The triangles given below in the diagram are similar by; D: The SSS Similarity theorem.

<h3>How to interpret similar triangles?</h3>

From triangle similarity theorems, we know that;

If a segment is parallel to one side of a triangle and intersects the other two sides, then the triangle formed is similar to the original and the segment that divides the two sides it intersects is proportional.

Now, from the given diagram, we see the ratio of corresponding sides are congruent as;

45/30 = 54/36 = 36/24 = 1.5

Thus, the triangles are similar by SSS similarity theorem

You want to buy three books that are on sale at 20% off. The original prices of the books are $2.50, $4.95, and $6.00. How much

Veseljchak [2.6K]

Answer:

$2.69

Step-by-step explanation:

The original prices of the books are $2.50, $4.95, and $6.00.

You want to buy three books that are on sale at 20% off (or 0.2 as decimal).

In total, you'll save:

$0.2\cdot \$2.50+0.2\cdot \$4.95+0.2\cdot \$6$

Uce distributive property:

$0.2\cdot \$2.50+0.2\cdot \$4.95+0.2\cdot \$6\\ \\=0.2\cdot (\$2.50+\$4.95+\$6.00)\\ \\=0.2\cdot \$13.45\\ \\=\$2.69$

87th term of 12,0,-12

Elan Coil [88]

Answer:

$a_{87} = -1020$

Step-by-step explanation:

Given:

The given AP is.

12,0,-12,......

$n=87$

The first term of an AP $a=12$

Common difference $d=0-12=-12$

We use the the formula for nth term of an AP.

$a_{n} = a+(n-1)d$

for 87th term

$a_{87} = 12+(87-1)(-12)$

$a_{87} = 12+(86)(-12)$

$a_{87} = 12+(-1032)$

$a_{87} = 12-1032$

$a_{87} = -1020$

Therefore, The 87th term of given series is -1020.

A politician's support grew from 42% by 3 percentage points to 45%. What percent (relative) change is this? Round your answer to

gregori [183]

Answer:

7.1%

Step-by-step explanation:

The formula for percentage relative change =

[Final value - Initial value/Initial value] × 100

From the above question

Initial value = 42 %

Final value = 45%

= 45 - 42/ 42 × 100

= 3/42 × 100

= 7.1428571429 %

Therefore, approximately to the nearest tenth, the percentage relative change = 7.1%
