Answer:
90 degrees
angles are measured in degrees
Answer:
36 x 1/4
Step-by-step explanation:
divide sign can be written in the form 1/x. so by the above equation it means that 36 ÷ 4 = 36 x 1/4
Answer:
First question: 42cm^2
Second question:
whole figure: 150 cm^2
blue part: 96cm^2
white part:54cm^2
Step-by-step explanation:
Lets do math:
look you gave me alot to do but lets go:
Question 1:
lets find the area of the whole rectangle without the parts taken away.
6*10-60
lets put that away for a little bit and move onto the empty space that we have to take away from the rectangle to get this shape.
im now going to subtract 2 from 10 to get 8. I did this to find out the a length
8*3=24
18 is the area of the shape that we have to subtract from the big rectangle
lets now take out the area we put away for a little while.
60-18=42
so 42 is the area of the first shape.
Question #2:
This problem needs multiple answers so lets get started.
first we need to find the area of the big rectangle.
10*15=150
lets put that away for a little bit.
now lets find the area of the little rectangle
6*9=54
to find the blue we have to subtract 54 from 150 which is 96
so now we have this:
area of the whole figure:150
area of the shaded rectangle inside (white): 54
area of the shaded rectangle (blue): 96
phew that was a lot of typing
the end
The two boats picked for the trip are the steamboat and the tall ship. Let us assume that we will take the steamboat going to the island, and then we will take the tall ship for the return trip. We will then relate the distances travelled by both ships to each other.
2. We know that the steamboat takes five hours to complete the trip. The tall ship takes more time, at ten hours to complete the trip. We do not have the exact speeds of the steamboat or of the tall ship, but we do know that the tall ship is 10 knots slower than the steamboat. We likewise do not know the exact distance travelled by either ship, but we do know that both travel the same distance. We want to find out how fast each boat travels. We expect the answers to be in knots, with a difference of 10.
3. We know that distance is equivalent to the product of speed of a boat multiplied by the time of travel. For the trip going to the island, we will use the steamboat. Let its speed be x knots (equivalent to x nautical miles per hour), and let the distance going to the island be d nautical miles. Given that the time takes is 5 hours, this means that d = 5x.
4. If we let x be the speed of the boat you are taking to the island (the steamboat), then we know that the speed of the other boat (the tall ship) is 10 knots less than the steamboat's. So the speed of the tall ship (for the return trip) is (x - 10) knots.
5. Similar to part 3: we will multiply speed by time to determine the distance from the island. From part 4, we have determined that the speed of the tall ship to be used in returning is (x - 10) knots. Meanwhile, the given in the problem says that the tall ship will take 10 hours to make the trip. Therefore the distance will be equal to d = 10(x - 10) = 10x - 100 nautical miles.
6. We can assume that the distance travelled going to the island is the same distance travelled coming back. Therefore, we can equate the formula for distance from part 3 for the steamboat, to the distance from part 5 for the tall ship.
5x = 10x - 100
7. Solving for x: 5x = 10x - 100
-5x = -100
x = 20
Since x is the speed of the steamboat, x = 20 means that the steamboat's speed is 20 knots.
8. We determined in part 4 that the speed of the second boat (in our case, the tall ship) is (x - 10) knots. Since we have calculated in part 7 that the steamboat travels at x = 20 knots, then the speed of the tall ship is (x - 10) = 20 - 10 = 10 knots.
