QUESTION POSTED AT 28/03/2020 - 12:48 PM

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.

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.

There are 10 boys and 13 girls in Ms. Kelso’s homeroom. She is going to select one boy and one girl to act as homeroom representatives for student council. How many different pairs of students could Ms. Kelso choose? A.) 10 B.) 23 C.) 130 D.) 230

The notation for this is {10 \choose 1} \cdot {13 \choose 1}.

Where you should know that {n \choose k} =  \frac{n!}{k!(n-k)!}

When choosing only one boy and one girl, it becomes simple-ish:

\frac{10!}{9!} \cdot \frac{13!}{12!} = 10 \cdot 13 = 130

So I would vote for C, hoping I didn't overlook anything...

Triangle ABD is similar to triangle ACD. AB = 10, BC = 12, BE = 4, and CD = y. Find y.

There is a mistake in your writing
:The similar triangles should be ABE (& not ABD as you stated) & ACD

If so, we can write the following proportion:

AB/AC = BE/CD.
We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22
Plug into the above: 10/22 =4/y===> y= (22 x 4)/10===> y =44/5 =8.8

Joel is laying pipe for a sprinkler system before he plants his lawn. The lawn is a rectangle, 15 feet long and 8 feet wide. He needs to lay a piece of pipe that will run along the diagonal of the lawn. It will divide the area of the lawn into two right triangles. What will be the length of the pipe? A. 120 feet B. 17 feet C. 23 feet D. 289 feet

Answer: B is the right answer. Diameter of the given rectangular lawn=17 feet.


Step-by-step explanation:

Given: A rectangular lawn 15 feet long and 8 feet wide.

To find the diagonal of lawn such that it will divide the area of the lawn into two right triangles. [i.e. diagonal will be the hypotenuse]

So by Pythagoras theorem of right triangles,

hypotenuse^2=perpendicular^2+base^2\\\Rightarrow\ diagonal^2=length^2+width^2\\\text{substitute the values of length and width,we get}\\\Rightarrow\ diagonal^2=15^2+8^2=225+64=289\\\Rightarrow\ diagonal=\sqrt{289}= \sqrt{17\times17}=17

Therefore diameter of the given rectangular lawn=17 feet.
