The percentage of correct answers is 85% and the percentage of incorrect answers is 15% and this can be determined by using the unitary method.
Given :
- Henry takes a math test that had 20 questions.
- He answered 17 questions correctly and 3 questions incorrectly.
The following steps can be used in order to determine the percentage of correct and incorrect questions Henry answered:
Step 1 - The unitary method can be used in order to determine the percentage of correct and incorrect questions Henry answered.
Step 2 - The total number of questions in a math test is 20. The total number of correct answers is 17 and the total number of incorrect answers is 3.
Step 3 - If the 20 is the 100% questions then the percentage of 17 correct answers is:
= 85%
Step 4 - If the 20 is the 100% questions then the percentage of 3 incorrect answers is:
= 15%

Answer:
AB = 4.41
Step-by-step explanation:
cos theta = opposite / hypotenuse
We know theta = 25 and the opposite side =4
cos 25 = 4 / hypotenuse
Multiply each side by hypotenuse
hypotenuse * cos 25 = 4/ hypotenuse * hypotenuse
hypotenuse * cos 25 = 4
Divide each side by cos 25
hypotenuse * cos 25/ cos 25 = 4/cos 25
hypotenuse = 4/cos 25
hypotenuse = 4.413511676
Round to the nearest hundredth
hypotenuse = 4.41

Answer:
110sin(72°) feet
Step-by-step explanation:
In the right triangle with the 110 ft ladder as the hypotenuse, the side opposite the 72° angle represents the maximum height the ladder will reach. The definition of the sine function tells you ...
Sin = Opposite/Hypotenuse
so the Opposite side will be ...
ladder height = (110 ft)sin(72°)
