Math hw due tmr...need little help plz!!?!
Oliga [24]
First you gotta find out what this is:
{3}^{9} =

Then you gotta figure out what this is too:
{3}^{5}=
Once you figure that out you must divide:
{3}^{9} \div {3}^{5} =

And the answer of that equation will be the answer to the problem of how many times bigger the capacity of the of the Madison square Garden in NY than the typical movie theater!

Hope it helps Good Luck! ( If I did anything wrong please let me know and Ill fix it :) )

What two facts can you double to find 8x4?

A boat takes 3.6 h to travel downstream from its dock to a fishing hole. If the water were still, it would have taken 4.5 h to m
salantis [7]
Given:

t1 = 3.6 h
t2 = 4.5 h
x = speed of boat
y = speed of water

Required:
a) Expression of distance traveled with moving water with 3.6h
     Expression of distance traveled with moving water with 4.5h
b) Solve for y
c) Percent of boat's speed is the water current

Solution:

Working formula: 
distance = velocity*time

a) For travelling downstream, we get the equation

d = (x +y)*3.6

For travelling upstream, we get the equation

d = (x-y)*4.5

b) Setting the distance as equal for travelling upstream or downstream, we arrive at the equation of

(x+y)*3.6 = (x-y)*4.5
3.6x + 3.6y = 4.5x - 4.5y
8.1y =0.9x
y = x/9

c) percentage = 1/9*100% = 11.1%

<em>ANSWERS: a) d = (x+y)*36; d = (x-y)*4.5
</em>
                     <em>b) y = x/9
</em>                     <em>c) 11.1%</em>

An escalator lifts people to the second floor of a building, 21 ft above the first floor. the escalator rises at a 30 degree ang
Ira Lisetskai [31]
We use the trigonometric function for this case. An escalator is an inclined path. We form a right triangle since we have given the value of the height. The height from the first floor to second floor is called the adjacent while the travelled distance of the people is called the hypothenuse. We use cosine function because we are given in terms of adjacent and hypothenuse. The ratio of cosine function is
cos x = a/h
where x is the angle
Solving for h,
h = a/(cos x) = 21/(cos 30) = 24.25 ft
