Question
Match the number with the most specific correct description.

Answer: Let's denote the original number of pages Mark planned to read as "P".

From the first statement, we know that P - 18 pages will take 5 more days, which means P pages will take 5 days less, or 5 - 5 = 0 days.

From the second statement, we know that P - 24 pages will take 8 more days, which means P pages will take 8 days less, or 8 - 8 = 0 days.

So, we have two equations:

P - 18 = 5 * X

P - 24 = 8 * Y

Where X and Y are the number of pages Mark reads per day.

Since X and Y are equal, we can substitute one of them for the other:

P - 18 = 5 * (P - 24) / 8

Expanding the right side and solving for P, we find that P = 288 pages.

The volume of the conical hole will be 154 cubic feet.

The area a cone takes up in a three-dimensional plane is known as its volume. A cone's base is circular, so it is made of a radius and a diameter.

Given that a cone-shaped hole is 3 feet deep and the circumference of the base of the hole is 44 feet,

The volume of the cone will be calculated as:-

Volume = (1/3)πr²h

The circumference of the cone is,

2πr = 44

2 x ( 22 / 7 ) x r =  44

r = 7 feet

The volume of the cone will be calculated as:-

Volume = (1/3)πr²h

Volume = ( 1 / 3 )  x ( 22 / 7 ) x 7 x 7 x 3

Volume = 22 x 7

Volume = 154 cubic feet

Therefore, the volume will be 154 cubic feet.

The skid marks would be approximately 1.9 ft in length to the nearest foot.

The drag factor of the road is given as 0.97 and the braking efficiency as 90%. To calculate the skid marks, we need to use the coefficient of friction (μ) between the tires and the road surface. The formula for calculating this is: μ = (2 x Drag Factor x Efficiency) / 100.

Therefore, μ = (2 x 0.97 x 0.9) / 100 = 0.0174

Once we have the coefficient of friction, we can use the following equation to calculate the skid marks: Skid Length = Initial Speed x Reaction Time x 0.5 x μ.

Since the speed is given as 35 mi/h and the reaction time is assumed to be 0.75 seconds, the skid marks will be: Skid Length = 35 mi/h x 0.75 s x 0.5 x 0.0174 = 1.9 ft

Therefore, the skid marks would be approximately 1.9 ft in length to the nearest foot.

Answer:

x = 49

Step-by-step explanation:

We can find the sum of the interior angles of a polygon using the formula

[tex]S_{n}=(n-2)*180[/tex], where n is the number of sides the polygon has.

Because the figure in the picture is a trapezoid and has four sides, we can find the sum of all the interior angles in the polygon by substituting 4 for n:

[tex]S_{4}=(4-2)*180\\ S_{4}=2*180\\S_{4}=360[/tex]

Since we know that the sum of all the angles in the trapezoid is 360, we can find x by subtracting the sum of the angles already given from 360:

[tex]x+118+104+89=360\\x+311=360\\x=49[/tex]

Step-by-step explanation:

Assuming all the electricians work at the same rate, we can use the formula:

(time x workers) = constant

So, if 2 electricians took 5 days, we have:

(5 x 2) = (time x 10)

Simplifying, we get:

10 = time x 10

Dividing both sides by 10, we get:

time = 1

Therefore, it would take 10 electricians 1 day to wire the house.

As per the figure, the angle equation p + q + r = 180 is proved.

In geometry, an angle is defined as the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. When two lines are parallel, the angles opposite to each other are called corresponding angles.

In the given figure AB || CD, we are asked to prove that the sum of angles p, q, and r is equal to 180 degrees. This can be proven using the concept of corresponding angles.

Since lines AB and CD are parallel, the angles opposite to each other are equal, i.e., p = r. Therefore, the sum of angles p and r can be represented as 2p.

Furthermore, since lines AB and CD are parallel, the alternate interior angles are equal. This means that angle q is equal to angle p.

Therefore, the sum of all three angles, p, q, and r, can be represented as 2p + q.

And since we know that p = q, we can simplify this to 3p.

Finally, since the sum of angles in a triangle is always 180 degrees, we know that

=> 3p = 180 degrees.

Solving for p, we find that p = 60 degrees.

Therefore, the sum of angles p, q, and r is equal to

=> 2p + q = 2 * 60 + 60 = 180 degrees,

which proves the statement p + q + r = 180 degrees.

If the rates are the same ones, the tank will be filled in 15 minutes.

Let's define R as the rate at which we fill the tank, we know that we can fill a volume V in 6 minutes, then:

R*6 min = V

R = V/6min

Then r is the rate at which we empty the tank, we know that a volume V is emptied in 10 minutes, then:

r*10 min = V

r = V/10min

If both valves are open, the rate at which we will fill the tank is:

R - r

Now we need to find the value of time T such that:

(R - r)*T = V

(V/6min - V/10min)*T = V

(1/6min - 1/10min)*T = 1

(5/30min - 3/30min)*T = 1

(2/30 min)*T = 1

T = (30min/2)

The probability of having an IQ score below the minimum Mensa IQ is 0.98, or the probability of having an IQ score above or equal to the minimum Mensa IQ is 0.02.

The features of the normal distribution can be used to determine the minimal IQ required to join Mensa if we assume that IQ scores follow a normal distribution. We can determine the IQ score that represents the 98th percentile of the IQ distribution because Mensa members make up the top 2% of all IQs.

We can determine the z-score for the 98th percentile using a typical normal distribution table, which is roughly 2.33. This indicates that the IQ score that is 2.33 standard deviations above the mean IQ is the minimal IQ required to join Mensa.

The formula: can be used if we are aware of the mean and standard deviation of the IQ distribution.

IQ equals (z-score) x standard deviation plus mean.

to determine the Mensa membership cutoff IQ. We are unable to determine the actual IQ score since the question does not include the mean or standard deviation of the IQ distribution.

The following is the probability statement for this issue:

P(IQ minimum Mensa IQ) = 0.02, or P(IQ minimum Mensa IQ) = 0.98, in other words. This indicates that the likelihood of having an IQ score below the minimum Mensa IQ is 0.98 and the likelihood of having an IQ score equal to or higher than the minimum Mensa IQ is 0.02.

D. $128.94. is the total amount of money Nate will earn after taxes when he buys a CD for $1000  The formula for compound interest is:

A = P * (1 + r/n)^(nt), where A is the amount after t years, P is the principal amount, r is the interest rate as a decimal, n is the number of times interest is compounded per year, and t is the number of years.

We can use this formula to calculate the amount of money Nate will have after 5 years:

A = 1000 * (1 + 0.03/4)^(4 * 5) = 1000 * (1 + 0.0075)^20 = 1000 * 1.1629 = 1162.9

The interest earned is 1162.9 - 1000 = $162.9.

And the amount of interest taxed is 20% of $162.9, which is 20% * $162.9 = $32.58.

So, the total amount of interest earned after taxes is $162.9 - $32.58 = $130.32.

Step 1: Calculate the initial number of hospitals. In 2000, there were 5,727 hospitals, so the initial number of hospitals (H0) is 5,727.

Step 2: Calculate the rate of change. From 2014 to 2017, the number of hospitals decreased by 156. Therefore, the rate of change (r) is -156.

Step 3: Calculate the equation. The equation for the number of hospitals H in this country t years since 2000 is H = H0 + rt. Substituting in the values from Steps 1 and 2, this gives us H = 5,727 – 156t.

Therefore, the equation for the number of hospitals H in this country t years since 2000 is H = 5,727 – 156t.
