Answer: 20 hr
Step-by-step explanation:
Given
The depth of accumulated snow is ![d=10\ in.](https://tex.z-dn.net/?f=d%3D10%5C%20in.)
Snow is melting at the rate of ![r=0.5\ \text{in. per hour}](https://tex.z-dn.net/?f=r%3D0.5%5C%20%5Ctext%7Bin.%20per%20hour%7D)
Time taken for complete melting of snow is
![\Rightarrow t=\frac{d}{r}\\\\\Rightarrow t=\frac{10}{0.5}=20\ hr](https://tex.z-dn.net/?f=%5CRightarrow%20t%3D%5Cfrac%7Bd%7D%7Br%7D%5C%5C%5C%5C%5CRightarrow%20t%3D%5Cfrac%7B10%7D%7B0.5%7D%3D20%5C%20hr)
Answer:
4 cm
Step-by-step explanation:
Take the 11 cm on the bottom and subtract the 7 cm right above it.
Imagine the bottom half of this shape as a rectangle, the bottom and top side are of the same length. The top side would have to be 11 cm in length as well, so just subtract 11-7 to get the missing part.
Answer: y= -3x + 10
Step-by-step explanation: i just did it
The solution to the systems if equation y = 4x - 5, y = 2x + 3 is (x, y) = (4, 11)
<h3>Equation</h3>
y = 4x - 5
y = 2x + 3
4x - 5 = 2x + 3
4x - 2x = 3 + 5
2x = 8
x = 8/2
x = 4
y = 4x - 5
= 4(4) - 5
= 16 - 5
y = 11
Therefore, the solution to the system of be equation is x = 4 and y = 11
