Answer:
(2 x 100) + (6 x 10) + (804 x 10^-3)
Step-by-step explanation:
The figure located at the hundred must be multiplied by 100
The figure located at the tens must be multiplied by 10
The figure located at the ones must be multiplied by 1
The figure located at the tenth must be multiplied by 10^-1
The figure located at the hundredth must be multiplied by 10^-2
The figure located at the thousandths must be multiplied by 10^-3
All the previous expression must be added. Then, 2 hundreds, 6 tens, and 804 thousandths is the same as:
(2 x 100) + (6 x 10) + (804 x 10^-3) = 260.804

PLZ HELP! WORTH EXTRA POINTS!! PYTHAGREOM THEROEM WITH 3D SHAPES
Answer:
16 units
Step-by-step explanation:
Using the Pythagorean theorem, we can find 1/2 the length of b. We will call it x
15^2 + (x)^2 = 17^2
225 + x^2= 289
Subtract 225 from each side
x^2 = 289-225
x^2 =64
Take the square root of each side
sqrt(x^2) = sqrt(64)
x =8
This is one half the length of b
b= 2*8
b = 16
Answer:
16
Step-by-step explanation:
17² = 15² + (b/2)²
64 = (b/2)²
b/2 = 8
b = 16

D(1) =3
D(n) = d(n-1)-14
Answer:
D(1)=3
Step-by-step explanation:
Answer:
The 3rd term is -25
Step-by-step explanation:
This is a recursive formula. It tells us that the first term is 3 and that the common difference is -14.
d(1)=3
d(2) = d(1) -14 = -11
d(3) = d(2) - 14 = -25
The 3rd term is -25
What is the radius of the circle given by the equation below?
x2 + 12x + y2 - 12y = -56
A. 2
B. 16
C. 4
D. 8
Answer:
C
Step-by-step explanation:
First, you gotta complete the square!
x^2+12x+36 = (x+6)^2
y^2-12y+36 = (y-6)^2
So, we have (x+12)^2 + (y-6)^2 = -56 + 36 + 36
The right side of the equation is the radius^2.
Simplify:
-56 + 36 + 36 = 16
The square root of 16 is 4, so the answer is C!

Answer:
[tex]x+3[/tex] if [tex]x>2[/tex]
Step-by-step explanation:
Recall some following basic ideas about absolute value:
[tex]|0|=0[/tex] or I guess [tex]-(0)=0[/tex]
[tex]|3|=3[/tex]
[tex]|-3|=-(-3)[/tex] or just [tex]3[/tex] but there is a reason why I wrote it the way I did.
You see that the absolute value returned the same value if the value was positive.
You see that the absolute value returned the opposite value if the value was negative.
You can include 0 in either.
Let's look at [tex]|x+3|[/tex] alone for a second.
*[tex]|x+3|=x+3[/tex] if [tex]x+3[/tex] is positive or zero.
When is [tex]x+3[/tex] positive or zero? [greater than or equal to 0]
[tex]x+3\ge 0[/tex]
Subtract 3 on both sides
[tex]x\ge -3[/tex]
*[tex]|x+3|=-(x+3)[/tex] if [tex]x+3[/tex] is negative or zero.
When is [tex]x+3[/tex] negative or zero? [less or equal to 0]
[tex]x+3\le 0[/tex]
Subtract 3 on both sides
[tex]x\le -3[/tex]
So looking at the bullet points (the *), [tex]x>2[/tex] fits into the first inequality.
Therefore, [tex]|x+3|=x+3[/tex].

A sports franchise would like to increase their Instagram followers by 25%. This means they would need 300,000
more followers. How many followers do they currently have?
a) 75,000
b) 300,000
c) 525,000
d) 1,200,000
Answer:
D. 1,200,000
Step-by-step explanation:
25%=0.25 which if multiplied by 4 = 1 which is the current followers. 300,000 multiplied by 4 = 1,200,000
Using percentages we know that the current followers of the sports franchise are (D) 1,200,000.
What are percentages?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it. By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.So, the current followers are:
Let the correct followers be x.Now calculate as follows:
x/100 × 25 = 300,00025x = 30,000,000x = 30,000,000/25x = 1,200,000Therefore, using percentages we know that the current followers of the sports franchise are (D) 1,200,000.

