The cost of the room before the tax is X.

To get the total cost they multiply the cost of the room x by 1 + sales tax rate.

Total cost would be x(1.05)

To find x divide total cost by 1.05:

Cost of room before tax: 172.20/1.05

Cost: $164

Step-by-step explanation:

x<1

x<(1/3)

Answer:

20000

Step-by-step explanation:

This is because when you round to the signifigant figure, you basically look at any digits at the start of the number, which isn't zero. In this case it would be in the ten thousand 19340. So you round 19340 to the nearest 10 thounsand, which, would be 20000

[tex] {x}^{2} - 3x + 8[/tex]

(Putting value of x = 4)

[tex] = {4}^{2} - 3 \times 4 + 8[/tex]

= 16 - 12 + 8

= 24 - 12

= 12 (Ans)

Answer:

It is 12

Step-by-step explanation:

[tex]f(x) = {x}^{2} - 3x + 8[/tex]

When x is 4, substitute x as 4:

[tex]f(4) = {(4)}^{2} - 3(4) + 8 \\f(4) = 16 - 12 + 8 \\ f(4)= 12[/tex]

Step-by-step explanation:

The new price offers price is less than the offer of 20% discount.

Given that,
Jamil buys a video game for 20% off the original price. He pays $36, excluding sales tax. One week later, he sees an advertisement for $10 off the original price. This is the new sales price.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
percentage of the price paid = 1 - 0.2 = 0.8
Let the original price be x,
According to the question,
36 = 0.8 (x)
x = 36/0.8
x = $45
Since the original price is $45,
As of the new price, the price is $10 so the price becomes $35 which is less than a 20% discount.

Thus, the new price offers price is less than the offer of 20% discount.

Hi! I'm happy to help!

To solve this, we first need to know what scientific notation is. Scientific notation is a way a number is written. You write it using a number ranging from 1 to <10. Then, you multiply this number by [tex]10^{x}[/tex].

In order to make this number reasonable for scientific notation, you have to move the decimal a certain amount of places. In this case you move it 3 places to the right to make your number 2.349. Since we moved it 3 places to the right our x will be -3. (If we'd moved it 3 places to the left, our x would be positive 3.)

So now, we insert our numbers:

2.349·[tex]10^{-3}[/tex]

You write 0.002349 like 2.349·[tex]10^{-3}[/tex], when it is in scientific notation.

Step-by-step explanation:

The basic form for any quadratic function is:

ax^2 + bx + c.

The constant of the 1st term, the x^2 constant, is a, the constant of the second term, the x constant, is b, and the constant, the third term, is c. There are some instances where there will not be a b or c. For example, x^2 + 2, or 3x^2 - 4x. However, there must always be an a, or else the function isn't quadratic.

Answer:

$46,571.67

Step-by-step explanation:

if your description is right and complete, she sold cars on the first 2 days as average for $46975.

and on the third day for $45765

to calculate the total average we need to know the total amount of sales and then divide it by the observation period length (3 days).

how do we get the total sales ?

we know the average of the first 2 days. we don't need to find the exact value for every day, but we know the exact value for these first 2 days : 2×46975 = $93950

as the average of these 2 days = (day1 + day2)/2

46975 = (day1 + day2)/2

day1 + day2 = 2×46975 = 93950

it is not important what two (day) numbers created 93950. we know that this was the total sum of the first two days. and that is enough.

so, we have in total

$93950 on the first 2 days

$45765 in the third day

-------------

$139715 for all 3 days

the average per day is then

139715 / 3 = $46,571.67

Answer:

-13

Step-by-step explanation:

expression =4a-|3b+2c|

subtitute all values in the expression:

=4(-2) -|3(-3)+2(2)|

=-8-|-9+4|

=-8-|-5|

=-8-(5)

=-8-5

=-13

Note:if you need to ask any question please let me know.

The value of the expression from the variables  is -13

From the question, we have the following parameters that can be used in our computation:

4a - |3b + 2cl

Also, we have

a = - 2, b = -3, c = 2, x = 2.1, y = 3, and z = - 4.2.

substitute the known values in the above equation, so, we have the following representation

4a - |3b + 2cl = 4 * -2 - |3 * -3 + 2 * 2|

Evaluate

4a - |3b + 2cl = -13

Hence, the expression from the variables  is -13

Answer:  C)  4

==========================================================

Explanation:

Let's isolate t

-3 > -3t + 6

-3+3t > 6

3t > 6+3

3t > 9

t > 9/3

t > 3

This means any value can replace t such that it's larger than 3.

Something like t = 1/3 = 0.33 won't work since it's not larger than 3.

But something like t = 4 would work because it makes t > 3 true.

That's why choice C is the final answer.

Answer:

Given;

120,000 people voted in 2015.

In 2015, 20% more people voted than 2014.

Therefore:

How many more people voted in 2015 = 20% of 120,000

= 24,000

Total number of people voted in 2014 = 120,000 - 24,000

= 96,000

Ans) 96,000 people voted in 2014.

Answer: sorry i just know no.2

Step-by-step explanation:

2) = soln

h = ?

p = 5

b =9

[tex]h^2 = p^2 + b^2\\h^2 = 3^2 + 9^2\\or, h^2 = 9+81\\or, h^2 = 90\\so, h = \sqrt{90} \\\\[/tex]

Let the angle be x

so

tan x = p/b

tan x = 5/9

x = [tex]tan^{-1} (5/9)[/tex]

so, x = 29.054

rounding off to ten

x = 29.1

now

let the another angle be y

so

90+y+29.1 = 180

29.1 + y = 180-90

y = 90-29.1

so, y = 60.9

the missing side is √90 and missing angles are 29.1° and 60.9°

Answer:

m∠RQS = 72°

m∠TQS = 83°

Step-by-step explanation:

m∠RQS +m ∠TQS = m∠RQT

The two angles combine to make a larger angle

So

m∠RQS = (4x - 20)

m∠TQS = (3x + 14)

(4x - 20) + (3x + 14) = 155

Group the Xs and the constants

4x + 3x - 20 + 14 = 155

Combine like terms

7x - 6 = 155

Add 6 to both sides

7x = 161

Divide by 7 on both sides

x = 23

Check:

4(23) - 20 + 3(23) + 14 = 155

92 - 20 + 69 + 14 = 155

155 = 155

But we need to find m∠RQS and m∠TQS. So plug in x = 23 to the values.

m∠RQS = 4(23) - 20 = 72°

m∠TQS = 3(23) + 14 = 83°

Checking:

72 + 83 = 155

Answer:

16

Step-by-step explanation:

Substitute the value of the variable into the equation and simplify.
