Similarity and altitudes in right triangles
Aleks04 [339]

Answer: First I suggest that you write out the all the proportions which govern the 3 right triangles involved.

Once you do that you will find this one:

PQ/PS =PR/PQ

PR=PS+SR

Substitution will give you this quadratic:PQ2=PS2+PS*SR

144=PS2+7PS which has only one solution which make sense, namely 9

Then QS=sqrt(144-81)

Trisha drew a scale drawing of a campground. The scale of drawing was 5 inches = 1 yard. What is the Drawing's scale factor? Sim
kobusy [5.1K]

Answer:

The answer to the question is;

the Drawing's scale factor is 5:36.

Step-by-step explanation:

To solve the question, we note that

1 yard = 3 feet and 1 feet = 12 inches

Therefore 1 yard = 1yard*3\frac{feet}{yard}*12\frac{inches}{feet}  = 36 inches

Therefore Where the scale of the drawing is 5 inches = 1 yard, we have

the scale of the drawing is 5 inches = 36 inches

5 inches is equivalent to 36 inches in real life

That is the scale is 5 is to 36  which is 5:36.

Answer:

0.00851=8.51\times 10^{-3} cm.

Step-by-step explanation:

We have been given that the average human body cell is about 5.1\times10^{-4} cm in diameter. The diameter of a plant cell is 8\times10^{-3} cm.

To find the combined diameter of the body cell and plant cell, we will add both diameters.

First of all let us convert our given diameters in standard notation.

5.1\times10^{-4}=0.00051

8\times10^{-3}=0.008

\text{The combined diameter of body cell and plant cell}=0.00051+0.008

\text{The combined diameter of body cell and plant cell}=0.00851

Let us convert our answer in scientific notation.

\text{The combined diameter of body cell and plant cell}=8.51\times 10^{-3}

Therefore, the combined diameter of the body cell and plant cell is 0.00851=8.51\times 10^{-3} cm.

In the image, point A marks the center of the circle. Which two lengths must form a ratio of 2:1?
aksik [14]
Draw a diameter through the center of the circle.  Any radius of this circle is 1/2 the length of the diameter.  Thus, if we divide the diameter into two equal parts, we have two lengths that form the ratio 2:1, where 2 represents the diameter and 1 the radius.

When using _:_, you are contrasting two things so, you are putting a argument to go against the other side.
Not all birds can fly is going against All birds can fly.
