Please help with this too

vovikov84 [41]

Answer:

Step-by-step explanation:

Garden roller is in the shape of cylinder.

So, one revolution = Curved surface area of the cylinder

diameter = 70 cm

radius = 70/2 = 35 cm

h = 100 cm

Curved surface area of the cylinder = 2πrh

= $2*\frac{22}{7}*35*100$

= 22000 square cm

Area covered in 15 revolutions = 15 * 22000

= 330000 square cm

2) Coin

diameter = 22 mm

r = 22/2 = 11 mm

Volume of coin = 66 mm

πr²h = 66

$\frac{22}{7}*11*11*h=66\\\\\\h=\frac{66*7}{11*11*22}\\h=0.17 mm$

If f(x) = 7 + 4x and g (x) = StartFraction 1 Over 2 x EndFraction, what is the value of (StartFraction f Over g EndFraction) (5)

Degger [83]

Answer:

$\frac{f}{g}(5)$ = 270 ⇒ Last answer

Step-by-step explanation:

* If f(x) = 7 + 4x

* If g(x) = $\frac{1}{2x}$

* We want to find $\frac{f}{g}(5)$

- Lets find at first $\frac{f}{g}(x)$

∵ f(x) = 7 + 4x

∵ g(x) = $\frac{1}{2x}$

∴ $\frac{f}{g}(x)=\frac{7+4x}{\frac{1}{2x}}$

- Lets divide the numerator by the denominator

∵ The numerator is 7 + 4x

∵ The denominator is $\frac{1}{2x}$

∴ (7 + 4x) ÷ $\frac{1}{2x}$

- Lets reverse the division sign to multiplication sign and reciprocal

the fraction after the division sign

∴ (7 + 4x) × $\frac{2x}{1}$

∴ $\frac{f}{g}(x)$ = 2x(7 + 4x)

∴ $\frac{f}{g}(x)$ = 14x + 8x²

- Now substitute x by 5

∴ $\frac{f}{g}(5)$ = 14(5) + 8(5)² = 70 + 200 = 270

∴ $\frac{f}{g}(5)$ = 270

2. You are trying to determine which box of Honey Nut Cheerios to buy, The Family Size box weighs

Katyanochek1 [597]

Answer:

Mega Size

Step-by-step explanation:

Given

Family Size

$Weight = 19.5\ oz$

$Cost = \$3.64$

Mega Size

$Weight = 29.4\ oz$

$Cost = \$4.98$

Required

Determine which has a better value

First, we calculate the unit rate of both.

$Unit\ Rate = \frac{Cost}{Weight}$

For the family size:

$Unit\ Rate = \frac{\$3.64}{19.5\ 0z}$

$Unit\ Rate = \$0.187\ per\ 0z$

For the mega size:

$Unit\ Rate = \frac{\$4.98}{29.4\ 0z}$

$Unit\ Rate = \$0.169\ per\ 0z}$

By comparing the unit rates, the mega size has a better value because it costs cheaper per unit rate
