Answer:

19. 1 do 4^5 which is 1024 then do 1024^0 which is 1

21. 0.000064 do 5^-2 which is 0.04 then do 0.04^3 which is 0.000064

23. 2.33 do 9^4 which is 6561 then do 6561^-2 which is 2.32305731 so you round it to 2.33

btw you should talk to me more

Find x and y, given that line WS and line VT are parallel. Show all work!

bulgar [2K]

In the given diagram, the traingles USW and UTV are similar triangles and thus the following ratio equality applies to them.

$\frac{VT}{WS} =\frac{VU}{WU}=\frac{TU}{SU}$ ..........(Equation 1)

Checking the diagram given, we see that:

VT=y, WS=22, VU=8, ST=x-2

WU=WV+VU=12+8=20

TU=5

SU=ST+TU=(x-2)+5=x+3

Thus, substituting the required values in (Equation 1) we get:

$\frac{y}{22}=\frac{8}{20}=\frac{5}{x+3}$

Now, as can be clearly seen, to find y we will use the first two ratios as:

$\frac{y}{22}=\frac{8}{20}$

$y=\frac{8\times 22}{20}=8.8$

In a similar manner, to find the value of x we can use the last two ratios:

$\frac{8}{20}=\frac{5}{x+3}$

After cross multiplication we get:

$5\times 20=8(x+3)$

Which can be simplified as:

$x+3=\frac{100}{8} =12.5$

Thus, $x=12.5-3=9.5$

Therefore, the required answer is:

x=9.5 and y=8.8

Lee works for a company that ships packages and must measure the size of each box that needs to be shipped. Lee measures a box a

expeople1 [14]

Answer: 1852.5 cubic inches

Step-by-step explanation:

The Volume of cuboidal box is given by:-

$Volume=length\times width\times\ height$

Given: The length of box = $9\frac{1}{2}\ inches=\frac{19}{2}\ inches$

The width of the box = $15\ inches$

The height of the box = $13\ inches$

Now, the volume of box is given by:-

$Volume=\frac{19}{2}\times15\times13=\frac{3705}{2}=1852.5\ inches^3$

What is the answer to this problem?

leonid [27]

Answer:

Surface area = 24in

Step-by-step explanation:

I think its 6in x 4in

so like since the green cylinder is 6in i think you multiply it with the purple (sorry if I’m wrong)

Find the volume of a cylinder with a radius of 4 in and a height that is 3 times the radius

german

Answer:

Volume of a cylinder: V = π * r² * h ,

Base surface area of a cylinder: A_b = 2 * π * r² ,

Lateral surface area of a cylinder: A_l = 2 * π * r * h ,

Total surface area of a cylinder: A = A_b + A_l ,

Step-by-step explanation:

So, when the radius is tripled, the volume will be 3 squared = 9 times than the previous one.
