What is the perimeter of this shape?

Fudgin [204]

Answer:

87 feet

Step-by-step explanation:

Two of the sides here are unknown. The one on the leftmost side is equal to 9, since on the other side it also has a length of 9 feet. The section on the top right has a length of 30-9-9=12 units. Adding all of these values together now, you get a total perimeter of:

30+9+12+9+9+9+9=87 feet

Hope this helps!

What is the value of the expression 3+2x (with an exponent of 3 on top of x) when x = 2?

Ivan

Answer:

A. 67

Step-by-step explanation:

3+2(2)^3

The first thing you would do is distribute the 2 and you would get

3+(4)^3

The next thing you would do is the exponent

3+(4*4*4) = 3+64

Then you would just add 3

64+3= 67

So the answer is A. 67.

A data set includes the following grades: 98, 94, 93, 82, 61, 80. Suppose that 61 is removed from the data. How is the median af

andre [41]

Answer:b

Step-by-step explanation:

A data with values

98,94,93,82,61,80 is given

If we arrange the number according to their values

61,80,82,93,94,98

Median of set

$\frac{82+93}{2}=87.5$

Now if 61 is removed then

80,82,93,94,98 are the remaining data

so New median is 93

So the median is increased by 5.5

Therefore option b is correct
