Juli2301 [7.4K]

Walk = x + 6
Bike = x
Driven = x

x + x + x + 6 = 24
combine like terms

3x + 6 = 24
subtract 6 from both sides

3x = 18
divide both sides by 3 to isolate x

x = 6

Walk = x + 6 = 6 + 6 = 12

12 students walk to school.

Zanzabum

Answer:

$755.98 ft^2$

Step-by-step explanation:

Height of the Cylinder= 30 feet

Diameter = 8 feet

Radius= Diameter/2 = 8/2 = 4 feet

The Amount of Metal Sheet used in constructing the tank is the Total Surface Area of the Tank.

Total Surface Area of a Cylinder =

$=2\pi r(r+h)\\=2*\pi*4(4+30)\\=8*\pi*30=\\=240\pi\\=755.98 ft^2$

Diameter of the semicircle = 10 km.

Explanation: perimeter of semicircle = 1 2

the circumference + diameter Given: perimeter of semicircle = 25.7 k m

Circumference of circle with radius r = 2 π r where 2 r = diameter ⇒ 25.7 = 22 π r + 2 r ⇒ 25.7 = π r + 2 r = r ( π + 2 ) ⇒ 25.7 = r ( 3.14 + 2 ) = r ( 5.14 ) ⇒ r = =5m ⇒d i a m e t e r = 2 r = 10 k m
