Answer:

131.88 units

Step-by-step explanation:

Area of the circle = πr^{2} = 1384.74 sq. units

       r^{2} = \frac{1384.74}{3.14} = 441 = 21^{2}

   r  = 21 units

Circumference of circle = 2πr  = 2*3.14*21 = 131.88 units

Answer:

<h2>x =  -  \frac{19}{4}</h2>

Option B is the correct option.

Step-by-step explanation:

-  \frac{1}{2}  + x =  -  \frac{21}{4}

Move constant to R.H.S and change its sign:

x =  -  \frac{21}{4}  +  \frac{1}{2}

Take the L.C.M

x =  \frac{ - 21 + 1  \times 2}{4}

x =  \frac{ - 21 + 2}{4}

Calculate

x =  -  \frac{19}{4}

Hope this helps...

Good luck on your assignment..

Answer:

Hello!

An irrational number is all the real numbers which are not rational numbers.

M = \sqrt{2 is a irrational number.

N = \sqrt{5} is a irrational number.

S = 2 is not irrational, and is actually a whole number.

T = 5 is not irrational, and is actually a whole number.

Have a great day!

Explain in words how to find the product of -4 (-1.5) using a number line.where do you end up
Ierofanga [76]

Answer:

To multiply two minus numbers they  will result as a positive number.

the product of any numbers when there is a negtive will always have 2 negtives invlved form three numbers including the answer.

-4 x -1.5 is the same as 4 x 1.5

the answer is  6

Three numbers like -1 x  4 will also be 2 numbers of negative.

= -4

We change this to -4 x 1.5 and shows the answer as -6

But the question had 2 negative numbers already and the answer is just positive 6.
