Answer:
true
Step-by-step explanation:
A sixth-grade science club needs $180 to pay for the tickets to a science museum. All tickets cost the same amount. What could \large 180\div15 mean in this context? Describe two interpretations of the expression. Then, find the quotient and explain what it means in each interpretation. Your answer:
Answer:
Two interpretations:
1. Ticket price for each student
2. Number of students
Quotient = 12
Step-by-step explanation:
Given that:
Total money to be paid for the tickets to the science museum = $180
To find:
Two interpretations, what does the expression [tex]\large 180\div15[/tex] represent ?
Solution:
The expression [tex]\large 180\div15[/tex] has two terms:
1st is 180, which is the amount of money to be paid for the tickets to the science museum.
As price of all the tickets is same, 15 might be one of the two things:
1. Total Number of candidates:
If 15 is the total number of candidates, then the expression [tex]\large 180\div15[/tex] represents the price of each ticket.
2. Price of each ticket:
If 15 is the price of each ticket, then the expression [tex]\large 180\div15[/tex] represents the Total number of candidates.
Now, let us find the quotient:
[tex]\large 180\div15=\bold{12}[/tex]

Answer:
(x - y)(x + y + z)
Step-by-step explanation:
Given
x(x + z) - y(y + z) ← distribute both parenthesis
= x² + xz - y² - yz ← rearrange
= x² - y² + xz - yz ← x² - y² can be factored as a difference of squares

20 * 3/5 = 12 inusing the slope formula find the slope of the line that passes through these points (2,5) and (8,-3)
Answer:
-4/3
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
-3-5/8-2
-8/6
-4/3
Best of Luck!
Answer:
-4/3
Step-by-step explanation:
You can use rise/run. The rise (y values) goes from 5 to -3. You subtract 8 for this. The run (x values) goes from 2 to 8. You add 6 for this. the proportion is -8/6, which can be simplified to -4/3.
Therefore, the slope is -4/3!

In the arithmetic sequence 5,2,-1,-4 what term is -25?
Answer:
Thus, the eleventh term is -25.
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the sequence:
5,2,-1,-4,...
We can directly find the common difference by subtracting two successive terms:
r = 2 - 5 = -3
The same result is obtained by subtracting any pair of successive terms.
The first term is a1 = 5. The general equation is:
[tex]a_n=5-3(n-1)[/tex]
[tex]a_n=5-3n+3[/tex]
[tex]a_n=-3n+8[/tex]
We need to find which term is -25, thus:
-3n + 8 = -25
Subtracting 8:
-3n = -25 - 8 = -33
Dividing by -3:
n = -33 / (-3)
n = 11
Thus, the eleventh term is -25.

What is the equation of the line that is parallel to the given line and passes through the point (2, 3)?
Answer:
(-4,0)(4,-4)
slope(m) = (-4 - 0) / (4 - (-4) = -4/(4 + 4) = -4/8 = -1/2. A parallel line will have the same slope.
y = mx + b
slope(m) = -1/2
(2,3)...x = 2 and y = 3
now we sub and find b, the y int
3 = -1/2(2) + b
3 = -1 + b
3 + 1 = b
4 = b
y = -1/2x + 4
1/2x + y = 4....multiply by 2
x + 2y = 8 <== ur parallel line

Which are the solutions of the quadratic equation?
Answer:
The answer is C
Step-by-step explanation:
[Sin A + Sin 3A + Sin 5A + Sin 7A]÷
[Cos A + Cos 3A + Cos 5A + Cos 7A]
=Tan 4A
Do the following rewrites:
sin(x) = sin(4x - 3x) = sin(4x) cos(3x) - cos(4x) sin(3x)
sin(7x) = sin(4x + 3x) = sin(4x) cos(3x) + cos(4x) sin(3x)
sin(3x) = sin(4x - x) = sin(4x) cos(x) - cos(4x) sin(x)
sin(5x) = sin(4x + x) = sin(4x) cos(x) + cos(4x) sin(x)
cos(x) = cos(4x - 3x) = cos(4x) cos(3x) + sin(4x) sin(3x)
cos(7x) = cos(4x + 3x) = cos(4x) cos(3x) - sin(4x) sin(3x)
cos(3x) = cos(4x - x) = cos(4x) cos(x) + sin(4x) sin(x)
cos(5x) = cos(4x + x) = cos(4x) cos(x) - sin(4x) sin(x)
So in the numerator, we have
sin(x) + sin(3x) + sin(5x) + sin(7x)
= 2 sin(4x) cos(3x) + 2 sin(4x) cos(x)
= 2 sin(4x) (cos(3x) + cos(x))
In the denominator,
cos(x) + cos(3x) + cos(5x) + cos(7x)
= 2 cos(4x) cos(3x) + 2 cos(4x) cos(x)
= 2 cos(4x) (cos(3x) + cos(x))
So we have
(sin(x) + sin(3x) + sin(5x) + sin(7x)) / (cos(x) + cos(3x) + cos(5x) + cos(7x))
= (2 sin(4x) (cos(3x) + cos(x))) / (2 cos(4x) (cos(3x) + cos(x)))
= sin(4x) / cos(4x)
= tan(4x)

