Answer:
It is a right triangle
Step-by-step explanation:
Information needed:
Formula: a^2+b^2= c^2
a: leg
b: leg
c: hypotenuse
the longest side is always the hypotenuse, so 17 in
the order of legs don't matter so 8 in and 15 in
Solve:
a^2+b^2= c^2
8^2+15^2= 17^2
64+225= 289
289= 289
Final answer:
It is a right triangle
The answer should be A. For example, if x = 1, and the ratio between x and y is y is 5 times greater than x, then y would equal 5, which is only true in A.
Or, use the number 5 as an example. If x = 5, and the ratio between x and y is y is 5 times greater than x, then y is 5.
And if you put that into A, y = 5x, it becomes 25 = 5(5)
Then 25 = 25, which is true!
Answer:
The answer is A.
Step-by-step explanation:
Given that Winnona took 5 tests and retake Test 5. So the mean score for this question is Total number of scores divide by Total number of tests is equals to 87 :
Let Test 5's score be x,
Let mean score be 87,

Next you have to solve the value of x :
