Answer:40 miles per hour
Step-by-step explanation:
This is because, If 20 miles is 1/2 of his drive home then 40 miles should be the rest. Multiply 20 by 2 since it is 1/2
Suppose the original price to be x.
62%x=296.4
Divide both sides by 62% to get x=478, which is the original price.
Answer:
After one year Kenny will have $520.
Step-by-step explanation:
Flip the second fraction and change the fraction into multiplication
Also, change 2 1/2 into a improper fraction
2 1/2 = 5/2
(5/2)/(5/8) becomes 5/2 x 8/5
Multiply across
5 x 8 = 40
------- -----
2 x 5 = 10
Simplify 40/10
40/10 = 4
4 is your answer
hope this helps
Answer:
z=4 and z=-1/3 are the zero's
Step-by-step explanation:
To find the zeros of the quadratic function, we need to set it equal to zero.
f(z)=3z^2−11z−4
0 =3z^2−11z−4
Now we need to factor the function
0 = (z - 4) (3 z + 1)
Then using the zero product property set each factor to zero
0 = z-4 0 = 3z+1
Now solve
0+4 = z-4+4 0 -1 = 3z+1-1
4 =z -1 = 3z
-1/3 = 3z/3
-1/3 =z
