Answer:
<u>The original number is 96.875</u>
Step-by-step explanation:
Let's find the original number using the Direct Rule of Three, this way:
Percentage Number
100 x
96 93
***********************************************
96x = 93 * 100
96x = 9,300
x = 9,300/96
x = 96.875
<u>The original number is 96.875</u>
Answer: 8.69 (read explanation)
Step-by-step explanation:
If the one above it is only 8 and x is slightly better it would make much more sense for it to be 8.69..... try it, it sounds quit accurate.
He can make 5 sculptures.
We divide the amount of clay, 14 pounds, by the amount it takes to make one sculpture, 2 4/5 pounds:
14 ÷ 2/45 = 14 ÷ 14/5 = 14/1 ÷14/5 = 14/1 × 5/14 = 70/14 = 5
7 cups; there are two cups per pint, so three and a half pints equals seven cups of milk.
The answer is 36°.
Complementary angles are those angles whose sum is 90°.
Let angles be x and y.
x + y = 90°
x : y = 2 : 3
_____
3 * x = 2 * y
3x = 2y
x + y = 90°
_____
x = 2/3*y
x + y = 90°
2/3y + y = 90°
2/3y + 3/3y = 90°
5/3y = 90°
5y = 90° * 3
5y = 270°
y = 54°
x + 54° = 90°
x = 90° - 54°
x = 36°
The smaller angle is 36°
