The point of intersection of two straight line graphs is the point with coordinates that satisfies both lines equations

The length of segment EF is presented as follows;

[tex]EF =\underline{\mathbf{ 17\dfrac{1}{7} \ ft.}}[/tex]

The reason why the above value is correct is as follows;

The given parameters are;

Height of right triangle ACD = 40 ft.

Height of right triangle BCD = 30 ft.

Required:

To find the length of EF

Solution:

The equation of the lines AC and BD are found and equated to find the height of EF as follows;

The slope of AC = [tex]\dfrac{-40}{CD}[/tex]

The equation of AC  is presented as follows;

[tex]y - 40 = \dfrac{-40}{CD} \times (x - 0)[/tex]

[tex]y = \dfrac{-40}{CD} \times x + 40[/tex]

The slope of BD = [tex]\dfrac{30}{CD}[/tex]

The equation of BD is given as follows;

[tex]y - 30 = \dfrac{30}{CD} \times (x - CD)[/tex]

[tex]y = \dfrac{30}{CD} \times (x - CD)+ 30[/tex]

Equating both values of y to find the value of y at the intersecting point E, gives;

[tex]\dfrac{-40}{CD} \times x + 40 = \dfrac{30}{CD} \times (x - CD)+ 30[/tex]

Which gives;

[tex]\dfrac{40 \cdot CD - 40 \cdot x}{CD} = \dfrac{30 \cdot x}{CD}[/tex]

Therefore;

40·CD - 40·x = 30·x

[tex]CD = \dfrac{70\cdot x}{40} = \dfrac{7\cdot x}{4}[/tex]

[tex]CD = \dfrac{7\cdot x}{4}[/tex]

Therefore, at E, we have;

[tex]y = EF= \dfrac{40 \cdot CD - 40 \cdot x}{CD} = \dfrac{30 \cdot x}{CD}[/tex]

[tex]y = EF = \dfrac{40 \times \dfrac{7}{4}\cdot x - 40 \cdot x}{\dfrac{7}{4}\cdot x} = \dfrac{30 \cdot x}{\dfrac{7}{4}\cdot x} = \dfrac{120}{7} = 17\dfrac{1}{7}[/tex]

[tex]\underline {EF = 17\dfrac{1}{7} \ ft.}[/tex]

The height of the tank if it’s radius is 16 feet is,

⇒ Height = 9.02 feet

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A cylindrical fish tank at the zoo has a capacity of 7252 cubic feet.

Now, We know that;

Volume of a cylinder = π × radius² x height

Here, Radius is 16 feet.

Hence, We get;

Volume of a cylinder = π × radius² x height

7252 = 3.14 × 16² × h

⇒ 7252 = 803.84 h

⇒ h = 7252 / 803.84

⇒ h = 9.02 feet

Thus, The height of the tank if it’s radius is 16 feet is,

⇒ Height = 9.02 feet

Answer:

Answer:

equation 6+(½×n). n means the number of months

The equation that represents the situation is y = 6 + (1/2)x.

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

A baby giraffe measures 6 feet tall when it is born.

Initial height of baby=6 feet.

Average growth per months = 1/2

                                               =0.5 feet

Let x be the number of months.

And the height of a baby giraffe is y feet.

So equation is,

y = 6+0.5x

or, y = 6 + (1/2)x.

Therefore, the equation is  y = 6 + (1/2)x.

Answer:

r = 3

Step-by-step explanation:

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

Slope 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of a line passing through (4, 2) and (r, -6) is 8.

8 = [tex]\frac{2+6}{4-r}[/tex]

8(4 - r) = 8

4 - r = 1

r = 4 - 1

r = 3

Answer:

The amount that each flower pot will hold is 3 1/5 quarts of soil.

Step-by-step explanation:

Since there's 16 quarts of soil being used to fill 5 flower pots, we just need to divide 16 by 5. 16 ÷ 5 = 3.2. This is a decimal, so we need to convert it into a mixed number. 3.2 is 3 2/10, which can be simplified into 3 1/5. Hope this helped!! :]

The elevator is on the 8th floor.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

3 - 6 = -3 is an expression

We have,

An elevator is on the 10th floor.

It goes down 6 floors.

This can be written as an expression:

10 - 6 = 4

The elevator is on the 4th floor.

The elevator then goes up 4 floors.

This can be written as an expression:

4 + 4 = 8

The elevator is on the 8th floor.
