2. You want to buy some beans. A
Ber [7]

Answer:

Step-by-step explanation:

Remark

If you find out the cost of 1 oz of each of them, that will determine the best buy. The smallest number is the best buy.

Givens

7 oz cost $2.38

15 oz cost $5.25

26 oz cost $8.58

Solution

<h3>7 oz</h3>

7 oz cost $2.38

1 oz cost  x                  This is a proportion. 3 quatities are known. Find x Cross multiply.

7/1 = 2.38/x

7x = 2.38

x = $0.34 dollars

<h3>15 oz</h3>

15 oz cost 5.25

1 oz costs x

15.1/1 = 5,25 x              Cross Multiply

15x = 5.25 * 1               Divide by 15                                

x = 5.25 / 15

x = $0.35

<h3>26 oz</h3>

26 oz cost 8.58

1 oz   cost x

26/1 = 8.38/x                 Cross Multiply

26x  = 8.38                    Divide by 26

x = 8.38/20

x = 0.32 dollars

Answer

7 oz cost  0.34

15 oz cost 0.35

26 oz cost 0.32

<h3>The best buy is 0.32 / oz for 26 oz</h3>

Find the fifth term of the arithmetic sequence in which t1 = 3 and tn = tn-1 + 4. A) 5 B) 7 C) 19 D) 23 2) Find the tenth term o
Sergeu [11.5K]
We know that

Part a) <span>Find the fifth term of the arithmetic sequence in which t1 = 3 and tn = tn-1 + 4
t1=3
t2=t1+4----> 3+4-----> 7
t3=t2+4-----> 7+4----> 11
t4=t3+4-----> 11+4---> 15
t5=t4+4-----> 15+4---> 19

the answer Part a) is 19

Part b) </span><span>Find the tenth term of the arithmetic sequence in which t1 = 2 and t4 = -10

we know that 
tn=t1+(n-1)*d-----> d=[tn-t1]/(n-1)
t1=2
t4=-10
n=4
find the value of d
d=[-10-2]/(4-1)-----> d=-12/3----> d=-4
find the </span>tenth term (t10)
t10=t1+(10-1)*(-4)----> t10=2+9*(-4)----> t10=-34

the answer Part b) is -34

Part c) <span>Find the fifth term of the geometric sequence in which t1 = 3 and tn = 2tn-1
t1=3
t2=2*t1----> 2*3----> 6
t3=2*t2----> 2*6----> 12
t4=2*t3-----> 2*12---> 24
t2=2*t4----> 2*24----> 48

the answer Part c) is 48</span>
