Answer:

The answer is 3.6 acres per day

Step-by-step explanation:

To find the unit rate divide the number of acres by number of days

∴ Unit rate = $6\frac{3}{4}$ ÷ $1\frac{7}{8}$

= (6 × 4 + 3)/4 ÷ (1 × 8 + 7)/8 = 27/4 ÷ 15/8

= 27/4 × 8/15 = 18/5 = 3.6 acres per day

Please help me with question no.1 and 2. chapter ; circles

mars1129 [50]

1. Find the perimeter of the square then the circumference of the circle then subtract the circle from the square.
Area of square=length of side squared=9.8^2=96.04.
Area of circle=(pi*radius)^2=((22/7)*(9.8/2))^2

2. Area of circle=pi*r squared
38.5=((22/7)*r)^2
Solve for r
Square root of 38.5/(22/7))=r
calculate area using above formula

The table shows masses of different types of nuts that Nathan buys. He plans to mix the nuts and then separate them into bags. E

Basile [38]

Nathan can fill 10 FULL bags of mixed nuts.

To solve this problem, you must add up the total mass of ALL the nuts first.

3.64+ 2.79 = 6.43
3.44+2.73 = 6.17
6.43+ 6.17 = 12.60.

When Nathan mixes all of the nuts, it is 12.60 kg.

Since he is separating or dividing, you divide 12.60 by 1.2.

12.60 / 1.2 = 10.5

Since the question is asking FULL bags, the answer is 10.

Hope this helps! :)
