2 7/10 + 5/8 what is the answer

2 answers:

Well you first must get the fractions to have the same denominator. So you multiply 5/8 by 10 ( both top and bottom ) to get 50/80, and you multiply 7/10 by 8 to get 56/80. You ignore the whole 2 for now for it is not a fraction, and you add 56 plus 50 to get 106 and put it back over 80. 106/80, now since 106/80 is over 1 you can take 106 - 80 and get 26. 1 and 26/80 is what the two fractions add up to. Add the whole two to 1 and get 3 and 26/80 which can be simplified to 3 and 13/40.

Step-by-step explanation:

42/n³∑k²+12/n²∑k+30/n∑1

=42/n³[n(n+1)(2n+1)/6]+12/n²[n(n+1)/2]+30/n [n]

=7n(n+1)(2n+1)/n³+6n(n+1)/n²+30

=7(n+1)(2n+1)/n²+6(n+1)/n+30

=[7(2n²+3n+1)+6(n²+n)+30n²]/n²

=[14n²+21n+7+6n²+6n+30n²]/n²

=[50n²+27n+7]/n²

=[50+27/n+7/n²]

→50 as n→∞

because 1/n,1/n²→0 as n→∞

Answer:

Step-by-step explanation:

It must be the same as the angle opposite of it.

You can see that 134 and 134 are the same, so the other two corners need to be the same and be 46 and 46.

What is the answer, she explanation pls

Bingel [31]

Answer: OPTION D.

Step-by-step explanation:

First, it is important to know the definition of "Chord" and "Arcs" in circles.

A Chord is defined as a segment that joins any two points of a circle.

An Arc is defined as portion of the circumference of a circle.

By definition:

1) If two chords of a circle are congruent (which means that they have equal measure), then their intercepted Arcs are also congruent.

2) If the Arcs are congruent, then they have congruent chords.

In this case, you know that the Arc GH and the Arc JK are congruent. Therefore, you can conclude that the Chord GH and the Chord JK are also congruent.

Then, knowing that:

$GH=9\ units$

You can determine that:

$JK=9\ units$

Answer:

Step-by-step explanation:

10x40 = 400

2(39+42)+ 40 x 4 + 41 + X = 400

162 + 160 + 41 = 400 - X

400 - 363 = X

X= 37
