Answer:
the answer is x=0.36. (-20x=-7.2) divided by -20 equals to x=.36
By looking the given options, we can say that some of them are following pythagorean identities and pythagorean identities are
sin^2(x) + cos^2(x) =1, sec^2(x)-tan^2(x) =1,csc^2(x) -cot^2(x)=1
So out the four options, option a and option c are following pythagorean identity and option b and option d are not following pythagorean identity. And we have to find those options which are not identities .
So the correct options are
b) sec^{2} x+csc^{2} x=1 \ d) tan^{2} x + sec^{2} x =1
If you would like to know the maximum number of toys that can be put into each box, you can calculate this using the following steps:
the area of a toy: 1/2 * 1/2 = 1/4 square inch
the area of a box: 9 1/2 * 7 1/2 = 19/2 * 15/2 = 285/4 = 71 1/4 square inches
71 1/4 / 1/4 = 285/4 / 1/4 = 285/4 * 4/1 = 285 toys
The company can put 285 toys in each box.
Answer:
Total no. of houses = 140
Step-by-step explanation:
Let there are 9x flats and 5x bungalows.
Total bungalows = 50
It means,
5x = 50
x = 10
No of flats = 9x
= 9(10)
= 90
Total houses = no. of flats + no. of bungalows
= 50+90
= 140
So, there are 140 houses in the village.
