13.54 g/mL = (100 g)/v

==>   v = (100 g)/(13.54 g/mL) = 7.39 mL

The volume of 100 grams of mercury is 7.38 mL when the density of mercury is 13.54 g/mL.

To calculate the volume of 100 grams of mercury, we can use the density formula:

Density = Mass / Volume

We are given the density of mercury as 13.54 g/mL, and we want to find the volume in mL.

Volume = Mass / Density

Substituting the given values:

Volume = 100 g / 13.54 g/mL

Simplifying the division:

Volume= 7.38 mL

Therefore, the volume of 100 grams of mercury is 7.38 mL.

Answer:

He paid $9 twelve times

12× 2= 24 days

Step-by-step explanation:

1st day = $16.60

3rd day=$ 9 (i.e for every 2days afterwards)

5th day=$ 9

Yuri pays : 124.60

124.60-16.60

= $108.00

After paying the first day he paid 108.00

108.00÷ 9 = 12

He paid $9 twelve times

12× 2= 24 days

As I write this Reiner is standing at my side. He knows this is a love letter but he’s still sneaking glances. Honestly it’s no wonder the creep is still single.

That said, he did give me his word that he’d deliver this letter to you. He says he owes me for the time I doubled back to save him.

I’m sorry about that. I never would have imagined myself choosing those two over you.

Answer:

a because I dont know why but some one told me it was this

Answer: A. There are three terms

Concept:

In an algebraic expression, there are several specific terms:

If you are still confused, you may refer to the attachment below for a graphical explanation.

Solve:

a. There are three terms. [tex]\boxed{FALSE}[/tex]

- 14b

- -7

- 8b

- b

There are in total four individuals, which means there are four terms.

b. There is one constant term. [tex]\boxed{TRUE}[/tex]

- 14b is a [variable + coefficient]

- -7 is a [constant]

- 8b is a [variable + coefficient]

- b is a [variable]

Therefore, there is one constant term.

c. The coefficients are 14, 8, and 1 [tex]\boxed{TRUE}[/tex]

- 14b →→→ 14 is the [coefficient]

- -7 →→→ is a [constant]

- 8b →→→ 8 is the [coefficient]

- b →→→ 1 is the [coefficient]

Therefore, 14, 8, and 1 are coefficients.

d. Three of the terms are like terms [tex]\boxed{TRUE}[/tex]

- 14b →→→ b is the [variable]

- -7 →→→ is a [constant]

- 8b →→→ b is the [variable]

- b →→→ b is the [variable]

Since 14b, 8b, and b share the common variable, there are three like terms.

Hope this helps!! :)

Please let me know if you have any questions

Answer:

Step-by-step explanation:

Translation left or right adds to x-coordinate, translation up or down adds to y-coordinate.

Given coordinate (0, 2) and translation is 2 units right and 4 units down:

The end points is (2, -2)

We have to move x co ordinates 2 more and y coordinate 4less

Do it

[tex]\\ \sf\longmapsto (0,2)[/tex]

[tex]\\ \sf\longmapsto (0+2,2+(-4))[/tex]

[tex]\\ \sf\longmapsto (2,2-4)[/tex]

[tex]\\ \sf\longmapsto (2,-2)[/tex]

We will end at (2,-2)

Step-by-step explanation:

if I understand the typed information here, we have

(-4 + 8x) + 3 > -4

so, I am looking at that :

-4 + 8x + 3 > -4

let's first add 4 on both sides

8x + 3 > 0

then subtract -3 on both sides

8x > -3

and finally divide both sides by 8

x > -3/8

since we never multiplied or divided by a negative number, the inequality sign stays the same.

so, this inequality is true for all x > -3/8

Answer:

B (Base surface area) = 16 [tex]m^{2}[/tex]

P (Perimeter of the base) = 16 m

H (Height) = 6 m

L (Not sure what L means. I assume it's the slant height??) =  6.32 m

LA (I assume lateral surface area) = [tex]50.59 m^{2}[/tex]

SA (I assume total surface area) = [tex]66.59 m^{2}[/tex]

V (volume) = [tex]32 m^{3}[/tex]

Step-by-step explanation:

Sorry if anything is wrong. It would be more helpful to put the names, instead of acronyms.

Perimeter of base=4(4)=16m

Area of base=4²=16m²

Height=6m

Slant height=6.3m

Lateral surface area=4(1/2(4)(6.3))=8(6.3)=50.54m²

Total surface area=50.54+16=66.54m²

Volume=a²h/3=4²/(6)/3=16(2)=32m³

Solving for Angles

[tex]\displaystyle \frac{a^2 + b^2 - c^2}{2ab} = cos∠C \\ \frac{a^2 - b^2 + c^2}{2ac} = cos∠B \\ \frac{-a^2 + b^2 + c^2}{2bc} = cos∠A[/tex]

* Do not forget to use the inverse function towards the end, or elce you will throw your answer off!

Solving for Edges

[tex]\displaystyle b^2 + a^2 - 2ba\:cos∠C = c^2 \\ c^2 + a^2 - 2ca\:cos∠B = b^2 \\ c^2 + b^2 - 2cb\:cos∠A = a^2[/tex]

Answer:

The numbers are 8, 24 and 30

Step-by-step explanation:

Let x be the first number.

If the second number is triple the first, then the second number is 3x

If the third number is the second number plus six, then the third number is 3x + 6

So therefore the equation is:

[tex]x + 3x + (3x + 6) = 62[/tex]

Solving for x,

[tex]x + 3x + 3x + 6 = 62\\7x = -6 + 62\\7x = 56\\x = 8[/tex]

But why is the second number 24?

[tex]3x = 24\\3(8) = 24\\24 = 24[/tex]

And why is the third number 30?

[tex]3x + 6 = 30\\24 + 6 = 30\\30 = 30[/tex]
