1. A)
7x= 3(35)
7x= 105
105/7= 15
Therefore x=15
2. C)
Answer:
To convert centimeters to meters, multiply the centimeter value by 0.01 or divide by 100. For example, to find out how many meters there are in 10 centimeters, multiply 10 by 0.01, that makes 0.1 meter in 10 cm. What is a Centimeter? Centimeter (centimetre) is a metric system length unit. 1 cm = 0.01 m.
Step-by-step explanation:
Answer:
30 degrees
Step-by-step explanation:
USE the sine function to determine S. Set up the equation:
sine(S) = 1/2 -->
S = Sine^-1(1/2) -->
S = 30 degrees
Exam + Tests + Quizzes + HW + Projects = 90
Exam = 10% * grade (x) = 0.1 * x
Tests = 50% * 85 = 0.5 * 85 = 42.5
Quizzes = 15% * 95 = 0.15 * 95 = 14.25
HW = 15% * 98 = 0.15 * 98 = 14.7
Projects = 10% * 92 = 0.1 * 92 = 9.2
Exam + Tests + Quizzes + HW + Projects = 90
(0.1 * x) + 42.5 + 14.25 + 14.7 + 9.2 = 90
(0.1 * x) + 80.65 = 90 (subtract 80.65 from each side)
(0.1 * x) = 9.35 (divide 0.1 from each side)
(0.1 * x)/0.1 = 9.35/0.1
x = 0.935
The answer is 93.5%
