Sam's new room is square, and each side measures 15 feet. What is the
area of the room?

To find the missing angle, we need to find x.

[tex]3x + 2x - 10 = 180\\\\5x - 10 = 180\\\\5x = 190\\\\x = 38[/tex]

Now, we plug in what we got for x into 3x.

[tex]3(38)\\\\114[/tex]

The value of 3x is 114.

Answer:

M=54

Step-by-step explanation:

If you are trying to find the value of M, you add 5 to both sides

M-5+5=49+5

this way the M is all by itself on the left side of the equal sign because -5+5=0

when we combine the like terms we get

M+0=54

therefore M=54

Also 54-5=49

Answer:

2.57 - 1.75 = 0.82

Step-by-step explanation:

Let us assume that we need to find the value of 2.57 - 1.75 i.e. we need to subtract 1.75 from 2.57. It can be done as follows :

The first number is 2.57 and other no is 1.75.

In 2.57, 2 is in ones place, 5 is in tenths place and 7 is in hundredths place.

In 1.75, 1 is in ones place, 7 is in tenths place and 5 is in hundredths place.

Subraction :

  2.57

-  1.75

= 0.82

Hence, the value of 2.57 - 1.75 is 0.82

Answer:

Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).

Step-by-step explanation:

Answer:

The slope of the line is -2.

Step-by-step explanation:

Because the line is going down from left to right it is considered a negative slope. The rise is -2 and the run is 3, so the slope of the line in integer form is -2.

But, if it was in fraction form the slope would be -2/3.

Answer:

x= 1/5 or -2

Step-by-step explanation:

5x² +11x +2= 0

(Divide through by the coefficient of x²)

5x²/5 + 11x/5 + 2/5 = 0/5

x² + 11x/5 + 2/5 = 0

(take the constant to the other side)

x² + 11x/5 = -2/5

(Add 1/2 of the coefficisint of x all square to both sides)

x² + x + (11/5 × 1/2)² = -2/5 + (11/5 × 1/2)²

x² + x + (11/10)² = -2/5 + (11/10)²

x² + x + (11/10)² = -2/5 + 121/100

(eliminate x )

x² + (11/10)² = (20(-2) + 121 ) ÷ 100

(x + 11/10 )² = (-40 + 121) ÷ 100

(x + 11/10 )² = 81/100

(square both sides)

x + 11/ 10 =√(81/100)

x + 11/10 = 9/10

x = -11/10 +or- 9/10

x = -11/10 + 9/10 or -11/10 - 9/10

x = (-11 + 9) ÷ 10 or (-11-9) ÷ 10

x = -2/ 10 or -20/10

x = -1/5 or -2

Step-by-step explanation:

sin29

k

​

=

sin124

18

​

Plug in. Opposite sides go together.

k=\frac{18\sin 29}{\sin 124} \approx 10.526 \approx 10.5

k=

sin124

18sin29

​

≈10.526≈10.5

The required length of k is 10.5 inches for the given triangle.

The sine rule defines the side length ratios of triangles to their opposing angles. This proportion is true for all three sides and opposing angles.

a/sinA = b/sinB = c/sinC

The triangle is given in the question, as follows:

In ΔKLM, m = 18 inches, ∠M=124° and ∠K=29°.

We have to determine the length of k.

As per the sine rule, the required solution would be as:

m/sin∠M = k/sin∠K

Substitute the known values and we get

18/sin 124° = k/sin 29°

k = (18/sin 124°) × sin 29°

k ≈ 10.5

Thus, the length of k is 10.5 inches.

The value of x in the equation is 4.

An Algebraic expression shows the expression of variables with numbers. The purpose of an algebraic expression is to determine the unknown variable represented by an unknown letter.

From the given information:

2(6x + 4) - 6 + 2x = 3(4x + 3) + 1

Open brackets

12x + 8 - 6 + 2x = 12x + 9 + 1

Collect like terms

12x + 2x - 12x = -8 + 6+9 + 1

14x - 12x = -8 + 16

2x = 8

x = 8/2

Answer:

91%

Step-by-step explanation:

we can use combinations:

Total probabilities = 12! / (4!8!) = 479,001,600 / 967,680 = 495

Probability of no defective unit = ₁₀C₄ = 10!/4!6! = 3,628,800 / 17,280 = 210

Probability of one defective unit = ₁₀C₃ · ₂C₁ = 10!/3!7! · 2!/1! = 120 · 2 = 240

Probability of no more than one defective unit = (210 + 240) / 495 = 450 / 495 = 91%

Complete question :

Ankit makes 74% of the free throws he takes in his basketball league. If he is fouled on a three-point shot and gets three free throws, what is the approximate probability he will make all three shots?

Answer:

0.405224

Step-by-step explanation:

Given that:

p(success) = p = 74% = 0.74

If given 3 free throws ; probability of making all 3

Using binomial fórmula :

p = 0.74 ;

1 - p = 0.26

P( x = x) = nCx * p^x * (1 - p)^(n-x)

P(x = 3) = 3C3 * 0.74^3 * 0.26^0

P(x = 3) = 1 * 0.405224 * 1

P(x = 3) = 0.405224

The third term of the sequence is 17

The given can be interpreted as thus:

Given the following parameters

First-term = 15

Sixth term = 20

Assuming the sequence is an arithmetic sequence, the nth term of an arithmetic sequence is expressed as;

Tn = a + (n-1)d

a is the first term

d is the common difference

a = 15

T6 = a+ 5d

20 = 15 + 5d

20-15 = 5d

5 = 5d

d = 5/5

d = 1

Get the third term:

T3 = a+ 2d

T3 = 15 + 2(1)

T3 = 17

Hence the third term of the sequence is 17
