Answer:
21+/-sqrt(253)=x
So one value for x is 21+sqrt(253)
and another is 21-sqrt(253)
Problem:
Given (21,7) and (x,1), find all x such that the distance between these two points is 17.
Step-by-step explanation:
Change in x is x-21
Change in y is 7-1=6
distance^2=(change in x)^2+(change in y)^2
17^2=(x-21)^2+(6)^2
289=(x-21)^2+36
Subtract 36 on both sides:
289-36=(x-21)^2
253=(x-21)^2
Take square root of both sides:
+/-sqrt(253)=x-21
Add 21 on both sides:
21+/-sqrt(253)=x
I think you would need 48 quarts of red. The way I see it, it is a ratio of 5:8 and the current ratio is 30:x. Divide 30 by 5 to get 6, and the multiple 8 by 6 to get the new part of the ratio
Answer: jet b
Step-by-step explanation: jet a: 510 divided by 5= 102
jet b: 460 divided by 4= 115
jet a will fly 102 miles in one hour
jet b will fly 115 miles in one hour
this means that jet b has the better rate because it flies more in one hour compared to jet a
:)
It will take you 2 hours since ur going 70 mph divide the 140 mph by 70mph . Hope this helps :)
