Answer:
<h2>
A = 88 m²</h2>
Step-by-step explanation:
The area of the figure is a sum of:
the area of the rectangle:
4 m × 12 m = 48 m²
and the area of the triangle:
¹/₂ × (6 + 4 + 6) m × 5 m = 40 m²
Therefore, area of the firgure:
A = 48 m² + 40 m² = 88 m²
Answer: x=2 - 1/2 x ㏒(16/2953125)
Step-by-step explanation:
- log (28^2) + log(525^-3) + 2x=log(10^4)
- log(28^2 x 1/523^3) + 2x=4
- log(28^2/525^3) + 2x=4
- log (112/75 x 75 x 525) + 2x=4
- log(16/2953125) + 2x=4
- 2x=4-log(16/2953125)
- <u><em>x=2-1/2 x log(16/2953125)</em></u>
Answer:
1100 cookies
Step-by-step explanation:
There are 3 types of cookies, the first represents 45% of the total, the second 25% and the last type there are 330. We can pose the following equation:
0.45 * x + 0.25 * x + 330 = x
solving for x:
x - 0.45 * x - 0.25 * x = 330
0.30 * x = 330
x = 330 / 0.3
x = 1100
which means that there are a total of 1100 cookies
