Answer:
122°
Step-by-step explanation:
The formula for finding the sum of all angles in a polygon is:
(n-2) * 180°
n is the number of angles
Here n = 7, so the sum of all angles is
(7-2) * 180° = 900°
x = 900 - 128 - 130 - 120 - 115 - 145 - 140 = 122°
Make me the brainliest ;)
Steps:
1. Do a proportion
8000 pounds/4 tons= 7000 pounds/ x
2. Do 7,000 times 4 which equals 28,000
3. Do 28,000 divided by 8,000
4. Your answer is
3.5 tons
Answer:
B. 520
Step-by-step explanation:
Partial quotient is simply the method used to find the value of a quotient by dividing bits by bits until you get to the answer. For instance if you want to divide 124/4
Whatever closest multiple of 4 to 124 you remember, write it down. For instance I remember 80 first.
80 is the 20th multiple of 4 (80÷4 = 20).
Then subtract the number from the original number you want to divide
124 – 80 = 44
Again, write down the closest multiple of 44 you remember. To me is 40, and it is the 10th multiple.
Subtract 40 from 44 you have 4 left.
It's now easy to divide 4 by 4 which is 1.
To now get the quotient in total, you'll add up
20 + 10 + 1 = 31.
Therefore, to use partial quotient in this problem, the best choice to begin with will be 520 because it is the 20th multiple of 26. Although 780 is the 30th multiple of 26, 520 will be easier to remember. For this reason, it is the best choice.
