Answer:
74.33
Step-by-step explanation:
We need to figure out the surface area. The formula for surface area is A=2πrh+2πr2
We substitute r with the radius of this cylinder and the h represents the height of this cylinder. The height we can find because we just add the diameters of the tennis balls. So 2.6*3 = 7.8. Then we get the radius, which will just be the radius of a sphere, so 1.3. Then we plug them into the formula, giving us 74.33
Answer:
The least common multiple = 12x
Step-by-step explanation:
The given expression is,
(2+1)/3 + (x-3)/4 = 1/6x
<u>To find the least common multiple</u>
To eliminate the denominator we have to multiply each term by LCM of denominators.
Here, the denominators are, 3, 4 and 6x
LCM ( 3, 4, 6x) = 12x
Therefore the least common multiple in which eliminate the denominator is 12x
Answer:
$153.75
Step-by-step explanation:
$71.75 / 7=$10.25
$10.25 x 15 =$153.75
Answer:
The correct answer is 70.
Step-by-step explanation:
Since they got the same answer we have the equation:
(a + 3)a + 6 = a + 3(a + 6)
a^2 + 3a + 6 = a + 3a + 18
a^2 + 3a - 3a -a + 6 - 18 = 0
a^2 - a - 12 = 0
(a - 4)(a + 3) = 0
So a = 4 or -3.
As a is given as positive we take a = 4.
The correct numerical value =
(4 + 3)( 4 + 6)
= 70.
