7. Find the circumference of a circle whose diameter is 3.2 meters. Round to the nearest tenth.

vodka [1.7K]

Answer:

C. 10.0 m

Step-by-step explanation:

$C=2\pi r$

radius is half of diameter

$r = \frac{d}{2} \\r=\frac{3.2}{2} \\$

$C= 2 (3.14) \frac{3.2}{2}$

$C= (3.14)3.2\\C=10$

Determine whether each expression is equivalent to

larisa [96]

The algebraic expressions, $x + x + y + y + y + y - 5 + x + x + x + 8 - 4y$ and $5x + 3$ are equivalent to $2x + 4y - 5 + 3x + 8 - 4y$

To determine whether each expression is equivalent to $2x + 4y - 5 + 3x + 8 - 4y$ , apply the knowledge of algebra to solve each of the following in it's simplest form.

First, simplify $2x + 4y - 5 + 3x + 8 - 4y$ as follows:

Add like terms

$2x + 4y - 5 + 3x + 8 - 4y\\2x + 3x + 4y - 4y - 5 + 8\\5x + 3$

Next, compare or simplify where necessary each of the given algebraic expressions with $5x + 3$

First Option

$x + x + y + y + y + y - 5 + x + x + x + 8 - 4y$

Add like terms together

$2x + 4y - 5 + 3x + 8 - 4y\\2x + 3x + 4y - 4y -5+8\\5x + 3$

Therefore, $x + x + y + y + y + y - 5 + x + x + x + 8 - 4y$ is equivalent to $2x + 4y - 5 + 3x + 8 - 4y$

Check the box for YES.

Second Option:

$6xy + 3 - 4y$ (cannot be simplified further)

$6xy + 3 - 4y\neq 2x + 4y - 5 + 3x + 8 - 4y$

Therefore:

Leave the box BLANK for NO.

Third Option:

$-8y + 5x - 3$ (cannot be simplified further)

$-8y + 5x - 3 \neq 2x + 4y -5 + 3x + 8 - 4y$

Therefore:

Leave the box BLANK for NO.

Fourth Option:

$5x + 3$

$5x + 3 = 2x + 4y - 5 + 3x + 8 - 4y$

Therefore:

Check the box for YES.

Thus, the algebraic expressions that are equivalent to $2x + 4y - 5 + 3x + 8 - 4y$ are:

$x + x + y + y + y + y - 5 + x + x + x + 8 - 4y$

$5x + 3$

The cost to a store for an MP3 player is $60. The selling price is $105. A classmate says that the markup is 175% because $105/$

myrzilka [38]

Here are the steps, and remember to pay closely attention to the wording of the question. In this case, you have to find the percentage, and not the actual price.

First, calculate the markup in absolute terms: 

$105 - $60 = $45 

Then find the relative markup over the original price, or the markup rate: ($45) is (some percent) of ($60), or: 

45=(x)(60) 

So the relative markup over the original price is: 

45 ÷ 60 = x = 0.75 

Since x stands for a percentage, you need to remember to convert this decimal value to the corresponding percentage. 

The markup rate is 75% The selling price minus the cost to the store should be in the numerator and $60 should be in the denominator. So, the percent of markup is 75%.

Therefore, your classmate not correct.
