Answer:

Step-by-step explanation:

The volume of the pyramid = (1/3)*area of base *height

= (1/3)*10*24*13 = 1040 cubic units.

The total surface area = area of rectangular base + area of 2 isosceles triangles with a base of 24 units + area of 2 isosceles triangles with a base of 10 units.

Area of rectangular base = 24*10 = 240 sq units.

The slant height of isosceles triangles with a base of 24 units = [(10/2)^2+13^2]^0.5 = [25+169]^0.5 = 194^0.5 = 13.92838828 units.

The area of 2 isosceles triangles with a base of 24 units 2*24*13.92838828/2 = 334.2813187 sq units.

The slant height of isosceles triangles with a base of 10 units = [(24/2)^2+13^2]^0.5 = [144+169]^0.5 = 194^0.5 = 17.69180601 units.

The area of 2 isosceles triangles with a base of 10 units 2*10*17.69180601/2 = 176.9180601 sq units.

The total surface area of the pyramid = 240 + 334.2813187 + 176.9180601 = 591.9731247 sq units.

The mean weight of 3 people in a lift was 68kg. If 2 of them weighed 58kg each, how much did the third person weigh?
rusak2 [61]

Answer:

88kg

Step-by-step explanation:

Mean= sum of weights/ Number of people

or, 68= 58+58+x/3

or, 68 * 3= 58+58+x

or, 204=116+x

or, x= 204-116

or,x= 88

Therefore, the weight of third person was 88 kg

(Brainliest for correct answer) Use the above graph to answer the following question. A move from point S to point U indicates
rusak2 [61]
The point s is where the suppl curve and demand curve meet. Hence moving down to point U would indicate an increase in quantity demanded because a shift to the right on supply curve, ie moving down to point u from point s indicates an increase in supply so that means an increase in quantity demanded. If it were to move the other way, ie to the left, then it would show a decrease in supply and a decrease in quantity demanded.
Hope this helps! Any questions please just ask! Thank you so much!!
