Answer:
8 hours
Step-by-step explanation:
11 hours = $176
⇒ 1 hour = $176 ÷ 11 = $16
To determine how many hours she would have to work to make $128, divide $128 by $16:
⇒ number of hours = $128 ÷ $16
= 8 hours
I think the answer is A,C,F
Answer:5 sqrt(2)
Step-by-step explanation:
All the sides of the square are congruent by the markings. Therefore they all measure 5 and because all 4 sides are congruent it is a square. Because it is a square the corners are right angles and you can use the Pythagorean Theorem. a^2 +b^2 = c^2.
5^2 + 5^2 = x^2
25 + 25 = x^2
50= x^2
X = square root of 50
X= square root of 25 Times Square root of 2
X= 5square root of 2
Answer:
Step-by-step explanation:
To find the surface area of the cylinder you must apply the following proccedure:
- Calculate the surface area of the circles. They are equal, then you can multiply the surface area of a circle by 2:
Where r is the radius.
- Calculate the surface area of the rectangle:
Where l is the lenght and w is the width.
(The length is the circumference of the circle)
Then:
- Add the areas obtained.
The result is:
Answer:
the domain is: 0,-3,4,2,-2.
