Answer:
8 two-point shots,
4 three-point shots
Step-by-step explanation:
let 'x' = 2-pt shots
let 'y' = 3-pt shots
system of equations can be used as follows:
x + y = 12
2x + 3y = 28
if we solve for 'y' we get 'y = 12-x'
use '12-x' instead of 'y' in the equation 2x + 3y = 28 to solve for 'x':
2x + 3(12-x) = 28
2x + 36 - 3x = 28
-x + 36 = 28
-x = -8
x = 8
if x+y = 12, then y = 4
You could set up a ratio given that it is a 5% solution (5% of the total, not 5% of water.
5/100 = x/473 You need to find out how much is vinegar. Cross multiply
5 * 473 = 100 x Find the number on the left.
2365 = 100 x Divide by 100
2365 / 100 = x
x = 23.65 mL of vinegar.
The water is found by subtraction
473 - 23.65 = 449.35 mL of water.
Answer:
15 to 27 (which is equal to 5:9)
Step-by-step explanation:
The ratio 15 to 12 indicates that there is a total of 27 people in the classroom (15+12). So, if you want boys to total students, it's 15 to 27.
You can divide each of these by 3 to simplify it and get 5:9.

Answer:
Part 1:
P₂(0.07)=0.93245≈
Part 2:
Error=
Step-by-step explanation:
Given:
P₂(x)=
Solution:
Part 1:
P₂(x)=
We have x=0.07
Put Value of x in above Equation:
P₂(0.07)=
P₂(0.07)=0.93245≈
Part 2:
=0.93239382 (Calculated using Calculator)
Error=|-P₂(0.07)|=|0.93239382-0.93245|=0.00005618
Error=|0.93239382-0.93245|
Error=0.00005618
Error=
