The number bushels they get from 15 acres of land is 2550
<em><u>Solution:</u></em>
Given that, farmer gets 340 bushels of corn from 2 acres of land
To find: Number bushels they get from 15 acres
Let us first find the unit rate, that is we have to find number of bushels from 1 acre of land
From given question,
2 acres of land = 340 bushels of corn
Therefore, for 1 acres of land,
<em><u>How many bushels can they get from 15 acres?</u></em>
So, multiply the number of bushels from 1 acre of land by 15 to get answer
Thus number bushels they get from 15 acres of land is 2550
Answer:
The radius is <u>10 feet</u>.
Step-by-step explanation:
The diameter is always twice as large as the radius so divide the diameter by 2 and you'll get the radius.
20 ÷ 2 = 10
Hope this helps! :D
I think there are two solutions, 63 or 147:
63 = 3² x 7, factors 1 | 3 | 7 | 9 | 21 | 63<span>
147 = 3 x 7</span>², factors 1 | 3 | 7 | 21 | 49 | 147
Answer:
x < -4 or x > 7.
Step-by-step explanation:
We first determine the critical points by solving x^2 - 3x - 28 = 0:
x^2 - 3x - 28 = 0
(x - 7)(x + 4) = 0
x = 7, - 4
so the critical points are -4 and 7.
Create a Table (pos = positive and neg = negative):
Value of x< - 4 -4 < x < 7 x > 7
---------------------|----------- |--------------------- |---------------------
x + 4 NEG POS POS
x - 7 NEG NEG POS
(x + 4)(x - 7) POS NEG POS
So the function is positive (>0) for x < -4 or x > 7.
You can also do this by drawing the graph of the function.
