Step-by-step explanation:

A circle with radius of 2 cm sits inside a circle with radius of 4 cm.

What is the area of the shaded region?

Round your final answer to the nearest hundredth.

Assuming the shaded region is the region in between both circles this is how you solve it:

Find the area of the 2cm circle then the area of the 4cm circle. Then subtract the area of the 2cm circle from the 4cm circle. To find the area of a circle use the equation A = πr^2. The area of the smaller circle given the values is 4π or 12.5663706144. The area of the bigger circle given the values is 50.2654824574. Then subtract and you get 37.6991118431. Which is approximately 37.70.

Which equation is in point-slope form for the given point and slope?

Neko [114]

First,we need to understand the point-slope form:
$y1 - y2 = m(x1 - x2)$
Where x and y are the coordinates and m is the slope.

Put the above information into the equation:

y-(-6)=-3/4(x-2)
y+6 = -3/4 (x-2)

Therefore the answer is C.y+6 = -3/4 (x-2).

Hope it helps!

The Johnsons bought 3 burrito meals and 4 taco meals for $48. The Sloans bought 6 burrito meals and 2 taco meals for $60. How mu

faust18 [17]

Answer:

Each burrito meal cost 8$

Each taco meal cost 6$

Step-by-step explanation:

Johnsons= 3b +4t =48

Sloans= 6b+2t=60

multiple johnsons by -2

so, now the johnsons are -6b+-8t=-96

add that to the sloans so, -6b+6b-8t+2t=-96+60

the b's cancel eachother out, so you are left with -6t= -36

divide each side by -6 and you will get t=6

then you can pick either formula, lets say sloans this time

so, 6b + 2(6)=60 so, 6b+12=60, subtract 12 from each side, to get 48

so 6b=48, divde each side by 6 and you will get b=8
