Answer:
3m - 25
Step-by-step explanation:
3m - 25 will represent how many minutes she practiced this week:
3m represents 3 times the number of minutes she practiced last week. Then, subtract 25 from this.
This will represent 25 minutes less than 3 times the number of minutes she practiced last week.
I believe the answer is the last one!<span />
Answer: 3
Step-by-step explanation:
Answer:
The length of PQ is <u>18</u> feet.
The length of PR is <u>18</u> feet.
The length of QR is <u>24</u> feet.
Step-by-step explanation:
A way to set an equation up for this problem is:
![\frac{4}{3}x+x+x=60](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7Dx%2Bx%2Bx%3D60)
where x is the three lengths of the isosceles triangle, but the base QR is 4/3 the length of the other two congruent sides, length PQ and PR. The 60 represents the total length of the perimeter.
Then, solve for x from the equation, and you’ll get x=18. But your not done yet. Since the variable x in the equation stands for the sides of the isosceles triangle, so plug 18 into the equation and it should look like this:
![\frac{4}{3}(18)+18+18=60](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%2818%29%2B18%2B18%3D60)
Don’t solve the whole equation, just solve the
part of the equation, which is equal to 24. So the final equation is this:
![24+18+18=60](https://tex.z-dn.net/?f=24%2B18%2B18%3D60)
Conclusion: 24 is the length of QR, and 18 is the length of PQ and PR. And they all equal 60, which is the perimeter. This is very true because the length of PQ and PR are the same (length 18), since it’s an isosceles triangle, and the length of QR is 4/3 the length of PQ and PR (4/3 of 18= 24).
Sorry for the long explanation.
But hope this helps and answers your question :)
If you swim diagonally across the rectangular pool, the distance you swim is 10 meters.
<u>Given the following data:</u>
- Width of rectangle = 6 meters
- Length of rectangle = 8 meters
To determine the distance you swim in meters, we would apply Pythagorean's theorem since the width is along the x-axis while the length is along the y-axis.
Note: The diagonal side of the rectangular pool represents the hypotenuse.
Mathematically, Pythagorean's theorem is given by the formula:
![Hypotenuse^2 = Opposite^2 + Adjacent^2](https://tex.z-dn.net/?f=Hypotenuse%5E2%20%3D%20Opposite%5E2%20%2B%20Adjacent%5E2)
Substituting the given parameters into the formula, we have;
![Hypotenuse^2 = 6^2 + 8^2\\\\Hypotenuse^2 = 36+64\\\\Hypotenuse^2 = 100\\\\Hypotenuse = \sqrt{100}](https://tex.z-dn.net/?f=Hypotenuse%5E2%20%3D%206%5E2%20%2B%208%5E2%5C%5C%5C%5CHypotenuse%5E2%20%3D%2036%2B64%5C%5C%5C%5CHypotenuse%5E2%20%3D%20100%5C%5C%5C%5CHypotenuse%20%3D%20%5Csqrt%7B100%7D)
Hypotenuse = 10 meters.
