Hi can anyone help me with all three questions I have not been taught this topic

Mathematics
1 answer:
scoundrel [369]3 years ago
4 0

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

Mr.Johnson weighs 135 pounds. Her husband weighs 80 kilogram. How many fewer pounds does Ms.Johnson weigh than her husband?
sweet-ann [11.9K]
First you convert kilograms to pounds,
1 kilogram = 2.205 pounds
next you times the number of pounds per kilogram by the number of kilograms given that need to be turned into pounds.
80 times 2.205 = 176.4
next you subtract to get the answer
176.4 - 135= 41.4
so Ms. Johnson weighs 41.4 pounds less than herr husband
