As what I can observe, the pathway can be formed with 2 right triangles. Thus, I'll get the area of the 2 right triangles and multiply its area by the paving cost per square meter.
Area of Right Triangle: ab / 2
a = 6 2/3 m ⇒ 20/3 m; b = 3m
Area of 1 triangle= (20/3 m * 3 m) ÷ 2 = 20 ÷ 2 = 10 m²
Area of 2 triangles = 10m² * 2 = 20 m²
Total cost = $40 * 20m² = $800
Answer:
m = 5
Step-by-step explanation:
200m - 125m + 48,750 = 50,000 - 175m
=> 75m + 48,750 = 50,000 - 175m
=> 75m + 175m = 50,000 - 48,750
=> 250m = 1250
=> m = 5
Hoped this helped.
Formula C= 2(3.14)(R)
We are looking for R first, so
=
——
2
r= 25.12
————
2(3.14)
r= 25.12
———-
6.28
r= 4
diameter= r(2)
4(2)= 8
THE DIAMETER OF THE CIRCLE IS 8
Answer:
No.
It's x^4 - 4x^3 + 7x^2 - 28x.
Step-by-step explanation:
(x - √7 i)(x +√7i)
= x^2 + √7x i - √7x i - 7 i^2
= x^2 - 7 * -1
= x^2 + 7
g(x) = x(x - 4)(x^2 + 7)
= x(x^3 + 7x - 4x^2 - 28)
= x^4 - 4x^3 + 7x^2 - 28x.
