Answer:

2.14

Step-by-step explanation:

The solution to the inequality is 2 ≤ x < 8.

A mathematical inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

Here,

The mathematical inequality given is,

8 ≥ -5x + 2 > -38

Subtracting 2 from all sides,

-8 - 2 ≥ -5x + 2 - 2 > -38 - 2

So, -10 ≥ -5x > -40

Dividing by -5 on all sides,

Therefore,

2 ≤ x < 8

That means the inequality is reserved.

Hence,

The solution to the inequality is 2 ≤ x < 8.

The correct option is " They needed more reliable sources of food and supplies".

Neolithic is termed the stone period. This is so because this was the evolution of the prehistoric humans that developed and discovered many of the things that are made up of stones.

The people of this era domesticated both flora and fauna that means plants and animals as the forest was their inhabitants, plants were their food eatables and animals were the ones that they can hunt, play, tame, and sometimes can also have them in their meals. They were using plants and animals with various methods and types.

Therefore, the option  " They needed more reliable sources of food and supplies" is the correct answer.

Answer:

[tex]1)\ x = 5[/tex]

[tex]2)\ x = 14[/tex]

[tex]3) \ x = 15,\ y = 2[/tex]

Step-by-step explanation:

1) Given that M<1 = 95 + 7x and M<2 = 55 - x, you should look on the diagram to see what type of angles M<1 and M<2 are.

On the diagram at the top, angles 1 and 2 appear to be supplementary angles, meaning they add up to 180 degrees. You can apply this information to creating an equation:

Now you can solve this equation by combining like terms on the left-hand side of the equation.

Subtract 150 from both sides of the equation in order to isolate the variable x.

Divide both sides of the equation by 6 in order to isolate the variable x completely.

2) You are given that M<3 = 5x + 12 and M<4 = 7x - 16, so look on the diagram at the top to find out what type of angles they are.

Angles 3 and 4 appear to be alternate exterior angles, meaning that they are equal to each other as stated by the Alternate Exterior Angles Theorem. You can use this information to make an equation where M<3 = M<4.

Subtract 5x from both sides of the equation, and add 16 to both sides of the equation.

Divide both sides of the equation by 2 to isolate the variable x completely.

3) Given that M<1 = 7y + 16, M<2 = 2x, and M<3 = 4x - 30, look on the diagram at the bottom to find out what type of angles they are.

Since angles 2 and 3 include an "x" variable, you should start with them first  in order to be able to solve for x. Angles 2 and 3 are complementary angles, meaning that they are equal to each other based on the Complementary Angles Theorem. Translate this information into an equation:

Subtract 2x from both sides of the equation and add 30 to both sides of the equation.

Divide both sides of the equation by 2 in order to isolate the variable x completely.

Now to solve for y - based on the diagram, you can see that angle 1 and angle 2 are vertical angles, meaning that they are equal to each other based on the Vertical Angles Theorem.

You can make them equal to each other in an equation:

We solved for x and know that it is 15, so substitute 15 into the equation for x.

Subtract 16 from both sides of the equation.

Divide both sides of the equation by 7 to isolate the variable x.

Answer:

The volume of the actual​ tractor-trailer is 2992 in³

Step-by-step explanation:

To determine how many times the volume of the model is the volume of the actual​ tractor-trailer,

First, we will determine the volume of the model tractor-trailer.

Since, the model tractor trailer is shaped like a rectangular prism, the volume of the model tractor-trailer can be calculated using the formula for volume of a rectangular prism.

Volume of rectangular prism = length × width × height

From the question,

length = 11 in

width = 2 in

and height = 4 in

∴ Volume of model tractor-trailer = 11 in × 2 in × 4 in

Volume of model tractor-trailer = 88 in³  

From the question,

The scale of the model is 1 font size decreased by 10 : 34 font size decreased by 10.

That is 1 : 34

Then, if the the volume of the actual​ tractor-trailer is y, we can write that

[tex]\frac{1}{34} = \frac{88}{y}[/tex]

Then,

y = 88 × 34

y = 2992 in³

Hence, the volume of the actual​ tractor-trailer is 2992 in³.

Width of rink , W = 20 meters.

To Find :

How many meters of handrail does Gus need to cover the perimeter of the rectangular skating rink.

Solution :

We know, perimeter is given by :

[tex]P=2(L+W)[/tex]

Putting value of L = 40 meters and W = 20 meters, in above equation , we get:

[tex]P=2(40+20)\ meters\\\\P=120\ meters[/tex]

Therefore, the perimeter of the rectangular skating rink is 120 meters.

Hence, this is the required solution.

Answer: x = -9

Step-by-step explanation:

3x + 2x = 5x

7x + 5 - 5 = 5x - 13 - 5

Subtract 5 from both sides

7x + 5 - 5 = 5x - 13 - 5

simplify

7x = 5x - 18

Subtract 5x from both sides

7x - 5x = 5x -18 - 5x

simplify

2x = -18

divide both sides by 2

[tex]\frac{2x}{2}[/tex] = [tex]\frac{-18}{2}[/tex]

We multiply 6 times the sum of a number and 8

That is equal to 5

6*(x+8) = 5

Answer:

g = 6

Step-by-step explanation:

3.8g + 8 = 1.8g + 20

Subtract 1.8g from both sides;

2g + 8 = 20

Subtract 8 from both sides;

2g = 12

Divide both sides by 2;

g = 6

You can check if the value of g is correct by plugging in the value of g to the equation. If your check does not it doesn't mean your answer is not correct because sometimes it can be a no solution equation which means that there is no solution to the equation.

Check:

3.8(6) + 8 = 1.8(6) + 20

22.8 + 8 = 10.8 + 20

30.8 = 30.8

It means its correct

To get the best estimate of the square root of 90 we will apply a short cut.

Square root of 90 will be in the form of a mixed fraction as [tex]a\frac{b}{c}[/tex] or in decimals.

Here, a = square root of a perfect square number nearest to 90.

b = Difference of 90 and the perfect square number

c = Double of 'a'

Nearest square number to 90 = 81

Square root of 81 = 9

So, a = 9

Difference in 90 and 81 = 9

So, b = 90 - 81 = 9

And double of 9 = 18

Therefore, c = 18

Hence, [tex]\sqrt{90}\approx9\frac{9}{18}[/tex]

                    [tex]\approx9.5[/tex]

So the nearest number given in the option may be 9.4

Therefore, Option B will be the answer.

Iif two pounds of apples cost $3.98. Six pounds cost $11.94 then 2 pounds is the rate of change for the cost of apples

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Two pounds of apples cost $3.98

Six pounds cost $11.94.

We need to find the rate of change for the cost of apples

The cost changes from $ 3.98 to $ 11.94

while the number of pounds of apples changes from 2 to 6.

Thus the rate of change is

11.94-3.98/6-2

2 pounds

Hence, if two pounds of apples cost $3.98. Six pounds cost $11.94 then 2 pounds is the rate of change for the cost of apples
