800(1+7)∧4
it will be $1048.63
Answer:
The correct answer is option C
a = 10√3, b = 5√3, c = 15 and d = 5
Step-by-step explanation:
Points to remember
The angles of a right angled triangle, 30°, 60° and 90° then sides are in the ratio, 1: √3 : 2
<u>To find the value of variables</u>
From the figure we can see 2 right angled triangle with angle 30, 60 and 90
we get, d= 5 then b = 5√3
b = 5√3 the c = 5√3 * √3 = 15
and a = 2 * 5√3 = 10√3
Therefore the correct answer is option C
a = 10√3, b = 5√3, c = 15 and d = 5
Answer:
B.
Step-by-step explanation:
The problem is saying 2/5 squared by -2 times -3 multiplied by itself 4 times.
2/5 multiplied by itself -2 times looks like this: -2/5 times -2/5.
-3 multiplied by itself 4 times looks like this: -3 times -3 times -3 times -3.
Put the two together and it looks like B.
Answer:
Step-by-step explanation:
Key to this method is remembering that
So, if you divide the coefficient of x by 2 and square it, that will complete the square. With that in mind, things are easy.
6/2 = 3, so add 
So, c=9
Similarly, for the other two,
You don't really have to worry about the sign, since squaring will always make it positive
For #3, it's 5.4 because you divide the total amount of money made by the amount of money earned per hour.
49.95/9.25=5.4 hours
