<h2><u>Answer:</u></h2>

The retail price is <u>$15.30</u>

<u />

<h2><u>Step-by-step explanation:</u></h2>
  • To solve this, turn the percentage into a decimal. Do this by dividing it by 100.

        180 ÷ 100 = <u>1.8</u>

  • Then, multiply the supplier price by the decimal

       8.5 × 1.8 = <u>$15.30</u>

Answer: It now costs $15.30 for each shovel (retail price)

Step-by-step explanation:

180% times 8.5 is equal to 1.8 times 8.5 and this is equal to 15.3

If the radius of circle A is 6 units, calculate the area of the shaded region...
meriva

The formula of an area of a triangle:

A_{\triangle}=\dfrac{base\cdot height}{2}

We have:

\triangle_{FDE}:\ base=height=1\\\triangle_{GDH}:\ base=height=9

substitute:

A_{\triangle_{FDE}}=\dfrac{1\cdot1}{2}=0.5\\\\A_{\triangle_{GDH}}=\dfrac{9\cdot9}{2}=40.5

The formula of an area of a circle:

A_O=\pi r^2

We have r=6

Substitute:

A_O=\pi\cdot6^2=36\pi\approx36\cdot3.14=113.04

The area of the shaded region

A=A_O-(A_{\triangle_{FDE}}+A_{\triangle_{GDH}})\\\\A=113.04-(0.5+40.5)=113.04-41=72.04\ u^2

You launch a water balloon. The function h=-0.08t^2+1.6t+2 models the height h (in feet) of the water balloon after t seconds. W
stellarik [79]

Answer:

The initial height of the balloon is 2 feet.

Step-by-step explanation:

The height of the balloon in feet after t seconds is given by the following equation:

h(t) = -0.08t^{2} + 1.6t + 2

What is the initial height of the balloon?

This is h when t = 0, that is, h(0). So

h(0) = -0.08*0^{2} + 1.6*0 + 2 = 2

The initial height of the balloon is 2 feet.

Choose the point-slope form of the equation of this line.​
igor_vitrenko [27]

Answer:

y= -5x +7

Step-by-step explanation:

We can see points on the graph:

  • (2, -3) and (3, -8)

The function in general form is:

  • y= mx+b

Let's find the slope and y-intercept as per identified points on the graph:

  • m= (y1-y1)/(x2-x1)
  • m= (-8+3)/(3-2)= -5

b= y- mx

  • b= - 3 -(-5)*2= -3 +10= 7

Based on the found values of m and b, the given line is:

  • y= -5x +7
