Answer:
300
Step-by-step explanation:
100% of 150 is literally 150, add those together and you get 300.
Answer:
The coordinates of P' are 
Step-by-step explanation:
Given a point (x,y). If we have a dilation by a scale factor of r, centered at the origin, we have that the coordinates of (x,y) in the new system is given by (r*x,r*y).
Assumign that this dilation is centered at the origin, then if P is the point (-6,4) then the point P' is 
Answer:
Part 5.1.1:

Part 5.1.2:

Step-by-step explanation:
We are given that:

Part 5.1.1
Recall that:

Let θ = 2<em>A</em>. Hence:

Square the original equation:

Hence:

Subtract:

Take the square root of both sides:

Since 0° ≤ 2<em>A</em> ≤ 90°, cos(2<em>A</em>) must be positive. Hence:

Part 5.1.2
Recall that:

We can use the third form. Substitute:

Solve for cosine:

In conclusion:

(Note that since 0° ≤ 2<em>A</em> ≤ 90°, 0° ≤ <em>A</em> ≤ 45°. Hence, cos(<em>A</em>) must be positive.)
Answer:
78 meters
Step-by-step explanation:
the big one is 9 x 10 =90 meters
The smaller one is 3 x 4 =12 meters
the remaining area is 90-12=78 meters
He went 90 miles, 180 minutes. explanation: there are 4 , 15 minute intervals in an hour. 4 x 15 is 30. so 30 miles an hour. you multiply 30 miles x 3 hours and get 90 miles. then there’s 60 minutes in an hour and 60 x 3 is 180.
