Plumber A charges $50 to come to your house, plus $40 per hour of labor. Plumber B charges $75 to come to your house, plus $35 per hour of
labor. If y is the total dollar amount charged for x hours of labor, which of the following systems of equations correctly represents this
situation?

Answer:

[tex]\huge\boxed{\sf Option \ 1}[/tex]

Step-by-step explanation:

People surveyed = 42

People who approved = 25

So, the sample is:

25 residents who approve.

And population:

42 residents surveyed.

Step-by-step explanation:

hat is the measure of XYZ?

Let's call C the point on K(O) and segment AO.  I assume you're aware of a 'secant tangent angle theorem', where if you know the measure of arc BC you can solve for angle BAD.  Since CD is a diameter of the circle, the measure of arc CD is 180 degrees - with this you can easily find the measure of all arcs of the circle then apply the theorem

Answer:

5 ft

Step-by-step explanation:

If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.

[tex]1\frac{2}{3}[/tex] × 3

[tex]1\frac{2}{3}[/tex] can be rewritten as [tex]\frac{5}{3}[/tex], so:

[tex]\frac{5}{3}[/tex] × [tex]\frac{3}{1}[/tex]

[tex]= \frac{15}{3}[/tex]

The numerator & denominator share a common factor of 3, so:

5 ft is the final answer/perimeter.

hope this helps!

Answer:56 bags

Step-by-step explanation:

you are dividing 40 into 5/7 so its technically 40*7 divided by 5, which equals 56. double check by doing 56*5 divided by 7 and you get 40 pounds,

[tex]\frac{40(7)}{5}[/tex]Answer:

To find out how many can be filled, divide the number of pounds of candy by the number of pounds a single bag can hold.

40 can be considered 40/1.

So,

40/1 ÷ 5/7

Make 5/7 a reciprocal(basically flipping the fraction upside down):

40/1 ÷ 7/5

Convert the division symbol into a multiplication symbol:

40/1 × 7/5

Solve!

[tex]\frac{40(7)}{5}[/tex]

Cancel:

[tex]\frac{8(7)}{1}[/tex]

= 56 bags can be filled.

Answer:

Answer: A=10240033.0/pift /ft

The radius of the sphere is 4.2 feet.

A sphere is a geometrical shape in three dimension which has every point on the surface of it at an equal distance from a common point called the center of the sphere.

Volume of a sphere is given by the equation,

Volume = [tex]\frac{4}{3}[/tex]πr³, where r is the radius.

We have volume of the given sphere = 320 feet³

Substituting this value in the main equation, we get,

320 =  [tex]\frac{4}{3}[/tex]πr³

320 × 3 = 4πr³

960 / 4π = r³

960 / (4 × 3.14) = r³

r³ = 76.43

r = 4.24 ≈ 4.2

Hence, the radius of the sphere with a volume of 320 feet³ has a radius of 4.2 feet, to the nearest tenth of a foot.

Answer:

Step-by-step explanation:

Beth's position over time is constant, which makes the problem a lot easier. You are asked for the rate of position versus time, so begin by doing that. Since the rate is constant, clearly from the table, you can take any two data points and take their ratio. Her rate would be 11 feet every 5 seconds, or equivalently 2.2 feet every second. To graph the data, put position on the y-axis and time on the x-axis. The slope will be 2.2 at every point along her bike ride.

Moving on to the third part. If Amy traveled at a rate of 75 feet every 30 seconds, then she would be traveling 2.5 feet every second. Amy's rate is larger than Beth's rate. Since the rate corresponds to the slope of the postion vs. time graph, Amy's graph will have a steeper incline since the slope is 2.5

Answer:

B. Every 5 minutes 11 ft. traveled

2.2ft.= every 1 minute

C. Steeper. this is because her rate of change is much higher than before

Answer: 1 3/10

Step-by-step explanation:

first turn it into a fraction 13/10 then how many times does 13 fit into 10. It fits once with 3 remaining. So you get 1 and 3/10

Answer:

  1 3/10

Step-by-step explanation:

When you read the decimal number, it reads the same as the equivalent mixed number:

  1.3 = "one and three tenths" = 1 3/10

__

Additional comment

This will generally be the case. Some mixed numbers found this way can have their fractions reduced:

  1.2 = "one and two tenths" = 1 2/10 = 1 1/5

Answer:

[tex]\dfrac{dy}{dx}=-y\left(4+\dfrac{1}{x}\right)[/tex]

or written in rational form:

[tex]\dfrac{dy}{dx}=\dfrac{-4xy-y}{x}[/tex]

Step-by-step explanation:

[tex]\ln(xy)+4x=45[/tex]

[tex]\textsf{Apply the product log law}\quad\ln(ab)=\ln(a)+\ln(b):[/tex]

[tex]\implies \ln(x)+\ln(y)+4x=45[/tex]

[tex]\textsf{Add}\:\dfrac{d}{dx}\:\textsf{in front of each term}:[/tex]

[tex]\implies \dfrac{d}{dx}\ln(x)+\dfrac{d}{dx}\ln(y)+\dfrac{d}{dx}4x=\dfrac{d}{dx}45[/tex]

[tex]\textsf{Differentiate the}\: x \: \textsf{terms and constant terms first}:[/tex]

[tex]\implies \dfrac{1}{x}+\dfrac{d}{dx}\ln(y)+4=0[/tex]

[tex]\textsf{When differentiating with respect to}\:y,\: \textsf{differentiate and add}\: \dfrac{dy}{dx}:[/tex]

[tex]\implies \dfrac{1}{x}+\dfrac{1}{y}\dfrac{dy}{dx}+4=0[/tex]

[tex]\textsf{Rearrange to make}\:\dfrac{dy}{dx}\:\textsf{the subject}:[/tex]

[tex]\implies \dfrac{1}{y}\dfrac{dy}{dx}=-4-\dfrac{1}{x}[/tex]

[tex]\implies \dfrac{dy}{dx}=y\left(-4-\dfrac{1}{x}\right)[/tex]

[tex]\implies \dfrac{dy}{dx}=-y\left(4+\dfrac{1}{x}\right)[/tex]

If you want it in rational form, then:

[tex]\implies \dfrac{dy}{dx}=-4y-\dfrac{y}{x}[/tex]

[tex]\implies \dfrac{dy}{dx}=\dfrac{-4xy-y}{x}[/tex]

[tex]~~~~~\ln(xy) +4x = 45\\\\\\\implies \dfrac{d}{dx} \left[\ln(xy) +4x \right] = \dfrac{d}{dx} ( 45)\\\\\\\implies \dfrac{1}{xy} \cdot \dfrac{d}{dx} (xy) + 4 = 0\\\\\\\implies \dfrac 1{xy} \left( x\dfrac{dy}{dx} + y \right) +4 =0\\\\\\\implies x\dfrac{dy}{dx} + y + 4xy=0\\\\\\\implies x \dfrac{dy}{dx} =-y-4xy\\\\\\\implies \dfrac{dy}{dx} = \dfrac{-y-4xy}x[/tex]
