Two circular cylinders are similar. The ratio of the areas of their bases is 9:4. Find the ratio of the volumes of the similar s
OleMash [197]

Answer:

27 : 8

Step-by-step explanation:

Given 2 similar figures with ratio of sides a : b, then

ratio of areas = a² : b² and

ratio of volumes = a³ : b³

Here the ratio of areas = 9 : 4, thus

ratio of sides = \sqrt{9} : \sqrt{4} = 3 : 2

ratio of volumes = 3³ : 2³ = 27 : 8

Parallel lines e and f are cut by transversal b what is the value of x?
NikAS [45]

Answer: 25

Step-by-step explanation:

Both lines are being cut by the same transversal so to solve for x, make both equations equal to each other

2x+10 = 3x-15

To isolate x, do the inverse operations (for any side chosen)

Do the inverse operations to move -15 and isolate 3x

Add 15 to 10 (10+15=25)

You now have 2x+25=3x

Now, do the same to combine the x values together

25=3x-2x

You now have 25=1x

Divide by 1 on both sides

25=x

A factory produces bottled water at a rate of 2,000 cases per hour. They know that 1.14% of the cases must be rejected because a
IRINA_888 [86]
1.14 per 100 or 1.14:100 or \frac{1.14}{100}

\frac{1.14}{100} =  \frac{n}{2000}

I will multiply the numerator by 20 because multiplying by 20 is how 100 became 2000
22.8 cases are rejected per hour.
