If there are n coins, then the smallest (minimum) amount of coins we need to flip is 1. The reason why is because the best case scenario would be flipping all heads except the last coin which is tails. This scenario is rare if n is large, but still possible.

A. Find x. The figure is not drawn to scale.
riadik2000 [5.3K]

Step-by-step explanation:

a) The circumference of a circle is 360 degrees. so:

7x+15+8x+6x+30=360

21x+45=315

21x=135

x=<u>15</u>

b) This means 7(15)+15=120, 8(15)=120, and 6(15)+30=120. Thus, by the inscribed angle theorem, all the angles measure 60 degrees, and the triangle is thus <u>equilateral</u> and <u>isosceles</u>.

A golf cart priced at $5,600 was on slae for 20% off.The sales tax rate is 6%.What is the sale price of the golf cart,including
Norma-Jean [14]

Answer:

$4748.80

Step-by-step explanation:

First, find the cost with 20% off, by multiplying the price by 0.8

5600(0.8)

= 4480

Find the cost with tax, by multiplying this by 1.06

4480(1.06)

= 4748.8

So, the sale price, including tax, is $4748.80

Are any solutions possible for this problem..
dimulka [17.4K]

The equation: -2(x+3)=-2x-6, is simplified with distribution of parentheses: -2x-6=-2x-6.

Now add 2x to both sides and get: -6=-6.

The numbers are equal therefore the solution to the equation x can be any number x\in\mathbb{R}.

The line represented by the equation 4y + 2x = 33.6 shares a solution point with the line represented by the table
mamaluj [8]

Answer:

The solution of this system is

(4). (6.0,5.4)

Step-by-step explanation:

First we have to find the equation of the line represented in the table; for that we have to find it's slope m and it's y-intercept b and then write it in the following form:

y=mx+b

The slope m of the line we get from first two points:

m=\frac{3.8-3.2}{(-2)-(-5)} =0.2

thus we have

y=0.2x+b

we find b by putting the point (2,4.6) into the function:

4.6=0.2(2)+b

b=4.6-0.4=4.2

Thus we have

y=0.2x+4.2

Now we have to find where this line intersects with 4y+2x=33.6; to do this we just substitute y with y=0.2x+4.2:

4(0.2x+4.2)+2x=33.6

0.8x+16.8+2x=33.6

\boxed{x=6 }

<em>We have the x-coordinate of  the intersection.</em>

We find the y-coordinate by substituting x=6 into y=0.2x+4.2:

y=0.2(6)+4.2=5.4

\boxed{y=5.4}

Thus the solution to the system is

\boxed{(x,y)=(6, 5.4)}

which is option 4.
