Which is the length of the arc MPN expressed in terms of pie?

To calculate the total snowfall in January and February, we add the snowfall measurements for both months. The total snowfall for January (8.6 inches) and February (2.8 inches) is 11.4 inches.

The question involves adding the amounts of snowfall for two different months, which is a basic arithmetic operation covered in mathematics. To find the total snowfall in January and February combined, we simply add the snowfall totals for each month.

According to the given information, there were 8.6 inches of snow in January and 2.8 inches in February.

Total snowfall for January and February combined is 8.6 + 2.8 = 11.4 inches.

If we consider the additional provided information, we can infer that since the schools closed and more than three inches of snowfall triggers a closure, it's reasonable to assume that in at least one of these months the snowfall was above three inches.

It was actually 8

Step-by-step explanation:

I don't actually know why it's 8, I just got it wrong on ixl. So yeah, it's 8

Melissa and her younger sister are 5 meters apart.

In this scenario, Melissa's younger sister is directly to her right and her older brother is 12 meters directly ahead of her. Since her brother and sister are 13 meters apart, we can use the Pythagorean theorem to find the distance between Melissa and her younger sister.

Let's call the distance between Melissa and her younger sister 'x'. We can set up a right triangle with Melissa, her brother, and her sister as the vertices.

Using the Pythagorean theorem, we have:

x^2 + 12^2 = 13^2

Simplifying the equation, we get:

x^2 + 144 = 169

x^2 = 169 - 144

x^2 = 25

Taking the square root of both sides, we find:

x = 5

Therefore, Melissa and her younger sister are 5 meters apart.

The function is not invertible if you think of it as

[tex]f:\mathbb{R}\to\mathbb{R}[/tex]

because it is not injective: [tex]f(x)=f(-x)[/tex]

So, if we restrict the domain to the positive numbers only:

[tex]f:\mathbb{R^+}\to\mathbb{R}[/tex]

Note that the range is actually [tex][9,\infty)[/tex], so we can be more precise and write

[tex]f:\mathbb{R^+}\to[9,\infty)[/tex]

To find the inverse, we solve the expression for x:

[tex]y=x^2+9 \iff y-9=x^2 \iff x=\pm\sqrt{y-9}[/tex]

But since we restricted to positive values of x, the inverse is

[tex]x=\sqrt{y-9}[/tex]

To find the inverse of the function f(x) = x² + 9, swap x and y and solve for y. The inverse function is f^(-1)(x) = ± √(x-9), with a domain restricted to x ≥ 9.

To find the inverse of the function f(x) = x^²+ 9, we need to switch the roles of x and y and solve for y. The given function is y = x² + 9. Swap x and y to get x = y² + 9. Rearrange this equation to solve for y in terms of x: y² = x - 9. Taking the square root of both sides gives us y = ± √(x-9). Therefore, the inverse function is f^(-1)(x) = ± √(x-9), and the domain is restricted to x ≥ 9.

Step-by-step explanation:

The solution for given equations [tex]-7x+2y=5[/tex] and [tex]3x-5y=-5[/tex] are x = -0.517 and y = 0.6896.

Step-by-step explanation:

The given is,

                            [tex]-7x+2y=5[/tex]..........................(1)

                              [tex]3x-5y=-5[/tex]........................(2)

Step:1

         Equation (1) is multiplied by 5    ( Eqn(1) × 5)

                        [tex]-35x+10y=25[/tex].........................(3)

         Equation (2) is multiplied by -2  ( Eqn (2) × -2 )

                          [tex]-6x+10y=10[/tex].........................(4)

Step:2

         Subtract the equation (3) and (4),

                            [tex]-35x+10y=25[/tex]

                              [tex]-6x+10y=10[/tex]

                ( - )

    [tex](-35x+6x)+(10y-10y)=(25-10)[/tex]

                                     [tex]-29x=15[/tex]

                                          [tex]x = - \frac{15}{29}[/tex]

                                          x = -0.517

          From the x value equation (2) becomes,

                     [tex]3(-0.517)-5y=-5[/tex]

