Answer:
surface area: 7241.25
Step-by-step explanation:
using this formula for surface area of cyclinder: 2πrh+2π
diameter = 2r --> 39.2 = 2r
so r= 19.6
To solve an equation for x we will try to isolate x. Hence, first step is to use the distributive property. Therefore,
4x + 29 = 5 - 8(x+6)
4x + 29 = 5 - 8x - 48
4x + 29 = - 43 -8x Combine the like terms.
4x + 29 + 8x = -43 Add 8x to each sides of the equation.
12x + 29 = -43
12x = -43 - 29 Subtract 29 from each sides.
12x = -72

So, x =- 6

Answer:</h2>
B. 12/5
<h2>
Step-by-step explanation:</h2>
In a division, we should swap the second fraction and change the equation to times. After that, we can multiply each fraction easily.
4/5 : 1/3
= 4/5 x 3/1
= 12/5
In conclusion, the simplified quotient of 4/5 : 1/3 is 12/5
Answer:
20
Step-by-step explanation:
This triangle can be solved using the Pythagorean theorem. 16^2+12^2=x^2. 16^2+12^2=400. If we set 400 equal to x^2, x=20.
Answer: Division
Divide both sides by 75 to isolate N
