Answer:
39.25 cm
Step-by-step explanation:
The formula for a circle is pi x radius x radius.
So to get the radius, you multiply 10 and 1/2. You should get 5. Then you multiply 5 by 5. You should get 25.
Then you multiply 3.14 and 25. You should get 78.5.
The last step is to divide 2 by 78.5. You should get 39.25
Answer:
A) By using the Pythagorean Theorem, we will see that 
. If we simplify it, we will find that the hypotenuse of Δ
B) approximately 
Step-by-step explanation:
A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!
***Pythagorean Theorem is 
B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, 
.
≈
Hope you do well on the rest of your math problems :D
Answer:
$84.48
Step-by-step explanation:
Multiply the price before discount by 1.2 (100% + 20%) to get 70.40 x 1.2 = 80.48; $80.48

<span>1. What is 1/6 plus 2/6?
1/6 + 2/6 = 3/6 =1/2
2. What is 4/8 plus 1/8?
4/8 + 1/8 = 5/8
3. What is 2/3 plus 2/3?
2/3 + 2/3 = 4/3 = 1 1/3</span>
So the proportion would go as follows
5.5. 7.5
=
4.5. 60
To solve this you just cross muliply and divide.
I hope this helps you
