The solution is 170°, is the measure of the remaining angle.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

here, we have,

given that,

The measures of 5 of the interior angles of a hexagon are: 160°, 90°, 60°, 160°, and 80°.

so, we have,

Sum of all the six interior angles of a hexagon is 720°

now, we get,

The sum of 5 interior angles is = 160°+ 90°+ 60°+ 160°+ 80° degrees

                                                  = 550

The missing 6th angle is =  720° - 550degrees

                                         =170

So the remaining angle of hexagon is 170 degrees.

Therefore, the answer is 170°.

Answer:

Step-by-step explanation:hj

Using linear function concepts, it is found that these lines intersect at x = 8.

The equation of a line is given by:

[tex]y = mx + b[/tex]

In which:

Line perpendicular to y = 2x - 3.

Multiplication of the slopes is -1, thus:

[tex]2m = -1[/tex]

[tex]m = -\frac{1}{2}[/tex]

y-intercept of 17 means that b = 17, thus, the equation of the line is:

[tex]y_p = -\frac{1}{2}x + 17[/tex]

They intersect at the value of x for which:

[tex]y = y_p[/tex]

Then

[tex]2x - 3 = -\frac{1}{2}x + 17[/tex]

[tex]2x + \frac{1}{2}x = 20[/tex]

[tex]\frac{5x}{2} = 20[/tex]

[tex]5x = 40[/tex]

[tex]x = \frac{40}{5}[/tex]

[tex]x = 8[/tex]

Answer:

[tex]T = 600[/tex]

Step-by-step explanation:

Represent the table with T, couch with C an umbrella with U

We have the following:

[tex]2C + U + T = 1875[/tex]

[tex]C + T = 1075[/tex]

[tex]2C + U = 1275[/tex]

Required

Determine the cost of a table

Make T [tex]the\ subject\[/tex] [tex]in\ the[/tex] first equation

[tex]T = 1875 - (2C + U)[/tex]

In the third equation, we have that: [tex]2C + U = 1275[/tex]

By substituting 1275 for 2C + U

[tex]T = 1875 - (2C + U)[/tex] becomes

[tex]T = 1875 - 1275[/tex]

[tex]T = 600[/tex]

Hence, a table costs $600

Step-by-step explanation:

Answer:

4b+18

Step-by-step explanation:

Expand the left side using the angle sum identity for sine:

sin(x + π/2) = sin(x) cos(π/2) + cos(x) sin(π/2)

cos(π/2) = 0 and sin(π/2) = 1, so the right side reduces to

sin(x + π/2) = cos(x)

Step-by-step explanation:

Number of hardcover books 18, + number of paperback book add up to make a total of 41, which makes the equation, p+18=41, to solve this, you want to have p by itself, simply subtract 18 from both sides, and you get p = 23.

Answer:

1.56

Step-by-step explanation:

Given that :

Average height (μ) = 70 in

10% are taller than 72 in ; the standard deviation Given a normal distribution :

P(x > Z) = 0.10

Using a Z probability calculator, the Z value corresponding to P(x > Z) = 0.10 is 1.282

Z = 1.282

Using the Z relation:

Z = (x - μ) / σ

σ = standard deviation x = 72

1.282 = (72 - 70) / σ

1.282σ = 2

σ = 2 / 1.282

σ = 1.5600624

σ = 1.56

The correct graph to the parent function after the transformation is shown in the picture.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a parent function:

y = |x|

Applying first transformation:

Multiply by 1/3 the graph of the function will stretch

[tex]\rm y = \dfrac{1}{3} |x|[/tex]

Second transformation:

Add 1 to the function, the graph will shift upside by 1 units.

[tex]\rm y = \dfrac{1}{3} |x|+1[/tex]

Thus, the correct graph to the parent function after the transformation is shown in the picture.

Step-by-step explanation:

all are more then zero

Answer:

a) there are 7,854,000 number of ways the random selections can be arranged

b) the required probability is 0.0445

Step-by-step explanation:

Given that;

you have 12 pair of long pants, 6 pair of short pant and 17 t-shirt which in total;

Total = 12 + 6 + 17 = 35

a) number of ways a random selection of 9 pair of long pants, 4 pair of short pants and 13 t-shirts can be arranged;

⇒ [ 12   ×    [ 6     ×    [ 17

     9 ]          4 ]           13 ]

= (12! / (9! 3!)) (6! / (4! 2!)) (17! / (13! 4!))

= (220) (15) (2380)

= 7,854,000

Therefore there are 7,854,000 number of ways the random selections can be arranged

b)

Number of ways of selecting 25 item from 35 items;

⇒ [ 35        

    25 ]

=

(35! / (25! 10!) = 183.579,396

now number of ways to select 10 pair of long pants, 3 pairs of short pantts and 12 t-shirt;

⇒ [ 12   ×    [ 6     ×    [ 17

     10 ]         3 ]           12 ]

= (12! / (10! 2!)) (6! / (3! 3!)) (17! / (12! 5!))

= (66) (20) (6188)

= 8,168,160

So, Required probability = 8,168,160 / 183,579,396

= 0.0445

So the required probability is 0.0445

[tex]c + 2c + c - 5c + 1 \\ = - c + 1[/tex]

The condition that must be true about the probabilities is P(A and B) = xy

The probabilities of the events A and B are given as:

P(A) = x

P(B) = y

Given that events A and B are independent events, then we have the following equation

P(A and B) = P(A) * P(B)

The equation becomes

P(A and B) = x * y

P(A and B) = xy

Hence, the condition that must be true is P(A and B) = xy
