Step-by-step explanation:
160% of 19 is 30.4
Convert 160 into a decimal: 160%/100 = 1.6
Multiply the decimal by 19: 1.6 × 19 = 30.4 <-- our answer.
------
0.9% of 54 is 0.486
Convert 0.9% in a decimal: 0.9%/100 = 0.009
Multiply the decimal by 54: 0.009 × 54 = 0.486 <-- our answer.
-------
15% of 376 is 56.4
Convert the percentage into a decimal: 15%/100 = 0.15
Multiply the decimal by 376: 0.15 × 376 = 56.4 <-- our answer.
Answer:
54 degrees and 90 degrees
Step-by-step explanation:
If you add up all the angles in a triangle it will equal 180 degrees. So first, subtract 36 from 180
180 - 36 = 144
If the other two angles have a ratio of 3 to 5 then you need to divide 144 by 8 because 3 + 5 = 8
144/8 = 18
Then multiply 18 by 3 and 5. This will give us the measurement of the other two angles.
18 x 3 = 54
18 x 5 = 90
90 + 54 + 36 = 180
S - the number of the t-shirts;
h - the number of hats:
The system of equations:
s + h = 23
10 s + 12 h = 246
--------------------------
s = 23 - h
10 * ( 23 - h ) + 12 h = 246
230 - 10 h + 12 h = 246
2 h = 246 - 230
2 h = 16
h = 16 : 2
h = 8
s = 23 - 8
s = 15
Answer: The basketball team sold 15 t-shirts and 8 hats.
