Answer: The sum of 75.2+(57.376+24.8) is 157.376.
Explanation:
The commutative property of addition states that,
The associative property of addition states that,
The given expression is 75.2+(57.376+24.8).
First use commutative property of addition in the parenthesis.
Now use associative property of addition.
Now simplify the expression,
Therefore, the sum of 75.2+(57.376+24.8) is 157.376.
Answer:
Part A: yes
Part B: yes
Part C: yes
Step-by-step explanation:
Part A:
77² + 420² = 427²
5,929 + 176,400 = 182,329
182,329 = 182,329
---------------------------------------------------------
Part B:
279² + 440² = 521²
77,841 + 193,600 = 271,441
271,441 = 271,441
----------------------------------------------------------
Part C:
39² + 760² = 761²
1,521 + 577,600 = 579,121
579121 = 579,121
----------------------------------------------------------
To solve this question you would first multiply all the dimensions of the pillar together. That would be:
2.5 x 2.5 x 12 = 75 square feet
Then you take the weight of the pillar and divide it by the amount of square feet:
12,000 / 75 = 160 pounds per square foot.
Answer:
41 over 24
Step-by-step explanation:
7 2/3 can be "translated" into 3 times 7 plus 2 which is 22, so now it's 22 over 3.
5 5/8 can be "translated" into 8 times 5 plus five is forty five, so now it's 45 over 8.
We now need a common denominator.
Multiples of 8: 8, 16, 24, 32
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24
24 are both multiples of 8 and 3.
Now you have to multiply 22 and 8 because 3 times 8 equals 24 and so you have to do it to the numerator.
22*8=176
Now you have to multiply 45 and 3 since 8 times 3 equals 24 and so you have to do it to the numerator, too.
45*3=135
All you have to do now is subtract 176 from 135 which is 41
