The volume of air inside the cube is 1887.376 cubic inches
What is Volume?The volume of a shape or an object is the amount of space in the object
How to determine the volume of air inside the cube?The given parameters are:
Volume of the ball = 113 cubic inchesThe side length of the cube = 12.6 inchesThe volume of the cube is calculated using
Volume = (Side length)^3
Substitute 12.6 for Side length
Volume = 12.6^3
Expand the exponent
Volume = 12.6 * 12.6 * 12.6
Evaluate the product
Volume = 2000.376
The volume of air inside the cube is calculated using
Volume of the air = Volume of the cube - Volume of the ball
So, we have
Air = 2000.376 - 113
Evaluate
Air = 1887.376
Hence, the volume of air inside the cube is 1887.376 cubic inches

I think before we get to this answer we need to understand how roots of a quadratic equation works.
When a quadratic equation have 2 real roots such as a/b and c/d we can write the quadratic equation in factored form like this y or 0=(bx-a)(dx-c)
In this case we know the 2 roots are 5 and 2/3 and one of the factors is already x-5. so the other one according to the equation above that I wrote have to be 3x-2 and therefore the 3rd choice is correct.
Hope this helped you and if there is any questions about this please let me know in the comments.

Answer:
8. the length is 88/5cm or 17.6cm
Step-by-step explanation:
8.perimeter =2L + 2W
when you convert the width 42/5 = 8.4
so 52 = 2L + 2*8.4
52= 2L + 16.8
52 - 16.8 = 2L
35.2 = 2L
divide both sides by 2
L = 17.6cm

PLEASE HELP ME GUYS!! ITS URGENT
Algebra 1 Please help! thank u sm
Answer:
1. Slyvia is wrong. You treat the numbers normally when dividing the left side, so 3.61/4.1 = .88. When dividing the exponents, you subtract the numerator from the denominator, so -11-7 = -18. So, you do have .88 * 10^-18, at first, but when you are working in scientific notation you want the decimal to be greater than so, which requires us to add an additional -1, to make it 8.8 instead of 0.88. This is because we want to move the decimal place left one more time. This results in our final answer being 8.8 * 10^-19, which is not Slyvia's answer.
2. Dylan's answer is correct. He subtracted the exponents correctly, then moved the decimal place over one place towards the left.
3. Ethan is wrong. He added the exponents, instead of subtracting. However, you cannot do this, because when you are dividing exponents, you must subtract.
Step-by-step explanation:
I have this acronym I learned called MADSPM, which has helped me a lot. I never learned it in Algebra, but I wish that they had taught it. Each letter corresponds with an exponent rule. If this makes sense, here is what it stands for:
When you multiply, you add.
When you divide, you subtract.
When there are parentheses, you multiply.
In this case, it was solely division. So, you just need to remember division = subtraction, when it comes to exponents.
Hopefully this helped. If you need me to explain it better, please let me know, and I will try. Thanks much & have a wonderful day!

Find the value of r so that the line through (8,r) and (4,5) has a slope of -4
Answer:
r = - 11
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 4
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, 5) and (x₂, y₂ ) = (8, r)
m = [tex]\frac{r-5}{8-4}[/tex] = [tex]\frac{r-5}{4}[/tex] = - 4 ( multiply both sides by 4 )
r - 5 = - 16 ( add 5 to both sides )
r = - 11
For all parts of this question, use the function y + 2 = 3(x + 4)
Part A: Complete the x-y table:
i would start by simplifying the equation to get y by itself, you don't need to do this, but it makes it a little easier
y + 2 = 3 ( x + 4) distribute the 3 through the parenthesis
y + 2 = 3x + 12. subtract 2 from both sides
y = 3x +10
now to fill in the chart simply plug in the value of x to see what value of y it produces
y = 3(-2) +10
y = -6+10
y = 4
(-2,4)
y = 3(0) + 10
y = 0 + 10
y = 10
(0,10)
y = 3(2)+10
y = 6 + 10
y = 16
(2,16)
y = 3(4) + 10
y = 12 + 10
y = 22

I think it is No am not sure exactly
The expanded form of this number 570.086 is,
⇒ (5 × 100) + (7 × 10) + (8 × 1/100) + (6 × 1/1000)
What is Place value?The value represented by a digit in a number on the basis of its position in the number is called a Place value.
Given that;
The number is,
⇒ 570.086
Now, We can expand the number as;
⇒ 570.086
⇒ 500 + 70 + 00 + 8/100 + 6/1000
⇒ (5 × 100) + (7 × 10) + (8 × 1/100) + (6 × 1/1000)
Thus, The expanded form is,
⇒ (5 × 100) + (7 × 10) + (8 × 1/100) + (6 × 1/1000)
