A block of iron has dimensions of 1 cm x 2 cm x 5 cm and has a
mass of 799
What is its density? (V=lxwxh)

Answers

Answer:

79.9 units

Step-by-step explanation:

Hi there,

Before solving this problem, it is important to know the formula:

D = [tex]\frac{m}{v}[/tex].

D = density

m = mass

v = volume

Since we are given the mass and volume, we can simply enter these values into the formula to find the density of the block.

D = [tex]\frac{799}{10}[/tex]

D = 79.9

Therefore, the density of the block of iron is 79.9 units. I wrote units since you did not specify the unit for the mass. Hope this answer and explanation helps.

Cheers.

Franco read 5/8 of a chapter of his history book in 2/5 of an hour. At this rate, how many chapters of his history book can he read in 1 hour?

Answers

Answer:

12.5/8 or 1  4.5/8 so the simplified answer could be 1 2.25/4

Step-by-step explanation:

multiply 5/8 by 2.5 becuase 2x2.5=5

so you want to get 5/5 for a full hour

5x2.5=12.5 and keep the donominator the same

then simplify so 1 4.5/8

Step-by-step explanation:

Volume = Bh

Volume = (1/2 x b x h) h

Volume = (1/2 x 6 x 4) 10

Volume = 120

SA = 2B + Ph

SA = 2(1/2 x b x h) + (s + s + s)h

SA = 2(1/2 x 6 x 4) + (5 + 5 +6) 10

A new store is handing out small gifts to the customers who come in. Elizabeth is handing out pens of various colors.She has determined that the chance of a customer receiving a blue pen is 0.008.

It is very unlikely that a customer gets a blue tote bag, but it is very likely that a customer gets a blue pen.

It is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen.

Answers

Answer:

99% sure it's B !!!

Step-by-step explanation:

It is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen (Option B)

How can we interpret probability?

Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment.

Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively).

Since it is given that:

The chance of a customer receiving a blue pen = 0.008The chance of a customer receiving a blue tote bag = 0.04

Both probabilities are too close to 0, than 1. So they both are very unlikely to occur.

Thus, it is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen (Option B).

Facts:

Justin jogs 3 2/3 miles every morning

Jogs 4 6/10 miles every evening.

Miles jogged per day=?

To solve this question,add the 2 fractions.This makes sense  because let's say you ran 3 miles in the morning and 2 miles in the evening, nothing more nothing less, and you wanted to find how much you ran in a day, you'd add these 2 nummbers.

3 2/3 + 4 6/10

Step 1: Add the whole numbers

3 2/3 + 4 6/10

3+4= 7

7 + 2/3 + 6/10

Step 2: Find a common denominator between 10 and 3

10x1= 10

10x2= 20

10x3= 30 (works for both 3 and 10)

7 + __    +  __

     30        30

Step 3: Change the neumerators

Now when adding fractions this way, you have to multiply and change the neumerator:

In the 1st fraction, the original denominator was 3. And 3x10= 30, right? So you must also multiply the neumerator by 10 so that they are equivalent to each other

2x10= 20

In fraction #2, the neumerator was 6. 6x3= 18

7 + 20   + 18

     30        30

7+38/30= 7 38/30= 8 8/30 miles per day

The probability of landing on tales is 1/2 as shown in the right section.

Becuase it is an or and not an and... you have to add them together.

Which of the [outlined] sentences from "Reconstruction" by Frederick Douglass best expresses the central idea? The assembling of the Second Session of the Thirty-ninth Congress may very properly be made the occasion of a few earnest words on the already much-worn topic of reconstruction. [Seldom has any legislative body been the subject of a solicitude more intense, or of aspirations more sincere and ardent. ] There are the best of reasons for this profound interest. [Questions of vast moment, left undecided by the last session of Congress, must be manfully grappled with by this. ] No political skirmishing will avail. The occasion demands statesmanship. Whether the tremendous war so heroically fought and so victoriously ended shall pass into history a miserable failure, barren of permanent results,a scandalous and shocking waste of blood and treasure,a strife for empire, as Earl Russell characterized it, of no value to liberty or civilization,an attempt to re-establish a Union by force, which must be the merest mockery of a Union,an effort to bring under Federal authority States into which no loyal man from the North may safely enter, and to bring men into the national councils who deliberate and vote venomously, and who do not even conceal their hate of the country that conquered them; or whether, on the other hand, we shall, as the rightful reward of victory over treason, have a solid nation, entirely delivered from all contradictions and social antagonisms, based upon loyalty, liberty, and equality, must be determined one way or the other by the present session of Congress. [The last session really did nothing which can be considered final as to these questions. ] The Civil Rights Bill and the Freedmen's Bureau Bill and the proposed constitutional amendments, with the amendment already adopted and recognized as the law of the land, do not reach the difficulty, and cannot, unless the whole structure of the government is changed from a government by States to something like a despotic central government, with power to control even the municipal regulations of States, and to make them conform to its own despotic will. [While there remains such an idea as the right of each State to control its own local affairs,an idea, by the way, more deeply rooted in the minds of men of all sections of the country than perhaps any one other political idea,no general assertion of human rights can be of any practical value. ] To change the character of the government at this point is neither possible nor desirable. [All that is necessary to be done is to make the government consistent with itself, and render the rights of the States compatible with the sacred rights of human nature. ] Trade Policy: Export Subsidy Home exports guitars.
