I think the answer is 1.06666666667
For numbers 15-17, we need to remember that two of a triangle's angles are always acute and the third angle will allow us to classify the triangle based on its angles. now that we know this, let's look at #15. the first two angles listed are acute, and the third is an obtuse angle, therefore it is an obtuse triangle. on #16 we have three acute angles, so it is an acute triangle. #17 has two acute angles and a right angle so it is a right triangle.
on numbers 21-23, we need to know that a triangle with all congruent sides is called equilateral, a triangle with two equal sides is isosceles, and a triangle with no equal sides is called scalene. #21 shows two equal sides so it is an isosceles triangle. #22 has three equal sides so it is an equilateral triangle. #23 has no equal sides so it is scalene. hope this helped! :)
Answer: The minimum reliability for the second stage be 0.979.
Step-by-step explanation:
Since we have given that
Probability for the overall rocket reliable for a successful mission = 97%
Probability for the first stage = 99%
We need to find the minimum reliability for the second stage :
So, it becomes:
P(overall reliability) = P(first stage ) × P(second stage)

Hence, the minimum reliability for the second stage be 0.979.
Answer:
The length of the bottom side of the banner is 17 in.
Step-by-step explanation:
Given,
Area of the Banner = 
Height of the Banner = 24 in
Top side of the Banner = 14 in
We have to find the length of the bottom side of the banner.
Solution,
Let the length of the bottom side of the banner be 'x'.
Since the banner is in the shape of trapezoid.
So according to the formula of area of trapezoid, which is;
Area of trapezoid =
Here top and bottom sides are parallel and distance between them is equal to the height of the banner.
Now substituting the values, we get;

Hence The length of the bottom side of the banner is 17 in.
Answer:
The fraction.
Step-by-step explanation:
3
is a mixed number, so the 1 over 2 is the fraction of the whole number.
