If a wall is in a 1/4 in scale drawing is 6 in tall how tall is the actual wall

vekshin1

So 1/4
that measn that the scale wall is 6 inches while the real wall is 4 times 6=24 inches tall (logically, it would be something like 1in/4ft so it woul dbe 24 feet not 24 inches but ok)

so 1/4
6 inches scale drawing is 1/4 of real wall
6=1/4 real
multiply by 4
24=real

asnwer is 24 inches

V2 - 15 = -2v Solve the Quadratic. What are the 2 solutions?

ki77a [65]

Answer:

v=-5 and v=3

Step-by-step explanation:

We are given that

$v^2-15=-2v$

We have to find two solutions of quadratic equation.

$v^2+2v-15=0$

Using addition property of equality

$v^2+5v-3v-15=0$ (By using factorization method)

$v(v+5)-3(v+5)=0$

$(v+5)(v-3)=0$

Substitute each factor equal to 0

$v+5=0$ and $v-3=0$

$v=-5$ and $v=3$

Hence, two solutions of quadratic equation are

v=-5 and v=3

<u>To find the density:</u>

⇒ must find the relationship between the density, mass, and volume

⇒ $Density = \frac{mass}{volume}$

<u>Let's examine the information given:</u>

weight: 1890g
dimensions: 8cm * 5cm* 5cm

<u>Let's first find the volume:</u>

⇒ the volume is the dimensions multiplied together

$Volume = 8cm * 5cm * 5cm = 200cm^3$

<u>LEt's calculate the density now:</u>

$Density = \frac{1890g}{200cm^3} =9.45g/cm^3$

<u>Answer:</u> The density of the copper is <u>9.45g/cm^3</u> or <u>Choice (A)</u>

<u></u>

Hope that helps!
