33 c = 91.4 Fahrenheit
62 c =143.6 f
-25 c= -13 f
89c= 192.2 f
212c = 413.6 f
Answer:
Step-by-step explanation:
<h3>What are the definitions?</h3>
- Obtuse triangle - the triangle with angle greater than 90°;
- Acute triangle - the triangle with all interior angles under 90°;
- Isosceles triangle - the triangle with a pair of equal sides;
- Scalene triangle - the triangle with all three sides (or angles) of different measure.
<h3>What we have?</h3>
- All sides are different and all angles are under 90°.
<h3>Which option is correct?</h3>
If QR is a median, then:
![\dfrac{NO+MP}{2}=QR](https://tex.z-dn.net/?f=%5Cdfrac%7BNO%2BMP%7D%7B2%7D%3DQR)
We have NO = 30, MP = 9x - 42 and QR = x + 15. Substitute:
![\dfrac{30+9x-42}{2}=x+15\qquad\text{multiply both sides by 2}\\\\9x-12=2x+30\qquad\text{add 12 to both sides}\\\\9x=2x+42\qquad\text{subtract 2x from both sides}\\\\7x=42\qquad\text{divide both sides by 7}\\\\\boxed{x=6}](https://tex.z-dn.net/?f=%5Cdfrac%7B30%2B9x-42%7D%7B2%7D%3Dx%2B15%5Cqquad%5Ctext%7Bmultiply%20both%20sides%20by%202%7D%5C%5C%5C%5C9x-12%3D2x%2B30%5Cqquad%5Ctext%7Badd%2012%20to%20both%20sides%7D%5C%5C%5C%5C9x%3D2x%2B42%5Cqquad%5Ctext%7Bsubtract%202x%20from%20both%20sides%7D%5C%5C%5C%5C7x%3D42%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%207%7D%5C%5C%5C%5C%5Cboxed%7Bx%3D6%7D)
<h3>Answer: A. 6</h3>
Answer:
A, (13/3 x 5/13)
Step-by-step explanation:
So first, you should change the mixed numbers into improper fractions. To convert, just multiply the whole number by the denominator and add the numerator. Do that to both fractions and you should get 13/3 ÷ 13/5. Since you need to switch to multiplication, switch the sign and flip that fraction/ That asnwer is 13/3 x 5/13. Hope that helps! :)
As per the Intersecting Chords theorem, if two chords cross in a circle, the products of the chord segments' measures are equal. The measure of the line segment is DF is 14 units.
<h3>What is Intersecting Chords theorem?</h3>
If two chords cross in a circle, the products of the chord segments' measures are equal.
As per the Intersecting Chords theorem, the product of DF and FB will be equal to the product of CF and FA, therefore,
DF×FB = CF×FA
(x+8) × 8 = 16 × 7
(x+8) = (16×7)/8
(x+8) = 14
Hence, the measure of the line segment is DF is 14 units.
