Determine the type of triangle that is drawn below.

Answer:

57.14°

Step-by-step explanation:

A 5m ladder reaches 4.2m up a wall. What angle does the ladder make with the wall?

We solve the above question using the Trigonometric function of Sine

= sin theta = Opposite/Hypotenuse

Opposite = Length of the wall = 4.2m

Hypotenuse = Length of the ladder = 5m

Theta = Angle formed = x

Hence,

sin x = 4.2m/5m

x = arc sin(4.2m/5m)

x = arc sin(0.84)

x = 57.140119621°

Approximately = 57.14°

Using the constant of proportionality, the value of  when y is 3.25 is 0.5 from the inverse variation.

An rise in one variable causes a decrease in the other and vice versa in a mathematical relationship between two variables known as inverse variation, also known as inverse proportionality or inverse relationship. The following equation represents inverse variation:

y = k/x

In this equation, "y" and "x" stand in for the two variables, and "k" is the variational constant. Throughout the connection, the constant of variation has a set value that never changes.

Using the data given;

y = kx

Let's find the value of k;

k = constant of proportionality

13 = k(2)

k = 13/2

k = 6.5

Using the value of k;

3.25 = 6.5x

x = 3.25 / 6.5

x = 0.5

NB: The options given are incorrect and if you will follow through the steps, you will understand the options are incorrect.

-plug in earbuds or put on headphones, you dont have to play/listen to anything, but it helps block out noise

-maybe set a small goal for yourself, where if you get a class or quiz or whatever done, you go do something else that you enjoy for a few minutes and think of a new goal for the next class.

-sometimes actually playing music tends to help! at least to me

-it can be hard, but try your best to work on only your current assignment until your done with that one. nothing else.

-(if you do it at home) go into a silent room, like maybe yours, and close the door. take out anything that might distract you, like electronics.

-if you do this at home and use your computer/a computer and tend to go onto other websites for an hour instead of working, it might be best to ask someone to block those websites on your computer. thats the most major thing i can think of...

If consider the Pythagorean Theorem and its converse. A, C, D, and E are correct statements.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

In this case, statement A is correct because 6, 8, and 10 are possible side lengths for a right triangle.

Statement B is incorrect because 10, 15, and 20 are not possible side lengths for a right triangle.

Statement C is correct because the Pythagorean Theorem works only for sides of a right triangle.

Statement D is correct because if the sides of a right triangle are of lengths 8 and 15, its hypotenuse is 17.

Statement E is correct because the converse of the Pythagorean Theorem allows us to calculate the side lengths of right triangles.

Thus, the correct statements would be options A, C, D, and E.

Answer:

$17.88

Step-by-step explanation:

Freddy earns = $750 per week

Has 3 dependents

and he is single

Tax rate = 3%  

Lets calculate Freddy's Annual Taxes and Taxable income

Freddy's Annual income = 750 *52 = $39,000

Annual Allowance for a single person = $2000

Annual allowance for 3 dependents = $2000 * 3 = $6000

Hence Freddy's Annual Taxable Income = ( 39000 - 8000 ) = $31,000

Annual withheld tax = 3% * $31,000 = $930

Therefore Freddy's weekly withheld tax = 930 / 52 = $17.88

Answer:

He must start his journey by 11 AM

Step-by-step explanation:

Speed of Toshi while walking up the mountains is 1.5 kilometres per hour

Speed of Toshi while walking down  the mountains = 2 * Speed of Toshi while walking up the mountains = 3 kilometres per hour

Time taken to travel 9 Km in the upward direction by Toshi = 9 Km/1.5 kilometres per hour = 6 hours

Time taken to travel 9 Km in the downward direction by Toshi = 9 Km/3 kilometres per hour = 3 hours

He will take total 6 hours + 3 hours = 9 hours to travel 18 Km distance

Thus, He must start his journey by 11 AM

Step-by-step explanation:

False. A parabola is not defined as all points equidistant from a given directrix and focus.

A parabola is a conic section defined as the set of all points that are equidistant from a fixed point called the focus and a fixed line called the directrix. In other words, for any point on a parabola, the distance to the focus is equal to the perpendicular distance to the directrix. This property is known as the geometric definition of a parabola.

The focus and directrix are essential elements in defining a parabola, but they do not solely define it. The shape of a parabola is determined by the distance between the focus and the directrix. Varying this distance results in different sizes and orientations of parabolas.

The specific equation of a parabola incorporates the coordinates of the focus, the directrix, and a parameter called the focal length to precisely describe its form. False is the answer.

Good luck!!

Answer:

1 1/5 cups

Step-by-step explanation:

Write and solve an equation of ratios here.  Let x be the amount of butter needed if 3 cups of flour are used.  Then, comparing the quantities of butter first (in the first column) and the quantities of flour second, we get the ratio

  x                3 cups

------------- = -------------

(4/5) cup       2 cups

Cross-multiplying, we get:

2x = 12/5, or x = 6/5

You'll need 6/5 cups of butter, or 1 1/5 cups, if you're using 3 cups of flour.

[tex]\huge\boxed{C)\ 12}[/tex]

Step-by-step explanation:

The three interior angles in a triangle will always add up to 180°.

Therefore

[tex]59+(6x-10)+59=180\\(59+59-10)+6x=180\\108+6x=180\qquad|\text{subtract 108 from both sides}\\10-10+6x=180-108\\6x=72\qquad|\text{divide both sides by 6}\\\dfrac{6x}{6}=\dfrac{72}{6}\\\boxed{x=12}[/tex]

Answer:

Option C

The value of x is 12°

Step-by-step explanation:

Here, we know that in a Triangle The sum of all three angles is 180°.

Now,

59° + 59 + (6x - 10)° = 180°

118° + 6x - 10° = 180°

6x + 108° = 180°

6x = 180° - 108°

6x = 72°

x = 72° ÷ 6

x = 12°

Thus, The value of x is 12°
