What is the distance from P to Q?<br> A. 1 unit<br> B. 25 units<br> C. 7 units<br> D. 5 units

sattari [20]

Answer: <em>D. 5 units</em>

Step-by-step explanation:

$d=\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} } \\\\PQ=\sqrt{(3-(-1) )^{2} +(-1-(-4) )^{2} } \\\\PQ=\sqrt{4^{2}+3^{2} } \\\\PQ=\sqrt{16+9} \\\\PQ=\sqrt{25} =5$

A plot of land is 3/8 mile by 2 1/4 miles. Spencer solves 3/8•2 1/4 to find the area of the land in square miles. Enter numbers

Marina CMI [18]

9514 1404 393

Answer:

Step-by-step explanation:

The number 2 1/4 is split into the sum 2 + 1/4, then multiplied by 3/8. This gives ...

$\displaystyle\frac{3}{8}\cdot2\frac{1}{4}=\left(\frac{3}{8}\cdot\boxed{2}\right)+\left(\frac{3}{8}\cdot\frac{1}{4}\right)\\\\=\frac{6}{8}+\frac{3}{\boxed{32}}=\frac{24}{32}+\frac{3}{32}=\frac{24+3}{32}\\\\=\frac{\boxed{27}}{32}$

Of course, fractions are multiplied in the usual way:

$\dfrac{a}{b}\cdot\dfrac{c}{d}=\dfrac{ac}{bd}$

Please Help!! Thanks in advance!

galben [10]

Given:

The equation is:

$\dfrac{y}{p-q}=\dfrac{y}{p+q}$

To find:

The value of y.

Solution:

We have,

$\dfrac{y}{p-q}=\dfrac{y}{p+q}$

On cross multiplication, we get

$y(p+q)=y(p-q)$

$yp+yq=yp-yq$

$yp+yq-yp+yq=0$

$2yq=0$

Dividing both sides by 2q, we get

$\dfrac{2yq}{2q}=\dfrac{0}{2q}$

$y=0$

Therefore, the correct option is A.

In a certain year, exactly 1,481 fewer women than men applied to U.S. medical schools. If 29,250 men applied, what was the total

Oxana [17]

The total number of people who applied to U.S. medical schools this year would be 57,019.

29,250 - 1,481 = 27,769
29,250 + 27,769 = 57,019

If a translation maps ∠I onto ∠K, which of the following statements is true?

jonny [76]

The statement which is true is ΔGHI ~ ΔGJK.

<h3>What is Translation?</h3>

This is commonly used in geometry to describe a function which moves object at distances.

This therefore means that translation of ∠I onto ∠K means shifting of point I to point K.

The triangles given are HGI and JGK.

Translation in this scenario therefore means that the triangles are similar only if other angles are mapped to their corresponding angles.

It confirms that ΔGHI ~ ΔGJK thereby making it the most appropriate choice.
