area = lengh x width is that enough of the formula? :D
Step-by-step explanation:
I'll give you the rest, just in case :P My brain got tired at the break before spring, here is the rest
400 = (L+30) X w
400 = 10+30 x 10 ( just b/c I can see 40 x 10 would be 400, calculus could also figure this out for us, but... that would be the minimum fencing he needs to buy and this questions isn't asking that, just make it fit on the back of his house, which we are not given, so just make up something, I used 10 b/c it was convenient )
400 = 40 x 10
2 sides are 40 , and one side is 10
so 90' of fence is needed
Answer:
30 minutes after biker left
Step-by-step explanation:
Given that :
Speed of hiker = 3 mph
Speed of biker = (3 +6) = 9 mph
Present Distance of hiker when the biker set out ;
Present Distance of hiker = speed * time = (3 * 1) = 3 miles
Time taken to catchup equals :
Present distance + (distance when biker set out) = bikers distance
Let time taken = x
(3 + (3 * x)) = (9 *x)
(3 + 3x) = 9x
3 + 3x = 9x
3 = 9x - 3x
3 = 6x
x = 3/6
x = 1/2 hours
x = 30 minutes

Step-by-step explanation:
Answer: just use PEMDAS
[(30+6) -3'2] / 9'2
= (36 -9)/ 9'2
= 27/9'2
= 3'2
= 6
Step-by-step explanation:
252,259,266
let the consecutive multiples be 7(n-1) , 7n and 7(n+1)
so 7(n-1)+7n+7(n+1)=777
or 3n=111,
n=37
