Answer:

3p + 26  

Step-by-step explanation:

Let S = Sue's newspapers sold

     B = Bill's newspapers sold

     H = Harry's newspapers sold.

We have three conditions:

(1)   S = B + 26

(2)  B = 3H

(3)  H = p     Substitute (3) into (2)

(4) B = 3p     Substitute (4) into (1)

      S = 3p + 26

Sue sold 3p + 26 newspapers.

Step-by-step explanation:

Basically, in each option, you have to find the relationship between x and y (for one pair). Like in option #1 - how do you get 1.5 from 3? divide it by 2. Now you apply it for all numbers. It the outcome the same? No. 7 ÷ 2 ≠ 3.

You do the same process for all, until you are left with the last one. y = 50x

Let's keep in mind the conversion factors between mile, yard, feet and inches:

1 mile = 1760 yards

1 yard = 3 feets

1 feet = 12 inches

a) 3 mi. 26 yd.

We have:

8 mi. 133 yd. 2 ft. –

5 mi. 107 yd. 2 ft =

Here, we can simply do the substraction of each term, and we get:

(8-5) mi  (133-107) yd  (2-2) ft =

3 mi. 26 yd  0 ft =

3 mi. 26 yd.

b) 2 yd. 7 in.

We have:

2 yd. 2 ft. 6 in. –

0 yd.  1 ft. 11 in.

Here, we need to convert 1 feet into 12 inches and add them to the inches in the first term as follows:

2 yd. 2 ft. 6 in. = 2 yd. 1 ft. (6+12) in. = 2 yd. 1 ft. 18 in.

So now the subtraction becomes:

2 yd. 1 ft. 18 in. –

0 yd.  1 ft. 11 in.

and now we can simply do the substraction of each term, and we get:

(2-0) yd.  (1-1) ft.  (18-11) in. =

2 yd. 0 ft. 7 in. =

2 yd. 7 in.

c)  5 yd. 5 in.

We have:

6 yd.  0 ft. 0 in. –

0 yd.  2 ft. 7 in.

We have to "move" 1 yard into  feets and inches in the first term, as follows:

6 yd.  0 ft. 0 in. = 5 yd. 3 ft. 0 in. = 5 yd. 2 ft. 12 in.

And now the subtraction becomes:

5 yd. 2 ft. 12 in. -

0 yd.  2 ft. 7 in. =

5 yd.  0 ft. 5 in. =

5 yd. 5 in.

d) 8 in.

We have:

8 yd. 0 ft. 4 in. –

7 yd. 2 ft. 8 in.

Again, let's convert the first term, moving yards into feets and inches:

8 yd. 0 ft. 4 in. = 7 yd. 3 ft. 4 in. = 7 yd. 2 ft. (4+12) in. = 7 yd. 2 ft. 16 in.

So now the subtraction is:

7 yd. 2 ft. 16 in. -

7 yd. 2 ft. 8 in. =

0 yd. 0 ft. 8 in. =

8 in.

Answer:

69% or 69/100

Step-by-step explanation:

It's experimental odds based off of experience.

The probability of getting a head on the next flip is 69%.

In order to determine the probability of getting a head on the next flip, we must first analyze the given data. The number of heads obtained in the first 100 flips is 69, while the number of tails is 31. Based on this information, we can calculate the proportion of heads to the total number of flips. The probability of getting a head on the next toss is therefore 69/100 = 0.69 or 69%.

Answer:

306

Step-by-step explanation:

9 times 18= 162

24 times 6= 144

144+162=306

Answer:

150 and 240 are the two numbers having difference as 90 and ratio as 5 : 8.

Step-by-step explanation:

Since ratio of two numbers is 5 : 8 ,

lets assume two numbers be 5x and 8x.

Difference of two numbers = 8x - 5x = 90

⇒3x =90

⇒x = 90/3=30

so two numbers are 5x = 5 × 30 = 150 and 8x = 8 × 30 = 240

Hence 150 and 240 are the two numbers having difference as 90 and ratio as 5 : 8.

The probability that a randomly selected light bulb will last between 750 and 825 hours is 34.13%. This is calculated through standardization of the desired range into z-scores, and reference to the standard normal distribution table.

The question is about finding the probability that a randomly selected light bulb will last between 750 and 825 hours, given that the life of light bulbs is normally distributed with a mean of 750 hours and a standard deviation of 75 hours.

Firstly, standardize the desired range by subtracting the mean and dividing by the standard deviation. This will give us the z-score: Z = (X - μ) / σ. For X = 750, Z1 = (750 - 750) / 75 = 0. For X = 825, Z2 = (825 - 750) / 75 = 1.

We can then use the Z-table or standard normal distribution table to find the probability associated with these z-scores. Since the z-score for 750 is 0, the probability is 0.5 (or 50%, as it's the mean). For z=1, the probability is 0.8413 (or 84.13%).

