The correct answer is 75% increase.
The number 4 to 7 is increasing not decreasing since the number is higher than before.
Also 4 x 0.75 = 3 and 4 + 3 = 7 so it’s and increase of 75%
Hope this helps.
Answer:
5.83
Step-by-step explanation:
5x + 6.26 = 35.41
-6.26 -6.26
5x = 29.15
x = 5.83
Each bag of onions costs $5.83.
100 - 83.5 = 16.5 [three significant figure]
2.45 + 18.3 = 20.75 [four significant figures]
Option b is correct.
Answer: π(10^2)(10) − 1/3π(10^2)(10)
Step-by-step explanation:
Container A is a cylinder so the equation is π(r^2)(h)
Container B is a right cone so that equation is 1/3π(r^2)(h)
You would plug in the numbers and then subtract A from B
Answer:
x=-2 and y=2
Step-by-step explanation:
Do simultaneous equations
-8x + 4y = 24 <em>(multiply everything in the equation by -7)</em>
-7x + 7y = 28 <em>(multiply everything in the equation by 8)</em>
56x - 28y = -168
-56x + 56y = 224
<em>(add equations, ie add 'x' parts, 'y' parts, and numerical parts)</em>
<em> </em>28y = 56
∴y = 2
-8x + 4y = 24
-8x + 4(2) = 24
-8x = 16
∴x=-2
Lemme know if you have questions :D
