Answer:
x=6
Step-by-step explanation:
Line ZW and YX are parallel, which means they have the same measurements.
Therefore:
3x+2=20
subtract two from both sides
3x=18
divide by 3
3x/3=18/3
x=6
hope this helps =D
Answer:
• let's first get the percentage decrease:
![= { \rm{100\% - 25 \% }} \\ { \rm{ = 75\%}}](https://tex.z-dn.net/?f=%20%3D%20%7B%20%5Crm%7B100%5C%25%20-%2025%20%5C%25%20%7D%7D%20%5C%5C%20%7B%20%5Crm%7B%20%3D%2075%5C%25%7D%7D)
• then multiply the percentage decrease with the mass given:
![= { \tt{75\% \times 140}} \\ \\ = { \tt{ \frac{75}{100} \times 140}} \\ \\ = { \underline{ \tt{ \: \: 105 \: g \: }}}](https://tex.z-dn.net/?f=%20%3D%20%7B%20%5Ctt%7B75%5C%25%20%5Ctimes%20140%7D%7D%20%5C%5C%20%20%5C%5C%20%20%3D%20%7B%20%5Ctt%7B%20%5Cfrac%7B75%7D%7B100%7D%20%20%5Ctimes%20140%7D%7D%20%5C%5C%20%20%5C%5C%20%20%3D%20%7B%20%5Cunderline%7B%20%5Ctt%7B%20%5C%3A%20%20%5C%3A%20105%20%5C%3A%20g%20%5C%3A%20%7D%7D%7D)
Answer:
75.4m²
Step-by-step explanation:
The shape shown is a cylinder
The volume of a cylinder can be calculated using this formula:
![V=\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h)
where r = radius and h = height
The cylinder shown has a radius of 2m and a height of 6m
Using this information we plug in the values into the formula
![V=\pi 2^26\\2^2=4\\4\pi =12.56637\\12.56637*6=75.39822](https://tex.z-dn.net/?f=V%3D%5Cpi%202%5E26%5C%5C2%5E2%3D4%5C%5C4%5Cpi%20%3D12.56637%5C%5C12.56637%2A6%3D75.39822)
So the area of the cylinder is 75.39822
Our final step is to round to the nearest hundredth
The final answer would be 75.4m²
