The Triangles Shown Below Must Be Congruent.303055OA. TrueO B. False

Answers

Answer 1
False. You need to graphically turn the triangle and see if it matches. It’s a trick question, the legs don’t match. They switched the position of the 5 on each triangle and the legs are 100% not equal (30-60-90 triangle).

Note: if the question was changed to 45 degree angle (45-45-90) instead of the famous (30-60-90) then they would be congruent because both legs of each triangle would be 5. In other words the 45 degrees tells us the legs are equal on every triangle but the 30-60-90 triangle tells us 100% the legs must be different.

what is 457.894 to 2 deimal places

Answers

Answer:

228.947

Step-by-step explanation:

Answer:

457.894

Step-by-step explanation:

"What is 457.894 rounded to 2 decimal places?" is the same as asking, "What is 457.894 rounded to two decimal points?" or "How to round 457.894 to two decimal places."

The main point is that you want to round 457.894 to two digits or places after the decimal point. Thus, we want to eliminate the last digit in 457.894. To eliminate the last digit in 457.894, we use the following Two Decimal Places Rules to get the answer:

Two Decimal Places Rule #1: If the last digit in 457.894 is less than 5, then remove the last digit.

Two Decimal Places Rule #2: If the last digit in 457.894 is 5 or more and the second to the last digit in 457.894 is less than 9, then remove the last digit and add 1 to the second to the last digit.

Two Decimal Places Rule #3: If the last digit in 457.894 is 5 or more and the second to the last digit in 457.894 is 9, and the third to the last digit is less than 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the third to the last digit.

Two Decimal Places Rule #4: If the last digit in 457.894 is 5 or more and the second to the last digit is 9, and the third to the last digit is 9, then add 1 to the number on the left side of the decimal point and make the right side of the decimal point 00.

When rounding 457.894 to two decimal places we use Two Decimal Places Rule #1. Therefore, the answer to "What is 457.894 rounded to 2 decimal places?" is:

457.89

Perform these transformations on △DEF.
Reflect △DEF across the x-axis and label the resulting image△D'E'F'.
Rotate △D'E'F' 90° clockwise about the origin and label the resulting image △D''E''F''.
Translate △D''E''F'' according to (x,y)→(x-2,y+2) and label the image △D'''E'''F'''.

Answers

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If a point A(x, y) is reflected across the x axis, the new location is at A'(x, -y).

If a point A(x, y) is rotated 90° clockwise about the origin, the new location is at A'(y, -x).

If a point A(x, y) is translated a units left and b units up, the new location is at A'(x-a, y+b).

From the image attached, the location of triangle DEF is D(2, 6), E(2,3) and F(5, 3).

If △DEF is reflected across the x-axis, the resulting image △D'E'F' is at D'(2, -6), E'(2, -3) and F'(5, -3).

If △D'E'F' is rotated 90° clockwise about the origin, the resulting image △D''E''F'' is at D''(-6, -2), E''(-3, -2) and F''(-3, -5).

If △D''E''F'' is translated by (x,y)→(x-2,y+2), the resulting image △D'''E'''F''' is at D'''(-8, 0), E'''(-5, 0) and F'''(-5, -3).

Solve the following simultaneous equations
y=x^2
y= x+6

Answers

The required solution of the given simultaneous equations are x = 2, 3 and y = 3,9.

What are simultaneous equation?

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Now the given simultaneous equations are,

y = x^2    ...(i)

y = x + 6  .....(ii)

Equating (i) and (ii) we get,

x^2 = x + 6

or, x^2 - x - 6 = 0

Solving we get,

x^2 - 3x - 2x - 6 = 0

⇒ x(x - 3) -2(x - 3) = 0

⇒ (x - 2)(x - 3) = 0

So, x = 2, 3

Putting x = 2, 3 in equation (i) we get,

y = 2^2

⇒ y = 4

and,

y = 3^2

⇒ y = 9

Thus, y = 3,9

Thus the required solution of the given simultaneous equations are x = 2, 3 and y = 3,9.

The longer leg of a right triangle has a length of 15. One angle in the triangle is 60 degrees. What is the length of the shortest leg?

Answers

The shortest side of a right triangle with a hypotenuse of 15 and one angle of 60° is 7.5

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Given that the longer leg of a right triangle has a length of 15, hence hypotenuse = 15. One angle in the triangle is 60°. Let x represent the shortest side.

The shortest side is adjacent to the 60° angle, hence:

cos(60) = x / 15

x = 7.5

The shortest side of a right triangle with a hypotenuse of 15 and one angle of 60° is 7.5

Step-by-step explanation:

Answer:

False.

Step-by-step explanation:

Tobacco use not only affects the person using it but also those around them. Secondhand smoke is the smoke that is exhaled by a smoker or that comes from the burning end of a cigarette, cigar, or pipe. Secondhand smoke contains more than 7,000 chemicals, including hundreds that are toxic and at least 70 that can cause cancer. Breathing in secondhand smoke can lead to a range of health problems, especially in children and non-smoking adults. These can include lung cancer, heart disease, stroke, respiratory infections, and asthma. Additionally, exposure to secondhand smoke during pregnancy can cause low birth weight, premature birth, and sudden infant death syndrome (SIDS). Therefore, it is important to create smoke-free environments to protect the health of everyone, including non-smokers.
