A jackets original price is $65.00 .It is on sale for 40% off. you have to pay 5% sales tax What is the final price fir the jack

lesya [120]

Hello!

There is a discount of 40%, which means that we will be subtracting 40% of the price, and then sales tax is basically additional money added to the price, so we will be adding that.

65.00 * 40% = 26

65.00 - 26 = 39

So, the discounted price is $39. Now we must add tax on that.

39 * 5% = 1.95

39 + 1.95 = 40.95

The final price of the jacket is $40.95.

Skylar owns a trucking company. For every truck that goes out, Skylar must pay the driver $11 per hour of driving and also has a

jeyben [28]

Answer:

The set of needed equations is

h = 30 m

11 m + 3 h = 909 where

the driver drove for m hours.

h : distance covered in m hours

Step-by-step explanation:

Here, according to the question:

The per hour rate of driver = $11

The gas maintenance expense = $3 per mile.

The total distance covered by drives is 30 miles per hour.

The total expenses paid to driver = $909

Now, let us assume the driver drove for m hours.

The average speed of driver was 30 miles / hour

⇒ Driver covers 30 miles in 1 hour

SO, distance covered in m hours = h = m x 30 = 30 m

or, h = 30 m

So,according to the question, the total amount paid :

Charges of m hours driving + maintenance charges for h miles

= 11 m + 3( h)

or, 11 m + 3 h = $909

Hence the set of needed equations is

h = 30 m

11 m + 3 h = 909

On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases from quadrant 2 into quadrant 1. It

dusya [7]

Answer:

f(x) = $2^{(3x)}$

Step-by-step explanation:

The given options are,

a) f(x) = $2^{(3x)}$

b) f(x) = $({\frac {1}{2}})^{3x}$

c) f(x) = $2 \times ({\frac {1}{3}})^{x}$

d) f(x) = $\frac {1}{2} \times ({\frac {1}{3}})^{x}$

Now, among the given options only option (a) satisfies the criteria stated in the question i. e.,

1. f(x) → 0 as x → - ∞ and

2 f(0) = 1

so, the correct answer is,

f(x) = $2^{(3x)}$

How to find the point slope form with the slope of 3 and the point of -2/6

Levart [38]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \:y-6 = 3(x + 2)$

____________________________________

$\large \tt Solution \: :$

Equation of line in point - slope form :

$\qquad \tt \rightarrow \:y-y_1 = m(x - x_1)$

$\tt \:m = slope=3$

$\tt y_1 = y \: \: coordinate \: \: of \: \: point = 6$

$\tt \:x_1 = x \: \: coordinate \: \: of \: \: point = - 2$

Here :

$\qquad \tt \rightarrow \:y - 6 = 3(x - ( - 2))$

$\qquad \tt \rightarrow \:y - 6 = 3(x + 2)$

Dennis has three identical cylinders filled with water. How many cones should he be able to fill with the water if the cones

Brut [27]

Answer:

3 cylinder will fill 9 cones with water

Step-by-step explanation:

This problem bothers on mensuration of slides, cone and cylinder

We know that the

Volume of a cylinder = πr²h

Volume of a cone = 1/3(πr²h)

Given that both cylinder and cone has same height and radius

From the given expression we can deduce that the cone is 3 times smaller than the cylinder in volume

So if 1 cylinder will fill 3 cones

Then 3 cylinders will fill x cones

By cross multiplication we have

x= 3*3cones

x= 9 cones

Hence 3 cylinder will fill 9 cones with water
