A company rents two storage units. Both units are cube-shaped. what is the difference in volume of the two storage units? note that the volume of a cube is s cubed where s is the side length explained
The question is missing the figure. So, the figure is attached below.
Answer:
237.375 ft³
Step-by-step explanation:
Given:
Side length of bigger cube is, [tex]S_1=8\ ft[/tex]
Side length of smaller cube is, [tex]S_2=6.5\ ft[/tex]
Now, volume of the bigger storage unit is given as:
[tex]V_1=S_1^3\\V_1=S_1\times S_1\times S_1\\V_1=8\times 8\times 8=512\ ft^3[/tex]
Volume of the smaller storage unit is given as:
[tex]V_2=S_2^3\\V_2=S_2\times S_2\times S_2\\V_2=6.5\times 6.5\times 6.5=274.625\ ft^3[/tex]
Now, difference in the volume of the two storage units is given as:
[tex]V_1-V_2=512-274.625=237.375\ ft^3[/tex]
Therefore, the difference in their volumes is 237.375 ft³.
To find the difference in volume between two cube-shaped storage units, determine the length of one side for each cube, calculate their volumes with the formula 'Volume = side length cubed', and subtract one volume from the other.
Explanation:To calculate the difference in volume between the two cube-shaped storage units, follow these steps:
Obtain the side length (s) of each cube.Calculate the volume (V) of each cube using the formula V = s^3. This equation is derived from the standard SI unit of volume which is a cubic meter (m³). This means that the volume of a cube is equal to the length of one side cubed.Subtract one volume from the other to find the difference.For example, let's assume the side length of cube 1 is 2 meters and the side length of cube 2 is 3 meters. The volume of cube 1 will be 2^3 or 8 m³ and the volume of cube 2 will be 3^3 or 27 m³. The difference in volume between the two cubes would be 27 m³ - 8 m³ = 19 m³.

A metalworker has a metal alloy that is 20% copper and another alloy that is 70% copper. How many kilograms of each alloy should the metalworker combine to create 60 kg of a 50% copper alloy? The metal worker should use (blank) kilograms of the metal alloy that is 20% copper and (blank) kilograms of the metal alloy that is 70% copper.
X+Y=60kg
X=60-Y
X*0.2+Y*0.7=60*0.5
(60-Y)*0.2+Y*0.7=30
12-0.2*Y+0.7*Y=30
0.5*Y=18
Y=36 kg
X=60-36
X=24 kg

Laura drew the triangle shown below. Side A is 7.8 cm in length. Side C is 9.5 cm in length. What is the measure of angle x, in degrees?
Answer:
55.19 degrees
Step-by-step explanation:
See the given diagram of the triangle attached to this question.
This is a right triangle and one of its angles other than 90° is x degrees.
Now, if we assume c is the hypotenuse and a is the perpendicular, then we can write that
[tex]\sin x = \frac{\textrm{Perpendicular}}{\textrm {Hypotenuse}} = \frac{a}{c}[/tex]
Now, it is given that a = 7.8 cm and c = 9.5 cm.
Therefore, [tex]\sin x = \frac{7.8}{9.5} = 0.821[/tex]
⇒ [tex]x = \sin^{-1} (0.821) = 55.19[/tex] degrees. (Answer)

An element with mass 820 grams decays by 26.8% per minute. How much of the element is remaining after 18 minutes, to the nearest 10th of a gram?
Answer:
3.0 grams of the element are left after 18 minutes
Step-by-step explanation:
Recall that an exponential decay that can be studied with the following formula for the amount of material (A) as a function of time (t):
[tex]A(t)=A_0(1-r)^t[/tex]
where:
[tex]A_0[/tex] is the starting amount of the substance (in our case 820 grams)
r is the rate of decay (which in our case given as 26.8% can be written in decimal form as 0.268
and t is the time in minutes (in our case t = 18 minutes)
Then we have:
[tex]A(t)=A_0(1-r)^t\\A(18)=820*(1-0.268)^18\\A(18)=820*(0.732)^18\\\\A(18)=2.985\,grams[/tex]
which can be rounded to 3.0 grams
Answer: 3.0
Step-by-step explanation:
a=820
r= rate= 26.8%=0.268
b=1-r=1-0.268=0.732
y=820(0.732)^18
y=2.985474

