Answer:
We have the same homework!!!!
hours that passed= 10
Step-by-step explanation:
(1st step)We start with the expression:
(1st)82-0.4x=78
"STARTED at 82 degrees" 82
"Cooling DOWN 0.4 degrees" -0.4
"EACH hour" x
"NOW 78 degrees" =78
(2nd step) We want to get the variable x alone, so we have to do the opposite sign they have, to cancel the number out for it to be 0.
(1st) 82 -0.4x =78
(2nd) -82 ÷-0.4 =78
(3rd)Now, you work out the problem (transfer the numbers from the left to the right). First, you have to do the subtraction sign, not sure why.
(1st) 82 -0.4x =78
(2nd) -82 ÷-0.4 =78
(3rd) 78 -82= -4
-4÷-0.4= 10
X= 10
there you have it!
To make sure this is correct, you do the following.
82 -0.4 x 10
Solve using PEMDAS
-0.4 x 10 = -4
its time to add 82.
82 - 4 = 78
78 is the exact temperature that was said in the problem
Answer:
Step-by-step explanation:
By proportion it will be (5/3) * 12
= 60/3
= 20 days.
Answer:
The answer is that she would pay $65.56 in finance charges at the end of the month.
Step-by-step explanation:
Given: APR = 19.99%
Carry Over Balance: $398.97
The APR or Annual Percentage Rate, is calculated daily. You will need to get the daily periodic rate, or DPR, so divide the APR by 365:
19.99% = .1999
.1999 / 365 = .005477 (This is the Approximate DPR, rounded up to .005477)
To get the finance charge, multiply the average daily balance by the DPR and then by 30 days:
398.97 * .005477 * 30 = $65.56 finance charge for this carry over balance, at the end of the month. This assumes that the balance is the average daily balance.
Hope this helps!! Have a great day!
Answer:
74.5°
Step-by-step explanation:
Hannah, the kite and Patricia form the vertices of a right-angled triangle with the hypotenuse side the length of the string L = 60 feet and adjacent side the distance between Hannah and Patricia = d = 16 feet.
Let the angle between the string and the sand be Ф.
By trigonometric ratios,
cosФ = adjacent/hypotenuse
= d/L
= 16 feet/60 feet
= 0.2667
Ф = cos⁻¹(0.2667)
= 74.53°
≅ 74.5°
So, he angle between the string and the sand is Ф = 74.5°
