Answers

Answer:

9 : 1

Step-by-step explanation:

Let the correct answers be denoted by C.

Let the incorrect answers be denoted by I.

Given the following data;

Correct answers = 45 answers

Incorrect answers = 50 - 45 = 5 answers

Ratio of correct to incorrect answers;

C : I = 45 : 5

Dividing by 5, we have;

of one leg equal to 9 centimeters and
the length of the hypotenuse equal to
15 centimeters, what is the length of
the other leg?
F 6 cm
H square root of 306 cm
G 12 cm
J 144 cm

Answers

Answer:

G. 12 cm

Step-by-step explanation:

Length of one leg of right triangle = a = 9 cm

Length of hypotenuse = c = 15 cm

Length of the other leg = b = ?

Applying pythagorean theorem, c² = a² + b², we have:

15² = 9² + b²

15² - 9² = b²

144 = b²

b = √144

b = 12

Answers

Answer:

m<ABC = 116°

m<CDE = 67°

Step-by-step explanation:

✔️m<ABC = 180 - m<BAD (adjacent angles of a parallelogram are supplementary)

m<ABC = 180 - 64° (Substitution)

m<ABC = 116°

✔️m<CDA = m<CDE + m<ADE (angle addition postulate)

m<CDA = m<CDE + 49°

m<CDA = m<ABC (opposite angles of a parallelogram are congruent)

m<CDE + 49° = 116° (substitution)

m<CDE = 116° - 49° (Substraction property of equality)

m<CDE = 67°

2m+(m-15)=90 solve for m

Answers

Answer:

m = 35

Step-by-step explanation:

2m + m -15 = 90

3m -15 = 90

     +15  +15

3m = 105

/3     /3

m = 35

To check the work just insert 35 for m:

2(35) + 35 -15 = 90

70 + 35 -15 = 90

105 - 15 = 90

90 = 90

Make an algebraic expression to determine the 15th term of this pattern:
63, (63+23), (63+23+30), (63+23+30+37), ...

And please, give me a complete answer with a step-by-step explanation.

Answers

Answer:

63+23+30+37+44+51+58+65+72+79+86+93+100+107+114.

Step-by-step explanation:

1. according to the condition 63+23; 63+23+30; 63+23+30+37+...; is an arithmetic sequence (note, 63 does not belong to it);

2. according to the condition the 1st term is 63+23; the 2d term is 63+23+30; the 3d term is 63+23+30+37, etc. It means, the next term is calculated with '+7';

3. according to the item '1.' the number '63' was excluded from the initial pattern. It means, the 14th term should be calculated: 23+7*(14-1)=114.

4. if number '63' is included into the given pattern again, the 15th term of the given pattern is 63+0+23+30+...+98.

5. the 15th term is:

63+23+30+37+44+51+58+65+72+79+86+93+100+107+114.

Consider the following equation

3x + 9y = 8y - 2

Step 2 of 2: Find the equation of the line which passes through the point (13,5) and is perpendicular to the given line. Express your answer in
slope-intercept form. Simplify your answer.

Answers

Answer:

The perpendicular line is:

y = 1/3  x + 2/3

Step-by-step explanation:

The given equation can be reduced to its slope-intercept form as shown below:

3x + 9y = 8y - 2

subtract 8 y from both sides

3 x + y = -2

subtract 3 x from both sides

y = - 3 x -2

therefore we know that the slope of this line is -3, and then, a perpendicular line to it must have slope given by the "opposite of the reciprocal" of this slope. That is, the slope of any perpendicular line to this one must be: 1/3

We use this slope to find the equation of the line passing through the point (13. 5)

y = 1/3 x + b

passing through (13, 5) means:

5 = 1/3 (13) + b

therefore, we can find b from the above equation

b = 5 - 13/3 = 15/3 - 13/3 = 2/3

Then the equation of this perpendicular line is:

y = 1/3  x + 2/3

Bar graph Please select the best answer from the choices provided Passage: What Causes Earthquakes Natural earthquakes occur mostly from tectonic movements of the plates. Tectonic plates are large parts of the oceanic and continental lithosphere. The lithosphere is the solid outer section of Earth's crust. These sometimes shift into various positions both under water and above. Such movements generally occur along fault lines. When two rocks slide against each other, they create fault lines. These fault lines can be both extremely narrow or miles wide. Fault lines are created mostly in mountainous regions where plate tectonic movements are more likely. Movement between the tectonic plates is rarely smooth. When the plates slide against each other, they create a tremendous amount of friction. This friction forms seismic energy that travels in waves through the surface of the Earth. This causes the earthquake. While normal energy travels above the surface of the Earth, seismic energy travels under the Earth's surface. This creates more tension between the land plates, causes more shifting, and creates more fault lines. The spot below the Earth's surface where the rocks break against each other is called the focus of the earthquake. The place exactly above the focus on the surface of the planet is called the epicenter of the earthquake. Sometimes, earthquakes can also be man-made instead of natural. These can sometimes be caused due to explosions underground. Explosions big enough to cause a shift in the surface of the Earth are generally caused in mining tunnels or during nuclear testing. But the seismic energy formed due to these explosions is rarely very strong. Therefore, the strength of the earthquakes caused is not very high.Question: In What Causes Earthquakes," which detail supports the idea that friction exists between the plates underground? A. Fault lines are created mostly in mountainous regions where plate tectonic movements are more likely. B. Movement between the tectonic plates are rarely smooth. C. When two rocks slide against each other, they create fault lines. D. Explosions big enough to cause a shift in the surface of the Earth are generally caused in mining tunnels or during nuclear testing.
