B.) f( n) = n + 3

C.) f( n) = 1/3n

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

Answer:

Subtract the original from the new to find the difference:

It was a 200% increase.

Step-by-step explanation:

Subtract the original from the new to find the difference:

148 - 74 = 74

Now divide the new by the difference:

148 / 74 = 2

Multiply that by 100 to get the percentage:

2 x 100 = 200%

explanation:Simplify Ratio 5:20

To simplify the ratio 5:20, we find the greatest common divisor of 5 and 20, and then we divide 5 and 20 by the greatest common divisor.

The greatest common divisor that you can use to simplify 5:20 is 5. Which means the answer to ratio 5:20 simplified is:

1:4

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.

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].

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.

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.

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

Approximately = 0.06

Answer:

32 free throws.

Step-by-step explanation:

It is given that,

Peter shot 40 free throws. He made 80% of his shots.

We need to find the fraction that is equivalent to 80%.

It means we have to find 80% of 40. It can be calculated as follows :

[tex]F=\dfrac{80}{100}\times 40\\\\=32[/tex]

80% of 40 is equivalent to 32 free throws.

0.5 3/5 5/8 65%

Step-by-step explanation:

Answer:

Your answer is 0.5, 3/5, 5/8, 65%.

Step-by-step explanation:

Convert all numbers to decimals:

0.5 = 0.5

5/8 = 0.625

65% = 0.65

3/5 = 0.6

Arrange the numbers accordingly: 0.5, 0.6, 0.625, 0.65. Hence, your answer is 0.5, 3/5, 5/8, 65%.

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.
