Answer 1
Answer: I believe it is a Triangle with a base of 100 ft. and a height of 100 ft. 
Yet that's what I learned in class, my teacher isn't paying attention to much of our lessons, so forgive me if this is wrong.

What number is 32% of 1,000

Answers

It is 320 because if you divide 1000 by 10, you would get 100 (which would be equal to 10% of 1000) So if you multiply 100x3=300. then, 2% of 100 is 20, so you add that to 300 then you 320

isnt the answer for qn 3 c?

given that 2 and k are roots of the quadratic equation (x+4) (x-p) = (2-x). find the values of k and p

Answers

the roots of the equation are 2 and k
substituting x=2 in the equation
(x+4)(x-p) = 2-x
(2+4)(2-p) = 2-2
6(2-p) = 0
dividing 6 both side, the answer is
p = 2

substituting x in the equation we 
(x-4)(x-p) = 2-x
x² - 2x + 4x- 8 = 2-x
x² - 2x + 4x -8 -2 -x = 0
x² + 3x - 10 = 0
x² + 5x -2x - 10 = 0
x(x + 5) -2( x + 5) = 0
(x + 5)( x - 2) =0
(x + 5) = 0 or (x - 2) = 0
x = -5 and x = 2
therefor k = -5 and p = 2

What is the unit rate in dollars per hour if u have 3.5 hours equals $10

Answers

Okay. So this is a simple division problem. All you need to do is divide 10 by 3.5. This will figure out how much you spend per single hour. you'll come up with around 2.855. So I'd round down, and say $2.85 per hour.
3.5 hours equal $10
3.5 hours= 7/2 hours

if 7/2 hours = $10
1 hour = (10)/( (7)/(2) ) = 10*(2)/(7) = (20)/(7) dollars

Unit rate = $(20/7) per hour
