Answer:
<h2>
7°</h2>
Step by step explanation
We know that the diagonals of a square bisects it's angles and every angles of square are 90°
m<BCD = 90°
m<BCA = m< DCA = 4x + 17
m<BCA + m<DCA = m <BCD
4x + 17 + 4x + 17 = 90
4x + 4x + 17 + 17 = 90
8x + 34 = 90
8x = 90 - 34
8x = 56
X = 56/8
x = 7
Hope this helps...
Good luck on your assignment...
Answer:
temperature on the 5th days was -3 degree Celsius
Step-by-step explanation:
Mean is the average of the numbers
As per the statement:
The mean temperature for the first 4 days in January was 7°C.
Sum of the first 4 days temperature =
It is also given that:
the mean temperature for the first 5 days in January was 5°C.
then;
Sum of the first 5 days temperature =
We have to find the temperature on the 5th days.
Substitute the given values we have;
Therefore, the temperature on the 5th days was -3 degree Celsius
Hi there
We know that the formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value
PMT monthly payment
R interest rate
K compounded monthly 12 because the payment is monthly
N time
What we need from the formula above to find the monthly payment
So to find the monthly payment the formula
PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]
Another important things we need is how to find total payments and interest charge
To find total payments
Monthly payment×12
And to find interest charge
Total payments-present value
Now let's find interest charge for each credit card
Credit card A
The monthly payment is
PMT=563÷((1−(1+0.16÷12)^(
−12))÷(0.16÷12))=51.08
Total payments
51.08×12=612.96
interest charge
612.96−563=49.96
Credit card b
PMT=2,525÷((1−(1+0.21÷12)^(
−12))÷(0.21÷12))=235.11
Total payments
235.11×12=2,821.32
interest charge
2,821.32−2,525=296.32
Credit card c
PMT=972÷((1−(1+0.19÷12)^(
−12))÷(0.19÷12))=89.58
Total payments
89.58×12=1,074.96
interest charge
1,074.96−972=102.96
So total interest charge for all credit cards is
102.96+296.32+49.96
=449.24....final answer
It's c
Good luck!
