I should return after 7.7 minutes later to bathtub.
What is bathtub?You want to turn the water off when the level in the bathtub is 8.5
66/8.5
7.7 minutes
A bathtub is a long, typically rectangular container that you sit in to bathe your body after filling it with water.
Let's start with the truth: Showers are cleaner than baths. Showers spray polluted water out of sight while distributing water evenly over your body.
Actually, there is nothing that sets one apart from the other. All of them include jets, bubbles, and frequently different colored lights and other decorations. They are all sizable hot water containers. Overall, the terms "whirlpool bath," "Jacuzzi," and "hot tub" all refer to the same thing.

Find the 10 th term of each geometric sequence. a₁₁ =-5, r=-1/2
The 10th term of the geometric sequence with a(11) = -5 and r = -1/2 is a(10) = 10.
A geometric sequence is a sequence of numbers where the nth term is obtained by multiplying the (n-1)th term by a constant, called a common ratio (r). Mathematically, it can be expressed as:
a(n) = a(n-1) . r
So, if a(1), a(2), a(3), ..., a(n) is a geometric sequence, then:
a(2) = a(1) . r
a(3) = a(1) . r
and so on.
In the problem, the given parameters are: a(11) = -5 and r = -1/2, and we need to find a(10).
Using the above recursion:
a(11) = a(10) . r
-5 = a(10) . (-1/2)
Multiply both sides by (-2)
-5 . (-2) = a(10) . (-1/2) . (-2)
a(10) = 10

Two vertices of $\triangle ABC$ are $A\left(3,\ 0\right)$ and $B\left(7,\ 3\right)$ . Find the coordinates of $C$ on the positive $x$ -axis such that the value of the perimeter of the triangle is twice the value of the area of the triangle.
The coordinate of C=(4,0).
What is Area of triangle?The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
Given:
ΔABC with
A(3, 0), B(7, 3)
let the coordinate of c(x, y)
Also, Perimeter of triangle = 2 * Area of triangle
Area of triangle=1/2 * b * h
Area=1/2 * 4 * 3
Area=1/2 * 12
Area=6 units
Perimeter= AB + BC + CA
Now,
Now, using distance formula
AB = √(7-3)² + (3-0)²
AB = √16+9
AB= 5 units
Perimeter of triangle=5+4+3
Perimeter =12
So, the coordinate of C=(0+4,0)

A new long-life tire has a tread depth of 7/16 inches, instead of the more typical 7/32 inches. How much deeper is the new tire?
Answer: The new tire is 7/32 of an inch deeper, or twice as deep.
Step-by-step explanation: The answer can be found by subtracting the old tire length from the new tire length. We must first find a common denominator. To do that, we multiply both the top and bottom of 7/16 by two and get 14/32. Now we subtract 7/32 (old tire) from 14/32 (new tire) to get 7/32.

Under her cell phone plan, Caroline pays a flat cost of $54.50 per month and $5 per gigabyte. She wants to keep her bill at $74 per month. Write and solve an equation which can be used to determine gg, the number of gigabytes of data Caroline can use while staying within her budget.
The required linear equation is of the form 54.5 + 5 g = 74 , and Caroline can use 3.9 gigabytes of data to stay within budget.
There are about one or two variables in a simple linear equation. In a linear equation, no variable can be multiplied by a numerical value that is greater than one used as the fraction 's denominator.
Let us consider that Caroline uses g gigabytes of data for the month.
Therefore total cost incurred by her in one month = 54.5 + 5g
She wants to keep the value of her monthly bill at $ 74.
Therefore we can write a linear equation to solve this problem:
54.5 + 5 g = 74
or, 5 g = 74 - 54.5
or, g = 19.5 ÷ 5
or, g = 3.9
Therefore Caroline can get maximum of 3 gigabytes of data if she wants to keep the budget below $74 .

He and two of his friends planted the remaining sutures during lunch. If each Person gets the same number of signatures, which inequality can Winston use to determine the minimum number of signatures each person should get so he can run for class president?
The inequality that Winston can use to determine the minimum number of signatures is 3x ≥ 57.
What is the inequality?The first step is to determine which inequality sign would be used.
The following are inequality signs and what they mean:
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
The sign that would be used is the greater than or equal to sign - ≥ . This is because the number of signatures can be either equal to 80 or greater than 80.

The solution of the equation 4/x+3=5 is at x = -11/5.

We have an equation 4/x+3=5.
As we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.
Therefore, the solution of the equation 4/x+3=5.
4/x+3 = 5
⇒ 4 = 5(x + 3) (multiplying both the sides by x + 3)
⇒ 4 = 5x + 15 (by distributive rule)
