I want to find the value of x

Step-by-step explanation:

The area of a rectangle is 171 m²

Let l is the length and b is the width of the rectangle

It width is 10 m less than the length. So,

b = l-10 ...(1)

Area of a rectangle is given by :

[tex]A=l\times b\\\\171=l(l-10)\\\\l^2-10l=171\\\\l^2-10l-171=0\\\\l^2-19l+9l-171=0\\\\\text{taking common together}\\\\l(l-19)+9(l-19)=0\\\\(l-9)(l-19)=0[/tex]

or

l = 9 m or l = 19 m

If l = 9 m,

b = 9-10 = -1 m (can't be possible)

If l = 19 m

b = 19-10 = 9 m

So, the length an the breadth of the rectangle is 19 m and 9 m respectively.

Answer:

I am pretty sure it is when you have a sequence of numbers that you are subtracting or adding from by the same constant over and over

Step-by-step explanation:

an=a1+(n-1)d

d=common difference

an= the nth term in the sequence

a1 first term in the sequence. (Usually you can plug in 1, as the n, and work from there)

Answer: C , 0.29

Step-by-step explanation:

P(D) is the probability flirting of directly in person.

represents probability of flirting other than in person.

P(D)=0.710.

= 1 - 0.710.

= 0.29

Hence the value of Upper P left parenthesis Upper D overbar right parenthesis is 0.29.

Answer:

The width is 3 ft

The length is  12 ft

Step-by-step explanation:

Let w = width

l = 4w

A = l*w

Replace length with 4w

A = 4w*w

36 = 4 w^2

Divide each side by 4

36/4 = 4w^2/4

9 = w^2

Take the square root of each side

sqrt(9) = sqrt(w)

3 =w

The width is 3 ft

The length is 4*3 = 12 ft

Step-by-step explanation:

Answer:

Since there is one value of  y  for every value of  x  in  ( 1,−2) ,( 2,1),(3,6), (4,13 ) ,(5 ,22 ) , this relation is a function.

The relation is a function.

A relation is a function if it has only one y-value for each x-value. The relation (1,−2), (2,1), (3,6), (4,13), (5,22) is a function.

A relation is a function if it has only one y-value for each x-value.

The given relation is one comma minus two

two comma one

three comma six

four comma thirteen

five comma twenty two.

(1,−2), (2,1), (3,6), (4,13), (5,22)

In the ordered pairs (x, y) , there should not have same y value.

As we observe there are only one y values for x value.

Every domain element is have unique codomain element.

Hence the relation  (1,−2), (2,1), (3,6), (4,13), (5,22) is a function.

Step-by-step explanation:

Slope

All answers agree that the slope = - 3

y intercept

So far what you know is that the line is

y = -3x + b

The point shows that

5 = -3*2 + b                    Combine right

5 = -6 + b                        Add 6 to both sides

5 + 6 = -6+6 + b             Combine

11 = b

So the y intercept = 11

Answer: y = -3x + 11              D

took da quiz

Answer:

B

Step-by-step explanation:

Answer:

Let the parts be given as x,

180° = 3x + 1x + 4x (Because a straight angle = 180°)

=> 180° = 8x

=> 180 / 8 = x (By the law of transposition)

=> 22.5 = x

Therefore the three different angles are :

67.5° , 22.5° , 90° respectively

Check,

=> 67.5 + 22.5 + 90

=> 90 + 90

=> 180°

Answer:

2,000

Step-by-step explanation:

An easy way of solving problems like these is to count the number of zeros in the equation, temporarily remove them, solve the new problem, and then add all the zeros that you removed before. In this case:

100 x 20 = ?

1 x 2 = ?  | 000

2 | 000

2,000

Here's another example:

300 x 5000 = ?

300 x 5000 = ?

3 x 5 = ?  | 00000

15 | 00000

Answer:

37°

Step-by-step explanation:

We have been given the diagram of the triangle;

 To find the angle I;

 We need to apply one of the geometry laws,

The sum of adjacent internal angles of a triangle gives the external angle;

So;

      I + 115  = 152

   Solve for I;

      I  = 152 - 115 = 37°

Answer:

A. 0.22

B. 0.18

C. 0.25

D. 0.244

Step-by-step explanation:

S = {51 to 100} = 50

The sample space S contains values from 51 to 100 which is a total of 50 different values.

A.

Probability of A (lies between the values of 90 to 100 = 11).

11/50 = 0.22

B.

For a student to fail the course, his course has to be less than 60 = from 51 to 59. A total of 9 values.

9/50 = 0.18

C.

For student to get c, (70 to 79) a total of 10 values: 10/50 = 0.20

P(student did not get C) = 1-0.20 = 0.80

To get B, ( 80 to 89)

10/50 = 0.20

Probability that a student who is known not to have a c grade has a b grade = 0.20/0.80 = 0.25

D.

Probability of passing lies between 60 to 100 = 41 scores

41/50 = 0.82

Probability of student who passed having a B = 0.20/0.82 = 0.244
