have a splendid day

Given the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days stretch is 55.5 miles.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here, we have,

Expression for the Total of Distance ran by Maria

Total distance = Distance ran each day × Number days

Given the data in the question;

Distance ran each day by Maria Dm = 3.7miles

Number days ran n = 15days

Total number of distance ran by Maria TDm = ?

Hence, Total distance = Distance ran each day × Number days

TDm = Dm × n

We substitute in our values

TDm = 3.7miles × 15

TDm = 55.5miles

Thus, the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days stretch is 55.5miles.

Answer:

So our answer in pi form is 30.25π

Step-by-step explanation:

The circumference of a circle is given by the formulas :

[tex]2\pi r[/tex] or [tex]\pi d[/tex]  where r is radius and d is the diameter

Since

11π = 2πr

We can solve for r to use it in the area of a circle formula:

[tex]\frac{11\pi }{2\pi } = r[/tex]

r = 5.5

The area of a circle is given by the formula:

[tex]\pi r^{2}[/tex] where r is the radius/.

Since we found r we can find the area:

π(5.5)² = 30.25π

So our answer in pi form is 30.25π

Answer:

As you have not specified the format in which to give the answer, I am giving three ways of writing it:

[tex]\sf 30.25 \pi \ units^2[/tex]

[tex]\sf \dfrac{121}{4} \pi \ units^2[/tex]

95.03 units² (nearest hundredth)

Step-by-step explanation:

Formulae

(where r is the radius)

Given:

Therefore, use the given value and the circumference equation to find the radius:

⇒ circumference = 11π

⇒ 2πr = 11π

⇒ 2r = 11

⇒ r = 5.5

Now we have found the radius, simply substitute this into the equation for area of circle:

⇒ area of a circle = πr²

                             = π5.5²

                             = 30.25π units²

Answer:

weight in an elevator must be less than 2000 lbs goes with w < 2000

a ton is 2000 lbs goes with w = 2000

the pool must hold at least 2000 gallons goes with w ≥ 2000

the scale can hold up to and including 2000 lbs goes with w ≤ 2000

my car weighs more than 2000 lbs goes with w > 2000

Step-by-step explanation:

If the weight is less than 2000 lbs, then the inequality will have a lesser than sign. The choice that matches is w < 2000.

If a ton is exactly 2000 lbs, then it's equal to 2000. In other words, the inequality will have an equal sign. The choice that matches is w = 2000.

If a pool should be held with at least 2000 lbs, then it's weight is either greater than or equal to 2000 lbs. the choice that matches is w ≥ 2000.

If a scaled can hold up to, including 2000lbs, then the maximum weight it can hold is 2000 lbs. The weight is less than or equal to 2000. the choice that matches is w ≤ 2000.

If a car weighs more than 2000 pounds, then the weight will be greater than 2000. The choice that matches is w > 2000.

Answer:

[tex]beinggreat78 ~is ~here ~to~ help~ you![/tex]

Let's start with 5 squared. 5 squared, or just squared in general, represents the number behind it times itself.

[tex]5^2~or~ 5*5 = 25[/tex]

Now, add 3

[tex]25 + 3 = 28[/tex]

Next, subtract 1

[tex]28 - 1 = 27[/tex]

Now, you must divide, because the line under the first equation represents division, or a fraction. For this case, division. Before dividing your result, 27, by y, the second equation, you first want to solve equation 2, y.

[tex]\frac{18}{2} = 9[/tex]

Lastly, divide x by y, 27 divided by 9

[tex]\frac{27}{9} = 3[/tex]

Answer:

L = 10 in
P = 40 in

Step-by-step explanation:

The area of a square is given by the equation:

A = L²

We rearrange this equation to make L the subject:

Square root both sides:

√A = L

Now we substitute A into our rearranged equation to find L:

L = √A

L = √100

L = 10 in

The perimeter of a square is given by the equation:

P = 4L

Substitute the L we just found to find P:

P = 4(10)

P = 40 in

The rate of lawn mowing is given as 4/3 lawns per hour.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

The given problem can be solved using unitary method as follows,

The number of lawns mowed in 9 hours = 12

Then, number of lawns mowed in 1 hour = 12/9 = 4/3.

Hence, the rate of mowing lawn for Audrey is 4/3 lawns per hour.

Answer:

C. √2 - 1

Step-by-step explanation:

If we draw a square from the center of the large circle to the center of one of the small circles, we can see that the sides of the square are equal to the radius of the small circle (see attached diagram)

Let r = the radius of the small circle

Using Pythagoras' Theorem [tex]a^2+b^2=c^2[/tex]

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

to find the diagonal of the square:

[tex]\implies r^2 + r^2 = c^2[/tex]

[tex]\implies 2r^2 = c^2[/tex]

[tex]\implies c=\sqrt{2r^2}[/tex]

So the diagonal of the square = [tex]\sqrt{2r^2}[/tex]

We are told that the radius of the large circle is 1:

⇒ Diagonal of square + r = 1

[tex]\implies \sqrt{2r^2}+r=1[/tex]

[tex]\implies \sqrt{2r^2}=1-r[/tex]

[tex]\implies 2r^2=(1-r)^2[/tex]

[tex]\implies 2r^2=1-2r+r^2[/tex]

[tex]\implies r^2+2r-1=0[/tex]

Using the quadratic formula to calculate r:

[tex]\implies r=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]\implies r=\dfrac{-2\pm\sqrt{2^2-4(1)(-1)}}{2(1)}[/tex]

[tex]\implies r=\dfrac{-2\pm\sqrt{8}}{2}[/tex]

[tex]\implies r=-1\pm\sqrt{2}[/tex]

As distance is positive, [tex]r=-1+\sqrt{2}=\sqrt{2}-1[/tex]  only
