Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning.

andrey2020 [161]

Answer:

Hey! The answer is 25,4 centimeters.

Step-by-step explanation:

In a linear function you can use y=mx+n

So if x = hours and y= height.

You know that

$\left \{ {{27,8=11m +n} \atop {24,8=26m +n}} \right.$

So:

If you multiply (24,8=26m +n) x-1

It is: -24,8 = -26m -n

Adding up the other equation

-24,8 = -26m -n

27,8 = 11m + n

3 = -15m

m= -0,2

27,8 = 11 x 0,2 + n

27,8 = -2,2 + n

30 = n

This results that te linear function for this equation is:

y = -0,2x + 30

The answer is

y=23(-0,2) + 30

y=-4,6+30

y=25,4

What are the sizes of angles a, b, c and d?

Lilit [14]

Answer:

a = 26°

b = 48°

c = 26°

d = 106°

Step-by-step explanation:

$c + {154}^{o} = {180}^{o} \\ c = {180}^{o} - {154}^{o} \\ c = {26}^{o}$

a = c (Alternate angles)

$a = {26}^{o}$

$b = {48}^{o}$

Corresponding angles

(a + d) + b = 180° (Interior angles)

${26}^{o} + d + {48}^{o} = {180}^{o} \\ d + {74}^{o} = {180}^{o} \\ d = {180}^{o} - {74}^{o} \\ d = {106}^{o}$
