From the equation, it looks like we can set up a triangle like this.  One side is x and the other is x + 20 because the northbound car traveled 20 miles farther.  The hypotenuse is 100 because they were 100 miles apart.

Next, we can use the Pythagorean Theorem to solve for x:

a² + b² = c²
x² + (x + 20)² = 100²

This simplifies to:

x² + x² + 40x + 400 = 10000
2x² + 40x = 9600
2x² + 40x - 9600 = 0

After that, we can divided each side by 2:

x² + 20x - 4800 = 0

Next, we have to factor:

(x - 60)(x + 80) = 0
x = 60, -80

Since we know that distance can't be negative, 60 is the valid answer in this case.

x = 60
x + 20 = 80

Using this information, we know that the westbound car traveled 60 miles and the northbound car traveled 80 miles.

Rockin' Reggie's Music Shop sells about 200 guitar picks each week. Reggie orders picks by the gross (144) from a distributor. A
Gala2k [10]

Answer:

1872 gross should Reggie order for a three month supply.

Step-by-step explanation:

Given:

200 guitar picks each week.

To Find:

How many gross should be ordered for three months period

Solution:

Now  the guitar picks corresponds to the  order picks by gross as follows;

given that 200 guitar picks corresponds to 144 gross orders

Now 200 are sold for each weeks i.e 7 days

<em>Now for 3 months there are approximately 13 weeks </em>

so Total sell for 3 months=13*200=2600 guitars

Now The ratio of guitar picks to gross orders is ,

144/200

=1/1.39=0.72

So 2600 guitars corresponds to 2600*(1/1.39)

i.e. 2600/1.39

=1872 Gross orders are required to get three month of supply

Answer:

A. Plant 1 is growing at a faster rate than Plant 2.

Step-by-step explanation:

The slope (m) or rate of growth in Plant 1 is;

m = Change in y ÷ change in x

m =  \frac{3.5 - 1.5}{1 - 0} = 2

The linear equation of growth in Plant 1 is;

\frac{y - 1.5}{x - 0} = 2

y = 2x + 1.5

The equation of growth in Plant 2 is; y = 1.5x + 3 (slope of 1.5)

Since the slope in growth of Plant 1 is greater than that in Plant 2, it implies then that Plant 1 is growing at a faster rate than Plant 2.
