Answer:
12
Step-by-step explanation:
Since 8 poster takes 48 inches of tape
48/8 = 6
each poster will take 6
if you have two posters
6x2=12
so 12
Answer:
Step-by-step explanation:
a) Perimeter of a rectangle = 2 *(L +w)
b) w = L - 2
Answer: B
c) Perimeter = 96 inches
2* (l +w) = 96
2*( L + L - 2 ) = 96 {Combine like terms}
2 * (2L - 2) = 96 {use distributive law}
2*2L - 2*2 = 96
4L - 4 = 96 {Add 4 to both sides}
4L = 96 +4
4L = 100 {divide both sides by 4}
4L/4 = 100/4
L = 25 inches
d) w = L - 2
= 25 - 2
w = 23 inches
There are 4 zeros in 30,000.
Answer:
235 yd²
Step-by-step explanation:
It is convenient to divide the figure into 2 or 3 parts. One is the trapezoid above the dotted line, with parallel bases of length 20 and 35 and height 6. Its area is ...
A = (1/2)(b1 +b2)h = (1/2)(20 +35)·6 = 165 . . . . yd²
Then the remaining two triangles can be rearranged to form a rectangle 10 yards by 7 yards. Its area is the product of those dimensions:
A = L·W = (10 yd)(7 yd) = 70 yd²
The area of the entire figure is the sum of these areas, ...
trapezoid area + rectangle area = 165 yd² +70 yd² = 235 yd²
