TRUE statements regarding the transmission of pathogens via environmental surfaces are the statements in option A and B.

Pathogens can be referred to as microscopic organisms which can cause diseases and illness. They are bacteria, fungi, virus or other disease causing organisms.

These pathogens can be transmitted via environmental surfaces especially by coming in contact with contaminated surfaces. Some pathogens survive longer on surfaces, while some only survive for few minutes.

If someone is placed in a room previously occupied by an infected person, the chances of contacting that same disease is high.

Thus, the statements that are TRUE regarding the transmission of pathogens via environmental surfaces are the statements in option A and B.

Answer:

1/2 feet

Step-by-step explanation:

1/4 of 2 feet is 1/2

There are 1/2 inches long is each Handle.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Each Handle is 1/4 the width of the handlebars.

And, Width of Handlebar is 2 ft

Hence, Lenght of each Handle is,

⇒ 1/4 of 2

⇒ 1/4 x 2

⇒ 1/2 feet

Thus, There are 1/2 inches long is each Handle.

879,000 square feet  is the lateral surface area of the pyramid

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The lateral surface area of a square pyramid can be calculated using the formula L = (1/2)Pl

where P is the perimeter of the base and l is the slant height of the pyramid.

Since the base of the pyramid is a square, the perimeter is 4 times the length of one side, or 4 × 750 = 3000 feet.

To find the slant height, we can use the Pythagorean theorem with one leg equal to half the length of the base (375 feet) and the other leg equal to the height (450 feet):

l =√375² + (450)²

= 583.095 feet

Therefore, the lateral surface area is:

L = (1/2) × 3000 × 583.095

= 879,000 square feet

Hence,879,000 square feet  is the lateral surface area of the pyramid

whenever you see this kind of question you don't need to start doing all the expressions, but look at the first and last numbers of the answer, the ones that cannot be changed (have no x or y or have those that cannot be changed in this expression):

the answer can't be a or c because in the given expression we can find 3x²y² and that's the only number where we can find x²y², so it cannot be changed. (you'll have 3x²y² in the answer)

now let's look at the last digit, that doesn't have a x or a y:

in b and d we can find 2 different results so this can determine which answer is correct:

let's look back at the given expression: -7+4= -3

Step-by-step explanation:

This type of problem is a permutation problem. Permutation is the arrangement of a set with certain order. In the problem, if there are 9 members, and 3 positions are available without repeating, we can write the expression as 9P3 - 3 non repeating positions in a set of 9 elements. By evaluating, we will have 9! / (9-3)! = 504. The answer is 504.

Answer:

Principal is the money that you originally agreed to pay back. Interest is the cost of borrowing the principal.

Step-by-step explanation:

First, calculate the interest portion of the payment by multiplying the mortgage balance by the annual interest rate. Then divide the result by 12, for the number of months in the year:

The numbers that the product is 26 and one of the numbers is one larger than six times the other number are 2 and 13.

The product of two numbers is 26.

let the two numbers be x and y.

Therefore,

xy = 26

One of the numbers is one larger than six times the other number. Therefore,

x = 1 + 6y

Hence,

xy = 26

(1 + 6y)y = 26

y + 6y² = 26

6y² + y - 26 = 0

using quadratic formula,

[tex]\frac{-b + \sqrt{b^{2} -4ac } }{2a}[/tex]

where

a = 6

b = 1

c = - 26

Therefore,

y = 2 or - 13 / 6

We can only use the positive value.

Hence,

2x = 26

x = 26 / 2

x = 13

Answer:

The answer is 60

By definition, the distance between two points is always positive, so the correct option is D.

Let's say that our plane has rectangular coordinates, so it would be something like a xy-plane.

Each point has 2 coordinates, so we can write:

A = (x₁, y₁)

B = (x₂, y₂)

The distance between the points is given by:

[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

As you can see, the distance is defined as positive (indifferent of the coordinates of the points).

So the correct option is D, the distance is always positive.
