You do a little method called cross multiplication and helps to solve proportions and how to find percents in your case. My iPad won't really show fractions but I'll use the dash marks.
1/10=?/100
Multiply 1 by 100 and you get 100 and then divide by 10 which will get you 10 percent.
Another example would be 4/5=?/100
Again you do cross multiplication and it would be 4 times 100 and you get 400 and then you divide by 5 and the answer is 80 percent.

Answer:
area of trapazoid= 1/2 × b× h
so = 1/2×9×15
=1/2×135
=67.5cm
Answer:
Option D.(60, 135)
Step-by-step explanation:
Let
x -----> the number of acres of peas
y ----> the number of acres of carrots
we know that
The inequality that represent the problem is equal to

so
<em>Verify each case</em>
case A) (-50,160)
substitute the value of x and the value of y in the inequality and then compare the result

----> is true
The point is a solution for the inequality, but is not a viable solution because the number of acres can not be a negative number
case B) (80,160)
substitute the value of x and the value of y in the inequality and then compare the result

----> is not true
therefore
The point is not a solution
case C) (75,-200)
substitute the value of x and the value of y in the inequality and then compare the result

----> is true
The point is a solution for the inequality, but is not a viable solution because the number of acres can not be a negative number
case D) (60,135)
substitute the value of x and the value of y in the inequality and then compare the result

----> is true
therefore
The point is a viable solution
2x^2(4x+5) + 5(4x+5)
(2x^2+5(4x+5)
Answer:
use y=mx+b format to find the y-intercept
Step-by-step explanation:
the y-intercept is b of course
the y-intercept is where the y meets a line
the equation will be _=_x+_
