A rock weighs 80 g on a triple beam scale. The same rock is then gently placed inside a graduated cylinder containing 30 mL of w

ater. If the water level in the graduated cylinder rises to 75 mL. What is the density of the rock

Answer:

  • 1.78 g/cm³

Step-by-step explanation:

<u>80 g rock displaces water:</u>

  • 75 ml - 30 ml = 45 ml = 45 cm³

<u>Density = mass / volume:</u>

  • d = 80 g / 45 cm³
  • d = 1.78 g/cm³ (rounded)

7w-180=52w what does w equal
BartSMP [9]

Answer: w= -4

Step-by-step explanation:

7w-180=52w

Subtract 7w on both sides.

-180=45w

Divide both sides by 45.

-4=w

SOMEONE HELP BECAUSE I DONT GET THIS
Leno4ka [110]

Answer:

x = 18

m<A = 166°

Step-by-step explanation:

The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.

7x + 40 = 3x + 112

4x = 72

x = 18

m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166

Ich variable:<br> 12. 900 + C = 60 what does c =
Lemur [1.5K]
C = -840

Isolate C by subtracting 900 on both sides:
C = 60-900
Which then gives u C = -840

Simplify the function f(x)= 1/2 (27) 2x/3. Then determine the key aspects of the function
jeyben [28]
The given expression is:

f(x)= \frac{1}{2}(27)^{ \frac{2x}{3} } \\  \\ &#10;f(x)= \frac{1}{2}((27)^{ \frac{2}{3} })^{x}      \\  \\ &#10;f(x)=  \frac{1}{2}(9)^{x}

From the above equation, we can answer all the 4 questions.

a) Initial value occurs when x = 0

So,

f(0)= \frac{1}{2}(9)^{0}= \frac{1}{2}

So, the Initial value of the function is 1/2.

b) Simplified Base:
The base of an exponential function is the term which contains the exponent.
From the simplified equation, we can see that the base has been simplified and is equal to 9.

So, the simplified base is 9

c) Domain:
From the equation we can see that there is no such value which makes the function undefined. So all reall numbers are included in the Domain.

So, Domain is Set of All real numbers. 
In Interval notation this can be expressed as: (-∞,∞)

d) Range:
Range is the set of all y values that a function can take. Since the graph is not shifted vertically up or down, the range will be the set of all real numbers greater than zero.

So, Range is equal to All real numbers greater than 0.
In Interval notation, this can be expressed as (0,∞)
