Given

There are 12 sophomores

8 Juniors

and 13 seniors

Ms. bell create a 4- member committee  of seniors

No of ways of selecting 4 seniors out of 13

=^{13}C_4

=\frac{13!}{9!4!}

=\frac{13\times 12\times 11\times 10}{4\times 3\times 2\times 1}

=715

So, there are 715 ways of forming a 4 member senior committee.

Find the surface area of the right rectangular prism shown below.<br> units?<br> 2.5<br> -
Mrrafil [7]

Answer: Surface area = 46 units²

Step-by-step explanation:

The formula for determining the total surface area of a rectangular prism is expressed as

Surface area = 2LW + 2LH + 2WH

Where

L represents the length of the rectangular prism.

W represents the width of the rectangular prism.

H represents the height of the rectangular prism.

Looking at the diagram,

L = 4 units

W = 2.5 units

H = 2 units

Therefore,

Surface area = (2 × 4 × 2.5) + (2 × 4 × 2) + (2 × 2.5 × 2)

= 20 + 16 + 10

= 46 units²

If a cube with the length of the side of 4 cm is cut into smaller cubes with the length of the side of 1 cm, then what is the pe
ValentinkaMS [17]

Answer:

300 %

Step-by-step explanation:

Length of the larger cube =4 cm

So volume V=side^3=4^3=64cm^3

Length of the smaller cube = 1 cm

Volume of the smaller cube V=side^3=1^3=1cm^3

So total number of smaller cube =\frac{64}{1}=64

Surface area of the larger cube A=6\times side^2=6\times 4^2=144cm^2

Surface area of the 64 smaller cube A=64\times 6\times side^2=64\times 6\times 1^2=384cm^2

So percentage increase in surface area =\frac{384-96}{96}\times 100=300 %

A student’s work to simplify and combine radicals is shown below. Select the statement which best applies to the sample mathemat
jeka94
Your answer is incorrect. You forgot to get the square root of 25 and 4. Answer should be 16√2

we can only subtract radicals that are the same. At first glance, 4√50 - 2√8 are not the same, so they are not likely to be subtracted. However, each radical can still be simplified.

4 √50 = 4 √25 * 2 = 4 * 5 √2 = 20 √2
2 √8   = 2 √4 * 2   = 2 * 2 √2 =   4 √2

Now that the radicals are the same. then you can subtract the numbers.

20 √2 - 4 √2 = 16√2
