what would x equal? (x=___)

The equation that models the situation is 0.50x+7.50= 0.75(x+6)( option B)

Average cost is the ratio of the total cost to the total number of unit. It can be expressed mathematically as AC = TC/Q

where Q is the total number of unit and TC is the total cost

Cost for wooden bead = 0.5× x= 0.5x

cost for glass beads = 1.25×6 = $7.50

total cost = 0.50x+ 7.50

total unit = x+6

therefore average cost = (0.50x+7.50)/(x+6)

0.75= (0.50x+7.50)/(x+6)

therefore 0.5x+7.50 = 0.75(x+6)

therefore the equation 0.5x+7.50 = 0.75(x+6) can be used to model the situation.

Answer:

n - 8 >= 10

n minus 8 is greater than or equal to 10

Eight less than a number " n" , is at least 10.

The inequality for this condition can be represented as

\(\bold{ { n-8\geq 10}}\\\)

Hence option (2) is correct

To find out the expression for this inequality  let us consider that the number be ''n"

Since the actual number in the question is less than this number \(\rm n\) by \(8\) hence let the new number be \(\rm N\)

From the given condition in the statement  we can write that

\(\rm N = n-8\)

According to the condition given in the statement  we can write that

The value of \(\rm N\) is at least  10. This means  the minimum value for \(\rm N\) is 10.

This signifies that N can be any number with minimum value 10.

So the inequality for this condition can be represented as

\(\rm\bold{ { N\geq 10}}\\\bold{ { n-8\geq 10}}\\\)

Hence option (2) is correct

C. $452115.44

Step-by-step explanation:

To solve this, we will follow the steps below;

first write down the formula for  compound interest

A= P [ 1 + \(\frac{r}{n}\)]^nt

where A is the ending amount

P represent the principal

r represent the interest rate

n represent the number of compounding a year

t represent the time {in years)

from he question above

p= $318 000

r = 0.071

n = 4  since is quarterly

t= 5

we can now proceed to insert the values into the formula

A= P [ 1 + \(\frac{r}{n}\)]^nt

  =318 000 [1+\(\frac{0.071}{4}\)] ^4(5)

  = $318 000 [1+\(\frac{0.071}{4}\)] ^20

   =$318 000 [1+0.01775] ^20

    = $318 000 [1.01775] ^20

     =$318 000× 1.421747

      ≈$452 115.44

Answer: 45

Step-by-step explanation: Area of a triangle is l x h all divided by 2.

Plug numbers in. 9 x 10=90. 90/2 = 45.

The radius of the pipe is approximately 8.13 cm.

To find the radius of the pipe, we can use the formula for the volume of a cylinder, which relates the depth of the water, the width of the surface, and the radius of the pipe.

The volume of a cylinder is given by the formula V = π\(r^2\)h, where V is the volume, r is the radius, and h is the height or depth.

In this case, we are given the depth of the water as 18 cm and the width of the surface as 48 cm.

Since the width of the surface is equal to the diameter of the pipe, we can use the formula for the diameter of a circle, which is twice the radius.

Therefore, the radius is half of the diameter, or r = 48/2 = 24 cm.

Using the formula for the volume of a cylinder, we can write the equation as V = π\((24)^2\)(18), where V is the volume.

We know that the volume is equal to the cross-sectional area of the pipe multiplied by the depth of the water.

The cross-sectional area is given by the formula A = π\(r^2\).

Now we can solve for the radius.

Rearranging the equation V = π\((24)^2\)(18), we get

\((24)^2\) = V/(π(18))

Solving for \((24)^2\), we find that the radius is approximately 8.13 cm.

Volume of B = 8 × 80 = 640cm³

The volume of the scale factor is 8. Then the volume of the solid B will be 640 cm³.

Volume is a measurement of three-dimensional space that is utilized. It is frequently mathematically quantified using SI-derived units or different imperial or US traditional units. The concept of length is linked to the notion of capacity.

The diagram shows two similar solids, A and B. Solid A has a volume of 80 cm³.

The scale factor is given as,

Scale factor = 8 / 4

Scale factor = 2

The scale factor of the volume is given as,

⇒ 2³

⇒ 8

Then the volume of the solid B will be given as,

Volume of B = 8 x 80

Volume of B = 640 cm³

The volume of the scale factor is 8. Then the volume of the solid B will be 640 cm³.

Step-by-step explanation:

The clinic should hire at least 7 doctors in order to serve 122 patients per day.

To determine how many doctors the clinic should hire in order to serve 122 patients per day, we need to calculate the number of patients each doctor can see within their working hours.

Let's start by calculating the total number of minutes each doctor works per day. Since each doctor works 8 hours per day and there are 60 minutes in an hour, the total minutes worked by a doctor per day would be 8 hours × 60 minutes = 480 minutes.

Next, we need to find out how many patients a doctor can see within their working hours. Given that each patient requires an average of 27 minutes with a doctor, the number of patients a doctor can see per day would be 480 minutes ÷ 27 minutes per patient = 17.7778 patients.

Since we can't have a fractional number of patients, we need to round this number up to the nearest whole number to ensure that each patient gets the required attention. Therefore, each doctor can see approximately 18 patients per day.

To serve 122 patients per day, we divide the total number of patients by the number of patients each doctor can see per day: 122 patients ÷ 18 patients per doctor = 6.7778 doctors.

Again, we can't have a fractional number of doctors, so we need to round this number up to the nearest whole number. Therefore, the clinic should hire at least 7 doctors to serve 122 patients per day.

In summary, the clinic should hire at least 7 doctors in order to serve 122 patients per day.

The arc measures on the given circle are as follows, using theorems:

1. Arc CE: 148º.

2. Arc BD: 6º.

The measure of Arc CE is found applying the central angle theorem, which states that the measure in degrees of the arc is twice the measure of the inscribed angle from these points.

The measure of the inscribed angle is of m<1 = 74º, hence the measure of the arc is given as follows:

m<Arc CE = 2 x 74º = 148º.

The measure of arc BD is found applying the outside angle theorem, which states that the measure of the arc formed by two secants of the circle is half the difference of the measures of the intercepts arcs.

Hence, in the context of this problem, the measure of arc BD is obtained as follows:

34 = (74 - BD)/2

74 - BD = 68

The probability that X is between 134.4 and 140.1 is approximately 0.4076, which is closest to the option 0.4069.

To calculate this probability, we need to standardize the values using the standard normal distribution. First, we find the z-scores for the lower and upper bounds:

z1 = (134.4 - 137.0) / 5.3 ≈ -0.4906

z2 = (140.1 - 137.0) / 5.3 ≈ 0.5849

Next, we use a standard normal distribution table or a calculator to find the probabilities associated with these z-scores. The probability corresponding to z1 is P(Z < -0.4906) ≈ 0.3131, and the probability corresponding to z2 is P(Z < 0.5849) ≈ 0.7207.

To find the probability that X is between 134.4 and 140.1, we subtract the probability associated with the lower bound from the probability associated with the upper bound:

P(134.4 < X < 140.1) = P(Z < 0.5849) - P(Z < -0.4906) ≈ 0.7207 - 0.3131 = 0.4076.

As a result, the chance that X lies between 134.4 and 140.1 is roughly 0.4076, which is closest to the value of 0.4069 for the option.
