Answer:

true

Step-by-step explanation:

Natural numbers are numbers naturally occurring in nature like 1, 2, 3, 4, 5, 6, 7, 8, 9 . . .

Whole numbers are numbers that are whole, like 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 . . . (the only difference is that there is a 0 included)

Integers include negative and positive numbers like -3, -2, -1, 0, 1, 2, 3, 4 . . .

Rational numbers are include all of the above AND anything that can be turned into a fraction, like fractions and decimals (that have an end) like 0.625, -0.5, 1, 4, 1/4, 6/15, 4.8, etc.

So in this case, yes, 0.5 is a rational number.

Answer:

Price of one pound of mercury

[tex]x=\$ 2.06[/tex]

Price of one cubic inch of mercury

[tex]z=\$1.0[/tex]

Step-by-step explanation:

From the question we are told that

Mass of mercury [tex]M= 76pound[/tex]

Price of 76 pound [tex]P=\$162[/tex]

Density of mercury is [tex]\rho=13.534 g/cm3.[/tex]

Generally the cost of one pound of Mercury x will mathematically be given as

 [tex]x=\frac{162}{76}[/tex]

 [tex]x=\$ 2.13[/tex]

Generally the cost of one gram of Mercury G will mathematically be given as

 [tex]1pound = 453.92g[/tex]

 [tex]G=2.06/453.93\\G=\$4.6*10^-^3[/tex]

Generally the cost of one cubic centimetre of Mercury c will mathematically be given as

 [tex]13.5= 1cm^3\ of\ Mercury[/tex]

 [tex]c=\$6.33*10^-^2[/tex]

Generally the cost of one cubic inch of Mercury z will mathematically be given as

 [tex]z=0.0614*16.4[/tex]

 [tex]z=\$1.0[/tex]

Answer:

metric

Step-by-step explanation:

The metric system is divided up by fractions such as ¼ and ½.

The set of standard units used to measure length, weight, area, and capacity is known as the metric system of measurement in mathematics. As it uses numbers in powers of 10, it is based on the decimal system.

In the metric system:

Although it is not strictly forbidden, using fractions such as ¼ and ½ of a measurement is typically not necessary.

As opposed to the American Customary System.

Therefore, the metric system is divided up by fractions such as ¼ and ½.

Answer:

Yes, she is correct

Step-by-step explanation:

All you really have to do is multiply 1/5 and 3/4. We can separate her backyard in 5 equal parts. In one of those parts, we have her garden, and we break it down into 4 pieces, and make three of those tomato gardens. Now if we break all 5 parts of her backyard into 4 pieces, we can double check our answer, and see that there are 20 pieces, but only 3 have tomatoes. Of course, that's only to double check, but you could also use this method as a model.

Answer:

Kiara is correct

.............

Kiara says that the slope of the line between points B and C is the same as the slope of the line between points A and B is Correct.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

From the figure

Slope between A and B = rise/ run 3/3 = 1

and, slope between B and C = 5/5 = 1

So, the slope between A and B is same as the slope between B and C.

Hence, Kiara has correct statement.

$19.03

Step-by-step explanation:

Okay, this is a standard percentage problem, so learning how to do this is necessary. First, we have to find what 6% of $17.95 is, since of is our keyword and that means to multiply, and percentages turn into decimals:

17.95 x 0.06 = 1.08

So we have our tax, then we have to add that to our original price to get the whole thing:

17.95 + 1.08 = 19.03

So the total sale price is $19.03

-5 = w

Step-by-step explanation:

3(2-5) – (4w=11)

Distributive property

6 - 15 - 4w = 11

Combine like terms

-9 - 4w = 11

Add 9 on both sides

-9 + 9 - 4w = 11 + 9

-4w = 20

Divide by -4 on both sides to isolate the variable

-4w/-4 = 20/-4

w = -5
