1. Almost No Fat Banana Bread Makes 12 servings
You need to serve 48 people for a school event. Adjust the
recipe. Everyone will have 1 piece each.
Final answer:
To serve 48 people with the 'Almost No Fat Banana Bread' when the original recipe serves 12, multiply the quantities of each ingredient in the recipe by 4.
Explanation:
To adjust the recipe for 'Almost No Fat Banana Bread' to serve 48 people, where the original recipe makes 12 servings, you need to multiply the quantities of each ingredient in the recipe by 4. Since you are aiming to serve 1 piece each to 48 people and the original recipe serves 12, the calculation is:
Number of servings needed ÷ Original number of servings per recipe = Multiplier
48 servings needed ÷ 12 servings per recipe = 4
Therefore, you will multiply each ingredient by 4 to make enough banana bread for 48 servings.

In a arithmetic sequence with a^1=12, d=3 which term is equal to 159?
Answer:
50th term is 159
Step-by-step explanation:
nth term=159
a + (n -1)*d = 159
12 + (n-1)*3= 159
(n - 1)*3 = 159 - 12
(n - 1)*3 = 147
n -1 = 147/3
n - 1 = 49
n = 49 + 1
n= 50
Answer: n=50th term
Step-by-step explanation:
An= a1+(n-1)d
An= nth term
A1= first term
N= nth position
D= common difference
An =159
A1= 12
D= 3
N= ?
Substitute the values
An=a1+(n-1)d
159=12+(n-1)3
Collect like terms
159-12=(n-1)3
147=3n-3
147+3=3n
150=3n
N=150/3
N= 50
Therefore 50th term will give 156

A bag contains pennies nickels dimes and quarters. There are 50 coins in all. Of the coins 14 percent are pennies and 42 percent are dimes. There are 4 more nickels than pennies. How much money does the bag contain?
Final answer:
The bag contains 7 pennies, 11 quarters, 21 dimes, and 11 nickels. The value of the bag is $5.47.
Explanation:
Let's denote the number of pennies as P, nickels as N, dimes as D, and quarters as Q.
From the given information, we can form the following equations:
P + N + D + Q = 50 (since there are 50 coins in total).P = 0.14 * 50 = 7 (since 14% of the coins are pennies).D = 0.42 * 50 = 21 (since 42% of the coins are dimes).N = P + 4 (since there are 4 more nickels than pennies).Substituting the values of P and D into the first equation, we can solve for Q:
7 (pennies) + (P + 4) (nickels) + 21 (dimes) + Q (quarters) = 50
11 + 7 + 21 + Q = 50
39 + Q = 50
Q = 50 - 39 = 11
Now, we can calculate the value of the coins:
Value of pennies: 7 * 0.01 = $0.07
Value of nickels: (7 + 4) * 0.05 = $0.55
Value of dimes: 21 * 0.10 = $2.10
Value of quarters: 11 * 0.25 = $2.75
The total value of the coins in the bag is $0.07 + $0.55 + $2.10 + $2.75 = $5.47.

A rectangular parking area measuring 5000 ft squared is to be enclosed on three sides using chain-link fencing that costs $5.50 per foot. The fourth side will be a wooden fence that costs $7 per foot. What dimensions will minimize the total cost to enclose this area, and what is the minimum cost?
Answer:
Dimensions: 75.3778 ft and 66.3325 ft
Minimum price: $1658.31
Step-by-step explanation:
Let's call the length of the parking area 'x', and the width 'y'.
Then, we can write the following equations:
-> Area of the park:
x * y = 5000
-> Price of the fences:
P = 2*x*5.5 + y*5.5 + y*7
P = 11*x + 12.5*y
From the first equation, we have that y = 5000/x
Using this value in the equation for P, we have:
P = 11*x + 12.5*5000/x = 11*x + 62500/x
To find the minimum of this function, we need to take its derivative and then make it equal to zero:
dP/dx = 11 - 62500/x^2 = 0
x^2 = 65000/11
x = 250/sqrt(11) = 75.3778 ft
This is the x value that gives the minimum cost.
Now, finding y and P, we have:
x*y = 5000
y = 5000/75.3778 = 66.3325
P = 11*x + 62500/x = $1658.31
The dimensions that would minimize the total cost are [tex]66.3 \text{ by } 75.4[/tex]
The minimum cost is [tex]\$1658.3[/tex]
Let the sides of the rectangle be [tex]a[/tex] and [tex]b[/tex],
Let the total cost be given by [tex]T=7a+5.5(2b+a)[/tex]
The area, [tex]5000=a\times b \implies a=\frac{5000}{b}[/tex]
Substitute the formula for [tex]a[/tex] into the formula for [tex]T[/tex] to solve for [tex]b[/tex]
[tex]T=\frac{62500}{b}+11b[/tex]
To find the dimensions that would minimize the total cost,
Differentiate to get where the gradients equal zero[tex]\frac{dT}{db}=11-\frac{62500}{b^2}=0[/tex]
when
[tex]b=\pm \frac{250}{\sqrt{11}}[/tex]
Find the second derivative to find the minima[tex]\frac{d^2T}{db^2}=\frac{125000}{b^3}[/tex]
For minima, [tex]\frac{125000}{b^3}>0[/tex]
This means, [tex]b=+\frac{250}{\sqrt{11}}\approx 75.4 ft[/tex] is a minima
The corresponding value of [tex]a=\frac{5000}{b}=\frac{5000}{250}\times\sqrt{11}=20\sqrt{11}\approx 66.3 ft[/tex]
To find the minimum cost, substitute the above minimum value for [tex]b[/tex] into the formula for the total cost
[tex]T=500\sqrt{11}=\$1658.3[/tex]
