The solution to the problem is as follows:
kilo -> 1000
<span>centi -> 100
</span>
<span>2.4 x 1000 g = 24 x 100 g. </span>
<span>So, on the left we have 2.4 kg, and on the right we have 24 cg
</span>
I hope my solutions has come to your help. Thank you and have a nice day ahead!
Answer:
Step-by-step explanation:
A.)
Let the equal number of hours be represented by variable h;
The two equations will be as follows;
Jack; 40 +30h
Mark; 50 +25h
Next, equate them;
40 + 30h= 50 + 25h
30h - 25h = 50 - 40
5h = 10
h =10/5
h = 2
Therefore, they charge the same amount at 2 hrs.
B.) The amount charged;
Replace the variable H in any of the two equations above with 2 to solve for the amount.
Equation 40+30h = 40 + (30*2)
=40 + 60
= $100
Answer: <ACB = 50 degrees
Step-by-step explanation: Since the interior angles of a triangle is always equal to 180 degrees, you would add both given degrees which is 40 and 90 (because of the right angle) and then subtract that answer (130) from 180
Given expression is sin(45)sin(15)
this expression best matches with left side of the formula:
2 sin(A) sin(B)= cos(A-B) - cos(A+B)
so we can plug given angles 45 and 15 there
2 sin(45) sin(15)= cos(45-15) - cos(45+15)
2 sin(45) sin(15)= cos(30) - cos(60)
sin(45) sin(15)= [cos(30) - cos(60)]/2
We are getting negative sign and cos in the solution while none of the given choices have same situation so answer will be none of them.
-----------
For cos(75)-cos(15), we will use formula:
Now plug the given angles
Hence choice B is correct.
