Weighted mean average = ---------------------------
number of brands
value = mean price of computers from Store
#1 * number of brands from store #1 + mean price of computers from store #2 * number of brands from store #2
value = $799.99 * 2 + $679.99 * 4 = $4,319.94
number of brands = 2 + 4 = 6
weighted average = $4,319.94 / 6 = $ 719.99
Answer: option b. $719.99

Answer:
551.7
Step-by-step explanation:
it is the square + the circle
15*25+πr²
375+π(15/2)²
375+π225/4
375+176.625=551.625
The volume of each container is: 25,133 
Given:
height of container (h) = 80 cm
diameter of container (d) = 20 cm
radius = half of diameter = 
of 
Recall:
Volume of a cylinder = 
<em>Substitute the values into the formula:</em>
Therefore, volume of each cylinder is approximately 25,133

Answer:
65 degrees
Step-by-step explanation:
If the angle at the top there is 35 degrees, then the angle directly underneath is also 35 degrees, and the angle of 80 degrees is given, and 80+35=115, and the sum of the angles in a triangle is 180, and so 180-115=65. 65 degrees=x
