Answer 1

Answer:

m∠a = 50°

Step-by-step explanation:

Since this is an isosceles triangle, we know that the other unknown angle is also 65°. Since all angles in a triangle add up to 180°,

180 - 65(2) = a

a = 180 - 130

a = 50°

Answer 2

Answer:

a = 50

Step-by-step explanation:

In an isosceles triangle, two angles are equal. In this triangle, the base angles are equal.

65 + 65 + a = 180

Angles in a triangle add up to 180 degrees.

130 + a = 180

a = 180 - 130

a = 50

Find the acute angle between the sides of a rhombus whose diagonals are 8cm and 12cm long

Answers

Answer:

67.38°

Step-by-step explanation:

The diagonals of a rhombus intersect at their midpoints and make a right angle. They also divide the angles of the rhombus in two equal angles.

So, to find the acute angle of the rhombus, we can use the tangent relation of half this angle in the small triangle made when drawing the diagonals:

tan(angle/2) = 4 / 6

tan(angle/2) = 0.666

angle/2 = 33.69

angle = 67.38°

So the acute angle of the rhombus is 67.38 degrees.

Write your own word problem and share it with the group. Then translate your problem into its resulting math equation. What steps would you then follow to solve for the variable?

Answers

Step-by-step explanation:

Word Problems are mathematical problems presented in complete languages, rather than in mathematical notations.

Example:

A certain number is divided by half, the result is added to itself to give 6, what is the number?

Solution:

- Let the number be x

- Divide x by half:

In word problem, extra caution is to be taken, as misinterpretation can be very chaotic. Dividing a number by 2, is totally different from dividing the number by half.

4 divided by 2 is 4÷2 = 2

4 divided by half is 4÷½ = 4×2/1 = 8

2 and 8 are different, reason to be cautious.

So dividing x by half, we have:

x ÷ 1/2 = x × 2/1 = 2x.

- Now, what we have is

2x + x = 6

Solving this equation, we can obtain the value of x.

2x + x = 6

3x = 6

Dividing both sides by 3

3x/3 = 6/3

x = 2.

Therefore, the solution to the word problem is x = 2.

Which of the following is an example of dependent events? A. Drawing a jack from a standard deck of cards and then drawing a six without replacing the jack B. Winning the lottery and getting struck by lightning C. Spinning a 5 on a spinner and getting tails from flipping a coin D. Owning a dog and being in the school chorus

Answers

Answer:  A. Drawing a jack and drawing a six without replacement

Step-by-step explanation:

A Dependent event means the outcome of one event affects the outcome of the other event.

Options B, C, and D:

The first event is completely unrelated to the second event so those options are Independent events.

Option A:

The first event uses 52 cards.  The second event only has 51 cards remaining because we did not replace the first card.  The probability of the second event IS affected by the first event so this is a Dependent event.

Note: If the card was replaced before drawing the second card, then it would be an Independent event.

The example for dependent events is (A) Drawing a jack from a standard deck of cards and then drawing a six without replacing the jack.

What are Dependent Events?

If the probability of one event of two events is affected by another one then that two events are called dependent events of one another.

What is Probability?

The probability of an event is the ratio of the favorable cases for that event to the total number of possible cases under that event.

Here analyzing the given choices we get,

(A) If we draw a jack from a standard deck of cards that is containing 52 cards.

And then we draw a six replacing without that jack card then it affects the probability as the total number of cards for this event reduces from 52 to 51.

So these two events are dependent events.

(B) Winning a lottery and getting struck by lighting are completely two different events from a different field, so they are independent.

(C) Spinning a 5 on a spinner cannot affect getting tails from flipping a coin. So they are not dependent on events.

(D) Owning a dog cannot affect being in the school chorus so they are independent (not dependent).

Hence the correct answer is (A).

Step-by-step explanation:

Surface area:

Area of base = 14 x 10 = 140

area of slope x 2 = 25 x 10 x 2 = 500

Total surface area = 500+140+336 = 640 + 336 = 973cm^2

Which of the following theorems verifies that ABC~WXY?

