Answer:

r = -3/7.

Step-by-step explanation:

To solve this equation, we multiply both sides by 6/7. This is the reciprocal of the coefficient in r (7/6) and will "cancel out" the expression. So:

-1/2 x 6/7 = -6/14 = -3/7.

As such, r = -3/7.

I hope this helps!

Answer:

A

Step-by-step explanation:

We can break down what each term represents in the equation

60 is the constant. This is the base price that is paid regardless of workers and hours needed

Then there is 12nh. 12 represents the cost per hour for one worker. If the job takes only one hour, then it is 12 dollars per worker. Similarly, if the job only takes one person, then it is 12 dollars for each hour.

The most accurate answer is A

The value of y is directly proportional to the value of x when x=512 y=128 what is the value of y when x=64
luda_lava [24]
Answer: y=16
explanation: y=128 when x=512, so to get the value of y, you need to divide 512/64=8. dividing 512(x) by 8 times gets 64, so you need to divide 8 on the other side(y). 128/8=16. hope this helped!

A beach ball has a mass of 5 g and a volume of 20 cm3. What is the object's density? A. 4 g/cm3 B. 100 g/cm3 C. 0.25 D. g/cm3 4
Triss [41]
<h2>Hello!</h2>

The answer is:

C.  0.25\frac{g}{cm^{3} }

<h2>Why?</h2>

The density is the relation between the mass and the volume of an object. We are given four options to chose, and we can find the correct one by doing the following calculations:

Density=\frac{mass}{volume}=\frac{5g}{20cm^{3}}=0.25\frac{g}{cm^{3}}

So, the correct options is C.  0.25\frac{g}{cm^{3} }

Have a nice day!

In the rectangle below, E1=2x -2, FH=3x+6, and m 4IHG =35°.Find Gl and m LIEH
Tpy6a [65]

Recall that the diagonals of a rectangle bisect each other and are congruent, therefore:

\begin{gathered} FH=2EI, \\ GI=EI. \end{gathered}

Substituting the given expression for each segment in the first equation, we get:

3x+6=2(2x-2).

Solving the above equation for x, we get:

\begin{gathered} 3x+6=4x-4, \\ 3x+6+4=4x, \\ 3x+10=4x, \\ 4x-3x=10, \\ x=10. \end{gathered}

Substituting x=10 in the equation for segment EI, we get:

EI=2*10-2=20-2=18.

Therefore:

GI=18.

Now, to determine the measure of angle IEH, we notice that:

\Delta HFG\cong\Delta GEH,

therefore,

\measuredangle GHF\cong\measuredangle HGE.

Using the facts that the triangles are right triangles and that the interior angles of a triangle add up to 180° we get:

m\measuredangle IEH=90^{\circ}-35^{\circ}=55^{\circ}.

<h2>Answer: </h2>\begin{gathered} m\operatorname{\measuredangle}IEH=55^{\operatorname{\circ}}, \\ GI=18. \\  \end{gathered}
