1 yard = 36 inches
Then 12 characters/inch * 36 inch/yard = 432 characters / yard.
The answer is 432 characters per yard of text.
Answer: Jim can lay 25 tiles per hour.
Step-by-step explanation:
Let be "x" Jim's rate and "y" Pete's rate.
We know that Jim completed half the floor in 4 hours, then:
![4x](https://tex.z-dn.net/?f=4x)
And Pete completed the other half of the floor in 2 hours, then:
![2y](https://tex.z-dn.net/?f=2y)
Since Jim completed half the floor and Pete completed the other half:
[Equation 1]
We also know that Pete can lay 25 more tiles per hour than Jim, then:
[Equation 2]
Then, we can substitute Equation 2 into Equation 1 and solve for "x":
![4x=2(x+25)\\\\4x=2x+50\\\\4x-2x=50\\\\x=\frac{50}{2}\\\\x=25](https://tex.z-dn.net/?f=4x%3D2%28x%2B25%29%5C%5C%5C%5C4x%3D2x%2B50%5C%5C%5C%5C4x-2x%3D50%5C%5C%5C%5Cx%3D%5Cfrac%7B50%7D%7B2%7D%5C%5C%5C%5Cx%3D25)
Therefore, Jim can lay 25 tiles per hour.
Answer:
C
Step-by-step explanation:
multiply the bracket components by 4 you will find that 4*2x=8x. And 4*1=4
There are 180 Degrees in a triangle, you know two, 90 and 79, so the last angle is 11
180-90-79=11
