2 feet per year. Its rise over run so you look for when the line perfectly intersects the end of a box and that happens every time you go up by 2 and across by one
Answer:
a = 15
Step-by-step explanation:
First, you have to combine like terms: 5a and 3a, -5, -15, 6, and 4.
You can do it in any order and you will always get a = 15 for your answer.
Hope this helps!!!
So you would first find the length of y.
To do that, use the Pythagorean's Theorem:
a²+b²=c²
in this case, c = 3, and b = 1.
a² + 1² = 3²
a² + 1 = 9
a² = 8
a = √8
Now to find z, use the Pythagorean's Theorem again:
a² + b² = c²
where √8 = a and 8 = b, and z = c.
√8² + 8² = z²
8 + 64 = z²
72 = z²
z = √72
To simplify this, take out the largest perfect square, or 36:
z = √36√2
z = 6√2
So your answer would be B.

Answer:
- 113.0 cm²
- 2464.0 in²
- 95.0 ft²
Step-by-step explanation:
1. The area of a circle is given by the formula ...
A = πr² . . . . . where r is the radius
The radius is shown as 6 cm, so the area is ...
A = (3.14)(6 cm)² = 113.0 cm²
__
2. The radius is shown as 28 in. We note that this is a number divisible by 7, so we choose 22/7 for π.
A = (22/7)(28 in)² = 2464 in² . . . . see comment
__
3. The radius is half the diameter, so is 11/2 = 5.5 ft. Then the area is ...
A = (3.14)(5.5 ft)² = 95.0 ft²
_____
<em>Additional comment</em>
If you use a more exact value of π for problem 2, the area is 2463.0 in². If you use 3.14 as the value of π, the area rounds to 2461.8 in². For these values of pi (3.14 or 22/7), the answer is only good to about 3 significant digits. 2464 has more significant digits, so digits beyond the first 3 may be in error.
Answer:
70.622 in³
Step-by-step explanation:
Volume of cylinder = 
= (3.14)(2.1^2)(5.1)
= 70.622 in³
