Answer

102

Step-by-step explanation:

X means 3 not times, lots of people mess that up sometimes. Anyways, do 8+3 which equals 11. 8+3=11. So next what you do is you do 11 + 16 which is 27,

equations:

8+3=11

11+16=27

21/1=27

27/4= 6.75

6 x 3= 27

27 + 72 + 3= 102

Then go back to the beginning and do 1/4. If this confuses let me fix it.

now divide it with 4. Look at the equations list. Okay now do 6.72/4x. MAKE SURE TO MULTIPLY DON'T DIVIDE! You multiply 6 and 4 then you add 72 and three! Then you should end up with 102! I hope this worked message me back if it did :)

What is the Side length

ddd [48]

The formula of a diameter d of a square with side a:

$d=a\sqrt2$

Substitute $d=\sqrt6\ mm$ :

$a\sqrt2=\sqrt6$ multiply both sides by $\sqrt2$

$2a=\sqrt{12}$ used $\sqrt{a}\cdot\sqrt{a}=a$ and $\sqrt{a\cdot b}=\sqrt{a}\cdot\sqrt{b}$

$2a=\sqrt{4\cdot3}$ use $\sqrt{a\cdot b}=\sqrt{a}\cdot\sqrt{b}$

$2a=\sqrt4\cdot\sqrt3$

$2a=2\sqrt3$ divide both sides by 2

$a=\sqrt3\ mm$

The perimeter: $P=4a$

Substitute:

$P=4\sqrt3\ mm$

<h3>Answer: D.</h3>

Other method.

Use the Pythagorean theorem:

$a^2+a^2=(\sqrt6)^2$ use $(\sqrt{a})^2=a$

$2a^2=6$ divide both sides by 2

$a^2=3\to a=\sqrt3\ mm$

$P=4a\to P=4\sqrt3\ mm$

Answer:

a) W(x) = 2, 000 - 275 x represents the given situation.

b) The cost of the computer after 6 years is $350.

Step-by-step explanation:

Initial worth of the company = $2,000

Depreciation each year = $275

Let, W(x) represent the worth of the computer in x - th year.

So, according to the question:

a) W(x) = 2, 000 - 275 x represents the given situation.

b) Solving W(x) for x = 6, we get

W(6) = 2,000 - 275(6) = 2, 000 - 1,650

= 350

⇒W(6) = $350

Hence, the cost of the computer after 6 years is $350.

I think of a number i multiple it by 5 i then subtract 19 finally i double the result the final number is 22 what number did i t

Delicious77 [7]

To solve this problem, you read the problem backwards and to the opposite of that function.

if it says double --> divide by 2 22 / 2 = 11
subtract by 19 --> add 19 11 + 19 =30
multiply by 5 --> divide 5 30 / 5 = 6

Thus the number that is thought of is 6

Hope that helps!
