Answer: Solve for m m by simplifying both sides of the equation, then isolating the variable. m=15
Step-by-step explanation: Reducing to lowest terms On both sides
Let x be the time required to do the job when they work together.
1/x = 1/9 + 1/10 = 19/90
x = 90/19 = 4.7 hours
The answer that you’re looking for is B
The nearest whole number the diameter of the circle is 5.0 cm.
<u>Given the following data:</u>
- Circumference of a circle = 15.4 cm
To estimate to the nearest whole number the diameter of the circle:
In this exercise, you're required to solve for the diameter of a circle and round up its value to the nearest whole number.
<h3>How to calculate the circumference of a circle.</h3>
Mathematically, the circumference of a circle is given by the formula:

<u>Where:</u>
- D is the diameter of a circle.
Making D the subject of formula, we have:

Substituting the given parameters into the formula, we have;

D = 4.90 cm
To the nearest whole number:
D = 4.90 ≈ 5.0 cm
