The question is ambiguous.

A is right if the second hour is in terms of the original amount (16 grams). That is not how it should be done, but there is nothing in the problem restricting us from doing it that way.

B is right the way most people would do the problem. I would say you should accept this as the right answer. The 4.5% is taken away from what was left after the first hour. I would do it that way left to my own devices.

C. The % conversions are not correct. Those conversions are 35% and 45%
C is not even in contention for being right.

D Same problem as C

Wyatt uses 3.15 cups of flour in a recipe that makes 9 shortcakes. Cora uses 2.4 cups of flour in a recipe that makes 8 shortcak
dalvyx [7]
For Wyatt's recipe the rate is:
 r1 = 3.15 / 9
 r1 = 0.35
 For Cora's recipe the rate is:
 r2 = 2.4 / 8
 r2 = 0.3
 The difference between both recipes is:
 r1-r2 = 0.35 - 0.3 = 0.05
 Answer:
 
0.05 cups of flour per shortcake less is needed for Cora's recipe

A manufacturing company has the following fixed monthly costs and unit variable costs: Rent = $2,200 Utilities = $375 Variable c
valentinak56 [21]

A manufacturing company has the following fixed monthly costs and unit variable costs:

Rent = $2,200

Utilities = $375

Variable costs for materials and assembly = $13.25/unit

Monthly labor = $750

Given is the product is sold at $24.99 per unit

Let the number of units sold be x

Adding total cost = 2200+375+750=3325

Equation becomes:

3325+13.25x=24.99x

11.74x=3325

x= 283.21

So, rounding it to nearest whole number we get, 283 units.

A triangle has side lengths of 7 in., 9 in., and 11 in. Determine whether this is a right triangle and why.
Harlamova29_29 [7]

Answer:

Not a right triangle.  See below for my reasoning.


Step-by-step explanation:

If this is a right triangle, then the sum of the squares of the two shorter sides will equal the square of the longest side:  7^2 + 9^2 = 11^2 => 49 + 81 = 121   But this is false.
