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.

Answers

Answer:

Volume: 120

SA: 400

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

SA = (24 + 16) 10

SA = 40 x 10

SA = 400

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

Facts:

Last year, the tree was 5 11/12 feet long.

This year, the tree is 7 2/3 feet long.

How many feet did it grow?

Convert to decimals and subtract:

7 2/3= 7.66667

5 11/12= 5.9166667

7.66667- 5.916667= about 1.75, which becomes 1 3/4

It grew 1 3/4 feet

Step-by-step explanation:

The probability of rolling a 6 is 1/6 as shown in the left section.

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.

Therefore, the probability of rolling a 6 or landing on tails is 4/6.

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).

Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag. There is no evidence that this legend is true, and no one knows for certain who made the first flag, which had 13 stars and 13 stripes. However, we know for a fact that the first flag to have 50 starsthe one we have todaywas designed by a high school student. In 1958, Bob Heft was a 17-year-old student at Lancaster High School in Ohio. At that time, the United States had only 48 states but was on the verge of accepting two more: Alaska and Hawaii. The U.S. flag at the time had six neat rows of eight stars each. What would be the best way to add two more stars while keeping the arrangement neat and orderly? This was the question that Bobs history teacher posed to the class. The teacher gave the students an assignment: design a flag with 50 stars. Bob spent hours in the attic of his house, cutting up a 48-star flag and rearranging the stars until they fit just right. He was pleased with his solution to the problem, but his teacher found it less than perfect and gave him a B minus. Outraged, Bob told his teacher that he was going to send his design to his member of Congress, Walter Moeller. His teacher replied that if Bobs design was accepted as the new flag, he would be more than happy to change the grade to an A. A year later, Bob had graduated and was working as a draftsman when he received a call at work. He never would have imagined a call from President Eisenhowerbut that's who it was! Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag. Bob Heft was invited to Washington, D.C., for a ceremony during which his design was officially adopted as the new flag of the United States.Which statement best describes the authors viewpoint toward Bob Heft in A Flag with 50 Stars?Bob was not a very good student at Lancaster High School.Bob should not have contacted a member of Congress about a trivial matter.Bob's grade did not reflect the outcome of the story.Bob should not have spent so much time on his project.
