Nick paid $2.94 in sales tax on an item that cost $42.00 before tax. At that rate, how much would he pay in sales tax for an ite

Rainbow [258]

2.94 / 42 = 0.07

0.07 x 100 = 7% tax

58 x 1.07 = 62.06

62.06 - 58 = 4.06 Dollar tax

What would the answer be to 4x-6y=36 graphed

xz_007 [3.2K]

Answer:

see the attachment

Step-by-step explanation:

It is convenient to graph this equation using the x- and y-intercepts.

The x-intercept is found where y=0, so ...

4x = 36

x = 9

The y-intercept is found where x=0, so ...

-6y = 36

y = -6

<em>Graph the two points (9, 0) and (0, -6) and draw a line through them</em>. The graph is shown below.

A certain three-cylinder combination lock has 60 numbers on it. To open it, you turn to a number on the first cylinder, then

statuscvo [17]

Answer:

(a) The number of different lock combinations is 216,000.

(b) The probability of getting the correct combination in the first try is $\frac{1}{216000}$ .

Step-by-step explanation:

The lock has three-cylinder combinations with 60 numbers on each cylinder.

The procedure of the opening lock is to turn to a number on the first cylinder, then to a second number on the second cylinder, and then to a third number on the third cylinder.

The numbers can be repeated.

(a)

There are three cylinder combinations on the lock, each with 60 numbers.

It is provided that repetitions are allowed.

Then each cylinder can take any of the 60 numbers.

So there are 60 options for the first cylinder.

There are 60 options for the second cylinder.

And there are 60 options for the third cylinder.

So the total number of possible combinations is:

Total number of combinations = 60 × 60 × 60 = 216000.

Thus, the number of different lock combinations is 216,000.

(b)

The events of getting a correct combinations of the three-cylinder combination lock implies that all the three cylinder are set at the correct numbers.

Each cylinder has 60 numbers.

This implies that there are 60 possible ways to get a correct number for the first cylinder.

The probability of getting the correct number for the first cylinder is:

P (Number on 1st cylinder is correct) = $\frac{1}{60}$ .

Similarly for the second cylinder the probability of getting the correct number is:

P (Number on 2nd cylinder is correct) = $\frac{1}{60}$ .

And similarly for the third cylinder the probability of getting the correct number is:

P (Number on 3rd cylinder is correct) = $\frac{1}{60}$ .

So the probability of getting the correct combination in the first try is:

P (Correct combination in the 1st try) = $\frac{1}{60}\times \frac{1}{60}\times \frac{1}{60}=\frac{1}{216000}$ .

Thus, the probability of getting the correct combination in the first try is $\frac{1}{216000}$ .

What is the surface area of a rectangular prism with a length of 20 inches, width of 40 inches and height of 50 inches? Please h

Marizza181 [45]

Answer:

Step-by-step explanation:

l= 20 in ; b = 40 in; h = 50 in

Surface Area = 2*(lb+bh+hl)

= 2*(20*40 + 40*50 + 50*20)

=2*(800 + 2000 + 1000)

=2*3800

= 7600 square inches
