Can someone help (it about arc length and area)

Answer:

x = 66

Step-by-step explanation:

For a set of N numbers:

{x₁, x₂, ..., xₙ}

The mean can be calculated as:

[tex]M = \frac{x_1 + x_2 + ...+ x_n}{N}[/tex]

In this case we have the data set:

{98, 122, 104, 115, 107, x}

And I assume that we want to have the mean = 102.

So we have a set of 6 numbers, the mean of this set will be:

[tex]M = \frac{98 +122+104+115+107+x}{6} = 102[/tex]

We need to solve this equation for x.

If we multiply both sides by 6, we get:

(98 + 122 + 104 + 115 + 107 + x) = 102*6 = 612

546 + x = 612

x = 612 - 546 = 66

x = 66

Step-by-step explanation:

The expression and the dimension of the prism are not given.

So, I will just give a general expression.

The volume of a prism is:

[tex]Volume = Length * Width * Height[/tex]

Assume that:

[tex]Length = 2[/tex]

[tex]Width = 2[/tex]

[tex]Height = 1\frac{2}{3}[/tex]

See attachment

Monica's expression should be:

[tex]Volume = 2 * 2 * 1\frac{2}{3}[/tex]

And the solution will be:

[tex]Volume = 2 * 2 * \frac{5}{3}[/tex]

[tex]Volume = \frac{20}{3}[/tex]

The statement which is true of the right triangles ABC and DEF is Area of ABC is greater than area of DEF.

Right angled triangle are those triangle for which one of the angle is 90 degrees.

Given two right angled triangles, ABC and DEF.

Area of a triangle = 1/2 × base × height

Area of ΔABC = 1/2 × 14 × 6

                        = 42 square units

Base of ΔDEF = √(7² + 4²) = √65

Height of ΔDEF = √(5² + 8²) = √89

Area of ΔDEF = 1/2 × √65 × √89

                       = 38.03 square units

Hence the correct option is Area of ABC is greater than area of DEF.

Answer:

m∠NSR = 113°

m∠RSP = 67°

Step-by-step explanation:

Angle formed between the intersecting chords is one half the sum of the measures of the arcs intercepted by the angles.

m∠NSR = [tex]\frac{1}{2}[\text{arc}(NR)+\text{arc}(PQ)][/tex]

             = [tex]\frac{1}{2}(176+50)[/tex]

             = 113°

Since, m∠NSR + m∠RSP = 180° [Linear pair of angles are supplementary]

113° + m∠RSP = 180°

m∠RSP = 180° - 113°

             = 67°

[tex]\frac{BE}{BA}[/tex] = [tex]\frac{BD}{BC}[/tex] , substitute values

[tex]\frac{BE}{21}[/tex] = [tex]\frac{3}{18}[/tex] ( cross- multiply )

Answer:

6 feet

Step-by-step explanation:

Given that,

The perimeter of the square, P = 24 feet

We need to find the side of the square.

The perimeter of a square is given by the formula as follows :

[tex]P=4a[/tex]

Where

a is the side length

So,

[tex]a=\dfrac{P}{4}\\\\a=\dfrac{24}{4}\\\\a=6\ feet[/tex]

So, the side of each log be 6 feet.

Answer:

A = 68

B = 44

C = 68

Step-by-step explanation:

find x:

68 + x + x - 24 = 180

2x + 44 = 180

180 - 44 = 136

136 / 2 = 68

x = 68

Answer:

the answer for this question is option c

a. To find the amount of the down payment, we need to multiply the price of the home by the percentage of the down payment required.

How would one define compounding?

Compounding is the method through which interest is added to both the principle balance already in place and the interest that has already been paid. Thus, compounding can be thought of as interest on interest, with the result that returns on interest are magnified over time, or the so-called "magic of compounding."

The price of the home is $456,500 and the down payment percentage is 20%, so:

Down payment = $456,500 x 20% = $456,500 x 0.20 = $91,300

b. To find the amount of the mortgage loan, we can subtract the down payment from the price of the home.

The price of the home is $456,500 and the down payment is $91,300 so:

Mortgage loan = $456,500 - $91,300 = $365,200

Therefore, the amount of the down payment is $91,300 and the amount of the mortgage loan is $365,200.

Answer:

the amount of force is zero newton

Step-by-step explanation:

Given that

Mass of an object = 2kg

Constant speed of the object = 8m/s

We need to find out the amount of the force

As in the question it is mentioned that the speed is constant so there would be no change in the velocity due to this acceleration would be zero

Now following formula should be used to find out the force

Force = ma

As a = 0

f = 0

Therefore, the amount of force is zero newton
