Paul to Ava salaries ratio is 3:4. If Paul's salary is $87,000, what is Ava's salary?​

First, you must find the total number of people. Add together 32, 54, 78, 112, and 96 to get 372. Next, add the number of diabetic patients with the number of patients with eye problems (54 + 112 = 166).

Your fraction is now 116/372. Simplify this to get your answer, 29/93 or 0.31.

Answer:

θ = 240

and

cos(θ) = -0.5

Step-by-step explanation:

Theta is in the third quadrant, that meansit goes from 180 to 270 degrees

Then,

cos^2 (θ) =1/4

cos (θ) = ± 1/2

θ = arccos(0.5)

θ = 60

But in the third quadrant

θ = 180 + 60  = 240

θ = 240

and

cos(θ) = -0.5

Answer: square centimeters

Step-by-step explanation:

Hi, the answer to the question is square centimeters.

The lengths of the picture are in centimeters. So, when you calculate the area of the picture that is a triangle you obtain square centimeters.

Mathematically speaking:

20cm x 15 cm =  300 square centimeters

By multiplying the same unit you obtain the square unit.

For this case we must solve the following linear equation:

[tex]- \frac {1} {4} x + 5 = \frac {3} {4}[/tex]

Subtracting 5 from both sides of the equation we have:

[tex]- \frac {1} {4} x = \frac {3} {4} -5\\- \frac {1} {4} x = \frac {3-20} {4}\\- \frac {1} {4} x = - \frac {17} {4}[/tex]

Multiplying by 4 on both sides of the equation:

[tex]-x = -17[/tex]

Multiplying by -1 on both sides of the equation we have:

[tex]x = 17[/tex]

Answer:

[tex]x = 17[/tex]

Answer: [tex]x=17[/tex]

Step-by-step explanation:

You need to solve for the variable "x":

The first step is to subtract 5 from both side of the equation, then:

[tex]-\frac{1}{4}x+5-5=\frac{3}{4}-5\\\\-\frac{1}{4}x=-\frac{17}{4}[/tex]

The final step is to multiply both sides of the equation by -4.

Therefore, the value of the variable "x" is the following:

[tex](-4)(-\frac{1}{4}x)=(-\frac{17}{4})(-4)\\\\x=17[/tex]

Answer:

y-intercept is 4.

Step-by-step explanation:

Given,

Equation of the line,

[tex]y=\frac{4}{3}x+1[/tex]

∵ Equation of a line is y = mx + c, where m is the slope of the line,

By comparing,

The slope of the above line is [tex]\frac{4}{3}[/tex],

Let m' is the slope of the line perpendicular to above line,

[tex]\implies m'\times \frac{4}{3}=-1[/tex]

[tex]\implies m' = -\frac{3}{4}[/tex]

Now, the equation of a line passes through a point [tex](x_1,y_1)[/tex] is,

[tex]y-y_1=m(x-x_1)[/tex]

So, the equation of the perpendicular line having slope [tex]-\frac{3}{4}[/tex] and passes through ( 4,1) is,

[tex]y-1=-\frac{3}{4}(x-4)\implies y=-\frac{3}{4}x+3+1\implies y=-\frac{3}{4}x+4[/tex]

For y-intercept,

x = 0,

⇒ y = 4

Hence, the y-intercept of the perpendicular line is 4.

Answer:

(2,1)

Step-by-step explanation:

So the first thing you want to do is substitute. You want to plug in the equation for y in for the y value above.

So you would do 3x+4(x-1)=10. As you can see we took the bottom equation and put it in for the top equation. We did this so we only have x s and no y s.

Now you would solve. You would distribute first. You would get 3x+4x-4=10. Now combine like terms. 3+4 is 7 so you would get 7x-4=10.The next thing you want to do is get the 7x by itself so move the 4.You would get 7x=14. Now divided both sides by 7 because you want to get the x by itself.

You would get x=2. Now for the y value just plug it in for an equation above. The easier one would be y=x-1. y=(2)-1 will equal 1. You write your final answer in (x,y) style. Your final answer will then be (2,1)

Answer:

Step-by-step explanation:

[tex]\left\{\begin{array}{ccc}3x+4y=10&(1)\\y=x-1&(2)\end{array}\right\\\\\text{Substitute (2) to (1):}\\\\3x+4(x-1)=10\qquad\text{use the distributive property}\\3x+4x-4=10\qquad\text{add 4 to both sides}\\7x=14\qquad\text{divide both sides by 7}\\x=2\\\\\text{put the value of x to (2):}\\\\y=2-1\\y=1[/tex]

[tex]\displaystyle\frac{16-9}{(-3)-1}=\frac{7}{-4}=-\frac{7}{4}[/tex]

We're looking for a model of the form

[tex]y=a\cos(b(x-c))+d[/tex]

[tex]a[/tex] is the amplitude, equal to half the difference between the maximum and minimum hours of daylight:

[tex]a=\dfrac{15.3-9.1}2=3.1[/tex]

[tex]b[/tex] determines the period of the cosine function. The period itself is [tex]\dfrac{2\pi}b[/tex], which we want equal to 365, so that

[tex]365=\dfrac{2\pi}b\implies b=\dfrac{2\pi}{365}[/tex]

(so that the value in the second box should be 365)

[tex]c[/tex] determines the horizontal shift of the cosine function. We'll come back to this in a moment.

