Answer:
The second choice (-6, -5 2/5, -4 1/5)
Step-by-step explanation:
1) Find the nth term by using the rule given. Foil them out.
A(n) = -6 + 1/5n - 1/5
A(n) = 1/5n - 31/5
2) Find the first term by substituting 1 into n.
a1 = 1/5(1) - 31/5
a1 = -6
3) Find the fourth term by substituting 4 into n.
a4 = 1/5(4) - 31/5
a4 = -27/5 or -5 2/5
4) Find the tenth term by substituting 10 into n.
a10 = 1/5(10) - 31/5
a10 = -21/5 or -4 1/5
Therefore, the second choice (-6, -5 2/5, -4 1/5) is correct.

By what percent will the fraction increase if its numerator decreased by 30% and the denominator decreased by 50%
Answers
Answer:
140%
Step-by-step explanation:
So a fraction can be expressed as: [tex]\frac{a}{b}[/tex] and if a number decreases by x%, the new number is (100-x)% the original value. So since the numerator decreases by 30%, it's not 70% the original value, and it's very similar with the denominator, with it only retaining 50% of it's original value. This gives you the formula: [tex]\frac{0.70a}{0.50b}[/tex]. You can rewrite the fraction as: [tex]\frac{1.4 * 0.5 * a}{0.5 * b}[/tex] in doing so it's easy to see that you can cancel out the 0.5 and get: [tex]1.4\frac{a}{b}[/tex]. This means the value is increasing by 1.4 or 140%

What is a parallelogram?A quadrilateral in which opposite sides are parallel is called a parallelogram. Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
For a parallelogram, the pair of opposite sides are equal and parallel. Therefore,
1.) For the first pair.
(x+8) = 15
x = 7
2.) For the second pair
(x+2)=(2x-5)
x + 2 = 2x - 5
2 + 5 = 2x - x
x = 7
(x+2) = (7+2) = 9
Since the measure of the pair of opposite sides is 15 units, the pair of the other two sides measure 9 units.
Hence, the correct option is A.

This is a two-step problem.
Answers
The drug will decay to 82% of the initial dosage after 7.18 hours.
Finding the Decay constant(λ):
λ = 0.693 / (half-life)
we are given that the half-life is 47 hours
λ = 0.693 / (47)
λ = 0.01925 /hour
Time is taken for 82% decay:
How do find the decay?Since decay is first-order, we will use the formula:
[tex]t = \frac{2.303}{0.0192} log\frac{100}{82}[/tex]
Final amount = 100*82/100 = 82 mg
Replacing the values in the equation:

Given that A varies directly as B and inversely as C and that; A=12 when B=3 and C=2. Find B when A=10 and C=1.5
Answers
Answer:
B = 1.875
Step-by-step explanation:
given that A varies directly as B and inversely as C then the equation relating them is
A = [tex]\frac{kB}{C}[/tex] ← k is the constant of variation
to find k use the condition A = 12 when B = 3 and C = 2 , then
12 = [tex]\frac{3k}{2}[/tex] ( multiply both sides by 2 to clear the fraction )
24 = 3k ( divide both sides by 3 )
8 = k
A = [tex]\frac{8B}{C}[/tex] ← equation of variation
when A = 10 and C = 1.5 , then
10 = [tex]\frac{8B}{1.5}[/tex] ( multiply both sides by 1.5 )
15 = 8B ( divide both sides by 8 )
1.875 = B
