Answer: 672
Step-by-step explanation:
You would add 293+ 379, thats the answer then you can check it by doing 672-293 to see if it = 379 which it does :D
The value of the expression ((-3)^4)^2 when simplified is 6561
<h3>What are expressions?</h3>
Expressions are mathematical statements represented by numbers, arithmetic operations and variables
<h3>How to simplify the expression?</h3>
The expression is given as:
((-3)^4)^2
Start by expanding the inner bracket
((-3)^4)^2 = ((-3)*(-3)*(-3)*(-3))^2
Next, we evaluate the product (-3)*(-3)*(-3)*(-3)
This gives
((-3)^4)^2 = (81)^2
Next, expand the exponent
((-3)^4)^2 = (81) * 81
Next, we evaluate the product
This gives
((-3)^4)^2 = 6561
Hence, the value of the expression ((-3)^4)^2 when simplified is 6561

#SPJ1
Answer:
A. She had $170.47 more in debits than in credits.
Step-by-step explanation:
In a bank account, when money is deposited, the bank credits the bank accounts while a withdrawal is debited to the account hence, if the monthly bank statement for Sierra's checking account was $402.22, and the ending balance was $231.75, the change in the account is
= $402.22 - $231.75
= $170.47
Since there was a drop in the balance comparing the beginning and ending balances, it means there were more withdrawals than deposits (in amount).
Answer:24v+24w-16
Step-by-step explanation:
8(3v+3w-2)
8 times 3 =24
So 24v+24w
Then 8 times 2=16
So the answer would be 24v+24w-16
Answer:
<em>8 more men are needed to complete the job</em>
Step-by-step explanation:
<u>Proportions</u>
This problem can be solved by step-by-step reasoning applying proportions:
- 16 men working 9 hrs a day complete the job in 14 days
- 16 men working 1 hr a day complete the job in 14*9 days
The above statement stands because the fewer hours of work, the more time the job needs to be completed. Let's continue.
- 1 man working 1 hr a day complete the job in 14*9*16 days
The same reasoning applies here, fewer men=more days.
Now for the second condition. Increase the hours/day:
- 1 man working 7 hrs a day complete the job in 14*9*16/7 days
More hours/day=less days to complete the job
- x men working 7 hrs a day complete the job in 14*9*16/(7*x) days
We know this last time is 12 days, thus:
Solving for x:
24 men are needed now, this is an increase of 24-16=8 more men
8 more men are needed to complete the job
