Answer:

Angle of elevation = 77.1°

Step-by-step explanation:

The formula to solve for angle if elevation is given below as:

tan θ = Opposite/ Adjacent

Where

Opposite = Height of the building = 653 ft

Adjacent = Distance from the building = 150 ft

θ = Angle of Elevation = ?

Hence:

tan θ = 653ft/150ft

θ = arc tan (653ft/150ft)

= 77.063069956°

Approximately to the nearest tenth = 77.1°

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:

(-1, 8)

x = -1   y = 8

Step-by-step explanation:

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)".

Answer:

There will be 20 914 rupees in the amount at the end of 3 years.

Step-by-step explanation:

The amount of rupes after t years in compound interest is given by:

[tex]A(t) = A(0)(1+r)^{t}[/tex]

In which A(0) is the initial amount and r is the interest rate, as a decimal.

Hiran invests 20 000 rupees in an account for 3 years at 1.5% per year compound interest.

This means that [tex]A(0) = 20000, r = 0.015[/tex]. So

[tex]A(t) = A(0)(1+r)^{t}[/tex]

[tex]A(t) = 20000(1+0.015)^{t}[/tex]

[tex]A(t) = 20000(1.015)^{t}[/tex]

Work out the total amount of money in the account at the end of 3 years.

This is A(3). So

[tex]A(3) = 20000(1.015)^{3} = 20913.6[/tex]

Rounding to the nearest rupee.

There will be 20 914 rupees in the amount at the end of 3 years.

Step-by-step explanation:

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:

Step-by-step explanation:

[tex]7 + x = t[/tex]

Move 7 to the right side.

Note : That when a number crosses an equality sign , the sign changes.

[tex]x = t - 7[/tex]

Answer:

x=t-7

Step-by-step explanation:

To make x the subject of the formula 7 + x = t

What we mean is that we want x to stand alone.

So if we want x to stand alone then we will subtract both sides by 7 to make the x stand alone.

-7+7+x=t-7

x = t - 7

So now the final answer becomes;

x = t - 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]

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.
