Answer:48.6
we know that
You can paint 75 square feet of a surface every 45 minutes
so
using proportion
Find out how long it takes you to paint a surface area of 81 square feet
45(81)/75=48.6
hope this helped and I hope you get a correct answer :D
Answer:
4 45/100 Keep simplifying it. You can do it!
Step-by-step explanation:
4 is the whole. 45 is out of 100
To find the hypotenuse of a right triangle you can use the Pythagorean theorem. (a² + b² = c²) Using the measurements provided we can solve like this.
Both a² & b² = 7²
7 x 7 = 49
49 + 49 = 98
Now we need to find the square root of 98 (c²) to get our answer.
9.9 x 9.9 = 98.01 or about 98
The measurements for the tirangle are 7 units, 7 units, and 9.9 units.
Hope this helps!
Answer:
A)100 in
Step-by-step explanation:
Given: Radius of circular table= 16 inches
Now, solving for circumference of the tabletop.
Remember, circumference of circle= 
we know pi= 3.14
∴ Circumference= 
⇒ Circumference of circular tabletop= 100.48 in ≅ 
∴ Circumference of circular tabletop is 100 in.
