EXPLAIN What is the quotient when 1,000,000,000 is divided by 28x 57
Rama09 [41]

Answer:

626,566.42

Step-by-step explanation:

The quotient is answer of a value divided by another value. In this problem we have a value of 1,000,000,000 divided by the product of 28 x 57.

This can be represented like this:

Total=\dfrac{1,000,000,000}{28*57}

Total=\dfrac{1,000,000,000}{1,596}

Total=626,566.42

The fraction can also be used to indicate a number being divided by another number.

Need emergency help and want correct answers with explanation
fenix001 [56]

Answer:

250 degrees

Step-by-step explanation:

The arc intercepted by the angle formed by a secant and a tangent is twice the measure of the angle. See the attached image.  The intercepted arc measures 110 degrees.

x is the measure of the rest of the circle, so it is 360 - 110 = 250 degrees.
