Answer: X is less than or equal to 240

The solution to the inequality 0.75x - 100 ≤ 80 is x ≤ 240.

Given is an inequality what is 0.75x – 100 ≤ 80, we need to solve it,

To solve the inequality 0.75x - 100 ≤ 80, we can follow these steps:

1. First, let's isolate the variable x by adding 100 to both sides of the inequality:

0.75x - 100 + 100 ≤ 80 + 100

0.75x ≤ 180

2. Next, we can divide both sides of the inequality by 0.75 to solve for x:

(0.75x) / 0.75 ≤ 180 / 0.75

x ≤ 240

Therefore, any value of x that is less than or equal to 240 will satisfy the inequality.

Therefore, the solution to the inequality 0.75x - 100 ≤ 80 is x ≤ 240.

Answer:

A

Step-by-step explanation:

[tex]\sqrt{50}[/tex] is not a perfect square. This means that you can rule out answers B and D, because it won't be 'exactly' anything.

Let's think about the other answer choices. C says that the answer of \sqrt{50} will be between 24 and 25. This is easily checkable by doing [tex]24^{2}[/tex], which equals 576. This easily eliminates option C.

Now, if the other answer choices weren't so obviously incorrect, let's see how you would solve this. What's the closest perfect square root under 50?

[tex]\sqrt{49}[/tex], which equals 7.

What's the closest perfect square root above 50?

[tex]\sqrt{64}[/tex], which equals 8.

This puts [tex]\sqrt{50}[/tex] between 7 and 8.

Answer:

Option A

Step-by-step explanation:

Here we can find out the correct option by eliminating the wrong options . We know that √50 is not a perfect square.

This eliminates option d as it says that its value is exactly 7 .

[tex]\implies \red{\text{ Option D is wrong }}[/tex]

Now look at Option C , it says that it lies between 24 and 25 . This is impossible since , 24² = 576 and 25² = 625 .

[tex]\implies \red{\text{ Option C is wrong }}[/tex]

Again the option b is similar to option d , as it says its exact value is 25 which is not possible. Hence this option is also wrong .

[tex]\implies \red{\text{ Option B is wrong }}[/tex]

Now we are ultimately left with option with shared that its value lies between 7 and 8 . We know that 7² = 49 and 8² = 64. And 50 lies in between them. Therefore Option A is the correct option .

[tex]\implies \green{\text{ Option A is correct. }}[/tex]

The modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).

There are three laws, made by the Kepler, to explain the motion of the planet around the sun.

Earth’s rotation causes the rising and setting of the sun because of the earth's rotation on its axis.

this is very simple actually! i can teach you:

(x,y)

so if you are counting left or right it goes to the x. for example, if you want to find J, you go to the black dot that says J and count starting from 0 or by looking at the x axis.

if you are counting up or down you go to (input the value) the y. if you want to find J for example, (the y coordinate) you go to the black dot and you count starting from 0. usually it will have the points -5 -4 -3 -2 -1 0 1 2 3 4 5 but in your problem it does not have so you just have to count carefully.

i will go search for what K' or J' means

Total price =Rs920

Consider price without VAT as Rs x.

Then,

Total price =x+15%of x

or, 23x=920*20

or, x=18400/23

Therefore, x=Rs 800

to do what ?

the calculation of the 2 solutions for the quadratic equation is already done here.

so, what else do you need ? an explanation ?

in general, a quadratic equation looks like

ax² + bx + c = 0

and the formula for the solutions is

x = (-b ± sqrt(b² - 4ac))/(2a)

remember, a linear equation (x¹) has one zero solution.

a quadratic equation (x²) has 2 zero solutions.

a cubic equation (x³) has 3 zero solutions.

and so forth.

the 2 solutions here are created by the "±" operation. one solution is using the "+". and the other the "-". that is all.

so, what happened here was simply putting the values of the given equation into the solution formula and doing the calculations.

and the final line is saying that the solutions are the set of the 2 numbers represented by the "±" expression.

to finish this up for better clarity :

the first solution is

x = (-17 + sqrt(217))/4 = -0.567270034...

the second solution is

x = (-17 - sqrt(217))/4 = -7.932729966...

is there anything still unclear ? please let me know.

Answer:

maximum amount of number of days that Jackson can rent a car while staying with his budget is 2 days

Step-by-step explanation:

first of all find the amount of money he will spend for 500 miles

in this case we multiply 0.12 by 500

=> 0.12 × 500

=> 60

subtract 60 from the money budgeted which is $210

=> $210 - 60

=> 150

divide 150 by the company charges per day which is dollars 68.64

=> 150 ÷ 68.64

divide 150 by 68.64

=> 2.185314685314685

Answer:

m = 8

Step-by-step explanation:

first set the inside values equal to 90 degrees (6m + 6) + 36 = 90.

then easily work it out.

subtract 36 from each side

(6m + 6) + 36 = 90

               -36     -36

so now it's (6m + 6) = 54

subtract 6 from each side

6m = 48

divide each side by 6

m = 8
