if a bag contains 400 coins,and 33 1 over 2 are nickels, how many nickels are there what percent of the coins are not nickels
iren2701 [21]
Assuming the number is 331/2, or 331 over 2: 
331/2 = 165.5 ÷ 400 = .4138 x 100% = 41.38%
100% - 41.38% = 58.62% not nickels

If the number is 33 1/2, or 33 and one half
33 1/2 = 67.5 ÷ 400 = 0.0838 x 100% = 8.38%
100% - 8.38% = 91.62% not nickels

Multiply.<br><br> (−23)(54)<br><br> Enter your answer as a fraction, in simplified form, in the box.
Sati [7]

Answer: -\frac{1242}{1}

Step-by-step explanation:

By definition, negative numbers, positive numbers and zero are Integers.

It is important to remember the multiplication of signs:

(-)(-)=+\\(+)(+)=+\\(-)(+)=-

You can observe that you must multiply two integers, one of them is negative and the other one is positive. The product will be an integer. Then:

(-23)(54)=-1242

Since any Integer can be written as a fraction, you can rewrite the product by writing -1242 as the numerator and 1 as the denominator.

Then, this is:

=-\frac{1242}{1}

If you can please help me with this question~ the question is the image :)
BaLLatris [955]

Answer:

B

Step-by-step explanation:

Start by using the distance formula to find the raidus

The two points are (-2,1) and (-4,1)

√((-4+2)²+(1-1)²)= 2

The radius is two and we have our center which means we can write

(x+2)²+(y-1)²=4

now it's just a matter of expanding everyhting

x²+4x+4+y²-2y-3=0

x²+y²+4x-2y+1=0

This is equal to B
