Whats the absolute value of 5/6?

Answers

Answer:

the absolute value of 5/6 is 5/6

Step-by-step explanation:

absolute value is just the distance from zero on a number line, so it just makes whatever number under the | x | the same number but positive.

Answer:

5/6 is the same you dont change it unless its negative

Step-by-step explanation:

If the fraction is positive, it is its own absolute value. If the fraction is negative, remove the negative sign. That is the absolute value. In other words, the absolute value of 1/7 is 1/7, and the absolute value of -5/8 is 5/8.

What are similar triangles?

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

From the given figure, ΔJKL, ΔJKM and ΔKML are right angle triangles.

Now, consider ΔJKL and ΔJKM

∠JMK=∠JKL (Measure of angle is equal to 90°)

∠KJM=∠KJL (Reflexive property)

ΔJKL and ΔJKM are similar triangles

Consider ΔJKL and ΔKML

Answer:

x = x + 7

Step-by-step explanation:

In this equation, it is saying that x is equal to itself plus something else (7). This equation does not make sense at all because x cannot equal to something that is bigger or smaller than itself. If 7 is added to x, like the right-hand side of the equation, it cannot be equal to x from the left-hand side of the equation, so there is no solution to the value of x in this equation.

A gift basket has 2 soaps and 5 lotions and costs $20. A second basket has 6 spas and 15 lotions and cost $60. Is it possible to determine the price of the soap?

Answers

A second basket has 6 spas--- I think you mean 6 soaps , so i will work with that

Answer:it is not possible to determine the price of the soap with the information given.

Step-by-step explanation:

Let s0ap be represented as x

and lotion be represented as y

2 soaps and 5 lotions costing  $20 gives us equation 1 as

2 x+ 5y= 20-------- equation 1

second basket with 6 soaps and 15 lotions and costing $60 gives us equation 2 as

6x + 15y= 60------equation 2

Step 2 -- Solving

2 x+ 5y= 20-------- equation 1

6x + 15y= 60--------equation 2

BY elimination method, we  multiply equation 1 by (3)

2x + 5y= 20  x (3)

6x + 15y=60-------equation 3

Subtraction of equation 3 from equation 2 gives us

6x + 15y=60-------equation 3

-6x + 15y= 60--------equation 2

0x +0y=0  which is no solution

Therefore it is not possible to determine the price of the soap

In every equation b = 170, so

The equation is  y =mx + 170

On the line on the graph, for x=2 we have y = 120,so:

 120 = m×2 + 170

This eruption led to the death of 57 people, in addition to permanently changing the surrounding landscape. It is still one of the most disastrous volcanic eruptions in recent history.(2) Mount St. Helens is located in the Cascade Mountain Range in Washington, United States. It is part of the Ring of Fire, an important geological area. This area is home to over 160 active volcanos. Volcanos are active if they have erupted at least once in the last 10,000 years. Mount St. Helens is a stratovolcano. This means it is a steep, evenly shaped cone made of many layers of volcanic rock and ash. These volcanos often have explosive eruptions.(3) Before the eruption of Mount St. Helens, a bulge of rock formed on the northern side of the mountain. Then, early on May 18th, an earthquake occurred that was caused by increasing pressure inside the mountain. This led to a landslide. The force of the landslide collapsed the entire northern side of the mountain, which led to a lateral blast. Lateral blasts occur when volcanos erupt sideways, rather than at the peak. This lateral blast sent rocks flying for miles at high speeds. These blasts destroy forests, buildings, and other structures in a short amount of time. The lateral blast at Mount St. Helens destroyed an area of about 150 square miles. It destroyed forests and left debris in three-inch layers, making the situation even more disastrous.(4) When Mount St. Helens erupted, clouds of deadly ash, volcanic rock, and pyroclastic flows flew outward from the volcano. Pyroclastic flows are more dangerous than lava flows. They are made of gas and volcanic matter. The temperature inside one can reach 1832 F. They move at a speed of more than 50 miles per hour. It is impossible for humans and animals to outrun them. These flows make the eruption of stratovolcanos deadly. As a result, the forests covering the mountain were ruined. Fortunately, there weren't any towns near enough to be destroyed.(5) By the time Mount St. Helens finished erupting, a crater had formed at its top. Forests had been destroyed for miles and rivers had been blocked by debris. Clouds had even blocked out the sun in the entire state.
