Percentage of tress under 30 = 6/75 x 100 = 8%
Answer: 8%
Answer:
<u>The sum of their ages now is 13</u>
Step-by-step explanation:
Dally's age = x
Dilly's age = x - 7
In 4 years time Dilly will be half Dally’s age, therefore:
Dilly's age plus four equals to half of Dally’s age plus four,
replacing with the values and variables we know:
x - 7 + 4 = (x + 4) /2
x - 3 = (x + 4) /2
2x - 6 = x + 4 (Multiplying by 2 at both sides)
2x - x = 4 + 6 (Like terms)
x = 10 ⇒ x - 7 = 3
<u>The sum of their ages now is 13 (10 + 3)</u>
Can you please add a link to the question so I can see the image?
Answer:
a) Total cost = 49 + 38.75m
b) Total cost = 149 + 38.75m
c) The graphs of the lines are parallel and both has slope of - 2.5
d)Difference in total cost = $132.5
Step-by-step explanation:
Total cost , TC = Initial membership fee + monthly charges
a) TC = 49 + 38.75m
b)TC = 149 + 38.75m
d) 149 + 38.75(6months) = 381.5
49 + 38.75(12months) = 514
Difference in total cost = 514 -381.5 = $132.5
First, you want to put all the numbers in order from least to greatest.
21, 33, 33, 42, 67, 79, 89
Now, you can use this song to help remember how to do these problems.
Cross off the sides till you get to the center. 1 is good, 2 is bad. (If you get two numbers in the middle) add then divide by two.
Cross off 21, then 89, then 33, then 79, then 33, then 67. Now, you're left with 42 in the middle. That is your median. Hope this helps! :)
