Answer:
80%
Step-by-step explanation:
Today, 75 of the sixth grade students did their math homework, and 15 did not do their homework. What percentage of the sixth grade students did their homework?
The number of students that did their home work = Total number of students - Number of students that did not do their homework.
= 75 - 15
= 60 students
The percentage of the sixth grade students that did their homework is calculated as:
Number of students that did their homework/Total number of students × 100
= 60/75 × 100
= 80%

Mi-Young makes 24 cups of seafood kalguksu.This is 60% of the total kalguksu she makes.
Complete question :
Mi-Young makes 24 cups of seafood kalguksu.This is 60% of the total kalguksu she makes. Total kalguksu made is?
Answer:
40 cups
Step-by-step explanation:
Given that :
24 cups = 60% of total made
Let total kalguksu made = x
Hence,
24 cups = 0.6x
24 = 0.6x
Divide both sides by 0.6
24/0.6 = x
x = 40
Hence, total seafood Kalguksu made = 40 cups

A. Yes; the graph passes the vertical line test.
B. No; there are y-values that have more than one x-value.
C. Yes, there are no y values that have more than one x-value.
D. No; the graph fails the vertical line test.
Answer:
D. No; the graph fails the vertical line test
The correct option is D. No, the graph fails the vertical line test.
What is vertical line test?The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function. It is done by visually examining the number of intersections of the curve with vertical lines.
In the given graph, the graph of a function intersects the y axis twice.
Any vertical line in the x y plane must intersect the graph of a function at most once.
Thus, the correct option is D.

=7x-25
Answer:
(3x+4x) + (5-30)
Step-by-step explanation:
For this problem which is all addition and subtraction it is simply having you combine like terms or rather terms with same variables (3x and 4x). You just need to be careful with the signs when you rewrite the problem so when you solve you get the correct answer. Example if you were to solve this one you would combine your numbers with variable of x and then the numbers without the variable:
(3x+4x) +(5-30)
7x + -25 or 7x-25

Can someone help me out with this problem How tall is a stack of cube shaped blocks whose volumes are 375 cube inches, 648 cube inches, and 1029 cube inches?
Answer:
The stack of blocks is 25.96 inches tall
Step-by-step explanation:
The Volume of a Cube
Given a cube-shaped figure of side length L, the volume is calculated by:
[tex]V=L^3[/tex]
If the volume is known, then the side length can be found by solving for L:
[tex]L=\sqrt[3]{L}[/tex]
We are given three cube-shaped blocks with known volumes. We'll find the individual side lengths and add them up to find the height that results when they stack up vertically.
Block 1, volume 375 cube inches:
[tex]L_1=\sqrt[3]{375}=7.21\ inch[/tex]
Block 2, volume 648 cube inches:
[tex]L_2=\sqrt[3]{648}=8.65\ inch[/tex]
Block 3, volume 1029 cube inches:
[tex]L_3=\sqrt[3]{1029}=10.10\ inch[/tex]
Total height=7.21 inch+8.65 inch+10.10 inch=25.96 inch
The stack of blocks is 25.96 inches tall

If f(x) = 2x² then when x = 3, y will equal

Sara wants to find the input value that produces the same output for the functions represented by the tables.
A table headed with f(x) equals negative 0.5 x plus 2, with 2 columns and 8 rows. The first column, x, has the entries, negative 3, negative 2, negative 1, 0, 1, 2, 3. The second row, f(x), has the entries 3.5, 3, 2.5, 2, 1.5, 1, 0.5. A table headed with g(x) equals 2 x minus 3, with 2 columns and 8 rows. The first column, x, has the entries, negative 3, negative 2, negative 1, 0, 1, 2, 3. The second row, g(x), has no entries.
What is the input value that produces the same output value in both charts?
–2
–1
1
2
Answer:
2 is the value that provides the same result with f(x) and g(x).
Step-by-step explanation:
You can solve this by saying:
f(x) = g(x)
and then solving for x.
So let's do it:
[tex]f(x) = g(x)\\-0.5x + 2 = 2x - 3\\2x + 0.5x = 2 + 3\\2.5x = 5\\x = 2[/tex]
This tells us that when x = 2, the two functions will have identical values. Let's try them out to confirm it!
f(x) = -0.5x + 2
f(2) = -0.5 * 2 + 2
f(2) = -1 + 2
f(2) = 1
g(x) = 2x - 3
g(2) = 2 * 2 - 3
g(2) = 4 - 3
g(2) = 1
So we can see that 2 is the value that produces the same result in both charts.
The input value that produces the same output value in both charts is 2. so the correct answer is option D.
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
here, we have,
You are given two functions f (x) = -0.5X +2 and g(x) = 2x - 3

g(-2) = 2 -(-2) -3 = -7
g(-1) = 2( -1) -3 = -3
g(0) = 2 - 0 - 3 = -3
g(1) = 2.1 - 3 = -1
g(2) = 2.2 -3 = 1
g(3) = 2.3 -3 = 3
Hence the second table will be

Bob walked 20 miles in 4 hours. Kelly walked 14 miles in 3 hours. Are these rates proportional
Answer:
No
Step-by-step explanation:
20/4=5
14/3=4.67
Since they're not the same, they're not proportional.
Answer:
not proportional
Step-by-step explanation:
First , let's find the speed of each person by dividing the distance traveled and the time.
Using B to represent Bob's speed and K to represent Kelly's speed , we have:
[tex]B=\frac{20}{4} = 5 mph\\K=\frac{14}{3}= 4.666 mph\\\\[/tex]
The speeds 5 and 4.666 are not multiples , so they are NOT proportional.

Answer: 1) -5.8
Step-by-step explanation:
in order to solve the problem you have to put it together:
9x-5 = 14x+24
then go from there : subtract 24 on both sides , then subtract 9x on both sides , that’ll leave you with : -29 = 5x
so from there we divide , giving us x= -5.8

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
y = 4x be equation (1)
On simplifying the equation , we get
when x = 1
y = 4 ( 1 )
y = 4
when x = 2
y = 4 ( 2 )
y = 8
when x = 3
y = 4 ( 3 )
y = 12
when x = 4
y = 4 ( 4 )
y = 16
Therefore , the values of y are { 4 , 8 , 12 , 16 }
Hence , the equation is y = 4x
