A construction crew is paving a road. The crew has already paved 1,000 square feet and can pave at a rate of 300 square feet of road per hour. The function f(x) = 300x

Answers

Answer 1

Answer:

Step-by-step explanation:

i go to southwind what’s the answer ??

Answer 2

The crew would spend 3.33 hours to pave a road that is 1,000 ft².

A linear equation is in the form:

y = mx + b;

where y, x are variable, m is the slope of the line and b is the y intercept.

Let f(x) represent the amount of space paved in x hours.

Given the function:

f(x) = 300x

Therefore to pave 1000 ft²:

1000 = 300x

x = 3.33 hours

The crew would spend 3.33 hours to pave a road that is 1,000 ft².

6. The graph shows the number of soda bottles a machine can make over time. Use the two points (2, 50) (6, 150) shown to find the number of soda bottles the machine can make
per minute.

Step-by-step explanation:

25 soda bottles the machine can make per minute.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

We have to use the two points (2, 50) (6, 150) shown to find the number of soda bottles the machine can make per minute.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

x₁=2, y₁=50, x₂=6, y₂=150

substitute in slope formula

Number of soda bottles=slope=150-50/6-2

=100/4

=25

Hence 25 soda bottles the machine can make per minute.

The licensed practitioner has ordered gemcitabine 400 mg/m^2 IV for a patient whose BSA is 0.47 m^2. You have on hand a 200 mg vial of gemcitabine for injection that contains 38 mg per mL. How much medication should this patient receive?

Answers

Answer:

4.95 mL

Step-by-step explanation:

Since we have 400 mg/m² of gemcitabine for a patient whose BSA is 0.47 m², the mass of drug required for the patient is thus m = 400 mg/m² × 0.47 m² = 188 mg.

Also, since 200 mg vial of gemcitabine for injection that contains 38 mg per mL, so the concentration of gemcitabine is 38 mg/mL.

Since concentration = mass/volume, and

volume = mass/concentration,

the volume of gemcitabine injection required is

V = mass of gemcitabine/concentration of gemcitabine in injection

V = 188 mg/38 mg/mL

V = 4.95 mL

Find the height of an equilateral triangle whose perimeter is 24

Answers

Answer:

[tex]h = 4\sqrt{3}[/tex]

Step-by-step explanation:

If the triangle is equilateral, it means that all the sides are the same. Since there are 3 sides in a triangle, each side is 24/3 = 8

Now, in order to find the height, we can use the pythagoeren theroem. Notice that the height bisects(splits the side) into two equal parts, which each part having the length 8/2 = 4

So we have [tex]h^2 + 4^2 = 8^2[/tex]

[tex]h^2 = 48[/tex]
