Fynjy0 [20]

Answer:The radius of Betelgeuse is about 5 × 1011 meters, and the radius of Venus is about 6 × 106 meters.

Step-by-step explanation:

because the 500 billion Has 11 0s so it will be 5 x 10^11

6,000,000 has 6 0s so it will be 10^6

Find the number of 4-digit numbers that contain at least three even digits.

mylen [45]

Answer:

2625

Step-by-step explanation:

First let's see all the possible combinations.

(Even=E, Odd= O)

1) EEEO

2) EEOE

3) EOEE

4) OEEE

5) EEEE

Now let's see what E and O possibly could be

E = 0, 2, 4, 5, 6 and 8 (5)

O = 1, 3, 5, 7, 9 (5)

Now we are just simply gonna multiply

1) EEEO = 4*5*5*5

2) EEOE = 4*5*5*5

3) EOEE = 4*5*5*5

4) OEEE = 5*5*5*5

5) EEEE = 4*5*5*5

The even contains a 0, so you can't put 0 in, so (5-1=4), there are only 4 digits for the even.

500 times 4 = 2000

5⁴ = 625

2000+625= 2625

Cathy cakes read 22 pages during a 30 minute study hall. How many pages would she read in 45 minutes

Ede4ka [16]

Since your adding on 15 minutes, and half of 30 is 15, you would divide the number of pages she read by 2.. so she can read 11 pages in 15 minutes... so add 11 more and you get 33 pages in 45 minutes

How do you compute the volume of a partially filled cylinder on its side by knowing the height of the fluid on a vertical diamet

34kurt

Solution :

Since, we can measure the height of fluid. Let it be h.

So height of cylinder is double the height i.e. 2h because cylinder is partially filled.

Also, we can also measure diameter. Let it be d.

Now, we know, radius is haft the length of diameter.

So, r = d/2.

Volume of cylinder is given by :

$V =\pi \times radius^2 \times height \\\\V =\pi\times (\dfrac{d}{2})^2 \times 2h\\\\V = \dfrac{ \pi d^2 h}{2}$

Hence, this is the required solution.
