Answer:
1. 7.6 = c
2. 45 = c
Step-by-step explanation:
1. 3^2 + 7^2 = c^2
9 + 49 = c^2
58 = c^2
square root both sides = 7.6 = c
2. 27^2 + 36^2 = c^2
729 + 1296 = c^2
2025 = c^2
square root both sides
c = 45
Answers: choice C and choice E
Plugging x = 3 and y = -1 into both equations of choice C lead to a true result (the same number on both sides). This is why the system of equations listed in choice C is one possible answer. Choice E is a similar story.
If your teacher didn't mean to make this a "select all that apply" type of problem, then it's likely your teacher may have made a typo.
Answer: the length of the base is 50 cm
Step-by-step explanation:
Formula for the area of a quarter circle: A = (pi x r^2) / 4
A = (pi x 2^2) / 4
A = (pi x 4) / 4
A = 4pi / 4
A = 1pi = 3.14 square miles
Hope this helps! :)
Answer:
y = - 3x + 5
Step-by-step explanation:
Given
6x + 2y = 10 ( subtract 6x from both sides )
2y = - 6x + 10 ( divide all terms by 2 )
y = - 3x + 5
