If on a scale drawing 15 feet are represented by 10 inches the. A scale 1/10 inches represents how many feet

Goryan [66]

Answer:

A scale 1/10 inches represents 0.15 feet

Step-by-step explanation:

* Lets explain how to solve the problem

- The scale drawing is a ratio between the actual length and the

drawing length

- The terms of the ratio must have same units, then the scale

drawing must have same units

* Lets solve the problem

- The 15 feet on a scale drawing are represented by 10 inch

∵ 1 foot = 12 inches

∴ 15 feet = 15 × 12 = 180 inches

∵ 15 feet represented by 10 inches

∴ 180 inches represented by 10 inches

∴ The scale drawing is ⇒ 10 : 180

- Simplify it by dividing the two terms by 10

∴ The scale drawing is ⇒ 1 : 18

- That means every 1 inch in drawing represents 18 inches in actual

∵ A scale represents 1/10 inches

∴ 1 : 18

1/10 : ?

∴ The actual = 1/10 × 18 = 1.8

∴ 1/10 inches in scale drawing represents 1.8 inches in actual

∵ 1 inch = 1/12 feet

∴ The actual = 1.8 × 1/12 = 0.15 feet

* A scale 1/10 inches represents 0.15 feet

The equation of the line in slope intercept form is y = 2x - 2.

<h3>How to find the equation of a line?</h3>

The equation of a line can be represented in different form such as slope intercept form, point slope form, standard form and general form.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

m = slope
b = y-intercept

Therefore, the slope of the line can be found as follows:

using (0, - 2)(2, 2)

m = 2 + 2 / 2 - 0

m = 4 / 2

m = 2

Therefore, the y-intercept can be solved as follows:

using (0, -2)

y = 2x + b

-2 = 2(0) + b

b = -2

Therefore, the equation is y = 2x - 2

A hiker standing at point G wants to estimate the distance across the lake to point H, which is directly north of her location.

riadik2000 [5.3K]

Answer:

Step-by-step explanation:

The diagram is attached.

Looking at the diagram, we want the side "opposite" of the angle given and the side "adjacent" is given.

Which ratio relates opposite and adjacent? It is Tan.

We can use trigonometry and tan ratio to solve for the distance "x":

$Tan(84)=\frac{x}{650}\\x=Tan(84)*650\\x=6184.4$

D is the correct answer.

Identify the k-value that makes the relationship shown in the table below proportional.

uysha [10]

Answer:

The value of k that makes the relationship shown in the table below proportional is $\mathbf{\frac{1}{2}}$

Step-by-step explanation:

The relation is proportional if $y=kx \:or\:k=\frac{y}{x}$

Putting values of x and y to find k.

For x =2 and y =1 k is: $k=\frac{y}{x}=\frac{1}{2}$

For x =4 and y =2 k is: $k=\frac{y}{x}=\frac{2}{4} =\frac{1}{2}$

For x =6 and y = 3 k is: $k=\frac{y}{x}=\frac{3}{6} =\frac{1}{2}$

For x = 8 and y = 4 k is: $k=\frac{y}{x}=\frac{4}{8} =\frac{1}{2}$

For x =10 and y = 5 k is: $k=\frac{y}{x}=\frac{5}{10} =\frac{1}{2}$

So, The value of k that makes the relationship shown in the table below proportional is $\mathbf{\frac{1}{2}}$
