A box of cereal has a width of 4 inches, and a length of 8 inches and a height of 12 inches. What is the volume of the box, in cubic inches?
A box has a width of 4 inches, a length of 8 inches, and a height of 12 inches.
Use the formula V = l w h, where V represents the volume, l represents the length, w represents the width, and h represents the height.
Answer:
Volume=384 inches squared
Step-by-step explanation:
Multiply the width to the length. Therefore it would be 32. Next you multiply 32 to your height, giving you an answer of 384
Simple. 12in cubed.
Also if u wanted me to be VERY specific as to what 12in cubed equals it would be 1728.
what type of transformation is described by (x,y)-(x+2,y+3)
Answer:
reflection across the x axis.
Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

Drake is saving money to buy a new computer for $1,200. He already has $450 and plans $30 a week. The function y = 30x + 450 represents the amount Drake has saved after x weeks. How many weeks will it take Drake to save enough money to buy the computer?
Answer:
25 weeks
Step-by-step explanation:
step 1. find y which is what you are trying to find which is how long it will take for drake to make $1200
step 2.- subtract 450 from each side
1200=30x+450
-450 -450
750=30x
step 3.- divide by 30 on both sides
750=30x
30 30
x=25
i dont know if this helps but i am still learning how to explain on here. :)
Answer:
it will take him 25 weeks
Step-by-step explanation:
because 1,200 - 450= 750, and 750 divided by 30 is 25, therefore it will take him 25 weeks.

There are 37 students participating in an after-school program offering classes in yoga, bridge, and painting. Each student must take at least one of these three classes, but may take two or all three. There are 12 students taking yoga, 18 taking bridge, and 19 taking painting. There are 9 students taking at least two classes. How many students are taking all three classes
Answer: 3 students
Step-by-step explanation:
You can solve this using the expression;
Total = A + B + C - Both - all - neither
Where A, B and C represent those taking one class
As each student must take at least 1 class, there is no 'neither'.
37 = 12 + 18 + 19 - 9 - All
37 = 40 - All
All = 40 - 37
All = 3
Answer:
3
Step-by-step explanation:
I added the number of students enrolled in each class. It equaled 49.
I subtracted the number of students from that amount
49-37= 12
I subtracted the number of students enrolled in two or more classes
12-9= 3
3 are enrolled in 3 classes

Step-by-step explanation:
According to the Question , a function is given to us which is ,
[tex]\implies g(r) = 25 - 3r [/tex]
And we need to find the value of g(4) . So , substituting r = 4 , we have ;
[tex]\implies g(r) = 25 - 3r \\\\\implies g(4) = 25 - 3(4) \\\\ \implies g(4) = 25 - 12 \\\\\boxed{\red{\tt\implies g(4) = 13 }}[/tex]
Hence the required answer is 13.
write - 1/2x+ y = 10 in slope-intercept form,
Answer:
y = 1/2x + 10
Step-by-step explanation:
y = mx + b (slope intercept form equation)
-1/2x + y = 10
+1/2x +1/2x (What you do to one side must be due to the other)
y = 10 + 1/2x or y = 1/2x + 10 (use to commutative property to swap the terms)
y = 1/2x + 10 (therefore this is in slope intercept form)

Step-by-step explanation:
The nth term is given by :
[tex]d(n)=\dfrac{5}{16}\times 2^{n-1}[/tex] ...(1)
We need to find the 5th term of the above sequence. For this, put n = 5 in the above formula.
[tex]d(5)=\dfrac{5}{16}\times 2^{5-1}\\\\=\dfrac{5}{16}\times 2^4\\\\=\dfrac{5}{16}\times 16\\\\=5[/tex]
So, the 5th term in the above sequence is 5.

Ruth is at the park standing next to a slide.
Ruth is 5 feet tall, and her shadow is 3 feet
long. If the shadow of the slide is 7.5 feet
long, what is the height of the slide? Assume
the triangles are similar.
Answer:
The slide is approximately 12.75 feet.
Step-by-step explanation:
We know that Ruth is 5 feet tall, and her shadow is 3 feet tall.
5 ÷ 3 = 1.7 when rounded to the nearest tenth
Therefore, the shadow height of an object multiplied by 1.7 is the height of the actual object.
If the shadow of the slide is 7.5 feet, we need to multiply 7.5 by 1.7.
7.5 x 1.7 = 12.75
Therefore, the slide is approximately 12.75 feet.

