Answer is c because I got it write on the practice quiz I think I did atleast
Because it is 3/4 of the entire bag, set it up as a ratio
3:4 = 4.5:w
<span>
</span>cross mult.
3w= 4.5(4)
3w = 18
divide 3 both sided
18/3=6
w=6
originally there was 6lbs of food.
Answer:
V = 4645.63 cubic m
Step-by-step explanation:
the drum is cylindrical and the formula for the volume of a cylinder is:
V = πr²h
V = π(6.5)²·35
V = 4645.63
Here, we want to select which of the fractions are rational
To get this, we need to understand what rational numbers are
Rational numbers are numbers that can be expresed in form a/b where the value of b is not equal to zero
From the options in the question, we can see that all these numbers are directly expressed as fractions in the form a/b with none of the denominators being eual to zero
This means all the given fractions are rational
Answer:
99
Step-by-step explanation:
You can solve it by Squaring/multiply 18 by itself and 15 by itself then subtract them both:
(18 × 18) - (15 × 15)
324 - 225
99
You could also do difference of two squares:
(x² - y²)
= (x + y) (x - y)
= (18 + 15) (18 - 15)
= (33) (3)
= 99
