Answers

Answer:$44.69

Step-by-step explanation:

Original cost = $45.87

Cost with sales = 45.87 x 0.10 since 10% is 0.10 as a decimal

New cost = (45.87) - (45.87 x 0.10)

=$41.283

Cost with tax  = 41.283 x 1.0825       <- 8.25% is 0.0825 as a decimal

= $44.69

Answer:

$44.69

Explanation

10 Percent of $45.87 is 4.587 rounded to the nearest hundredth is $4.59.

$45.87 - $4.59 is $41.28

8.25% of $41.28 is 3.4056 rounded to the nearest hundredth is $3.41.

$41.28 + $3.41 is $44.69

What is the term that describes how a cell must maintain a stable environment? (in: regulating temperature)

Answers

Answer:

homeostasis

Step-by-step explanation:

Homeostasis refers to the body's ability to maintain a stable internal environment (regulating hormones, body temp., water balance, etc.).

Answer:

Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside. All living organisms, from plants to puppies to people, must regulate their internal environment to process energy and ultimately survive.

The maintenance of stable, constant, internal conditions is called homeostasis. ... Like the walls of a house, cell membranes protect the inside of cells and maintain homeostasis through molecular transport. Controlling how much of which molecules enter or leave a cell allows cells to function properly.

Multi step equations that equal 17 with fractions

Answers

Answer:

7/1 - 7/1 + 17/1 = 17

Step-by-step explanation:

The solution to the equation (x/6 - 4 + 2/3) = -1/2, using the LCD or clearing method, is x =17 by solving multistep equations that equal 17 with fractions

To solve this equation, use the LCD (Least Common Denominator) method to eliminate the fractions.

The LCD in this case is 6, as it is the smallest number that both 6 and 3 (the denominators of the fractions) can evenly divide.

Step 1: Multiply every term in the equation by 6 to clear the fractions:

[tex]6 \times (x/6 - 4 + 2/3) = 6 \times(-1/2)[/tex]

Simplifying the equation:

[tex]x - 24 + 4 = -3[/tex]

Step 2: Combine like terms on the left side:

[tex]x - 20 = -3[/tex]

Step 3: Isolate the x variable by adding 20 to both sides of the equation:

[tex]x - 20 + 20 = -3 + 20[/tex]

Simplifying further:

x = 17

Therefore, the solution to the equation [tex](x/6 - 4 + 2/3) = -1/2[/tex] is [tex]x = 17[/tex].

First off, skip the Y part since the answer you're looking for have nothing to do with it.

Find 20%of $2500 what is the answer

Answers

Answer:

20% of 2500 is 500

Step-by-step explanation:

Answer:

500

Step-by-step explanation:

We need to determine 20% of 2500 now and the procedure explaining it as such

Step 1: In the given case Output Value is 2500.

Step 2: Let us consider the unknown value as x.

Step 3: Consider the output value of 2500 = 100%.

Step 4: In the Same way, x = 20%.

Step 5: On dividing the pair of simple equations we got the equation as under

2500 = 100% (1).

x = 20% (2).

(2500%)/(x%) = 100/20

Step 6: Reciprocal of both the sides results in the following equation

x%/2500% = 20/100

Step 7: Simplifying the above obtained equation further will tell what is 20% of 2500

x = 500%

Therefore, 20% of 2500 is 500

need help on this I need all work shown as well, the subject is on similar triangles

Answers

Answer:

  10 in

Step-by-step explanation:

If you draw a line parallel to the side of the cone through the center of the 10-inch (radius) circle, you create a right triangle with one leg 10 inches and a hypotenuse of 20+10 = 30 inches. It is similar to the right triangle shown on the diagram with leg 10 inches. That  means the distance from the center of the 10-inch (radius) ball to the bottom of the cone is 30 inches.

Subtract from that the 10-inch radius and the 10-inch diameter of the two bottom balls shown, and you find the distance from the base of the smallest ball to the bottom of the cone is 30 -10 -10 = 10 inches.
