Answer:

$Rx+Py=RP$

Step-by-step explanation:

The points on the straight line are (P, 0) and (0, R).

The slope would be

$m=\frac{R-0}{0-P}=-\frac{R}{P}$

And $b=R$ , because the y-intercept is at (0, R).

So, the equation of this line would be

$y=-\frac{R}{P} x+R$

Where we multiply the equation by $P$

$Py=-Rx+RP$

Therefore, the equation that represents this line is

$Rx+Py=RP$

<h2>So, the right answer is B.</h2>

One angle of an isosceles triangle measures 110°. Which other angles could be in that isosceles triangle? Choose all that apply.

andre [41]

Answer:

Therefore the correct option is 2. 35 degree.

$\angle ABC=\angle ACB=35\°$

Step-by-step explanation:

Consider an Isosceles Triangle, Δ ABC where,

∠BAC = 110°

TO Find:

∠ ABC = ∠ACB = ?

Solution:

For an Isosceles Triangle

Base Angles are equal

∴ $\angle ABC=\angle ACB=x\ (say)$

Now,

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

$\angle A+\angle B+\angle C=180\\\\110+x+x=180\\\therefore 2x=180-110=70\\\therefore x=\dfrac{70}{2}=35\°$

Therefore,

$\angle ABC=\angle ACB=35\°$

Find the distance between the points (-7.2, -9.3) and (-7.2, -1.1)

AlexFokin [52]

Answer:

8.2

Step-by-step explanation:

-7.2 to -7.2 is 0

-9.3 to -1.1 is 8.2

Pythagorean theorem is a^2+b^2=c^2

0^2=0

8.2^2=67.24

0+67.24=0

√67.24=8.2

The distance between the to points is 8.2

Kendall is making greeting cards, which she will sell by the box at an arts fair. She paid $40

natta225 [31]

Answer:

Step-by-step explanation:

40 dollars due up front

10 dollars made per sale

5 dollars lost per creation

Realistically speaking she is only making a $5 profit per box she sells;

<em>$5 used up for material cost, $10 made from sales </em><em>-5+10= 5</em>

To pay the $40 dollar for the booth she would need to make 9 sales with her current profit
