Answer:
X = 1 ; x = 7
Step-by-step explanation:
Given the equation:
s=10|x-4|+50
s = sound level in decibels ; x = number of measures of music played
Take away 50 from Both right hand and left hand side of the equation
Recall s = 80
80 - 50 = 10│x - 4│+ 50 - 50
30 = 10│x - 4│
To get rid of the absolute value sign, append ± to left hand side
± 30 = 10x - 40
Minimum value of x : - 30 + 40 = 10x ; 10 = 10x ; x = 1
Maximum value of x : 30 + 40 = 10x ; 70 = 10x ; x = 7
In math, volume is length x width x height
Answer: -7
Step-by-step explanation: minus and a plus makes a minus, then, add you ad the -5 and -2 which equals -7
Probability is all about multiplying fractions.
The first fraction is the probability of picking a girl.. so how many of the 12 total children are girls. (8/12)
The second fraction is the probability of picking a boy.. so how many of the 11 remaining children are boys. (4/11)
8/12 X 4/11 = 8/33 -> this isn't even an option but I'm like 10000% this is the right answer..
I started off this answer feeling so confident lol. good luck.
Step-by-step explanation:
Let the first angle be x,
second angle= x-45.6°
Now,
x+(x-45.6)°=90°
x+x-45.6°=90°
2x-45.6°=90°
2x=90°+45.6°
2x=135.6
x=135.6/2
x=67.8
Hence,
First angle= x= 67.8°
Second angle= x-45.6°= 67.8°-45.6°= 22.2°
