Answer: D = 40 / C

Step-by-step explanation:

total amount of soil divided by soil in each bag. To find the total amount of soil multiply number of flower boxes (10) by amount of soil each box holds (4 kilograms). So, number of bags (D) equals 40 divided by kg of soil in each bag (C)

I have completed the first three parts of this question, but now need help to finish...I need to calculate the ratios of the 4 l

galben [10]

At first, we will find the lengths of LK, Lm, ON, OP, then use them to find the ratios between them

The rule of the distance is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

For LK

Since L = (3, 6), K = (1,5.33), then

$\begin{gathered} LK=\sqrt{(3-1)^2+(6-5.33)^2} \\ LK=\sqrt{4+0.4489} \\ LK=\sqrt{4.4489} \end{gathered}$

For LM

Since L = (3, 6), M = (5, 6.67), then

$\begin{gathered} LM=\sqrt{(3-5)^2+(6-6.67)^2} \\ LM=\sqrt{4+0.4489} \\ LM=\sqrt{4.4489} \end{gathered}$

For ON

Since O = (3, 2.59) and N = (5, 4.2), then

$\begin{gathered} ON=\sqrt{(3-5)^2+(2.59-4.2)} \\ ON=\sqrt{4+2.5921} \\ ON=\sqrt{6.5921} \end{gathered}$

For OP

Since O = (3, 2.59), P = (1, 0.99), then

$\begin{gathered} OP=\sqrt{(3-1)^2+(2.59-0.99)^2} \\ OP=\sqrt{4+2.56} \\ OP=\sqrt{6.56} \end{gathered}$

Now let us find the ratios between them

$\begin{gathered} \frac{KL}{LM}=\frac{\sqrt{4.4489}}{\sqrt{4.4489}}=1 \\ \frac{PO}{ON}=\frac{\sqrt{6.56}}{\sqrt{6.5921}}=0.9975\approx1 \\ \frac{KL}{LM}=\frac{PO}{ON}=1 \end{gathered}$

That means, Parallel lines intercept equal parts

By joining MP

We will have Triangle KPM

Since KL = LM ------- Proved using the distance formula

Since LQ // KP ------ Given

Then MQ = QP ------- Using the theorem down

The theorem

If a line is drawn from a midpoint of one side of a triangle parallel to the opposite side, then it will intersect the 3rd side in its midpoint (Q is the midpoint of MP)

Parallel lines intercept equal parts

EFGH is a rhombus. Given EG = 16 and FH = 12, what is the length of one side of the rhombus?

Tom [10]

Answer

= 10

Explanation

EG is one of the diagonals of the rhombus and the other diagonal is FH.

EG = 16 and FH = 12

The diagonals of a rhombus meet at 90°

From this information we can form a right triangle with legs (16/2)=8 and (12/2)=6

The hypotenuse of this triangle is the side of the rhombus.

Using the pythagorean theorem;

L² = 6²+8²

Where L is the length of the rhombus.

L² = 6²+8²

L = √36+64

= √100

= 10

A Jar contains n nickels and d dimes. There are 22 coins in the jar, and the total value of the coins is $1.55.

kotegsom [21]

They is 9dime and 13 Nickels because 13 x5=65 and 9 x10=90 .So 0.65+ 0.90= 1.55.
