Answer:

9 bags of candy

Step-by-step explanation:

6 cookies at 14 grams each = 84 grams meaning the remaining grams of the 140 have to be the weight of the candy which = 56 grams (140-84). To find out how much candy is in one cookie divide 56 by 6 which = 9.33333. You then divide 20 by 9.3333 which = 2.14 (rounded to nearest 10th). Since you can get just over 2 cookies worth of candy per bag you only need half the number of cookies in bags of candy (9 bags)

Delaney would like to make a 5 lb nut mixture that is 60% peanuts and 40% almonds. She has several pounds of peanuts and several

Alchen [17]

Answer:

a) The system that models the situation is:

p + 0.2m = 3

p + m = 5

b) The solution of the system is:

m = 2.5

p = 2.5

Step-by-step explanat:

It is desired to obtain 5 pounds of a mixture containing 40% peanuts and 60% almonds.

It has a mixture of 20% peanuts and 80% almonds.

p: number of pounds of peanuts

m = amount of mixture

The equation that represents the amount of peanut and mixture that is needed is:

p + m = 5 pounds

m = 5-p (i)

The amount of peanut in total that the mixture should have is:

p + 0.2m = 0.6 (5)

p + 0.2m = 3 (ii)

a) The system that models the situation is:

p + 0.2m = 3

p + m = 5

Now we substitute (i) in (ii) and clear p.

p + 0.2 (5-p) = 3

p-0.2p = 2

p = 2.5 pounds

Now we find m

m = 5 - 2.5

m = 2.5 pounds

b) The solution of the system is:

m = 2.5

p = 2.5

Find a8 when a1= 9, d = 4 of the arithmetic sequence whose first term is a1 and common difference is d.

Gelneren [198K]

General Arithmetic Terms

$\displaystyle \large{a_n = a_1 + (n - 1)d}$

We want to find a8; we know:

a1 = 9
d = 4

Substitute in the formula.

$\displaystyle \large{a_n = 9 + (n - 1)4} \\ \displaystyle \large{a_n = 9 + 4n - 4} \\ \displaystyle \large{a_n = 4n + 5}$

To find a8, substitute n = 8

$\displaystyle \large{a_8= 4(8) + 5} \\ \displaystyle \large{a_8= 32 + 5} \\ \displaystyle \large{a_8= 37}$

Hence, the 8th term of sequence is 37
