One third of the candidates for a job were 25 years old or younger. Two sevenths of the candidates were at least 50 years old. If 84 people applied for the job, how many were between 25 and 50?

Who prescribed the most medicine?

It would be Dr. Hong. This is because Dr. Hong has prescribed more than Dr.Tannenbaum and Dr.Evans.

Who prescribed the least?

It would be Dr.Evans. Because he has prescribed 0.02 less than Dr.Hong and 0.01 less than Dr.Tannenbaum.

Dr. Hong prescribed most medicine and Dr. Evan prescribed less medicine among all other doctors.

Further explanation:

Given:

Dr. Hong prescribed 0.019 liter more medicine than Dr. Tannenbaum.

Dr. Evans prescribed 0.02 liter less than Dr. Hong.

Calculation:

Consider Dr. Tannenbaum prescribed x liter medicine.

It is given that the Dr. Hong prescribed 0.019 liter more than the Dr. Tannenbaum.

Therefore Dr. Hong prescribed [tex]x+0.019{\text{liter}}[/tex] medicine.

It is also given that the Dr. Evans prescribed 0.02 liter less than Dr. Hong.

Therefore, Dr. Evans prescribed [tex]\left({x+0.019-0.02}\right){\text{liter}}[/tex] medicine.

So the Dr. Evans prescribed exactly [tex]\left({x-0.001}\right){\text{liter}}[/tex].

Therefore the medicine prescribed by Dr. Hong is [tex]\left({x+0.019}\right){\text{liter}}\\[/tex].

The medicine prescribed by Dr. Tannenbaum is x liters.

The medicine prescribed by Dr. Evans is [tex]\left({x-0.001}\right){\text{liter}}[/tex].

Arrange all doctors in ascending order with their prescribed medicine.

Dr. Hong > Dr. Tannenbaum > Dr. Evans

So it is obtained from the above expression that the Dr. Evans prescribed less medicine and Dr. Hong prescribed most medicine than other doctor.

Thus, Dr. Hong prescribed most medicine and Dr. Evans prescribed less medicine among all other doctors.

Answer:

the answer is A

Step-by-step explanation:

first you have to add 16+7 which is 23, then subtract 23 from 35 and you get 12, she spent 12 dollars on lunch.

First calculate the time it takes to reach the building using the x-component of the velocity.

t = 57.6 m / (42.7 m/s * cos35.2) = 1.65 s

Then we calculate the height y using the y-component of the velocity:

y = (42.7 m/s * sin35.2) * 1.65 s – 0.5 (9.81 m/s^2) (1.65 s)^2

y = 11.26 m

Final answer:

Using principles of projectile motion and given the initial speed, angle of projection, and horizontal distance, the stream of water from the fire hose will strike the building at a height of approximately 20.3 meters.

Explanation:

To determine at what height the stream of water will strike the building, we need to apply the principles of projectile motion. We are given the initial speed of the water stream (42.7 m/s), the angle of projection (35.2 degrees), and the horizontal distance from the fireman to the building (57.6 meters).

First, we separate the initial velocity into horizontal (ux) and vertical (uy) components:

ux = u * cos(θ) = 42.7 m/s * cos(35.2°) = 42.7 m/s * 0.8192 ≈ 35.0 m/s

uy = u * sin(θ) = 42.7 m/s * sin(35.2°) = 42.7 m/s * 0.5759 ≈ 24.6 m/s

Next, we use the formula for the horizontal motion to find the time (t) it takes for the water to reach the building:

x = ux* t => 57.6 m = 35.0 m/s * t => t ≈ 1.65 s

Finally, we can calculate the vertical distance (y) using the time and the vertical component of the velocity:

y = uy*t - (1/2) * g * t2 = 24.6 m/s * 1.65 s - (0.5 * 9.81 m/s2 * (1.65 s)2) ≈ 20.3 m

Therefore, the stream of water will strike the building at a height of approximately 20.3 meters above the ground.

Answer:

Step-by-step explanation:

To write the equation of the line, use the slope formula to find the slope. Then substitute the slope and a point into the point slope form. Simplify using the distributive property to write in slope intercept form.

