Answer:
r = -39
Step-by-step explanation:
So we are trying to solve the equation for r.
-6(2r + 8) = -10(r - 3)
Divide both sides by -2. (This will make distributing much easier.)
3(2r + 8) = 5(r - 3)
Distribute the 3 on the left side and the 5 on the right side,
6r + 24 = 5r - 15
Subtract 24 from both sides.
6r = 5r - 39
Subtract 5r from both sides.
r = -39
So now we have solve the equation.

2.25
Step-by-step explanation:
in order to find the scale factor from A to B you need to divide B by A. 13.5÷6=2.25. 11.25÷5=2.25 and 4.5÷2=2.25.
therefore the scale factor is 2.25 because when you multiply the sides from A by 2.25 you get the length of the side from B.

prove the divisibility rule by three, which states that a number is divisible by 3 if and only if the sum of its digits is divisible by 3.
The divisibility rule for 3 on any integer number is proven in the detailed explanation of the solution.
Given a non-decimal number, n.
Suppose n may be divided by 3.
n should be thought of in terms of its digits as
n = d × 1 × 10⁽ⁿ⁻¹⁾⁽ⁿ⁻¹⁾ + d × 2 × 10⁽ⁿ⁻²⁾ + ... + d × m × 10⁰
where d 1, d 2,..., d m are its digits and m is the number of digits in n.
The result of the preceding equation with n = 3k is
3k = d × 1 × 10(m-1) + d × 2 × 10(m-2) +... + d × m × 10(m-0)
3000 is subtracted from both sides of the equation, giving us
0 = d × 1 × 10⁽ⁿ⁻¹⁾⁽ⁿ⁻¹⁾ + d × 2 × 10⁽ⁿ⁻²⁾ + ... + d × m × 10⁰
We obtain by adding 3k to both sides of the equation.
3k = d × 1 × 10⁽ⁿ⁻¹⁾+ d
The divisibility rule is a heuristic for determining if two positive integers can be divided evenly (i.e. there is no remainder left over). For instance, determining if a number's last digit is 2, 4, 6, 8, or 0 makes it simple to determine whether it is even.
By examining the digits of the number, a divisibility rule provides a simple shorthand for determining if an integer is divisible by a particular set of factors without actually doing the division. This page only offers recommendations and examples for decimal, or base 10, numbers despite the fact that there are distinct divisibility tests for numbers in each radix or basis.

How are these two expressions equivalent?
The expressions In(√2+2) and - In(1-1/√2) are not equivalent.
To determine whether the two expressions are equivalent, we need to evaluate each expression and compare the results.
Expression 1: In(√2+2)
The square root of 2 (√2) is an irrational number approximately equal to 1.414.
Adding 2 to √2 gives us approximately 1.414 + 2 = 3.414.
Taking the natural logarithm (In) of 3.414 will give us the value of the expression.
Expression 2: - In(1-1/√2)
To evaluate - In(1-1/√2), we need to simplify it further.
Let's start by simplifying 1-1/√2:
1 - 1/√2 = (√2/√2) - (1/√2) = (√2 - 1)/√2
Taking the natural logarithm (In) of (√2 - 1)/√2 will give us the value of the expression.
To determine if the two expressions are equivalent, we would need to evaluate the numerical values of In(√2+2) and - In(1-1/√2). However, without the specific values of √2, we cannot compare the results directly.
Therefore, we cannot determine the equivalence of the two expressions without knowing the specific value of √2.

Austin found that the volume of a tennis ball is 36 cubic cm. He has a cylindrical container with a radius of 6 cm and a
height of 20 cm. Will Austin be able to fit three tennis balls into the container? How do you know?
Answer:
Yes, 3 balls will fit; the ball radius is smaller than the container radius, and the height is more than 4 times the ball diameter.
Step-by-step explanation:
We can compare the radius of a tennis ball to the radius and height of the cylinder to see if the balls will fit.
The volume of a sphere is given by ...
V = 4/3πr³
Solving for radius, we find ...
r = ∛(3V/(4π))
For the given ball volume of 36 cm³, the ball radius is found to be ...
r = ∛(3·36/(4π)) = ∛(27/π) ≈ 2.05 . . . cm
The radius of the container is 6 cm, almost 3 times the radius of a ball, so we know 3 tennis balls will fit in one layer in the container. Actually, the attached figure shows that 5 tennis balls will fit in one layer in the container.
The height of the container, 20 cm, is almost 10 times the radius of the tennis ball, 5 times the diameter, so we can get at least 5×5 = 25 balls in the container.
_____
Additional comment
The height of the container is 20/(2·2.05) ≈ 4.88 times the diameter of the tennis ball. When spheres are packed, each layer after the first takes additional height of at most √3/2 ≈ 0.87 times the diameter of the sphere. That means we can pack 5 layers of tennis balls in the container and have room left over.

