The art club had an election to select a president. 57 members voted in the election and 19 did not vote. What percentage of the

laila [671]

Answer:

75% voted

Step-by-step explanation:

you add the 75 to 19 to figure out the total amount of people in the club.

75+19=76

Then you divide the people who voted which is 57 by the total amount of people in the club which is 76

57/76=0.75

then you move the decimal two places to the left and you get 75%

Tatiana is practicing shooting. The coordinates (in m) of the barrel of her gun and the target are (5, 3, 1) and (38, 41, 3). Wh

Answer:

$d=\sqrt{2,537}\ m$ or $d=50.37\ m$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points in three dimensions is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}+(z2-z1)^{2}}$

Let

$A(5,3,1)$ -----> coordinates of the barrel of her gun

$B(38,41,3)$ -----> coordinates of the target

substitute the values

$d=\sqrt{(41-3)^{2}+(38-5)^{2}+(3-1)^{2}}$

$d=\sqrt{(38)^{2}+(33)^{2}+(2)^{2}}$

$d=\sqrt{1,444+1,089+4}$

$d=\sqrt{2,537}\ m$

$d=50.37\ m$

The slope is 0, the equation is y=50
When the line is horizontal the slope is 0 and when the line is vertical the slope is undefined.

What is the perimeter of a square with side length (2x-3)?

Elis [28]

Answer:

Perimeter = 8x - 12

Step-by-step explanation:

The perimeter of a square is:

p = 4(side length)

on this case:

p = 4(2x-3)

p = 4*2x + 4*-3

p = 8x - 12

Please help me with this question

Hunter-Best [27]

Answer:

y = $\frac{1}{2}$ x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 2 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-2}$ = $\frac{1}{2}$

The line crosses the y- axis at (0, 1) ⇒ c = 1

y = $\frac{1}{2}$ x + 1 ← equation of line
