Split the shape into 2 rectangles so
the dimensions of the rectangles are 3 by 6 and 6 by 9 so
3(6)+6(9) so
18+54=
C) 72 square yards
Answer:
- False
- False
- True
Step-by-step explanation:
Since the given expression represents the account balance, the initial amount (when x=0) is $500 in Account A, and $100 in Account B. (Less money was invested in account B.)
The growth rate of each account is $1.03 per year.* (The growth rate ($/year) is identical for each account.)
The total of the initial amounts invested is $500 +100 = $600.
_____
<em>* Comment on growth rate</em>
Since the account balance is shown as <em>greater than</em> or equal to the given expression, there appears to be the possibility that adjustments are made to the account balance by some means other than the growth predicted by this inequality. For example, if the balance in Account A is $900 at the end of 1 year, the inequality will still be true, but the extra $398.97 will be in addition to the $1.03 growth predicted by this expression.
This means <em>we really cannot say what the growth rates of the accounts might be</em>, except that it is a minimum of $1.03 per year in each account.
_____
<em>Comment on the expressions</em>
More usually, we would expect to see an account balance have the equation a = 400·1.03^x. That is, the interest rate would be 3% and it would be compounded annually. The expression 400 + 1.03x is very unusual in this situation.
let those numbers be x and y
According to your question
x + y = -7
x - y =14
adding both equations
2x = 7
or x = 7/2
substitute value of x in either equation
y = -21/2
So,
x= 7/2
y=-21/2
Hope this helps!

Answer:
Step-by-step explanation:
<u>1. Cell phone usage</u>
Mon to Sun = 38, 62, 40, 10, 30, 55, 65
- Mean = (38+62+40+10+30+ 55 + 65)/7 = 43 minutes rounded
<u>2. Water bills</u>
Jan to Dec = $40 $42 $40 $38 $48 $50 $58 $62 $56 $46 $44 $44
- Mean = (40+42+40+38+48+50+58+62+56+46+44+44)/12 = $47 rounded
Answer: 53%
Step-by-step explanation: First this problem we will use the "Percent Error" equation to solve.
difference = percent error x actual
First, subtract the values 8 - 17, which equals -9, but find the absolute value of -9, which is 9. Lets plug in 9 to the equation. 17 belongs in the "actual category" since 8 was to 17.
9 = percent error x 17
9/17 = percent error
About 0.53 = percent error
Now, to get your percent, multiply 0.53 x 100, which equals 53.
So the percent error from 8 to 17 is 53%
