Answer:
W = 4
Step-by-step explanation:
The nice thing about algebra is that you can look for any variable in an equation as long as you have the number for the other variables.
1. Write our the equation. V = l w h
2. Put in as many numbers as you can. 60 = 5 w 3
3. Isolate the variable. To do that perform the mathematical opposite to the target on both sides. So to get rid of five, we have to divide it on both sides of the equal sign.
60/5 = w 3
12/3 = w
4 = w
The width is 4cm

Answer:
y = x⁴- 5x² + 4
y = x(x + 3)(x - 2)
Step-by-step explanation:
1). y = x⁴- 5x² + 4
= x⁴- 4x² - x² + 4
= x²(x² - 4) - 1(x²- 4)
y = (x² - 1)(x² - 4)
y = (x - 1)(x + 1)(x - 2)(x + 2)
Therefore, zeros of this polynomial are,
x = -2, -1, 1, 2
From the given graphs, first graph has the zeros (x-intercepts) as x = -2, -1, 1, 2.
So the graph (1) represents the polynomial → y = x⁴- 5x² + 4
2). Second graph shows the x-intercepts at x = -3, 0, 2
Since, y = x(x + 3)(x - 2) is the polynomial with x intercepts at x = -3, 0, 2
Therefore, y = x(x + 3)(x - 2) represents the second graph.

(-12,14) and (6,-1) write the linear equation in slope-intercept form that passes through the given points. PLEASE HELP ASAP THANK YOU!!!
The equation of the line written in slope intercept form is 0.8333x + 24
From the question given :
x1 = - 12 ; y1 = 14 ; x2 = 6 ; y2 = - 1General form of a slope intercept equation :
y = bx + cb = slope = (y2 - y1) / (x2 - x1)
Slope = (-1 - 14) / (6 - (-12)) = - 15 / 18 = 0.8333
The intercept, c can be obtained thus :
14 = 0.8333(-12) + c
14 = - 10 + c
14 + 10 = c
c = 24
Therefore, the equation can expressed thus y = 0.8333x + 24

Ryan and his children went into a bakery and will buy cupcakes and brownies. Each cupcake costs $4.75 and each brownie costs $1. Ryan has a total of $50 to spend on cupcakes and brownies. Write an inequality that would represent the possible values for the number of cupcakes purchased, cc, and the number of brownies purchased, b.b.
Answer: 4.75c+1b ≤50
Step-by-step explanation: One cupcake costs $4.75, so “c” cupcakes cost $4.75. One brownie cost $1, so “b” brownies cost 1b. The total 4.75c+1b must be less or equal to $50.

Given the equation 5x + 3y = 15, which statement is true?
-The x-intercept is 5, and the y-intercept is 3.
-The x-intercept is 3, and the y-intercept is 5.
-The x-intercept is –, and the y-intercept is 15.
-There is not enough information to determine the intercepts.
Answer:
Step-by-step explanation:
5x+3y=15
divide by 15
[tex]\frac{x}{3} +\frac{y}{5} =1[/tex]
which is of the form
[tex]\frac{x}{a} +\frac{y}{b} =1[/tex]
where a and b are x & y intercepts.
x-intercept=3
y-inntercept=5
78 % of the class scored a C or above on their test. If there are 35 students in the class, how many scored a C or higher? Write and solve a proportion for this situation.
Answer:
27 students
Step-by-step explanation:
[tex]\frac{78}{100} =\frac{x}{35} \\[/tex]
cross multiply and you get 27
All this question is trying to ask is to find 78% percent of the total number of student in the class.
So first convert 78 to decimal by dividing it by 100: [tex]\frac{78}{100} = 0.78[/tex]
Next multiply that with the total number of students which is 35.
So, [tex]0.78 * 35 = 27.3[/tex]
Now I don't think there can be a decimal here. The question must be wrong or the percentage might be incorrect. But, just for sake, we'll round it up so the final answer would be: [tex]27[/tex]
The proportion would be: [tex]273:10[/tex]

