6- ounce packet rate = $0.72 .
In order to find the one ounce rate, we need to divide $0.72 by 6.
On dividing 0.72 by 6, we get $0.12.
<em>Therefore, first unit rate is $0.12 per ounce.</em>
3- ounces packet rate = $0.27.
In order to find the one ounce rate, we need to divide $0.27 by 3.
On dividing 0.27 by 3, we get $0.09.
<em>Therefore, second unit rate is $0.09 per ounce.</em>
<h3>So, we can say that each pair of rates is not equivalent. </h3>
Answer:
40
Step-by-step explanation:
The volume of a prism is the base area * height. We know the base area is 15 and the volume is 600, so the height must be 600/15 = 40.
Answer:
Step-by-step explanation:
hello :
let y the length and x the width
A the area and P the perimeter
so : A= xy and P = 2(x+y) ....y > x and x >0 ; y>0
xy = 1764 ...(1)
y = x +13....(2) put this value in (1) : x (x+13) = 1764
x²+13x -1764 = 0 ...quadratic equation
calculate : Δ = b² -4ac a =1 and b =13 and
c = -1764
Δ = (13)² - 4(1)(-1764) = 169 +7056 = 7225=85²
X1 =(-b-√Δ)/2a =(-13-85)/2 < 0 refused (x >0)
X2 =(-b+√Δ)/2a =(-13+85)/2 = 72/2 = 36
so : x= 36 put this value in (2) : y = 36+13 = 49
the perimeter is : P = 2(x+y)
P = 2(36+49) = 170 m
