7. The resistance of dry human skin is about 500,000 ohms in wet, sweaty
human skin is about 1000 ohms. How much current passes across
someone's finger if they touch the leads of a 9 volt battery when their skin
is wet and dry?
Answer:
Step-by-step explanation:
1000 Ohms
R = 1000
V = 9
I = V / R
I = 9 / 1000
I = 0.009
500000 Ohms
V = 9
I = V/R
R = 500000
I = 9 / 500000
I = 0.000018

Answer:
134,000-X=Y
Step-by-step explanation:
you'll first have to solve how many categories there are, but since we don't know we'll use X, we already know that there is 134,000 books, but we don't know how many books are reference or other, so we use Y to represent that.
so it's
134,000-X=Y

Determine whether the following statement is true or false.
A proper use of units can help us to determine the meaning of the slope of a linear function.
Here we want to see if the statement:
"A proper use of units can help us to determine the meaning of the slope of a linear function" is true or false.
We will see that it is true.
First, a general linear equation can be written as:
y = a*x + b
Where a is the slope, x is the independent variable, y is the dependent variable, and b is the y-intercept.
The proper use of units is:
y and b must have the same units.
x can have any type of units
The slope must have the quotient between the units of y and the units of x.
Where the proper use of units means that we have the same units on both sides of the expression.
Now, assume that we know the units of y and x.
For example:
y is miles (then b is also in miles)
x is in hours
Then, with the proper use of units, we can see that the units of the slope are:
miles/hour, or miles per hour.
With this (only knowing the units of x and y) we can see that the slope will be a speed.
So yes, the proper use of units is really important, as this has a lot of information (particularly, the meaning of the slope in a linear equation)
Thus, the statement is true.

Some Word Problems
1. You are making sandwiches for a large crowd. All must be identical and must contain 2 slices of bread, 2 teaspoons mustard, 3 slices salami, 2 slices of cheese, 2 lettuce leaves, and 1 slice tomato.
You have on hand
2 loaves of bread, 20 slices each 3 pounds of cheese, each pound gives 16 slices 1 quart of mustard 60 slices of salami An unlimited supply of tomatoes from your garden 3 head of lettuce, approximately 15 leaves in each
How many sandwiches can you make?
For which ingredients is (are) there no leftovers?
In case you've forgotten your kitchen conversions: 1 quart = 4 cups; 1 cup = 16 tablespoons; 1 tablespoon = 3 teaspoons
We are to find how many sandwiches can be made and the ingredients that has leftovers
You can make 20 sandwiches
lettuce has 1 leftover and tomato has unlimited leftover
Recipe for Sandwiches:
Bread = 2 slices
Mustard = 2 teaspoons
Salami = 3 slices
cheese = 2 slices
Lettuce = 2 leaves
Tomato = 1 slice
3 pounds of cheese = 16 × 3 slices = 48 slices2 loaves of bread = 20 slices × 2 = 40 slices1 quart of mustard = 4 cups × 16 tablespoons × 3 teaspoons= 192 teaspoons
lettuce = 3 heads × 15 leaves= 45 leaves
Recipe available:
Bread = 40 slices
Mustard = 192 teaspoons
Salami = 60 slices
cheese = 48 slices
Lettuce = 45 leaves
Tomato = unlimited
Bread
Recipe available / original recipe
= 40 slices / 2 slices
= 20 servings
No leftovers
Mustard
Recipe available / original recipe
= 192/2
= 96 servings
No leftovers
Salami
Recipe available / original recipe
= 60 / 3
= 20 serving
No leftovers
Cheese
Recipe available / original recipe
= 48/2
= 24 servings
Lettuce = 45/2
= 24 remaining 1
leftover = 1
Tomato = unlimited leftovers
The ingredients available can only make 20 sandwiches equally

-10 is the value of the given polynomial.
What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.
First, we can simplify the polynomial by combining like terms:
[tex]2x^2y + 4x^2y + 3xy^2 - 5xy^2 - 3xy + y^2\\= (2x^2y + 4x^2y) + (3xy^2 - 5xy^2) + (-3xy + y^2)\\= 6x^2y - 2xy^2 - 3xy + y^2[/tex]
Now, to evaluate for x = 1 and y = -2, we substitute those values into the simplified expression:
[tex]6(1)^2(-2) - 2(1)(-2)^2 - 3(1)(-2) + (-2)^2\\= 6(-2) - 2(4) + 6 + 4\\= -12 - 8 + 6 + 4\\= -10[/tex]
Therefore, the value of the polynomial for x = 1 and y = -2 is -10.
