Answer:

C. $14,000

Step-by-step explanation:

If he is now being charged an annual premium of $720.90. The increase in his home's value is $14,000.

Increase in home value=[(720.90/0.27)-(683.10/0.27)]×$100

Increase in home value=(2670-2530)×$100

Increase in home value=140×$100

Increase in home value=$14,000

Therefore the increase in his home's value is $14,000.

Answer: [tex]\dfrac{25}{56}[/tex]

Step-by-step explanation:

Given: P(dot sent) = [tex]\dfrac37[/tex]

and P(dash sent) = [tex]\dfrac47[/tex]

P(dot received) = P(dot received ∩ dot sent)

+ P(dot received ∩ dash sent)

= P(dot received | dot sent)P(dot sent)  + P(dash received | dash sent)P(dash sent)   [By conditional probability formula]

[tex]=\dfrac78\times\dfrac37+\dfrac18\times\dfrac47=\dfrac{25}{56}[/tex]

Hence, the probability that the received symbol is a dot = [tex]\dfrac{25}{56}[/tex]

Answer:

2.25

Step-by-step explanation:

5.20 * 1.06 = 5.512

11.70 - 5.512 = 6.188

6.188 / 2.75 = 2.25018

Round to the nearest hundredth which equals....

Answer:

You have to convert 4 and 1/4 to 17/4. Then, the LCM of 3 and 4 is 12, so multiply 17/4 by 3/3 and 2/3 by 4/4 to get 51/12 and 8/12. Now, subtract.

51/12 - 8/12 = 43/12. That is the final answer.

Answer:

x = 16/15

Step-by-step explanation:

3x - 4 = 12

~Add 4 to both sides

3x = 16

~Divide 3 to both sides

x = 16/15

Answer:

9/12

Step-by-step explanation:

Just as the question says, you have to rewrite 3/4 with a denominator of 12, and you can do that by multiplying both the numerator (top) and denominator (bottom) by 3:

3/4 * 3 = 3(3)/4(3) = 9/12

Answer:

A = 3 and B = 2

Step-by-step explanation:

Here, we are interested in giving the values for A and B

We are told that there are three cartons, with 100 gun balls in each.

The total number of gum balls Jackson have will be 100 + 100 + 100= 300

Now, we want to express 300 in the form a•10^b

Thus;

300 = 3 * 100

3 * 100 = 3 * 10^2

where A = 3 and B = 2

35.60744985673352

= 35.61(2d.p)

Explanation:

When you divide it you get 35.60744985673352

To leave it in to 2 decimal place, you are to consider the the third number after the point which in this case is 7. So you check if it is greater than or equal to or less than 5. If it is greater than or equal to 5 you carry forward 1 to the next digit to the left which is 0 in this case which will give you 1, then you retrieve the number plus the first two decimals after the point to get 35.61(2d.p).

Step-by-step explanation:

The set of three numbers could be the side lengths of a right triangle is to be considered as the option d. 14,48,50.

It is a theorem that should be attributed to Pythagoras where the square of the hypotenuse of a right triangle is equivalent to the sum of the squares of the other two sides.

So based on this we can say that

[tex]50^2 = 48^2 + 14^2\\\\[/tex]

2500 = 2,304 + 196

2,500 = 2,500

Hence, the option d is correct.

Answer:

a = - c

Step-by-step explanation:

2a - 2c = 4a

- 4a         - 4a

- 2a - 2c = 0

+ 2c        + 2c

- 2a = 2c

/-2      /-2

a = - c

Answer:

[tex]\boxed {a = -c}[/tex]

Step-by-step explanation:

Solve for the value of [tex]a[/tex]:

[tex]2a - 2c = 4a[/tex]

-Take [tex]4a[/tex] and subtract it from [tex]2a[/tex]:

[tex]2a - 2c - 4a = 4a - 4a[/tex]

[tex]-2a - 2c = 0[/tex]

-Add both sides by [tex]2c[/tex]:

[tex]-2a - 2c + 2c = + 2c[/tex]

[tex]-2a = 2c[/tex]

-Divide both sides by [tex]-2[/tex] and dividing [tex]-2[/tex] undoes the multiplication by [tex]-2[/tex]:

[tex]\frac{-2a}{-2} = \frac{-2c}{-2}[/tex]

[tex]\boxed {a = -c}[/tex]

Therefore, the value of [tex]a[/tex] is [tex]-c[/tex].

The polygon has 5 sides. A polygon with 5 sides is a

pentagon.

If you draw the line containing the side  it will

contain some points in the interior of the polygon. So,

the polygon is concave. Since it is concave, it is

irregular.

Scientific notation is a way of writing really big or really small numbers that take a lot of work to write out fully. Scientific notation is used because it's tiring to write out the numbers, which are usually very long. It's a way to shorten them while still knowing what the original number is.

Answer:

[tex]\frac{4}{5}[/tex]

Step-by-step explanation:

let the original fraction be

[tex]\frac{n}{n+1}[/tex] ( with denominator 1 more than numerator )

Subtracting 3 from numerator/ denominator gives

[tex]\frac{n-3}{n+1-3}[/tex] = [tex]\frac{n-3}{n-2}[/tex]

Given that the fraction is now equivalent to [tex]\frac{1}{2}[/tex] , then

[tex]\frac{n-3}{n-2}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2(n - 3) = n - 2, distribute left side

2n - 6 = n - 2 ( subtract n from both sides )

n - 6 = - 2 ( add 6 to both sides )

n = 4

and n + 1 = 4 + 1 = 5

Thus original fraction is [tex]\frac{4}{5}[/tex]

I used a regression calculator for the first one.

I multiplied 15.109 and 4 because t is the time.

add 56.4

Answer:

[tex] \huge \: t = \frac{13}{2} [/tex]

Step-by-step explanation:

[tex]10t - 5 = 60[/tex]

Using the addition property add 5 to both sides of the equation

That's

[tex]10t - 5 + 5 = 60 + 5 \\ 10t = 65[/tex]

Divide both sides by 10

[tex] \frac{10t}{10} = \frac{65}{10} \\ t = \frac{65}{10} [/tex]

Reduce the fraction with 5

We have the final answer as

[tex]t = \frac{13}{2} \\ [/tex]
