Andre says that 1/4 is less than -3/4 because, of the two numbers, 1/4 is closer to 0. Do you agree? Explain your reasoning.
Answer:
Andre is wrong
Step-by-step explanation:
Andre is wrong because 1/4 is a positive number and -3/4 is a negative number so that makes Andre wrong for that, but if it is who is closer to 0 then Andre is right because when you look at it on a table you can see that 1/4 is closer.
In this number tree, the integers greater than or equal to 0 are written out in increasing order, with the top row containing one integer and every row after containing twice as many integers as the row above it. If row 1 contains the integer 0, what is the fifth number in row 10?
Answer:
The fifth integer in row 10 using the number tree pattern is 515.
Step-by-step explanation:
The attached picture is instrumental to understanding the solution to this. There are different methods to approach this problem. But we will use observations to solve the problem.
Looking at the tree diagram, we see that the first row has 1 integer, the second has 2, the third has 4 and the fourth has 8. From here, we can see that a row has 2^n numbers where n = 0, 1, 2, 3, 4, . . .
Row 1 = 2^0 = 1 number
Row 2 = 2^1 = 2 numbers
Row 3 = 2^2 = 4 numbers
Row 4 = 2^3 = 8 numbers. And so on.
Also we notice that the last number in row 4 is 14. This can be gotten by adding the total number of numbers from row 1 to row 4 which is
1 + 2 + 4 + 8 = 15 but the first number on the chart is 0 which means we have to take out the first integer to get the last integer on row 4. Doing this, we have 14.
Since our aim is to know the fifth number in row 10, then we need to know the last number in row 9 then count from the first number in row 10 to the fifth. Using 2^n to get the number of numbers in each row like we've done above we can add the number of numbers to know the total numbers we have from row 1 to row 9 as follows:
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 = 511
As we've said previously, 0 is the first integer in the tree and should be removed to know the last number in row 9. This would be 510.
If 510 is the last number in row 9 is 510, then the first number in row 10 would be 511. Counting to the fifth number we get to 515. Thus the fifth number in row 10 using the number tree pattern is 515.
The system shown is _____.
A.) consistent
B.) inconsistent
C.) equivalent
Answer:
The system shown is consistent ⇒ A
Step-by-step explanation:
A consistent system of equations has at least one solution
The consistent independent system has exactly 1 solutionThe consistent dependent system has infinitely many solutionsAn inconsistent system has no solution
In the system of equations ax + by = c and dx + ey = f, if
a = d, b = e, and c = f, then the system is consistent dependent and has infinitely many solutionsa = d, b = e, and c ≠ f, then the system is inconsistent and has no solutiona ≠ d, and/or b ≠ e, and/or c ≠ f, and [tex]\frac{a}{d}[/tex] ≠ [tex]\frac{b}{e}[/tex] , then the system is consistent independent and has exactly one solutionFrom the given graph
∵ The two lines intersected at one point
∴ This point lies on the two lines
→ That means this point satisfies the equations of the lines
∴ The system of equations represented by the two lines has 1 solution
→ By using rule 3 above
∴ The system shown is consistent

An angle measures 8.2° more than the measure of its complementary angle. What is the
measure of each angle?
9514 1404 393
Answer:
49.1°, 40.9°
Step-by-step explanation:
Let x represent the smaller angle. Then the larger is x+8.2 and the total of the two angles is ...
x + (x +8.2) = 90
2x +8.2 = 90 . . . . . collect terms
x + 4.1 = 45 . . . . . . .divide by 2
x = 40.9
x +8.2 = 49.1
The two angles are 49.1° and 40.9°.

The nth term of a quadratic sequence is an² + bn where a and b are integers. The second term of the sequence is 8, and the fifth term is 65. What is the value of the tenth term in the sequence?
Step-by-step explanation:
When n = 2,
(2)²a + (2)b = 8.
=> 4a + 2b = 8.
When n = 5,
(5)²a + (5)b = 65.
=> 25a + 5b = 65.
4a + 2b = 8. => 10a + 5b = 20
25a + 5b = 65
- (10a + 5b = 20)
=> 15a = 45, a = 3.
Therefore 4(3) + 2b = 8, 2b = -4, b = -2.
We have a = 3 and b = -2.
Hence when n = 10,
an² + bn
= (10)²(3) + (10)(-2)
= 300 - 20
= 280.
The 10th term of the sequence is 280.
Answer:
The 10th term of the sequence is 280
Step-by-step explanation:
When n = 2,
(2)²a + (2)b = 8.
=> 4a + 2b = 8.
When n = 5,
(5)²a + (5)b = 65.
=> 25a + 5b = 65.
4a + 2b = 8. => 10a + 5b = 20
25a + 5b = 65
- (10a + 5b = 20)
=> 15a = 45, a = 3.
Therefore 4(3) + 2b = 8, 2b = -4, b = -2.
We have a = 3 and b = -2.
Hence when n = 10,
an² + bn
= (10)²(3) + (10)(-2)
= 300 - 20
= 280.

