The solution of given inequalities are x > -3 and x ≤ 5.

How do you solve an inequality?

When resolving an inequality, you can do one of the following: add the same amount to each side; deduct the same amount from each side; multiply or divide each side by the same positive amount. You must flip the inequality sign if you multiply or divide each side by a negative number.

Given inequalities are 2x - 5 > -11 and -10x - 6 ≥ 44.

To solve the first inequality,

2x - 5 > -11

Adding 5 on both sides,

2x - 5 + 5 > -11 + 5

2x > -6

Divide both sides by 2,

x > -3

To solve the second inequality,

-10x - 6 ≥ 44

Adding 6 on both sides,

-10x - 6 + 6 ≥ 44 + 6

-10x ≥ 50

Divide both sides by -10, and change the inequality sign

x ≤ 5

Answers

a trough has ends shaped like isosceles triangles, with width 2 m and height 5 m, and the trough is 10 m long. then the height of the water change when the water is 4 m deep is 1/8 m/min

The depth of the water is 4/5 of the depth of the trough, so the width of the surface will be 4/5 of the width of the trough:

 4/5 × 2 m = 8/5 m

Then the surface area of the water is ...

 Area = LW = (10 m)(8/5 m) = 16 m²

The rate of change of height multiplied by the area gives the rate of change of volume:

 2 m³/min = (16 m²)(h')

Identify the x-intercept and y-intercept for the equation 10x+5y=30

Answers

Considering the definition of a line, x-intercept and y-intercept, the  x-intercept and y-intercept are (3, 0) and (0,6) respectively.

Linear equation

A linear equation o line can be expressed in the form y = mx + b

where

x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

y-intercept and x-intercept

The point [y-intercept] is where the line crosses the y-axis, and occurs when x = 0.

The point [x-intercept] is that value of x for which the expression is equal to 0 and the line crosses the x-axis.

y-intercept and x-intercept in this case

In this case, the line is 10x +5y=30. Expressed in the form y = mx + b, you get:

5y= 30 - 10x

y= (-10x + 30)÷5

y= -10/5x + 30/5

y= -2x +6

where:

m= -2b= 6

The point [y-intercept] is represented by the value of the y-intercept b. So the point [y-intercept] is (0,6).

Being the point [intersection x] that value of x for which the expression is equal to 0 or y is equal to 0, in this case it is calculated as:

0= -2x + 6

-6= -2x

(-6)÷ (-2)= x

3=x

Finally, the point [x-intercept] is (3,0).

The value of x is 18 and the value of ∠A (interior angle) is 73°.

According to the given figure,

We have:

∠A = 6x-35°

∠B = 3x+53°

The two parallel lines have been cut by another line.

(Note that when a line divides two parallel lines then the sum of the interior angles on the same side is 180° and the alternate interior angles are equal to each other.)

So, we will have the following expression:

∠A + ∠B = 180°

(6x-35+3x+53)° = 180°

9x+18 = 180

9x = 180-18

9x = 162

x = 162/9

x = 18

Now, putting the value of x in ∠A,

∠A = 6x-35°

∠A = (6*18-35)°

∠A = (108-35)°

∠A = 73°

Hence, the value of x is 18 and the measurement of ∠A is 73°.

Nikki’s car holds more gasoline, but Jillian’s car gets better gas mileage.

Answers

The statement that is best supported by the graph is; Jillian's car holds more gasoline, but Nikki's car gets better gas mileage.

How to Interpret Linear Graphs?

The total amount of gasoline each car tank can hold is shown on the left of each graph on the y-axis.

Jillian's car holds 22 gallons.

Nikki's car holds 20 gallons.

Jillian's car holds more gasoline.

Now we need to see which car gets better gas mileage. Getting better gas mileage means you can go farther with each gallon of gas.

With Jillian's car, after using 22 gallons of gas, you have gone 350 miles, and the gas tank is empty.

350 miles with 22 gallons is 350/22 = 15.9 miles per gallon.

With Nikki's car, you start with only 20 gallons. By the time you drive 350 miles, you still have some gas left. Not only did you start with less gas, 20 gal vs. 22 gal, but after driving the same distance, 350 miles, there is still some gas left in the tank, 6 gallons.

That means Nikki's car used 20 - 6 = 14 gallons to drive 350 miles. 350/14 = 25 miles per gallon.

The more miles per gallon you get, the better the mileage. Thus;

25 miles per gallon is better mileage than 15.9 miles per gallon.

Nikki's car has a smaller gas tank, but it gets better mileage.

The expression 8 ( 3x - 7 ) when expanded gives 24xx - 56.

The cornerstone of mathematics is the theory of operations; we use it to compute and remember fundamental truths. The subsequent three characteristics are applied to addition and multiplication: Commutative Property, Associative Property, and Distributive Property.

The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.

Consider the expression 8( 3x - 7 ),

Let's say y is equal to 8( 3x - 7 ).

