The pair of numbers that fall between 72 are 71 and 73.
Answer:
Volume of cone = 130 cm³
Step-by-step explanation:
Given:
Volume of cylinder = 390 cm³
dimensions of cylinder = dimensions of cone
Find:
Volume of cone
Computation:
Volume of cylinder = πr²h
390 = πr²h
124.090909 = r²h
So,
Volume of cone = (1/3)πr²h
Volume of cone = (1/3)(22/7)r²h...........[124.090909 = r²h]
Volume of cone = (1/3)(22/7)(124.090909)
Volume of cone = 130 cm³
Using the equations for tangent and secant lines:
Let the unknown length of the line inside the circle = y
6^2 = 3 x (y+3)
Simplify:
36 = 3y+9
Subtract 9 from both sides:
27 =3y
Divide both sides by 3:
Y = 9
Now add to get x:
X = 9 + 3 = 12
X = 12
<u>Answer:</u>
The Time taken by Elena and Jade to meet up is 2.5 hours
<u>Explanation:</u>
Given,
Elena moves with a speed of 6mph while Jada walks at a speed of 4 mph
Also, Distance can be calculated by the formula
To find out the Total speed, i.e., speed of both Elena and Jada as both of them are walking in opposite direction we should add the speed of both the persons, if in same direction we should subtract the values
Here it will be: 
= 10mph
Distance apart is given as 25 miles. Substituting the values,
25 = 
Time = 25/10
Time = 2.5 hour
Hence, It will take 2.5 hours to meet up.
For the first problem the equation should be 2w-1
I also did this quickly in my head but it's most likely correct.
