Step-by-step explanation:

Let E be the event of drawing a disc from the box of discs numbered from 1 to 90

Two digit numbers from 1 to 90=10,11,12,.....,90

No. of favorable outcomes=81

Total no. of possible outcomes =90

We know that, Probability P(E) =(Total no.of possible outcomes)(No.of favorable outcomes)=9081=109

Therefore, the probability of a two digit numbered disc from the box of discs numbered from 1 to 90=109

Answer:

14-8

12-9

0-15

2-14

Step-by-step explanation:

Combinations for different rows will be, 14 - 8, 12 - 9, 0 - 15, 2 - 14.

    Given in the question,

Let the number of chess games played = x

And number of Uno games played = y

Therefore, equation for this situation will be,

2x + 4y = 60

For the 1st row given in the table,

If y = 8,

2x + 4(8) = 60

2x = 28

x = 14

For the 2nd row of the table,

If x = 12,

2(12) + 4y = 60

4y = 36

y = 9

For 3rd row of the table,

If y = 15,

2x + 4(15) = 60

x = 0

For 4th row of the table,

If x = 2,

2(2) + 4y = 60

4y = 56

y = 14

    Therefore, combinations for different rows will be, 14 - 8, 12 - 9, 0 - 15, 2 - 14.

Answer:

The radius is 4.5, while the area is equaled to 63.585

Step-by-step explanation:

Formula of circumference: radius times 2 times pie (3.14)

Formula of Area of Circle: radius squared times pie (3.14)

Divide 28.26 by 2 and by pie (3.14) to get the radius. You should get 4.5.

Square 4.5 (the radius), which should equal to 20.25. Then, multiply it by pie (3.14), which is equaled to 63.585. This is the area of the circle.

Answer:

There are 42 red colour socks and 44 green color socks

Step-by-step explanation:

Let there are r red socks and g green socks.

ATQ,

He has three times times as many red socks subtracted from four times as many green socks which he believes is 50 socks.

4g-3r=50 ....(1)

Half the number of green socks plus one-third of the number of red socks is 36.

[tex]\dfrac{g}{2}+\dfrac{r}{3}=36\\\\3g+2r=216\ .....(2)[/tex]

Multiply equation (1) by 2 and equation (2) by 3.

8g-6r = 100 ....(3)

9g +6r = 648 ....(4)

Add equation (3) and (4)

8g-6r + 9g +6r = 100+648

17g = 748

g = 44

Put the value of g in equation (1).

4(44)-3r=50

176-3r = 50

176-50 = 3r

r = 42

Hence, there are 42 red colour socks and 44 green color socks.

Answer:

Step-by-step explanation:

The coordinates of N so that line segment MN is 1/5 of line segment MP are (1, 14).

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).

From the image, we have the following:

Point M = (x₁, y₁) = (-1, 3)

Point P = (x₂, y₂) = (9, -22)

MN/MP = 1/5

Moving along line segment MP from M to P, the value of x increases by 10 (from -1 to 9) and y decreases by 25 (from 3 to -22). Thus, the x-coordinate and y-coordinate of N are given by:

x-coordinate of N = -1 + 1/5(10) = -1 + 2 = 1.

y-coordinate of N = 9 + 1/5(25) = 9 + 5 = 14

In conclusion, the coordinates of N so that line segment MN is 1/5 of line segment MP are (1, 14).

Answer:

Step-by-step explanation:

It is saying that both equations equal each other, as they both equal f(x). So we just move each of the factors to equal each other. Like 3x+5=11. There you just subtract the 5 from both sides to get 3x=6, and then divide both sides by 3 to get x=2.

Answer:

x=2

Step-by-step explanation:

f(x)=3x+5

11=3x+5

11-5=3x

6=3x

x=6

Step-by-step explanation:

Slope of horizontal line is zero (0)

m = 0

By point slope form of a line.

Answer:

x = 19

m<R = 17°

Step-by-step explanation:

PQR is a triangle and the sum of interior angles in a triangle is equal to 180°

m<P + m<Q + m<R = 180°

4x - 14 + 5x + 6 + x - 2 = 180° add like terms

10x - 10 = 180 add 10 from both sides

10x = 190 divide both sides by 10

x = 19

angle R is x - 2 so if we replace x with the value we found

m<R = 19 - 2 = 17°

Answer: B & D

Step-by-step explanation:

Answer:

B and D

Step-by-step explanation:

finding the cost is basically just taking the initial cost of the cereal and adding it to the percent times the initial cost.

D works because 100% of the initial cost of the cereal is still the initial cost of the cereal, so just add 15% to that 100%, and that is represented by 1.15 in decimal form.

(8-2) / (12-3)

6/9 simplified to 2/3

Answer:

A

Step-by-step explanation:

y = (1/4)x - 7

slope = 1/4

So, the slope of the perpendicular line  = -1/m = -1 ÷ (1/4)

                                                                 = -1 * (4/1) = -4

y - y1 = m(x -x1)

y - [-6] = -4(x - [-2])

Step-by-step explanation:

To find 20% of 50, multiply .20 x 50

.2 × 50 = 10

Answer:

10 pages

Step-by-step explanation:

20% of 50 pages

One way is converting 20% to a decimal 0.2

0.2 x 50 = 10 pages.

Hence , the poster will lie flat in the box as the area of box is much greater than the area of poster .

It is given that area of square framed poster = 9 sq. feet and volume of cube shaped box = 30 cubic feet.

Using volume formula , we get

      a³ =  12

      a = ∛12

      a = 2.28 feet

Putting a = 2√3 in equation (1) , we get area of cube

    6 (2.28)² = 6 × 5.19

                   = 31.19 square feet

Since the cube box is giant enough in order that the poster can lie flat within the box.

The probability that a perfect square is chosen is 0.08;

P represents the likelihood of selecting the number 'n' such that n>50. There are exactly 7 perfect squares less than 50. Therefore, there is a 7/50 chance of having a perfect square that is less than or equal to 50.

The likelihood of selecting the number "n" such that n>50 is also given as 3p. From 50 to 100, there are precisely 3 perfect squares. Therefore, there is a 3/50 chance of having a perfect square that is higher than 50 and less than or equal to 100.

The chance of selecting any number between "1" and "100" is p+3p=4p.

The probability that the chosen number is a perfect square and less than or equal to 50 is p × 7/50;

The odds that the selected number is larger than 50 but not higher than 100 and a perfect square are 3p × 3/50;

Consequently, the likelihood that any selected number is a perfect square is (p×7/50+3p×3/50)÷4p

If we simplify, we have 0.08.

Answer:

x = 2

Step-by-step explanation:

x/6 + 1 = 2x - 8/3 (first you want to multiply by 6 on both sides to get rid of x/6)

x + 6 = 12x - 16 (add 16 on both sides)

x + 22 = 12x (subtract x on both sides)

22 = 11x (divide by 11 on both sides)

2 = x
