Answer:
The answer to your question is SA = 2419.34 m²
Step-by-step explanation:
Data
a = 11.42 m
side = 11 m
height = 20 m
Formula
SA = 2B + PH
Process
1.- Calculate P
Perimeter = P
P = 7(11)
= 77 m
2.- Calculate B
B = Pa/2
= (77)(11.42)/2
= 879.34/2
= 439.67 m²
3.- Calculate 2B
2B = 2(439.67)
= 879.34 m²
4.- Calculate PH
PH = (77)(20)
= 1540 m²
5.- Calculate SA
SA = 879.34 + 1540
= 2419.34 m²
A cube has equal sides if they are 2÷ 1/2 each then L×W×H would be (2÷ 1/2)^3. To divide fractions we multiply the reciprocal.
2÷ 1/2 = 2/1 × 2/1 = 4
4×4 = 16×4= 64
answer is V = 64 inches cubed.
Let the women's height be AE and distance between the women and tower be AC.
Also let the height of tower be BC.
Now, clearly it is forming a triangle.
So, in triangle ABC,
Hence, BC = 59.5m
So, BD(total height of the tower)
Therefore, total height of the tower =

Answer:
This means that for (x-6)(x+3) to be positive, the value of x has to be greater than 6; x>6
Step-by-step explanation:
Step 1
Given the equation;
(x-6)(x+3)
Step 2
To determine the values of x that make the equation positive, the equation can be expressed as;
(x-6)(x+3)>0
x-6>0/(x+3)
x-6>0
x>0+6
x>6
This means that for (x-6)(x+3) to be positive, the value of x has to be greater than 6; x>6
One is false, two is true. Hope I helped
