Answer: 177.5


Step-by-step explanation:so to find to area u need to multiply 16 times 16,which gives u a area of 256. Now to find to Area of circle u need to do 5*5 becuse 5 is the radius,and that is 25. 25*3.14=78.5. So we need to subtract 256-78.5=177.5.

The perimeter of the rectangle is 48 feet. The length is 16 ft. What is the<br> width?
asambeis [7]

is the length both sides already or just on one side?

because if the 16ft. is only on one side, and the sum of the both sides are 32ft, i think the width of the rectangle must be 16ft, which means 8ft from the first side and 8ft from the second side.

but if the 16ft. is the sum of both sides, which means 8ft from the first length and 8ft from the second length, then the answer for the width is 16ft, for each side of the width. 16 for the first width, and 16 for the second width.

is my explanation too complicated?? sorry hehe.

Selma spent
Taya2010 [7]

Answer:

30%

Step-by-step explanation:

Selma spent 3/10 of her allowance on a new backpack.

Hence, the percent of her allowance that she spent is calculated as:

Fraction of allowance spent on Backpack × 100

= 3/10 × 100

= 0.3/1 × 100

= 30%

Therefore, Selma spent 30% of her allowance on a new backpack.

Given z=4+3i evaluate z​
DerKrebs [107]

Answer:

5

Step-by-step explanation:

Assuming we want to evaluate |z|, given that, z=4+3i.

Then, by definition of modulus,

|x + yi|  =  \sqrt{ {x}^{2} +  {y}^{2}  }

|4+ 3i|  =  \sqrt{ {4}^{2} +  {3}^{2}  }

|4+ 3i|  =  \sqrt{ 16+  9 }  \\ |4+ 3i|  =  \sqrt{25 }  \\ |4+ 3i|  = 5

Therefore the modulus be of the given complex number is 5 units
