Answer:

It's app. 50.24

Step-by-step explanation:

The area of a circle is A = pi * r ^2

So the area is

= pi * 16

in the question it says to use 3.14 for pi instead

so multiply 16 * 3.14 = 50.24

Answer:

50.24 square miles

Step-by-step explanation:

The formula for the area of a circle is A=\pi r^{2}

Plug in 3.14 for pi and 4 for r

when you square the 4, you get 16

16 x 3.14 is 50.24

Find the value of x in the triangle shown below​
CaHeK987 [17]

Answer:

<h2>46.4°</h2>

Step-by-step explanation:

Apply sine formula:

\frac{sin \: a}{a}  =  \frac{sin \: b}{b}  =  \frac{sin \: c}{c}

\frac{sin \: a}{a}  =  \frac{sin \: c}{c}

Plug the values

\frac{sin \: (88)}{6.9}  =  \frac{sin \: x}{5}

Apply cross product property

5 \: sin \: (88) = 6.9 \: (sin \: x)

\frac{5 \: sin \: (88)}{6.9}  = sin \: x

x =  {sin}^{ - 1} ( \frac{5 \: sin \:( 88)}{6.9} )

x = 46.4

Hope this helps .....

Best regards!!!

Answer:

x + 5

Step-by-step explanation:

  • 4x + 8 + (-3)(x) + (-3)(1)
  • 4x + 8 -3x -3
  • (4x-3x) + (8-3)
  • x + 5

Therefore, the answer is x + 5.

7 times as much as sum of 1/3 and 4/5
Salsk061 [2.6K]
So the formula is
7*(1/3+1/5) = x

First find the common denominator of the fractions.  In this case the common denominator of 3 and 5 is 15 so we must convert them to 15ths.  To do that we divide 15 by the denominator and take that answer and multiply the numerator by it.

So for 1/3 we take 15/3(denominator) = 5 and multiply the numerator (1) by it

5 * 1 = 5 so 1/3 converts to 5/15

Do the same for 1/5 we take 15/5 = 3 and multiply the numerator (4) by it

3*4 = 12 so 4/5 converts to 12/15

Now we add 5/15 and 12/15 = 17/15 so we have our formula now to

7*17/15

We make seven a fraction 7/1 and multiply across 7*17 = 119 and 15 * 1 = 15

We have 119/15 which when we divide and get 7 14/15 as your answer

I think it's going to make a W, but I don't understand question 3. Can someone please explain this to me?
RideAnS [48]
I thought this was a vector problem but no, this is quite easy!

You are correct; this draws the letter W.

The so-called "vector" means for you to translate the same distance. That vector goes left 3 and up 4 -- translate your point at Step 2 left 3 units and up 4 units. There you go!
