In right trapezoid MNPQ

Gala2k [10]

Answer:

about 252.78 ft

Step-by-step explanation:

Define angle QMP as α. Then ...

MN = 60·sin(α)

NP = 60·cos(α)

area MPN = (1/2)(MN)(NP) = 1800sin(α)cos(α)

PQ = 60tan(α)

area MPQ = (1/2)(MP)(PQ) = 1800tan(α)

The ratio of areas is 2.5, so we have ...

1800tan(α) = 2.5·1800sin(α)cos(α)

1 = 2.5cos(α)² . . . . . . divide by 1800tan(α)

cos(α) = √0.4 . . . . . . solve for cos(α)

Then the perimeter is ...

Perimeter = MN +NP +PQ +QM = 60sin(α) +60cos(α) +60tan(α) +60/cos(α)

= 60(sin(α) +cos(α) +tan(α) +sec(α))

= 60(0.774597 +0.632456 +1.224745 +1.581139)

= 60(4.212936) = 252.776

The perimeter of the trapezoid is about 252.776 feet.

_____

With perhaps a little more trouble, you can find the exact value to be ...

perimeter = (6√10)(7+√6+√15)

rosijanka [135]

Answer:

$9398.50

Step-by-step explanation:

Given

$\$1 = 106.40\ ALL$

Required

Equivalent of 1,000,000 ALL

We have:

$\$1 = 106.40\ ALL$

and

$\$x = 1000000\ ALL$

Cross Multiply

$x * 106.40 = 1 * 1000000$

$106.40x = 1000000$

Solve for x

$x = 1000000/106.4$

$x = \$9398.50$ -- Approximated

For what value of q is in the question -13(q+4)=7q+16

Rufina [12.5K]

Answer:

q=-3 2/5

Step-by-step explanation:

First multiply -13 with (q+4)

-13q-52=7q+16

Now you have to change the order before = the numbers with q and after = the numbers without anything

-13q-7q=52+16

Remember that when you change positions the symbol too

Then solve it

-20q=68

Now u have to divide as i do

q=68/-20

you can simplify it

q=3 8/-20

Now divide by the greater divisor in this case is 4

q=3 2/-5

And organize it

q=-3 2/5

Never forget to do q=(answer)

Hopefully it helps.