The polynomial expression that represents the perimeter is (3x^3 +3x -148)ft and the value is 182ft
what is a polynomial?Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable.
Perimeter of the triangle is the sum of the sides of the triangle which is = 2x^2 -120 + x^2 -5x +8x -28
Perimeter = (3x^2 +3x -148)ft
when x = 10
Perimeter = 3(10)^2 +3(10) -148 = 182ft

Ty
{x 1
O {y|1 < y<5}
{x x is a real number}
O {yly is a real number}
6
5
Step-by-step explanation:
the domain is the interval or set of all valid input values (values of x).
while the range is the interval or set of all valid result values (y values).
so, we don't need to look at the answer options dealing with y. the domain only concerns x.
and when you look at the graph it shows you that every number on the x-axis from all the way to the left to all the way to the right is valid (from -infinity to +infinity).
and the function itself (the cubic root of x) did not provide any theoretical limits. you can take the cubic root from any number, positive or negative.
therefore, the third answer option is correct (all x, where x is a real number).
The domain of the function is the set of all real numbers, written as:
D: {x| x ∈ R}
How to find the domain of a function?
The domain of a function f(x) is assumed to be the set of all real numbers, and then we remove the problematic points.
Problematic points can be zeros in denominators, or negative arguments in square roots, for example.
In this case, our function is:
f(x) = ∛(x - 1) + 3
As you may know, we can input any real value in a cubic root and it will not generate any problem, and we don't have any denominator here, so there are no problematic points.
Thus, the domain of this function is just the set of all real values, written as:
D: {x| x ∈ R}

Two homebuyers are financing $137,000 to purchase a condominium. They obtained a 15-year, fixed-rate loan with a rate of 5.05%. They have been given the option of purchasing up to four points to lower their rate to 4.81%. How much will the four points cost them?
$1,370
$1,730
$4,580
$5,480
The cost of four points is:4 x $1,370 = $5,480Thus, the four points will cost the homebuyers $5,480.
Points can help lower mortgage rates on fixed-rate loans. The concept of points, which are basically prepaid interest, is a little complicated.
Each point is worth one percent of the loan amount, and paying points can lower your interest rate by a certain amount, typically about one-eighth to one-quarter of a percentage point.
The cost of points in the given scenario can be found using the following steps:
The loan amount to purchase a condominium is $137,000. The homebuyers obtained a 15-year fixed-rate loan with a rate of 5.05%.
If the homebuyers opt for four points, their loan rate will decrease to 4.81%.
To figure out how much the points will cost the homebuyers, we must first determine the cost of one point. Since one point is equal to 1% of the loan amount, one point on a $137,000 loan is:1% of $137,000 = $1,370

Rent for a 3 bedroom apartment is regularly $936 per month. Apartment management is offering one month free. If you sign a one year lease and apply the free month equally across months, how much is your new, monthly lease amount
The rent for The new monthly lease amount is $858.
To find out the new monthly lease amount, we need to take into account that there is one month free, which we need to apply to all the months of the lease period.
A one-year lease is for 12 months.
The total rent amount for 12 months = Regular rent for 12 months - One-month free rent= $936 × 12 - $936 = $11232 - $936= $10296
The free rent is distributed equally across the 12 months:$936 ÷ 12 = $78
The new monthly rent amount is the total rent amount for 12 months divided by the number of months:
Total rent amount for 12 months = $10296
New monthly lease amount = Total rent amount for 12 months ÷ 12
New monthly lease amount = $10296 ÷ 12
New monthly lease amount = $858
Therefore, the new monthly lease amount is $858.