1. What are transition metals?
Answer:
Any of the set of metallic elements occupying a central block (Groups IVB–VIII, IB, and IIB, or 4–12) in the periodic table, e.g., iron, manganese, chromium, and copper. Chemically they show variable valence and a strong tendency to form coordination compounds, and many of their compounds are colored.
Step-by-step explanation:
The graph shows g(x), which is a translation of f(x) = x^2. Write the function rule for g(x). Show step by step.
Points on nonlinear graph are (9,10) (5,10) (7,6).
Using the given points, solve for a, h, k in g(x) = [tex]a(x - h)^2[/tex] + k . The function rule is g(x) = [tex]a(x - h)^2[/tex] + k .
To find the function rule for g(x), which is a translation of the quadratic function[tex]\( f(x) = x^2 \)[/tex], we need to determine the horizontal and vertical shifts based on the given points on the graph. The general form for a translated quadratic function is [tex]\( g(x) = a(x - h)^2 + k \)[/tex], where (h, k) represents the vertex of the parabola.
Let's use the given points (9,10), (5,10), and (7,6) to find the translation values.
1. Vertex Form of Quadratic Function:
The vertex form of a quadratic function is [tex]\( f(x) = a(x - h)^2 + k \)[/tex], where (h, k) is the vertex. Let's find the vertex using the given points.
For (9,10):
[tex]\[ 10 = a(9 - h)^2 + k \][/tex]
For (5,10):
[tex]\[ 10 = a(5 - h)^2 + k \][/tex]
For (7,6):
[tex]\[ 6 = a(7 - h)^2 + k \][/tex]
2. Solve the System of Equations:
Solve the system of equations to find the values of a , h , and k .
3. Substitute into Vertex Form:
Once you find the values of a , h , and k , substitute them into the vertex form g(x) = [tex]a(x - h)^2[/tex] + k.
By following these steps, you'll obtain the function rule for g(x), which is a translation of [tex]f(x) = x^2[/tex] based on the given points on the graph.

question: Jack and Julio each improved their yards by planting daylilies and geraniums. They bought their supplies from the same store.
Jack spent $22 on 1 daylily and 5 geraniums. Julio spent $30 on 13 daylilies and 1 geranium. Find the cost of one daylily.
Answer:
$2
Step-by-step explanation:
x = daylily
y = geranium
1x + 5y = 22
13x + 1y = 30
Multiply second equation by 5 and subtract the two equations.
1x + 5y = 22
- (65x + 5y = 150)
-64x = -128
x = 2
So one daylily costs 2 dollars

a. Which mix would make the most “appley” juice? Explain your
reasoning
Final answer:
To make the most 'appley' juice, use a mixture with a high percentage of pure apple juice and minimal amounts of other ingredients.
Explanation:
To make the most "appley" juice, you would want to use a mixture that has a high concentration of apple juice. In this case, the best choice would be a mixture with a high percentage of pure apple juice and minimal amounts of other ingredients. This would ensure that the flavor of the juice is predominantly apple.
For example, a mixture with 90% apple juice and 10% other fruit juices would have a strong apple flavor. On the other hand, a mixture with 50% apple juice and 50% other fruit juices would have a less pronounced apple taste.
By experimenting with different ratios of apple juice to other ingredients, you can find the mixture that results in the most "appley" juice.

How old are each of the 3 men? explain in your own words of how u get the answer
Ages of Mark, Brett and Carl are 80 years, 60 years and 70 years respectively.
Solution:
Given that
Brett is 18 years younger than Mark.
Carl is 10 years younger than Mark.
The sum of the ages of Brett, Mark, and Carl is 212
Need to determine age of Brett, Mark, and Carl.
Let assume age of mark in years be represented by variable x
As it is given that Brett is 18 years younger than Mark , so if we subtract 18 from the age of Mark we will get age of Brett ,
=> Age of Brett = x – 18
Also given that Carl is 10 years younger than Mark , so if we subtract 10 from the age of Mark we will get age of Carl ,
=> Age of Carl = x – 10
Given sum of ages of Brett, Mark, and Carl is 212
=> Age of Mark + Age of Brett + Age of Carl = 212
=> x + ( x – 18 ) + ( x – 10) = 212
=> 3x – 28 = 212
=> 3x = 212 + 28
Age of Mark = x = 80 years
Age of Brett = x – 18 = 80 – 18 = 62 years
Age of Carl = x – 10 = 80 – 10 = 70 years
Hence Ages of Mark , Brett and Carl are 80 years, 60 years and 70 years respectively.
Ed stein paid $40.00 interes tonaloan
OF $2,000 for 3 months
what's the rate of interest hepaid?
Answer:
The rate of interest paid on the principal amount is 8%.
Step-by-step explanation:
Here, Principal Amount = $2,000
Time = 3 months = (3/ 12 ) Years = 0.25 years
Rate = R
Interest Amount = $40
Now, as we know :
Simple Interest = [tex]\frac{P \times R \times T}{100}[/tex]
⇒[tex]40 = \frac{2,000 \times R \times 0.25}{100}\\\implies R = \frac{40 \times 100}{2000 \times 0.25} =8[/tex]
or, R = 8%
Hence, the rate of interest paid is 8%.
