12. There are multiple correct answers. Be sure to show all your work. A team of students have built a water
powered rocket for chemistry class. Their challenge is to hit a target on the ground that is 300 feet away. They
have built a rocket that maintains a straight flight at a speed of 60 miles per hour. Once the propulsion stops, the
rocket will descend at a 67-degree angle and a speed of 15 miles per hour.
What angle should the rocket be launched at to hit the target?
How far will the rocket travel through the air?
How much time will the rocket spend in the air?

5.77 to the nearest ones decimal point is 5.8

Answer:

120/6=20

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

You would get a statistical distribution. As given in another answer, the expected value is 20. By the central limit theorem, it would approach a normal distribution with expected value of 20 (nP) and variance of 16.67 (nP(1-P)) or standard deviation 4.08.

Answer:

arc QS = 104°

Step-by-step explanation:

arc QTS = 2(128) = 256

arc QS = 360 - 256 = 104°

The measure of arc length QS is 104.

We have,

An inscribed angle is an angle whose vertex is on the circumference of a circle, and its sides are chords of the circle.

From the definition,

Inscribed angle = 1/2 x intercepted arc

Now,

128 = 1/2 x QTS

QTS = 256

Now,

QTS + QS = 360

256 + QS = 360

QS = 360 - 256

QS = 104

Thus,

The measure of QS is 104.

Answer:

[tex]b = \frac{x - 6}{x + 2} \\ b(x + 2) = x - 6 \\ bx + 2b = x - 6 \\ bx - x = - 6 - 2b \\ x(b - 1) = - 2(3 + b) \\ x = \frac{ - 2(3 + b)}{b - 1} [/tex]

Answer:

135 degrees

Step-by-step explanation:

The Triangle MNP in which m∠M = 15  and m∠N = 135 is similar to triangle ABC.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

Triangle ABC has the following angle measures:

m∠A = 15° and m∠B = 120°.

We know that the addition of the angles of a triangle makes 180°, therefore:

m∠A + m∠B + m∠C = 180°

Replacing with data and solving for x:

15 + 120 + x = 180

x = 180 - 135

x = 45°

The Triangle MNP in which m∠M = 15  and m∠N = 135 is similar to triangle ABC.

C:1

The scale factor of triangles ΔRST and ΔUVW is 1.

Option C is the correct answer.

A scale factor is defined as the ratio between the scale of a given original object and a new object,

We have,

ΔRST and ΔUVW have the same measure of the corresponding sides.

So,

RS/UV = 8/8 = 1

ST/VW = 7/7 = 1

RT/UW = 7/7 = 1

Thus,

The scale factor of ΔRST and ΔUVW is 1.

9514 1404 393

Answer:

Step-by-step explanation:

The first inequality describes a line with negative slope and y-intercept -4. The solution space is above that line.

The second inequality describes a line with positive slope and y-intercept +1. The solution space is below that line.

Together, the lines make a sort of X on the graph. The resulting solution space will be in the right-side quadrant of that X. Any sufficiently small y-value for a sufficiently large x-value will be a solution. Any point to the left of x=-4 will not be a solution. Values in each category are listed above and shown on the attached graph.

Step-by-step explanation:

Fluid Ounces would be likely to use to measure the capacity of a mug.

The unit to measure the volume of a mug is required.

The best suitable unit is fluid ounces.

Let us convert each unit to liters which will help us compare the units.

[tex]1\ \text{quart}=0.95\ \text{l}[/tex]

[tex]1\ \text{fluid ounce}=0.0296\ \text{l}[/tex]

A teaspoon is to small to measure a mug's volume, while a quart is too large.

So, the best suitable unit is fluid ounces.
