Answer:

12.50 x 4 hours = $50

Step-by-step explanation:

It is advisable to pick the hour based form of payment because this gives room for flexibility in terms of time scheduled for the work.

Also, if the hourly based rate of $12.50 is chosen, this means he only have to work for 4 hours to break even with $50 ( 4hours x $12.50 = $50).

Hence, Paul is advised to pick the hourly based payment if he plans to work for more than 4 hours.

Nevertheless, if he plans to work for less than 4 hours, he is advised to go for $50 payment schedule.

The reason for choosing the hourly pay is that $12.50 paid per hour means if he works for 24 hours,the pay will be $12.5×24=$300...

Which means he will surely earn more by working hourly compared to working being paid $50.

The difference between the $50 and the hourly pay is so much that he will rather go for the highest pay.

What is pi and why do we need it
blsea [12.9K]

Answer:

See below

Step-by-step explanation:

π, pronounced as <em>pi</em> is the ratio between 2πr which is circumference to 2r which is diameter.

In word, π is circumference/diameter which has exact value of 3.14159... and it is also an irrational number too.

π is often used to be defined as 3, 3.14 or 22/7 [Keep in mind, these numbers are only approximation.] in some fields. In trigonometry, π is mostly used to refer as <u>π radians</u> or <u>π rad</u> which is equivalent to 180°.

Why do we need it? Because it’s useful in a field that requires rotation. If you notice, figure with circular base will always have π with it, the volume is an example.

In calculus, you need π to do solid of revolution method which is:

\displaystyle \large{V =\pi \int\limits^a_b {[f(x)]^2} \ dx }\\\\\displaystyle \large{V = \pi \int\limits^a_b {[g(y)]^2} \ dy}

In trigonometry, you need it for measurement/angle.  

So anything that’s related to revolution, rotation or related to circle must require π at least.

In general life, you do not use it but this is mostly applied in engineering field and anything related to science that involves with circle or revolve.

Mary McDonald makes mugs in Miami. She makes two sizes of mugs: a small mug that she sells for $2.50 and a large mug that she se
IrinaVladis [17]

Mary McDonald sold 11 small mugs and 10 large mugs.

Step-by-step explanation:

Given,

Total cost of sold cups = $85

Cost of one small cup = $2.50

Cost of one large cup = $5.75

Cups at the start of day = 215

Cups at the end of day = 194

Cups sold = Cups at the start of day - Cups at end of day

Cups sold = 215 - 194 = 21

Let,

x represents the number of small cups.

y represents the number of large cups.

According to given statement;

x+y=21    Eqn 1

2.50x+5.75y=85    Eqn 2

Multiplying Eqn 1 by 2.50

2.50(x+y=21)\\2.50x+2.50y=52.50\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(2.50x+5.75y)-(2.50x+2.50y)=85-52.50\\2.50x+5.75y-2.50x-2.50y=32.50\\3.25y=32.50

Dividing both sides by 3.25

\frac{3.25y}{3.25}=\frac{32.50}{3.25}\\y=10

Putting in Eqn 1

x+10=21\\x=21-10\\x=11

Mary McDonald sold 11 small mugs and 10 large mugs.
