Mathematics

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

NEED THIS ANSWER BY THE END OF THE DAY PLEASE HELP !!
Alborosie

Answer:

small number is 14

Larger number is 31

Step-by-step explanation:

Let x = one number

Let y = the second number

x + y = 45

x = y - 17

Put y - 17 into the top equation for x

y - 17 + y = 45

2y - 17 = 45          Add 17 to both sides

2y = 45 + 17

2y = 62                Divide by 2

y = 62/2

y = 31

distance traveled during chase = (88 mph)(0.25 hr) = 22 miles.
