the human heart pumps 750 gallons of blood in 9 hours. A human kidney filters 100 gallons of blood in 6 hours. How many more gal

lons of blood does the human heart pump than a human kidney filters during a 24 hour period?

The heart pumps 750*24/9=2000 gallons, and the kidney pumps 100*24/6=400 gallons. This is a difference of 2000-400=1600 gallons.

Suppose that NOP is isosceles with base.

NemiM [27]

Step-by-step explanation:

<u>In isocseles triangle, base angles </u><u>are</u><u> equal</u> :

base angles are angle N and angle P:

angle N=angle P

3x+17=4x+2

4x-3x=17-2

x=15

<u>F</u><u>o</u><u>r</u><u> </u><u>a</u><u>n</u><u>g</u><u>l</u><u>e</u><u> </u><u>N</u><u>:</u>

subtitute x in angle N

=3(15)+17

=45+17

=62

<u>F</u><u>o</u><u>r</u><u> </u><u>a</u><u>n</u><u>g</u><u>l</u><u>e</u><u> </u><u>P</u><u>:</u>

subtitute x in angle P:

=4(15)+2

=60+2

=62

<u>F</u><u>o</u><u>r</u><u> </u><u>a</u><u>n</u><u>g</u><u>l</u><u>e</u><u> </u><u>O</u><u>:</u>

sum of all angles in a triangle is 180.

angle N +angle P+angle O=180

62+62+angle O=180

angle O=180-62-62

angle O=56

State the the roots of y=x^2+8x

Likurg_2 [28]

Answer:

The roots of the given equation are x = 0 and x = -8.

General Formulas and Concepts:

<u>Algebra I</u>

Terms/Coefficients

Factoring/Expanding

Quadratic Equations

Solving quadratic equations

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify.</em>

y = x² + 8x

<u>Step 2: Find Roots</u>

[Quadratic] Factor: y = x(x + 8)
[Quadratic] Set up [Solve]: 0 = x(x + 8)
[Quadratic] Define: x = 0, -8

∴ the roots of the quadratic equation y = x² + 8x is equal to 0 and -8.

In the right triangle shown, angle m∠K=60°m, KL, equals, 2. how long is JL(this is a 30-60-90 triangle)?

Murrr4er [49]

Answer:

Part 1) $JL=2\sqrt{3}\ units$

Part 2) Yes, It is a 30-60-90 triangle

Step-by-step explanation:

The picture of the question in the attached figure

Part 1) How long is JL?

we know that

In the right triangle JKL

$tan(60^o)=\frac{JL}{KL}$ ---> by TOA (opposite side divided by adjacent side)

we have

$KL=2\ units$

$tan(60^o)=\sqrt{3}$

substitute the given values

$\sqrt{3}=\frac{JL}{2}$

$JL=2\sqrt{3}\ units$

Part 2) This is a 30-60-90 triangle?

Find the measure of angle J

we know that

$m\angle K+m\angle J=90^o$ ---> by complementary angles in a right triangle

we have

$m\angle K=60^o$

substitute

$60^o+m\angle J=90^o$

$m\angle J=90^o-60^o=30^o$

therefore

The right triangle JKL is a 30-60-90 triangle

Which of the following ribbon has the greatest cost per inch?

levacccp [35]

You didnt give the sizes of the ribbon so let me help you out. You have to divide the size by total cost, bringing you to the cost per one whatever unit you are using.
