Answer:
1 1/9
Step-by-step explanation:
Answer: 25%
Step-by-step explanation: So first make the number of people who ran the marathon and the number of people who finished the marathon into a ratio
1200:4800
then make that into a fraction, 1200/4800
then make the percent of people who reached the marathon into a fraction, using 100 as the denominator and a variable as the numerator.
for example. p/100 (p, represents the percent)
then cross multiply.
1200x100=1200000
Last divide 1200000 by 4800 to get 25%.
Answer:
The zeros of the given function are -9,-1 and 12.
Step-by-step explanation:
The given function is

It is given that the x-intercept of the graph is -9, therefore -9 is a zero of the function.
Since -9 is the zero of the function, therefore (x+9) is a factor of f(x). Use synthetics method or long division method to divide the function by (x+9).




Use zero product property and quote each factor equal to 0.

Therefore zeros of the given function are -9,-1 and 12.
Step-by-step explanation:
20
opposite angles are equal
6x = 120
x = 20
Answer:
See below
Step-by-step explanation:
Find angle A by subtracting the others from 180
180 - 81 - 17 = 82
Put in order from least to greatest
Angles: B, C, A
Then the opposite sides will follow the same pattern, so they are
Sides: AC, AB, BC
