Answer = 14/8
Step by step explanation
2 x 7/8
= (2x7)/8
= 14/8
To find this, turn the word question into an equation.
"One less than" means - 1, which is 1 being subtracted from something.
"half a number" means 1/2x, since 1/2 is half and x is unknown.
"is 12" means = 12, which is something equals 12.
Putting this in order would be 1/2x, then - 1, then = 12.
As an equation, this is 1/2x - 1 = 12.
So the equation is 1/2x - 1 = 12
Now you must find the number by solving this equation.
1/2x - 1 = 12
First, add 1 to both sides.
12 + 1 = 13
1/2x = 13
Now multiply both sides by 2.
This way, x will be isolated since 1/2x • 2 = 1x, and 1x = x.
13 • 2 = 26
x = 26
The number is 26.
Answer:
2.25π square inches [or 7.07 sq. in. rounded to 2 decimal places]
Step-by-step explanation:
The largest circle inscribed in a square would have DIAMETER EQUAL TO THE SIDE LENGTH OF THE SQUARE.
Since diameter is double of radius, we can find the radius to be:
diameter = 3 [side length of square]
radius = 3/2 = 1.5 inches
The area of a circle is πr^2
THus, the largest circle area = πr^2 = π(1.5)^2 = π(2.25) = 2.25π square inches
