WHICH ONE IS CORRECT?
Two cubes have edge lengths of 9 cm and 3 cm, respectively. What is the difference in volume of the two cubes?
1. 243 cm3
2. 756 cm3
3. 27 cm3
4. 702 cm3
The difference in volume of the two cubes is 702 cm3
Step-by-step explanation :
Given-
Length of edge of one cube = 9 cmLength of edge of second cube = 3 cmNow, The formula for finding volume of any cube is -
[tex] \underline{ \boxed{ \mathfrak \red{volume \: of \: cube = {edge}^{3} }}}[/tex]Therefore, substituting values. . .
Volume of one cube = [tex] {(9)}^{3} [/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: = 9 \times 9 \times 9[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 729 \: {cm}^{3} [/tex]
Similarly,
Volume of second cube [tex] = {(3)}^{3} [/tex]
[tex] \: \: \: \: \: \: \:\: \: \: \:\: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \:\: \: \: \: \: \: = 3 \times 3 \times 3[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \:\: \: = 27 \: {cm}^{3} [/tex]
Now,
Difference in volume of two cubes = Volume of 1st cube - Volume of 2nd cube
[tex] \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \:= (729 - 27) {cm}^{3} [/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 702 \: {cm}^{3} [/tex]
Thus, the difference in volume of the two cubes comes out 702 cm3
12+ b/6 = 16 what is the variable?
Answer:
[tex]b = 24[/tex]
Step-by-step explanation:
Step 1: Subtract 12 from both sides
[tex]\frac{b}{6} + 12 - 12 = 16 - 12[/tex]
[tex]\frac{b}{6} = 4[/tex]
Step 2: Multiply both sides by 6
[tex]\frac{b}{6} * 6 = 4 * 6[/tex]
[tex]b = 24[/tex]
Answer: [tex]b = 24[/tex]

MARKING BRAINLIEST What is the domain of y=0
Answer:
The answer is all real numbers :)
Step-by-step explanation:
he domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. y=0 is a straight line perpendicular to the y-axis at point (0,0) , which means that the range is a set of one value. :)

The gross margin cost for the case when the considered retailer’s gross margin on a $150 item is $40 is 26.67% approximately.
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex]
(in percentage)
Given that:
The cost of the considered item = $150The gross margin of retailer on that item = $40Here we assume that the term GMC is referring to gross margin cost.
Let this gross margin cost (GMC) $40 be P% of the original cost of the item $150.
Then, we get:
[tex]p = \dfrac{40}{150} \times 100 \approx 26.67 \text{(in percentage)}[/tex]
Thus, the gross margin cost for the case when the considered retailer’s gross margin on a $150 item is $40 is 26.67% approximately.

sorry if i am incorrect.
∠A and \angle B∠B are supplementary angles. If m\angle A=(6x+10)^{\circ}∠A=(6x+10)
∘
and m\angle B=(4x+30)^{\circ}∠B=(4x+30)
∘
, then find the measure of \angle B∠B.
If u give answer ill give 100 points NOT FAKE PLS I NEED HELP
Answer:
86 Degrees
Step-by-step explanation:
First we need to apply the defenition of a Supplementary Angle: A supplrementary angle means an angle whos measure is 180degrees.
As we are given two angles labled supplementary we must know that angleA + angleB = 180degrees.
Now we are given two equations for the measure of each angle.
measure of A = 6x+10
measure of B = 4x+30
We simply plug this into the first equation I've stated above.
6x+10 + 4x+30 = 180
Simplify
10x+40 = 180
10x = 140
x = 14
Now that we have X, we plug this into the measure B equation to get the measure.
4x + 30
(Plug 14)
4(14) + 30
56 + 30
86 Degrees

Elimination
Explanations are given below
Step-by-step explanation:
Hello!
1) SubstitutionThis is because you already have a solution for a variable, y, and you can simply plug in the value of y for the second equation
2) SubstitutionThe same thing as above, you already have the value of y, and you can simply plug it into the second equation.
3) EliminationYou should use elimination because you can simply eliminate the variable y by adding the two equations, as they have the same coefficient of 3.
4) EliminationSame as above, simply add the two equations to eliminate x, because they have the same coefficients of 7.
5) SubstitutionYou have the value for y, so simply plug it into the other equation to solve for x.
6) EliminationYou have -2x in both equations, and subtracting the equations will eliminate the variable x, and you can then solve for y.

O All real numbers except 5.
O All real numbers except 15.
O All real numbers except - 15.
O All real numbers except - 5.
Answer: D
Step-by-step explanation:
The domain of a function is the allowed 'x' values that the function can take on and produce a defined 'y' value. We can ignore the numerator since it will never be undefined. The denominator on the other hand has a singularity when it equals zero. The reason for this is because we cannot divide by zero. Therefore, lets set the denominator to zero and find which 'x' value makes the function undefined:
[tex]3x+15=0[/tex]
[tex]3x=-15[/tex]
[tex]x=-5[/tex]
Every single real 'x' value will work besides when x = -5. Therefore the answer is D

Tory and Emilio's motorboats travel at the same speed. Tory pilots her boat 30 km before docking. Emilio continues for another 2 hr, traveling a total of 80 km before docking. How long did it take Tory to navigate the 30 km?
Answer:
1.2 hours
Step-by-step explanation:
first im going to assume both travel at a constant speed the entire time
both motorboats travel 30 km, so emilio travels another 50 (80-30 = 50) km in 2 hours. speed = distance/time so the speed of the motorboats is 50/2 or 25km/h
divide 30 by 25 to get 1.2hours

Answer:
Pic 1: C.
Pic 2: D.
Step-by-step explanation:
1) The sample is the number of things picked out from a population. The amount of people surveyed is the sample, so it the answer choice showing "42 residents" as the sample is among a correct option. Since C is the only one with "42" as the sample, it is the answer.
2) Boosting morale isn't a negative thing, and will ultimately make residents happier. It leans towards "yes."
Adding a machine for enjoyment also leans towards "yes", because people will then have something fun to dsitract themselves with.
Many people will have access to the machine in the lunch room. They can also have a soft drink for lunch, which adds a tasty part to their lunch. It too leans towards "yes."
In a crowded lunchroom, the soft drink machine may be crowded by many people and it could take a while to get one for yourself. It is also vulnerable to breaking from too many people using it at once. It leans towards a "No" response.
Therefore, D is the best answer.
hope this helps!
