Answer:
Step-by-step explanation:
If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.
If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes
y = k/x
When y = 0.25, x = 8
Substituting into the expression above, it becomes
0.25 = k/8
k = 0.25 × 8
k = 2
The inverse variation function is
y = 2/x
Perimeter is 2l+2w
100 =2(30) + 2w
100 =60 + 2w
-60 -60
40 = 2w
w=20 meters.
Answer:
answer = 12 min
Step-by-step explanation:
40% of 30 min = ?
10% of 30 min = 3
3*4 = 12
Thus, she spends 12 min of her 30 min lunch driving

Answer:
B
Step-by-step explanation:
Trapezoids have only one pair of parallel lines.
<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
