Step-by-step explanation:

1st way

Standard form: a(X-h)²+k = ( -2/3X² -16/3X -32/3) +32/3 -17/3 = -2/3(X +4)² +5

y = -2/3*X^2-16/3*X-17/3

X = -4 ±√( 15/2) = -6.7386, or -1.2614

Axis of symmetry: X= -4; Vertex (maximum)=(h,k)=( -4, 5); y-intercept is (0,-5.66666666667)

two real roots: X=-1.2613872124776866 and -6.738612787477313

A farmer market has 7/9 bushel of plums when it opens in the morning.By noon ,1/3of the plums are left .How many ,plums in bushe
FromTheMoon [43]

Answer:

farmers market sold 4/9 plums in bushel

Step-by-step explanation:

We know that at the beginning of the day we have 7/9 of a bushel of plums and that after a while there are 1/3 of a bushel of plums, so to calculate how many were sold we have to subtract the bushel of plums that were left from the initial ones

7/9 - 1/3

if we want to do this subtraction we have to find a fraction equivalent to 1/3 that can be subtracted from 7/9

1/3 = (1 * 3) / (3 * 3) = 3/9

now we are just the top and leave the denominator the same as before

7/9 - 3/9 = 4/9

Komok [63]
  • From the table showing in the diagram, Let's pick the data in the first row:

Time = 3 hours

Money earned = $45

  • The amount of money Carl earns per hour is calculated as:

3 hours = $45

1 hour = ?

Cross Multiply

1 hour x $45 / 3 hours

= $15

  • Let's confirm our answer using the data in the last column

Time = 10 hours

Money earned = $150

The amount of money Carl earns per hour is calculated as:

10 hours = $150

1 hour = ?

Cross Multiply

1 hour x $150 / 10 hours

= $15

Therefore, the amount of money Carl earns per hour is $15
