Step-by-step explanation:
5: 260 = 250(1.04)^t
Divide both sides by 250, and we get 1.04. So t must be 1.
6: x + 45 = x(1.03)²

Answer:
24
Step-by-step explanation:
Answer:
About 13.86
Step-by-step explanation:
64 x 3 = 192
[tex]\sqrt{} 192[/tex] = 13.8564064606
If you were asking what [tex]\sqrt{64}[/tex] multiplied by 3 was, that answer would be 24. I read it as if you were asking what [tex]\sqrt{64 x 3}[/tex] is. :)

Answer:
each tank = 54 + (750÷ 1000) liter = 54.75L
so the capacity of the four tanks = 4x 54.75 = 219litre
Step-by-step explanation:
1) change 750 ml int litre which is equal 750÷1000 = 0.75L

A hoodie is on sale for $48. This sale price is 80% of the original price. What was the original price of the hoodie?
Answer: 60 dollars
===============================================
Work Shown:
x = original price
y = sale price
The sale price is always smaller than the original price, so y < x.
The equation linking the two variables is
y = 0.8x
since 80% = 80/100 = 0.8
We know the sale price is $48, which means y = 48. This leads to:
y = 0.8x
0.8x = y
0.8x = 48
x = 48/0.8
x = 60
The original price was $60
Note: since the sale price is 80% of the original price, this must mean that we have a 20% discount (100% - 80% = 20%)
Determine which function has a greater change of rate.
Be sure to show work as well.
Answer:
A
Step-by-step explanation:
You need to find the slope in A. y = x + (4x - 1) = 5x -1. The slope is 5.
In B, as x increases 1 unit, y increases 1 unit. Therefore, the rate of change is 1/1 = 1
Conclusion: In A the rate of change is 5 and in B the rate of change is 1.
Therefore, A has a greater rate of change
