Answer:
176 hours
Step-by-step explanation:
They work 176 hours because
22*8=176
Answer:
Step-by-step explanation:
You have an angle bisector in AD. That means the sides are in proportion to to BD and DC
It's much easier just to look at the proportion.
AB / BD = AC/DC
18 / (3x - 3) = 15/(x + 5) Cross multiply
18*(x + 5) = 15 (3x - 3) Remove the brackets
18x + 90 = 45x - 45 Switch the sides.
45x - 45 = 18x + 90 Subtract 18x from both sides
<u>-18x -18x</u>
27x - 45 = 90 Add 45 to both sides
<u> +45 45</u>
27x = 135
x = 5
But that's not the answer (even though it is correct). You want BD
BD = 3x - 3
BD = 3*5 - 3
BD = 15 - 3
BD = 12
The first equation would be 650p+2200s =18150
The second equation would be p + s =16
The answer of is √ 2
<u>Step-by-step explanation:</u>
The value of = √2/ 2
The value of = √2/ 2
= √2/ 2 + √2/ 2
= √2 + √2 / 2
= 2 √2 / 2
Dividing √2 by 1
= √2
