Answer:

5 L

Step-by-step explanation:

As given in question,

1 L can fill 4.2 cups.

So, 1 cup can hold \frac{1}{4.2} L of fluid.

Therefore,

21 cups can hold = \frac{1}{4.2} × 21

                            = 5 L

So, there is 5 L of fluid in 21 cups.

A book has 12 chapters. The mean length of the chapters is 40 pages. How many total pages are there in the 12 chapters?
amm1812

Answer:

480

Step-by-step explanation:

Important Information:

A Book Has 12 Chapters.

The Mean length of the chapters is 40 pages.

Question to Answer:

How many total pages are there in the 12 chapters?

Explanation/Solution:

Let's assume that the total number of pages in the book is "x" pages.  

To find the mean (average) we divide the total "x" by 12 because there are 12 chapters in the book, which would equal to 40.  

\frac{x}{12}=40

Multiply both sides by 12...

x = 480

Hence, The total number of pages in the 12 chapters is 480.

Solve for the missing angle. Round to the nearest hundredth.<br> 18<br> ?<br> 13<br> ? =<br> degrees
skad [1K]

Answer:

\theta \:=43.76^{\circ \:\:}

Step-by-step explanation:

The right triangle has the hypotenuse = 18

Let 'Ф' be the missing angle

we know that

cos Ф = adjacent/hypotenuse

Here,

  • The adjacent to Ф = 13
  • The hypotenuse = 18

so

cos Ф = adjacent/hypotenuse

cos\:\theta \:=\frac{13}{18}

\theta \:=\cos ^{-1}\left(\frac{13}{18}\right)

   =43.76^{\circ \:}

Therefore, the missing angle is:

\theta \:=43.76^{\circ \:\:}

I need those two step by step
Naddik [55]

<u>Answer:</u>

h= 1/4; g = 4

<u>Step-by-step explanation:</u>

1. 3/5h - 1/10 = h/5

First multiply by 10 to get rid of the fractions

(10)3/5h - (10)1/10 = (10)h/5

6h - 1 = 2h

Add one to each side

6h = 2h + 1

Subtract 2h from each side

6h - 2h = 1

4h = 1

Divide 4 by each side

h = 1/4

2. 3g - 10/4 = 1/2

Multiply each side by 4 to get rid of fractions

(4)3g - 10/4 = (4)1/2

3g - 10 = 2

Add 10 to each side

3g = 12

Divide each side by 3

g = 4
