Answer:
Required equation is 42 = 5 + 3.70d
Step-by-step explanation:
Emma took a taxi from the airport to her house. She paid a flat fee of $5 plus $3.70 per mile.
The fare came to $42
Flat fee = $5
Variable fee = $3.70 per miles
Total fare = $42
Let Emma traveled d miles
Total fare = Flat fee + variable fee of d miles
According to given info.
42 = 5 + 3.70d
Now we solve for d,
Therefore, d=10 miles
Thus, Required equation is 42 = 5 + 3.70d , d=10 miles
It is c because if you divide it it equals to .75
William needs 102.6 fencing in all because 76.9 plus 25.7 equals 102.6, hope this helps!
The area of a triangle can be shown in the equation Area=1/2(base)(height). Since you are given area and height, you can just solve for the base.
6=1/2(base)(4) ---> 6=2(base) ---> base=3
Answer: 2 hours
Step-by-step explanation:
Given : Working alone at their respective constant rates, machine A and machine B can fill a certain order in 3 hours and 6 hours, respectively.
Let t be the time taken by both of them working together.
Then, according to the question, we have
![\dfrac{1}{t}=\dfrac{1}{3}+\dfrac{1}{6}\\\\\Rightarrow\dfrac{1}{t}=\dfrac{2+1}{6}\ \ [\because\ L.C.M. (3,6)=6]\\\\\Rightarrow\dfrac{1}{t}=\dfrac{3}{6}=\dfrac{1}{2}\\\\\Rightarrow t=2](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7Bt%7D%3D%5Cdfrac%7B1%7D%7B3%7D%2B%5Cdfrac%7B1%7D%7B6%7D%5C%5C%5C%5C%5CRightarrow%5Cdfrac%7B1%7D%7Bt%7D%3D%5Cdfrac%7B2%2B1%7D%7B6%7D%5C%20%5C%20%5B%5Cbecause%5C%20L.C.M.%20%283%2C6%29%3D6%5D%5C%5C%5C%5C%5CRightarrow%5Cdfrac%7B1%7D%7Bt%7D%3D%5Cdfrac%7B3%7D%7B6%7D%3D%5Cdfrac%7B1%7D%7B2%7D%5C%5C%5C%5C%5CRightarrow%20t%3D2)
Hence, it will take 2 hours by the two machines .
