Answer:
The number of chirps per minute is 72
Step-by-step explanation:
Here, using the formula given, we want to find the number N representing the number of chirps per minute.
To get this, we shall simply substitute the value of 58 for T in the equation;
Thus;
58 = 50 + (N-40)/4
58 -50 = (N-40)/4
8 = (N-40)/4
4 * 8 = N -40
32 = N -40
N = 40 + 32
N = 72

it is c
Step-by-step explanation:
Since it’s in percents, put the percent over 100 as a fraction and simplify them. For percents that aren’t given, add the rest and subtract it from 100 and then place it as a fraction over 100
Okay! So to start this problem, we need to look at the given information a little closer to make sure we have everything we need! This is a triangular pyramid, meaning that it has a total of 4 sides, which are all congruent triangles, meaning they all have the same surface area! We are also given the total surface area, which is 2304 cm^2.
If we need to find out how big one of the sides are, we should just have to divide the total surface area by 4, because there are 4 sides with the same surface area! 2304/4 = 576 cm^2, so your answer should be A) 576 cm2!