Use the formula to find the midpoint between a segment with endpoints
(0,5) and (-4, 6). *
Answer:
Step-by-step explanation:
(x₁ ,y₁) = (0 , 5) & (x₂, y₂) = (-4 , 6)
[tex]Midpoint = (\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})\\\\[/tex]
[tex]= (\frac{0 - 4}{2} , \frac{5+6}{2}) \\\\= (\frac{-4}{2} , \frac{11}{2})\\\\=(-2 , 5.5)[/tex]
The mid-point is the average of the respective values for x and y.
So, the formula for the mid-point would be: [tex](\frac{x_{2} + x_{1}}{2}, \frac{y_{2} + y_{1}}{2})[/tex]
So for your problem this would be:[tex](\frac{-4}{2}, \frac{11}{2})[/tex]
So the final answer would be: [tex](-2, 5.5)[/tex]

Carlos is packing bags for treats at a party. Every bag has exactly the same amount of treats in it. Carlos has 25 granola bars and 35 small popcorn balls. What is the greatest number of treat bags Carlos can make?
Answer:
5 bags
Step-by-step explanation:
Given
[tex]Granola\ Bars = 25[/tex]
[tex]Popcorn\ Balls = 35[/tex]
Required
Determine the greatest number of bags
This question illustrates greatest common factor (GCF).
The number of bags will be solved by getting the GCF of 25 and 35.
This is shown below:
[tex]25 = 1 * 5 * 5[/tex]
[tex]35 = 1 * 5 * 7[/tex]
[tex]GCF = 1 * 5[/tex]
[tex]GCF = 5[/tex]
Hence, Carlos will need 5 bags

9.
Explanation: So for question 9, you need to find the LCD (Least common denominator) so you list out the multiples of 8 and 4, when doing so, you find out that 8 is the LCD of both, since 8 is both a multiple of itself and of 4.
So, to get the answer, you do 4 * 2 and anything you do to the denominator (bottom number), you do to the nominator (top number).
So now you have -8/3/8 +6/2/8 then you just add the nominators and whole numbers like normal. You get, -2/1/8 (Remember you are adding a positive number to a negative number.)
Answer: -2/1/8
10.
Explanation: Same process as question 9.
Answer: -4/1/12

Explanation: Read -7.3 out loud, it would be negative seven and 3 tenths, that makes it easy to convert as a fraction. It would be -7/3/10. Do the same for the other number, and you have -3/6/10, then you just add. You get -10/9/10.
Answer: -10/9/10
12.
Explanation: Same process as question 11. (You're in the thousandths now.) You get 3/535/1000. Reduce.
Answer: 3/107/200
13.
Explanation: You have 2 options here, to convert the decimal into a fraction, or to convert the fraction into a decimal, I'll be changing the fraction into a decimal, you wanna write it as a 10 as a denominator, so to get to 10 you multiply the denominator by 2, and anything you do to the denominator, you do to the nominator. So, -3/2/5 as a decimal is: -3.4, then you go ahead and compare them and you can see that the temperature in town A is colder.
Answer: The temperature in town A is colder.

the squirrel ran faster than 11.3 feet per second
the squirrel ran no faster than 102 feet per second
the squirrel ran slower than 102 feet per second
_______________________________________________________
Answer:
✔ 3r > 34
✔ r > 11.3
✔ The squirrel ran faster than 11.3 feet per second.
Step-by-step explanation:
1. The Squirrel's speed is 3r > 34
2. The solution of the inequality is r > 11.3
3. The interpretation is: The squirrel ran faster than 11.3 feet per second.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
A squirrel runs across a road in 3 seconds.
The road was more than 34 feet wide.
1. The Squirrel's speed is
3r > 34
2. The solution of the inequality is
r > 34/3
r > 11.3
3. The interpretation is: The squirrel ran faster than 11.3 feet per second.
