ANSWER
450lb
EXPLANATION
If the weight, m of an object on the moon varies directly as the weight of an object e, on the earth, then we can write the mathematical statement,.
We introduce the constant of proportionality to obtain,
When, m=95, e=570,
This implies that,
The equation now becomes,
We want to find e, when m=2700,
The denominator.....i dont really understand the question
Hello,
26r^3s+52r^5-39r²s^4
=13r²(4r^3+2rs-3s^4)
Answer:
Length, l = 10 m, breadth = 8 m
Step-by-step explanation:
Let l be the length and b be the width of the rectangle.
The area of a rectangle is given by :
A = lb
80 = lb ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
36 = 2(l+b)
18 = (l+b) ....(2)
We need to solve equation (1) and (2). On solving we get :
l = 10, b = 8
So, the dimensions of the shop is 10 m and 8 m.
The surface area of the new figure is 1470 square meters, if the edge length of the smaller cube is half the edge length of the cube below and edge length of bottom cube is 14 m.
Step-by-step explanation:
The given is,
Length of Bottom (larger) cube is 14 meters
Step:1
Surface area of new figure = (Surface area of smaller cube) +
(Surface area of bottom (larger) cube)....(1)
Step:2
Surface area of Bottom(larger) cube is,
..............................................(2)
From given, a = 14 m
Equation (2) becomes,
Surface area of bottom cube, A = 1176 square meters
Step:3
Surface area of smaller (top) cube is,
....................................................(3)
From given, a = 7 m ( ∵ The edge length of the smaller cube is half the edge length of the cube below)
Equation (2) becomes,
Surface area of bottom cube, A = 294 square meters
Step:4
From equation (1),
Surface area of new figure = 1176 + 294
= 1470
Surface area of new figure = 1470 square meters
Result:
The surface area of the new figure is 1470 square meters, if the edge length of the smaller cube is half the edge length of the cube below and edge length of bottom cube is 14 m.
