Answer: Approximately 96 square feet
======================================================
Work Shown:
1 ft = 30 cm
1 ft = (5*6) cm
1 ft = 5*(6 cm)
1 ft = 5*(1 board width)
1 ft = 5 board widths
12*(1 ft) = 12*(5 board widths)
12 ft = 60 board widths
12 ft = 1 full wall length
The wall is 12 feet horizontally across and 8 feet tall, so its estimated area is 12*8 = 96 square feet approximately. This is approximate because of the fact we used the approximation of 1 ft = 30 cm.

20
Step-by-step explanation:
Answer;
The answer is the second; log ₁₂1/4
Explanation;
From the laws of logarithms, given an expression in the form;
Log ₓ y, where x is the base and y is the number, we can apply the change of base formula to a logarithmic expression to get;
Log y/log x, which are to base 10
Thus; Log₁₂1/4 = log 1/4/ log 12
Answer:
Step-by-step explanation:
speed = 88 km/hr
distance = 500 km
time = distance / speed = 500/88= 125/22 hours
Answer:
From the basics of algebra,
a triangle subtended to the center of a circle from the circumference is always isosceles
since the Central angle is 60 and the triangle is isosceles, the other angles are,
meaning that the triangle is equilateral.
all the other angles are 60.
the radius of the circle is the length of the triangles side,
ie 6cm
