Answer:

50x + 9500 ≤ 27500

x ≤ 360

Step-by-step explanation:

50x + 9500 ≤ 27500  Subtract 9500 from both sides

50x + 9500 - 9500 ≤ 27500 - 9500

50x ≤ 18000  Divide both sides by 50

\(\frac{50x}{50}\) ≤ \(\frac{18000}{50}\)

x ≤ 360

By using basic meaning of percentage we got that the originally puppy's weight  was 50 pounds

Percentage is a number or ratio expressed as a fraction of 100.

Here given that Juan's puppy currently weighs 80 pounds and his is a 60% increase in weight from when he got her.

Let's suppose original weight of puppy was x pounds

We can calculate x as

\(x+ \frac{60}{100} \times x=80\\\\x+ \frac{6}{10} \times x=80\\\\x+ 0.6\times x=80\\\\\\1.6x=80\\\\x=\frac{80}{1.6} \\\\x=\frac{800}{16} \\\\\\x=50\)

By using basic meaning of percentage we got that the originally puppy's weight  was 50 pounds .

2. 1.8 m/s^2

Step-by-step explanation:

See the attached worksheet.

A time versus speed graph contains a small treasure of mathematical rewards. The area under the graph is equal to the distance travelled. The slope of the line segments represents acceleration.

For total distance: If we break the graph into three sections (2 triangles and a rectangle) we can calculate the areas for each. Each area is the distance travelled for that segment. As shown on the workseet, the total area is 2430 miles, the distance travelled by the train for this question.

The slope of the line in the first 10 seconds is 1.8 meters/sec^2, the acceleration of the train over that period.

The axis of symmetry divides a shape into congruent halves, such as a parabolic curve or a quadratic function's graph. It is determined by the vertex or calculated using the formula -b/2a. The rank of the three functions are h(x), g(x), and f(x).

The axis of symmetry is a line that divides a two-dimensional shape or a three-dimensional object into two congruent halves.

The axis of symmetry is a line that divides a parabolic curve into two equal sections.

If the quadratic function's equation is given in vertex form, f(x) = a(x - h)2 + k, where the vertex is (h, k) and "a" is a coefficient, the axis of symmetry is the line x = h.

The graph of a quadratic function is symmetric about the axis of symmetry. A graph of a parabola is symmetrical about its axis of symmetry, which passes through its vertex.

For the quadratic function g(x) = 2x2 - 8x + 6, the axis of symmetry can be found using the formula x = -b/2a; the axis of symmetry is x = 2.

The axis of symmetry of f(x) = -3(x - 4)2 - 1 is x = 4, and the axis of symmetry of h(x) = x2 + 2x + 3 is x = -1 (Note: vertex form and standard form).

To sum up, based on the order of the axis of symmetry, the rank of the three functions is as follows: h(x), g(x), and f(x).

Answer: can you please give me answer choices

Step-by-step explanation:

As proportional relationship, the amount decreasing at a rate milligrams per hour can be written in expression P(t) = 500 + e⁻⁰²ˣ

In math, the relationships between two variables where their ratios are equivalent is known as proportional relationship.

Given that P(t) represent the amount of a certain drug, in milligrams, that is in the bloodstream at time t hours.

Here we have the rate at which the drug leaves the bloodstream proportional to the amount of the drug bloodstream.

The amount of the drug in the bloodstream can be modeled by dP/dt = kP, where k is a constant and t is time, in hours.

Here we need to find the expression.

Bloodstream = 500 milligrams

So, the expression for this proportional relationship is written as;

Interest = A - (50 * 456)

To determine how much you will have in the IRA when you retire at age 65, we can use the formula A = P[(1 + r)^t - 1] / r, where A is the future value, P is the monthly deposit, r is the monthly interest rate, and t is the number of months.

a. In this case, the monthly deposit is 50, the monthly interest rate is 5% or 0.05, and the number of months is (65 - 27) * 12 = 456 (from age 27 to 65).

