5. A cook needs 10 pounds of flour. He wants to spend the least amount of money. A 2-
pound bag costs $1.59 and a 5-pound bag costs $2.89, which should he buy in order to spend
less money? *

Answers

Answer:

He should buy two of the 5-pound bag.

Step-by-step explanation:

The cook needs 10 pounds of flour.

He wants to spend the least amount of money.

First option is a 5-pound bag for $2.89 each.

He can get 2 of the 5-pound bag which equals 10 pounds of flour for 2 x $2.89 = $5.78

Second option is a 2-pound bag for $1.59 each.

He can get 5 of the 2-pound bag which equals 10 pounds of flour for 5 x $1.59 = $7.95.

Second option is $2.17 costlier than the first option.

So, he should go for 2 of the 5-pound bag in order to spend the least amount of money while shopping for 10 pounds of flour.

Alan invests a total of ​$16,500 in three different ways. He invests one part in a mutual fund which in the first year has a return of​ 11%. He invests the second part in a government bond at​ 7% per year. The third part he puts in the bank at​ 5% per year. He invests twice as much in the mutual fund as in the bank. The first year​ Alan's investments bring a total return of ​$1,425. How much did he invest in each​ way?

Answers

Answer:

>> $9000 invested in mutual fund

>> $3000 invested in government bond

>> $4500 put in the bank

Step-by-step explanation:

Let us denote the money invested in each case by a letter. Thus;

a = the money that he invested in a mutual fund

b = the money that he invested in a government bond

c = the money that he put in the bank

We are told that he invested a total of ​$16,500. Thus;

a + b + c = 16500 - - - (eq 1)

He invested twice as much in the mutual fund as he did in the bank. Thus;

a = 2c - - - (eq 2)

From the percentage given and the return of ​$1,425 from the first year investments, we have;

0.11a + 0.07b + 0.05c = 1425 - - - (eq 3)

Let's put 2c for a in eq (1) and eq (3)

Thus;

2c + b + c = 16500

b + 3c = 16500 - - - (eq 4)

Also,

0.11(2c) + 0.07b + 0.05c = 1425

0.07b + 0.27c = 1425 - - - (eq 5)

From eq 4, b = 16500 - 3c

Putting this in eq(5) gives;

0.07(16500 - 3c) + 0.27c = 1425

1155 - 0.21c + 0.27c = 1425

0.06c = 1425 - 1155

0.06c = 270

c = 270/0.06

c = $4500

b = 16500 - 3(4500)

b = 16500 - 13500

b = $3000

Since a = 2c, then;

a = 2(4500)

a = $9000

Answer:

x = 24

Step-by-step explanation:

We can tell by two ways: We already know the value of one of the angles; 66 degrees. We can tell the value of the other one, because it has the right angle symbol, meaning it's 90 degrees. Remember that every triangle's degrees always add up to 180. We can find x by adding 90 and 66 together, which results in 156. Subtract 156 from 180 and you get 24. Therefore, the value of x is 24 degrees.

Answer:

24 degrees

Step-by-step explanation:

The total of a triangle is 180 degrees and a right angle is 90 degrees ( you can tell it's a right angle if it forms the shape of a straight capital "L" or if it has the square in that corner).

So to simplify this , add 90 and 66 which equals 156.

Now we subtract 156 from 180 ---->    180 - 156 = 24

So 24 degrees is your answer.
