Answer:
25 = base
Step-by-step explanation:
I searched all of this on YT to try and help
so first we need to know the area of a Trapezoid
A = 1/2h(b + b)
86 = 1/2(18 + b)4
we dont know the base where going to put b
we also dont like fractions so where going to get rid of 2 by multiplying 2 by 2. And we do it in both ends, so where doing the same with our Area.
172 = (18 + b)4
the 4 is multipling so divide it on both ends.
43 = (18 + b)
then do the opposite operation on the 18, by subtracting 18 on both sides.
25 = b
is the base
check the work by plugging it back in
A = 1/2h(b + b)
A = 1/2 4(18+25)
A = 1/2 4(43)
A = 1/2(172)
A = 86in
Answer:
i got 21.146
Step-by-step explanation:
multiply 5.45 x 3.88 and thats the answer. it may need to be rounded.
21.10?
By definition the rate of change of a function is given by:
Or equivalently:
Substituting the values given in the problem we have:
Rewriting we have:
Answer:
the rate of change of the ramp is:
Answer:
2n - 3
Step-by-step explanation:
twice means multiply by 2
decreased by 3 means subtract 3
"a number" n
"twice a number" 2n
"twice a number decreased by 3" 2n - 3
