Aiko works in the fish department of a pet store. She must drain, clean, and refill two reef tanks. the first tank hold 175 gallons of water and drains at a rate of 25 gallons per hour. The second tank holds 200 gallons of water and drains at a rate of 30 gallons per hour.

1. Write an equation for each tank representing the total amount of water in gallons in the tank, y, in terms of the number of hours, x, that the tank drains

2. what is the solution to this system of equations.

3. suppose Aiko starts draining the tanks at the same time. When will both tanks have the same amount of water? How much water is in each tank at that time

Answer: x = 26

Step-by-step explanation: All you need to do is to add up given two unknown angles. Then, you can solve the equation for 180 degree. Because in this case, these angles are complementary to 180 degrees.

If you add them up:

[tex]8x - 28 = 180\\x = 26[/tex]

So, the answer is 26.

If a circular mulch bed has a radius of 1.6 feet. A bag of mulch contains 2 cubic feet of mulch. The mulch's depth to an appropriate number of significant digits is: C. 0.25 foot.

The volume of the mulch bed is given by the formula for the volume of a cylinder:

V = π * r^2 * h

Where:

r = radius (1.6 feet)

h=  the height (the depth of the mulch).

Since we have 2 cubic feet of mulch, and want to spread it evenly over the bed, we can set 2 = π * r^2 * h and solve for h:

h = 2 / (π * r^2) = 2 / (π * 1.6^2)

h ≈ 0.25 feet

Therefore the depth of the mulch is approximately 0.25 feet.

For given equation of circle radius is 6 unit and center is at (-2,1).

What is a circle?

A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the center. The distance from the center of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.

The equation of circle in the plane is given as:

(x-h)^2 + (y-k)^2 = r^2

where (x, y) are the coordinate points

(h, k) is the coordinate of the center of a circle

and r is the radius of a circle.

Now,

As shown in graph the graph by taking two points on graph

Step-by-step explanation:

The polynomial, so d can be any value less than b.

A polynomial is an expression made up of multiple terms, each of which is a number, a variable, or the product of a number and one or more variables. Polynomials are typically used to model real-world scenarios including, but not limited to, population growth, force and acceleration, and angles of elevation. Each term of the polynomial is separated from the others by an addition or subtraction sign.

Given the polynomial 4x^3 + ax^2 + bx + c,
a = 4, b = -3, c = 5, d = -2.
To find the values of a, b, c, and d, we need to compare the coefficients of the polynomial to the given values.
The coefficient of the term with the highest degree (x^3) is 4, so a = 4.
The coefficient of the next degree (x^2) is a, so a = -3.
The coefficient of the next degree (x) is b, so b = 5. The coefficient of the constant term is c, so c = -2. Finally, d is not given in the polynomial, so d can be any value less than b.

If you purchase the car with this loan, you will have to pay a total of $5,400 in interest.

To calculate the interest rate used for this loan, we can use the formula:

Interest rate = (Monthly payment x 12) / Principal

Plugging in the given values, we get:

Interest rate = ($450 x 12) / $10,000 = 0.54 or 54%

To calculate the total interest paid on the loan, we can use the formula:

Total interest = Principal x Interest rate

Plugging in the given values, we get:

Total interest = $10,000 x 0.54 = $5,400

The cannonball will be at a height of 640 feet for the first time after 6.5 seconds.

Acceleration, is a rate at which velocity changes with time, in terms of both speed and direction.

The time it will take for the cannonball to reach a height of 640 feet for the first time can be found using the equation:

t = (vf - vi) / a

where:

t = time (in seconds)

vf = final velocity (in feet per second) = 0 (at the top)

vi = initial velocity (in feet per second) = 208

a = acceleration (in feet per second squared) = -32 (upwards)

Plugging in the values:

t = (0 - 208) / (-32) = 6.5 seconds.

So, the cannonball will be at a height of 640 feet for the first time after 6.5 seconds.

By using the fact that the triangles are similar, we can write and solve an equation to find that t = 11.

Here we know that K is the midpoint of GJ and I is the midpoint of HJ, this means that triangle JKI is similar to JHG, but dilated by a factor 1/2.

That means that we can write:

(1/2)HG = IK

We know that:

GH = t + 47

IK = -5t + 84

Replacing these in the equation above, we will get:

(1/2)*(t + 47) = -5t + 84

t + 47 = 2*(-5t + 84)

t + 47 = -10*t + 168

t + 10t = 168 - 47

the equation that can be used to determine the value of the artwork in "x" year is A = 1500(1 + 0.0128)^x.

An equation that can be used to determine the value of the artwork in "x" years is a compound interest equation. This type of equation is used to calculate the value of an investment over time, taking into account the initial investment amount and the interest rate.

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It can be contrasted with simple interest, which is calculated only on the principal amount.

Compound interest is considered to be more beneficial for savers and investors, as it allows for interest to be earned on previously earned interest, leading to faster growth of the principal.

In this case, the artwork appreciates by 1.28% in value every year and was purchased for $1500. The formula for compound interest is:

A = P(1 + r)^n

Where:

A = the future value of the artwork

P = the initial investment (the purchase price of $1500)

r = the interest rate (1.28% per year)

n = the number of years

To use this equation, we need to convert the interest rate from a percentage to a decimal. We do this by dividing the interest rate by 100. So, 1.28% as a decimal is 0.0128.

Now we can substitute the values into the equation:

A = 1500(1 + 0.0128)^x

Therefore, the equation that can be used to determine the value of the artwork in "x" year is A = 1500(1 + 0.0128)^x.

Answer:

3. (-4/5, -3) 6. (4, 12/-5)

Step-by-step explanation:

3. so first we have

-5x - 10y = 20

-5x - 8y = 14

so first we have to have the x's be opposite so we multiply the top one by -1 which gets us

5x + 10y = -20

-5x - 8y = 14

then we cancel out the x's and subtract 10 by 8 and -20 by 14 so it's now

2y = -6

then we divide by 2 on both sides so it's

y = -3

but now we have to solve for x so we substitute y in on the bottom equation so now it is

-5x - 8(-3) = 20

now we multiply

-5x + 24 = 20

subtract 24 from both sides

-5x = -4

divide by -5

x = -4/5

then put it in coordinates

(-4/5, -3)

6. so we have

x = 4

-4x - 5y = 4

so first we have to substitute the top in for the bottom so now we have

-4(4) - 5y = 4

distribute

-8 - 5y = 4

add 8 to both sides

-5y = 12

divide

y = 12/-5

Graph y=-7 by plotting y-intercept (0,-7) and all points have y=-7, it is a horizontal line.

What is graph ?

A graph is a mathematical structure used to represent relationships between objects. In a graph, objects are represented by vertices (or nodes) and relationships are represented by edges (or arcs). Graphs can be used to model a wide variety of real-world systems, including networks of roads, social networks, and the internet.

To graph y = -7, you can start by plotting the y-intercept, which is the point at which the line crosses the y-axis. In this case, the y-intercept is (0, -7) because when x = 0, y = -7.

To graph the line, you can then pick any other x-value, substitute it into the equation, and find the corresponding y-value. For example, if you pick x = 1, then y = -7. So, you can plot the point (1,-7) on the graph.

You can repeat this process with different x-values and plot more points on the graph.
