Step-by-step explanation:
Below is an attachment containing the solution.
The answer is <span>B.154/d = 44/14
</span>
<span>In a circle, the circumference (C) and diameter (D) vary directly:
C = kD
k = C/D
Circle 1: k = C1/D1
Circle 2: k = C2/D2</span>
C1/D1 = C2/D2
C1 = 154
D1 = ?
C2 = 44
D2 = 14
154/D1 = 44/14
So, the choice B. is correct.
Answer: 30°, 67° e 83°.
Step-by-step explanation: The angles are (2x + 16)/5 , x e x + 16°
Adding all the angles, comes:
(2x + 16)/5 + x + x + 16° = 180° ;
2x + 16° + 5x + 5x + 80° = 900° ;
12x = 900° - 16° - 80° ;
12x = 804°° ;
x = 804°/12 ;
x = 67°
So, the first angle is (2,67 + 16)/5 = 30°, the second is 67° and the third is 83°.
You need to find the percent of the 125 surveyed students to find the number of estimated students that like pizza.
58/125 = .464 or 46.4%
1500*.464 = 696 students like pizza.
