c. 30
d. 42

PLEASE HELP!! REALLY STUCK!

Answers

An easy way to do this specific problem is to divide 200 by 2, since it's just two 100s. Now that you have two 100s, it's easy to see that 15% of 100 is 15. Since you have two 100s, multiply 15 by two. In the future, to calculate percentages, use this formula:

is/of = percent/100

is/200 = 15/100
200 * 15 = 3,000
3,000 / 100 = 30

Just add the commission to the amount she earns each week to her total income for this week.

30 + 80 = 110

Renee earned a total of $110 (B) and earned $30 (C) from commission.

200x15%=30$ of commission
80+30=110$ in total for the week

Elone year, Sales increased by 15%.the following year Sales increased by 1.8% to.
calculate the overall percentage increase in sales

Answers

Answer:

increase 15% = 1+(15/100)=1.15

increase 1.8% =1+(1.8/100)=1.018

evolution coefficient: 1.15*1.018=1.1707

overall percentage increase

(1.1707-1)*100=17.07%

How do I have to interpret the 2 in the next log?Is it the same as saying (logx)^2?

I need to calculate the derivative of this function but it will be difficult without even knowing what the 2 means lol.

Thnx in advance
$log^2 x$

Answers

It means you have to multiply log(x) by itself.

$(d)/(dx)(log(x))^2 \n (d)/(d(log(x)))(log(x))^(2) * (d)/(dx)(log(x)) \n 2log(x) * (1)/(ln(10)x) \n (2log(x))/(ln(10)x)$

In the triangle shown, what is the value of the missing angle?139°

41°

65°

74°

Answers

Because angles in a triangle add up to 180, you can add up the given angles and then take that answer away from 180, so:
65 + 74 = 139
180 - 139 = 41°
So your answer is 41°, I hope this helps!

the answer is 41 degrees

a triangle has 180degrees, is two of the angles add to equal 139 then subtract that from 180 and you get your answer if 41
