Emily meal cost 32.75 and Darren's meal cost 39.88 . Emily treats Darren by paying for both meals,and leaves 14% tip. Find the t

tia_tia [17]

32.75 + 39.88 = 72.63

72.63 x 114% = 72.63 x 1.14 = $82.7982 or $82.80 to the nearest cent.

114% is all of the cost of the meal plus 14 % extra for the tip. See how muliplying by 1.14 includes the $72.63 (this saves the step of adding it on at the end if you were only to find 14% of $72.63)

A 12 foot board rests against the wall. The angle that the board makes with the ground is 60 degrees. How far is the base of the

9966 [12]

Answer:

6 foot

Step-by-step explanation:

Since the board is 12foot and the angle makes 60 degrees to the wall, we can assume that it is the 30,60,90 degreees. 30,60,90 degrees triangle makes the side of x, 2x ,and xroot3.

Hence, the board(12foot) is equal to 2x.

andrew11 [14]

From the shaded diagram, Raphael will need 3 of the 6 equal portions, or exactly 1/2 of the area of the circle. Given a radius of 12 ft, knowing that the area of any given circle is $\pi r^2$ , and knowing that the area of the fabric needs to be half of the total area, we can set up the equation for the area of the fabric $A$ :

$A= \frac{1}{2}\pi (12)^2$

Simplifying, we find that the area of the fabric is exactly

$\frac{1}{2} \pi (144)= \frac{144}{2} \pi=72\pi$ ft.² Using the approximation of 3.14 for π, we get an area of approximately $72(3.14)=226.08$ ft² of fabric.

Ludmilka [50]

Answer: 370 liters

Step-by-step explanation:

Given : Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 8 liters of natural oil for every 5 liters of synthetic oil.

Then , the amount of Petrolyn oil made by above composition = $8+5=13\text{ liters}$

Also, the amount of petrolyn oil is proportional to the amount of synthetic oil.

Let x be the amount of synthetic oil need ot make 962 liters of Petrolyn oil, the we have the following equation:-

$\dfrac{x}{962}=\dfrac{5}{13}\\\\\Rightarrow\ x=\dfrac{5\times962}{13}=370$

Hence, In order to make 962 liters of Petrolyn oil, 370 liters of synthetic oil is needed .
