Answer: The spelling questions are 10, while the vocab questions are 16.

Step-by-step explanation: Let the spelling questions be represented by letter p, while the vocab questions should be represented by v. If there is a total of 16 questions as stated, then p + v = 26

Also if there are a total of 100 points obtainable in the test, then spelling questions times 2 points (2p) plus vocab questions times 5 points (5v) equals 100 points. This can be expressed as 2p + 5v = 100

We now have a pair of simultaneous equations as follows

p + v = 26 ———(1)

2p + 5v = 100 ———(2)

Make p the subject of the equation in equation (1). p = 26 - v. Next substitute for the value of p into equation (2)

2(26 - v) + 5v = 100

52 - 2v + 5v = 100

We collect like terms and we have

5v - 2v = 100 - 52

3v = 48

Divide both sides of the equation by 3

v = 16

Now having calculated v, substitute for the value of v into equation (1)

p + 16 = 26

Subtract 16 from both sides of the equation

p = 10

Therefore, the spelling questions equals 10 in all. While the vocab questions equals 16 in all.

A language arts test is worth 100 points. There are a total of 26 questions. There are spelling word questions that are worth 2 points each and vocabulary word questions worth 5 points each. How many of each type of question is there?

Let

x = the number of 2 points questions

y = the number of 5 points questions

x + y = 26

2x + 5y = 100

........

 

x = 10 two points questions

y = 16 five points questions

There are 10 two points and 16 five points questions.

The equation of a function<br>y = 2/3x+1/3 find the value of y<br>when x = -3<br>when x = 1 1/2​
kirill [66]

Answer:

y = \frac{-5}{3}\\\\y = \frac {4}{3}

Step-by-step explanation:

y = \frac{2}{3} x + \frac{1}{3}\\\\when \ x = -3 \\\\y = \frac{2}{3}(-3) + \frac{1}{3} = -2 + \frac{1}{3} = \frac{-6 + 1}{3}= \frac{-5}{3} \\\\When \ x = 1 \frac{1}{2} = \frac{3}{2}\\\\y = \frac{2}{3} \times \frac{3}{2} + \frac{1}{3} = 1+ \frac{1}{3} = \frac{3 + 1}{3}= \frac{4}{3} \\\\

2. Find the area of the regular polygon.
frozen [14]

Answer:

a. 80 units

b. 482.843 units²

Step-by-step explanation:

<em>First</em><em> </em><em>things</em><em> </em><em>first</em><em>,</em><em> </em><em>we</em><em> </em><em>need</em><em> </em><em>to</em><em> </em><em>solve</em><em> </em><em>for</em><em> </em><em>the</em><em> </em><em>side</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>octagon</em><em>. </em><em>We</em><em> </em><em>can</em><em> </em><em>do</em><em> </em><em>so</em><em> </em><em>by</em><em> </em><em>using</em><em> </em><em><u>Pythagorean</u></em><em><u> </u></em><em><u>Theorem</u></em><em><u>:</u></em><em> </em><em>a</em><em>²</em><em> </em><em>+</em><em> </em><em>b</em><em>²</em><em> </em><em>=</em><em> </em><em>c</em><em>²</em><em> </em><em>where</em><em> </em><em>c</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em><u>hypotenuse</u></em><em> </em><em>and</em><em> </em><em>a</em><em> </em><em>and</em><em> </em><em>b</em><em> </em><em>are</em><em> </em><em>the</em><em> </em><em>other</em><em> </em><em>two</em><em> </em><em>sides</em><em>. </em>

12² + b² = 13²

144 + b² = 169

b² = 25

b = 5

<em>Now</em><em> </em><em>that</em><em> </em><em>we</em><em> </em><em>know</em><em> </em><em>half</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>side</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>octagon</em><em> </em><em>is</em><em> </em><em>5</em><em>,</em><em> </em><em>we</em><em> </em><em>know</em><em> </em><em>that</em><em> </em><em>one</em><em> </em><em>side</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>octagon</em><em> </em><em>is</em><em> </em><em>1</em><em>0</em><em>.</em><em> </em>

<em>a</em><em>.</em><em> </em><em>To</em><em> </em><em>find</em><em> </em><em>perimeter</em><em> </em><em>we</em><em> </em><em>just</em><em> </em><em>add</em><em> </em><em>every</em><em> </em><em>side</em><em> </em><em>together</em><em> </em><em>(</em><em>or</em><em> </em><em>since</em><em> </em><em>every</em><em> </em><em>side</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>size</em><em>,</em><em> </em><em>we</em><em> </em><em>multiply</em><em> </em><em>by</em><em> </em><em>8</em><em>)</em>

10 × 8 = 80

<em>b</em><em>.</em> <em>The</em><em> </em><em>formula</em><em> </em><em>for</em><em> </em><em>finding</em><em> </em><em>the</em><em> </em><em>area</em><em> </em><em>of</em><em> </em><em>an</em><em> </em><em>octagon</em><em> </em><em>is</em><em> </em><em>2</em><em>(</em><em>1</em><em> </em><em>+</em><em> </em><em>radical</em><em> </em><em>2</em><em>)</em><em>a</em><em>²</em><em> </em><em>where</em><em> </em><em>a</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>length</em><em> </em><em>of</em><em> </em><em>a</em><em> </em><em>side</em><em>.</em><em> </em><em>By</em><em> </em><em>plugging</em><em> </em><em>in</em><em> </em><em>to</em><em> </em><em>a</em><em> </em><em>calculator</em><em> </em><em>we</em><em> </em><em>get</em><em>:</em>

2(1 + radical 2)(10)² = 482.843