Answer:

The original price was $43.50

Step-by-step explanation:

Let

x ----> the original price of a video game

we know that

1) The price of a video game increases by 20%

so

[tex]100\%+20\%=120\%=120/100=1.20[/tex]

The final price is equal to the original price multiplied by 1.20

so

[tex]1.20x[/tex]

2) The price of a video game decreases by 10%

so

[tex]100\%-10\%=90\%=90/100=0.90[/tex]

The final price is equal to the price at this moment multiplied by 0.90

so

[tex]0.90(1.20x)=1.08x[/tex]

we have that

[tex]1.08x=46.98[/tex]

solve for x

[tex]x=46.98/1.08\\x=\$43.50[/tex]

Answer:

Step-by-step explanation:

Step one) Figure our what peace of information you need to find and write down what information you already know.

•George weeded 1/5 of the garden.

•At the end 2/3 of the garden was left, which means that 1/3 of the garden was weeded.

•Now we need to figure out how much Summer weeded.

Step Two) Find the LCM (Lowest common multiple) of 5 and 3.

The LCM of 5 and 3 is 15.

Step three) Change the denominator of both problems to 15. Now the information you have should be:

•George weeded 3/15 of the garden. (We get the 3 on top because we multiplied 5 x 3 to get 15 so we multiply the numerator by 3 as well.)

•At the end there was 10/15 left. (We get the ten on top because the bottom was multiplied 3 x 5 to get 15, so then we take the numerator which is 2 and multiply that by 5 as well.)

•Now we know that if 10/15 weren’t picked that means that 5/15 were picked.

•We still need to figure out the amount that was picked by Summer.

Step 4)

Now we will use all the previous information to do the final step.

If a total of 5/15 were picked, and 3/15 of those were picked by George, then we do the problem:

5-3=2

Answer: Sally picked 2/15.

If you add 3 to x you have [tex]3+x[/tex]

Subtract this from 1: [tex]1-(3+x)=1-3-x=-2-x[/tex]

Double this: [tex]2(-2-x)=-4-2x[/tex]

The required answer is 4 + 2x.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

The given expression is,

Add 3 to x subtract the result from 1 then double

Convert it to the numerical expression,

Add 3 to x = 3 + x

subtract the result from 1 = 3 + x - 1

⇒ subtract the result from 1 = 2 + x

Now double of result  = 2(2 + x)

⇒ double of result  = 4 + 2x

this is the required solution.

Thus, the required answer is 4 + 2x.

Answer: The correct answer is D: 85 inches

Step-by-step explanation: The figure specified in the question is an equilateral triangle and one of it's properties is that all three sides have equal measurements.

The perimeter simply is a measurement of the lengths that runs around the entire shape. In other words the perimeter of a triangle is given as

Perimeter = 3L

Where L is the length of one side of the triangle.

If the perimeter of the table top is given as 255 inches, then we can now express it more properly as follows

255 = 3L

Divide both sides of the equation by 3

85 = L

Therefore the length of one side of the table measures 85 inches.

Answer:

k = 5

Step-by-step explanation:

Step 1:  Cross multiply

k/6 = 15/18

k(18) = 6(15)

18k = 90

Step 2:  Divide both sides by 18

18k / 18 = 90 / 18

k = 5

Answer:  k = 5

Another way to do it is to multiply both sides by 6

k/6 * 6 = 15/18 * 6

k = 90 / 18

k = 5

Answer: 5

Step-by-step explanation: To solve for k in the given proportion, we use the means-extremes property. The product of the extremes, (k)(18), equals the product of the means, (6)(15).

So we have (k)(18) or 18k = (6)(15) or 90.

Now we have the equation 18k = 90.

Dividing both sides by 18, k = 5.

It's a good idea to check the answer in these types of problems so if we plug a 5 back in for k in the original proportion, we have [tex]\frac{(5)}{6}= \frac{15}{18}[/tex] which is a true statement since 15/18 reduces to 5/6.
