on a certain planet, objects weight about 7/12 of what they weigh on earth. an object weights 13 5/12 pounds on the planet. solv

Cloud [144]

Although the concept here is physics, the solution is technically just algebra. You have two situations that are related to each other which can be expressed in equation form. Actually, the equation is already given which is <span>7/12 w= 13 5/12. So, basically, all you have to do is solve for w.

Let's simplify 13 5/12 first into an improper fraction.You do this by multiplying the denominator with the whole number and adding to it the numerator. This will be your new numerator, The denominator would still be 12. So, this is equal to (12*13 + 5)/12 = 161/2. Then,

(7/12) w = 161/12

By cross multiplication,

7*12*w = 161*12
w = 161/7 = 23

Therefore, w = 23 pounds which is the weight of the object on Earth.

An art exhibit at a local museum features several similarly shaped metal cubes welded together to make a sculpture. The smallest

borishaifa [10]

Answer: Length of other edges will be 7.5 inches, 8 inches, 9 inches, 10.5 inches, 12 inches.

Explanation:

Length of smallest cube = 6 inches

Ratio of similarity to the smallest cube is given as follows:

1) 1.25

So, length of other edge will be

$1.25\times 6=7.5\ inches$

2) 4:3

So, the length of other edge will be

$\frac{4}{3}\times 6=8\ inches$

3) 1.5

So, length of other edge will be

$1.5\times 6=9\ inches$

4) 7:4

So, length of other edge will be

$\frac{7}{4}\times 6=10.5\ inches$

5) 2

So, length of other edge will be

$2\times 6=12\ inches$

A right cylinder has a radius of r inches and height of 2r inches.

Bess [88]

Answer:

the volume is $6.28r^{3}$ $in^{3}$

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cylinder.

Given data

Volume v = ?

Radius r = r in

Height h= 2r in

We are expected to solve for the volume of a cylinder, given the above data we can substitute it in the formula for volume of a cylinder to obtain our result

we know that the expression for the volume of a cylinder is

$v= \pi r^{2} h$

$v= 3.142*r^{2} *2r\\v= 3.142*2r^{3} \\v= 6.28r^{3} in^{3} \\$

Hence the volume in terms of the radius is $6.28r^{3}in ^{3}$
