The answer is 22 minutes:
20x for Tatsu and 10x for Andy
30x = 11
x = 11/30
11/30 * 60 = 22
Answer:
x=17
Step-by-step explanation:
This should be for a "kite": AD=DC, AB=BC and ∠A=∠C
8x-27 = 3x+58
5x = 85
x = 17
The amounts for each donut are given as follows:
<h3>How to obtain the amounts?</h3>
The amounts for each donut are found applying the proportion, multiplying the decimal equivalent of each percentage by the total number of donuts.
From the problem, the total number of donuts is given as follows:
100 donuts.
The percentages of each type of donuts are given as follows:
The decimal equivalent of each percentage is given as follows:
Hence the amounts are given as follows:
- Strawberry: 15, as 0.15 x 100 = 15.
- Chocolate: 45, as 0.45 x 100 = 45.
- Sprinkle: 40, as 0.4 x 100 = 40.

Answer:
Length: 5 ft; width: 4 ft.
Step-by-step explanation:
A = LW formula for area of rectangle
(2x + 1)(2x) = 20 substitute length, width, and area into formula
4x² + 2x - 20 = 0 use the distributive property to multiply out left side
2x² + x - 10 = 0 divide both sides of equation by 2
(2x + 5)(x - 2) = 0 factor out trinomial
2x + 5 = 0 or x - 2 = 0 use zero product rule to solve for x
2x = -5 or x = 2 subtract 5 from both sides; add 2 to both sides
x = -5/2 or x = 2
We discard x = -5/2 since it would give negative length and width, and the length and width cannot be negative.
Length: 2x + 1 = 2(2) + 1 = 5
Width: 2x = 2(2) = 4
Length: 5 ft; width: 4 ft.
