450 is the total amount of money and it is divided by 75 to get the total number of books possible under that amount per book. The reason four is added is that it is stated that four of the books necessary are to be taken from a library for free. Therefore, when solved, b is equal to 10

Please help, i will mark as brainliest
harina [27]

Answer:

3.75 L

Step-by-step explanation:

3 liters / 36 m^2 = x liters / 9 x 5 m^2

3 liters / 36 m^2 = x liters / 45 m^2

(45)(3) = (x)(36)

(135) = (x)(36)

x = (135)/(36)

x= 3.75 L

Find the LCM of n^3 t^2 and nt^4.<br><br> A) n 4t^6<br> B) n 3t^6<br> C) n 3t^4<br> D) nt^2
patriot [66]

Answer:

The correct option is C.

Step-by-step explanation:

The least common multiple (LCM) of any two numbers is the smallest number that they both divide evenly into.

The given terms are n^3t^2 and nt^4.

The factored form of each term is

n^3t^2=n\times n\times n\times t\times t

nt^4=n\times t\times t\times t\times t

To find the LCM of given numbers, multiply all factors of both terms and common factors of both terms are multiplied once.

LCM(n^3t^2,nt^4)=n\times n\times n\times t\times t\times t\times t

LCM(n^3t^2,nt^4)=n^3t^4

The LCM of given terms is n^3t^4. Therefore the correct option is C.

How do I find the side lengths for this triangle if only one side and ond angle is given? Plz help
alexandr1967 [171]
The two unknown sides are equal to each other so then the two unknown angles are also equal.

A triangle angles add up to 180
36 + 2x = 180
2x = 180 - 36
2x = 144
unknown angles x = 72°

draw line down center of triangle to make two right triangles with side 22/2 = 11. SOH CAH TOA

cos(72) = 11/H
H = 11/cos(72)
H = 35.6

perimeter = 22 + 2(35.6)
perimeter = 93.2 cm

answer E .
