Point G is the center of the small circle. Point X is the center of the large circle. Points G, Y, and X are all on line segment

Rama09 [41]

The answer
if Marco wants to create a new circle using GX as a radius,
so GX = r = 10 cm + 16 cm = 26 cm
the area of a circle is

A = pie x r², so the new circle's area should be A = pie x 26² = 676 pie cm²
the true answer is

D. 676 pie cm2

A pan has an original price of $32 but is marked down by 15 percent. Which equation shows the new price of the price

sergejj [24]

We suggest, that the number 32 is 100% - because it is the output value of the task.
We suggest, that x is the value that we are looking for. 
3. If 32 is 100%, so we can jot it down as 32=100%. 
4. We know for sure, that x is 15% of the output value, so we can jot it down as x=15%. 
5. Now, these are the equations are we have.
1) 32=100%
2) x=15%
where the left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
32/x=100%/15%
6. Now we just have to work out the equation, and we'll get the answer that we want.

7. Answer for what is 15% of 32

32/x=100/15
(32/x)*x=(100/15)*x - multiply both sides of the equation by x
32=6.66666666667*x - divide both sides of the equation by (6.66666666667) to get x
32/6.66666666667=x 
4.8=x 
x=4.8

15% of 32=4.8
So, the answer is $4.8
Hope this helped

"Two planes leave the airport at the same time. Plane 1 travels just 9 miles east from

Vika [28.1K]

The answer is 41 miles

Imagine the diagonal distance is called c
Using Pythagorean theorem 40^2 + 9^2 = c^2
1600 + 81 = c^2
The square root of 1681 is 41
So c = 41

A shipment of 50 precision parts including 4 that are defective is sent to an assembly plant. The quality control division selec

natali 33 [55]

Answer:

0.3968 = 39.68% probability this shipment passes inspection.

Step-by-step explanation:

The parts are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$
