3,500,000 - 2,800,000 = 700,000
So the magazine needs 700,000 readers to meet their goal.
Hope that helps you. :-)
Answer:
12
Step-by-step explanation:
Assuming that the shape of the playground is rectangular, we know that the area of a rectangle is length x width.
Let the length = x
width = x + 5
x(x + 5) = 204
x² + 5x = 204
x² + 5x - 204 = 0
(x + 17)(x - 12) = 0
x = -17 and x = 12
However, since x represents the length of the playground, length cannot be negative. The only value possible is x = 12.
Therefore, the playground has a length of 12 yd and a width of 12 + 5 = 17 yd.
Answer:
length = 17 yd, width = 12 yd
Step-by-step explanation:
Answer:
5.5 m
Step-by-step explanation:
Let x be the length of flagpole.
Length of stick=1 m
Length of shadow of stick=1.4 m
Length of shadow of flagpole=7.7 m
According to question
When triangles are similar then their ratio of corresponding sides are equal.
Hence, the length of flagpole=5.5 m
Answer:
....sorry
Step-by-step explanation:
for the second one, remember LW=are for fiding the area of the base,
for cone, base=circle, so therfor V=HB/3, and B=circle=pir^2, so V=(1/3)(hpir^2)
h=17
r=6
V=(1/3)(17(3.14)6^2)
V=17(3.14)12
V=640.56
rond tenth
V=640
