Step-by-step explanation:
850-250= 600
40*15= 600
Find the total square footage of each room. The room will be a rectangle and finding the area of a rectangle is just the length times the width
area of rectangle = lw
area of each room = 14 x 20.5 = 287 ft^2
The 4 rooms each have the same square footage.
Total square footage of all rooms = 287 x 4 = 1148 ft^2
To find how many roles of carpet are needed, divide the footage needed to be covered by the footage per carpet
1148/200 = 5.74
You can't buy 5.74 of a carpet roll, so you will need 6 rolls :)
Hope I helped
The volume of the square pyramid is 6 x 6 x 9/3 = 108 cubic cm.
Volume of the cube = 4 x 4 x 4 = 64 cubic cm
Number of cubes needed: 108/64 = 1 11/16 cubes (1.6875)
Answer:
1042
Step-by-step explanation:
-38,-8,22,52
The common difference is 52 - 22 = 30
a_1 = -38
a_2 = -38 + 30
a_3 = -38 + 2 * 30
a_4 = -38 + 3 * 30 (notice that the common difference is multiplied by 1 less than the term number)
a_n = -38 + (n - 1)30 (since the term number is n, we multiply the common difference by n - 1)
a_n = -38 + 30(n - 1)
a_37 = -38 + 30(37 - 1)
a_37 = 1042
