Answer:
The volume of water the pond will lose in 31 hours is 17.71 gallons.
Step-by-step explanation:
Given;
Rate of water leakage, R = 12 gallon of water in 23 hours
[tex]R = \frac{12 \ gallons}{23 \ hours}[/tex]
In 31 hours the volume of water leaked is calculated as;
[tex]V = \frac{12 \ gallons}{21 \ hours} \times 31 \ hours\\\\V = 17.71 \ gallons[/tex]
Therefore, the volume of water the pond will lose in 31 hours is 17.71 gallons.

Is the equation y=4x+1 proportional? *
Yes
No
Answer:
No
Step-by-step explanation:
y = 4x + 1 is not a direct variation. Direct variations have the form y = kx. So y = 4x would be a direct variation (k=4), but not y = 4x+1

Express each ratio as a fraction in its simplest form 6 minutes to 1 hour
Answer:
1:10
Step-by-step explanation:
1 hour is 60 minutes, so the ratio is 6:60.
To simplify, divide both sides by 6.
Thus, you get:
1:10.

Answer:
y+3=-1/2(x-1)
Step-by-step explanation:
Point-slope form of a line is given by the equation y - b = m(x - a), where,
(a, b) = is a point on the line
m = slope of the line.
A line that is perpendicular to y = 2x - 1 will have a slope value that is the negative reciprocal of the slope of the line.
The slope of the line, y = 2x - 1, is 2.
The negative reciprocal of 2 = -½.
The slope of the line that is perpendicular to y = 2x - 1 is -½.
Thus, m = -½.
Let's find the equation of the perpendicular if it passes through the point (1, -3).
Substitute (a, b) = (1, -3), and m = -1/2 into y - b = m(x - a).
Thus:
y - (-3) = -1/2(x - 1)
y+3=-1/2(x-1)

Melanie is looking for a loan. She is willing to pay no more than an effective rate of 9.955% annually. Which, if any, of the following loans meet Melanie’s criteria?
Loan A: 9.265% nominal rate, compounded weekly
Loan B: 9.442% nominal rate, compounded monthly
Loan C: 9.719% nominal rate, compounded quarterly
a.
B only
b.
A and C
c.
A and B
d.
None of these fit Melanie’s criteria.
Answer:
The correct answer is C.
Step-by-step explanation:
Giving the following information:
Loan A: 9.265% nominal rate, compounded weekly
Loan B: 9.442% nominal rate, compounded monthly
Loan C: 9.719% nominal rate, compounded quarterly
To calculate the effective annual rate, we need to use the following formula:
Effective annual rate= [(1+i)^n] - 1
Loan A:
i= 0.09265/52= 0.001782
Effective annual rate= [(1.001782^52) - 1]
Effective annual rate= 0.097 = 9.7%
Loan B:
i= 0.09442/12= 0.007868
Effective annual rate= [(1.007868^12) - 1]
Effective annual rate= 0.0986 = 9.86%
Loan C:
i= 0.09719/4= 0.02439
Effective annual rate= [(1.02439^4) - 1]
Effective annual rate= 10.11%
Answer:
c

12. x + y = -3
13. -2x + 3y = -6
Answer:
in order
y = -3x + 5
y = 1/2(x) + 2
y = -x - 3
y = 2/3(x) - 2
Step-by-step explanation:
slope-intercept form is y= mx + b
10. 6x + 2y = 10
2y = -6x + 10, subtract 6x from both sides
y= -3x + 5, divide both sides by 2
11. x + 2y = 4
2y = x + 4, subtract x from both sides
y = 1/2(x) + 2, divide both sides by 2
12. x + y = -3
y = -x - 3, subtract x from both sides
13. -2x + 3y = -6
3y = 2x - 6, add 2x to each side
y = 2/3(x) - 2, divide both sides by 3

Answer:
a) [tex]x=\frac{y}{m}-\frac{b}{m}[/tex]
b) [tex]m=\frac{y}{x}-\frac{b}{x}[/tex]
Step-by-step explanation:
We are given the equation:
y = mx + b
Part A:[tex]y=mx+b\\\\mx+b=y\\\\mx+b-b=y-b\\\\mx=y-b\\\\\frac{mx=y-b}{m}\\\\\boxed {x=\frac{y}{m}-\frac{b}{m}}[/tex]
Part B:[tex]y=mx+b\\\\mx+b=y\\\\mx+b-b=y-b\\\\mx=y-b\\\\\frac{mx=y-b}{x}\\\\\boxed{m=\frac{y}{x}-\frac{b}{x}}[/tex]Hope this helps!
