Answer:

see explanation

Step-by-step explanation:

given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides , that is

22 - 18 < x < 22 + 18

4 < x < 40

3rd side can be any value from 5 to 39

Hailey and Kacie are selling candles to raise money. • Hailey is selling candles for $4 each and has already raised $160. • Kaci

marysya [2.9K]

Answer:

The number of candles each girl needs to sell so that the total amount raised is the same for both is

Hailey 70 candles

Kacie 40 candles

Step-by-step explanation:

Let

x------> the number of candles sold

y----> total amount raised

we know that

Hailey's equation

$y=4x+160$ -----> equation A

Please note that Hailey has already raised $160, so he has sold 40 candles.

Kacie's equation

$y=7x+70$ -----> equation B

Please note that Kacie has already raised $70, so he has sold 10 candles.

equate equation A and equation B solve for x

$4x+160=7x+70$

$7x-4x=160-70$

$3x=90$

$x=30\ candles$

The number of candles each girl needs to sell so that the total amount raised is the same for both is

Hailey

40+30=70 candles

Kacie

10+30=40 candles

PLEASE ANSWER ASAP

It is known
$\dfrac{\pi}{6} =30^{\circ}$ and
$\cos \dfrac{\pi}{6}= \dfrac{ \sqrt{3} }{2}$ (if you want to determine cosine of 30° you should draw the perpendicular line to the x-axis and find the point of intersection, the value of x-coordinate is the cosine of 30°).

The angle $\dfrac{5\pi}{6} =150^{\circ}$ and
$\cos \dfrac{5\pi}{6}=- \dfrac{ \sqrt{3} }{2}$ (see image).
The angle $\dfrac{7\pi}{6} =210^{\circ}$ and

$\cos \dfrac{7\pi}{6}=- \dfrac{ \sqrt{3} }{2}$ (see image).

Mike and Menna were instructed to graph the function y = 12 x + 1. Their graphs are shown.

KATRIN_1 [288]

Answer:

The function is y = 2x + 1.

And mike graphed the function correctly.

Menna took the point where the function touches x-axis incorrectly.

Instead of (-1/2,0), Menna took it as (-2,0)

Step-by-step explanation:

The equation y = mx +c indicates a straight line whose slope is m

And y-intercept is c.

y-intercept is nothing but the distance between origin and point where the graph crosses the y-axis (0,c).

Now, this graph crosses x-axis when y = 0.

⇒ mx + c = 0; ⇒ x = $\frac{-c}{m}$ .

Now, by comparing y = 2x + 1 with y = mx + c.

m=2 and c=1

⇒ the graph should crosses y-axis at (0,c) = (0,1)

And touch x-axis at ( $\frac{-c}{m}$ , 0) = ( $\frac{-1}{2}$ ,0)

⇒ mike graphed the function correctly.

Menna took the point where the function touches x-axis incorrectly.

Instead of (-1/2,0), Menna took it as (-2,0)