The probability that the bulb will last between 750 and 825 hours is then calculated by subtracting the smaller probability from the larger one: 0.8413 - 0.5 = 0.3413 or 34.13%

#SPJ12

To find the probability, calculate the z-scores for the values and use the standard normal distribution table which is 34.13%

To find the probability that a randomly selected light bulb will last between 750 and 825 hours, we need to calculate the z-scores for both values and then use the standard normal distribution table. The z-score is calculated using the formula:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation. For 750 hours, the z-score is 0, and for 825 hours, the z-score is (825 - 750) / 75 = 1.

Using the standard normal distribution table, the probability corresponding to a z-score of 0 is 0.5, and the probability corresponding to a z-score of 1 is 0.8413.

Therefore, the probability that a randomly selected light bulb will last between 750 and 825 hours is 0.8413 - 0.5 = 0.3413, or 34.13%.

Answer:

The angle 6 measures 54 degrees

Step-by-step explanation:

Angle 6 is congruent to angle 7 ("-2x+34") as it is an opposite angle in straight line intersection. But angle 6 is congruent to angle 2 (-9x-36) due to the two horizontal lines being parallel. So we can write the following equality to determine the value of x:

-2x + 34 = -9x -36

7x = -70

==> x = -10

Now we can answer the question:  the angle 6 is

-2x + 34 = -2(-10)+34 = 54 degrees

The required values of x and y is 9 and -36, respectively. The correct answer is option a.

Given that the system of equations:

y = -3x - 9                       (1)

y = (1/3)x - 39                  (2)

Setting the two equations equal to each other since they both equal y:

-3x - 9 = (1/3)x - 39

⇒ -3(3x) - 3(9) = (1/3)(3x) - 39(3)

⇒ -9x - 27 = x - 117

⇒ -9x - x = -117 + 27

⇒ -10x = -90

⇒ x = -90 / -10

⇒ x = 9

Substitute the value of x back in the equation (1),

y = -3(9) - 9

⇒ y = -27 - 9

⇒ y = -36

Hence, the solution to the system of equations is x = 9 and y = -36. The correct answer is option a.

Answer:

The value of the quantity after 186 hours is 2089.41

Step-by-step explanation:

We can use exponential formula

[tex]P(t)=a(1-b)^{\frac{t}{h} }[/tex]

a quantity with an initial value of 2100

so,

[tex]a=2100[/tex]

decays exponentially at a rate of 0.65% every 10 days

So, b=0.0065 when h=10*24=240

now, we can plug values

[tex]P(t)=2100(1-0.0065)^{\frac{t}{240} }[/tex]

now, we can plug t=186

and we get

[tex]P(186)=2100(1-0.0065)^{\frac{186}{240} }[/tex]

[tex]=2089.413[/tex]

Answer:

Q(186)  = 2089.463                    

Step-by-step explanation:

Formula for decaying exponentially:

Q(t) = Q_0 e^{-rt}

where, Q(t)= quantity at time t

Q_0 = initial quantity value (2100)

t = time (186 hours)

r = rate of decaying (0.65)

r = 0.65% = 10 days

1 day = [tex]\frac{0.0065}{10}[/tex]

1 hour = [tex]\frac{0.0065}{240}[/tex]

186 hours = [tex]\frac{0.0065*186}{240}[/tex]

rt = 0.00503

Q(186) = 2100*e^{-0.00503}

Final answer:

The man originally had $99. We determined this by setting up an equation based on the remaining amount after spending and misplacing portions of his money, then we solved for the original total.

Explanation:

To solve for the original amount of money the man had, let's call that amount x. First, he spent two-thirds of his money, which is (2/3)x. The remainder is x - (2/3)x = (1/3)x. He then misplaced one-third of this remainder which is (1/3) of (1/3)x = (1/9)x. So the portion he was left with is (1/3)x - (1/9)x = (2/9)x.

Since we know the final amount left is $22, we can express this as an equation:

To find x, we will divide both sides of the equation by (2/9):

When dividing by a fraction, we multiply by its reciprocal which is (9/2):

Therefore, the man originally had $99.

Answer:

y = 36

Step-by-step explanation:

log4 (y – 9) + log4 3 = log4 81.

We know from the property of logs that if the bases are the same, when we subtract logs, we can divide what is inside

loga (b) + loga (b) = loga (b*c)

Lets simplify the expression log4( (y-9)*3) = log4 (81)

Since the bases are the same, what is inside the parentheses on the left hand side  must be equal to what is inside the parentheses o the right hand side

(y-9)*3 = 81

Divide each side by 3

(y-9)*3 /3= 81/3

y-9 = 27

Add 9 to each side

Answer:

x coordinate is 2

Step-by-step explanation:

We have given,

9x - 8y = 2   .........(1)

-3x - 9y = -24   ...............(2)

We use elimination method to eliminate y.

We multiply equation (1) by 9 and equation (2) by 8.

We get,

{ 9x - 8y = 2} × 9   or  81x - 72y = 18    -------------(3)

{-3x - 9y = - 24} × 8  or -24x - 72y = -192  -----------(4)

And subtract equation (4) from equation (3)

So , (81x - 72y ) - (-24x -72y)= 18 -(-192)

or 105x = 210

or x = 210/105

or x= 2

Hence we get x coordinate as x= 2
