Answer:
a = 170
Step-by-step explanation:
0.3a = 51
a = 51 : 0.3
a = 51 : 3/10
a = 51 x 10/3
a = 510/3
a = 170
0.3x170 =
= 3/10x170
= 510/10
= 51
Answer:
D.
Step-by-step explanation:
Answer:
<em>There</em><em> </em><em>is</em><em> </em><em>no</em><em> </em><em>atta</em><em>chment</em><em> </em><em>showing</em><em> </em><em>a</em><em> </em><em>diag</em><em>ram</em><em>,</em><em> </em><em>so</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>to</em><em> </em><em>you</em><em>r question</em><em> is</em><em> </em><em>unk</em><em>nown</em><em>.</em>
70dB is represented by 100cars in 60sec. Therefore if the number of cats is reduced by 3/4 in the same amount of time(60s), then the decibel level will reduce by 3/4 also. So 70dB * .25= 17.5dB
2 3/4 * 3.36 / (1 2/5)
=11/4 * 3.36 / (7/5)
= 9.24 / (7/5)
= 9.24 / 1.4
= 6.6
