In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:


A = wh + \frac 1 2 \pi (\frac w 2)^2


The halfs are because a semicircle is half a circle and a radius is half a diameter.


We're told


h = 1+ 3w


Substituting,


A(w) = w(1+3w) + \frac 1 2 \pi (\frac w 2)^2


Answer: B

Sarah is making strings of beads in the first string she uses 3 beads and she triples the number of beads in each of the next st
xenn [34]

Answer:

She uses 243 beads for the 5th string.

Step-by-step explanation:

In this problem, we can see a pattern. If she triples the number of beads in each of the next strings, that means that we just take the last number and multiply by 3. If the first string uses 3, then:

The second uses 9, 3 * 3 = 9

The third uses 27, 9 * 3 = 27

The fourth uses 81, 27 * 3 = 81

And the 5th uses 243, 81 * 3 = 243.

12.68 is greater than 12.8 because 68 is better than correct
77julia77 [94]

Answer:That is incorrect. 12.8 is greater than 12.68 because .8 is greater than .68

Step-by-step explanation: Since “68” has been placed after the decimal, it is actually “.68” which is less than 1. From here, you have to figure out if .8 or .68 is closer to the number 1 and since .8 is closer, point 12.8 is greater than 12.68

a. log₈8 = 1

b. log₇6/5

c. log₉3¹

<h3>The solution to the problem are</h3>

1. log₈ 2 * 4 would produce an integer

= log₈8 = 1

The output is an integer

2. log₇6/5 would give us an irrational number

= log₇1.2

This would give us an irrational number

3. log₉3¹ would give us a rational number

= log₉9^^\frac{1}{2} = 1/2 log⁹9

= 1/2
