Answer:

Please send a clearer image so I can answer question 1 and 3

Step-by-step explanation:

2: "One of the parallel lines can be translated so that it lands on the other line. After that, you would notice that the angles of the two lines have exactly the same measurement. Therefore, the interior and exterior angles of two parallel lines cut by transversal are equal."

5: The angles congruent to <8 are <6, <4, and <2

6: The value of m<6 = 70°

7: The equation to find <8 = 180 - <1

   The measure m<8 = 85°

8: The value of x must be equal to 34

Work Shown:

y+47 = 90

y = 90-47

y = 43

Given :-

To find:-

Answer:-

Firstly as we know that the measure of a straight line is 180° . The given line is made up of 3 angles , which are 47° , y° and one right angle i.e. 90°.

So the sum of all these angles will be 180° as these are the angles of a straight line.

So that,

[tex]\implies 47^o + y^o + 90^o = 180^o\\[/tex]

[tex]\implies 137^o + y^o = 180^o \\[/tex]

[tex]\implies y^o = 180^o-137^o\\[/tex]

[tex]\implies \underline{\underline{ y = 43}} \\[/tex]

Hence the value of y is 43 .

and we are done!

The degrees in radian measures of the angle is 240 degrees or 4.188 radians.

The central angle of a circle is the angle formed by two of its radii. the two places on either side of the circle where the radii meet.

The angle measure between two consecutive numbers on a clock is 360/12 = 30 degrees.

At 2 the clock hand is at 2, the angle is:

30(2) = 60 degrees.

At 10, the angle is:

30(10) = 300 degrees

The angle between 2 and 10 is:

300 - 60 = 240 degrees.

Hence, the degrees in radian measures of the angle is 240 degrees or 4.188 radians.

In circle Y, the measure of m∠SZT is equal to: B. 94°.

In Mathematics, a chord of circle can be defined as a line segment that typically join any two (2) points of a circle.

Generally speaking, the inscribed angle of a circle is equal to half of the central angle of a circle. Mathematically, this is given by this mathematical expression:

m∠STR = 1/2(SYR)

m∠STR = 1/2(50)

m∠STR = 50°.

m∠TSU = 1/2(TYU)

m∠TSU = 1/2(72)

m∠TSU = 36°.

For m∠SZT, we have the following:

m∠SZT = 180° - (m∠STR + m∠TSU)

m∠SZT = 180° - (50 + 36)

m∠SZT = 180° - 84°

With the values sin x= 3/5 and sin y= 2/3 , where x and y are both in first quadrant, then after calculation sin(x + y) = (3 * √(7/9)) / 5 + 1/2.

To evaluate sin(x + y), we can use the identity sin(a + b) = sin a cos b + cos a sin b.

Given that sin x = 3/5 and sin y = 2/3, we have:

sin(x + y) = sin x cos y + cos x sin y

          = (3/5) * √(1 - (2/3)^2) + (√(1 - (3/5)^2)) * (2/3)

          = (3/5) * √(7/9) + (4/5) * (2/3)

          = (3 * √(7/9)) / 5 + (8/15)

          = (3 * √(7/9)) / 5 + (8/15)

          = (3 * √(7/9)) / 5 + (16/30)

          = (3 * √(7/9)) / 5 + (1/2)

          = (3 * √(7/9)) / 5 + 1/2

A pin can contain 3 numerical digit and no digit can be repeated. To calculate the amount of pins possible, we use 3! (3 factorial), which is 3x2x1, equaling 6. Then, we multiply this by 10, as there are 10 digits, 0-9. Therefore, 6x10 = 720. In order to calculate 3! (3 factorial) we start by multiplying 3x2x1. This is because each digit has to be multiplied by the number of digits before it, as no digit can be repeated. The first digit has no digits before it, so it stays as 3. The second digit has one digit before it, so it is multiplied by 2. The third digit has two digits before it, so it is multiplied by 1. Therefore, 3x2x1 = 6. Then, we multiply 6 by 10, as there are 10 digits, 0-9. 6x10 = 720, which means there are 720 possible pins with no digit being repeated.

If a woman's uncle has Lesch-Nyhan syndrome and her father carries the mutation, the probability of her first son being affected is 50%.

Lesch-Nyhan syndrome is an X-linked recessive genetic disorder, which means it is caused by a mutation on the X chromosome and is passed down through families primarily from affected fathers to their daughters. The probability that a son of a woman with an affected uncle (mother's brother) will be affected depends on the genetic status of the woman's father and the mother's X chromosome that she inherited from her mother.

If the woman's father does not carry the mutation, she will not carry the mutation herself and cannot pass it on to her children. In this case, the probability of her first son being affected is 0%.

If the woman's father carries the mutation, she has a 50% chance of inheriting the mutated X chromosome from her father and a 50% chance of inheriting a normal X chromosome from her mother. In this case, if the woman is a carrier of the mutation, her first son has a 50% chance of inheriting the mutation from her and being affected.

It's important to note that this is a simplified answer and that more complex genetic testing and counseling may be necessary to determine the specific risk in a particular family.

Answer: 0.4

Step-by-step explanation:

1/25 = 0.04 which is also 4% (.04 * 100)

A reasonable number of pages Carlos can write in 5 hours is between 20 and 25 pages.

Therefore the answer is C.

First, we need to find the average number of pages Carlos can write in one hour by dividing the number of pages he can write in 3/4 hour by 3/4:

(3 to 4 pages) / (3/4 hour) = 4 to 5.33 pages per hour

So, we can see that Carlos can write between 4 to 5.33 pages in an hour.

Next, we'll multiply that number by 5 to find the number of pages he can write in 5 hours:

(4 to 5.33 pages/hour ) * 5 hours = 20 to 26.65 pages

Since we can say that, he reads between 20 and 26 pages.

Therefore, the reasonable number of pages Carlos can write in 5 hours is between 20 and 25, which corresponds to option C.

Answer: At 12:00 p.m., the minute hand points straight up at (0,10).

At 12:05 p.m., the minute hand has rotated 30 degrees clockwise. The tip of the minute hand would be approximately:

x = 10 * cos(30) = 8.66

y = 10 * sin(30) = 5

So, the coordinates would be approximately (8.66, 5).

At 12:45 p.m., the minute hand has rotated 180 degrees. The tip of the minute hand would be approximately:

x = 10 * cos(180) = -10

y = 10 * sin(180) = 0

So, the coordinates would be approximately (-10, 0).

At 12:55 p.m., the minute hand has rotated 330 degrees clockwise. The tip of the minute hand would be approximately:

x = 10 * cos(330) = -5.77

y = 10 * sin(330) = -8.66

So, the coordinates would be approximately (-5.77, -8.66).

A polynomial in standard form that represents the area of paper that can be painted is equals to the x² - 48x + 540.

We have, a painter wants to painting on a paper. He starts with a blank piece of rice paper with dimensions 30 inch by 18 inch .

The total length of paper, l = 30 inch

Total width of paper , w = 18 inch

Area of paper = l× w = 18× 30

= 540 inch²

Now, painter wants to leave a uniform border.

The width of border = x inches

length of border = x inches

and paint the remaining paper. So, the length of paper which is painted = l - x

= (30 - x) inches

Width of paper which is painted = w - x = ( 18 - x) inches

Now, the painted area of paper, A = painted length × painted width

= (30 - x)( 18- x)

= 540 - 18 x - 30x + x²

= x² - 48 x + 540

which is a standard polynomial form of painted area.

Answer:

Step-by-step explanation:

To solve the inequality 56x - 13 > 113, you can start by isolating the variable on one side of the inequality. Subtract 113 from both sides:

56x - 113 > 0

Next, add 113 to both sides:

56x > 113

Finally, divide both sides by 56:

x > 2

So the solution is x > 2, meaning that x can be any value greater than 2.

The value of x and y are 25 and 25√3 respectively.

Trigonometric functions are defined as the real functions which are simply the functions of an angle of a triangle. They are basically the periodic functions which relate an angle in a right angled triangle to the ratios of the length of two sides.

Given a right angled triangle and an angle 30°.

Length of hypotenuse = 50 units

Sine of an angle in a right angled triangle is the ratio of opposite side to hypotenuse.

sin (30°) = x / 50

x = sin (30°) × 50

x = (1/2) × 50

x = 25 units

Cosine of an angle in a right angled triangle is the ratio of adjacent side to hypotenuse.

cos (30°) = y / 50

y = cos (30°) × 50

y = (√3 / 2) × 50

y = 25√3 units

Hence the value of x is 25 units and the value of y is 25√3 units.

and

∠G = ∠Y

The sum of angles is given as:

∠D + ∠G + ∠Y + ∠R = 360

Substitute values for ∠D, ∠G, ∠R

5/2 ∠Y + 5/2 ∠Y + ∠Y + ∠Y = 360

Multiply both sides by 2/14,

∠Y = 51.43

So:
