Answer:

Option A. The ratio of the area to the circumference is equal to half the radius

Step-by-step explanation:

we know that

The area of a circle is equal to

[tex]A=\pi r^{2}[/tex]

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

The ratio of the area to the circumference is equal to

[tex]\frac{A}{C}=\frac{\pi r^{2}}{2\pi r}[/tex]

Simplify

[tex]\frac{A}{C}=\frac{r}{2}[/tex]

Verify

In this problem

[tex]A=153.86\ units^{2}[/tex]

[tex]C=43.96\ units[/tex]

[tex]\frac{A}{C}=\frac{153.86}{43.96}=3.5\ units[/tex]

and [tex]3.5\ units[/tex] is equal to half the radius

therefore

The ratio of the area to the circumference is equal to half the radius

Answer:

A: The ratio of area of circle to the circumference is equal to half the radius.

Step-by-step explanation:

We are given that area of a circle=153.86 square units

Circumference of circle=43.96 units

Radius of circle=7 units

We have to find that the relation ship between area of circle and circumference of circle

Area of circle=[tex]\pi r^2[/tex]

Circumference of circle=[tex]2\pi r[/tex]

Ratio of area of circle to the circumference=[tex]\frac{\pi r^2}{2\pi r}[/tex]

Ratio of area of the circle to the circumference of the circumference=[tex]\frac{1}{2} r[/tex]

Ratio of area to the circumference=[tex]\frac{153.86}{43.96}=\frac{7}{2}=\frac{r}{2}[/tex]

Hence, option A is true.

Answer:A: The ratio of area of circle to the circumference is equal to half the radius.

Final answer:

You should prepare a separate sheet with 3-5 references when an employer requests them, choosing them strategically and ensuring they agree to vouch for you.

Explanation:

When an employer asks for your list of references, you should be prepared to provide a separate sheet with this information, rather than listing it directly on your résumé. A generally accepted number of references is three, so the best answer to how many references should be ready to list if an employer asks for them is 3-5. These references could include a mix of superiors, co-workers, clients, or instructors. It is important to contact each reference to confirm their willingness to speak on your behalf and to ensure your reference sheet is consistent with the look of your cover letter and résumé. Moreover, always choose references strategically, selecting those who can positively attest to your skills, knowledge, and work habits.

After 10 years, the two siblings are 12 years and 36 years old.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

A father who is 42 years old has a son and a daughter.

The daughter is three times as old as the son.

Let x be the age of the son, then 3x be the age of the daughter.

After 10 years, the sum of all their ages will be 100 years.

That means,

x + 10 + 3x + 10 + 42 = 100

4x = 48

x = 12

Then 3x = 36.

Therefore, the ages of the siblings are 12 and 36.

Answer: D. Taking Art class and taking French class are not independent events because P(A|B)≠P(A) and P(B|A)≠P(B) .

Step-by-step explanation:

We know that for dependent events A and B , the conditional probability of getting a given that B is given by :-

[tex]P(A|B)=\dfrac{P(A\cap B)}{P(B)}[/tex]

From the given table, if A represent taking French class and B represent taking Art class.

Then P(A)=0.6

and P(B)=0.55

[tex]P(\cap B)=0.2[/tex]

Now, [tex]P(A|B)=\dfrac{0.2}{0.55}=0.036363\approx0.036[/tex]

[tex]P(B|A)=\dfrac{P(A\cap B)}{P(A)}=\dfrac{0.2}{0.6}=0.33333\aprox0.333[/tex]

Clearly, [tex]P(A|B)\neq P(A)[/tex]

[tex]P(B|A)\neq P(B)[/tex]

Therefore taking Art class and taking French class are not independent events because P(A|B)≠P(A) and P(B|A)≠P(B) .[ By definition of independent events]

The correct statement is D; Taking Art class and taking French class are not independent events.

Consider A represent taking a French class and B represents taking an Art class.

The formula to determine whether two events are independent or not is P(A and B) = P(A) x P(B),

where P(A and B) is the probability of both events happening together, P(A) is the probability of event A happening, and P(B) is the probability of event B happening.

D. Taking Art class and taking French class are not independent events because P(A|B)≠P(A) and P(B|A)≠P(B).

This statement is incorrect because the formula to determine whether two events are independent or not is;

P(A and B) = P(A) x P(B),

not P(A|B) ≠ P(A) and P(B|A) ≠ P(B).

Using the values in the table:

P(A) = 0.6 (taking French class)

P(B) = 0.55 (taking Art class)

P(A and B) = 0.2 (taking both classes)

P(A and B) ≠ P(A) x P(B)

0.2 ≠ 0.6 x 0.55

Step-by-step explanation:

If the radius of a circle is doubled, the area of the circle will be quadrupled and the circumference will also be doubled. This makes sense because the area of a circle is directly proportional to the square of the radius of the circle (if the radius of a circle is increased x times, its area will be increased to x^2 times the original area), whereas the circumference is proportional to the size of the radius (if the radius of a circle is increased x times, its circumference will increase x times).

The expression 4(2x+1)-(-6x) simplifies to the equivalent expression 14x + 4 using the distributive property and the rule for subtracting negative numbers.

The expression given is 4(2x+1)-(-6x). To simplify this expression, we should use the distributive property and also the rule that subtracting a negative is the same as adding a positive.

Let's break down the steps:

The equivalent expression for the given problem is found to be 14x + 4.

Final answer:

To find the speed of the current, we can set up equations for the boat's downstream and upstream speeds and solve for the current speed.

Explanation:

To find the speed of the current, let's assume the speed of the boat in still water is x mph. Since the boat's speed downstream is 60 mph, we can set up the equation:

(x + c) * t = 60

Where 'c' represents the speed of the current, and 't' represents the time taken. Similarly, the equation for the upstream speed of the boat (36 mph) can be written as:

(x - c) * t = 36

Simplifying these equations, we get:

x + c = 60/t

x - c = 36/t

Adding these equations, we obtain:

2x = 96/t

Solving for x, we get:

x = 48/t

Substituting this value back into one of the original equations, we can solve for t:

(48/t) + c = 60/t

Simplifying, we find:

c = 12/t

Therefore, the speed of the current is inversely proportional to the time taken for the downstream and upstream journeys.

c= 116.62ft

Step-by-step explanation:

The length of the diagonal of the football field is 116.62 yards.

The Pythagorean theorem states that in a right-angled triangle, the sum of the squares of the two smaller sides is equal to the square of the hypotenuse.

A football field is rectangular in shape.

The diagonal of a rectangle divides it into two right-angled triangles.

Therefore, the diagonal becomes the hypotenuse of the right-angled triangles.

Therefore, diagonal² = length² + width²

⇒ diagonal² = 10,000 + 3600 yards²

⇒ diagonal² = 13,600 yards²

⇒ diagonal = 116.62 yards

Therefore, the length of the diagonal of the football field is 116.62 yards.

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

7x-3 + 12x-7 = 180

Combine like terms

19x-10 = 180

Add 10 to each side

19x-10+10 = 180+10

19x = 190

Divide by 19

19x/19 = 190/19

x= 10

Answer:

10

Step-by-step explanation:

We are given a diagram which we are to analyze and and solve for x.

We can see the a straight line is intersected by another line thus forming two angles which are supplementary. It means that the sum of these angles is equal to 180 degree.

So we can write them as:

[tex] ( 7 x - 3 ) + ( 12 x - 7 ) = 180 \\\\ 12 x + 7 x = 180 + 3 + 7 \\\\ 19 x = 190 \\\\ x = \frac { 190 } { 19 }\\\\ x = 10 [/tex]

Therefore, the correct answer option is 10.
