Answer:

1: 30 degrees

Step-by-step explanation:

In Physics, we have the law of reflection. This law states that when light rays hit the smooth surface of mirror or any smooth polished surface, the angle of incidence is equivalent to the angle of reflection.

Mathematically:

Angle of incidence = Angle of reflection

From the above question, the angle of incidence is on a smooth plane mirror = 30°

Since:

Angle of incidence = Angle of reflection

30° = 30°

Therefore, based on the law of reflection, the Angle of reflection = 30°

Answer:

The probability of picking a black card at random, from a deck with 3 black cards and 7 red ones is 0.3.

Step-by-step explanation:

We will assume that we have 3 black cards and 7 black cards, for a total of 10 cards. Since we are taking one card at random, we can assume that each card is equally likely to be drawn. We have the following event A: The drawn card is a black. We will find the probability of A as counting the number of outcomes that make A to occur and divide it by the total number of possibilities. We are drawing one card, so we have 10 possibilities to be picked. Out of those 10, only 3 cards are black, hence we have 3 possibilites of picking a black card.

Then,

P(A) = 3/10 = 0.3.

Answer:

1kg ghee is left behind

Step-by-step explanation:

Here, we are to calculate the amount of ghee left.

Firstly, 2/4 was consumed for preparing medicine. This is same as 1/2

The amount used in preparing medicine is thus 1/2 * 20kg = 10kg

amount remaining = 20kg - 10kg = 10kg

She also use 2/5 and 1/2 of the remainder.

The total amount used is 2/5 + 1/2 = 9/10

The amount used is thus 9/10 * 10 = 9kg

what is left is thus 10kg -9kg = 1 kg

Answer:

x ≈ 33

Answer: 12

Step-by-step explanation:

1200/750=1.6

1.6 X 8 = 12.8

12 number of  maximum people she can serve.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Amount of Apples = 750 g

and, Svetlana has 1.2 Kg of apples

So, number of people she can serve

= 1200/750 x 8

= 1.6 x 8

= 12.8

= 12 people.

Hence, 12 number of  maximum people she can serve.

Slope = 4

Step-by-step explanation:

Hi!

So, I can only see question a, so I will answer that.

This is asking for the slope given 2 points.

The line-slope formula states :

[tex]m = \frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}[/tex]

where m is the slope and the x and y values are the corresponding values from 2 coordinate points. The hard part of this is deciding which of your points is point 1 and which is point 2. It's arbitrary, so any selection is correct. We just have to stay consistent.

Let's let (3,12) be point 1 and (4,16) be point 2. Now we can write the corresponding x and y values into our formula:

[tex]m = \frac{({y_{2}-y_{1}})}{(x_{2}-x_{1})}\\m = \frac{(16-12)}{(4-3)}\\\\m = \frac{4}{1}\\\\m = 4[/tex]

So, the slope of the line through the 2 points (3, 12) and (3, 16) is 4

Answer:

The solution is [tex]x = 7[/tex],

Step-by-step explanation:

Equation:

[tex]6x - 7 + 20x + 5 = 180\textdegree[/tex]

-Combine like terms:

[tex]6x - 7 + 20x + 5 = 180\textdegree[/tex]

[tex]26x - 2 = 180\textdegree[/tex]

Add both sides by 2:

[tex]26x - 2 + 2 = 180\textdegree + 2[/tex]

[tex]26x = 182\textdegree[/tex]

-Divide both sides by 26:

[tex]\frac{26x}{26} = \frac{182\textdegree}{26}[/tex]

[tex]x = 7[/tex]

So, the answer is [tex]x = 7[/tex].

Answer:

No, -3 is greater than -24

Step-by-step explanation:

-3≤-5(3)+3(-3)

-3≤-15-9

-3≤-24

No, -3 is greater than -24

Hope this helps! Please mark brainliest :)

Answer: No

Step-by-step explanation: To find out if this ordered pair is a solution to the following inequality, simply plug the values in for x and y.

So we have -3 < -5(3) + 3(-3) or -3 < -15 + -9 or -3 < -24.

Since -3 < -24 is a false statement, the ordered pair

(3, -3) would not be considered a solution.

Answer: 65

Step-by-step explanation: In this problem, we're given that the height of a trapezoid is 10 and the bases has lengths of 9 and 24 and we're asked to find the area of the trapezoid. Since we're given the lengths of the bases, let's use our formula for the area of a trapezoid which involves the bases.

Area of a trapezoid is shown at the bottom your screen.

Now plug the information into the formula.

Simplify inside parentheses first.

Then multiply 1/2 by 10 to get 5.

Then you have (5)(13) which is 65.

So the area of the trapezoid is 65.

