Answer:

The numbers are 39 and 14.

Step-by-step explanation:

Equation 1, sum of the numbers:

x + y = 53

Equation 2, difference of the numbers:

x - y = 25

System of equations:

x + y = 53

x - y = 25

----------------

2x = 78

x = 39

Solve for y:

39 + y = 53

y = 14

The numbers are 39 and 14.

Sandy wants to cover a wooden cylinder with a diameter of 1 ft and a height of 4 ft with carpet to build a scratching post for h

aleksley [76]

Answer:

Sandy needs $14.13\ ft^{2}$ of carpet to build a scratching post for her cats

Step-by-step explanation:

Sandy needs to calculate the surface area of the cylinder

The surface area of the cylinder is equal to

$SA=2\pi r^{2}+2\pi r(h)$

we have

$r=1/2=0.5\ ft$ ----> the radius is half the diameter

$h=4\ ft$

assume

$\pi =3.14$

substitute the values

$SA=2(3.14)(0.5)^{2}+2(3.14)(0.5)(4)$

$SA=14.13\ ft^{2}$

Sandy needs $14.13\ ft^{2}$ of carpet to build a scratching post for her cats
