A surveyor is surveying a street. The surveyor is standing at point P looking down the street at a No Parking sign at point C and a Stop sign at point R. Given PC = 6x-5 meters, PR = 29 meters, CR = 7 meters, and point C is between P and R, what is xin meters?

Answers

Answer:

4.5 metres

Step-by-step explanation:

If  point C is between P and R, then PC+CR = PR.

Given PC = 6x-5

CR = 7 and PR = 29

Required

Find the value of x in metres

Substitute the given values into the formula;

6x-5+7 = 29

6x+2 = 29

subtract 2 from both sides

6x-2+2 = 29-2

6x = 27

Divide both sides by 6

6x/6 = 27/6

x = 27/6

x = 9/2

x = 4.5 metres

Hence the value of x in metres is 4.5metres

solve for x: x-10=-22

Answers

Answer:X would be -12

Step-by-step explanation: -12-10=-22

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that  h(x) = -3x – 5, and the value h(x) = -2. The value of x will be calculated as below:-

h(x) = -3x – 5,

-2=-3x -5

3=-3x

x=-1

Therefore, the value of x will be equal to -1 when the value of h(x) is -2.

Mary Jane is buying paper plates for her big going away party. The fancy plates come in packs of 8. She is inviting 41 guests. How many packs of plates should Mary Jane buy?

Since you cant buy .125 of a pack, Mary jane has to purchase 6 packs.

Answer:

6 packs

Step-by-step explanation:

41 guests     =  5.125 packs

8 plates

5 x 8 = 40 plates

6 x 8 = 48 plates

The area of a square is given by A=s2, where s is the length of each side of the square. If the area of a square room is 81 square meters, what is the length of one side of the room in meters?

Answers

Answer:  The length of one side is 9m.

Step-by-step explanation:

If area is 81 square meters, that means A = 81 m^2.

Since A = s^2, we can substitute s^2 for A.  Then

(s^2) = 81 m^2

Take the square root of both sides to solve for s:

(s^2)^(1/2) = (81 m^2)^(1/2)

s = 9 m

According to the American music industry, the length of a song is normally distributed with a mean of 240 seconds and standard deviation thirty seconds. Suppose a random sample of fifteen songs is selected from the morning program. what is the probability that the length of the song is between 225 and 260 seconds long?​

Answers

Answer:

96.89%

Step-by-step explanation:

Find the standard error:

s = σ/√n

s = 30 / √15

s = 7.75

Find the z-scores:

z = (x − μ) / s

z₁ = (225 − 240) / 7.75

z₁ = -1.94

z₂ = (260 − 240) / 7.75

z₂ = 2.58

Find the probability.

P(-1.94 < Z < 2.58) = P(Z<2.58) − P(Z<-1.94)

P(-1.94 < Z < 2.58) = 0.9951 − 0.0262

P(-1.94 < Z < 2.58) = 0.9689

AR:AB = 1/5 means that AR has length equal to 1/5 of the length of AB.

To find the x coordinate of R, you take 4/5 of the x coordinate of A plus 1/5 of the x coordinate of B:

4/5 * 1 + 1/5 * 4 = 8/5

You do the same for the y coordinate:

4/5 * (-1) + 1/5 * 4 = 0

So the point R has coordinates (8/5, 0).

slope: B. 2
- this is because slope= rise/run
- the rise is 2 and the run is 1
-2/1= 2

y-intercept: C. 1
- this is where the line crosses the y-axis (the vertical line in the center)

equation: C. 2x+1

- m is equal to the slope which we determined is 2
- b is equal to the y-intercept which we determined is 1
