Answer:
40,608,000 km or 4.0608×[tex]10^{7}[/tex] km
Step-by-step explanation:
Speed(km/h) = Distance(km)/Time(Hours)
Distance = Speed × Time
6 days = 24 × 6 = 144 hours
282,000 km/h × 144 hours = 40,608,000 km

Answer:
x < 3/14
Step-by-step explanation:
-14x > -3
divide each side by -14
however, whenever multiplying or dividing an inequality by a negative value then you must reverse the inequality symbol
x < 3/14
Answer:
divide by -14:
[tex]x<3/14[/tex]
when you divide by a negative the sign flips
Andrew collects stamps. He collected a total of 150 stamps. If 68% of the stamps he collected were foreign, how many other stamps did he collect?
answer is 48 stamps
explanation is 150 times 68% is 102 stamps then that means there would be 48 other stamps.
Which value of x is in the domain of f(t) = squared x - 7
O A. x= 8
O B. x = 0
C. x= -3
O D. x = 6
SUBMIT
Given:
The given function is:
[tex]f(x)=\sqrt{x-7}[/tex]
To find:
The value of x that is in the domain.
Solution:
Domain is the set of input values.
We have,
[tex]f(x)=\sqrt{x-7}[/tex]
We know that the square root is defined for non negative values. So,
[tex]x-7\geq 0[/tex]
[tex]x\geq 0+7[/tex]
[tex]x\geq 7[/tex]
Thus, the domain of the given function is all real number that are greater than or equal to 7.
In the given options 0, -3, 6 are less than 7 but 8 in option A is the only value that is greater than 7. So, [tex]x=8[/tex] is in the domain of the given function.
Therefore, the correct option is A.

Evaluate 32 + (7 − 2) ⋅ 4 − 6 over 3 . (1 point)
Answer:
50
Step-by-step explanation:
Given:
32 + (7 − 2) ⋅ 4 − 6/3
Using the acronym PEMDAS
P = parenthesis
E = Exponential
M = Multiplication
D = Division
A = Addition
S = Subtraction
32 + (7 − 2) ⋅ 4 − 6/3
= 32 + (5) • 4 - 6/3
= 32 + 20 - 6/3
= 32 + 20 - 2
= 52 - 2
= 50
Therefore,
32 + (7 − 2) ⋅ 4 − 6/3 = 50
First round 7.35 to the nearest one.

The cost of having a window fixed is $100 plus $20 per hour of labor. Using h for the number of hours of labor, write an expression that represents the total cost.
Answer: 100+20h=x
Step-by-step explanation:
100 for the cost of the window Plus $20 times amount of hours the person does i equal the total amount you want to get which is x
Answer:
100 + (20 x H)
Step-by-step explanation:
100 dollars plus the amount paid for each hour of labor, so it would be 20 x H. Altogether it should be 100 + (20 x H).
Hope I helped!
The cost to play the game is $2. The winner gets $6 for making green. Suppose 36 people play the game. How much money will the school take in from this game before giving out prize money? *
Answer:
$72
Step-by-step explanation:
I did 36 x 2. I did not subtract the -6 for the prize money because it says not to.
Answer:
$72
Step-by-step explanation:
You are trying to determine how much money the school will take in before giving out prize money. Knowing this, you can actually ignore the $6 that the winner will get because you are not worried about giving out the prize money yet. You are only worried about how much you will make before the prize money.
So, you can do simple multiplication to find the answer:
price per game * amount of people playing game = money made from games
$2 * 36 = x
$72 = x

If the sum of the squares of the two legs of a triangle does not equal the square of the third side, what can you conclude?
Answer:
The triangle is not right angled.
Step-by-step explanation:
According to the Pythagoras theorem, the sum of the squares of the two legs of a triangle is equal the square of the third side.
For example, in triangle ABC,
[tex]AB^{2} = BC^{2}+CA^{2}[/tex]
It shows, that the triangle ANBC is right angled and right angle is at C.
So if the sum of the squares of the two legs of a triangle does not equal the square of the third side, it shows that the triangle is not right angled.

Select the ratio that represents sin(x)
A) 21/29
B) 29/21
C) 20/29
D) 20/21
E) 29/20
F) 21/20

17, 40, 23, 44, 44, 30
Answer:
35
Step-by-step explanation:
Organize the data from least to greatest
17, 23, 30, 40, 44, 44
Move to the middle
which is 30 and 40
Add 30 and 40 which is 70
divide 70 by 2 which is 35
So the median is 35

f(x) = 3x - 1 and g(x) = x + 2, find (f+9)(x).
Answer:
what is this it looks so hard I don't have the answer
Answer:
(f + g)(x) = 4x + 1
Step-by-step explanation:
f(x) = 3x - 1
g(x) = x + 2
(f + g)(x) = f(x ) + g(x)
= 3x - 1 + x + 2
= 4x + 1
1. Provide an example of a variable term.
2. Provide an example of a constant term.
3. When looking at an expression and/or equation, how can we tell that we need to distribute?
4. When solving an equation, if you get the solution, x=0, how many solutions to the equation are there?
(One solution, no solution, or infinite solutions)
5. When solving an equation, if you get 5 = 11, what does this mean? (One solution, no solution, or infinite
solutions)
6. When solving an equation, if you get 5 = 5, what does this mean? (One solution, no solution, or infinite
solutions)
Answer:
Step-by-step explanation:
1) a variable term contains a variable. If x is a variable
5x is an example of a variable therm
2) a constant therm is not a variable
3 is an example
3) for example when a number multiply a sum or a difference between a constant and a variable
Example:
2(x-3) = 5(x+4)
4) one solution: only if x is equal to 0 the equation is true
5) no solution: the equation can’t be true for ever value of the variable
6) infinite solutions: the equation is ever true for every value of the variable
