Answer:
111 Feet
Step-by-step explanation:
The feet of antique picket fencing are to be used to enclose the garden is equivalent to the perimeter of the flower garden.
The perimeter P of a rectangle whose length is L and width is W is given as
P = 2( L + W)
Given that the width is exactly two-thirds of the length
then, W = 2/3 L and P = 370 feet
L = 3/2 W = 1.5W
370 = 2 ( 1.5W + W)
370 = 5W
W = 370/5
= 74 Feet
L = 1.5W
= 1.5 * 74
= 111 Feet
Answer:
9/50
Step-by-step explanation:
Turning 18% to a decimal= .18. As you turn the decimal to a fraction, it gives you 9/50
9/50= .18
The measure of an arc is twice the measure of the inscribed angle that intercepts it.
m(arc)NL = 2 * 42 = 84
Answer:
D., x= 19.7 or ≈20. g
Step-by-step explanation:
P(x) = [100(15+x)]/(100+x)
When 0 g additional salt is added, x=0. we have
P(0) = [100(15+0)]/(100+0)= 15
x=0, P=15
We can see this point only on the graph D.
P(x) =29 = [100(15+x)]/(100+x)
29 = [100(15+x)]/(100+x)
29(100+x) = 100(15+x)
2900+29x = 1500+100x
2900-1500=100x-29x
1400 = 71x
x ≈ 19.7 g or ≈20. g
From the graph D, we can see that to get 29% we need to add ≈ 20 g of salt.
