Answer:
x = 900 or 1.50 * x = 1,350 (Though I advise you to use x = 900)
Step-by-step explanation:
Divide 1,350 by 1.50 to see that they need to sell exactly 900 bars. We can fact check by using a calculator to do the equation 1.50 * 900 = 1,350.
Answer:
Step-by-step explanation:
we are given a trapezoid
we want to figure out the area
remember that,
where a and b represent the parallel lines and h represents the height
we get from the pic that a and b are 5 and 15 respectively and h is 7
so substitute:
simplify addition:
simplify division:
simplify multiplication:
since we multiply two same units we of course have to use square unit
hence,
By the Pythagorean theorem x^2 + x^2 =h^2. so 2x^2=h^2 or h = x✓2
