15 cm 16.6 cm area cm2

Ymorist [56]

Answer:

357.1573 (If you don't round)

Step-by-step explanation:

To find area of a rectangle is to multiply length by width, which in this situation would be 15 by 16.6, which is equal to 249. Next, we need to add this to the area of the semicircle. The area of a semicircle is equal to 1/2 * pi * radius^2 (Because a semicircle is half a circle and a circle's area is pi * radius^2). The radius is equal to half the diameter, which in this case is 16.6. 16.6/2 = 8.3, so the radius is 8.3. If we plug this into the equation, we get that 108.1573 is the area of the circle (If you use 3.14 as pi). 108.1573 + 249 is equal to 357.1573.

Here are the first five terms of an arithmetic sequence.

Assoli18 [71]

Answer:

The nth term of an AP will be 27 -7n.

Step-by-step explanation:

First five terms of the Arthemetic Sequence is given to us , which is 26 , 19 , 12 , 5

Hence here Common Difference can be found by subtracting two consecutive terms . Here which is 19 - 26 = (-7) .

Here first term is 26 .

And the nth term of an AP is given by ,

★ T_n = a + ( n - 1) d

Substituting respective values ,

⇒ T_n = a + ( n - 1 )d

⇒ T_n = 26 + (n - 1)(-7)

⇒ T_n = 26 -7n+1

⇒ T_n = 27 - 7n

<h3>Hence the nth term of an AP can be found using T_n = 27 - 7n. </h3>

Are these two claims equivalent, in conflict, or not comparable because they're talking about different things?

These two claims about markup and margin are equivalent because they discuss differently the same issue.

<h3>What are markup and margin?</h3>

A markup is a profit percent added to the cost price to determine the selling price. Thus, markup relates the percentage of profit to the cost price.

The profit margin relates the percentage of profit to the selling price.

<h3>Data and Calculations:</h3>

Selling price = 100%

Profit margin = 25%

Cost price = 75% (100% - 25%)

Markup = 33% (25%/75% x 100)

Thus, these two claims about markup and margin are equivalent.
