<h2>Area of Shaded</h2>

Find the area of the shaded area shown.

<h3>Solution:</h3>

  • A = s²
  • A = 32cm
  • A = 32cm x 32cm
  • A = 1024
  • A = 32/4/2
  • A = 32 ÷ 2
  • A = 8
  • A = 8 ÷ 2
  • A = 4

So in the inscribed circle there are 16.

  • A = 16 radius ²
  • A = 16 x 4r²
  • A = 4 x 4
  • A = 16
  • A = 16π x 16
  • A = 256π
  • A = 256 x 3.14
  • A = 803.84
  • A = 1024cm - 803.84
  • A = 220.16cm²

HELP!! 4. (01.02 MC)<br> Which number line shows the solution to -3- (-1)? (1 point)<br> o
statuscvo [17]

Answer:

<em>The third choice gives the correct sequence.</em>

Step-by-step explanation:

<u>The Number Line</u>

To represent numbers in the line, we use arrows starting from the mark for zero up to the given number. If the number is positive, the arrow points to the right and if the number is negative, the arrow points to the left.

The number -3 must be represented as an arrow to the left side of length 3. Subtracting something from the number should also point to the left side, but if the number is negative, then the new arrow points to the right side.

To subtract -1, the arrow should point to the right starting from -3

The third choice gives the correct sequence.

PLEASE HELP ASAP!!!
Dafna1 [17]

Answer:

Step-by-step explanation:

Any time you have compounding more than once a year (which is annually), unless we are talking about compounding continuously, you will use the formula

A(t)=P(1+\frac{r}{n})^{(n)(t)}

Here's what we have:

The amount after a certain time that she has in the bank is 4672.12; that's A(t).

The interest rate in decimal form is .18; that's r.

The number of times the interest compounds is 12; that's n

and the time that the money is invested is 3.5 years; that's t.

Filling all that into the formula:

4672.12=P(1+\frac{.18}{12})^{(12)(3.5)} Simplifying it down a bit:

4672.12=P(1.015)^{42} Raise 1.015 to the 42nd power to get

4672.12 = P(1.868847115) and divide to get P alone:

P = 2500.00

She invested $2500.00 initially.

I don’t know the answer to that one can you help me please
dybincka [34]

Answer:

16/45

Step-by-step explanation:

Step 1:  When dividing fractions, use “KFC”.  It means Keep the first fraction, Flip the second one, and  

              Change it to multiplication

-4/20 ÷ -9/16    →    -4/20 ∙ 16/-9

Step 2:  Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end.  It’s easier arithmetic to reduce at this step.  The first fraction reduces because both the numerator and denominator are divisible by 4.  

-1/5  ∙   16/-9    

Step 3:  Multiply numerators and denominators together to get one fraction

(-16)/(-45)  

Step 4:  Cancel out the negatives, a negative divided by a negative is a positive.  Our final answer is

 

16/45