Answers

Answer:

ABC~WXY by AA

Step-by-step explanation:

In ΔABC

∠B = 90°

∠A = 27°

To Find ∠C

Angle sum property: The sum of all angles of triangle is 180°

∠A+∠B+∠C=180°

27°+90°+∠C=180°

∠C=180°-117°

∠C=63°

In ΔWXY

∠X = 90°

∠Y = 63°

We will use angle sum property

So, ∠W+∠Y+∠X=180°

90°+63°+∠W=180°

∠W=180°-(90°+63°)

∠W=27°

So, ∠A=∠W

∠B =∠X

∠C = ∠Y

So, ABC~WXY by Angle - Angle property.

Hence ABC~WXY by AA

Line MN passes through points M(4, 3) and N(7, 12). If the equation of the line is written in slope-intercept form, y = mx + b, what is the value of b? 1. -15 2. -9 3. 3 4. 9

Answers

Answer:

-9

Step-by-step explanation:

What b represents here is the y intercept.

The first thing we will do here is to find the slope.

Mathematically;

m = (y2-y1)/(x2-x1)

Plugging the values;

m = (12-3)/(7-4) = 9/3 = 3

The equation can thus be written as;

y = 3x + b

To get b, we can use any of the points since they lie on the line

Let’s use point M

Substitute the values of x and y in the equation

3 = 3(4) + b

3 = 12 + b

b = 3-12 = -9

Answer:

B) -9

g(x) = 4 - 2x + 12

Step 2: Combine like terms

g(x) = -2x + 16

The system of the equation that represents the given condition will be x + y = 7 and y = x + 3. And the solution is (2, 5).

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The sum of x and y is 7. The value of y is three more than the value of x. Then the equation is given as,

x + y = 7                ...1

y = x + 3               ...2

From equations 1 and 2, then we have

x + x + 3 = 7

2x = 4

x = 2

Then the value of the variable 'y' will be given as,

y = 2 + 3

y = 5

The system of the equation that represents the given condition will be x + y = 7 and y = x + 3. And the solution is (2, 5).

10x= 22. 67676767

1000x= 2267. 676767

1000x-10x= 2267.676767- 22.67676767

990x= 2245x= 2245/990x= 449*5/5*198x= 449/198 x= 2 53/198

Answer:

Step-by-step explanation: First, create an equation that represents the repeating decimal that you want to convert to a fraction

x = 2.267267....      (1)

There are 3 repeating decimals, multiply both sides of the equation by 103 = 1000 so that both equations have the same repeating digits to the right of the decimal point

1000x = 2267.267267...      (2)

Subtract the equation (1) from equation (2)

1000x

x =

2.267267...

999x = 2265

Solve for the x in the equation to determine the equivalent fraction.

x =

2265

999

Since the greatest common factor of 2265 and 999 is 3, we can simplify the fraction and show the same amount

2265

999

=

2265 ÷ 3

999 ÷ 3

=

755

333

Therefore, 755/333 is simplified fraction of 2.267 repeating. Since this is an improper fraction, converted to mixed number is:

755

333

= 2

89

333

Therefore, 2.267 repeating as a fraction is 755/333 and It is written as 2 89/333 in mixed number form.

What are the asymptote and the Y intercept of the function shown in the graph f(x)=3(0.2)^x+2

Answers

the asymptote is y = 2 and the y - intercept is (0,5)

What is asymptote function?

An asymptote is a line that the graph of a function approaches as either x or y go to positive or negative infinity. There are three types of asymptotes: vertical, horizontal and oblique. That is, as approaches from either the positive or negative side, the function approaches positive or negative infinity.

According to the question

The function reaches the y-axis at the point (0,5).

The asymptote is the line that the function follows but never quite reaches. In this case, the function follows the path of y = 2. However, it never exactly fits the line.

The y-intercept is (0,5) and the asymptote is y = 2. The answer, then, is B.

Hence, the asymptote is y = 2 and the y - intercept is (0,5)
