1/8 is the fraction of the people who drank the soda, and 7/8 is the fraction of the soda that is left

Armando and Bianca are 290 feet apart when they start walking toward one another. Bianca walks twice as fast as

aivan3 [116]

9514 1404 393

Answer:

d = 290 -3x

Step-by-step explanation:

For each x feet that Armondo travels toward Bianca, Bianca travels 2x feet toward Armondo. The net effect is that the distance between them decreases by x+2x = 3x feet. The distance starts at 290 feet when x=0, so the distance can be described by ...

d = 290 -3x

Work out the size of one of the exterior angles

hodyreva [135]

<u>Given</u><u> </u><u>Information</u><u> </u><u>:</u><u>-</u>

⠀

A polygon with 10 sides ( Decagon )

⠀

<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>

⠀

The value of one of the exterior angles

⠀

<u>Formula</u><u> </u><u>Used</u><u> </u><u>:</u><u>-</u>

⠀

$\qquad \diamond \: \underline{ \boxed{ \pink{ \sf Exterior ~angle = \dfrac {360^\circ}{no. ~of~sides}}}} \: \star$

⠀

<u>Solution</u><u> </u><u>:</u><u>-</u>

⠀

Putting the given values, we get,

⠀

$\sf \dashrightarrow Exterior ~angle = \dfrac{360 ^\circ}{10} \: \: \\ \\ \\ \sf \dashrightarrow Exterior ~angle = \frac{36 \cancel{0}^\circ}{ \cancel{10}} \: \: \\ \\ \\ \sf \dashrightarrow Exterior ~angle = \underline{ \boxed{ \frak{ \red{36^\circ}}}} \: \star \\ \\$

Thus, the value of the exterior angles of a Decagon is 36°.

⠀

$\underline{ \rule{227pt}{2pt}} \\ \\$

4b.) Write an equation using point-slope form with a slope of 2.3 and goes

Yuri [45]

Answer:

$y+3.2=2.3(x-4.5)$

Step-by-step explanation:

So the point-slope formula looks like this: $y-y_1=m(x-x_1)$

$y_1$ = any y point on the line

$x_1$ = any x point on the line

$m$ = the slope

And hey, look, we're already given all that information!

So we can just plug those values into the equation:

$y+3.2=2.3(x-4.5)$

(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)

The equation of line AB is (y-3)=5(x-4) what is the slope of a line perpendicular to line AB

Softa [21]

Solving for y, we can start by expanding to get y-3=5x-20. Next, we can add 3 to both sides (to separate y), resulting in y=5x-17. To find the slope in the equation y=mx+b, you simply find what you multiply x by, which is 5 in this case. To find a perpendicular slope, you start by making the slope (5 in this case) negative. Next, we find the reciprocal of the number. Since -5 can be written as -5/1, the reciprocal and therefore perpendicular slope is -1/5
