Answer: 10 bags
Step-by-step explanation:
First we must calculate the field area. Assuming it is a rectangle then its area equals the product of its length times its width
You use 8 pounds of fertilizer per 1,000 square feet
So the amount of fertilizer you should use is:
As the fertilizer comes in bags of 50 pound then you need
Since you can not buy 9.2 bags then we round up to the next whole number.
Finally you need 10 bags of fertilizer
Solution
To write 0.37 in expanded form using powers of ten
0.37 can be written as
0.37 = 0.30 + 0.07
Since ,
0.30 = 3/10
0.07 = 7/ 100
Therefore ,
0.37 = 3/10 + 7/ 100
= 3 x (1 / 10) + 7 x (1 / 100)
Hence , option C
#1
5x + 10 + 13x -10 = 180
18x = 180
x = 180/18
x =10
answer: value of x = 10
#2
21x +5 +37x +1 = 180
58x + 6 = 180
58x = 180 -6
58x = 174
x = 174/58
x = 3
so 37x + 1
= 37(3) + 1
=111 + 1
=112
answer: measure of the highlight angel = 112
Answer:
(a) 1
(b) 1
(c) 3.03
Step-by-step explanation:
The given quadratic equation is
Subtract 27 from both sides.
Taking out common factor.
Divide both sides by 4.
If an expression is , then we need to add , to make it perfect square.
Here, b=2, so
Add 1 on both sides.
Taking square root on both sides.
Subtract 1 from both sides.
and
and
Only one solution is positive.
Greatest solution is 3.031, therefore the approximate value of this solution is 3.03.
