Answer:
y = 28x
Step-by-step explanation:
To find the answer, we need to divide the number of bushels by the number of acres. If the quotient is the same for all three divisions, then the quotient is how many times x is multiplied to get y.
140 / 5 = 28
224 / 8 = 28
420 / 15 = 28
Therefore, y = 28x is our answer.
In this question, each star equal to 4 students. If the people on 85 and 90 take the test again that means their number should be 14+4 people= 18 people.
If they all get 95, then it means we need to add 18 people to the 95 graph. The number of stars would be: 18 people / (4people/stars)= 4.5 stars
If you add the stars graph it will be easier. It should be clear that 85 will have 1 stars and 90 have 3.5 stars. Adding them up will be 1 stars + 3.5 stars= 4.5 stars
Answer: 56 7/20 ft²
Step-by-step explanation: Let's transform the width and the lenght in improper fractions:
w = 5 3/4 ft, = 4*5+3/4 = 23/4 ft
l = 9 4/5 ft = 5*9+4/5 = 49/5 ft
Area = w * l
A = 23/4 * 49/5 = 1127/20 ft²
1127/20 ⇒ 56 7/20 ft²
