Answer:
19.80
Step-by-step explanation:
use the is/of x %/100 method.
33/100 x x/60
1980/100x = 19.80$
<u>coordinates of the point are (2,6) and (3,4)</u>
Answer:
Solution given:
let the given point be A(1,8) and B(4,2).
P and Q are the two points on AB such that
AP=PQ=QB=k
now
comparing AP and PB
AP=k
PB=2k
ratio of AP and PB =
= ratio 1:2
now
finding p
for this

For AB


now by using division formula


similarly
Q divides AB
Ratio of AQ and QB =
= ratio 2:1



by using division formula


A graphing calculator is a great help for problems of this nature.
x ∈ {-5.63, -0.55, 2.59}
Question - Answer
a) 1/2 L = 4
b) 1/2 L x 4 = 2
c) 5/6 x 2 = 1 4/6 L OR 1.67 L
d) 2/3 L = 3 beakers with 2/3 OR 5 beakers with 2/3 and 5/6
e) <1/3 L = 3 beakers
I believe that is the answer.
I would need to have the same book and go to page 73 to be able to answer it. By the way, do you have any friends that have the answer?
