Step-by-step explanation:

<em>The</em><em> </em><em>given</em><em> </em><em>sequences</em><em> </em><em>are</em><em>;</em>

<em>2</em><em>,</em><em>7</em><em>,</em><em>1</em><em>2</em><em>,</em><em>1</em><em>7</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em>

<em>difference</em><em> </em><em>=</em><em>5</em>

<em>by</em><em> </em><em>using</em><em> </em><em>formula</em><em>,</em>

<em>we</em><em> </em><em>get</em><em>,</em>

<em>tn</em><em>=</em><em>a</em><em>+</em><em>(</em><em>n-1</em><em>)</em><em>d</em>

<em>tn</em><em>=</em><em> </em><em>2</em><em>+</em><em>(</em><em>n-1</em><em>)</em><em>5</em>

<em>Therefore</em><em>,</em><em> </em><em>tn</em><em> </em><em>is</em><em> </em><em>5</em><em>n-3</em><em> </em><em>is</em><em> </em><em>required</em><em> </em><em>formula</em><em> </em><em>for</em><em> </em><em>this</em><em> </em><em>arithmetic</em><em> </em><em>sequences</em><em>.</em>

One kilogram is 2.2 pounds. If i had 1 pound would that be 0.45 kilograms why or why not?
prisoha [69]

Step-by-step explanation:

1 kg = 2.2 pounds

0.45 kg = 1 pounds to see whether it's correct or not we can cross multiply the given equations

multiply 1 kg with 1 pounds and 0.45 kg with 2.2 pounds then check if they are equal

1 × 1 = 2.2 × 0.45

1 = 0.99 as you can see this is not an equality therefore the statement is wrong.

Which statements can be used to prove that ABC and A’B’C are congruent?
Nadusha1986 [10]

Answer:

O A.

Step-by-step explanation:

<u>Option A</u> identifies two angles (sufficient for similarity) and one side, sufficient (with similarity) for congruence. The applicable congruence theorem is AAS.

<u>Option B</u> identifies two sides and the angle not between them. The two triangles will be congruent in that case only if the angle is opposite the longest side, which is <u>not true</u> in general.

<u>Option C</u> same deal as Option A.

<u>Option D</u> identifies three congruent angles, which will prove the triangles similar, but not necessarily congruent.
