Well first of you need to know that on a straight line there should be 180 degrees. Also a triangle has 180 degrees in total. Now if this is to scale then you can always measure the angle BCA and explain how you took that away from 180 to get whatever. Assuming otherwise i don't know how one can actually complete this question without any measurements, at least one and it would be something anyone can complete. Even if you didn't have anything it should be a equilateral triangle or isosceles. That way you can work out the inside sides than the exterior. But since it's not, I'm not to sure.

An office equipment store buys highlighter pens boxes at a wholesale price of $15 each. It then marks up the price by 94%, and s

Stells [14]

Answer:

Option (d) is correct.

Step-by-step explanation:

Given that,

The wholesale price of a pen is $15.

It then marks up the price by 94%.

Its marked price is equal to 94% of $15. So,

$\text{MP}=\dfrac{94}{100}\times \$15\\\\\text{MP}=\$14.1$

Selling price of the highlighter pen is equal to the sum of marked price and the wholesale price.

SP = $14.1+$15

SP = $29.1

Hence, the marked price is $14.1 and the selling price is $29.1

The expressions a(8x+7) and 4x+3.5 are equivalent. What is the value of a?

valentina_108 [34]

Answer:

a=1/2

Step-by-step explanation:

From the question, the expression a(8x+7) is equivalent to 4x+3.5

Which means that multiplying 8x by a gives 4x and multiplying 7 by a gives 3.5

So, we can write the following to find the value of a

$a(8x+7)\equiv 4x+3.5$

we can write the following

8ax=4x

$\implies a=\frac{4x}{8x}= \frac{1}{2}$

Hence the value of a is 1/2
