Hello there!
First, we need to admit that math is a hard subject. So, how do we handle hard stuff? We find an easy way. Right?
Well same goes here. They give the fractions to drive us crazy. Let's find the easiest way...
The easiest way is to turn them into decimals.
1 3/7 = 1.42 which is the amount of pages he reads
2/3 = 0.67 minute.
The are asking us how many pages does he reads per minute.
So we gonna say:
Charlie reads 1.42 pages ......> 0.67
Charlie reads x pages.............> 1minute
Cross multiply
0.67 * x = 1 * 1.42
0.67x = 1.42
x = 1.42/0.67
x = 2.11
So, Charlie reads 2.11 pages in 1 minute.
I hope this helps. Please let me know if you have questions about the answer.
Thanks!
Answer:
remaining portion is area= area of rectangle- area of semicircle
= 18*14 - 3.14*7^2
=252-154.86
=199.86cm^2
According to the valence number of copper(2+) and the same value for chlorine (1-) copper (II) chloride has the formula of CuCl2
The molar mass of copper is 0,0635 kg/mole and chlorine gas a molar mass of 0,035 kg/mole the compound will have a molar mass of ( 0,0635+2×0,035 )kg/mole=0,099kg/mole and 0,344 moles are equivalent in mass to 0,344×0,135 kg=0,046 kg
Answer:
![\cos(C)=\frac{120}{169}](https://tex.z-dn.net/?f=%5Ccos%28C%29%3D%5Cfrac%7B120%7D%7B169%7D)
Step-by-step explanation:
The triangle is shown in the attachment.
Recall that;
![\cos(C)=\frac{Adjacent}{Hypotenuse}](https://tex.z-dn.net/?f=%5Ccos%28C%29%3D%5Cfrac%7BAdjacent%7D%7BHypotenuse%7D)
This implies that;
![\cos(C)=\frac{|AC|}{|BC|}](https://tex.z-dn.net/?f=%5Ccos%28C%29%3D%5Cfrac%7B%7CAC%7C%7D%7B%7CBC%7C%7D)
We substitute the values into the ratio to obtain
![\cos(C)=\frac{120}{169}](https://tex.z-dn.net/?f=%5Ccos%28C%29%3D%5Cfrac%7B120%7D%7B169%7D)