Find the sum or difference.
(- 2h + 1) + 2(3h - 4) SHOW YOU WORK FOR POINTS AND BRAINIEST
Answer: (- 2h + 1) + 2(3h - 4) = 4h -7
Step-by-step explanation:
First, remove unnecessary parentheses
- 2h + 1 + 2(3h - 4)
then distribute 2 through the parentheses
- 2h + 1 + 2(3h - 4) = -2h + 1 + 6h -8
Combine like terms
-2h + 1 + 6h -8 = 4h + 1 - 8
1-8= 7
So the answer is
4h - 7
AXYZ is in Quadrant 1. It is rotated 90° counterclockwise around the origin.
Then AX'Y'Z' is reflected across the y-axis. Then AX"Y"Z" is translated 5 units to
the right. In which Quadrant is AX"Y"" Z"'? How do you know?
Answer:
Quad 1
Step-by-step explanation:
AXYZ is in the 2nd quad bc of the rotation, then goes back to 1st quad bc of reflection (y axis). After this, the translation doesn't affect the movement of quadrants. A""X""Y""Z"' lands in quadrant 1.
Answer:
1st quadrant
Step-by-step explanation:
1. Rotated 90° counterclockwise from the 1st quadrant, moves object to the second quadrant.
2. Reflection across y-axis, moves object back to the 1st quadrant.
3. Translation to the right is moving to the right inside the 1st quadrant.

Step-by-step explanation:
Exact form = 10/3
Decimal form = 3.3
Mixed number form = 3 1/3
the solution for x is x = 10/3 or approximately x = 3.33.
To solve for x in the equation 8x - 2 - 5x = 8, we need to simplify and combine like terms, then isolate x on one side of the equation.
Let's start by combining the x terms on the left side:
(8x - 5x) - 2 = 8
Simplifying further:
3x - 2 = 8
Next, we want to isolate the x term. We can do this by adding 2 to both sides of the equation:
3x - 2 + 2 = 8 + 2
Simplifying the equation:
3x = 10
Finally, to solve for x, we divide both sides of the equation by 3:
(3x) / 3 = 10 / 3
The division yields:
x = 10/3
Therefore, the solution for x is x = 10/3 or approximately x = 3.33.

The amount of fertilizer needed for a lawn varies directly with the area of the lawn Mr. Dundee lawn is a rectangular shape and measures 78' x 93' 4 pounds of fertilizer are needed for 750 ft.² of lawn how much is needed for Mr. Dundees lawn to the nearest whole pound
Answer:
39 pounds is needed
Step-by-step explanation:
Given
Lawn Dimension: 78' by 93'
4 pounds fertilizer for 750ft² area
Required
Determine the amount needed for the given dimension
First, we need to calculate the area of the lawn
[tex]Area = 78' * 93'[/tex]
' means feet
So:
[tex]Area = 78ft * 93ft[/tex]
[tex]Area = 7254 ft^2[/tex]
Let the amount of fertilizer need be x
So, we have:
4 pounds = 750ft²
and
x = 7254ft²
Cross Multiply:
[tex]x * 750 = 4 * 7254[/tex]
[tex]x * 750 = 29016[/tex]
Solve for x
[tex]x = 29016/750[/tex]
[tex]x = 38.688[/tex]
[tex]x = 39[/tex] (approximated)

whats the slope intercept form for the points [5,2] and [0,-1]
Answer:
[tex]\displaystyle y=\frac{3}{5}x-1[/tex]
Step-by-step explanation:
The Equation of a Line
The equation of the line in slope-intercept form is:
[tex]y=mx+b[/tex]
Where m is the slope and b the y-intercept.
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
We are given the points (5,2) and (0,-1), thus:
[tex]\displaystyle y-2=\frac{-1-2}{0-5}(x-5)[/tex]
Operating:
[tex]\displaystyle y-2=\frac{-3}{-5}(x-5)[/tex]
[tex]\displaystyle y-2=\frac{3}{5}(x-5)[/tex]
To find the slope-intercept form, we continue to simplify the expression:
Removing the parentheses:
[tex]\displaystyle y-2=\frac{3}{5}x-\frac{3}{5}\cdot 5[/tex]
[tex]\displaystyle y-2=\frac{3}{5}x-3[/tex]
Adding 2:
[tex]\displaystyle y=\frac{3}{5}x-3+2[/tex]
[tex]\mathbf{\displaystyle y=\frac{3}{5}x-1}[/tex]
