Pls Help. Cindi Wants To Cover The Top And Sides Of This Box With Glass Tiles Thatare 1 Cm Square. How

Answers

Answer 1

Answer:

300 square centimeters

Answer 2

Surface area of box:

= 2(lb + bh +hl)

= 2(20×15 + 15×9 + 9×20)

= 2(300 + 95 + 180)

= 2 × 575

= 1,150 cm³

Area of tiles:

= 1 × 4 = 4 cm

No of tiles:

= 1,150/4

= 287.5 = 288

Total 288 tiles will be needed

What is value?

Value is an important concept in economics, finance, and accounting. It is the worth of a thing, such as a product, service, or currency. Value can be determined by the amount of goods or services it can exchange for, or the amount of money it can produce. Value is subjective, so it is up to the individual to decide what is valuable to them. Value is also a measure of the relative worth of a good or service, and it can have an effect on the price of a good or service. Value is an important concept to understand in economics, finance, and accounting.

The absolute value of m can be calculated by taking the distance between m and 0, regardless of whether m is negative or positive. For example, if m is -7, the absolute value of m is 7, since the distance between -7 and 0 is 7. If m is 3, then the absolute value of m is also 3, since the distance between 3 and 0 is also 3.

Answer:

C

Step-by-step explanation:

The number of hours to fill the pool will be 180. Then the correct option is C.

What is Algebra?

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

The table below shows how the number of hours needed to fill a pool depends on the flow rate of the hoses used to fill it.

Flow rate (gal/hr)                   Time (hours)

           x                                          y

         60                                       300

         45                                       400

         36                                       500

         30                                       600

Then the amount of liquid in the pool will be

⇒ 60 x 300

⇒ 18,000 gallons

If this much liquid is filled with hose that has a rate of 40 gallons per hour, then the number of hours will be

⇒ 18,000 / 40

⇒ 450 hours

Then the number of hours if two hoses are used to fill the pool that one has a rate of 40 gallons per hour and one has a rate of 60 gallons per hour will be

1/T = 1/450 + 1/300

1/T = 1 / 180

  T = 180 hours

Then the number of hours to fill the pool will be 180.

Then the correct option is C.

support
75% of ____>50% of _____
refute
75%of ____ < 50% of_____

Answers

Answer:

it is not always true that 75% of a number will be greater than 50% of any other number

Step-by-step explanation:

Leila's statement is not true. It is possible for 50% of a number to be greater than 75% of another number.

For example, consider the numbers 10 and 100. 50% of 10 is 5, and 75% of 100 is 75. In this case, 50% of 10 (5) is greater than 75% of 100 (75).

Here's another example: 50% of 20 is 10, and 75% of 30 is 22.5. In this case, 50% of 20 (10) is again greater than 75% of 30 (22.5).

Therefore, it is not always true that 75% of a number will be greater than 50% of any other number.

What do you meant by depend and independent variable ?

It is the cause that is the independent variable. Its worth is unrelated to other study variables. The effect serves as the dependent variable. The independent variable's modifications determine its value. It is a thing that is dependent on other things. The amount of study you did, how much sleep you had the night before the test, or even how hungry you were when you took it.

Could all affect your test result, which makes it a dependent variable. The dependent variable is impacted by the independent variable. For instance, your exam results are influenced by how much sleep you get (an independent variable) (dependent variable). This is understandable, but Ex. How much sleep you get depends on your test results.

The equation that correctly solves the formula of r is r = [tex]\sqrt{\frac{A}{4\pi } }[/tex]

How can the value of r be computed?

The concept here is the concept of subject of the formula.

The variable being calculated is the formula's subject. On one side of the equals sign, it is identifiable as the letter on its own. For instance, the subject of the formula for the area of a rectangle is A = b h (area = base height).

The formula given was A=4πr^2h, then we can r the subject of the formula as
