Solve equation 5(n-4) = -60
Answer:
n = -8
Step-by-step explanation:
The variable has 4 subtracted and that quantity is multiplied by 5. You can find the value of the variable by reversing these operations, in reverse order. That means you first divide both sides of the equation by 5:
5(n-4)/5 = -60/5
n -4 = -12 . . . . . . simplify
Then you undo the subtraction of 4. You accomplish that by adding 4 to both sides of the equation.
n -4 +4 = -12 +4
n = -8 . . . . . . . . . simplify
_____
This equation can also be solved by first eliminating parentheses. Then you have
5n -20 = -60
Now, the variable is multiplied by 5, then 20 is subtracted from the sum. Reversing these operations in reverse order, we first add 20 to both sides of the equation:
5n -20 +20 = -60 +20
5n = -40 . . . . . . . . . . . . . simplify
Then we undo the multiplication by dividing both sides of the equation by 5:
n = -8
_____
The rule to remember is "whatever you do to one side of the equation must also be done to the other side". This is what keeps the equal sign valid.
Answer:
n = - 8
Step-by-step explanation:
There are 2 possible approaches to solving this question
method 1
5(n - 4) = - 60 ( divide both sides by 5 )
n - 4 = - 12 ( add 4 to both sides )
n = - 8
method 2
5(n - 4) = - 60 ( distribute left side )
5n - 20 = - 60 ( add 20 to both sides )
5n = - 40 ( divide both sides by 5 )
n = - 8

Which description best fits the distribution of the data
shown in the histogram?
A. The mean is greater than the median.
B. The mean and median are approximately the same
C. The mean is less than the median
Answer:
The correct option is A.
Step-by-step explanation:
From the given histogram it is clear that it is right skewed or positive skewed distribution because the tail is stretched toward right.
Negative skewed: Mean < Median < Mode
No skewed: Mean = Median = Mode
Positive skewed: Mean > Median > Mode
Since the given histogram is positive skewed distribution, therefore mean is greater than the median.
Hence the correct option is A.

For table 3:
Calculating value of m using eq 1 for points (1,7) and (2,11)
[tex]m=\dfrac{11-7}{2-1}\\\\m=4[/tex]
Calculating value of m using eq 1 for points (3,12) and (4,13)
m=1
Value of slope changes from 4 to 1. Thus, it does not show linear relationship.
For table 4:
Calculating value of m using eq 1 for points (2,7) and (4,9)
[tex]m=\dfrac{9-7}{4-2}\\\\m=1[/tex]
Calculating value of m using eq 1 for points (6,12) and (8,15)
m=3/2
Value of slope changes from 1 to 3/2. Thus, it does not show linear relationship.
So, the Slope of table 1 is the same for all the coordinates. Thus, table 1 represents a linear function.

what is the coordinates of the vertex of y+10=4(x-1)^2
Answer:
(1, -10)
Step-by-step explanation:
Only the y can be on the left hand side. The square has been completed so all you need do is transfer the 10 to the right and read the x,y values for the vertex.
I have provided a graph to show you that the vertex and my answer are the same (hopefully).
y + 10 = 4(x - 1)^2 Subtract 10 from both sides.
y + 10-10=4(x -1)^2 -10 Combine
y = 4(x - 1)^2 - 10
Now we need to make the square term = 0
x - 1 = 0 Add 1 to both sides
x - 1 + 1 = 0 +1 Combine
x = 1 When x = 1 the square term will equal 0.
The vertex should be (1, - 10)

Which phrase is represented by the expression 5x ( 36+ 9)?
Final answer:
The expression 5x (36+9) simplifies to 225 by first adding the numbers in the parentheses (36+9) to get 45, and then multiplying 5 by 45.
Explanation:
The expression 5x (36+9) represents the phrase 'five times the sum of thirty-six and nine.' To evaluate this expression, you first perform the operation inside the parentheses. In this case, you add 36 and 9, which equals 45. After simplifying the parentheses, the expression becomes 5x45. As the final step, you multiply 5 by 45, which equals 225. Therefore, the expression 5x (36+9) equals 225.

The percentage of the sales tax Chan pay if Chan bought a $345 smartphone, but his total was $365.70 is 6%.
What is percentage?A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.
Given:
The cost of smartphone = $345
The total amount = $365.7
Calculate the percentage as shown below,
Percentage of tax = The total amount - The cost of smartphone / The cost of smartphone × 100
Percentage of tax = (365.7 - 345) / 345 × 100
Percentage of tax = 20.7 / 345 × 100
Percentage of tax = 0.06 × 100

what is angle COD????
Given a straight line segment AB with points A, O, and B, and angle measures <COA, <COD, and <DOB, we find <COD to be 45 degrees using angle sum properties.
In the given scenario, we have a straight line segment AB, and points O, A, and B lying on it. We are required to find the measure of angle COD, denoted as <COD. According to the information provided, <COA is (3x + 94), <COD is (x + 36), and <DOB is (2x - 4).
Since A, O, and B are collinear, the sum of the angles around point O must be 180 degrees. Therefore, <COA + <COD + <DOB = 180 degrees. Substituting the given angle measures into the equation, we get:
(3x + 94) + (x + 36) + (2x - 4) = 180.
Combining like terms and solving for x:
6x + 126 = 180,
6x = 54,
x = 9.
Now that we have the value for x, we can find <COD by substituting it into the expression (x + 36):
<COD = 9 + 36 = 45 degrees.
Therefore, the measure of angle COD is 45 degrees.
Twelve students earned A's. This was 3/8 of the students in the class. What percent of the students did not earn A's?
Answer:
62.5% of the class
Step-by-step explanation:
If 12 students is 3/8 of the class, the ones who earned A's, then 5/8 did not earn A's.
Let c represent the total number of students in the class.
Then (3/8)c = 12, and c = (8/3)(12) = 32.
5/8 of these 32 students did not earn A's: (5/8)(32) = 20.
These 20 students constitute 20/32 of the class, or 0.625 of the class, or 62.5% of the class.

