Answer:
240, 1800, 2040
Step-by-step explanation:
First find the surface area of the shape - base = 3 x 15 x 2 + 40 x 15 + 40 x 3 x 2 = 930 m ^2
Now find the area of base = 40 x 15 = 600
Now, the cost of painting = 10 pounds for 25 m^2. SO here cost = 600 / 25 x 10 = 24 x 10 = 240 pounds.
Now cost of tiles = 600 x 3 = 1800
Total cost = 1800 +240 = 2040
Answer:
non-proportional
Step-by-step explanation:
non-proportional because it doesn't pass through the origin.
Answer:
Answer: The car will travel 29 1/3 miles in 44 minutes, 40 miles in an hour
Step-by-step explanation:
1 1/2x2 1/4 = 2/3
Multiply that by your minutes (25) and you will get 16.6666
Convert to a fraction and u will get 16 2/3 miles in 25 minutes
40 miles in an hour
Answer:
approx. 24.6 ft
Step-by-step explanation:
x=the distance of the fire from the base of the tower
200ft=the height of the tower
7 degrees=the angle of depression
Using these values you can draw a diagram that highlights that you need to use trig. to work out the answer.
Using Tan:
Tan 7=x/200 ft
multiply both sides by 200 ft
200*tan 7=24.55691218
approx. 24.6 ft
Answer:
Option 2 is true.
Step-by-step explanation:
Th sum of probabilities of two complementary events is one, which implies
P(A) + P(B) = 1
So,
P(B) = 1 - P(A)
