57 cubic decimeter equivalent to ? deciliter
I am in Secondary 3.
Is is the same as before? (19 liter equivalent to ? cubic decimeter)

57 cubic decimeter equivalent to 570 deciliter

19 liters equivalent to 19 cubic decimeter

Step-by-step explanation:

Let us revise the change of some quantities

Lets solve the problem

we need to convert 57 cubic decimeter to deciliter

Let us use the ratio method

1 cubic decimeter = 10 deciliters

→  decimeter³  :  deciliter

→  1                    :  10

→  57                 :  x

By using cross multiplication

∴ 1 × x = 57 × 10

∴ x = 570

57 cubic decimeter is equivalent to 570 deciliter

We need to convert 19 liter to cubic decimeter

Let us use the ratio method

1 liter = 1 cubic decimeter

→  liter  :  decimeter³

→  1       :  1

→  19     :  y

By using cross multiplication

∴ 1 × y = 19 × 1

∴ y = 19

19 liters equivalent to 19 cubic decimeter

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
