Least common multiple of 0.99 and 1.35 
99 = 3 x 3 x 11
135 = 3 x 3 x 3 x 5

LCM = 3 x 3 x 3 x 5 x 11 = 1485.
Thus LCM of 0.99 and 1.35 = 14.85

Therefore, the least number of brownies he must have sold = 14.85/0.99 = 15.

Answer:

17662.5 sq. feet

Step-by-step explanation:

We know that the formula for Area of a Circle is A = \pi (r)^2.

r = radius; d = diameter, which is r*2


And so, in the question, it gives you that the diameter is 150, first we divide it by 2 to get the radius.

150/2 = 75

The question said to keep \pi =3.14, so then we plug in the equation-

A = 3.14 * 75^2


Then we use PEMDAS [Parenthesis; Exponents; Multiply & Divide; Add & Subtract] which would get us-

A = 3.14 * 5625 (first doing the Exponent)

And we continue-

A = 17662.5 (then multiple)

So our answer is-

17662.5 sq. feet

I hope this helps!
Please give brainliest!

Have a great day

Just solve the equation 5-√x = 3

So, let’s solve it:

5-√x = 3 ⇔ 5-3=√x ⇔ √x = 2 ⇔ x=4

Then ?=4
