same units.

The ratio of 18 rides, 30 games, and 8 water slides.  can be written as

18:30:8

in the simplest form it is expressed as

9:15:4

in other way it is expressed as

9 to 15 to 4

another type of ratio is the two term ratio

N is inversely proportional to t and when t is 36 ,N is176 .
sergeinik [125]

Answer:

The answer is below

Step-by-step explanation:

N is inversely proportional to t, therefore:

N ∝ 1/t

Let k be the constant of proportionality, hence we can replace the relationship by:

N = k/t

Given that when t is 36, N is 176. Therefore we can find the value of k:

176 = k / 36

k = 176 * 36 = 6336

N = 6336/t

Also let us find N when t = 6. This is done by substituting t = 6 into the equation and simplifying:

N = 6336/6

N = 1056

Help me with this question ​
enot [183]

Answer:

37.2

Step-by-step explanation:

when you turn the small triangle LMN to its right angle to cover the right angle of KLM, you find that they are similar triangles.

therefore the corresponding side lengths are at the same ratio.

LM/KM = MN/LN

LM = 24

MN = 13

we can get LN via Pythagoras of the small triangle

LN² + MN² = LM²

LN² + 13² = 24²

LN² = 24² - 13² = 576 - 169 = 407

LN = sqrt(407) = 20.174241

now back to our main problem

24/KM = 13/sqrt(407)

24×sqrt(407)/13 = KM = 37.2

Im confused about this darn question can someone please solve it for me
n200080 [17]

Answer: The answer is A : 6x^2+24x+24

Step-by-step explanation:

(2x+4)(3x+6)

multiple the two equations together

2x*3x=6x^2

2x*6=12x

4*3x=12x

4*6=24

combine like terms

6x^2+12x+12x+24

6x^2+24x+24
