Answer:
y = 2
Step-by-step explanation:
y varies inversely with x setup is:
y = k/x
7 =
(find 'k')
k = 7/1 · 2/3
k = 14/3
use what you know about 'k' and 'x' to solve for 'y'
y = 14/3 ÷ 7/3 (remember to multiply by the reciprocal when dividing fractions)
y = 14/3 · 3/7
y = 2
Answer:
3rd choice
Step-by-step explanation:
In division for variables with same base, you do subtract top exponent minus bottom exponent. She did that correctly since -3-(-1)=-3+1=-2 and -2-1=-3.
The problem said m=-2 and n=4 and she replace m with (-2) and n with (4). She did this correctly.
You can multiply base numbers unless the exponents are the same 4 doesn't have the exponent -2 on it so you can't do (4(-2))^(-2)
The error is the 3rd option.
Length to width is : 20:15 which reduces to 4:3 or 4/3 or 4 to 3
3230 kilograms of the soil supplement are required for the entire vineyard
<h3>Further explanation</h3>
Some units that need to be recalled are as follows :
<em>1 km = 1000 m = 10³ m</em>
<em>1 km² = 1000000 m² = 10⁶ m</em>
<em>1 km² = 247 acres</em>
<em>1 kg = 1000 g</em>
Let's tackle the problem now!
A vineyard has 145 acres of Chardonnay grapes.



A particular soil supplement requires 5.50 grams for every square meter of vineyard.







<h2>Conclusion :</h2>
It required 797500/247 kg ≈ 3230 kg of the soil supplement for the entire vineyard
