Answer:
The answer is
A. 529.66 ft²
Step-by-step explanation:
The picture of the composite figure is not given,
But find attached the figure.
The composite consists of two solid shapes
1. Cylinder
2. Rectangular prism
To solve for the total surface area of the composite
Let us solve for the total surface area of the cylinder
Given radius r= 4ft
Height h=5ft
A= πr²+2πrh-πr²
N/B we subtracted the second circular surface since it is joined to the rectangular prism
A= 3.142*4²+2(3.142)*4*5-3.142*4²
A= 50.272+125.68-50.272
A=125.68ft²
We proceed to find the area of the rectangular prism
We know that the prism has 6 sides
Hence area
A= 2(11*6)+ 2(8*6)+2(11*8)
A= 132+96+176
A= 404ft²
Hence total surface area is
404+125.68= 529.68ft²
if x is the bigger num and y is the smaller
x + y = 91
x - 3y = 7.7
multiply by -1
x+y = 91
-x + 3y = -7.7
add the equations
4y = 91 - 7.7
4y = 83.3
y = 20.825
then x+y = 91 use to find x
x+20.825 = 91
x = 70.175
the two numbers are 70.175 and 20.825
Answer: Choice B
Coffee Brand A is a better buy because its unit rate is $0.44 per ounce
=======================================================
Explanation:
Brand A is sold for $6.99 per pound, which is the same as saying $6.99 per 16 ounces. The unit rate is 6.99/16 = 0.436875 = 0.44 dollars per ounce
Brand B is sold for $5.69 for 12 ounces. The unit rate is 5.69/12 = 0.47416 = 0.47 dollars per ounce
Brand A is cheaper per ounce compared to brand B.
------------------
Here's another way we can look at it
Brand A is $6.99 per 16 ounces. We can set up the equation below
6.99 dollars = 16 ounces
then divide both sides by 16 to turn "16 ounces" into "1 ounce"
So,
6.99 dollars = 16 ounces
6.99/16 dollars = 16/16 ounces
0.436875 dollars = 1 ounce
0.44 dollars = 1 ounce
is the unit rate for brand A.
Similar steps would happen with brand B as well.
