Answer:

7. This means the cost of the item to you is $52.85. You will pay $52.85 for a item with original price of $75.50 when discounted 30%.

If you buy an item at $75.50 with 30% discount, you will pay 75.50 - 22.65 = 52.85 dollars.

8. Same principle applies

40.99×25/100=10.25

Therefore, 40.99-10.25= 30.74 dollars

9. 30×40/100= 12

30-12= 18 dollars

T(6, 12) is the midpoint of CD The coordinates of D are (6, 15). What are the coordinates of C?

vovikov84 [41]

Answer:

(6,9)

Step-by-step explanation:

Let the coordinates of C be (x,y).

$\frac{6+x}{2}=6 \implies x=6 \\ \\ \frac{15+y}{2}=12 \implies y=15 \\ \\ \therefore C=(6,9)$

1:<br> Convert 170 degrees to radians.

fiasKO [112]

9514 1404 393

Answer:

(17/18)π radians ≈ 2.9670597 radians

Step-by-step explanation:

Radians and degrees are proportional measures of angles. 180° is π radians, so your conversion is ...

radians/degrees = x/170° = (π radians)/180°

x = (π radians)(170/180)

x = (17/18)π radians

flying to munich with a tailwind plane averaged 242 mph. on the return trip the plane only averaged 178 mph while flying back in

Romashka [77]

Answer:

The speed of wind is 32 mile per hour

The speed of plane is 210 mile per hour

Step-by-step explanation:

Given as :

The speed of plane with tailwind = 242 mph

The speed of the return trip = 178 mph

Let The speed of the wind = y mph

The speed of the plane = x mph

Now , According to question

The speed of plane with tailwind = x + y

Or, x + y = 242 mph .......1

and The speed of the return trip = 178 mph

or , x - y = 178 mph ........2

Solving both equations

( x + y ) + ( x - y ) = 242 + 178

Or, 2 x = 420

∴ x = $\frac{420}{2}$

I.e x = 210 mph

Put the value of x in eq 1

I.e x + y = 242 mph

or, 210 + y = 242

∴ y = 242 - 210

I.e y = 32 mph

Hence The speed of wind is 32 mile per hour

And The speed of plane is 210 mile per hour Answer
