Find the volume of the following figure. Round the answer to the nearest hundredth if necessary.

telo118 [61]

Answer:

48 yd^3.

Step-by-step explanation:

Volume of a pyramid = 1/3 * height * area of the base.

The area of the triangular base = 1/2 * height * base = 1/2*6*8

= 24 yd^2.

So the volume of the figure

= 1/3 * 6 * 24

= 2*24

= 48 yd^3.

A mixture of compounds X and Y in a 0.100-cm cell had an absorbance of 0.215 at 272 nm and 0.191 at 327 nm. Find [X] and [Y] in

Oksi-84 [34.3K]

Answer: The concentration of X is $7.13582\times 10^{-6}$ and the concentration of Y is $2.53159\times 10^{-5}$ .

Step-by-step explanation:

Since we have given that

At 272 nm, absorbance = 0.215

At 327 nm, absorbance = 0.191

As we have given that

Compound X Compound Y

272 16400 3870

327 3990 6420

So, our equations becomes

$16400C_1+3870c_2=0.215\\\\3990C_1+6420C_2=0.191$

By solving these two equations, we get that

$C_1=7.13582\times 10^{-6}\\\\C_2=2.53159\times 10^{-5}$

Hence, the concentration of X is $7.13582\times 10^{-6}$ and the concentration of Y is $2.53159\times 10^{-5}$ .

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. What is the volume of t

katen-ka-za [31]

Answer/Step-by-step explanation:

Volume = L*W*H

L = 10.4

W = 5

H = 8

10.4* 5 = 52

L*W = 52

52* 8 = 416

L*W*H = 416

Therefore,

ANSWER: 416

if needed in volume form 416^3
