BCD Are All Correct
Hope This Helps
Answer:
Addition and subtraction are inverse operations. Start with 7, then add 3 we get 10, now subtract 3 and we get back to 7.
Another Example: Multiplication and division are inverse operations. Start with 6, multiply by 2 we get 12, now divide by 2 and we get back to 6.
The formula for a circle is:
(x-p)^2+(y-q)^2=r^2
The radius is given (r=6), as well as the centre of the circle (-2;3).
"p" and "q" represent the coordinates of the centre of the circle.
So it would look like this -
(x-p)^2+(y-q)^2=r^2
p=x-coordinate (-2)
q=y-coordinate (3)
r=6
(x-(-2))^2+(y-(3))^2 =6^2
(x+2)^2 + (y-3)^2 = 36
***"^" means "to the power of"

Answer:
.5 hour, or 30 minutes
Step-by-step explanation:
280 km / 80 kmh = 3.5 hr before limiter
280 km / (80-10) kmh = 4 hr after
so .5 hour from 3.5 to 4 hours. or 30 minutes
This is provided he matains this speed at all times.
Answer: Rick can type 1350 more words than Raquel.
We will follow through these 3 steps to find the answer
1) Find the number of words Raquel can type in 135 mins.
2) Find the number of words Rick can type in 135 minus.
3) Numbers of words Rick can type - Numbers of word Raquel can type.
------------------------------------------------------------------------------------------
Find the number of words Raquel can type in 135 mins
------------------------------------------------------------------------------------------
1 minute = 63 words
x135 x135
135 minutes = 8505 words
------------------------------------------------------------------------------------------
Find the number of words Rick can type in 135 mins
------------------------------------------------------------------------------------------
1 minute = 73 words
x 135 x135
145 minutes = 9855 words
------------------------------------------------------------------------------------------
Find the difference
------------------------------------------------------------------------------------------
9855 - 8505 = 1350
------------------------------------------------------------------------------------------
Answer: Rick can type 1350 more words than Raquel.
