Answer:
$7.20
Step-by-step explanation:
If 8 pens cost $3.84, we need to find out how much ojne pen costs.
To find out the cost of one pen we need to divide $3.84 by 8.
$3.84 / 8 = $0.48
1 pen cost $0.48
We then need to work out the cost of 15 pens. So from using the information that one pen costs $0.48 we can multiply that by 15 to find out the answer.
$0.48 x 15 = $7.20
15 pens cost $7.20
Given :
Susan wanted to share her 37 seashells with her two younger brothers.
To Find :
If she divided her seashells between the three of them, how many would each person get.
Solution :
Let, each person will get x seashells.
So,
But as we know seashells cannot be in decimal.
Therefore, each person will get exactly 12 shells.
Answer:
3(-x^2-6x+4)
Step-by-step explanation:
-3x^2 - 18x + 12
-3x^2 - (2 x 3^2) x + 2^2 x 3
3 (-3x^2 over 3 - 2x3^2 times x over 3 + 262 x 3 over 3)
3(-(x^2) - (2 x 3^2-1 times x) +2^2
3(-x^2 - (2 times 3x) +4)
3(-x^2-(6x) + 4)
3(-x^2 - 6x + 4)
Answer:
- P = -390t +48,000
- P = 43,710 in 2003
Step-by-step explanation:
A) We are given two pairs of (t, P): (0, 48000), (8, 44880). We can use these with the 2-point form of the equation of a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
P = (44880 -48000)/(8 -0)(t -0) +48000
P = -3120/8t +48000
P = -390t +48000
__
B) In 2003, t = 11, so we have ...
P = -390(11) +48000 = 43710
The population in 2003 is predicted to be 43,710.