By using the distributive property:

y = 8 × 3x - 8 × 7

y = 24x - 56

Find a relation between x and y such that the point (x, y) is equidistant from the point (2, -5) and (-2,9).​

Answers

Answer:

(0,2)

Step-by-step explanation:

x  = [tex]\frac{2-2}{2}[/tex] = [tex]\frac{0}{2}[/tex] = 0  We are finding the average of the x values (2 and -2)

y = [tex]\frac{-5+9}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2  we are finding the average of the y values (-5 and 9)

The relation between x and y such that the point (x, y) is equidistant from point(2, -5) and(-2, 9) = 2x + 7y = -14

Points (2, -5) and (-2, 9).

let (x, y) be A

Let (2, -5) = (-2, 9) = B

Ax = Bx (length)

Squaring on both sides

Ax² = Bx²

By distance formula

(x - 2)² + (y +5)² = (x + 2)² + (y - 9)²

x² - 4x + 4 + y² +10y + 25 = x² + 4x + 4 + y² - 18y + 81

8x + 28y = -56

by multiplying both sides by 4

2x + 7y = -14

Assume that a new lithium isotope, 8Li, is identified. It is a trace isotope, meaning that it exists in a very tiny quantity. How will this discovery affect the atomic mass of lithium?

Answers

Since the isotope has only a very little amount in nature, it does not largely affect the  atomic mass of lithium.

What is an isotope?

The term isotope has to do with the atoms of the same element that do have the same atomic number but different mass numbers. The implication of this is that isotopes have the same number of protons but do not have the same number of neutrons.

Note that the average atomic mass of an atom is the weighted average of the atomic masses of all the isotopes of the compound. The isotopes that contribute greatly towards the atomic mass are those that have a larger percentage abundance.

Given that the new lithium isotope, 8Li identified  is a trace isotope, meaning that it exists in a very tiny quantity, it does not any noticeable effect on the  atomic mass of lithium.

Good Diet, Proper Exercise Help Protect Astronauts' Bonesby Bill Jeffs1 Eating right and exercising hard in space helps protect International Space Station astronauts bones, a finding that may help solve one of the key problems facing future explorers heading beyond low Earth orbit.2 A study, published in the September 2012 issue of the Journal of Bone and Mineral Research, looked at the mineral density of specific bones as well as the entire skeleton of astronauts who used a new, stronger "weight lifting" machine. Of course, weights don't really "weigh" anything on the space station but resistance machines allow astronauts to get the same kind of workout. The Advanced Resistive Exercise Device (ARED), installed in 2008, doubles the maximum simulated weight to as much as 600 pounds.3 Researchers compared measurements from 2006 until 2008, when astronauts used a less capable workout machine. They found that astronauts using the advanced system came home with more lean muscle and less fat, and kept more of their whole body and regional bone mineral density. Those same astronauts also consumed sufficient calories and vitamin D, among other nutrients. These factors are known to support bone health and likely played a contributing role.4 "After 51 years of human spaceflight, these data mark the first significant progress in protecting bone through diet and exercise," said Dr. Scott M. Smith, NASA nutritionist at the agency's Johnson Space Center in Houston and lead author of the publication.5 Since the 1990s, resistance exercise has been thought to be a key method of protecting astronauts' bones. Normal, healthy bone constantly breaks down and renews itself, a process called remodeling. As long as these processes are in balance, bone mass and density stay the same. Earlier studies of Russian Mir space station residents found an increased rate of breakdown, but little change in the rate of regrowth, resulting in an overall loss in bone density.6 In the study, astronauts who used the ARED device still had increased bone breakdown, but their bone renewal tended to increase, likely resulting in a better balance in whole bone mineral density.7 "The increase in both bone breakdown and formation suggests that the bone is being remodeled, but a key question remains as to whether this remodeled bone is as strong as the bone before flight," said Dr. Jean Sibonga, NASA bone discipline lead at Johnson and coauthor of the study.8 Bone density loss in astronauts on long-duration missions has been a major medical concern. In the past, astronauts have lost an average of 1 to 2 percent per month. By comparison, an elderly person loses about 1 to 2 percent per year.9 This study shows that, through proper exercise and nutrition, crew members on long journeys in space can return to Earth with much less loss of bone mineral density. But a key question remains as to whether the bones are as strong as when the astronaut launched into space. For these and other reasons, additional studies to evaluate bone strength before and after flight are currently under way.10 Beyond bone strength, further study is needed to figure out the best possible combination of exercise and diet for long-duration crews. One experiment on the space station right now is looking at how different ratios of animal protein and potassium in the diet affect bone health. Another is looking at the benefits of lowering sodium intake. NASA food scientists have reformulated more than 80 space foods to reduce the sodium content.11 "Although more research needs to be done in this regard, our study marks a significant milestone in our long search to find ways to help ensure crew health and performance on long-duration missions," said Smith. "These data will be critical in enabling us to send humans, once again, to destinations beyond low Earth orbit." Ann, Ben, and Cindy were eating strawberries.