Using the formula, we can calculate:
A = 50[(1 + 0.05)^456 - 1] / 0.05

b. To find the interest, we can subtract the total deposits from the future value:
Interest = A - (P * t)

In this case:
Interest = A - (50 * 456)

The salt that is left after t minutes is y = 16e^[-t/100]

We have to mix problems we use:

dy / dt = (rate in) - (rate out)

The water entering the tank at a speed of 10 L / min but it has no salt, therefore

rate in = 0

The tank has 1000 liters of brine with 16 kg of salt initially, therefore the concentration of salt at time "t" is:

y (t) / 1000

then rate out would be:

rate out = y (t) / 1000 * 10 = y (t) / 100

The difference equation would then be:

dy / dt = 0 - y (t) / 100

1 / y (t) * dy = 1/100 * dt

We integrate from both sides and we have:

ln y = - (1/100) * t + C1

y = e ^ [- (1/100) * t + C1]

y = e ^ [- (1/100) * t] * e ^ [C1]

We assume that C = e ^ [C1]

Thus:

y = C * e ^ [- (1/100) * t]

now y = 16 to t = 0, replacing:

16 = C * e ^ [- (1/100) * 0]

16 = C, therefore we would have:

y = 16*e ^ [- t / 100]

The percentage loss if I buy a Mobile phone for £450 and sell it for £292.50 is 35%.

The mobile phone was bought for £450 therefore,

Buying price = 450

He sold it later for  £292.50 so,

Selling price = 292.5

Therefore, the loss he incured is 450 - 292.5 = 157.5

So the percentage loss by selling the phone for 292.50 is,

= Total loss/ Initial amount

= 157.5 / 450

= 0.35

= 35%

Therefore, The percentage loss if I buy a Mobile phone for £450 and sell it for £292.50 is 35%.

Answer:

Paint Needed = 1.25 gallons = It means 1 gallon and 1 quart of paint is needed to paint the Briellie's room.

Step-by-step explanation:

As, this question is incomplete, so we will create similar question and complete it. '

Let's suppose Brielle's room has following dimensions:

Length of two walls =  10 ft

Length of other two walls = 12 ft

Height of the room from bottom to ceiling = 10 ft

In order to calculate the amount of paint needed, we need to calculate the surface area of the room to be painted.

So, for that, add all the lengths together and multiply it by height of the room.

SF = (L1 +L2 +L3+ L4) x H

SF = (10 + 10 + 12 + 12) x (10)

SF = 440 sq.ft = Actual footage of the room to be painted.

Now, we have convert this number in gallons to know the amount of paint required to paint Brielle's room. For this, we need to divide our SF to 350 sq.ft per gallon.

Paint Needed = 440 sq.ft / 350 sq.ft per gallon

Paint Needed = 1.25 gallons = It means 1 gallon and 1 quart of paint is needed to paint the Briellie's room.

1. It must be possible to accurately measure the temporal changes in star brightness.

2. Seen from Earth, the orbits of the planets should lie roughly sideways (in the plane of our line of sight).

3. We need to obtain the repeat spectrum of the star that the planet orbits.

The transit method is a very important and effective tool for discovering new exoplanets (planets orbiting other stars outside our solar system). With this method, stars are observed over a longer period of time. When an exoplanet crosses in front of these stars as seen from Earth, the brightness of the stars diminishes. To observe this slope, the following conditions must be met:

1. The planet's orbit must be coplanar with the line-of-sight plane. Then you can observe just that transition.

2. When viewed from Earth, the transit time can be less than a second of her, so the brightness of the star must be carefully monitored.

3. The decrease in brightness also depends on the size of the planet. If the planet is not very large, the intensity drop is very small.

The solution of the linear equation in one variable 4y - 6 = 2y + 8 is at y = 7.

According to the given question.

We have a linear equation in one variable.

4y - 6 = 2y + 8

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, the solution of the linear equation in one variable 4y - 6 = 2y + 8 is given by

4y - 6 = 2y + 8

⇒ 4y - 2y - 6 = 8     ( subtracting 2y from both the sides)

⇒ 2y -6 -8 = 0           (subtracting 8 from both the sides)

⇒ 2y - 14 = 0

⇒ 2y = 14

⇒ y = 14/2

⇒ y = 7
