2x + 20
y = the total cost
x = the number of shirts
All you have to do next is plug in the number of shirts to get the total cost
Example: 2(1) + 20 = y
2 + 20 = y
22 = y
Meaning for 1 shirt it would be 22 dollars in total
The population standard deviation, σ = 1.68, the sample standard deviation, s = 1.95, the sample mean =7.23, and the sample size, n = 39.The test statistics is given by
T=(n - 1) (s / σ)²
= (39 - 1) (1.95 / 1.68)²
= 38 (1.35)= 51.196
Answer:
it should be d. 315
Step-by-step explanation:
to find the volume, we need to multiply length x width x height. the base is both width and height together, so if we just multiply the base and the height we should get the volume which would be 315 cubic centimeters.
i have not done the test, so please tell me if im incorrect.
Answer:
supplement: 137
complement: 47
Step-by-step explanation:
Supplement is two angles that equal 180, so just subtract 43 from 180.
complement is two angles that equal 90, so 90-43=47
