Answer:

Possible base lengths are 1, 2, 3, 4, 5

Step-by-step explanation:

Area = base x height / 2

Let base be b

b x 8 / 2 < 24 (Area < 24)

4b < 24

b < 6

15. If y varies directly as x and y = 540 when x = 10, find x when y = 1080

Sholpan [36]

$\qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad \stackrel{\textit{constant of variation}}{y=\stackrel{\downarrow }{k}x~\hfill } \\\\ \textit{\underline{x} varies directly with }\underline{z^5}\qquad \qquad \stackrel{\textit{constant of variation}}{x=\stackrel{\downarrow }{k}z^5~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}$

$\stackrel{\textit{"y" varies directly as "x"}}{y = kx}\qquad \textit{we also know that} \begin{cases} y = 540\\ x = 10 \end{cases}\implies 540=k(10) \\\\\\ \cfrac{540}{10}=k\implies 54=k~\hfill \boxed{y=54x} \\\\\\ \textit{when y = 1080, what is "x"?}\qquad 1080=540x\implies \cfrac{1080}{540}=x\implies 2=x$

The time, in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters

Serhud [2]

Answer:

$d=\dfrac{t^2}{a}$

Step-by-step explanation:

The time in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given by this equation.

t = va

We need to find the expression for d in terms of t and a.

As velocity = distance/time

$t=\dfrac{d}{t}a\\\\t^2=da\\\\d=\dfrac{t^2}{a}$
