Answer:
c. Cindy needs to change the number of payments to 17 to include the down payment.
Step-by-step explanation:
Let us see the options one by one.
a. Cindy needs to change the monthly payment amount to $250 as agreed.
As she has written the amount as $225 so she will be asked to change it.
b. Cindy needs to include the word “monthly” to describe the frequency of her payment.
As Cindy has not mentioned the frequency of payments, she may be asked to add the word monthly.
c. Cindy needs to change the number of payments to 17 to include the down payment.
Cindy will not be asked to change the number of payments as the installments are counted separate from the down payment.
d. Cindy needs to include Robert’s last name and her full name.
Full names are used in legal documents so she may be asked to add their full names in the legal contract.
Hence, option C is correct ..
Answer:
The diagonal must be 17 ft
Step-by-step explanation:
To determine the diagonal, we will use the Pythagorean theorem. That is for right triangles (which means the angle is 90 degrees)
a^2 + b^2 =c^2
where a and b are the legs and c is the hypotenuse
a = 8 ft and b = 15 ft because these are the sides of the wall and the hypotenuse will be the diagonal
8^2 + 15^2 = c^2
64+225 = c^2
289 = c^2
Take the square root of each side
sqrt(289) = sqrt(c^2)
17 =c
The diagonal must be 17 ft
Answer:
Step-by-step explanation:
To operate between mixed numbers is always better to write then in fraction form first (as improper fractions), and then operate using the rules to combine fractions.
For the first mixed number :
For the second mixed number:
So now we have to subtract these two fractions, so we need to write them with the same common denominator (6 x 5 = 30):
and finally we write the obtained answer in mixed number form:
Answer:
Part a) The measure of the sum of all angles in a regular dodecagon is equal to 1,800 degrees
Part b) The measure of one of its interiors angles is 150 degrees
Part c) The measure of one of its exterior angles is 30 degrees
Step-by-step explanation:
Part a) What is the measure of the sum of all angles in a regular dodecagon (12 sides)
we know that
The formula to calculate the sum of the interior angles in a regular polygon is equal to
where
n is the number of sides of regular polygon
In this problem a regular dodecagon has n=12 sides
substitute
Part b) What is the measure of one of its interiors angles?
To find out the measure of one of its interior angles, divide the sum of all angles by the number of sides
Part c) What is the measure of one of its exterior angles?
we know that
The sum of one interior angle and its corresponding exterior angle must be equal to 180 degrees
Let
x ---> the measure of one exterior angle
solve for x
