Answer:
270 km
Step-by-step explanation:
Distance is related to speed and time by ...
distance = speed · time
distance = (90 km/h)(3 h) = 270 km
The car will travel 270 km in 3 hours.
Here, we need to set up an equation. So since the two angles need to add up to 90, and x will represent the angle, the initial equation will look like this. x=90-x. When you plugin the 14, it will look like x=14(90-x) and that gives you x=1490-14x. Add the 14x to the left and it becomes 15x=1490. Divide by 15 and you get x=84. That is the first angle. Now, we subtract 84 from 90 and we get 6. therefore the angles are 84 and 6 degrees.
Hope this is clear enough.
Answer:
Step-by-step explanation:
When a circle is rolled out, the base becomes πr and the heignt of each cone becomes r, therefore when the circle is made the equation become πr²
