ANSWER

You're going to learn how to determine areas and volumes of regular pyramids. ... In fact, the volume of any pyramid is one-third the area of the base times the height. Volume of a Pyramid Formula. Finding the surface area of a pyramid is done by first finding the area of the base and the area of each lateral face.

To travel 105 miles, it takes Sue, riding a moped, 3 hours less time than it takes Doreen to travel 64 miles riding a bicycle. S

Volgvan

Let t=time Doreen travels; let r=rate of Doreen

RATE * TIME = DIST.
Sue | r+13 t-3 105
Doreen | r t 64

Now solve the system:
(r+13)(t-3)=105
r*t=64

 $r= \frac{64}{t} 
\\
\\(\frac{64}{t} +13)(t-3)=105 
\\
\\64- \frac{192} {t}+13t-39-105=0
\\
\\13t- \frac{192} {t}-80=0
\\
\\ 13t^2-80t-192=0
\\
\\t_{1,2}= \frac{80\pm \sqrt{(-80)^2-4\times13(-192)} }{2\times13}= \frac{80\pm128}{26} 
\\
\\t=\frac{80+128}{26} =8
\\
\\r=\frac{64}{t} =\frac{64}{8} =8$ 

Doreen: rate = 8 mph, time = 8 hours
Sue: rate = 21 mph, time = 5 hours

If AC = 40, find the length of JK.

lesantik [10]

Answer:

JK = 24

Step-by-step explanation:

Δ BKJ and Δ BCA are similar triangles and ratios of corresponding sides are equal, that is

$\frac{JK}{AC}$ = $\frac{BK}{BC}$ , substitute values
