The formula for the area of a square is A = s^2, where s is the side length. Here, 225 cm^2 = s^2.
To find the side length, we need only take the sqrt of both sides of this equation and eliminate the negative root:
plus or minus √{225 cm^2) = s. Thus, s = 15 cm = side length.
Answer:
Step-by-step explanation:
A 180 degree rotation around the origin would be the same things as a reflection across the x-axis followed by a reflection across the y-axis.
This would result in the new location being (-3, -2) The x coordinate is -3.
Answer:
She sold 5.775 kilograms of pears at the farmer's market.
Step-by-step explanation:
Let's first determine the information that the question gives us, and what we need to find.
Given:
The farmer sold 7.7 kilograms of apples and pears
1/4 of the weight is apples
The rest of the weight is pears
Find:
Kilograms of pears that the farmer sold
Start by finding the fraction of the whole weight that was pears...
![1-\frac{1}{4}=\frac{4}{4}-\frac{1}{4}=\frac{3}{4}](https://tex.z-dn.net/?f=1-%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7B4%7D%7B4%7D-%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7B3%7D%7B4%7D)
Now, find 3/4 of 7.7...
![\frac{3}{4}(7.7)=\frac{23.1}{4}=5.775\ kg](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%287.7%29%3D%5Cfrac%7B23.1%7D%7B4%7D%3D5.775%5C%20kg)
She sold 5.775 kilograms of pears at the farmer's market.
The answer is (3,6) x=3 y=6
