In this case, you first need to think about what is the formula for the circumference of a circle. The formula for the circumference of a circle is 2 * PI * r, where r is the radius of the circle, and PI is the mathematical constant approximately equal to 3.14.

$2\pi*r=2*3,14*2=12,56$ feet

Robert types 152 words per minute. How long will it take Robert to type 2,508 words?

Novay_Z [31]

2,508 divided by 152 is equal to 16.5
I say 17 minutes, since 152x16=2,432 so a extra minute is needed to get to 2,508

If m < A = 4x + 12 and x = 15, is < A acute, obtuse, or right? Justify your answer.

BlackZzzverrR [31]

Step-by-step explanation:

Angle A = 4x + 12 = 4(15) + 12 = 72°.

Acute is for angles that are less than 90°.

Obtuse is for angles that are between 90° and 180°, not inclusive.

Right is for angles that are 90°

Hence the answer is acute.