Answer:
x = 16
k = 145 degrees
Step-by-step explanation:
We can see that the polygon is 7 sided
The sum of the internal angles will
be:
(n-2)180: (7-2) * 180 = 900
By adding all internal angles, we get 900
5x + 10x + 9x + 1 + 9x - 14 + 9x + 1 + 10x + 5x = 900
57x -12 = 900
57x = 912
x = 912/57
x = 16
The side marked k
is 9x + 1
= 9(16) + 1 = 145 degrees

Sara sold 461 tickets for a school play. Student tickets cost $3 and adult tickets cost $4. Sara’s sales totaled $1624.How many adult tickets and how many student tickets did Sara sell?
Answer:
220 student and 241 adults
Step-by-step explanation:
x+y=461
3x+4y=1624
y=-x+461-----> 3x+4(-x+461)=1624
-x+1844=1624
+x -1624
x=220
3(220)+4y=1624
660+4y=1624
4y=964
y=241
There are 241 adult tickets and 220 student tickets did Sara sell.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Sara sold 461 tickets for a school play.
And, Student tickets cost $3 and adult tickets cost $4. Sara’s sales totaled $1624.
Let number of adult tickets = x
And, Number of student tickets = y
Hence, We get;
⇒ x + y = 461 .. (i)
And, 4x + 3y = 1624 .. (i)
Multiply by 3 in (i);
⇒ 3x + 3y = 1383 .. (iii)
Subtract form (ii);
⇒ x = 241
And, From (i);
⇒ x + y = 461
⇒ 241 + y = 461
⇒ y = 461 - 241
⇒ y = 220
Thus, There are 241 adult tickets and 220 student tickets did Sara sell.

Solve for x. √10x+50=x+5
x = 5 or x = 10
x = 0 or x = 5
x = 0 or x=−5
x = 5 or x=−5
Answer:
x = 5 or x = -5
Step-by-step explanation:
I took the k12 quiz
The solutions are x = 5 and x = -5 for the given equation √10x+50=x+5.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To solve for x in the equation √(10x+50) = x+5, we can first isolate the radical term by squaring both sides:
(√(10x+50))²= (x+5)²
Simplifying the left side gives:
10x+50 = x² + 10x + 25
Combining like terms and moving all terms to one side, we get:
x² - 25 = 0
This is a quadratic equation that can be factored as:
(x-5)(x+5) = 0
Therefore, the solutions are x = 5 and x = -5 for the given equation √10x+50=x+5.

A boat traveled 240 miles downstream, then 240 miles back upstream. The trip downstream took 20 hours. The trip back upstream took 60 hours. Use this information to fill in the following blanks. Note: Express your answers as integers.
The speed of the boat in still water is [answer]
miles per hour.
The speed of the current is [answer]
miles per hour.
Answer:
it takes longer for the boat to get back because it's moving against the current. to see how fast the boat is moving, you divide the amount of miles traveled, by how long it took.
240/20 = 12
in still water the boat travels it's 12 miles per hour
240/ 60 = 4
against the current, the boat travels 4 miles per hour
if you need to find the speed of the current, you need to find the resistance that's going against the boat making it slow down. you do that by doing 12 - 4 = 8 miles per hour is the speed of the current.

How much punch did Susan make altogether? 3 cups seltzer water 1 gallon apple juice 4 pints lemonade
Answer:
Susan makes [tex]13\frac{1}{2}[/tex] pints of punch.
Step-by-step explanation:
Consider the provided information.
We know that:
2 cups (c) = 1 pint (pt)
4 cups (c) = 1 quart (qt)
16 cups (c) = 1 gallon (gal)
So 3 cups = [tex]1\frac{1}{2}[/tex] pint
1 gallon = 16 cups = 8 pint
The three mixed together would make [tex]1\frac{1}{2}+8+4=13\frac{1}{2}[/tex] pints of punch.
Hence, Susan makes [tex]13\frac{1}{2}[/tex] pints of punch.
