Answer:
Step-by-step explanation:
Given equation to us is ,
So , a equation is said to be a quadratic equation if the highest degree of the variable is 2 . On simplifying the Equation ,
Taking x as LCM ,
Transposing x to RHS .
Putting all terms in LHS
Since here the highest degree of the variable is 3 not 2 . So its a cubic equation and not a quadratic equation .

Answer:
I believe (not confident) You take 180-28 and divide that by 2. (76 degrees)
We know that the top angle of the triangle is 28 degrees because vertical angles are congruent.

Answer: 2598.8
Solution:
Step one: 49•12.80 = 627.2 (the amount that people under 16 payed)
Step two: 155-49=106 (the amount of people over 16)
Step three: 106•18.60=1971.6 (the amount of money that people over 16 payed)
Step four: 627.2+1971.6=2598.8 (the total amount of collected money from tickets)
Answer:
-23/18
Step-by-step explanation:
-7/9 = -70/90
-5/10 = -45/90
-70-45 = -115
-115/90
-23/18
EDIT: whoops, I subtracted 45 from 70 instead of adding them. it should be correct now.
hope this helps, goodluck with your schoolwork/homework.
sorry for any errors or bad explanations.
Answer:
66 cm (Option B)
Step-by-step explanation:
The formula for the circumference of a circle is C = 2πr, so plug the values into the formula. The radius, (r) of a circle is one half of the diameter, so split 21 is half to get a radius of 10.5. Use 3.14 for π.
C = 2πr
C = 2(3.14)(10.5)
C = 6.28 × 10.5
C = 65.94
Rounded to the nearest unit, you get a answer of 66 cm.
Hope this helps! :)
