Answer:

100/3 meters per min

Step-by-step explanation:

Im kinda unsure about this one.

It took 3 minutes for John to travel 200m and Sam to travel 300m.

You have time and distance so you can use that to find velocity.

John: 200/3 m/min

Sam: 300/3 m/min

take the difference between the two to get your answer.

|200/3 - 300/3| = 100/3 m/min

A tile factory earns money by a flat fee for delivery and sales price per tile sold. For one customer the tile factory shipped 1

algol13

10,000 tiles * 0.25 = 2500

3000 -2500 = 500

so the delivery fee is 500 and the tiles cost 0.25 each

so the equation would be y = 0.25x +500

Answer is C

Answer:

b= 70

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to exterior angle.

a+b = 140

We know that a = b since PQ = RQ The angles opposite the equal sides in an isosceles triangle are equal

b+b = 140

2b =140

Divide by 2

2b/2 =140/2

b= 70

Two important ingredients for baking bread are yeast and flour. To make a loaf of bread of at most 30 servings, maintain a yeast

IceJOKER [234]

Answer:

If 0.25 oz of yeast is used, then 50oz of flour is needed.

It would require 0.5 oz of yeast for 90 oz the flour.

Step-by-step explanation:

We know that the proportion of yeast (y) and flour (f) is 1: 200 when a maximum of 30 servings of bread is made. This is:

$\frac{y}{f} = \frac{1}{200}$

So if we use 0.25 oz of yeast:

$y = 0.25\\\\y = (f)\frac{1}{200}\\\\0.25 = (f)\frac{1}{200}\\\\0.25 * 200 = f\\\\f = 50\ oz$

if 0.25 oz of yeast is used, then 50oz of flour is needed.

If you make 60 servings of bread with 90 oz. Of flour, then you should keep the following ratio:

$\frac{y}{f} =\frac{1}{180}$

So, if we use f = 90 0z of flour:

$f = 90\ oz\\\\f = 180y\\\\90 = 180y\\\\y = \frac{90}{180}\\\\y = 0.5\ oz$

It would require 0.5 oz of yeast.
