Suppose you walk 18.5 m straight east and then 22.5 m straight north. How far are you from your starting point in m)? וח What is the compass direction of a line connecting your starting point to you

Answers

Answer 1
Answer:

Final answer:

The distance from the starting point is approximately 29.14 meters and the compass direction of the line connecting the starting point to the end point is approximately 50.03° east of north.

Explanation:

To find the distance from the starting point, we can use the Pythagorean theorem which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the two legs. In this case, the two legs of the triangle represent the distances walked in the east and north directions. So, the distance from the starting point is:




Distance = sqrt((18.5)^2 + (22.5)^2)


Distance = sqrt(342.25 + 506.25)


Distance = sqrt(848.50)


Distance ≈ 29.14 meters



To determine the compass direction of the line connecting the starting point to the end point, we can use trigonometry. We can find the angle of this line with respect to the east direction using the tangent function:




Angle = arctan(22.5/18.5)


Angle ≈ 50.03°



Therefore, the distance from the starting point is approximately 29.14 meters and the compass direction of the line connecting the starting point to the end point is approximately 50.03° east of north.

In a housing project there are 350 households in which English is spoken, 50 in which Spanish is spoken, and 100 in which the language is other than English or Spanish. If a psychologist approaches a house at random to conduct an interview, the chance that the language in that household will NOT be English?a- .002b- .14c- .3d- .43

Answers

Answer:   C. 0.3

Step-by-step explanation:

Given : Number of English speaking households =350

Number of Spanish speaking households =50     (1)

Number of households in which the language is other than English or Spanish=100      (2)

Total households participates in this survey =350+50+100=500

No. of households not speak English =100+50=150    (Add (1) and (2))

If a psychologist approaches a house at random to conduct an interview, the chance that the language in that household will NOT be English will be :_

\frac{\text{No. of households not speak English}}{\text{Total households}}\n\n=(150)/(500)\n\n=(3)/(10)=0.3

Hence, the correct option is option (c).

In not so complicated math problems, a rough estimate or mentally-calculated estimate, sometimes referred to as a "ballpark estimate," helps to predict the numerical range the final answer should fall within. For example, if the given problem is to determine the sum of 23 plus 76, it can be estimated that the final and precise answer will be somewhere close to 100 because the known calculation 25 plus 75 equals 100 is close to the given problem 23 plus 76.

Answer:

x> -1/2

Step-by-step explanation:

Answer:

The answer is x > - 1/2

Step-by-step explanation:

Solve x2 + 4x − 12 = 0.A: x = 2, x = −6
B: x = −2, x = −6
C: x = 3, x = −4
D: x = −3, x = 4

Answers

x^2 + 4x - 12 = 0
(x + 6)(x - 2) = 0

x + 6 = 0          x - 2 = 0
x = -6               x = 2

Answer A: x = 2; x = -6

Which is the solution set of the inequality 15y-9 < 36y>9/5

y<9/5

y < 3

y>3

Answers

In solving for the solution set of the inequality 15y - 9 < 36, much like any other algebraic equation, the first step should be to isolate y. This is done as follows:

15y - 9 < 36

Adding 9 to both sides of the equation:
15y - 9 + 9 
< 36 + 9
15y 
< 45

Dividing both sides by 15 to isolate y:
15y/15 
< 45/15
< 3

Therefore the answer is the third choice y 
< 3.

y<3
