Answer:
1.) 
≈ 3.652
2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.
Step-by-step explanation:
I think we may have the same class so hopefully this helps:
1.) 
--> law of cosines formula.
--> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.
--> in between steps.
--> more simplifying.
--> answer
2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.
Good luck! :)
Is it 2,280
Hope that work
Answer:
1250
Step-by-step explanation:
x^3*y^1
Let x = 5 and y = 10
5^3* 10^1
PEMDAS says powers first
125 * 10
Then multiply
1250
Answer:
10
Step-by-step explanation:
Mathematical Formula: 
Therefore: 
Which = 10
So if the delievery man weighs 160 pounds and the books is 40 pounds. and the capacity he can carry is 950 then we have to figure out how many books a 160 can carry.
Division: 160/40=4
950/4=237.5
i tried to answer it. unless i try one more strategy.
Multiply: 160*40=6400
Divison: 6400/950= <span>6.73684210526
</span>try and round that huge number and figure it out. because i tried. im sorry. i hope you passed.
