89.75 scooter:7 1/4% tax
eduard
The question is find the total cost when the price is $89.75 and the tax is 7 1/4%

Total cost = price + tax

Tax  = 7  1/4 % of price

Tax rate = [7 + 1/4] = 7.25 %

Tax = 7.25 % * price = 7.25 % * $89.75 = $[7.25/100] * 89.75 = $6.51

Total cost = $89.75 + $ 6.51 = $96.26

Is it linear or not? 2x+5xy-3=0.
ArbitrLikvidat [17]

The linear equation in slope intercept form: y = mx + b.

We have:

2x+5xy-3=0\qquad\text{subtract 2x from both sides}\\\\5xy-3=-2x\qquad\text{add 3 to both sides}\\\\5xy=-2x+3\qquad\text{divide both sides by}\ 5x\neq0\\\\y=\dfrac{-2x+3}{5x}

This is not a linear equation.

Surface area of a cylinder radius=10 height=15
Virty [35]

Answer:

1570

Step-by-step explanation:

the formula for surface area of a cylinder is:

A= 2πrh + 2πr²

π aka pi = 3.14

r = 10

h = 15

so now plug in the numbers

A = 2(3.14)(10)(15) + 2(3.14)(10²)

A = 942 + 2(3.14)(100)

A = 942 + 628

A = 1570
