Answer:
1) a = 0
Step-by-step explanation:
Taking logarithms base 2, we have ...
-3a·log2(1/8) = 3a·log2(512)
-3a(-3) = 3a(9)
27a -9a = 0 . . . . . . . subtract 9a
a = 0/18 = 0 . . . . . . divide by 18
The solution is a = 0.
Answer:

Step-by-step explanation:
Assuming this pizza is a circle, we can use this formula for area:

1. Find Radius
We are given the diameter: 12 inches, but the formula uses radius.
The radius is half the diameter, or:



2. Calculate Area
Substitute the radius (6 inches) in for r. The question also asks us to use 3.14 for pi.

Solve the exponent.
- (6 in)²= 6 in* 6 in= 36 in²

Multiply.

3. Round
The question asks us to round to the nearest tenth.
The 4 in the hundredth place tells us to leave the 0 in the tenth place.

The area of the pizza is about 113.0 square inches.

Answer:
x° = 83°
Step-by-step explanation:
All angles in a triangle (any kind of triangle: right, isosceles, equilateral etc.) add up to 180 degrees.
So, if we are given the ABC triangle, then:
angle A + angle B + angle C = 180°
In this particular case, we are given values of two angles, so using the previous relation, we can write:
x° + 44° + 53° = 180°
Now, it's easy to find x°:
x° = 180° - 44° - 53°
x° = 83°
