The area formula for rectangles is lxw. To solve, I would divide the figure up into 3 rectangles- top,middle and bottom, then find the areas and add them together.
Top: 4x13=52 cm^2
Middle: 5x8=40 cm^2
Bottom: 21x10=210 cm^2
(5 is the width of the middle piece. You get it from subtracting. 21-8-8=5. 13 is the width of the top piece. 5+8=13)
52+40+210
=302 cm^2
So your answer is 302 square centimetres.
This can be treated as a proportion problem.
Larger solid:
Surface area = 1,372 cm²
Volume = 1,801 cm³
Smaller solid:
Surface area = 1,008cm²
Volume = ?
1,372 / 1,801 = 1008 / x
1,372 * x = 1,801 * 1008
1,372x = 1,815,408
x = 1,815,408 / 1,372
x = 1,323.18
The volume of the smaller solid is 1,323.18 cm³
A) Toys R Us - 6.25 / 5 = 1.25
b) Walmart - 12.64 / 10 = 1.264
c) Target - 2.76 / 2 = 1.38
So Toys R Us has the best unit rate (cheapest)
The number of words x tina can type per minute is at least
50. The inequality that represent the phrase “at least” is greater than or
equal to because at least means that you can reach that amount or higher.
X >= 50
