Mikasi and Julie are determining which size sports drink is the better buy per ounce: a 16-ounce bottle for $1.95 or a 36 ounce bottle for $3.05. Who is correct? Explain.Mikas: 16-oz bottle: 12.2¢ per ounce
36-oz bottle: 8.5¢ per ounce

Julie: 16-oz bottle : 8.2¢ per ounce
36-oz bottle: 11.8¢ per ounce

Answers

Answer 1

Answer: The answer is
Mikas: 16-oz bottle: 12.2¢ per ounce
36-oz bottle: 8.5¢ per ounce

To calculate price per ounce, we will use the proportion:
16 ounces : $1.95 = 1 ounce : x
Crossing the products:
x = $1.95 × 1 ounce ÷ 16 ounces
x = $0.122 = 12.2¢
So, 16-oz bottle is 12.2¢ per ounce.

Similarly:
36 ounces : $3.05 = 1 ounce : x
Crossing the products:
x = $3.05 × 1 ounce ÷ 36 ounces
x = 0.085 = 8.5¢
So, 36-oz bottle is 8.5¢ per ounce.

It can be concluded that Mikas was correct.

815 x 360 = 293,400 gal per second.

293,400 gal ÷ 4 quarts = 73,350 quarts per sec.

Carla must ice a german chocolate cake. The diameter of the cake is 6 cm. Use the formula A = 3.14 x r2 to find the area of the cake. A) 7.07

B) 19.63
Eliminate

C) 20.56

D) 28.26

Answers

Diameter = 6 6/2 = 3
Radius = 3 3 to the power of 2 = 9
A = (3.14)(9) = 28.26

The radius(r) is half the diameter. So just plug 3 into the equation A=πr². A=3π². The area is about 29.60 (which I think you meant to write for D).

Write and equation of a line that is parallel to the line below and passes through the given point

Answers

a line parrelel would have the same slope

in y=mx+b m=slope and b=yintercept

so y=-2/3x-5
the point you want is -3,11 or this equation is true when x=-3 and y=11 are true so subsitute and solve for the new 'b'

11=-2/3(-3)+b
11=2+b
subtract 2 from both sides
9=b

the equaqtion is y=-2/3x+9

If one line is parallel to another, that means the two lines have the same slope. Therefore, since the line you are creating is parallel to the line y = -2/3x - 5, it's slope must be the same, -2/3. Additionally, you know it passes through the point (-3, 11).

If you don't remember the slope-intercept equation, it looks like this:
y = mx + b, where m is the slope, b is the y-intercept, and x and y are, well, x and y.

Let's plug in the slope we know it must have (-2/3) and plug in the (x, y) coordinates we were provided so that we can find b.
11 = -2/3(-3) + b

Solve for b:
11 = 2 + b
9 = b

Now we know our slope and our y-intercept, after solving for it, so we can write our final equation!

The answer is: y = -2/3x + 9
