<h3>A television with a 5:4 screen shows an image with a ratio of 20:12 which creates a letter boxed image. What percent of the screen's area is occupied by the image?</h3>

Answer: d. 75% of the screen is occupied by the image  

Step-by-step explanation:

First we have to find a relation between image area and screen area.

Image area is the product of image dimensions.

Screen area is the product of screen dimensions.

We have to divide the major image dimension between the major screen dimension

Major image dim/Major screen dim = 20/5 = 4

Now we have to multiply this relation by the minor screen dimension

Minor screen dim x 4 = 4 x 4 = 16

Then we have found 5/4 = 20/16

Now we can calculate what percent of the screen area is occupied by the image area.

Major image dim x minor image dim/Major screen dim x minor screen dim

Since major image dim = major screen dim, we have:

Minor image dim/Minor screen dim = 12/16 = 0.75 = 75% of the screen

Answer: d. 75% of the screen is occupied by the image

In a certain Algebra 2 class of 29 students, 7 of them play basketball and 14 of them
Mariulka [41]

Answer:

<em>Two possible answers below</em>

Step-by-step explanation:

<u>Probability and Sets</u>

We are given two sets: Students that play basketball and students that play baseball.

It's given there are 29 students in certain Algebra 2 class, 10 of which don't play any of the mentioned sports.

This leaves only 29-10=19 players of either baseball, basketball, or both sports. If one student is randomly selected, then the propability that they play basketball or baseball is:

\displaystyle P=\frac{19}{29}

P = 0.66

Note: if we are to calculate the probability to choose one student who plays only one of the sports, then we proceed as follows:

We also know 7 students play basketball and 14 play baseball. Since 14+7 =21, the difference of 21-19=2 students corresponds to those who play both sports.

Thus, there 19-2=17 students who play only one of the sports. The probability is:

\displaystyle P=\frac{17}{29}

P = 0.59

Plz answer this i need help its done today
olga55 [171]

Answer:

1) 1/10

2) 1/2

3) 1/5

Step-by-step explanation:

1)

1 favorable outcome and 10 total outcomes.

P(3) = \frac{1}{10}

2)

5 favorable outcomes and 10 total outcomes

P(even) = \frac{5}{10} = \frac{1}{2}

3)

2 favorable outcomes and 10 total outcomes

P(multiples\ of\ 5) = \frac{2}{10} = \frac{1}{5}

15 - 3k = 10(k-5) <br> Can someone please answer this
solmaris [256]

Answer:

k = 5

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

15 - 3k = 10(k - 5)

<u>Step 2: Solve for </u><em><u>k</u></em>

  1. Distribute 10:                              15 - 3k = 10k - 50
  2. Add 3k to both sides:                15 = 13k - 50
  3. Add 50 to both sides:                65 = 13k
  4. Divide 13 on both sides:            5 = k
  5. Rewrite:                                       k = 5

<u>Step 3: Check</u>

<em>Plug in k into the original equation to verify it's a solution.</em>

  1. Substitute in <em>k</em>:                    15 - 3(5) = 10(5 - 5)
  2. Subtract:                              15 - 3(5) = 10(0)
  3. Multiply:                               15 - 15 = 0
  4. Subtract:                              0 = 0

Here we see that 0 does indeed equal 0.

∴ k = 5 is a solution of the equation.
