(1) a) 5270 cl= ? dal

Ivanshal [37]

Answer:

Check below

Step-by-step explanation:

1) These metric volume units can be easily converted by dividing or multiplying by 10 and its multiple. Like this: each step up on the ladder multiply by 10. Each step down divide by 10

$a)5270 \:cl=527\:dl\\b)kl=5.3 \times 10=530 hl\\c)58000ml=5.8 dal =(\frac{58000}{10000})\\d)0.39 dal=3.9 l\\e)7.8 dal=780 dl\\f)57.2 ml=5.72 cl$ .

2) When it comes to area, the "ladder scheme" remains valid but now we'll multiply or divide by

$10^3$

Bear in mind these useful relations:

$1litre =\frac{1}{10^3}m^{3}$

$1 cm^{3} =1 ml$

$a) 3.7 l=3700 cm^{3}\\b)29.6 dm^{3}\\29.6 dm^{3} \rightarrow 29.6\times10^{3} cm^3=29.6\times10^{3} ml = 29.6\times10^{2} cl \:or\:2960 cl\\c)8.1l=8100 cm^{3}\\d)5l=\frac{5}{10^{-3}} m^{3}\\e)5.2 cl=52ml=52 cm^{3}=52\times10^{3}=52000 \:mm^{3}\\f)375 ml=375 cm^{3}\\g) 1300 cm^{3}=1300 ml=13 dl\\h) 8.6 ml= 8.6 cm^{3}\times\: 10^{3}=8600 mm^{3}\\i) 51.8\times 10^{11} l \rightarrow 51.8\times 10^{-11}km^{3}$

Help me please #7!!!!!!

MatroZZZ [7]

Applying parallel line postulate twice

36degree=3x degree +2y degree

126 degrees=12 x degree + 2y degree

So, the two equations are:

3x + 2y = 36

and

12x + 2y = 126

Eliminate x to solve for y

-(3x + 2y)= -(36)

-3x - 2y = -36

Combine the equations

(-3x - 2y)+ (12x + 2y) = (-36) + (126)

-3x -2y + 12x + 2y = -36 + 126

9x = 90

x = 10

Plug value of x back into to the equations to solve for y

3(10) + 2y = 36

30 + 2y = 36

2y =6

y = 3

Optional

Plug x into the other equation to check for error

12(10) +2y = 126

120 + 2y =126

2y = 6

y = 3

Solve | 5+7= 17.

alisha [4.7K]

The solutions of the absolute value equation is determined as 15 and - 5.

<h3>Solution to the absolute equation</h3>

The solution to the absolute equation is determined as follows;

|x - 5| + 7 = 17

collect similar terms

|x - 5| = 17 - 7

|x - 5| = 10

to resolve the absolute values, form two equations as follows;

x - 5 = 10 and x - 5 = -10

x = 15 and x = -5

Thus, the solutions of the absolute value equation is determined as 15 and - 5.

The complete question is given as;

|x - 5| + 7 = 17

There are two atoms of hydrogen and one atom of oxygen in one molecule of water . How many atoms of hydrogen are there in 51 mol

Alex777 [14]

If there are two hydrogen atom molecules in one atom of water you'd do 51 times 2, getting you 102 hydrogen atoms in 51 water molecules.

Alex73 [517]

Answer:

Solution given:

AD=1.8

AC=3.0

we have

∆ADC is a right angled triangle

Cos A=b/h

<A=cos-¹ (1.8/3)

<A=53.13°

again

∆ABC is a right angled triangle

Tan A=p/b=BC/AC

Tan 53.13×3=BC

BC=4

NOW

Area of triangle =½(AC*BC)=½(4×3)=6 square units is a required area.
