Answer: 1,162.9 cm3

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a square pyramid: 1/3 x base area x height

Where

base area = base side length ^2

Replacing with the value given:

Base area = 15.9^2

base area : 252.81 cm2

Back with the volume formula:

V = 1/3 x base area x height

Replacing with the values given and solving for V (volume)

V = 1/3 x 252.81 x 13.8 = 1,162.9 cubic centimeters

Feel free to ask for more if needed or if you did not understand something.

Find a solution to the system. Make sure to write as a coordinate.
RUDIKE [14]

Answer:

x=2, y=3

Step-by-step explanation:

This is a <u>system of equations</u>.

To solve a system of equations, we use the substitution method.

We can plug in the first equation, x=2y-4, into the value for <em>x</em> in the second equation. Now, the second equation looks like this:

2*(2y-4)+y=7

We simplify and solve for <em>y</em>:

→ 4y-8+y=7

→ 5y=15

→ y=3

Now, we plug in the value for <em>y</em>, which is 3, into either equation. I will just use the first equation:

→ x=2*3-4

→ x = 2

Let me know if my explanation is unclear.

GIVING 100 POINTS!!!!
IrinaK [193]

Answer:

As per dot plots we see the distribution of prices is close but majority of prices are concentrated in different zones. So MAD would be more similar by the look.

<u>Let's verify</u>

<h3>Neighborhood 1</h3>

<u>Data</u>

  • 55, 55, 60, 60, 70, 80, 80, 80, 90, 120

<u>Mean</u>

  • (55*2+ 60*2+ 70+ 80*3 + 90+ 120)/10 = 75

<u>MAD</u>

  • (20*2+15*2+5+5*3+15+45)/10 = 15
<h3>Neighborhood 2</h3>

<u>Data</u>

  • 100, 110, 110, 110, 120, 120, 120, 140, 150, 160

<u>Mean</u>

  • (100 + 110*3+ 120*3+ 140 + 150+ 160)/10 = 124

<u>MAD</u>

  • (24+14*3+4*3+16*3+16+26+36)/10 = 20.4

As we see the means are too different (75 vs 124) than MADs (15 vs 20.4).

How to factor x^2-2x-15
olga2289 [7]

Answer:

(x - 5)(x + 3)

Step-by-step explanation:

Given

x² - 2x - 15

Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (- 2)

The factors are - 5 and + 3, since

- 5 × 3 = - 15 and - 5 + 3 = - 2, thus

(x - 5)(x + 3) ← in factored form

A sector of a circle has a central angle to 10° and arc length 28 pi units what is the radius of the circle
Dennis_Churaev [7]

Answer:

Radius = 504units

Step-by-step explanation:

Angle = 10°

Length of arc = 28π units

L = ∅/360 × 2πr

28π = 10/360 × 2πr

28π = 1/36 × 2πr

2πr = 28π × 36

π cancelled off.......

2r = 28 × 36

r = (28 × 36)/2

r = 28 × 18

r = 504units
