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.

A contractor is building a fenced-in area at a daycare. The area will be rectangular with the length of its base equal to half t

AlladinOne [14]

Answer:

The length of fencing will be $300\ ft$

Step-by-step explanation:

Step 1

Find the dimensions of the rectangle

we know that

The area of a rectangle is equal to

$A=bh$

In this problem we have

$A=5,000\ ft^{2}$

$5,000=bh$ -----> equation A

$b=\frac{h}{2}$ -----> equation B

Substitute equation B in equation A

$5,000=(\frac{h}{2})h$

$10,000=h^{2}$

square root both sides

$h=100\ ft$

Find the value of b

$b=\frac{h}{2}$ -----> $b=\frac{100}{2}=50\ ft$

step 2

Find the length of fencing

The perimeter of a rectangle is equal to

$P=2(b+h)$

we have

$h=100\ ft$

$b=50\ ft$

substitute

$P=2(50+100)=300\ ft$

Anyone can do this please if you can do all of it of you can I'm really bad at math

Vilka [71]

Im Gonna Do 14 And 15.

14:
3/4 (9/12) + 1/3 (4/12) = 13/12
4/5 (16/20) - 1/4 (5/20) = 11/20

15:
-15 < -6
-31 < -19
-5 < 20
-21 < -15
0 < 22
-57 < -26
-71 < -10
3 < 21
-124 < 30
-43 < 18

Hope This Helps!

Also is this one right ? I am really confused ?!

Ostrovityanka [42]

I think that the right answer is $5 because if he want 4 toppings, that would be 0.75+0.75+0.75+0.75 which is 3 and ten you do 2+3=$5
