What is the unit distance, Rounded to the nearest hundredth, between the points (-5, 2) and (3, 7)?

Lostsunrise [7]

Answer:

Distance=9.43 units

Step-by-step explanation:

When you have two coordinates and you need to find the distance between them, you can use the distance formula.

D=sqrt(7-2)^2+(3-(-5))^2

D=sqrt(5^2+8^2)

D=sqrt(25+64)

D=sqrt89

D=9.43, rounded to the nearest hundredth.

Therefore, your distance would be 9.43 units.

I hope this helped! Have a good rest of your day~

I dont know how to do this pls help

Alecsey [184]

Answer:

1) 225

2) 2304

Step-by-step explanation:

Use geometric mean of legs

$x = \sqrt{(16+9)^2 * 9^2} = \sqrt{25^2 * 9^2} = 25 * 9 = 225$

Use geometric mean of altitude

$x = \sqrt{(100-36)^2 * 36^2} = \sqrt{64^2 * 36^2} = 64 * 36 = 2304$

Candice spent 5 1/4 hours doing her homework. Her brother, Ronald, spent 1/2 that number of hours doing his homework. How many h

Elden [556K]

Let

x-----> the number of hours that Candice spent doing her homework

y-----> the number of hours that Ronald spent doing his homework

we know that

$x=5\frac{1}{4}\ hours$

convert mixed number to an improper fraction

$5\frac{1}{4}\ hours=\frac{5*4+1}{4}= \frac{21}{4}\ hours$

$x=\frac{21}{4}\ hours$ -------> equation A

$y=\frac{1}{2}x$ ------> equation B

Substitute equation A in equation B

$y=\frac{1}{2}*\frac{21}{4}=\frac{21}{8}\ hours$

convert an improper fraction to a mixed number

$\frac{21}{8}\ hours=2.625=2+0.625=2+\frac{5}{8}=2\frac{5}{8}\ hours$

therefore

the answer is the option B

$2\frac{5}{8}\ hours$