Write a polynomial for the given real-world situation. If the length of a rectangle is 3x^2-4x+5 and the width is 2x + 1, write and simplify a polynomial expression for the area of the rectangle. 3 points for mathematical process and 2 points for correct answer.
Answer:
[tex]Area = 6x^3+-5x^{2} +6x+5[/tex]
Step-by-step explanation:
Given that:
Length of a rectangle = [tex]3x^2-4x+5[/tex]
Width of rectangle = [tex]2x + 1[/tex]
To find:
Simple polynomial expression for finding the area of rectangle.
Solution:
First of all, we should know about the formula for finding the area of rectangle. Then we should know how to multiply two polynomials.
Formula for area of a rectangle in terms of its length and width is:
[tex]Area= Length \times Width[/tex]
Putting the given values:
[tex]Area = (3x^2-4x+5)(2x+1)[/tex]
Here, we can use the distributive property of multiplication for finding the value of the above multiplication expression.
[tex](A+B)\times (C+D) = A\times C + A\times D+ B\times C + B \times D[/tex]
Therefore, the multiplication of above polynomials can be written as:
[tex]Area = (3x^2-4x+5)(2x+1)\\\Rightarrow Area = 3x^2(2x+1)-4x(2x+1)+5(2x+1)\\\Rightarrow Area = 6x^3+3x^{2} -8x^{2} -4x+10x+5\\\Rightarrow Area = 6x^3+-5x^{2} +6x+5[/tex]
Therefore, the answer is:
[tex]Area = 6x^3+-5x^{2} +6x+5[/tex]

−2(x+14)+1=5
Answer:
x=-16
Step-by-step explanation:
−2(x+14)+1=5
Step 1: Simplify both sides of the equation.
−2(x+14)+1=5
(−2)(x)+(−2)(14)+1=5(Distribute)
−2x+−28+1=5
(−2x)+(−28+1)=5(Combine Like Terms)
−2x+−27=5
−2x−27=5
Step 2: Add 27 to both sides.
−2x−27+27=5+27
−2x=32
Step 3: Divide both sides by -2.
−2x

1) Graph the quadratic function given in standard form and identify the key features. Include at least 5 points on your
graph.
y = -x2 - 2x + 1
Axis of Symmetry:
Vertex:
Y-intercept:
Domain:
Range:
Answer:
Please find attached the graph of the quadratic function is created using Microsoft Excel
1) The line of symmetry is x = -1
2) The vertex is (-1, 2)
3) The y-intercept is (0, 1)
4) The domain is -∞ ≤ x ≤ ∞
5) The range is 2 ≥ y ≥ -∞
Step-by-step explanation:
The given equation is y = -x² - 2·x + 1
The general vertex form is y = a·(x - h)² + k
h = -b/(2·a) = 2/(-2) = -1
k = f(h) = -(-1)² - 2×(-1) + 1 = 2
Therefore;
1) The line of symmetry goes through the vertex and the line of symmetry is x = -1
2) The vertex = (h, k) = (-1, 2)
3) The y-intercept is the coordinate of the point where x = 0 which is (0, 1)
4) The domain are the possible x-values, therefore, the domain = -∞ ≤ x ≤ ∞
5) The range is the possible values y-values.
From the graph, we have the range = 2 ≥ y ≥ -∞
The graph of the quadratic function is created using Microsoft Excel by generating y-values based on the equation and using the graphing function to insert a two dimensional graph of the generated combination of x and y values as shown in the attached figure.

Answer:
3.4 < x < 7.2
Step-by-step explanation:
The length of the third side of a triangle is always between the sum and difference of the lengths of the other two sides.
Here, the difference is 5.3 -1.9 = 3.4; the sum is 5.3 +1.9 = 7.2. So the length of the third side must satisfy ...
3.4 < x < 7.2
_____
Additional comment
The difference in side lengths is what you get when the shorter side is folded over the longer one. The excess of the longer over the shorter is the difference. If the triangle is to have non-zero area, the third side must be longer than that.
The sum of side lengths is what you bet when the two given sides are laid end-to-end. If the triangle is to have non-zero area, the third side must be shorter than that.
These statements are variations on the "triangle inequality", which states that the sum of any two sides must exceed the third. (That will always be the case if the sum of the shortest two sides exceeds the longest.)
an article bought for rupees 350 is sold at a profit of 20% find its selling price
Answer:
420
Step-by-step explanation:
20 percent of 350 is 70, so adding that on will give us the price it is sold at for profit of 70 (20%).
Answer:
350 is our cost price and if we add our proft we get selling price
our profit=( 20/100)×350
i.e.70 so our profit is 70
then,
350+70= selling price
we get 420 as selling price
