Brian purchased 4 items that were $1.00 each. The sales tax rate is 5.5%. How much was Brian's total bill including sales tax?

Answer:

5.52  ×  10^ 3

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 .  If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:

C

Step-by-step explanation:

the third option correctly shows 10 times the square root of 5 (10[tex]\sqrt{5}[/tex])

The expression represents the diagonal length of the rectangle will be 10√5. Then the correct option is C.

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The diagonal length of a rectangular swimming pool can be represented by 10 times the square root of 5. The sentence can be written in the mathematical form given as,

⇒ 10 × √5

⇒ 10√5

The expression represents the diagonal length of the rectangle will be 10√5. Then the correct option is C.

x=4

Step-by-step explanation:

7x-3=5x+5

2x-3=5

2x=8

x=4

The value of x in the expression 7x-3=5x+5 is 4

Given

7x-3=5x+5

Here,

The equation is linear in variable x .

7x-3=5x+5

7x - 5x - 3 = 5

2x-3=5

2x = 5 + 3

2x=8

x = 8/2

x=4

Thus the value of x is 4 .

Answer:

I know how to this in one of two ways and I'm not sure if they're correct but anything to help.

5/6-2/5 would get you 1/3 because if you cross multiply and cross out factors that can go into each you cant pretty much get that answer. ( i think)

or

the common denominator would be 30 multiply 5 by 5 and 2 by 6. 25-12 is 13. How I was taught was find a number that both denominators can go into then multiply by that number. So 6*5= 30 so you would multiply 5 by 5 to get 25.

Hope I explained this well, I don't really think so.

I took the text on edge

Answer: 17

Step-by-step explanation:

Each side has one line on it indicating each side is equal therefore 5y-3= 4y+1. Once you put them equal to each other you solve for y. You start by isolating the variable by inverse operations so you add 3 to both sides which leaves 5y=4y+4 and then you subtract 4y from both sides leaving y=4. Now that you found the value of y you input that value into one of the expression for one of the sides and solve. 5(4)-3= 17

10:00 am EST in Ohio

Step-by-step explanation:

Using the 50 States Time zones attached in the image below.

Chance who lives in Texas has a Time zone of CST (central standard time), while his cousin who lives in Ohio has a Time zone of EST(eastern standard time).

So if it is 5 pm in CST, it will be 6 pm in EST.

Given that;

Chance wants to wish his cousin in Ohio at 9:00 am CST, then the time it will be at his cousin's house when Chance calls to say happy birthday will be:

9:00 am + 1 = 10 :00 am EST in Ohio

The expected value of the ticket is -$1.10

Step-by-step explanation:

Here, we want to find the expected value of the ticket sales

We start by calculating the probabilities

The probability that someone wins the system is 1/2000

The probability that a person loses the system is 1999/2000

So the expected value will be;

(1/2000 * 1,800) - (1999/2000 * 2)

= 0.9-1.999 = -1.099

To the nearest cent, this is -1.10

The equation that can be used to solve for RH is 25/9(DP-T) - 100

Given the formula for the dew point in degrees, Fahrenheit expressed as

To solve for the value of RH, we will make RH the subject of the formula;

Subtract T from both sides:

Multiply both sides by 25

25(DP - T) = 9(100 - RH)

25(DP - T) = 900 - 9RH

25(DP - T) - 900 = 9RH

RH = 25/9(DP-T) - 100

Hence the equation that can be used to solve for RH is 25/9(DP-T) - 100

If fighting is sure to result in victory, then you must fight!

Sun Tzu said that, and I'd say he knows a little more about fighting than you do, pal, because he invented it, and then he perfected it so that no living man could best him in the ring of honor.

Then, he used his fight money to buy two of every animal on earth, and then he herded them onto a boat and then he beat the cra p out of every single one.

And from that day forward any time a bunch of animals are together in one place it's called a 'zoo'!

16x-80+18=4x+22

simplify

16x-62=4x+22

ads 62 to each side

16x=4x+84

subtract 4x from each side

12x=84

divide each side by 12
