HELP PLSSSSS
ludmilkaskok [199]

Answer:

a=21

AB=23.9

BC=19.5

CD=(23.9)

AD=19.5

Step-by-step explanation:

Each pair of parallel sides are equal in a parallelogram. Sense both pairs use the same variable we can just choose the easiest to solve which would be:

a-1.5=19.5

add 1.5 to both sides

a=21

now substitute 21 in for a in each equation.

AB=CD so

AB=23.9

BC=AD so

BC=19.5

CD=(21)+2.9 so

CD=(23.9)

AD is given so

AD=19.5

How many moles are in a sample of 3.01 x 10^18 formula units of sodium hydroxide (NaOH)?
Lunna [17]

Step-by-step explanation:

We can use the formula to find the number of moles. As ,

:\implies n = No. of particles/ N_A

:\implies n = 3.01× 10¹⁸/6.022 × 10²³

:\implies n = 1/2 / 10⁵

<h3>Hence the number of particles is 1/2 / 10⁵ </h3>

If (x) =7-3x, determine the value of x when f(x)=16.
melomori [17]

Answer:

f=16/7.3x

Step-by-step explanation:

Lets solve for f:

f(7.3)=16

Step 1:Divide both sides by 7.3x

7.3f/7.3x=16/17.3x
