90/x=100/18 (90/x)*x=(100/18)*x - multiply both sides of the equation by x 90=5.55555555556*x - divide both sides of the equation by (5.55555555556) to get x 90/5.55555555556=x 16.2=x x=16.2 18% of 90=16.2
The answer to you problem is 16.2, the equation you needed was, 90/0.18

A sandbox is 1 1/3 feet tall, 1 5/8 feet wide,and4 1/2 feet long. How many cubic feet of sand will it hold
Answers
volume=legnth times width times height convert all to iimporper fractions first for ease 1 and 1/3=1+1/3=3/3+1/3=4/3
1 and 5/8=1+5/8=8/8+5/8=13/8
4 and 1/2=4+1/2=8/2+1/2=9/2
multiply them volume=(4/3) times (13/8) times (9/2) volume=(4 times 13 times 9)/(3 times 8 times 2) volume=468/48 volume=39/4 volume=9 and 3/4 cubic feet
Volume (sandbox)= long x wide x tall
long=4 1/2 ft=(4+1/2) ft=(8+1)/2 ft=9/2 ft wide=1 5/8 ft=(1+5/8)ft= (8+5)/8 ft=13/8 ft tall=1 1/2 ft= (1+1/2)ft=(2+1)/2 ft=3/2 ft
Volume=9/2 ft * 13/8 ft * 3/2 ft=(9*13*3) / (2*8*2) ft=351/32 ft³
V = A * h; V = volume of the building; h = 35 m ; A = the area of floor plan; A = 30 ^2 + π*15^2 - (π*15^2) / 4 => A = 900 + π*675 / 4 ≈ 900 + 3.14*675 / 4 ≈ 900 + 529.87 ≈ 1429.87m^2 V ≈ 50045.45 m^3
The area of the base of a prism is 60mm. The perimeter of the base is 40mm. The height of the prism is 8mm. What is the surface area of the prism?A. 168mm B. 380mm C. 440mm D. 560mm
Answers
B) 380mm
Surface area = Perimeter of the base x height + the area of the base Surface area = 40 x 8 + 60 Surface area = 320 + 60 Surface area = 380 mm
Please help anyone please?
