Answer:

The correct option is 3.

Step-by-step explanation:

If a line passes through to points (x_1,y_1) and (y_1,y_2), then the slope of line is

m=\frac{y_2-y_1}{x_2-x_1}

Given points are (4,-7) and (6,3).

The slope between given points is

m=\frac{3-(-7)}{6-4}

m=\frac{3+7}{2}

On further simplification we get

m=\frac{10}{2}

m=5

Therefore the correct option is 3.

alukav5142 [94]

Answer:

10 more girls

Step-by-step explanation:

So here 2/3 of 24 ran for first race

Then it gives us that 16 girls ran for first race.

Next, 1/4 of 24 ran for second race

That is 6 girls

The remaining girls ran for the third race,

24 - 22

2 girls

16 - 6 = 10

So for first race 10 more girls ran

Write the equation of the line that passes through the point ( -6 , 2 ) and is parallel to the line y = 1/2x + 4.
SashulF [63]
Parallel lines need the same slope, and for y = 1/2x + 4, it is 1/2.

Let's solve for b.

2 = 1/2(-6) + b
2 = -3 + b
Add 3 on both sides.
5 = b

y = 1/2x + 5

A circular labyrinth has a circumference of 75 feet what is the distance from the outside edge of the labyrinth in to it center
Bas_tet [7]
The distance from the outside edge of a circle to its centre is given by its radius. The circumference of a circle is given by 2πr, thus if we know that this is equal to 75 feet and using π = 3.14, we get:

75 = 2*3.14*r
r = 11.942
Thus r = 12 ft (to the nearest foot)

The cost of purple dye has been increasing over the last few months, and Robyn uses this dye as part of her tie dye scarf busine
joja [24]

The lowest percentage increase in the cost of dye that would make the scarves unprofitable is 42%

<h3>How to calculate the percentage?</h3>

(Price- Unit Cost)/Price= 20% or 0.2

Price- Unit Cost= 0.2 Price

0.8 Price = Unit Cost

Let Unit Cost be x

Price = x/0.8= 1.25x

Dye is 60% of unit costs= 0.6x

Cost of remaining material= 1 - 0.6x = 0.4x

Unit Cost= Cost of Dye+ Cost of remaining material

So, in order to become unprofitable, Unit Cost must be 1.25x

Therefore

1.25x= Maximum cost of dye+ 0.4x

Maximum Cost of Dye = (1.25-0.4)x = 0.85x

Percentage change in cost of dye= {(0.85x-0.6x)/0.6x}*100= 41.66 or 42%

Therefore, theowest percentage increase in the cost of dye that would make the scarves unprofitable is 42%.
