If it’s asking for the area then the formula is:
A= 1/2 b*h

A= Area B= Base h= Height

But if it’s asking for the perimeter then the formula is:
P= a+b+c

P= Perimeter A=side B= side C= base

Hope this helps!

Space Shuttle Marion is observing the launch of a space
Vera_Pavlovna [14]

Using the slope concept, it is found that the shuttle traveled 3.2 miles while Marion was watching.

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

The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.

Initially, the angle of elevation is of 16º, with an elevation of 1 mi, hence:

\tan{16^\circ} = \frac{1}{x_1}

x_1 = \frac{1}{\tan{16^\circ}}

x_1 = 3.5

Then, at the end, the angle will be of 74º, with the elevation remaining constant, hence:

\tan{74^\circ} = \frac{1}{x_2}

x_2 = \frac{1}{\tan{74^\circ}}

x_2 = 0.3

The distance is:

d = x_1 - x_2 = 3.5 - 0.3 = 3.2

The shuttle traveled 3.2 miles while Marion was watching.

What will the last payment be to pay off a $1,250 computer plus 8% sales tax with monthly payments of $120?
GrogVix [38]
Convert 8% too decimal form = 8/100 = .08
1250 * .08 = 100
1250 + 100 = 1350
To find out how many payments of 120 can be made :
120x = 1350
divide both sides by 120
x = 11.25 payments of $120
since .25 is a fraction calculate the actual $ amount by mult. 120 * .25 = $30
The last payment is $30
