Answer: angle A=40, Angle B=74, Angle C=66
Step-by-step explanation:
We all know that a triangle has 180 degrees.
3x-8+5x-6+4x+2=180
12x-12=180
12x=180+12
12x=192
x=16.
∠A=2(16)+8=40
∠B= 90-16=74
∠C = 5(16) -14= 66
Answer:
1: $1200
2: Food ($6000)
3: $3000
4: $1800
5: $3000
Step-by-step explanation:
1: 10%*12000 = 1200
2: Food 50%*12000 = 6000
3: 25%*12000 = 3000
4: 15%*12000 = 1800
5: Food - Education = 6000 - 3000 = 3000
Answer:
a.
Step-by-step explanation:
its the right way
Total seats: 52 x 7 + 8 x 12 = 364 + 96 = 460
Total cost for total seats = 460 x 23 = 10,580
Cost for buses: 150 x 7 + 80 x 8 = 1050 + 640 = 1690
Total cost = 10,580 + 1,690 = $12,270
Answer:
4/33
Step-by-step explanation:
We seek to find the repeating decimal 0.121212... in the form of a fraction.
First, set x equal to this decimal:
x = 0.121212...
Multiply both sides by 100:
100x = 12.121212....
Now, let's subtract the original equation from this new one:
100x = 12.121212....
- x = 0.121212....
We realize that since the repeating decimal part goes on forever, we can simply cancel it out when we subtract. So we're left with:
100x - x = 12 - 0
99x = 12
Divide both sides by 99:
x = 12/99 = 4/33
The answer is 4/33.