[tex]d[/tex] represents the vertical shift of the function. The standard function is bounded between -1 and 1:

[tex]-1\le\cos x\le1[/tex]

Our new function has an amplitude of 3.1, so that

[tex]-3.1\le3.1\cos x\le3.1[/tex]

We want the range of values to fall between 15.3 and 9.1, so we want to pick [tex]d[/tex] such that

[tex]\begin{cases}-3.1+d=9.1\\3.1+d=15.3\end{cases}\implies d=12.2[/tex]

So the current model is

[tex]y=3.1\cos\left(\dfrac{2\pi}{365}x\right)+12.2[/tex]

[tex]c[/tex] represents the horizontal shift of the function. [tex]x=0[/tex] represents the first day of the year, which according to the current model tells us we should expect [tex]3.1\cos0+12.2=15.3[/tex] hours of daylight on the first day of the year. But this conflicts with the data. We want this maximum to occur on the 172nd day of the year, so we shift the model by this amount, and the model is

[tex]y=\boxed{3.1}\cos\left(\dfrac{2\pi}{\boxed{365}}}(x-\boxed{172})\right)+\boxed{12.2}[/tex]

Answer:

Since, when a function f(x) is reflected across x-axis then resultant function is -f(x), and reflected across y-axis then resultant function is f(-x),

Also, In translation of f(x),

If the transformed function is,

g(x) = f(x+a)

If a is positive then function is shifted a unit left,

If a is negative then function is shifted a unit right,

While, if transformed function is,

g(x) = f(x) + a

If a is positive then function is shifted a unit up,

If a is negative then function is shifted a unit right,

Answer:

The length of the rectangular park is [tex]1.2\ mi[/tex] and the width of the rectangular park is [tex]0.3\ mi[/tex]

Step-by-step explanation:

Let

x ----> the length of the rectangular park

y ---> the width of the rectangular park

we know that

The perimeter is equal to

[tex]P=2(x+y)[/tex]

[tex]P=3\ mi[/tex]

so

[tex]3=2(x+y)[/tex] -----> equation A

[tex]x=4y[/tex] ----> equation B

substitute equation B in equation A and solve for y

[tex]3=2(4y+y)[/tex]

[tex]3=10y[/tex]

[tex]y=0.3\ mi[/tex]

Find the value of x

[tex]x=4(0.3)=1.2\ mi[/tex]

therefore

The length of the rectangular park is [tex]1.2\ mi[/tex] and the width of the rectangular park is [tex]0.3\ mi[/tex]

Final answer:

To determine the dimensions of a park with a 3-mile perimeter where the length is 4 times the width, we set up the equation 3 = 2l + 2w, substitute l = 4w into it, and solve for width and length. The calculations show the park is 1.2 miles long and 0.3 miles wide.

Explanation:

The student has asked for help to find the dimensions of a rectangular-shaped park with a 3-mile perimeter where the length is 4 times the width. To solve this, we will use the formula for the perimeter of a rectangle P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.

Since we know the perimeter is 3 miles, we can set up the equation 3 = 2l + 2w. Because the length is 4 times the width, we can also say that l = 4w. Substituting into the first equation, we get 3 = 2(4w) + 2w, which simplifies to 3 = 10w. To find the width, we divide both sides by 10, resulting in w = 0.3 miles. Then, using l = 4w, we find that the length l is 1.2 miles.

Therefore, the dimensions of the park are 1.2 miles long and 0.3 miles wide.

The simplified formula for calculating the monthly lease payment for a car is the sum of the depreciation fee and the finance fee. These are calculated based on the car's initial cost, residual value, and the lease factor.

In the context of car leasing, the simplified formula used to calculate the monthly lease payment is: depreciation fee + finance fee. The depreciation fee is calculated by subtracting the car's expected residual value at the end of the lease from its initial cost (MSRP) and then dividing this by the number of months in the lease. The finance fee is calculated as the sum of the MSRP and the residual value, multiplied by the lease factor or money factor which is essentially the interest rate.

The answer is:

The airplane will travel 8800 feet in 10 seconds.

It's a conversion exercise, we need to be careful in order to solve it with no mistakes.

First:

We need to remember that 1 hour is equal to 60 minutes, and 1 minute is equal to 60 seconds, so, to calculate how many seconds are in one hour, we need to perform the following operation:

[tex]Time=1hour*\frac{60minutes}{1hour}*\frac{60seconds}{nminute}=3600seconds[/tex]

Second:

We need to convert from miles to feet, we need to remember that 1 mil is equal to 5280 feet.

So, solving we have:

[tex]Speed=600\frac{miles}{hour}*\frac{1hour}{3600seconds}*\frac{5280ft}{1mile}=880\frac{ft}{seconds}[/tex]

Now, calculating how many feet does it travel in 10 seconds, we have:

[tex]distance=speed*time\\\\distance=880\frac{ft}{seconds}*10seconds=8800ft[/tex]

We have that the airplane will travel 8800 feet in 10 seconds.
