Answer:

$5 \times 108 - 3.4 \times 108$

lets take 108 as X

$5x - 3.4x = 2x \\ \\ 1.6x = 108 \times 1.6\\ = 172.8$

Answer:

The answer is x = 8/5

Step-by-step explanation:

6 - 5x + 2 = 3x - 12 + 2x

4 - 5x = 5x - 12

4 = 10x - 12

16 = 10x

8/5 = x

The height of a right circular cylinder is 1.5 times the radius of the base. What is the ratio of the total surface area to the

Naily [24]

Let r represent the radius of cylinder.

We have been given that the height of a right circular cylinder is 1.5 times the radius of the base. So the height of the cylinder would be $1.5r$ .

We will use lateral surface area of pyramid to solve our given problem.

$LSA=2\pi r h$ , where,

LSA = Lateral surface area of pyramid,

r = Radius,

h = height.

Upon substituting our given values in above formula, we will get:

$LSA=2\pi r\cdot (1.5)r$

Now we will find the total surface area of cylinder.

$TSA=2\pi r(r+h)$

$TSA=2\pi r(r+1.5r)$

$TSA=2\pi r(2.5r)$

$\frac{TSA}{LSA}=\frac{2\pi r(2.5r)}{2\pi r(1.5r)}$

$\frac{TSA}{LSA}=\frac{2.5r}{1.5r}$

$\frac{TSA}{LSA}=\frac{25}{15}$

$\frac{TSA}{LSA}=\frac{5}{3}$

Therefore, the ratio of total surface area to lateral surface area is $5:3$ .

Mila has biked 10 miles in 1.5 hours if Mila continues at the same rate,how many miles will she bike in 3 and a 1/2 hours?

Viefleur [7K]

Mike biked 10 miles in 1.5 hours. Mila bikes at the same rate too.

Therefore, she will bike x miles in 3.5 hours

(10/1.5) = (x/3.5)

You cross multiply

1.5x = 10 x 3.5

1.5x = 35

x = 35/1.5

x = 23 miles (approximately)

I hope this helps

How do I find the closet length

Sophie [7]

Add the vertical distance between VU and the horizontal distance between UT and get the square root of what you added. That should be the answer.
