Answer:

Elena is 142 centimeters tall.

Elena is 1.42 meters tall.

Step-by-step explanation:

1. Calculate the height of Elena in centimeters:

$56inches*\frac{254centimeters}{100inches}=142centimeters$

Elena is 142 centimeters tall.

2. Calculate the height of Elena in meters:

As 100centimeters = 1 meter, we have the following:

$142.24centimeters*\frac{1meter}{100centimeters}=1.42meters$

Elena is 1.42 meters tall.

Answer:

142.24cm

Step-by-step explanation:

If 100 inches = 254cm then if you do 254/100 you will get how many cm are in an inch. 254/100 = 2.54

This means there are 2.54 cm in an inch. Multiply 2.54cm by 56 inches and you get how many cm are in 56 inches which is 142.24cm. This means Elena is 142.24 cm tall.

The points (-6, r)<br> and<br> (6,3) lie on a line with slope 3/4. Find the missing coordinate r.

NeTakaya

Answer:

r = -6

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept.

Slope 3/4

This means that $m = \frac{3}{4}$ , and thus:

$y = \frac{3}{4}x + b$

(6,3)

This means that when $x = 6, y = 3$ . We use this to find b. So

$y = \frac{3}{4}x + b$

$3 = \frac{3}{4}(6) + b$

$b = 3 - \frac{18}{4} = \frac{12}{4} - \frac{18}{4} = -\frac{6}{4}$

$y = \frac{3}{4}x - \frac{6}{4} = \frac{3x - 6}{4}$

(-6, r)

r is y when $x = -6$ . So

$y = \frac{3(-6) - 6}{4} = -6$

So r = -6.

What is the slope of Y=.2x-7

sveticcg [70]

What is the slope of Y= 2x-7

$\text { The slope of } y=2 x-7 \text { is } 2$

<u>Explanation</u>:

$\text { The given line is } y=2 x-7$

$\text { The given line is in the form of } y=m x+b$

$\text { That is } y=2 x+(-7)$

Where

m is slope of the equation

Slope: The slope of a line is also called as gradient of line it is denoted by a letter m.

$\text { b is the } y-\text {intercept.}$

$\text { Hence the value of slope is } m=2$

$y-\text { Intercept is } b=-7$