Answer:

320 tickets for 1200 shs and 680 tickets for 800 shs (multiply please)

Step-by-step explanation:

let; x - be the number of 1200 shs tickets.

     y - number of 800 shs tickets.

x + y = 1000 tickets........................... eqtn 1

1200x + 800y = 928000 shs.........................eqtn 2

solve the simultaneous equation by elimination by multiplying eqtn 1 by 800 and eqtn 2 by 1 to be able to eliminate (y) when subtracting.

you will get ; -400x = -12800. Cancel out to get x as 320.

use any equation to get y

i used equation 1 ; 320 + y =1000.

subtract 320 from 1000 to get 680.

multiply the number of tickets by their corresponding amount to get the answer as;

1200 sh tickets = 384000 shs

800 sh tickets = 544000 shs.

there goes your answer . you can prove it to see if it adds up. i hope i have been a great help to you.

Answer:

17.32 cm

Step-by-step explanation:

According to Viviani's theorem, the sum of the distances from an interior point to the sides of an equilateral triangle equals the height of the triangle.

In an equilateral triangle ΔABC, if U is an interior point, the sum of distances from  U to each sides of ΔABC = height of triangle. Since each side of the triangle is 20 cm, we can find the height of the triangle (h)

This can be represented by a triangle with hypotenuse 20 cm, a leg of 10 cm (20/2) and the other leg h cm. Using Pythagorean theorem:

h² + 10² = 20²

h² = 400 - 100 = 300

h = √300 = 17.32 cm

Therefore, the sum of distances from  U to each sides of ΔABC is 17.32 cm

Step-by-step explanation:

Answer:

( x + 13 )^2 +  ( y + 6 )^2 = 1; Option A

Step-by-step explanation:

~ The question we have at hand is: x^2 + y^2 + 26x + 12y + 204 = 0 ~

Let us apply the circle equation ( x - a )^2 + ( y - b )^2 = r^2 ⇒ provided r is the radius, centered at point ( a, b )

1. First rewrite x^2 + y^2 + 26x + 12y + 204 = 0 in the standard form of circle equation: x^2 + y^2 + 26x + 12y + 204 = 0

2. Now move the loose number to the right side: x^2 + 26x + y^2 + 12y = -204

3. Let us now group variables: ( x^2 + 26x ) +  ( y^2 + 12y ) = -204

4. Convert x to square form: ( x^2 + 26x + 169 ) +  ( y^2 + 12y ) = -204 + 169

5. Convert to square form: ( x + 13 )^2 +  ( y^2 + 12y ) = -204 + 169

6. Convert y to square form: ( x + 13 )^2 +  ( y^2 + 12y + 36 ) = -204 + 169 + 36

7. Convert to square form, and simplify: ( x + 13 )^2 +  ( y + 6 )^2 = 1

Answer: ( x + 13 )^2 +  ( y + 6 )^2 = 1

Answer:

1. n[(A U B) - C] = {23, 24, 27, 29, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 61, 63}

2. n[(A - B) U C] = n[A U C] = {6, 10, 12, 15, 20, 23, 29, 30, 31, 37, 41, 43, 47, 53, 59, 60, 61}

3. D. I, II and III.

Step-by-step explanation:

U = {21, 22, 23, ..., 64}

A prime number is a number that can be divided only by 1 and itself.

A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}

B = {24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63}

C = {6, 10, 12, 15, 20, 30, 60}

1. Find n[(A U B) - C]

n(A U B) = {23, 24, 27, 29, 30, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 60, 61, 63}

n[(A U B) - C] = {23, 24, 27, 29, 30, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 60, 61, 63} - {6, 10, 12, 15, 20, 30, 60}

Since only 30 and 60 are common to n(A U B) and C, we therefore remove them it and have:

n[(A U B) - C] = {23, 24, 27, 29, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 61, 63}

2. Find n[(A - B) U C]

To get n(A - B) we remove all the elements of B in A. Since there are no common elements between A and B, we therefore have:

A - B = A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}

C = {6, 10, 12, 15, 20, 30, 60}

Therefore, we have:

n[(A - B) U C] = n[A U C] = {6, 10, 12, 15, 20, 23, 29, 30, 31, 37, 41, 43, 47, 53, 59, 60, 61}

3. Which of the following is/are true?

I. A ∩ B = A ∩ C

A ∩ B = ∅

A ∩ C = ∅

Therefore, A ∩ B = A ∩ C is true.

II. A - B = A - C

A - B = A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}

A - C = A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}

Therefore, A - B = A - C is true.

III. A ∩ (B ∪ C) = ∅

A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}

B U C = {6, 10, 12, 15, 20, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63}

Therefore, A ∩ (B ∪ C) = ∅ is true.

Therefore, the correct option is D i.e. I, II and III are true.
