I would say both because it says that they both weigh the exact same.

It would be the same because it said that they are the same weight in the afternoon and morning.

If the slope of a line is -1 and two points on the line are (-9, 3) and (-10, r), what is the value of r?

ANEK [815]

Answer:

$r=4$

Step-by-step explanation:

We know that the slope of the line is -1.

We also know that the line passes through (-9, 3) and (-10, r).

We want to find the value of r.

First, let's figure out the equation of our line. We can use the point-slope form:

$y-y_1=m(x-x_1)$

Where m is the slope and (x₁, y₁) is a point.

So, let's substitute -1 for m. Since we know the point (-9, 3), let's use this for (x₁, y₁).

Substitute:

$y-(3)=-1(x-(-9))$

Simplify:

$y-3=-(x+9)$

Distribute:

$y-3=-x-9$

Add 3 to both sides. So, our equation is:

$y=-x-6$

It passes through (-10, r) and we want to find the value of r. So, let's substitute -10 for x and r for y, since -10 is our x and r is our y. So:

$r=-(-10)-6$

Evaluate for r. Distribute:

$r=10-6$

Subtract:

$r=4$

So, the value of r is 4.

And we're done!

Min works in the kitchen of a catering company. Today her job is to cut whole pita bread into small triangles. Min uses a cuttin

Ilia_Sergeevich [38]

The number of squares of whole pita bread Min will have to cut up is;

<u><em>21 squares of whole pita bread</em></u>

Since the triangle is isosceles, and has base of 4 cm with 2 equal sides of 6 cm, it means the height is 5.7 cm.

Thus, area of triangle is;

A = ¹/₂ × 4 × 5.7

A = 11.4 cm²

She will cut 3 pita triangles for every guest. This means that;

Area for each guest = 3 × 11.4 = 33.2 cm²

There are 250 guests and so the total needed for the 250 guests is;

Total area = 250 × 33.2

Total area of pita bread = 8300 cm²

The bread comes in 20 cm sides of a square shape.

Area of square = 20 × 20 = 400 cm²

Number of squares of whole pita bread she will have to cut = 8300/400

⇒ 20.75 ≈ 21 squares of whole pita bread
