Answer:
haha! You know the answer. Thanks tho!
Step-by-step explanation:
Answer:
c. Change the length of side CB to 8 feet
Step-by-step explanation:
If the figures are similar, the ratios should be the same
Take the side of the larger triangle over the same side of the smaller
PR PQ RQ
----------- = --------------------= ----------------
AC AB CB
7.5 5 10
----------- = --------------------= ----------------
6 4 9
7.5 /6 = 1.25
5/4 = 1.25
10/9 =1.1111(repeating)
The bases are not in the right ratio. RQ over CB = 1.25. Since RQ = 10 and the ratio is 1.25, we can solve for CB
10/CB = 1.25
Multiply by CB on each side
10 = 1.25CB
Divide by 1.25 on each side
10/1.25 = CB
8 =CB
Average= 9.625
average is when you add up all the numbers and divide by how many there are..
x,21,27,21,16,-2,-9,9
(x+21+27+21+16+-2+-9+9)/8=9.625
×8 both sides
x+21+27+21+16+-2+-9+9=77
x+83=77
-83 both sides
x= -6 degrees
It would be 6 km because 4 1/2 divided by 3 = 1.5x4=6
Time for entire trip = 2d/30 hours
Time for first part of trip = d/60.
Time for second part of trip, is given by:
Therefore the speed during the second distance d is 20 mi/h.
