ABC-
8:6
XYZ-
14:11.20
ABC (unit rate)-
Divide both sides by 8...
1:0.75
XYZ (unit rate)-
Divide both sides by 14...
1:0.80
ABC is less, 0.80>0.75. The difference between the two is 0.05; 0.80-0.75=0.05.
So the answer is:
3. ABC is less expensive by $0.05 per pound.
It's linear. The x digits don't repeat.
Answer:
0.22
Step-by-step explanation:
So in this problem, we have to find the hypotenuse first, since sine is opposite over hypotenuse.
We can do this using the pythagorean theorem (you can search it if you don't know). Or, we can just remember this as one of our pythagorean triplets (9,40,41). The last side will be 41.
We have to find the value of sin(D)
opposite/hypotenuse = 9/41 = 0.2195 which is about 0.22
<u><em>Answer:</em></u>
C. System of non-linear equations
<u><em>Explanation:
</em></u>A system is defined as a group of equations/inequalities all having the same variables and are solved together.
Since we are looking for a system of <u>EQUATIONS</u>, we can exclude options A and D since they refer to inequalities
<u>Now, we are left with options B and C:</u>
<u>1- Option B:</u>
This options refers to a system of linear equations. This means that all equations in the system are linear. Therefore, this option is incorrect
<u>2- Option C:</u>
This option refers to a system of non-linear equations. This means that at least one of the equations in the systems is non-linear. This fits the description given in the question. Therefore, this is the correct option
Hope this helps :)
