With in quadrant 3, we should expect both and to be negative, so that is positive. The corresponding reciprocal expressions will have the same sign.
Recall that , which means
Also recall that , so
Only the first two options are correct.
Answer:
the answqee is D.
Step-by-step explanation:
Answer:
<em>The sea cow can stay under water for 16 minutes.</em>
Step-by-step explanation:
A hippopotamus can stay under water for 15 minutes.
A sea cow can stay under water minutes and this is 11 minutes longer than one-third the time a hippopotamus can.
So, "11 minutes longer than one-third the time a hippopotamus can" means:
Thus, the equation will be:
Now, solving the above equation, we will get.........
So, the sea cow can stay under water for 16 minutes.
Scaling on map is defined as the ratio of a distance on the map to the corresponding distance on the ground.
Here, 3.2 centimeters on the map is equivalent to 4 kilometers.
We can use unitary method to find, how many kilometer/kilometers each centimeter corresponds to.
Using the unitary method:
Therefore, the scale of map represents 1.25 kilometers for each centimeter.
after each number you had 11
so when you subtract
32-12 = 11
now add this 11 to 43
11+43 = 54
so the next numbers are 45 and 54
