0.10x+0.25(x+3)=1.80 
<span>0.10x+0.25x+0.75=1.80 </span>
<span>0.35x=1.80-0.75=1.05 </span>
<span>x=1.05/0.35=3 </span>
<span>Therefore,Vonda has 3 dimes and 6 quarters with her </span>

Please help !Suppose that the height in centimeters of a candle is a linear function of them out of time in hours it has been bu
Elan Coil [88]

Answer:

  17.8 cm

Step-by-step explanation:

In the 17 hours between heights of 18.6 cm and 15.2 cm, the candle lost 3.4 cm in height. That is, the height decreased at the rate of ...

  (-3.4 cm)/(17 h) = -0.2 cm/h

In the 4 hours between 12 hours and 16 hours of burning time, the candle will have changed its height by (4 h)(-0.2 cm/h) = -0.8 cm.

The height at 16 hours of burning is then 18.6 cm -0.8 cm = 17.8 cm.

Write the equation in standard form<br><br> y = -10x + 6
Mumz [18]
Step (1) Flip the equation

−10x+6=y


Step (2) Add -6 to both sides

−10x+6+−6=y+−6

−10x=y−6

Step (3) Divide both sides by -10

−10x−10=y−6−10

ANSWER
x =  \frac{ - 1}{10} y +  \frac{3}{5}

PLEASE HELP

Given that the radius of the circle is 6 cm.

The central angle is 120°

We need to determine the length of AB.

<u>Length of AB:</u>

The length of AB can be determined using the formula,

{arc \ length}=2 \pi r\left(\frac{\theta}{360}\right)

Substituting \theta=120 and r=6 in the above formula, we get;

arc\ length}=2 \pi (6)\left(\frac{120}{360}\right)

Simplifying the values, we get;

arc\ length}=2 \pi (6)\left(\frac{1}{3}\right)

arc\ length}=12 \pi \left(\frac{1}{3}\right)

arc\ length}=4 \pi

Substituting π = 3.14, we have;

arc\ length}=4(3.14)

arc\ length}=12.56

Thus, the arc length of AB is 12.56 cm
