We will assume that the number is n
one eighth of the number = 1/8 x n = n/8
we know that this result n/8) is less than or equal (<=) 3
therefore, the inequality is:
n/8 <= 3

A faraway planet is populated by creatures called Jolos. All Jolos are either green or purple and either one-headed or two-heade
enyata [817]

A. 260

Explanation

Step 1

Let

\begin{gathered} green\text{ jolos,one-headed jolo=170} \\ \text{Purple ,two-headed jolos=284} \\ one\text{ headed jolos=430} \end{gathered}

as we can see

the total of green-one headed jolo is 170

and the total for one headed jolo is =430

so, the one-headed in counted twice

\begin{gathered} total\text{ of gr}en\text{ jolos= }430-170 \\ total\text{ of gr}en\text{ jolos= }260 \end{gathered}

so, the answer is

A.260

Please help I don't understand!
zmey [24]

Answer:

140

Step-by-step explanation:

The ratio of similitude is 6/5, so the ratio of the areas is (6/5)² = 36/25.

So, the area of XYZ is 100(36/25) = 144, which is about <u>1</u><u>4</u><u>0</u>

We are standing on the top of a 1024 foot tall building and launch a small object upward. The object's vertical altitude, measur
Ne4ueva [31]

Answer:

The highest altitude of that object is 1,600 feet.

Step-by-step explanation:

Given that,

h(t) = -16t^2+192 t+1024

where h(t) is the height of the object after t seconds.

h(t) = -16t^2+192 t+1024

Differentiating with respect to t

h'(t)= -32t+192

Again differentiating with respect to t

h''(t)= -32

To find the maximum or minimum value, first we set h'(t)=0.Then we get a equation of t and solve it. Assume  t=a is the solution of the equation .

Now check h''(t) at t=a, if h''(a)<0 then the function h(t) has a maximum value at t=a

If h''(a)>0 then the function h(t) has a minimum value at t=a.

Now,

-32t+192=0

⇒32t=192

\Rightarrow t=\frac{192}{32}

⇒t= 6

h''(6) = -32<0, So the object reaches at its highest altitude after 6  seconds.

Now plunging t=6 in the given function

h(6)= -16 (6)²+192×6 +1024

     =1600 feet

The highest altitude of that object is 1,600 feet.
