So if you have 9 cats and they each have 9 kittens, then a reasonaable estimate is 10 times 9 since 10 is close to 9 so that is 90 and the answer is 81
you would knwo if you got 988387479 kittens if you got a problem because that is nowhere close to 90
and who do you call? ghostbusters!
Answer:
BE=7 un., EC=5 un.
Step-by-step explanation:
Triangles ABC and ADE are similar, then
Thus,
Therefore,
So
Answer:
7
Step-by-step explanation:
difference between two number let say x&y is x-y
so, difference between their score is (-17)-(-24)
=(-17)+24 {minus of minus is plus}
=24-17
=7
Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2
r=x
r=
Area=
r^2
so..
A=
(
)^2
=
(
)
=
(38-x) is perimeter
then
(
)^2
+ (
)^2
then you graph it and it equals
16.716 cm the circumference of the circle
Answer:
a(n)= a(n+1)+4
Step-by-step explanation:
The first terms of this sequence are: 4,0, -4, -8, -12
Let 4 be a0 and 0 a1.
● a1-a0 = 0-4
●a1-a0 = -4
●a1 = -4+a0
So this relation links the first term with the second one.
replace 1 in a1 with n.
0 in a0 will be n-1
● an = -4+a(n-1)
Add one in n
● a(n+1) = a(n)-4
● a(n) = a(n+1)+4
