Since the area of a square is equal to the square of one of its side's length, then the area should be equivalent to
.
---> equation (1)
By using pythagoras rule which states that the
---> equation (2)
where the opposite side's length is 8 and the hypotenuse side's length is 10
by substituting by the values in equation (2) therefore,
substitute this value in equation (1) then
where A is the area of the square whose side is x
Money borrowed by Anthony from his friend for a sandwich and drink at lunch = $6.50
Money borrowed by Anthony from his sister to pay a library fine = $3.75
Hence, the equation to express Anthony's total debt that day will be =
Let T be the total debt , so the equations becomes,
6.50 + 3.75 = T
<span>5x²y + 2xy² + x²y
Combining like terms would be
6x²y + 2xy²
The two terms are now unique and cannot be combined any further. </span><span>

The mileage from the Supermarket to the Library may be calculated using Pythagorean Theorem.
The coordinates of the Library are (7,10) and the coordinates of the Supermarket are (3,7).
So, the distance requested is √ [ (7-3)^2 + (10 - 7)^2 = √[ 4^2 + 3^2 = √ [16 + 9] =
= √25 = 5
So, he runs 5 miles.
And the reimbursement will be $0.50 / mile * 5 mile = $ 2.50.
Answer: option B) $ 2.50
Answer:
$5.47
Step-by-step explanation:
Given data:
Annie has 4 dollar , 11 dimes, 4 pennies.
Tommy has 3 dimes, 3 pennies.
To add the money, let us first convert dime and penny into dollar.
1 dollar = $1
11 dime = $1.1
4 penny = $0.04
3 dime = $0.3
3 penny = $ 0.03
Total money = Annie’s money + Tommy’s money
= $4 + $1.1 + $ 0.04 + $0.3 + $0.03
= $5.47
So, they have $5.47 in all.
