Anything to a negative power makes it inverse and 1/2 power is just square root.
Therefore 49^-1/2 is 1 divided by the square root of 49. The square root of 49 is 7 so the answer is 1/7.
Answer:
The area of the cover for the hot tub must be:
Step-by-step explanation:
First, you must understand that since a hydromassage tub is mentioned and the diameter, it is assimilated that it is round in its upper part, which is why the formula is used to find the area of a circle:
- <u>Area of a circle = pi * radius ^ 2</u> (you must know that the radius is half the diameter)
Since the diameter is mentioned, it can be replaced in the formula:
- Area of a circle = 3.14 * (3.5 feet) ^ 2
- <u>Area of a circle = 38,465 square feet. Approximately 38 square feet</u>.
Hello!
To find the minimum number of weeks Jakob will need to wait if he saved 35 dollars per week, we would need to create an inequality equation.
Since he needs to save at least 700 dollars, it can be represented by the the greater than or equal to symbol. Also, the variable x, will be used in this equation representing the number of weeks. Then, we can create an equation for this problem.
35x + 175 ≥ 700 (subtract 175 from both sides)
35x ≥ 525 (divide both sides by 35)
x ≥ 15
Therefore, Jakob will have to wait a minimum of 15 weeks in order to save at least 700 dollars for a new computer.
Right angles will be formed because in drawing
the perpendicular lines they all form right angles
to begin with. With several more draw it will
still be the same as if you are drawing one
the answer is -right angles
