20 jasmine flowers? just do tally marks and count how many times you did them because each tally has five so you subtract the four from the five and count the tallys you have left
To find 2/3 of an hour first we will divide 1 hour that is 60 mins into 3parts so we will get 20 mins.
Well I don't know !
Let's check out the choices:
A). 3a - 4b = 21, a=0, b=7
3(0) - 4(7) = 21
0 - 28 = 21 Nope. That's not true.
B). 3a - 4b = 21, a=-3, b=2
3(-3) - 4(-2) = 21
-9 + 8 = 21
-1 = 21 Nope. That's not right.
C). 3a - 4b = 21, a=-2, b=-3
3(-2) - 4(-3) = 21
-6 + 12 = 21
6 = 21 Nope. That's not it.
Only one choice left.
This one had better be it:
D). 3a - 4b = 21, a=7, b=0
3(7) - 4(0) = 21
21 - 0 = 21
21 = 21 Yay ! That's it !
Answer:
11.3
Step-by-step explanation:
Pythagorean theorem is a^2+b^2=c^2
8^2+8^2=128
the square root of 128 is 11.3137085
then you round to the nearest tenth and get 11.3
Q' = (7, 2 ) and R' = (1, - 5 )
given P(- 4, 4 ) and P'(3, 1 ), then the translation vector is
v = < 3, 1 > - < - 4, 4 > = < 7, - 3 >
Thus to obtain the coordinates of the images, add 7 to the x-coordinate and subtract 3 from the y-coordinate
Q(0, 5 ) → Q'(0 + 7, 5 - 3 ) → Q'(7, 2 )
R(- 6, - 2 ) → R'(- 6 + 7, - 2 - 3 ) → R'(1, - 5 )
