Two boxes are shown below. What is the combined volume? Show your work
Check the picture below.
The solution is, the combined volume of the boxes is 180 unit cube.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
from the given diagram, we get,
there is two boxes in the diagram.
now, we have to find the combined volume.
here, we get,
the boxes are cuboids.
we know that,
Volume of cuboid = length * width * height
V = l*w*h
here, we get, from the figure,
for 1st box, l = 3, w = 5 , h = 8
so, V = 3 * 5 * 8 = 120
and, for 2nd box, l = 4, w = 5, h = 3
so, V = 4*5*3 = 60
we get, the combined volume 120 + 60 = 180
Hence, The solution is, the combined volume of the boxes is 180 unit cube.

in terms of height.
9 Modelling The inside of a saucepan has diameter 20 cm and height 13 cm.
The manufacturer claims that the pan has a capacity of 4 litres.
Is the claim correct?
Explain your answer.
Step-by-step explanation:
this is practically a cylinder.
the volume of a cylinder is
ground area × height = pi×r² × height.
r being the radius (half of the diameter).
so, we have here
V = pi×10² × 13 = pi × 100 × 13 = 1300pi =
= 4,084.07045... cm³
1 liter = the content of a cube with 10 cm side length.
10×10×10 cm³ = 1000 cm³ = 1 liter.
the pan has a volume of 4,084.07045... cm³, so, yes, it has the capacity of 4 liters as 4×1000 cm³ (and a little bit extra).

what is the following ratio using two other notations. 3:8
Answer:
3 to 83/8Step-by-step explanation:
You want to see two other ways to write the ratio 3:8.
RatiosA ratio is a way of saying that some number of one thing is always associated with some (often different) number of another thing. The two things may or may not be measured with the same units, and may or may not refer to parts of the same object.
Here, we're concerned with how we write a ratio. One way is shown in the problem statement:
3 : 8 . . . . . . . . using a colon
Two other ways to write the same ratio are ...
3 to 8 . . . . . . using the word "to"
3/8 . . . . . . . . using a fraction bar
__
Additional comment
A ratio is in "simplest form" if the numbers involved are mutually prime (have no common factors).
Sometimes an extended ratio is useful for specifying the relationship between more than two measures, for example, 3 : 8 : 5.

For each polynomial function, rewrite the polynomial in standard form. Then state its degree and constant term.
a. f(x) = (x + 1)(x+3)(x-4)
b. g(x) = 3(x + 1)(x+3)(x-4)
a. The stand form is f(x) = x^3 - 13x - 12
degree = 3
constant term = - 12
b. The stand form is g(x) = 3 x^3 - 39x - 36
degree = 3
constant term = - 36
Given data
f(x) = (x + 1)(x+3)(x-4)
g(x) = 3(x + 1)(x+3)(x-4)
How to find the standard form of the polynomialsfor f(x) = (x + 1)(x+3)(x-4) we have
f(x) = (x + 1)(x+3)(x-4)
f(x) = ( x + 1 ) ( x^2 - 4x + 3x - 12 )
f(x) = (x + 1) ( x^2 - x - 12 )
f(x) = x^3 - x^2 - 12x + x^2 - x - 12
f(x) = x^3 - 13x - 12
degree = 3
constant term = -12
g(x) = 3(x + 1)(x+3)(x-4)
g(x) = 3(x + 1) ( x^2 - 4x + 3x - 12 )
g(x) = 3(x + 1) ( x^2 - x - 12 )
g(x) = 3 ( x^3 - x^2 - 12x + x^2 - x - 12 )
g(x) = 3 ( x^3 - 13x - 12 )
g(x) = 3 x^3 - 39x - 36
degree = 3

Cynthia Besch wants to buy a rug for a room that is 18 ft wide and 32 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 176 square feet of carpeting. What dimensions should the rug have?
The rug will have dimension of 8ft. wide and 22ft. long.
Dimensions of room :
Wide (w) = 18 ft.
Long (l) = 32 ft.
Area of the room = l × w
= 32 × 18 = 576 ft²
Cynthia wants to leave a uniform strip of floor around the rug.
Let the width of the rug = x ft.
Then the dimensions of the rug will be = (18- 2x)ft. × (32- 2x)ft.
Area of the rug = (18 - 2x) × (32 - 2x) ft²
176 = (18 - 2x) × (32 - 2x)
176 = 576 - 36x - 64x + 4x²
4x² - 100x + 400 = 0 ( Divide the equation by 4 )
x² - 25x + 100 = 0
x² - 20x - 5x + 100 = 0
x(x - 20) -5(x - 20) = 0
(x - 20) (x - 5) = 0
x = 20, 5
If we take 20 as x then it will become a negative number when we will substract it from dimensions of the rug.
Therefore, The width of the rug will be 5 ft.
Thus, The Dimension of the rug = (18- 2x)ft. × (32- 2x)ft.
= (18 - 10) × (32 - 10)
= 8ft. × 22ft.

its P -intercept is
its n -intercepts are
The P-intercept of the function P(x) is 0.
The n -intercepts of the function are n = 0, -3 and -7
How to find the intercepts of a function?
We are given the function;
P(n) = 3n⁴ + 30n³ + 63n²
Now, the P intercept of the function P(n) will occur when n = 0. Thus;
P(0) = 3(0)⁴ + 30(0)³ + 63(0)²
P(0) = 0
Thus, the P intercept of the function P(x) is 0.
Now, the n-intercept will be the roots of the given function P(x). Thus;
3n⁴ + 30n³ + 63n² = 0
n²(3n² + 30n + 63) = 0
Thus;
n² = 0 or 3n² + 30n + 63 = 0

The total cost to the nearest cent is $22.00 when haircut is $20 and tip is 10%.
To find the total cost, we need to add the cost of the haircut and the tip amount.
Given:
Haircut cost = $20
Tip percentage = 10%
First, calculate the tip amount:
Tip = (10/100) × Haircut cost
Tip = (10/100) × $20
Tip = $2
Add the haircut cost and the tip amount to find the total cost:
Total cost = Haircut cost + Tip
Total cost = $20 + $2
Total cost = $22
Therefore, the total cost to the nearest cent is $22.00.

sign with your answer.
60 percent of the original price is saved if the futon bed is purchased.
The percent of the original price that will be saved can be calculated as followsThe original price of the futon bed is $500
The new price is $200
The first step is to calculate the price change
Price change= 500-200
= 300
The amount saved can be calculated as follows
300/500 × 100
= 0.6 × 100
= 60

f(t) = 10.72 × [tex](0.9* 17 + 10)^{0.3}[/tex]
f(t) = 10.72 × [tex](15.3 + 10)^{0.3}[/tex]
f(t) = 10.72 × [tex](25.3)^{0.3}[/tex]
f(t) = 10.72 × 2.6359
f(t) = 28.2573 % per year
The rate % of Americans age 55 and older changing at the beginning of 2017 rounded off to two decimal places will be :
