Please help I would be very greatful. On a coordinate plane, a solid straight line has a positive slope and goes through (0, 0.2

) and (3, 2.2). Everything to the right of the line is shaded. Which linear inequality is represented by the graph? y > Two-thirdsx – One-fifth y ≥ Three-halvesx + One-fifth y ≤ Two-thirdsx + One-fifth y < Three-halvesx – One-fifth

There are 28.35 grams in an ounce and 2.21 pounds in a kilogram. Miriam converted 7 kilograms to ounces, but her answer is not c

sergejj [24]

Answer: OPTION C.

Step-by-step explanation:

For this exercise it is important to remember the following:

$1\ kilogram=1,000\ grams$

Knowing this and based on the information provided in the exercise, you can make the conversion from kilograms to ounces. This is:

$(7\ Kg)(\frac{1,000\ gr}{1\ Kg})(\frac{1\ oz}{28.35\ gr})=246.913\ oz$

According to the exercise, Miriam's procedure was:

$(7\ Kg)(\frac{1,000\ gr}{1\ Kg})(\frac{28.35\ gr}{1\ oz})= 198,450\ oz$

So you can identify that she made a mistake.

Notice that:

1. Miriaim multiplied correctly.

2. Butt the third fraction should be $\frac{1\ oz}{28.35\ gr}$ and not $\frac{28.35\ gr}{1\ oz}$ .

What is the radical form of the expression?<br><br> (5x3y4)37<br> ↡

hram777 [196]

Option 4: $\sqrt[7]{125x^9y^{12}}$ is the right answer

Step-by-step explanation:

Given expression is:

$(\sqrt{5x^3y^4})^{\frac{3}{7}$

In order to convert an exponent into radical form, the power should be in the form of 1/x where x is any number

so,

in case of 3/7, it will be broken down

$(\sqrt{5x^3y^4})^{3*\frac{1}{7}}$

The 1/7 will be converted into base of radical while 3 will be he exponent

$\sqrt[7]{(5x^3y^4)^3}$

Multiplying exponents

$=\sqrt[7]{5^3x^{3*3}y^{4*3}}\\=\sqrt[7]{125x^9y^{12}}$

Hence,

Option 4: $\sqrt[7]{125x^9y^{12}}$ is the right answer

Ms. berkin is dividing her 4 1/2-foot by 6-foot bulletin board into 4 sections with ribbon stretched from each corner to the opp

Mnenie [13.5K]

Answer:

15 feet.

Step-by-step explanation:

A bulletin board has been shown in the figure below.

Where the width of the board AB = DC = $4\frac{1}{2}$ = 4.5 feet

and the length of the board AD = BC = 6 feet

As Ms. Berkin is dividing the board by stretching the ribbons to the opposite corners so the length of ribbons will be AC and BD.

In right angle triangle <em>ADC</em>, using Pythagorean Theorem,

$AC^2=AD^2+DC^2$ = $6^2+4.5^2=36+20.25=56.25$

$AC= \sqrt{56.25} = 7.5$ feet

Similarly in triangle <em>BDC</em>,

$BD^2=BC^2+DC^2 = 6^2+4.5^2=36+20.25 =56.25$

$BD=\sqrt{56.25} = 7.5$ feet

Thus, total length of the ribbon used = AC + BD = 7.5 + 7.5 = 15 feet

If 10x + 2 = 7, what is the value of 2x?

Julli [10]

For this case we have the following equation:

$10x + 2 = 7$

From here, we clear the value of x.

We have then:

$10x = 7-2\\10x = 5\\x = \frac {5} {10}\\x = \frac {1} {2}$

Then, we look for the value of 2x. We have then:

$2x = 2 \frac {1} {2}\\2x = \frac {2} {2}\\2x = 1$

Answer:

The value of 2x is given by:

$2x = 1$
