Answer:
1150%
Step-by-step explanation:
The percentage change is ...
percentage change = (amount of change)/(original amount) × 100%
= ((new amount) - (original amount))/(original amount) × 100%
= ($1250 -$100)/$100 × 100%
= 1150/100 × 100%
= 1150%
Answer:
The answer is B. 9
Use cosine rule. In this case, I am using SOH and the right triangle:
sin 60°= a ÷ 6 root 3
(6 root 3)(sin 60°)= a
a=9

Answer:
x = 67.5
Step-by-step explanation:
Because AB and NP lines are parrallel, we can find out the scale factor by dividing size MA by MN.
This works because you find out what the MA size has to be multiplied to to get to MN, which will also work in reverse to find angle MB from MP.
71.5 - 22 = MA = 49.5
71.5 ÷ 49.5 = 
So to get to line MP length, line MB had to be multiplied by
to get 97.5
The reverse of this is dividing 97.5 by
:
97.5 ÷
= 67.5
So x = 67.5

Step-by-step explanation:
The text of this expression is:
"If 3 is added to twice a number, the result is 17. Find the number"
Let's call
the number we want to find.
Twice the number is equal to

So, if we add 3 to 2x, we get

And we know that this is equal to 17:

Now we can solve the equation to find x: first, we subtract 3 from both sides

Now we divide both sides by 2:
