Prove that the value of the expression (2^10+2^8)(2^5-2^3) is divisible by 60
I WILL MARK BRAINLIEST!!!!!!1
Should be written like __*60
Fill in the blank

Answers

Let's simplify it, because if we do, we can find the value and then deduce whether it is divisible by 60.

2^10 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2

2^10 = 1,024

2^8 = 256

2^5 = 32

2^3 = 8

Substitute the expressions in the equation for their values...

(1,024+256)(32-8)

Simplify...

(1,280)(24)

Simplify...

30,720

Now, divide it by 60...

512 * 60 = 30,720

512*60=(2^10+2^8)(2^5-2^3)

I'll do #1 & #2, but you have to do the rest on your own, I'm sorry.

#1 Answer:

The median height of giraffes is:

18 feet.

Step-by-step explanation:

We are given height, in feet, of 9 giraffes as:

           18, 16, 22, 14, 17, 19, 15 ,19,22

Now to find the median height of giraffes in the zoo we need to arrange the given data set in ascending order as:

14     15     16   17    18     19    19    22    22

Now we know that median is the central tendency of the data i..e it lie in the middle of the data set.

The value that lie in the middle of the given data set is:

18.

Hence, the median height of giraffes is:

18 feet.

#2 Answer:

The median of the sizes of the four parks is:

                        Option: C    33 acres.

Step-by-step explanation:

We are given area of four parks as:

27 acres    30 acres      34 acres      49 acres.

We know that the median of a data is the central tendency of a data and always lie in between or middle of the data set.

Hence, here the median will lie between 30 and 34

and hence is calculated as:

[tex]Median = \frac{30+34}{2}[/tex]

[tex]Median = \frac{64}{2}[/tex]

[tex]Median = 32[/tex]

which is close to 33.

Hence, the median size of the park is:

                             33 acres.

A local carnival sells two different containers of popcorn, as shown below.


Both containers have the same height, and the bases of the containers are congruent. Which statement best describes the relationship between the volumes of the two containers?

A. Container B will hold twice the volume of popcorn of Container A.
B. Container B will hold three times the volume of popcorn of Container A.
C. Container B will hold the same volume of popcorn as Container A.
D. Container B will hold 1/3 times the volume of popcorn of Container A.

The answer would be C since the formula for volume is lwh or bh. With this info, you know that the bases are congruent which means they are the same, as well with the height. So you just multiply the height by the base and they should be the same.
