What is a Sales tactic?Sales tactics are those actions that are designed to build trust with potential customers and inspire to buy with confidence.
An installment purchase agreement is a type of contract that is used to finance the purchase of assets. The buyer pays the seller the full purchase price over time through a series of partial payments under the terms of such an agreement. Interest, whether stated or implied, is included in the payments.
Installment payments are when a customer pays a bill in small amounts over a set period of time.
Therefore, Option (d) is correct.

The perimeter of a rectangular lot is 86 feet. The
length is 19 feet greater than the width. Find the
length and width.
Answer: width would be 7 feet and the length would be 26
Step-by-step explanation:
width : w
length: 19 +w
2l + 2w = 66
2(19+w) + 2w= 66 distribute
38 + 2w + 2w = 66 add the w values
38 + 4w =66 subtract 38 from both sides
4w = 28 divide by 4
w= 7
19+7= 26

Rearrange the formula for y2
Answer:
y2 = m(x1 - x2)+ y1
Step-by-step explanation:
m = y2 - y1 / x1 - x2
m(x1 -x2) = y2 -y1
y2 = m(x1 - x2)+ y1
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
Multiply both sides by (x2 - x1)
m(x2 - x1) = y2 - y1
Add y1 to both sides
m(x2 - x1) + y1 = y2
y = m(x2 - x1) + y1

A stone is dropped into a barrel of water and sinks to the bottom. The ball is completely covered by water. By how much does the water rise in the barrel? I WILL GIVE BRAINLIEST!!! PLEASE HELP!!!
Answer:
Answer: 5/12 or approx. 0.42
Step-by-step explanation:
The ball will displace as much water as its volume.
Meaning, the volume of the ball and the volume of the increase in water in the barrel will be equal.
Volume of a sphere:
[tex]V_s=\frac{4}{3} \pi r^3[/tex]
The radius is half the diameter. The diameter of the sphere is 10, thus:
[tex]r = d/2 = 10/2 = 5[/tex]
5^3 = 5*5*5 = 25*5 = 125
[tex]V_s=\frac{4}{3} \pi * 5^3=\frac{4}{3} \pi * 125[/tex]
The volume of a cylinder, which will be the shape of the increase in water, is the following:
[tex]V_c=\pi r^2 h[/tex]
We know the radius r, as we know the diameter.
[tex]r=d/2=40/2=20[/tex]
[tex]V_c=\pi r^2 h=\pi h * 20^2 = \pi h * 400[/tex]
We are looking for the height of the cylinder, h, as that will be the height of the water rise.
Since we know these 2 volumes are the same, we'll set them equal to each other and solve the equation:
[tex]V_s = V_c[/tex]
[tex]\frac{4}{3} * 125 * \pi = 400 * h * \pi[/tex]
We can get rid of pi by dividing both sides by pi:
[tex]\frac{4}{3} * 125 = 400 * h[/tex]
And now divide both sides by 400:
[tex]\frac{4}{3} * \frac{125}{400}= h[/tex]
Just reversing it and putting h to the left:
[tex]h = \frac{4}{3} * \frac{125}{400} = \frac{4 * 125}{3 * 400}[/tex]
I see that I can divide both the numerator and the denominator by 4:
[tex]h =\frac{125}{3 * 100}= \frac{125}{300}[/tex]
I'll now divide both the numerator and the denominator by 25 to simplify the expression:
[tex]h=\frac{125}{300} =\frac{125 / 25}{300 / 25} = \frac{5}{12}[/tex]
Answer: The water rises by 5/12 (five twelfths).
If I want an approximate decimal answer, I can simply run this expression in a calculator:
[tex]\frac{5}{12}[/tex] ≈ [tex]0.416666667[/tex] ≈ [tex]0.42[/tex]
The amount of water rise is 0.42 and this can be determined by using the formula of the volume of the sphere and the cylinder.
Given :
A stone is dropped into a barrel of water and sinks to the bottom.
The ball is completely covered by water.
The following steps can be used in order to determine the water rise in the barrel:
Step 1 - The formula of the volume of a sphere is used in order to determine the water rise in the barrel.
Step 2 - The volume of a sphere is given below:
[tex]\rm V_s=\dfrac{4}{3}\times \pi \times r^3[/tex]
Step 3 - Substitute the values of the known terms in the above expression.
[tex]\rm V_s=\dfrac{4}{3}\times \pi \times \left(\dfrac{10}{2}\right)^3[/tex]
Step 4 - Simplify the above expression.
[tex]\rm V_s = \dfrac{4}{3}\times \pi \times 125[/tex] --- (1)
Step 5 - The volume of the cylinder is given below:
[tex]\rm V_c= \pi\times \left(\dfrac{40}{2}\right)^2\times h[/tex] --- (2)
Step 6 - Equate expression (1) and (2) in order to determine the value of 'h'.
[tex]\dfrac{4}{3}\times \pi \times 125= \pi \times 400 \times h[/tex]
Step 7 - Simplify the above expression.
[tex]\rm h = \dfrac{4\times 125}{3\times 400}[/tex]
h = 0.42

used to have a square garage with ft of floor space. recently built an addition to it. The garage is still a square, but now it has 50% more floor space. What was the length of one side of the garage originally? What is the length of one side of the garage now? What was the percent increase in the length of one side?
Answer:
Length of the original square garage = 16.7ft
Length of the new square garage= 20.5ft
Percentage increase in the length of the side = 23%
Step-by-step explanation:
Yossi used to have a square garage with 280 ft? of floor space. He recently built an
addition to it. The garage is still a square, but now it has 50% more floor space. What was the length
of one side of the garage originally? What is the length of one side of the garage now? What was the
percent increase in the length of one side?
Area of the original square garage = 280ft²
Area of a square = length²
280ft² = length²
Find the square root of both sides
√280ft² = √length²
16.7ft = length
Length of the original square garage = 16.7ft
Area of the new square garage = 280ft² + 50% of 280ft²
= 280ft² + 0.5 × 280ft²
= 280ft² + 140ft²
= 420ft²
Area of a square = length²
420ft² = length²
Find the square root of both sides
√420ft² = √length²
20.5ft = length
Length of the new square garage= 20.5ft
Percentage increase in the length of the side = (new - old) / old × 100
= (20.5 - 16.7) / 16.7 × 100
= 3.8 / 16.7 × 100
= 0.23 × 100
= 23%
Percentage increase in the length of the side = 23%

Is the square root of 58 a rational number
Answer:
The square root of 58 is a rational number if 58 is a perfect square.
Step-by-step explanation:
It is an irrational number if it is not a perfect square. Since 58 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 58?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.
is this what you needed or
The square root of the number is A = √58 is not a rational number
Given data ,
Let the first number be represented as p
where the value of p = 58
Now , the square root of the number is expressed as
A = √58
The radical form of a number refers to expressing a number using a radical symbol (√) to represent a root.
It is used to express the roots present in the number.
So , A = √58
On simplifying , we get
A = 7.6157731058639082856614110271583...
On further simplification , we get
A = the square root of 58 is not a rational number
Hence , the square root of 58 is an irrational number because it cannot be expressed as a fraction of two integers
