What is the average of the sixth even number, fifth and eighth odd number after 200?

ohaa [14]

<em>Answer:</em>

<em>212 is the answer !</em>

<em>Step-by-step explanation:</em>

<em>Firstly, We'll have to write all the numbers till 220 after 200 that is :</em>

<em>201 , 202 , 203 , 204 , 205 , 206 , 207 , 208 , 209 , 210 , 211 ,212 , 213 , 214 , 215 , 216 , 217 , 218 , 219 , 220 . </em>

<em />

<em>Here we now know the the 6th even number is</em><em> 212.</em>

<em>And the 5th odd number is </em><em>209.</em>

<em>And the 8th odd number is</em><em> 215.</em>

<em />

<em>By using the formula we can find the average that is :</em>

<em>212+209+215/3 </em><em>= 636/3 = 212 </em>

<em />

<em>∴ Your answer is 212 !</em>

If c is the hypotenuse of a right triangle, find the missing side. if necessary, round to the nearest hundredth a=6 b=3 c= ?

nexus9112 [7]

Answer: 6.71

Step-by-step explanation: Using the Pythagorean Theorem, we know that a^2 + b^2 = c^2. Substitute a and b with 6 and 3 respectively and we get 6^2 + 3^2 = c^2. Then 36 + 9 = c^2. Next, 45 = c^2, so we take the square root of 45 and round it to the nearest hundredth, giving the answer of 6.71.

Three friends all have ages that are consecutive integers. The sum of their ages is 180. What is the age of the oldest friend?

Lynna [10]

Answer:

Step-by-step explanation:

Oldest friend=X+2; Middle friend=X+1; Youngest friend=X

X+(X+1)+(X+2)=180

3X+3=180 Subtract 3 from each side.

3X=177 Divide each side by 3

X=59 Youngest friend is 59.

X+2=59+2=61 ANSWER: Oldest friend is 61.

X+2=59+1=60 Middle friend is 60.

CHECK:

Sum is 180

59+60+61=180

180=180

Let f(x) = 2x − 6. solve f−1(x) when x = 2. select one: a. −5 b. 4 c. −2 d. 7

Dvinal [7]

F(x) = 2x - 6

y = 2x - 6
2x - 6 = y |add 6 to both sides
2x = y + 6 |divide both sides by 2
x = 1/2y + 3

f^{-1}(x) = 1/2x + 3

f^{-1}(2) = 1/2 · 2 + 3 = 1 + 3 = 4

Answer: b. 4
