Step-by-step explanation:
The school bought 16 calculators
Answer:
A/C
Step-by-step explanation:
Since the sum of the angles in a triangle equals 180°, and angle C is 90°.
That means angles A and B add up to 90°, that is, they are complementary angles. Therefore the cosine of B equals the sine of A.
We saw on the last page that sin A was the opposite side over the hypotenuse, that is, a/c. Hence, cos B equals a/c.

Answer: John's situation
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each situation.
John’s situation:
The amount of money that John has (y) is equal to his school account (40) minus the product of the number of days (x) and the amount he spends per day( 3)
y =40-3x
As days pass by, John has less money (negative rate of change)
Judy's situation
The amount of money that Judy has in her savings account (y) is equal to the product of the number of days (x) and the amount he saves per day (20/2)
y = x (20/2)
Answer:
21 7/8 square feet
Step-by-step explanation:
To solve the above Question, we have to used the formula of a parallelogram
The formula is given as:
Base × Height
Base = 6 1/4 feet
Height = 3 1/2 feet
Area = 6 1/4 × 3 1/2
Area = 25/4 × 7/2
Area = 175/8
Area = 21 7/8 ft²
Therefore, they would need 21 7/8 square feet poster paper for the parallelogram shaped banner
