The sum of 1/3 and twice a number is equal to 2/3 subtracted from three the number.find the number

Zigmanuir [339]

The number = y

2y + 1/3 = 2/3 - 3y
(add 3y to both sides)
5y + 1/3 = 2/3
(subtract 1/3 from both sides to isolate y)
5y = 1/3
(divide by 5)
y = 1/15

Sergio works at a bakery and needs to cover

Elan Coil [88]

Answer:

The surface area that Sergio needs to frost on each cake is 3,238 square centimeters

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The surface area of the cylindrical cake is equal to the lateral area plus the area of the top of cylinder (remember that the bottom of the cake does not need frosting)

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

we have

$r=40.2/2=20.1\ cm$ ---> the radius is half the diameter

$h=15.6\ cm$

$\pi=3.14$

substitute the given values

$SA=(3.14)(20.1)^{2}+2(3.14)(20.1)(15.6)$

$SA=1,268.59+1,969.16\\SA=3,237.75\ cm^2$

Round up to the nearest whole number

$SA=3,238\ cm^2$

therefore

The surface area that Sergio needs to frost on each cake is 3,238 square centimeters
