For your vegetable garden, you plan to plant 5 12 of it in corn, 1 6 in different kinds of beans, and 1 12 in tomatoes. You will

Ymorist [56]

Answer:

$\frac{2}{9}$ part of the garden will be planted in onions and squash combined.

Step-by-step explanation:

Given:

For your vegetable garden, you plan to plant 5 12 of it in corn, 1 6 in different kinds of beans, and 1 12 in tomatoes.

You will plant the remainder equally in eggplant, onions, and squash.

Now, to find the part of garden that will be planted in onions and squash combined.

Part of garden plan for planting corn = $\frac{5}{12}$

Part of garden plan for planting kinds of bean = $\frac{1}{6}$

Part of garden plan for planting tomatoes = $\frac{1}{12}$

So, adding all the parts of corn, beans and tomatoes:

$\frac{5}{12}+\frac{1}{6} +\frac{1}{12} \\\\=\frac{5+2+1}{12} \\\\=\frac{8}{12}$

Now, to get the rest of the parts of garden use to plant eggplant, onions, and squash we subtract $\frac{8}{12}$ from 1 whole:

$1-\frac{8}{12} \\\\=\frac{12-8}{12} \\\\=\frac{4}{12}$

As, given planting the remainder equally in eggplant, onions, and squash.

So, each will be planted in part of:

$\frac{4}{12} \div 3$

$=\frac{4}{12}\times \frac{1}{3}$

$=\frac{4}{36}$

On simplifying it:

$=\frac{1}{9}$ .

Thus, $\frac{1}{9}$ part of the garden for each eggplant, onions, and squash.

Now, to get the part of the garden will be planted in onions and squash combined we add $\frac{1}{9}$ part of garden planting for onions and $\frac{1}{9}$ of squash:

$\frac{1}{9} +\frac{1}{9} \\\\=\frac{1+1}{9} \\\\=\frac{2}{9}$

Therefore, $\frac{2}{9}$ part of the garden will be planted in onions and squash combined.

NEED HELP ASAP i need to simplify (f+g)(x) if f(x) = x+4 and g(x) = 3x^2-8

kogti [31]

We can also think of this problem as f(x) + g(x). Therefore, all we need to do is add the two functions together.

x + 4 + 3x^2 - 8 || Write it out!

3x^2 + x + 4 - 8 || Rearrange in order of decreasing exponents. No need to combine and rearrange all at once!

3x^2 + x - 4 || Combine like terms!

Hope this helps!! :)

So you want to finance a car for $4840 let's say we offer a 4.5% interest rate on a two year loan at 6% on a five year loan?

Virty [35]

Answer:

Interest Rate on 2-Year Loan...$435.6

Interest Rate on 5-Year Loan...$1,452

Step-by-step explanation:

The formula for calculating simple interest is as follows.

I = P x R x T,

where I = interest

P= Principal

R= interest rate

T= time

For the loan at 4.5 percent for 2 years, the interest will be

= $4,840 x 4.5/100 x 2

= $4,840 x 0.045 x 2

= $435.6

Total cost of the loan will principal plus interest

=$435.6 + $4,840

=$5,275.6

Monthly loan cost

= $5,275.6/24

=$219.81

Total loan cost..$5,275.6

Monthly loan cost ...$219.81

For the Loan at 6 percent for 5 years, the interest will be

= $4,840 x 6/100 x 5

= $4,840 x 0.06 x 5

=$1,452

Total cost of the loan will be principal plus interest

=$ 4,840 + $1,45

=$6,292

Monthly costs will be

=$6,292/60

=$104.87

Total loan cost... $6,292

Monthly loan costs... $104.87

Pete's Convenience Store has a beginning inventory of 12 cans of soup at a cost of $.85 each. During the year, the store purchas

Zepler [3.9K]

A) The number of cans of soup in ending inventory is <u>19.</u>

B) The cost of the ending inventory under LIFO, FIFO, and the weighted average is as follows:

LIFO $17.15

FIFO $25.65

Weighted average $21.47

<h3>What are the inventory methods?</h3>

The inventory methods include First-in, First-out (FIFO), Last-in, First-out (LIFO), Weighted Average, and Specific Identification.

FIFO assumes that the physical flow of goods during sales follows the chronological sequence of their acquisition.

LIFO assumes that the first goods acquired are the last to be sold.

The Weighted Average uses an average to determine the costs allocated to ending inventory and the cost of goods sold.

Specific Identification identifies the specific goods sold with their costs.

Description Units Unit Cost Total

Beginning inventory 12 $0.85 $10.20

Purchases 4 $0.95 $3.80

Purchases 6 $1.05 $6.30

Purchases 7 $1.35 $9.45

Purchases 8 $1.50 $12.00

Total 37 $41.75

Sales 18

Ending inventory 19 (37 - 18)

Average cost = $1.13 ($41.75/37)

<u>LIFO</u>:

Ending inventory = $17.15 ($10.20 + $3.80 + 3 x $1.05)

<u>FIFO</u>:

Ending inventory = $25.65 (4 x $1.05 + $9.45 + $12.00)

<u>Weighted Average</u>

Ending inventory = $21.47 (19 x $1.13)
