The number is even. It is nit divisible by 3. It is not divisible by 5. It is not greater than 9^2. Is it not less than 8^2. Wha

TEA [102]

Answer:

64, 68, 74, 76

Step-by-step explanation:

Ok so in a confusing way, the last two statements are telling you that the number is greater than 8^2, which is 64, and the number is less that 9^2, which is 81.

The number has to be even, so I will list the even numbers between those two numbers:

64, 66, 68, 70, 72, 74, 76, 78, 80.

It cannot be divisible by 3, which rules out 66, 72, 78

64, 68, 70, 74, 76, 80 remains

It cannot be divisible by 5, which rules out 70 and 80

64, 68, 74, 76 are the possible answers,

*Note: I believe I did this right, but because of the tricky wording of the last two statements, 64 may not be included.

a rectangles width is 11 feet more than its length if the perimeter is 54 feet what is the length and width ?

Sloan [31]

Answer:

Width = Length + 11

Perimeter:

(2 × Width) + (2 × Length) = 54 Feet

Substitute Width = Length + 11,

(2)(Length + 11) + (2 × Length) = 54

Length + 11 + Length = 54 ÷ 2

2Length + 11 = 27

2Legth = 27 - 11 = 16

Length = 16 ÷ 2 = 8

Width = 8 + 11 = 19
