Answer:

153.9

Step-by-step explanation:

Formula for area

A = r^2 * π

A = 7^2 * π

A = 153.93804

A ≈ 153.9

Answer:

113.04

Hope this helps!

Answer:

113.04

Step-by-step explanation:

So in order to get area you gotta do R times R times Pie

So then,

You do 6 times 6,

and get 36,

Then you times 36 by 3.14 estimated,

Which gets you 113.04

The system of inequalities is y<x  and y<4.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other.

To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given, the region is shaded y < 4.

And the region is not exceeding the x.

So, y<x.

Therefore, the system of inequalities is y<x  and y<4.

Step-by-step explanation:

Answer:

Hello There the Correct answer is 20% start off by finding 10% of $14. in order to find 10%, divide it by 70 which gives 2. you now need to make the 30% to add to the 70%, by timesing the 2 by 3to give 6. now all you need to do it add the 6 to 14 to make 20!

so your answer is $20

The question is missing the sample life insurance premium illustration  as found in the attached.

The correct option based on the below calculation is A,$33.75

Step-by-step explanation:

A female non-smoker  who wanted a coverage of $25,000 as found in attached the sample life insurance premium illustration would pay $6.75 in premium.

Based on the above, a female non-smoker who wanted a coverage of $125,000 has it premium computed thus:

premium=$125,000/$25,000*$6.75

premium=5*$6.75=$33.75

The correct option is A,$33.75

Answer:

The insurance premium for a 42-year old nonsmoking female who wants $125,000 in coverage is $33.75. The right answer is a.

Step-by-step explanation:

In order to calculate the insurance premium for a 42-year old nonsmoking female who wants $125,000 in coverage we would have to use the following formula:

insurance premium= (coverage amount/monthly premiun amount)*$6.75

Therefore, insurance premium= ($125,000/$25,000)×$6.75

insurance premium= $33.75

The insurance premium for a 42-year old nonsmoking female who wants $125,000 in coverage is $33.75

Answer:To find the volume of a composite solid, u identify the different parts it is made of, work out the volume of each part independently, and sum up the volumes of its parts. For composite prisms, where the bases are a composite shape, the area of the bases is the sum of the areas of the parts it is made of.

We have been given that last month Maria purchased a new cell phone for $500. The store manager told her that her cell phone would depreciate by 70% every 6 months.

We know that an exponential function is in form [tex]y=a\cdot (1-r)^x[/tex], where,

y = Final value,

a = Initial value,

r = Decay rate in decimal form,

x = Time in years.

Let us convert [tex]70\%[/tex] into decimal form.

[tex]70\%=\frac{70}{100}=0.70[/tex]

Initial value of car is 500, so [tex]a=500[/tex].

Since value of phone depreciates every  months, so value of phone will depreciate twice in a year.

Upon substituting our given values in exponential decay function, we will get:

[tex]V=500(1-0.70)^{2x}[/tex]

To find the value of phone after 2 years, we will substitute [tex]x=2[/tex] in our equation.

[tex]V=500(1-0.70)^{2(\cdot 2)}[/tex]

[tex]V=500(1-0.70)^{4}[/tex]

Therefore, option D is the correct choice.

Let us simplify our equation.

[tex]V=500(0.30)^{4}[/tex]

Therefore, option B is correct as well.

Answer:

Regression to the mean occurs when the next generation regresses to the overall mean of the population.

Step-by-step explanation:

Regression to the mean occurs when the next generation regresses to the overall mean of the population. Extreme traits trend back to the average and are not increased or decreased in terms of measure. Measurable traits or characteristics that are extreme move back toward the average value. The next generation traits move back, or regress, to the average of that trait

Answer:

Regression to the mean is a statistical phenomenon that occurs whenever you have a nonrandom sample from a population and two measures that are imperfectly correlated.

Answer:

The Triangle Is A Right Triangle Because 5^2 + 12^2 = 13^2.

Step-by-step explanation:

5^2 = 25. 12^2 = 144. With the Pythagorean theorem, (a^2 + b^2 = c^2), 5 is a, 12 is b, and 13 is c.

25 + 144 = 169.

13 ^ 2 = 169.

Since a^2 + b^2 = c^2 is true, the triangle is a right triangle.

Given:

Sides of triangle= 5cm, 13cm and 12cm

To find: Whether a triangle is a right angled triangle.

This can be solved by applying Pythagorean theorem:

According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

[tex]H^2=P^2+B^2[/tex]

where,

H= Hypotenuse

P= Perpendicular

B=Base

Applying given values in the formula:

[tex]H^2=P^2+B^2\\\\13^2=5^2+12^2\\\\169=25+144\\\\169=169[/tex]

Since, R.H.S= L.H.S

Thus, we can say that this triangle is a right angled triangle.

Answer:

WRS=25 degree

Step-by-step explanation:

Angle VRT + angle TRS = 180 degree (supplementary angles)

5x+25x+30=180

5x+25x=180-30

30x=150

x=150/30=5

Substituting x=5 into angle VRT

5(5)=25

VRT= 25 degree

Looking at the diagram, angle VRT and angle WRS are vertically opposite angle and are therefore equal.

Now, angle WRS= 25 degree

The measure of the angle of intersecting lines ∠WRS = 25°

Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.

Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.

When lines intersect, two angle relationships are formed:

Opposite angles are congruent

Adjacent angles are supplementary

Given data ,

Let the two intersecting lines be a and b

where the measure of ∠SRT = ( 25x + 30 )°

The measure of angle ∠VRT = ( 5x )°

And , the measure of ∠VRT = measure of ∠WRS ( Opposite angles are congruent )

And , the measure of ∠VRT + measure of ∠SRT = 180° ( angles in straight line )

So , 5x + 25x + 30 = 180

30x = 150°

Divide by 30 on both sides , we get

x = 5

Now , the measure of ∠WRS = [ 5 ( 5 ) ] °

Hence , the measure of angle ∠WRS = 25°

Answer:

Adult tickets cost $11 and child tickets cost $13

Step-by-step explanation:

Multiply the second equation by -2, then add the equations together.

(8a+9c=205)

−2(4a+3c=83)

Becomes:

8a+9c=205

−8a−6c=−166

Add these equations to eliminate a:

3c = 39

Then solve3c=39for c:

3c=39

[tex]\frac{3c}{3}[/tex] = [tex]\frac{39}{3}[/tex]

(Divide both sides by 3)

c = 13

Now that we've found c let's plug it back in to solve for a.

Write down an original equation:

8a+9c=205

Substitute 13 for c in 8a+9c=205:

8a+(9)(13)=205

8a+117=205 (Simplify both sides of the equation)

8a+117+−117=205+−117 (Add -117 to both sides)

8a=88

[tex]\frac{8a}{8}[/tex] = [tex]\frac{88}{8}[/tex]

(Divide both sides by 8)

a = 11
