Serggg [28]

Using the slope concept, it is found that the base of the left field wall is 361 feet from a point on level ground directly below the top row.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change.</u>

It's also the tangent of the angle of depression.

In this problem:

The vertical change is of 90 ft.

The horizontal change is of x.

The angle of depression is of 14º.

Hence:

$\tan{14^{\circ}} = \frac{90}{x}$

$0.249328 = \frac{90}{x}$

$0.249328x = 90$

$x = \frac{90}{0.249328}$

$x = 361$

Hence, the base of the left field wall is 361 feet from a point on level ground directly below the top row.

2. Sue is buying a 13-pound mixture of gummy candy, jelly beans, and hard candy. The cost of gummy candy is $1.20 per pound, jel

omeli [17]

Answer:

Store used 7.5 pounds of gummy candy, 2.5 pounds of jelly beans, and 3 pounds of hard candy.

Step-by-step explanation:

Let the amount of gummy candy be 'x'.

Let the amount of jelly beans be 'y'.

Let the amount of hard candy 'z'.

Now Given:

Sue is buying 13 pound of mixture.

So we can say that;

$x+y+z =13$

But Given:

The mixture calls for three times as many gummy candy pieces as jelly beans.

$x=3y$

Substituting the value of x in above equation we get;

$3y+y+z=13\\\\4y +z =13 \ \ \ \ \ equation \ 1$

Also Given:

cost of gummy candy = $1.20

cost of jelly beans = $2.00

cost of hard candy = $2.60

Total Cost of mixture = $21.80

Now Total Cost of mixture is equal to cost of gummy candy multiplied amount of gummy candy plus cost of jelly bean multiplied amount of jelly bean plus cost of hard candy multiplied amount of hard candy.

framing in equation form we get;

$1.2x+2y+2.6z=21.80$
