find the value of x

Answer:

150

Step-by-step explanation:

The ratio is 3:5, so you can make this equation:

[tex]3x+5x=240[/tex], because for any integer x, the ratio will stay the same.

solve that:

[tex]3x+5x=240\\8x=240\\x=30[/tex]

We're not down yet!

we need to find 5x, not x.

[tex]5*30=150[/tex]

There are 150 non-fiction books in the library.

check!

150+90=240

The are 150 non-fiction books are in the library.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

The ratio of fiction to non-fiction books at school library is 3 to 5.

Total books = 240

So, the number of non fiction books

= 240 x 5/8

= 30 x5

= 150

Hence, there are 150 non fiction book.

Given:

Side length of square is x = 10 in.

To find:

Area of a square with side length x when x = 10 in.

Check whether the area of a square and the length of its side directly proportional.

Solution:

Area of square is

[tex]Area=(side)^2[/tex]

[tex]Area=x^2[/tex]

For x=10, we have

[tex]Area=(10)^2[/tex]

[tex]Area=100[/tex]

Therefore, the area of square is 100 sq. in. when x=10 in.

For x=1,

[tex]A_1=1^2=1[/tex]

[tex]\dfrac{A_1}{x_1}=\dfrac{1}{1}=1[/tex]

For x=2,

[tex]A_2=1^2=4[/tex]

[tex]\dfrac{A_2}{x_2}=\dfrac{4}{2}=2[/tex]

Here, [tex]\dfrac{A_1}{x_1}\neq \dfrac{A_2}{x_2}[/tex].

Since, [tex]Area=(side)^2[/tex] and ratio of area and sides are not always same, therefore the area of depends on the side but not directly proportional to its side.

Answer:

The numbers are -11 and -9.

Step-by-step explanation:

The two numbers are x and y.

x = y - 2

2y = 5x + 37

2y = 5(y - 2) + 37

2y = 5y - 10 + 37

3y = - 27

y = -9

x = - 11

Answer:

Step-by-step explanation:

y = f(x) = - [tex]\frac{1}{2}[/tex] x - 3

f(- 4) = - [tex]\frac{1}{2}[/tex] (- 4) - 3 = - 1

f( - 2) = - [tex]\frac{1}{2}[/tex] (- 2) - 3 = - 2

Step-by-step explanation:

26=6k+8-6+2k

combine all common integers from the same side, (8-6) and (6k+2k).

8-6=2

6k+2k=8

Which now translates the equation to 26=8k+2.

26=8k+2

continue by moving the (2) to the other side, do so by subtracting 26-2.

26-2=24

24=8k

Lastly, move the 8 to the other side of the equation by dividing 24/8.

24/8=3

Therefore, k=3

Answer:The answer would be x=c+k/4

Step-by-step explanation:

The required solution for the equation ax -c = k for x is x = (k + c)/4.

Given that,
To determine the solution of the equation  4x- c= k for x.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
4x - c = k
Now, simplifying the above equation for x,
4x - c = k
4x = c + k
x = (c + k) / 4

Thus, the required solution for the equation ax -c = k for x is x = (k + c)/4.

Answer:

As the height of warehouse is greater than the height of crate, the crate will fit in the warehouse.

Step-by-step explanation:

Given that

Volume of cube = V = 2197 cubic feet

Side of cube = a =?

Height of ware house = h = 14 feet

In order for the crate to fit in the warehouse the height of crate has to be less than the height of warehouse i.e. a<h

In order to check this we have to find the side/height of crate

So,

[tex]V = a^3\\2197 = a^3[/tex]

Taking cube root on both sides

[tex]\sqrt[3]{a^3} = \sqrt[3]{2197}\\\sqrt[3]{a^3} = \sqrt[3]{13^3}\\ a = 13\ feet[/tex]

So the height of cube is 13 feet.

Comparing the height of c and height of ware house we can conclude that

Height of Warehouse > Height of crate

h>a

14>13

As the height of warehouse is greater than the height of crate, the crate will fit in the warehouse.

Answer:

Arithmetic content = 300 pages

Geometric content = 180 pages

Step-by-step explanation:

Arithmetic : Geometry = 5 : 3

Total pages of book = 480

How much of each type of content will be needed to make a book of 480 pages?

Total ratio = arithmetic + geometric

= 5 + 3

= 8

Arithmetic content = 5 / 8 × 480

= 0.625 × 480

= 300

Arithmetic content = 300 pages

Geometric content = 3 / 8 × 480

= 0.375 × 480

= 180

Geometric content = 180 pages

The kilogrammes of calcium found in 173 pounds of calcium is = 78.5 kg. That is option A.

First convert the 173 pounds of calcium to gramma

1 lb(pounds) = 454 g;

Therefore 173 pounds = 173 ×454

                                    = 78,542g

But,             1000 g = 1kg

Therefore, 78542g = 78542  ÷1000

                                = 78.542

                                =78.5kg.

Therefore, the kilogrammes of calcium found in 173 pounds of calcium is = 78.5kg.

The pair of functions that used for developing the graph of g and w is [tex]q(x)=18x^2\ and\ W(X) = x^2[/tex]

The vertex of a parabola should be the point where the parabola crosses its axis of symmetry. In the case when the coefficient of the x2 term is positive, so the vertex will be the lowest point on the graph.

Since The vertex of the graph of g is 18 units below the vertex of the graph of w so the above functions should be considered.
