Answer:
216π cubic centimeters
Step-by-step explanation:
Answer:
(B)5200
Step-by-step explanation:
Since the value was increased by 30%, the new value in the options is 130% of the initial Value.
Let x be the number of hex nuts in the bin before that delivery.
130% of x = New Value
![\frac{130}{100} \: of\: x =New \: Value](https://tex.z-dn.net/?f=%5Cfrac%7B130%7D%7B100%7D%20%5C%3A%20of%5C%3A%20x%20%3DNew%20%5C%3A%20Value)
1.3 of x = New Value
x= New Value ÷ 1.3
Since the number of hex nuts in the bin is a whole number, we test the options to see which satisfies this condition.
- 5100 ÷ 1.3 =3923.08
- 5200 ÷ 1.3=4000
- 5400÷ 1.3=4153.85
- 5500÷ 1.3=4230.77
- 5600÷ 1.3=4307.69
5200 is the only option which satisfies our stated condition.
Answer:
810 boys
Step-by-step explanation:
1800 students and 55% are girls.
100%-55%=45%
1800*0.45 = 810
1800*0.55 = 990
So there are 990 girls and 810 boys.
Hope this helps :)
The <em>correct answer</em> is:
24°.
Explanation:
To find the degrees of rotational symmetry, you divide 360° by the order of symmetry.
For a regular 15-gon, the order of symmetry is 15 (there are 15 vertices that the polygon can be turned to and be mapped onto itself).
This means the degrees of symmetry would be
360/15 = 24°.
