y=-19/12x+17/12

Step-by-step explanation:

Write in slope-intercept form,y=mx+b

The equation i.e. 19x + 12y = 17 equivalent to the  [tex]y = \frac{19}{12}x + \frac{17}{12}[/tex].

Given that,

Based on the above information, the calculation is as follows:

19x + 12y = 17

Here we need to solve it for y

[tex]y = \frac{19}{12}x + \frac{17}{12}[/tex]

Therefore, we can conclude that the first option is correct.

Answer: the number must be placed in the box is 9

suppose: the number must be placed in the box is x

have:

5u + 3(4u - 6) = -3u -27 + 20u + x

⇔ 5u + 12u - 18 = -3u - 27 + 20u +x

⇔ 17u + 3u - 20u = -27 + 18 + x

⇔ 0 = x - 9

⇔ x = 9

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Simplifying both sides gives 

17u - 18 = 17u - 27 + ▢.

Subtracting 17u from both sides gives

-18 = -27 + ▢. 

If the number in the box is anything but 9, then the equation cannot be true, and the original equation has no solutions. If the number in the box is 9, then the two sides of the original equation are equivalent, and all values of u are solutions to the equation.

Answer:

125yd

option b is correct

The height of the arch from the ground will be 125 yards.

Given information:

An architect is designing a commemorative steel arch in the shape of a parabola.

Parabola is vertically placed and its legs are 300 yards apart.

The focus of the parabola is 80 yards above the ground.

Let a be the distance of focus from the vertex of the parabolic arch.

So, the equation of parabola will be,

[tex]x^2=-4ay[/tex]

Assume the origin is placed on the vertex of the parabola.

So, the coordinates of the legs will be,

(-150, -(80+a)) and (150, -(80+a))

Satisfy the above point with the equation of parabola as,

[tex]x^2=-4ay\\150^2=4a(80+a)\\a^2+80a-5625=0[/tex]

Solve the above quadratic equation as,

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\a=\dfrac{-80\pm\sqrt{80^2+4\times 1\times5625}}{2}\\a=\dfrac{-80\pm170}{2}\\a=-125, 45[/tex]

The value of a can't be negative. So, [tex]a=45[/tex].

So, the height of arch will be,

[tex]80+a=80+45\\=125\rm\;yd[/tex]

Therefore, the height of the arch from the ground will be 125 yards.

Given:

Cost of the trip to get into the park = $19.99

Brady bought a hot dog for $3.50 and spent $2.10 on gas money.

To find:

The total money Brady spend.

Solution:

It is clear that,

Total money he spend = Cost of the trip to get into the park + Cost of a hot dog + Amount he spent on gas money

On substituting the values, we get

Total money he spend = $19.99 + $3.50 + $2.10

                                      = $25.59

Therefore, the total money Brady spend is $25.59.

Answer:

a) 0.71

b) 0.06

Step-by-step explanation:

We solve using Baye's Theorem

It is estimated that 88% of senior citizens suffer from sleep disorders and 7% suffer from anxiety. Moreover, 5% of senior citizens suffer from both sleep disorders and anxiety.

We have Two events

A and B

Events A = 88% of senior citizens suffer from sleep disorders

P(A) = 0.88

Event B = 7% suffer from anxiety

P(B) = 0.07

Moreover, 5% of senior citizens suffer from both sleep disorders and anxiety.

P(A and B) = 0.05

a)Given that a senior citizen suffers from anxiety, what is the probability that he or she also suffers from a sleep disorder? Round your answer to the nearest hundredth.

This is calculated as:

P(A and B)/P(B)

= 0.05/0.07

= 0.7142857143

Approximately = 0.71

B) Find the probability that a senior citizen suffers from anxiety, given that he or she has a sleep disorder. Round your answer to the nearest hundredth.

This is calculated as:

P(A and B)/P(A)

= 0.05/0.88

= 0.0568181818

Answer:

7/50 meter

Step-by-step explanation:

Total piece of string = 7/8 meter

Used string = 1/5 of the piece of string

Used string =

1/5 of 7/8 meter

= 1/5 × 7/8

= 7/40 meter

Balance = Total string - used string

= 7/8 - 7/40

= 35-7/40

= 28/40

Balance = 28/40 meter

cuts the rest into 5 equal parts. What is the length of the pieces.

28/40 ÷ 5

= 28/40 × 1/5

= 28 / 200

= 7/50 meter

Length of each piece = 7/50 meter

Given:

Value of Gift card = $50

Each time she visits the coffee shops she spends $3.75 on her favorite drink.

To find:

The equation for the given situation.

Solution:

Let x be the number of times she visits the coffee shop, and y be the total amount on her gift card.

Cost of her favorite drink for one time = $3.75

Cost of her favorite drink for x times = $3.75x

Value of gift card is $50. So,

Amount on her gift card = 50 - Cost of her favorite drink for x times

[tex]y=50-3.75x[/tex]

Therefore, the required equation is [tex]y=50-3.75x[/tex].

The circumference of the circular swimming pool is given by C = 47.12 feet

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the circumference of the circular swimming pool be C

Now , the diameter of the swimming pool D = 15 feet

So , the radius of the circular pool r = D / 2

The radius r = 7.5 feet

Now , circumference of circle = 2πr

So , on simplifying , we get

The circumference of the circular swimming pool C = 2π ( 7.5 )

The circumference of the circular swimming pool C = 15π

The circumference of the circular swimming pool C = 47.12 feet

Hence , the circumference of the circular swimming pool is 47.12 feet