Step-by-step explanation:
A lomy owner has his own fuel supply and needs to refill his storage tank. He has just completely
filled the fuel tank of the lorry with 170 litres from empty. He now has 100 litres of fuel left in his
storage tank. With the price of fuel expected to fall soon he only wants to buy enough for the next
fortnight. Normally his regular short daily trips total 300 km and this leaves just 20 litres in the
lorry's fuel tank. He expects to complete three regular days of 300 km journeys each week, but
this could rise to five. Sometimes the total journeys are longer but his daily trips never total more
than 400 km in a day. He never works more than five days in a week. His storage container holds
4000 litres
How much fuel should he order to be certain that he has enough for the next two weeks?
Answer: He should order for 1046.67 litres fuel to be certain that he has enough for the next two weeks
Step-by-step explanation:
Note that he has just completely
filled the fuel tank of the lorry with 170 litres from empty. He now has 100 litres of fuel left in his storage tank
If his regular short daily trips total 300 km and this leaves just 20 litres in the lorry's fuel tank.
That is 100 litres -20 litres = 80 litres
On 300km, he consumed 80 litres
He plans to complete three regular days of 300 km journeys each week, but this could rise to five. Sometimes the total journeys are longer but his daily trips never total more than 400 km in a day. He never works more than five days in a week. His storage container holds
4000 litres
From all these analysis, we can deduce that the maximum km of journey he should prepare for is
400km × 5 = 2000km for one week
Since he consumed 80 litres of fuel for any 300km
Then,
80/300 = L/2000
L = 1600/3
L = 533.33 litres
The journey for two weeks will be
533.33 × 2 = 1066.67 litres
Recall that he left 20 litres in the tank. Take this away from 1066.67 litres.
1066.67 - 20 = 1046.67 litres
He should therefore order for 1046.67 litres fuel to be certain that he has enough for the next two weeks

One month Donna rented 5 movies and 6 video games for a total of $48. The next month she rented 3 movies and 2 video games for a total of $18. Find the
rental cost for each movie and each video game.
Rental cost for each movie: s]
x
5
?
Rental cost for each video game: S
Answer:
Cost for each movie: $1.50 Cost for each video game: $6.75
Step-by-step explanation:
Let x be the cost (in dollars) of renting a movie.
Let y be the cost (in dollars) of renting a video game.
The total cost of renting 3 movies and 2 video games is +3x2y dollars.
We're given that this total cost is $18, so we have =+3x2y18.
The total cost of renting 5 movies and 6 video games is +5x6y dollars.
We're given that this total cost is $48, so we have =+5x6y48.
Therefore, we get the following system of equations.
=+3x2y18
=+5x6y48
Multiplying the first equation by −3 and adding gives us the following.
−9 x− 6 y = −54 5 x+ 6 y = 48 −4 x+ 0 y = −6
So we get the equation =−4x−6.
Solving for x, we get the following.
=x1.5
To find y, we can substitute 1.5 for x in =+3x2y18, the first equation in the system.
Then we solve for y.
+31.52y =18
+4.52y =18
2y =13.5
y =6.75
So, we have found that =x1.5 and =y6.75.
This means that the rental cost for each movie is $1.50 and the rental cost for each video game is $6.75.

What is the solution of the following system?
y=-x+2
y=-4x – 1
Your answer
Answer:
y = 3
x = -1
Step-by-step explanation:
The idea to start the problem is that we need to cancel x in one equation to find y first, therefore:
y = -x + 2 (let's multiply this entire equation by -4)
y = -4x - 1
We then have .:
- 4y = 4x - 8
y = -4x - 1 (now we sum both equations)
.:
- 3y = -9 (isolate y)
y = -9 / -3
y = 3 (good we have y!)
Now come back to one of the equations, substitute y to find your x!
Substituting on the first equation we have:
3 = -x +2 (isolate x)
3 - 2 = -x
1 = -x (multiply everything by -1)
x = -1

If each score in a set of data scores were increased by 8 points:
The mean would increase by 8, and the standard deviation would remain the same.
Option C is the correct answer.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
Mean is the sum of all the values divided by the number of the values.
Example:
1, 2, 3, 4, 5
Mean = (1 + 2 + 3 + 4 + 5) / 5
Mean = 15/5 = 3
Now,
If 1 is increased in each set,
Mean = (2 + 3 + 4 + 5 + 6) / 5
Mean = 20/5 = 4
We see that,
3 + 1 = 4
So,
The Mean is increased by the number we add with each number.
Now,
The standard deviation shows how the values are spread so,
Increasing each number will not change the standard deviation.
Thus,
The mean would increase by 8, and the standard deviation would remain the same.

How will the graph of line y = -3x+8 be affected if the 8 is changed to -3?
A. The y-intercept will be moved 3 units downward.
B. The y-intercept will be moved 5 units downward.
C. The y-intercept will be moved 11 units downward.
D. The x-intercept will be moved 3 units to the left.
E. The x-intercept will be moved 11 units to the left.
Answer:
C
Step-by-step explanation:
A y intercept lies on the y axis.
This means that the movement will happen with the y intercept, on the y axis.
8 is the original y intercept.
It is now changed to -3.
-3 is lower than 8 on the y axis so we are moving downward.
Now, to find the number of squares it moves, we can find the difference between 8 and -3.
8-(-3)=11
Therefore, The y-intercept will be moved 11 units downward.
Answer:
C.
Step-by-step explanation:
The -3x tells you the slope (rise/run). In this case, it will go downward because it is negative. It will have a slope of 3/1. The +8 or -3 is the y intercept and tells which direction the original line will go from its' starting point. So you would add those together to know which way the line moves.
