L = 6W ---- the lenght is 6 times its width
P = 2(L + W) = 140
A =?

P = 2(L+W)
P = 2L + 2W
we know that L = 6W so we plug it into the equation
P = 2(6W) + 2W= 140
    12W + 2W = 140
14W = 140
W = 140/14
W = 10 

Lets plug 10 into the equation L = 6W
L = 6(10)
L = 60

AREA = LW
= 60 * 10
= 600

1) A group of five friends goes to the state fair. Each friend pays the entrance fee and buys
kari74 [83]

Answer:

5(d - 4)

Step-by-step explanation:

Entrance fee per head = d

Entrance fee for the 5 friends = 5*d = 5d

Booklet of ride ticket per head = 2.5d

Booklet of ride ticket for the 5 friends = 5(2.5d)

Meal ticket per head = d - 4

Meal ticket for the 5 friends = 5(d - 4)

Total amount paid altogether by the five friends = 5d + 5(2.5d) + 5(d - 4)

From this breakdown above, the total amount paid by the 5 friends for their meal tickets = 5(d - 4)

"I have a 35% off coupon that I would like to apply to my purchase today. How much will the coupon save me?" Employee: "It looks
I am Lyosha [343]

Answer:

$43.75

Step-by-step explanation:

So you have: 35% discount

Total without discount: $125.00

Amount discounted: ?

So you have to make 35% into a number that you can multiply with $125. When you have a percentage you move the decimal two times to the front so you have 0.35 then you multiply;

125 x 0.35 = 43.75.

43.75 is the amount discounted, so you only have to pay 81.25. The equation for that would look like;

125 - 43.75 = 81.25

Hope that made sense!

Simplify square root of (1-sin theta)(1+sin theta)
Vinil7 [7]
Recall the important identities:

i) (a-b)(a+b)= a^{2}- b^{2}, the difference of squares formula.

ii) sin^{2} x+cos^{2}x=1, for any angle x.

Then,

from i)

\sqrt{(1-sin(theta))(1+sin(theta))}= \sqrt{1- sin^{2}(theta) }

then, from ii), we have 

\sqrt{1- sin^{2}(theta) }= \sqrt{cos^{2}(theta) }=cos(theta)


Answer: cos(theta)
