Which of the following is an arithmetic sequence?
masha68 [24]

Answer:

B

Step-by-step explanation:

And arithmetic sequence is a sequence in which the difference between each of the numbers are constant.

It is not A, because the difference between 3 and 9 is positive 6, and the difference between 9 and 81 is positive 72.

It is not C, because the difference between 4 and 1 is -3, and the difference between 1 and 4 is positive 3.

It is not D, because the difference between 2 and -2 is -4, and the difference between -2 and 2 is positive 4.

And it is B because the numbers maintain a constant difference between each other, which is -3.

Please help me with the question please ASAP ASAP please please ASAP please please help please please ASAP please please IM BEGG
Oksi-84 [34.3K]

Answer:

Ok if you look at the figure, it is a vertical angle. This means that the angle opposite to each other is congruent.

m<1 is congruent to m<3

m<2 is congruent to m<4

m<3 is 60⁰ and is congruent to m<1. This means that m<1 is 60⁰. m<4 is 30⁰ and is congruent to m<2. This means that m<2 is 30⁰.

m<1 = 60⁰

m<2 = 30⁰

m<3 = 60⁰

m<4 = 30⁰

Hope this helps, thank you :) !!

HELP!!!

We can define variable as<span> any factor, trait, or condition that can exist to vary or change.
</span>
Perimeter of rectangle = 2(l+w)
let l is the length of the garden
and w is the width of the garden =<span> 6 less than the length = l - 6
perimeter = 188 feet
p = 2(l+w)
188 = 2 (l + (l-6))
188 = 2(l + l - 6)
188 = 2(2l-6)
188 = 4l - 12
4l = 188+12
4l = 200
l=50 
w = l - 6 = 50 - 6 = 44
Thus, the dimensions, length is 50 feet and width is 44 feet.</span>
