The radii of the circle increases by 7.5 cm each ring: 7.5 cm, 15.0 cm, 22.5 cm, and 30.0 cm.
The area if the red target is the area of the largest circle minus the second to the largest circle plus the area of the third largest circle minus the area of the smaller circle
A=pi(30.0)^2 - pi(22.5)^2 + pi(15.0)^2- pi(7.5)^2
A=900pi-506.25pi+225pi-56.25pi
A=562.5pi is approximately 1767 cm^2

schepotkina [342]

Answer:

Step-by-step explanation:

Given:

Brett orders 2 meatball,1 turkey,1 veggie party-size sandwiches.

Each sandwich costs the same amount.

The total amount cost of the sandwiches, including tax, is $54.36.

Question asked:

What is the cost of each sandwich including tax?

Solution:

Let cost of each sandwich including tax = x

<u>Total number of sandwich = 2 + 1+ 1 = 4</u>

<u><em>As each sandwich costs the same amount and total amount of cost of 4  sandwiches, including tax, is $54.36, the equation will be:-</em></u>

x+x+x+x=\$54.36\\4x=\$54.36

By dividing both sides by 4,

x=\$13.59

Thus, the cost of each sandwich including tax is $13.59

Answer:

1.61*10^{8} \\and\\3.3*10^{-7}

Step-by-step explanation:

We can use properties of exponents to solve these equations. Remember that when multiplying exponents, we 'add' them.

--------------------------------------

(2.3*10^{1})(7*10^{6})= \\16.1*10^{7}=\\1.61 *10^{8}

For the next question:

(1.1*10^{-5})(3*10^{-2})=\\ 3.3*10^{-7}

These are your answers!