This means that when they used 4 lemons then they sold around 32 cups
(5, 40)
This means that when they used 5 lemons then they sold around 40 cups
(6, 35)
This means that when they used 6 lemons then they sold around 40 cups
(7, 26)
This means that when they used 7 lemons then they sold around 26 cups
It can be seen that the last case is when they sold the least number of cups.
What is the surface area of this cylinder? Please show steps!
Answer:
251.33
Step-by-step explanation:
the formula is π r-squared h
so the formula for this question is π (2 squared)(20)
you will square 2 to get 4 then multiply that by π then lastly multiply by 20
Answer:
area = (exact) 88pi ft^2 or (approximate) 276 ft^2
Step-by-step explanation:
The surface area of a cylinder is the sum of the areas of the bases, two circles, and the lateral area which is a rectangle.
Each base is a circle, and the two bases are congruent, so find the area of one base and multiply by 2.
The lateral area is a rectangle. You need to find the length and width of the rectangle. Think of a can of food with a label wrapped around. If you make a vertical cut from one base to the other, and you unwrap the label, you will see that the lateral surface of a cylinder is a rectangle that has the height of the cylinder as its length, and the circumference of the base are its width.
area of circle = pi *r^2
area of rectangle = length * width
length of rectangle: length = 2(pi)r
width of rectangle: width = height = h
total area of cylinder = area of bases + lateral area
total area of cylinder = 2 * pi *r^2 + 2(pi)r * h
total area of cylinder = 2 * pi * (2 ft)^2 + 2 * pi * 2 ft * 20 ft
total area of cylinder = 8pi ft^2 + 80pi ft^2
total area of cylinder = 88pi ft^2
The exact area is 88pi ft^2.
If you need an approximate area, then use 3.14 for pi.
area = 88 * 3.14 ft^2
area = 276 ft^2

Step-by-step explanation:
Answer:
Y = x÷2
Step-by-step explanation:
For this purpose, we have to examine all the x and y values.
Looking at the first x value which is 24, the output is 12 which is half of the input.
Then for second input x=12, the output is y=6, which again is half of the output.
Then for the last value of x, the same rule applies.
So we can conclude that y=x/2 or y=x÷2.

Evaluate the expression.
8^7/8^7
The value of the expression (8^7)/(8^7) is 1.
The expression (8^7)/(8^7) can be simplified using the properties of exponents. According to the quotient rule of exponents, when dividing two numbers with the same base, the exponents are subtracted. In this case:
(8^7)/(8^7) = 8^(7-7) = 8^0
Any non-zero number raised to the power of 0 is equal to 1, according to the fundamental property of exponentiation. Therefore, the value of the expression (8^7)/(8^7) is 1.
Hence, the value of the expression (8^7)/(8^7) is 1.
By applying the quotient rule of exponents, we simplify the expression to 1, reflecting the property of exponentiation where any non-zero number raised to the power of 0 equals 1.
If a cone and sphere have the same radius and the same height, what is the relationship among the volumes of the two shapes?
Answer:
the volume of the sphere will be 4 times the volume of the cone;
Step-by-step explanation:
The question is on volume comparison
Volume of a sphere=4/3 [tex]\pi[/tex]×r³
Volume of a cone= [tex]\pi[/tex]/3×r²h
where r is the radius and h is the height
Apply the condition
If r=h=1 unit
Then volume of sphere will be= 4/3 × [tex]\pi[/tex]×1³ = 4/3[tex]\pi[/tex]
And volume of the cone will be= [tex]\pi[/tex]/3 ×1²×1 =[tex]\pi[/tex]/3
We can see the volume of the sphere will be 4 times the volume of the cone;
4/3[tex]\pi[/tex] = 4×[tex]\pi[/tex]/3
The volume of the sphere is exactly twice the volume of the cone.
To establish the relationship between the volumes of a cone and a sphere when they have the same radius and height, we need to use the formulas for the volumes of these shapes.
Let's denote the radius of both the cone and the sphere as r and the height of the cone (which is also the diameter of the sphere) as h .
The volume V of a sphere is given by the formula:
[tex]\[ V_{\text{sphere}} = \frac{4}{3}\pi r^3 \][/tex]
The volume V of a cone is given by the formula:
[tex]\[ V_{\text{cone}} = \frac{1}{3}\pi r^2 h \][/tex]
Since the height of the cone is the same as the diameter of the sphere, we have [tex]\( h = 2r \).[/tex]Substituting this into the volume formula for the cone gives us:
[tex]\[ V_{\text{cone}} = \frac{1}{3}\pi r^2 (2r) = \frac{2}{3}\pi r^3 \][/tex]
Now, we can compare the volumes of the two shapes:
[tex]\[ V_{\text{sphere}} = \frac{4}{3}\pi r^3 \] \[ V_{\text{cone}} = \frac{2}{3}\pi r^3 \][/tex]
Dividing the volume of the sphere by the volume of the cone, we get:
[tex]\[ \frac{V_{\text{sphere}}}{V_{\text{cone}}} = \frac{\frac{4}{3}\pi r^3}{\frac{2}{3}\pi r^3} = \frac{4}{2} = 2 \][/tex]
Therefore, the volume of the sphere is exactly twice the volume of the cone when they have the same radius and height.
