The farmer owned 100 acres of land. A year later he bought more property and then owned 140 acres. Is this a percent increase or decrease? Find the % change. Round to the nearest whole percent, if necessary.
Answer:
The percentage change (an increase) wa 40%.
Step-by-step explanation:
The beginning number of acres was 100; adding 40 more brought that to 140 acres. This was an increase. Dividing the increase (40) by the starting value (100) yields 0.40. Finally, multiplying this result by 100% yields 40%.
The percentage change (an increase) wa 40%.

1÷2(2x+6)=4x-1
solve pls no links!!!
Answer:
Step-by-step explanation:
1 ÷ 2(2x+6) = 4x-1
[tex]\frac{1}{2(2x + 6)} = 4x -1[/tex]
[tex]\frac{1}{2*2x+2*6 } = 4x - 1 \\\\\frac{1}{4x + 12} = 4x - 1\\[/tex]
1 = (4x - 1)(4x + 12)
Use FOIL method.
1 = 4x * 4x + 4x *12 - 1 * 4x - 1*12
1 = 16x² + 48x - 4x - 12
1 = 16x² + 44x -12
0 = 16x² + 44x - 12 -1
16x² + 44x - 13 = 0

PART C:
What fraction of the flowers are white?
A) 7/24 B) 1/3 C) 3/8 D) 7/11

Part-C
fraction of flowers that are white
[tex]\Rightarrow 1-\dfrac{3}{8}-\dfrac{1}{3}\\\\\Rightarrow 1-\dfrac{9+8}{24}\\\\\Rightarrow 1-\dfrac{17}{24}=\dfrac{7}{24}[/tex]
a woodworker makes wooden checkerboards. identify any zeros of the function, and interpret what the zeros mean in terms of the situation
I have attached an image showing the graph of the function.
Answer:
Zeros are x = $15 and x = $70 and they are the prices at which the woodworker will neither loss nor gain money.
Step-by-step explanation:
First of all, the zeros of a function f(x) are defined as the values of x where f(x) = 0. That is the points where the graph curve touches the x-axis.
Now, from the attached graph, when we locate the point that the curve touches the x-axis, it's at x = 15 and at x = 70.
This means that f(x) = 0 at x = 15 and at x = 70.
Now, from the graph; f(x) is the profit function. So when f(x) = 0, it means there is zero profit which implies no gain and no loss.
Thus, we can conclude that the prices at which the woodworker will neither loss nor gain money is when the price is; x = $15 and x = $70

1⁵ + 5² / 25⁰ - 5¹=
Answer: 6.5
Step-by-step explanation:
1 (to the power of 5) is 1 and 5 (to the power of 2) is 25.
25 (to the power of 0) is 1 and 5 (to the power of 1) is 5.
1 + 25 = 26 and 1 - 5 = -4.
Since the slash means division in math and any number to the power of 0 is always 1.
The answer would be: -6.5.
The solution for the expression [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex] after simplifying is,
[tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)} = \frac{- 13}{2}[/tex]
We have to give that,
The expression to simplify is,
⇒ [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex]
Simplify the expression by simplifying each term in a given fraction,
⇒ [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex]
Since,
1⁵ = 1
5² = 5 × 5
= 25
25⁰ = 25
5¹ = 5
Substitute all the values,
⇒ [tex]\frac{(1 + 25)}{(1 - 5)}[/tex]
⇒ [tex]\frac{26}{-4}[/tex]
⇒ [tex]\frac{-26}{4}[/tex]
Simplify the fraction in simplest form,
⇒ [tex]\frac{- 13}{2}[/tex]
Hence, The solution is, - 13/2

Sub Answer
acer
Answer:
£290.70
Step-by-step explanation:
Number of notes of $50 = 5
Total value = 50 × 5 = $250
Number of notes of $20 = 2
Total value = 20 × 2 = $40
Number of notes of $10 = 7
Total value = 10 × 7 = $70
Number of notes of $5 = 3
Total value = 5 × 3 = $15
Total value of all notes with John = 250 + 40 + 70 + 15
= $375
Since, $1.29 = £1
Therefore, $1 = £[tex]\frac{1}{1.29}[/tex]
Therefore, $375 = £ [tex]\frac{375}{1.29}[/tex]
= £290.70
