A school group is helping plant a new city garden. Today they used 12 1/2 pounds of potting soil and planted 2/5 of the garden.

Len [333]

Answer:

$18\frac{3}{4}$ pounds.

Step-by-step explanation:

Let x be the total amount of potting soil needed to complete the planting in new garden.

We are told that a school group is helping plant a new city garden. Today they used 12 1/2 pounds of potting soil and planted 2/5 of the garden. This means 2/5 of x equals to 12 1/2.

$\frac{2}{5} x=12\frac{1}{2}$

$\frac{2}{5} x=\frac{25}{2}$

$x=\frac{25}{2}\times\frac{5}{2}$

$x=\frac{125}{4}$

To find the amount of soil needed for the next of planting we will subtract the amount of potting soil used on the first day $(\frac{25}{2})$ from amount of total potting soil $(\frac{125}{4})$ .

$\text{Amount of potting soil needed for second day}=\frac{125}{4}-\frac{25}{2}$

$\text{Amount of potting soil needed for second day}=\frac{125}{4}-\frac{25\times 2}{2\times2}$

$\text{Amount of potting soil needed for second day}=\frac{125}{4}-\frac{50}{4}$

$\text{Amount of potting soil needed for second day}=\frac{75}{4}$

$\text{Amount of potting soil needed for second day}=\frac{75}{4}=18\frac{3}{4}$

Therefore, the group will need $18\frac{3}{4}$ pounds of potting soil to finish their work.

The diagonals of rhombus ABCD intersect at E. Given that m∠CAD=20° and CE=4, find the m∠CDA.

V125BC [204]

Answer:

<em>< CDA = 140 degrees </em>

Step-by-step explanation:

For a rhombus, the sum of the interior angles is 360 degrees and also the opposite angles are equal i.e <ABC = <CDA and <BAD = <BCD

Given

<CAD = 20 degrees

<BCE = 20 degrees (based on geometry)

<BAD = <CAD + <BCE

<BAD = 20 + 20

<BAD = 40 degrees

Since <BAD = <BCD, then <BCD = 40 degrees

Get <CDA

<CDA + <ABC + <BAD + <BCD = 360

<CDA + <CDA + <BAD + <BCD = 360

2 < CDA + 40 + 40 = 360

2< CDA + 80 = 360

2< CDA = 360-80

2< CDA = 280

< CDA = 280/2

<em>< CDA = 140 degrees </em>

Subtract 7x + 4y − 2z from 4x + 2y.

sukhopar [10]

Answer:

-3x-6y-2z

Step-by-step explanation:

(4x - 2y)-(7x+4y-2z) = 4x-2y-7x-4y-2z = -3x-6y-2z

I hope that's the answer.