[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{25 - 17}{7-3} = \frac{8}{4} = 2[/tex]

Using the point slope form of a line equation, substitute m = 2 and the point (3,17).

[tex]y - y_1 = m(x-x_1)\\y -17 = 2(x - 3)\\y - 17 = 2x - 6 \\ y = 2x - 6 + 17 \\ y = 2x + 11 [/tex]

Answer:

Expression representing the measure of the two angles of the given regular polygon is 16x² - 26x + 20.

Step-by-step explanation:

Given Expression of the Sum of the all interior angles of a regular polygon

40x² - 65x + 50

We need to find expression representing the measure of the two angles.

We know that regular polygons have all side and all angles equal.

Number of side or angles in regular polygon = 5

So, when we divide given expression by 5 we get expression for an angle of the regular polygon.

[tex]\frac{40x^2-65x+50}{5}=\frac{5(8x^2-13x+10)}{5}=8x^2-13x+10[/tex]

Expression for an angle of regular pentagon = 8x² - 13x + 10

Now, For 2 angles  = 2( 8x² - 13x + 10 ) = 16x² - 26x + 20

Therefore, Expression representing the measure of the two angles of the given regular polygon is 16x² - 26x + 20.

Step-by-step explanation:

The reasonable estimate for multiplying 94 by 689 is found by rounding the numbers to the nearest convenient figures, which gives an estimated result of 70,000.

To estimate the product of 94 and 689, you can round each number to its nearest simple form and then multiply. Round 94 to 100 because it is close to that multiple of ten. Round 689 to 700, as it is close to this hundred mark. When you multiply 100 by 700, you get 70,000.

This process of rounding to the nearest convenient number simplifies the multiplication and gives us an answer that is easy to calculate and understand. Hence, by rounding the numbers before multiplying, the reasonable estimate for the problem 94 · 689 is 70,000.

Final answer:

By rounding the numbers and multiplying, a reasonable estimate for the product of 94 and 689 is 70,000.

Explanation:

To estimate the product of 94 · 689, we can round the numbers to the nearest ten or hundred and then multiply. For estimation purposes, we can approximate 94 to 100 (since it's closer to 100 than 90) and 689 to 700 (since it's closer to 700 than 600).

Multiplying these rounded figures: 100 × 700 equals 70,000. Therefore, 70,000 is a reasonable estimate for the product of 94 and 689.

Answer:

Hence, the monthly payment to the nearest cent is 510.31

Step-by-step explanation:

Consider the provided information,

A college student borrow ​$1,500 for 3 months to pay for a semester of school.

Let us consider the monthly payment is $x.

If he pay $x for next 3 months, then the total amount student paid in 3 month is: 3x

The interest is ​$30.94 for 3 months.

Student pay all the borrowed money and interest in 3 months.

That means he pay $1,500 + $30.94 in 3 months while the monthly payment was 3x.

This can be written as:

[tex]3x = 1500+30.94[/tex]

[tex]3x = 1530.94[/tex]

[tex]x = \frac{1530.94}{3}[/tex]

[tex]x = 510.31[/tex]

Hence, the monthly payment to the nearest cent is 510.31

Final answer:

The baker's revenue R can be expressed as R = x * 6.50, and the cost C can be expressed as C = 45 + 25 + (x * 1.75). To find the number of cakes he needs to sell before making a profit, we set the revenue equal to the cost and solve for x. The baker will need to sell at least 15 cakes before making a profit.

Explanation:

To express the revenue R as a function of x, we can use the equation R = x * 6.50. This is because the revenue is the number of cakes sold multiplied by the price per cake. So, every cake sold contributes $6.50 to the revenue.

To express the cost C as a function of x, we can use the equation C = 45 + 25 + (x * 1.75). The initial fixed costs of $45 for reserving a booth and $25 for traveling expenses are added to the variable costs of $1.75 per cake multiplied by the number of cakes sold.

To find the number of cakes he needs to sell before making a profit, we need to set the revenue equal to the cost and solve for x:

R = C => x * 6.50 = 45 + 25 + (x * 1.75)

Combining like terms, we get:

4.75x = 70

x = 70 / 4.75

x ≈ 14.74

Since you cannot sell a fraction of a cake, the baker will need to sell at least 15 cakes before making a profit.
