Answer:
I would say the last one looks like its the best
Step-by-step explanation:
Because it seems to go to left 1 unit and up 2 units
The radius going through the tangent point is perpendicular to the tangent line, so ΔQRT is a right triangle.
QT²=QR²+RT²
QR and QS are both radii, so QR=QS=15
QT²=15²+36²
QT=39
Answer: the test has 10 multiple-choice questions and 15 Word problems questions.
Step-by-step explanation:
Let x represent the number of multiple-choice questions in the test.
Let y represent the number of Word problems questions in the test.
The total number of multiple-choice and Word problems questions in the test is 25. This means that
x + y = 25
The multiple-choice questions are worth three points and Word problems are worth four points. The test is worth a total of 90 points. This means that
3x + 4y = 90 - - - - - - - - - - -1
Substituting x = 25 - y into equation 1, it becomes
3(25 - y) + 4y = 90
75 - 3y + 4y = 90
- 3y + 4y = 90 - 75
y = 15
x = 25 - y = 25 - 15
x = 10
