Katena32 [7]

Answer:

84.4 m

Step-by-step explanation:

We are given that

$\theta=24^{\circ}$

The new angle, $\theta'=38.5^{\circ}$

Slop of the present bank=210 ft

We have to find the horizontal distance into the bank must they dig.

$Sin\theta=\frac{Perpendicular\;distance}{Hypotenuse}$

$sin24=\frac{h}{210}$

$h=210sin24=85.4 m$

$cos\theta=\frac{base}{Hypotenuse}$

$cos24=\frac{x}{210}$

$x=210cos24=191.8 m$

$tan\theta'=\frac{perpendicular\;distance}{Base}=\frac{h}{x'}$

$tan38.5=\frac{85.4}{x'}$

$x'=\frac{85.4}{tan38.5}=107.4 m$

The horizontal distance they have to dug=191.8-107.4=84.4 m

At Danny’s Diner, the bill at one table for three cups of coffee and five omelets is $7.60. The bill at another table for one cu

Firlakuza [10]

Let a cup of coffee be represented by = c

Let an omelet be represented by = o

Part A:

The bill at one table for three cups of coffee and five omelets is $7.60.

So equation is : $3c+5o=7.60$ ...(1)

The bill at another table for one cup of coffee and two omelets is $2.90.

So, equation is : $1c+2o=2.90$ ...(2)

From equation (2) we get $c=2.90-2o$ .... (3)

Part B:

Substituting the value of 'c' from equation (3) in (1)

$3(2.90-2o)+5o=7.60$

$8.7-6o-5o=7.60$

$o=1.10$

As c=2.90-2o

$c=2.90-2(1.10)$

$c=2.90-2.20=0.70$

Part C:

Hence, cost of 1 cup of coffee is $0.70

Cost of 1 omelet is $1.10
