Answer:
2x + 4y = 14 = x= −2y+7
3x - 4y = -39= x= 4=3
y−13
Step-by-step explanation:
Answer: question 5 is C
Question 4 is 37.68
Question 3 is 153.86 ft sq
The question about finding the area with a diameter of 16mm is 803.84
The next one is A. 25÷8
Step-by-step explanation:
C = 2 pi r
C = 2 pi (7.8) and you get 49.01
Becuse the question is asking to round c is the best choice
When using the formula of C = 2 pi r, since radius is half of the diameter, 12÷2=6
The formula for this one is A = pi r sq
You have the radius for this one is 7
Put 7 into that and you get. ~153.94
Answer:
Step-by-step explanation:
The x difference:
8 - 1 = 7
The y difference:
-4 - -7 = 3
Distance:
7² + 3² = 58
√58 ≅ 7.62

Answer:
Step-by-step explanation: Round to the nearest whole number. In order to find the standard deviation, we first have to calculate the mean (average) of the numbers. To get this we add all the numbers together and then divide by 12 since there are 12 numbers. The mean = 782. Next, we take each number and subtract the mean, taking the result and squaring it.
