Answer:

6 feet

Step-by-step explanation:

we know that

The triangles of the figure are similar by AA Similarity Theorem

Remember that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

Applying proportion

Let

x ----> the length of the log in feet

$\frac{x}{8}=\frac{9}{12}\\\\x=8(9)/12\\\\x=6\ ft$

If a pair of jeans cost 45 dollars before the sale and the sale is taking 9 dollars off of the original price what was the perce

Dvinal [7]

Answer:

20%

Step-by-step explanation:

A pair of jeans cost $45 before the sale.

The sale is taking $9 off of the original price.

Then

$45 - 100%

$9 - x%

Write a proportion:

$\dfrac{45}{9}=\dfrac{100}{x}$

Cross multiply:

$45\cdot x=9\cdot 100\\ \\45x=900\\ \\x=\dfrac{900}{45}\\ \\x=20\%$

Write an equation in slope intercept form of the line that passes through the point (-5, -1) with slope -3.

Neporo4naja [7]

Answer:

y= -3x-16

Step-by-step explanation:

slope intercept form is written as y=mx+b. m is the slope, and b is the y-intercept. -3=m

we know that (-5,-1) is 5 points away from the origin, and that the slope is -3, so 5 times -3 equals -15. subtract 15 from -1 (y-coordinate) in order to get the y-intercept (when x=0).

Is 5.3 repeating rational

Goshia [24]

Repeating decimals are considered rational numbers because they can be represented as a ratio of two integers. If a number is terminating or repeating, it must be rational if a decimal is both non terminating and non repeating, the number is irrational.

So yes.
