Pretest 5. In a group of 250 students, 40 are seniors. What percentage of the group are seniors?

zvonat [6]

Answer:

$\%seniors = 16\%$

Step-by-step explanation:

Given

$Students = 250$

$Seniors = 40$

Required

Determine the percentage of seniors

This is calculated as thus;

$\%seniors = \frac{Seniors}{Students} * 100\%$

$\%seniors = \frac{40}{250} * 100\%$

$\%seniors = \frac{4000\%}{250}$

$\%seniors = 16\%$

The components of a vector are Ax = –10 units and Ay = 8 units. What angle does this vector make with the positive x axis? g

Mandarinka [93]

Answer:

This vector make an angle of 141° with the positive x axis

Step-by-step explanation:

Refer the attached figure

Components of vector :

$A_x=-10 \\A_y = 8$

We are supposed to find What angle does this vector make with the positive x axis

$tan \theta =\frac{A_y}{A_x}\\tan \theta =\frac{8}{-10}\\\theta =tan^{-1}(\frac{8}{-10})\\\theta =tan^{-1}(\frac{8}{-10})=-38.65^{\circ}$

Now ,

$\alpha = 180-38.65=141.35^{\circ}$

So, this vector make an angle of 141° with the positive x axis

Answer:

Perimeter = 21.58 units

Step-by-step explanation:

Perimeter of a polygon = Sum of measures of all sides of the polygon

Perimeter of the quadrilateral LEAP = PL + AE + EL + LP

= 4.47 + 4.47 + 6.32 + 6.32

= 21.58 units

[If the distances between two point are not given, use the formula to calculate the distance between two points $(x_1, y_1)$ and $(x_2,y_2)$

Distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ ]
