Answer:

Step-by-step explanation:

The area A of a circle of radius r is A = πr², where π is often approximated by 3.14.

Here, with the circle diameter being 8, we figure the radius to be half that, or 4.

Then the area of this circle is A = (3.14)(4 in)², or

                                                 A  =  50.24 in²

Answer:

50.24

Step-by-step explanation:

Area = pi*r^2

r = diameter/2

r = 4

Area = pi*4^2

Area = 3.14*16

Area = 50.24

PLEASEE HELPP....Simplify the expression using properties of exponents.​
Aleks04 [339]

Answer:

D

Step-by-step explanation:

Using the rule of exponents

\frac{a^{n} }{a^{m} } = \frac{1}{a^{(m-n)} }

Given

\frac{25a^{-5}b^{-8}  }{5a^{4}b }

= \frac{25}{5} × \frac{a^{-5} }{a^{4} } × \frac{b^{-8} }{b^{1} }

= 5 × \frac{1}{a^{(4-(-5))} } × \frac{1}{b^{(1-(-8))} }

= 5 × \frac{1}{a^{9} } × \frac{1}{b^{9} }

= \frac{5}{a^{9}b^{9}  } → D

Solve for b: 16b = 12
Zina [86]

Answer:

b = 3/4

Step-by-step explanation:

Hi!!!

You want the value of B. To get that, we have to divide both sides by 16:

\frac{16}{16}b =\frac{12}{16}

\frac{12}{16} = \frac{3}{4}

Thus the answer to your question is $\boxed{b = \frac{3}{4} }.

<u>Check:</u>

3/4 * 16 = 3 * 4 = 12.

12 = 12

So we are correct!!!

In a multiple choice quiz there are 5 questions and 4 choices for each question (a, b, c, d). Robin has not studied for the quiz
Mekhanik [1.2K]

Answer:

We have 20 category Questions split into 5

Where we would assume that the 3rd question is simply 1/4 + 5/20 chance.

This is not a determiner as Robin is asked more questions.

So it is simply 1/4 and kept to factors that Robin will answer one of the 4 choices upon the 3rd question as 1/4 regardless of other questions being asked. Where Robins first answer would be the third question we subtract 4/5 = 16/20 - 5/20= 11/40. Which can only be rounded down to 2 decimal places 0.275
