1. 28/15 as a decimal is 1.86666666666667 

2. 
the number is divisible by 3. 

Additionally, we know 120,000 is divisible by 3, 18,000 is divisible by 3, 420 is divisible by 3, and 15 is divisible by 3.

I hope this helps! I didn't do the last one my friend did but he thinks it's right. Please correct me if wrong.

At a carnival game, you randomly throw two darts at the board and break two balloons out of 15. What is the probability that both the balloons you break are purple? Write your answer as a fraction or percent rounded to the nearest tenth. (3 red, 4 blue, 2 green, 2 yellow, 4 purple)

Add up the total number of balloons (15) there are 4 purples so the probably of you getting purple at all is 4/15. consider that after you hit the first purple, your odds decrease to 3/14.

Compute and compare the side lengths of the two figures. Does this support an argument claiming that they are congruent? What else must be true to say two polygons are congruent?

The side lengths of the two figures can be calculated with the distance formula:

 √ (x1 - x2)² + (y1 - y2)²        

AB = √13  

BC = √13      

CD = √13    

DA = √13  

A'B' = √13      

B'C' = √13      

C'D' = √13      

D'A' = √13

They are all the same lengths. This supports an argument claiming that they are congruent because if the sides are congruent, then the two polygons are congruent.

Something else that must be true to say that two polygons are congruent is that the angles have equal measures.

Hope this helps! :)

When you divide a whole number by a decimal less than 1, the quotient is greater than the whole number. Why?

Dividing is the action of slimming a number down to a smaller size. When you divide a whole number by a decimal less than 1 the quotient is greater than the whole number because the that is how many times the quotient is a part of the whole number. For instance, you divide 100 by 4, you will get a quotient of 25. There are 4 parts of 25 to be equal to 100.

I hope this helps you!

Joseph received a $20 gift card for downloading music. Each downloaded song costs $1.29. Explain how to write and solve an inequality that can be used to determine the number of songs that he can purchase. Interpret the solution.

Let x be the number of songs downloaded.
Each song is $1.29; the total cost would be found by multiplying the cost by the number of songs, or 1.29x.
This cannot be more than 20, so we set this less than or equal to 20:
1.29x ≤ 20.

To solve this, we divide both sides by 1.29:
 \frac{1.29x}{1.29}  ≤  \frac{20}{1.29} ;
x ≤15.5.

We cannot download half of a song, so we round this down to 15 (although the number rounds up mathematically, he would not have enough money to download 16 songs). This means he can download at most 15 songs.

The lengths of three sides of a triangle are given. Determine whether each triangle is a right triangle. 1. 14 m, 5 m, 4 m 2. 3 in., 4 in., 5 in. Are these right triangles?

In a right triangle, the hypotenuse is always the longest side.  Plus, the hypotenuse squared has to equal the sum of the squares of the other 2 sides.  For the first "triangle" above: does 14 ^{2} =5 ^{2} +4 ^{2} ?  Let's check.  196 = 25 + 16 so does 196 = 41?  Obviously not.  So that is not a right triangle.  Let's check the second one the same way.  Does 5 ^{2} =3 ^{2} +4 ^{2} ?  25 = 9 + 16.  Does 25 = 25?  Of course it does!  So 1 is not a right triangle, but 2 is!

Jorge needs to ship a thin metal rod to a metalworking shop. The only boxes available for shipping are 7-inch cubes. To the nearest inch, what is the length of the longest metal rod that can be sent? 11 inches 12 inches 13 inches 14 inches

Answer:

The length of the longest metal rod that can be sent is 12 inches.

Step-by-step explanation:

As given, the only boxes available for shipping are 7-inch cubes. As Jorge needs to ship a thin metal rod to a metalworking shop, he will put the rods diagonally or space diagonally in the box.

The space diagonal of a cube can be found by the formula :

D=\sqrt{x^{2}+x^{2}+x^{2} }

= \sqrt{3} x

Here, x is 7 inches.

So, Diagonal is = \sqrt{3} \times7

= 1.732\times7=12.12 inches.

Rounding this to nearest whole number we get 12.

So, the length of the longest metal rod that can be sent is 12 inches.

Joe has two empty boxes, one box is 15 inches wide, 20 inches long and 10 inches high. The second box has the same length and width but is 4 inches taller. How much additional spaces is in the box

Space in the box = volume
volume = length x width x height
box 1 volume = 15 x 20 x 10 = 3000
box 2 volume = 15 x 20 x 14 = 4200
how much space is left = box 2 - box 1 = 1200 inches

When you change fractions and mixed numbers into decimals, why is the denominator always 10, or 100

So when you turn it into a decimal it has a correct place value say if you have 0.70 as a fraction it would be 70/100 because the fraction is telling you it's hundredths one tip is look at the decimal pretend it's always a 1 then in front of the decimal is all zeros and that is your denominator.

The data shows the number of grams of fat found in 9 different health bars. 11, 11.5, 10.5, 17, 14.5, 14.5, 18, 17, 19 What is the IQR (interquartile range) for the data? a. 6.25 b.7 c.14.5 d.17.5

Answer:

Option A. 6.25

Step-by-step explanation:

The data shows the number of grams of fat found in different health bars is

11, 11.5, 10.5, 17, 14.5, 14.5, 18, 17, 19

Now we will arrange the data in ascending order

10.5, 11, 11.5, 14.5, 14.5, 17, 17, 18, 19

Middle of the numbers is 14.5 which is median of the data.

We know IQR = Median of first quartile - median of second quartile

Median of first quartile = \frac{1}{2}(11+11.5)=11.25

And median of second quartile = \frac{1}{2}(17+18)=\frac{35}{2}=17.5

Now IQR = 17.5 - 11.25 = 6.25

Therefore Option A 6.25 is the correct option.
