This would be k < 50.

This inequality states that k, the price at which Nita wants to buy the new keyboard, is less than 50 dollars.

Answer:

0 ≤ k ≤ 50

Step-by-step explanation:

Here k represents the price of the keyboard ( in dollars ),

Given,

Nita will buy the keyboard,

If the price of the keyboard is under $ 50,

That is,  [tex]k \leq 50[/tex]

Also, the price can not be negative,

⇒ [tex]0 \leq k[/tex]

Hence, the required inequality is,

[tex]0 \leq k \leq 50[/tex]

Answer:

Air left in the Tyre after 1 week = 21.36 psi

Explanation:

 Initial psi level = 38 psi

 Psi level after 1 day = 35 psi

 Percentage of remaining of air per day = (35/38)*100 = 92.10%

 Ratio of remaining air per day = 0.921

 Ratio of remaining air after 7 days = 0.921⁷ = 0.562

 Percentage of remaining air after 7 days = 56.21%

 Air left in the Tyre after 1 week = 38*56.21/100 = 21.36 psi

The student's question is about calculating the expected tire pressure at the end of a week, based on a consistent daily percentage decrease from an initial 38 psi to 35 psi. It involves a mathematical analysis using exponential decay, which is a high school level mathematics topic.

The question involves finding the projected tire pressure after a week given an initial pressure of 38 psi that has decreased to 35 psi in one day. The percentage decrease from 38 psi to 35 psi is calculated first, and then this percentage is consistently applied to find the remaining pressure after 7 days using exponential decay since the tire loses the same percentage of air each day.

Step 1: Calculate the percentage decrease.

Initial pressure (yesterday) = 38 psi

Current pressure (today) = 35 psi

Percentage decrease = ((38 - 35) / 38) x 100%

Step 2: Apply this percentage decrease for 7 days using the formula:

Pn = P0 * (1 - percentage decrease)^n

Where:

Pn is the pressure after n days

P0 is the initial pressure

n is the number of days

By calculating P7, we can find the expected pressure at the end of the week.

Step 3: Substitute the known values and calculate the expected pressure after 7 days.

Hello! I'm guessing you need someone to solve this equation!

4(5x-6)=2(8x+10)

20x-24=16x+20

Add 24 on both sides!

20x=16x+44

Subtract 16x on both sides!

4x=44

Divide 4 by 44

x=11

[tex]-3+7=4[/tex]

[tex]-10-2=-12[/tex]

[tex]4>-12[/tex]

It would be -1.25 degrees at noon.

The percent of change is 45%.

This can be found, by simply dividing 18, by 40, which would give you 0.45, then multiplying 0.45 by 100, to make it a percentage.

I hope this helps!

The answer to this question is 380

Answer:

380 dollar.

Step-by-step explanation:

John earns $437 a week after a 15% pay rise.

Let the initially pay of John be x

x + (15% of x) = 437

x + 0.15x = 437

1.15x = 437

x = [tex]\frac{437}{1.15}[/tex]

x = 380

Initially his pay was 380 dollar.

Integers are positive and negative numbers without decimal points.

The square root of 5 is between 2 and 3

The number is given as:

[tex]\mathbf{n = \sqrt{5}}[/tex]

Evaluate the square root

[tex]\mathbf{n = 2.2361}[/tex]

The above number is greater than 2 but less than 3.

So, we can say that:

2.2361 is between 2 and 3

Hence, the square root of 5 is between 2 and 3

Step-by-step explanation:

Just write the numbers in order (I am assuming from least to greatest).  You can use a number line if necessary.

Solution:

Let starting map of youth center has Dimension (Preimage)

1 unit of y= k units

1 unit of x = t units

The new map of youth center which is 3 times larger than original(Image)

1 unit of y= 3 k units

1 unit of x = 3 t units

Image = 3 × Pre- image

The image is larger than Pre- image.

So, Scale of the new map = 3 × The original dimension of map.

f(x) = 2x + 1

To find the inverse, f^-1(x), of the function:

Put the function as an equation:

y = 2x + 1

Then move x to the left and y to the right;

x = 2y + 1

Then solve for y;

y = x/2 - 1/2

f^-1(x) = y

f^-1(x) = x/2 - 1/2

The area of this tabletop is

6 ft. × 2 ft. = 12 ft.²

Actually neither is greater.

these two numbers are equal to each other.

All because 8.720 has an extra number doesn't mean its greater. Because the number place is 0 is gives no significant value and is therefore the same as 8.72.

The bottom line is...

8.72 = 8.720

To solve this, first add -9b on both sides of the equation to get the variable on only one side of the equation.

2b+4=-18-9b

2b+9b+4=-18-9b+9b

11b+4=-18

Then subtract 4 from both sides of the equation.

11b+4=-18

11b+4-4=-18-4

11b=-22

Divide 11 on both sides of the equation to find the values of b.

Answer:

B) 37%

Step-by-step explanation:

Given,

The total base pay and commission = $ 52561,

While, base pay = $ 23690,

So, the amount of commision = Total base pay and commission - base pay = $ 52561- $ 23690 = $ 28871,

Also, total sale = $77,300,

Hence, the rate of the commission( in percentage )

[tex]=\frac{Commission}{Sale}\times 100[/tex]

[tex]=\frac{28871}{77300}\times 100[/tex]

[tex]=\frac{2887100}{77300}[/tex]

[tex]=37.3492884864\%[/tex]

Option 'B' is correct.

Answer:

0.4545 kgs.

Step-by-step explanation:

Given that 1 kg weighs approximately 22 pounds.

i.e. 1kg= 22 lbs.

We can use this to convert lbs into kg.

22 lbs = 1 kg

Hence 1 lb = 1/22 = 0.04545 kg

Now to find out the equivalent weight for 10lbs,

we have conversion factor as 1 lb= 0.04545 kg

Hence 10 lbs = 10(0.04545) = 0.4545 kgs

Hence 10 pounds written in equivalent kgs would be0.4545 kgs.

The focus is (1,0)  

Hope this helps!

Answer:

focus is (1,0)

Step-by-step explanation:

the focus of a parabola with equation [tex]y^2=4x[/tex]

Focus point lies inside the parabola

To find the focus of a parabola we need to find the vertex

the distance between the focus and vertex is the value of p.

Focus point is (h+p,k)

Where (h,k) is the vertex

Given equation is in the form of [tex](y-k)^2=4p(x-h)[/tex]

Given equation can be written as [tex](y-0)^2=4(x-0)[/tex]

So the vertex is (0,0)

Now we find the value of p

[tex]4p = 4[/tex]

So [tex]p=1[/tex]

Focus is (h+p,k) that is (1,0)

(3.) m=Infinity (equation: x=-2)

The slopes of the lines passing through the given points are: 1. [tex]\((-2,2)\)[/tex] and [tex]\((3,-1)\)[/tex]: [tex]\(m = -\frac{3}{5}\)[/tex]. 2.

To calculate the slope m of a line given two points [tex]\((x_1, y_1)\)[/tex] and [tex]\((x_2, y_2)\)[/tex], you can use the formula:

[tex]\[m = \frac{y_2 - y_1}{x_2 - x_1}\][/tex]

1. For points (-2,2) and (3,-1):

[tex]\[m = \frac{-1 - 2}{3 - (-2)} = \frac{-3}{5}\][/tex]

2. For points (-3,-2) and (2,1):
