Which is larger 4m or 380 cm

2 answers:

6 0

Well to first find this out, we need to set these up to a whole meter.

1 Centimeter = 1/100 meter (hence the prefix "centi").

4 meters = 4/1 meter.

It would take 400 centimeters to get 4 meters, as 100 centimeters = 1 meter.
Given that information, 380 centimeters is less than 400, so it is less than 4 meters.

4m is larger than 380cm.

I hope this helps!

380 cm is only 3.8 meters.....so 4 meters is larger..............................

Find the distance between the lines with the given equations.<br> 3x+y = 1<br> y+6=-3x

den301095 [7]

Answer:

2.21 units

--------------------------------

Given lines:

3x + y = 1 and y + 6 = - 3x

Convert both equations to slope-intercept form of y = mx + b:

3x + y = 1 ⇒ y = - 3x + 1
y + 6 = - 3x ⇒ y = - 3x - 6

Slopes are same, so these are parallel lines, and the distance between parallel lines is:

$d=\cfrac{|b_1-b_2|}{\sqrt{1+m^2} }$ , where b₁, b₂ - y-intercepts, m- slope

Substitute and calculate:

$d=\cfrac{|1+6|}{\sqrt{1+(-3)^2} }=\cfrac{7}{\sqrt{10} } =2.21$

Find the slope of the line that passes through (10, 9) and (3, 18).

MakcuM [25]

Answer: Slope of the line is -9/7

Step-by-step explanation:

Given :

Points : (10,9) and (3,18)

Now slope of line when two points are given

m= $\frac{y2-y1}{x2-x1}$

Slope = $\frac{18-9}{3-10}$

m= $\frac{9}{-7}$

m= $\frac{-9}{7}$

This is an improper fraction since numerator is greater than the denominator

Hence slope of the line is -9/7

Answer:

a) $y=\frac{28}{75}(x-1900)+47.3$

b) 86.5 years

Step-by-step explanation:

All values are rounded to 2 decimal places

a) We can find line by using y =mx+b

$y=mx+b\\m=\frac{y^{2}-y^{1} }{x^{2}-x^{1}}\\m=\frac{69.7-47.3}{1960-1900} \\m=\frac{22.4}{60} \\m=\frac{28}{75}\\c=y-intercept\\y-intercept=47.3\\y=\frac{28}{75} (x-1900)+47.3$

Therefore the line of best fit is $y=\frac{28}{75}(x-1900)+47.3\\$

b) We can do this by using the formula of the best fit line to estimate the life expectancy of someone born in 2005

$y=\frac{28}{75}(x-1900)+47.3\\y=\frac{28}{75}(2005-1900)+47.3\\y=\frac{28}{75}\times105+47.3\\y=86.5$

Therefore the estimated life expectancy of someone born in 2005 is 86.5 years

PS. Please give brainliest answer this was a lot of working out
