Answer: 1/2
<u>Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD</u>
(2/12*1/1) + (1/3+4/4)
<u>Complete the multiplication and the equation becomes
</u>
2/12+4/12
<u>The two fractions now have like denominators so you can add the numerators.</u>
2+4/12 = 6/12
<u>This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor </u>
6/12 ÷ 6/6 = 1/2
<u>Therefore:
</u>
2/12 + 1/3 = 1/2
Answer:
96π
Step-by-step explanation:
You will need the formula for the volume of a cone.
π
h
r= 6 cm
To find the height, you need to use the Pythagorean theorem.
a²+ b² = c² (a and b are the 2 legs and c is the hypotenuse)
b = 
b= 
= 8
h= 8 cm
remember PEMDAS!
π
8
π(36)8
π(12)8
V= 96π
Answering in terms of π is more accurate because it is actually infinite so when it gets rounded to 3.14, that is only an approximation of pi. (π is actually 3.1415926535897932384626433 etc.)
B. Divide the next number by four and just reverse the sign.
Answer:
The answer to your question is 37.5
Answer:
21
Step-by-step explanation:
- AC = 64
- AB = 7x + 8
- BC = 3x + 6
<u>Since AC = AB + BC</u>
- 7x + 8 + 3x + 6 = 64
- 10x + 14 = 64
- 10x = 50
- x = 50/10
- x = 5
------------------
BC = 3x + 6 = 3*5 + 6 = 21
