Answer:
The wide of the city is 10.7km
Step-by-step explanation:
To solve this we first have to know the formula to calculate the area of a square
a = area = 115 km²
s = side
a = s * s
now we replace with the known values
115 km² = s * s
115 km² = s²
√(115 km²) = s
10.724km = s
Round to the nearest tenth
s = 10.724km = 10.7km
The wide of the city is 10.7km
Y= 3/4x - 7/4
Hope this helps
Answer:
21.69% decrease.
Step-by-step explanation:
So we want to find the percentage change from 16.6 to 13.
First, since 13 is smaller than 16.6, we know that this is decrease.
The formula for percentage change is given by:
The new value is 13. The old value is 16.6. Put these into the equation:
Simplify the numerator. 13-16.6 is -3.6. Thus:
Multiply both the numerator and denominator by 10:
Reduce the fraction:
Use a calculator. Approximate:
We ignore the negative because the negative simply tells us that it's decreasing (on a side note, if the answer is positive, it's a percent increase). So, the percent change is an approximate 21.69% decrease.
