Answer:
21.1 percent
Step-by-step explanation:
Total balls after -1 red ball=7+5+4+3=19
Prob of purple ball= purple ball/total balls
= 4/19
=0.2105...
percentage:21.1%
Answer:
B) 504
Step-by-step explanation:
They should expect 30% of 40 out of every 300 of the 12,600, so ...
0.30 × 40/300 × 12,600 = 504
About 504 residents might be expected to join.
Answer:
The actual perimeter of the field is 352 meters
Step-by-step explanation:
Given;
the perimeter of a field is 0.352 meters
the actual perimeter of the field is 1,000 times as large
let the perimeter of the field = p
the the actual perimeter of the field = T
Given;
P = 0.352 m
T = 1000 x p
T = 1000 x 0.352
T = 352 m
Therefore, the actual perimeter of the field is 352 meters
Answer:
Step-by-step explanation:
finding PR ( public relations :D , not that PR , the PR on this triangle thingy )
use law of cosines, again
c=sq rt [ a^2+b^2﹣2*a*b*cos(C) ]
where
c=PR
a= 9
b = 22
C = the angle of Q or 180 = 97+24+Q so Q = 180-97-24 = 59°
they tried to trick us.. by not giving us the angle C for the above cosine formula , but we figured out their diabolical plan :D yay super hero math
then
PR = sq rt [ 9^2 + 22^2 - 2*9*22*cos(59) ]
PR = sq rt [ 81 + 484 -203.9550777 ]
( notice that now it is a subtraction sign instead of a plus sign, this time? )
PR = sq rt [361.0449 ]
PR = 19.0011
to the nearest 10th
19.0 :)

Anyways here’s the answer:
160 cm squared.
You find volume by doing length x width x height and then take that answer and divide it by 3. When you do 8x6x10, 480, and 480 divided by 3 is 160.
