Find the missing angles.

Answers

Answer 1

Answer:

a=30 b=30 c= 75

Step-by-step explanation:

By inferring that all triangles are the same measurments, you can easily knock out A and B since it is the same angle that is labeled 30 degrees.

Now to find C you need to know that all angles of a triangle add up to 180 degrees. You also need to know that both bottom angles are the same angle measurement, indicated by the little circle in the angle.

So, For the middle triangle you can create an equation. 30(which was b) + 2c = 180

Subtract 30 from both sides and you are left with:

2c = 150

Divide by 2 on each side:

c= 75

Identify the constant of Proportionality Write an equation to relate weight, w, to the price, p.

Answers

Answer:

m = .45

p = .45w

______

.45 = 9/20

Explanation:

m is the rate of change equal to the price over the weight or p/w.

Because this relationship is proportional, each weight divided by its corresponding price must equal the same fraction because it is constant.

We can prove this by dividing each price by its weight to find this proportion.

1.35/3 = 2.7/6 = 27/60 = 9/20 = 0.45

1.71/3.8 = 171/380 = 9/20 = 0.45

2.34/5.2 = 234/520 = 117/260 = 9/20 = 0.45.

Since equal the same value, this means that 9/20 or .45 is our proportion.

in terms of p = mw

p/w = 9/20.

p = mw → p/w = m → m = p/w = .45 .

Thus, p = .45w,

so m = .45.

Which means that for every .45 or 9/20 w or weight, there is a price of $1.

While on a trip, you notice that the video screen on the airplane, in addition to showing movies and news, records your altitude (in kilometers) above the ground.

As the plane starts its descent
(at time x = 0), you record the following data: Time, x (min.) Altitude, y (km)
12 0 10 8 16 16 18 4 110 12

If you were to graph these points on a graph, you would notice that the line that forms represents a linear function. What is the practical meaning of slope in this situation?

a. For every minute that passes, the airplane descends 1 kilometer.
b. For every minute that passes, the airplane ascends 1 kilometer.
c. For every 2 minutes that passes, the airplane descents 1 kilometer.
d. For every minute that passes, the airplane ascends 2 kilometers. C.

For every minute that passes, the airplane descends 1 kilometer. then option a is correct.

How to find the rate of change of a linear equation?

Suppose that the considered linear equation is of the form

y=mx+c

Then, when we change x by 1 unit, then:

The rate of change is the slope. The formula for slope is

m = y2 - y1 / x2 - x1

Using the first two points, (0, 12) and (2, 10), we have

m = (10-12)/(2-0)

m = -2/2

m = -1

This means the plane descends 1 km per minute which means in 3 minutes' time, the plane descends 3 km.

Therefore, option a. For every minute that passes, the airplane descends 1 kilometer.

A patient needs a total dose of 50 grams of albumin. The pharmacy has 50 m
bottles of 25% Albumin in stock. How many bottles should the pharmacy
technician prepare to provide the required dose?

Answers

Answer : The number of bottles should the pharmacy technician prepare to provide the required dose are 4 bottles.

Step-by-step explanation :

As we are given that a patient needs a total dose of 50 grams of albumin and the pharmacy has 50 mL bottles of 25% Albumin in stock.

Now we have to determine the number of bottles should the pharmacy technician prepare to provide the required dose.

As,

The pharmacy has stock albumin = [tex]50mL\times \frac{25}{100}[/tex]

The pharmacy has stock albumin = 12.5 mL

So,

Number of bottles should the pharmacy technician prepare to provide the required dose = [tex]\frac{50}{12.5}[/tex]

Number of bottles should the pharmacy technician prepare to provide the required dose = 4

Therefore, the number of bottles should the pharmacy technician prepare to provide the required dose are 4 bottles.
