For some integer k, you have
.. n = 7k +2
Then, multiplying by 4, you have
.. 4n = 28k +8
.. 4n = 7(4k +1) +1

The remainder is a) 1.

N:7=x remainder 2
⇒ n= 7*x +2

4n= 4*(7x+2)=28x+8=28x+7+1=7*(4x+1)+1
⇒ the remainder is 1

Find the given angle measure for regular hexagon ABCDEF.

stepan [7]

Answer:

Question 12: 60°

Question 13: 30°

Question 14: 60°

Question 15: 120°

Step-by-step explanation:

Question 12: The measure of a circle is 360°, so ∠CGD which is $\frac{1}{6}$ of a full rotation is 60°.

Question 13: ∠CGH is $\frac{1}{2}$ of ∠CGD, so its angle measure is 30°.

Question 14: Since the interior sum of all angles in a triangle is 180° and two angles have measures of 90° and 30°, that means ∠HCG has a measure of 60°.

Question 15: Since ∠EGC is $\frac{1}{3}$ of a full rotation, and is twice as great as ∠CGD, that means it has an angle measure of 120°.

Help pls I'm so confused with this

Answer:

6400 AED

9.14%

yes. The interest rate is 9.14%. This is less than 10%

Step-by-step explanation:

Interest amount she would pay = total of loan to be repaid - amount borrowed

16,400 - 10,000 = 6,400 AED

Interest = loan x interest rate x time

we have all the parameters of the above equation apart from the interest rate. We can thus determine the interest rate from the above equation

6,400 AED = 10,000 x interest rate x 7

6,400 AED = 70,000 x interest rate

Divide both sides by 70,000 to find a value for interest rate

interest rate = 0.091429 = 9.14%
