Answer:
791.2 ft
Step-by-step explanation:
The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.
where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then
9514 1404 393
Answer:
$181.19
Step-by-step explanation:
The coupon means you will pay 70% of the bill. The tax means you will pay 105.65% of the amount after the coupon is applied. Your final bill is ...
$245 × 0.70 × 1.0565 ≈ $181.19
_____
Your bill after the coupon is applied will be ...
bill - 0.30×bill = bill(1 - 0.30) = bill×0.70
The amount after tax is added is ...
charge + 0.0565×charge = charge(1 +0.0565) = charge×1.0565
Since the final bill is the product of these factors, the order of application does not matter. Conventionally, tax is applied last, so that accounting with the tax collection authority is properly maintained.
The value of x° is 22° and exterior angle is 25.
Step-by-step explanation:
l can prove like this,
Here,2x°+(103-x)°=(6x-7)°...Being exterior angle
or,2x°+103°-x°=6x°-7°
or,x°+103°=6x°-7°
or,103°+7°=6x°-7°
or,5x°=110°
or,x°=110°÷5=22°
Now,
x°=22°
(6x-7)°=(6×22-7)°=125°
