Answer:

For the first part of 4 questions wrong: he would get 42 points

For the second part 48 points

Step-by-step explanation:

For the first part of 4 questions wrong: he would get 42 points because 50 divided by 2 is 25 and 25 minus 4 is 21 and 21 times 2 is 42.

For the last part I'm guessing x = 1 so again 50 divided by 2 is 25 and 25 minus 1 is 24 and 24 times 2 is 48

I think it is right.

What is the value of x in the figure? Enter your answer in the box. x = Three lines creating six angles with the top left angle
Semmy [17]

Three lines creating six angles

3 angles on top, 3 angles below


Since the top left angle is a right angle

It means the line that divides the top angles from the angles below is bisected by a perpendicular line.


This means the sum of the angles of the top left = 90°

Therefore, x + 61° = 90°

x = 90° – 61°

x = 29°

KiRa [710]

Answer:

Step-by-step explanation:

Notes payable = $348000

Payable interest = Note payable × Interest rate × (no of months used/no of months in a year)

348000*(8/100)*(3/12)

= 3480*8*(3/12)

= 83520/12

= $6,960

The total cash will be $348000 + $6960 = $354960

Therefore in the account statement, om the debit side we will have the Notes payable and payable interest, while on the credit side we will have total cash.

This can be seen as attached.
