Answer:

Step-by-step explanation:

Consider the right triangle with hypotenuse of 60 yards and the height 12 being the side opposite the angle of incline, say x°, then

sinx° = $\frac{opposite}{hypotenuse}$ = $\frac{12}{60}$ , thus

x = $sin^{-1}$ ( $\frac{12}{60}$ ) ≈ 11.54°

So this has to do with permutations and honestly I need an explanation on how I can figure these out.

Well, the answer quite simple ....there are 4! ways to arrange these numbers...and as 4! = 4*3*2*1 = 24

hence 24 is the correct answer....

u can also remember it by theorem of multiplication as.....in first place (I.e. first code can be any no. out of 4,5,2&7 ....so 4*.....

as first place is acquired by a certain no. that leaves three no. to fill third place and when third place I'd occupied it leaves 2 numbers to fill second place and lastly only one no. to fill the last place .....so it's result will be like 4*3*2*1.

I know this is pretty much confusing ....but still I tried my best....

if anything troubles u here feel free to ask me

There's no need to get into an ethical morass over math homework.

111.

M is 20% less than N means

M is 100-20=80% of N

M=0.80 N

M/N = 0.8 = 4/5

Ratio: 4/5

112.

When we know a, the average, and n, how many numbers there are, we know the sum s, because a=s/n so s=na.

So the sum of our six numbers is 6(3.5)=21 so the sum of the seven numbers is 21+4.2=25.2 so the average is 25.2/7 = 3.6

Answer: 3.6

113.

|2p + 4 | < 3

At p=-2 the absolute value is zero. As p gets more negative the absolute value argument (inside part) gets negative and the absolute value gets bigger, more positive. Eventually the inside will be exactly -3, when

2p +4 = -3

2p = -7

p = -7/2 = -3 1/2

So p=-4 will make the inequality false, and p=-3 is the smallest integer that makes the inequality true.

Answer: -3

114.

The distance from the origin is given by the Pythagorean Theorem and this one is a 3/4/5 right triangle:

$d = \sqrt{(-.3)^2 + (-.4)^2}=.5$

Answer: .5 or 1/2
