Step-by-step explanation:

Since Angle DAB = 90°,

DB is the diameter of the circle.

Therefore m(Arc DA) + m(Arc AB) = 180°.

=> m(Arc AB) = 180° - 47° = 133°.

Answer:

1.71

Step-by-step explanation:

got it right on my test

The required value of x for the given equation is about 1.71.

Important information:

Divide both sides by 10.

[tex](1.5)^{3x}=\dfrac{80}{10}[/tex]

[tex](1.5)^{3x}=8[/tex]

Taking log on both sides, we get

[tex]\log (1.5)^{3x}=\log 2^3[/tex]

[tex]3x\log (1.5)=3\log 2[/tex]

Divide both sides by 3log(1.5).

[tex]x=\dfrac{3\log 2}{3\log 1.5}[/tex]

[tex]x=\dfrac{\log 2}{\log 1.5}[/tex]

[tex]x\approx 1.71[/tex]

Therefore, the required value of x for the given equation is about 1.71.

Answer:

26

Step-by-step explanation:

h=21+5

h=26

The value of h will be 26, when p =7.

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero.

The method  in which, the value of one variable from one equation is substituted in the other equation. So that, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved. This method is called substitution method.

According to the given question we have

A linear equation in two variable

h = 3p + 5

So, the value of h when p = 7

Substitute, p = 7  in h = 3p + 5

⇒ h = (3 × 7) + 5

⇒ h = 21 + 5

⇒ h = 26

Hence, the value of h will be 26, when p =7.

1x+7

Answer:

1x + 7

Step-by-step explanation:

hey there!first, we put the x numbers on one and the numbers without the x on one side that will look like 7x-6x + 5 + 2 then we slove them that will look like 1x +7 now we add them but we cant not add them because one number is with x and the other number is not with x. if we can not slove we can write them as 1x + 7

Answer:

Jill had $136.50 before buying the book.

Step-by-step explanation:

Let x be the total amount that Jill had

Then 12% of x is 0.12x

Jill was left with $120.12 after buying the book

Subtracting the cost of book from the total amount will given us the remaining amount.

Which means

[tex]x - 0.12x = 120.12\\0.88x = 120.12\\x = \frac{120.12}{0.88} \\x = 136.50[/tex]

Hence,

Jill had $136.50 before buying the book.

The probability of a license plate meeting all the given criteria is approximately 0.0000126, or  [tex]1.26 x 10^{-5[/tex].

Given that: A city issues 3-digit license plates and digits are 0 to 9.

Having all different digits:

To calculate this probability, use the same approach as before:

Number of favourable outcomes = 10 × 9 × 8

Total number of possible outcomes = 10 × 10 × 10

Probability = (Number of favourable outcomes) / (Total number of possible outcomes)

Probability = (10 × 9 × 8) / (10 × 10 × 10)

Probability = 720 / 1000

Probability = 0.72                                        (*)

Having at least one even digit:

So, the license plate must have all odd digits (1, 3, 5, 7, or 9).

Number of favourable outcomes = 5 × 5 × 5

Total number of possible outcomes = 10 × 10 × 10

Probability = (5 × 5 × 5) / (10 × 10 × 10)

Probability = 125 / 1000

Probability = 0.125                                      (1)

Now, the probability of having at least one even digit is the complement of the above probability:

Probability of having at least one even digit = 1 - 0.125

Probability = 0.875                                  (2)

Having the digits in ascending or descending order:

Ascending: 012, 123, 234, 345, 456, 567, 678, 789

Descending: 987, 876, 765, 654, 543, 432, 321, 210

Total favourable outcomes = 8 + 8

Total favourable outcomes = 16

Probability = 16 / 1000

Probability = 0.016                                 (3)

Having a specific digit in a specific position:

Let's say want the digit 7 to be in the first position.

Number of favourable outcomes = 1

Total number of possible outcomes = 10 × 10

Probability = 1 / 100

Probability = 0.01                                              (4)

Now, to find the probability of all criteria being met simultaneously, multiply the individual probabilities:

Probability of meeting all criteria = Probability (1) × Probability (2) × Probability (3) × Probability (4)× Probability (*)

Probability of meeting all criteria = 0.125 × 0.875 × 0.016 × 0.01 × 0.72

Probability ≈ 0.0000126

Hence, the probability of a license plate meeting all the given criteria is approximately 0.0000126.

Answer: (3,4)

(X,Y) (X1- Y1)+ (X2- Y2)

The coordinate of point Q is (3,4).

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

Coordinate point Q can be given by interception formula that state

Coordinate a point with intercept m: n  and bounded by coordinate (x₁, y₁) and (x₂, y₂).

x = [m(x₂) + n(x₁)]/(m + n)

And,

y = [m(y₂) + n(y₁)]/(m + n)

So,

x = [5(5) + 2(-2)]/(5 + 2)

x = 3

Similarly

y = [5(8) + 2(-6)]/(5 + 2)

y = 4

Hence "The coordinate of point Q is (3,4)".
