18 - Paul: 8 candies
Kid #1: 5 candies
Kid #2: 5 candies
Kid #3: 5 candies

8+5+5+5
8+10+5
8+15
23

Paul had 23 pieces of candy to start with

20 - ?/(1/2) + $6 = $14

?/(1/2) + $6 = $14
$14 - $6 = $8
$8 x 2 = $16
$16/(1/2) + $6 = $14

Jill's weekly allowance is $16.00

Your answer is: Paul-23 candies ; Jill- $16.00

Have an amazing day!

N is the sum of three consecutive primes and is also the product of two 2-digit primes, what is the least possible value of N

Nookie1986 [14]

Hello from MrBillDoesMath!

Answer: N = 143

Discussion:

This one took some trial and error! At first I listed all 2 digit primes, looked at the list, but didn't know how to proceed. So, I took the smallest 2 digit primes numbers: 11 and 13 and wondered if their product, 13*11 = 143, could be represented as the sum of 3 consecutive primes. I went back to my list of primes, added groups of three consecutive numbers that seemed to be in the right range to give the desired sum, and stumbled on 43, 47, and 53!

43 + 47 + 53 = 143 !

Therefore N = 143. It's the sum of 43, 47, and 53 as well as the product of 11 and 13.

Thank you,

MrB

Find a formula for the described function. A rectangle has perimeter 16 m. Express the area A of the rectangle as a function of

Alex17521 [72]

Part A:

Let the length of one of the sides of the rectangle be L, then the length of the other side is obtained as follow.

Let the length of the other side be x, then

$2(L+x)=16 \\ \\ \Rightarrow L+x=8 \\ \\ \Rightarrow x=8-L$

Thus, if the length of one of the side is x, the length of the other side is 8 - L.

Hence, the area of the rectangle in terms of L is given by

$L(8 - L) = 8L-L^2$

Part B:

To find the domain of A

Recall that the domain of a function is the set of values which can be assumed by the independent variable. In this case, the domain is the set of values that L can take.

Notice that the length of a side of a rectangle cannot be negative or 0, thus L cannot be 8 as 8 - 8 = 0 or any number greater than 8.

Hence the domain of the area are the set of values between 0 and 8 not inclusive.

Therefore,

$dom(Area)=0\ \textless \ L\ \textless \ 8 \ or \ (0, 8)$

Answer:

The slope of the line 3.

Step-by-step explanation:

The line is going through 3. Although it is not -3, because if the line is sloping upward from left to right, then the slope is positive (+). If the line is sloping downward from left to right, the slope is negative (-).
