To find the amount of the increase, calculate the difference in premiums per $1,000 between when Taylor Breen took out the policy at age 48 and when he will be 53 years old next year. The amount of the increase is $170.

To find the amount of the increase, we need to calculate the difference in premiums per $1,000 between when Taylor Breen took out the policy at age 48 and when he will be 53 years old next year.

First, let's calculate the initial premium per $1,000 at age 48:

$100,000 / $1,000 = 100  (number of units)

$100,000 * $4.70 = $470,000  (initial premium)

Next, let's calculate the premium per $1,000 when Taylor Breen will be 53 years old:

$100,000 / $1,000 = 100  (number of units)

$100,000 * $6.40 = $640,000  (premium at age 53)

The amount of the increase is:

$640,000 - $470,000 = $170,000

Therefore, the amount of the increase is $170.

Answer: No her plates will not fit in the box

Step-by-step explanation: Each plate is 0.5 inches tall; therefore, the stack of 8 plates will have a height of .

Also, the diameter of the largest plate is 10 inches or has a radius of 5 inches, which matches the radius of the cylindrical box; therefore, we know that the stack of plates can fit into the base area of the cylindrical box.

What we want to figure out now is the height of the cylindrical box to see if it is greater than or equal to 4 inches—the height of the stack of plates.

The volume of a cylinder is , and since for our cylindrical box the volume is 150 cubic inches; therefore,

putting in  and solving for height  we get

,

which is not greater than 4 inches, which means the plates will not fit into the box since the height of the stack is greater than the height of the box.

Answer:

18.5 ft (to the nearest tenth)

Step-by-step explanation:

The diameter of the circle passes through the center of the circle and divides the width of the circle into two equal parts.

We complete the circle and apply the Law of Intersecting Chords.

In the diagram, by this law:

AB X BC =DB X BE

7*x=14.5X14.5

x=14.5X14.5÷7

x=30.04

Therefore:

Length of the Diameter= 7+30.04 ft=37.04 ft

Radius =37.04/2= 18.5 ft

The radius of the circle should be 18.5 ft (to the nearest tenth).

Since there is the bridge is 7 ft tall and 29 ft wide.

Also,

here we apply the Law of Intersecting Chords.

So,

[tex]AB \times BC =DB \times BE\\\\7\times x=14.5\times 14.5\\\\x=14.5\times 14.5\div 7[/tex]

x=30.04

Now

Length of the Diameter= 7+30.04 ft=37.04 ft

So, Radius = 50% of 37.04 =  18.5 ft

Hence, The radius of the circle should be 18.5 ft (to the nearest tenth).

Step-by-step explanation:

I'm pretty sure it's asking for the circumference. The formula for finding the circumferene is C=πd (d=diameter) First, you need to fiind the diameter. Thequestion gives you the radius, 6.5, which is half the diameter. multiply that by 2 and you get 13. The question says to use 3.14 as π, so just multiply 3.14 by 13 and you get 40.82, which rounds to 41.

Final answer:

To solve the system of equations, use the method of elimination. Multiply the second equation by 4 to make the coefficients of 'x' in both equations opposite. Add the two equations together to eliminate 'x' and solve for 'y'. Substitute the value of 'y' into one of the original equations and solve for 'x'. The solution to the system of equations is x = -5/2 and y = -1.

Explanation:

To solve the system of equations:

4x + 9y = -19

-4x - 7y = 13

We can use the method of elimination. Multiply the second equation by 4 to make the coefficients of 'x' in both equations opposite:

16x + 28y = -52

Now, add the two equations together to eliminate 'x':

37y = -39

Divide both sides by 37:

y = -1

Substitute the value of 'y' into one of the original equations:

4x + 9(-1) = -19

4x - 9 = -19

Add 9 to both sides:

4x = -10

Divide both sides by 4:

x = -10/4 = -5/2

Therefore, the solution to the system of equations is x = -5/2 and y = -1.

Answer:

{-2/7, 2/7}

Step-by-step explanation:

Here you're being asked to solve the given equation 49w^2-4=0 for w with the hint that the solutions are fractions.

49w^2-4=0 is the product of the sum and difference of two squares:

(7w - 2)(7w + 2) = 0

Setting each factor equal to zero and solving for w, we get:

{-2/7, 2/7} as the solutions.

Answer:

B

Step-by-step explanation:

Given

3x² + 21x + 18 ← factor out 3 from each term

= 3(x² + 7x + 6) ← factor the quadratic

Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 7)

The factors are + 6 and + 1, since

6 × 1 = 6 and 6 + 1 = 7, thus

x² + 7x + 6 = (x + 6)(x + 1)

Thus

3x² + 21x + 18 = 3(x + 6)(x + 1) → B

Step-by-step explanation:

It appears that the "code" is that vowels count 2 and consonants count 1.

  GOLD = 1 for GLD +2 for O = 3+2 = 5

  LEAD = 1 for LD +2 for EA = 2 +4 = 6

  SILVER = 1 for SLVR +2 for IE = 4 +4 = 8

  URANIUM = 1 for RNM +2 for UAIU = 3 +8 = 11

  PLATINUM = 1 for PLTNM +2 for AIU = 5 +6 = 11

The missing number is PLATINUM =15

A sequence in mathematics is an enumerated collection of items in which repetitions are permitted and order is important.

Given that, GOLD = 5, LEAD = 6, SILVER = 8, URANIUM = 11, PLATINUM = ? from the given data we can see its in a sequence let say GOLD=5

so adding natural number (1, 2, 3, 4, ...) in the sequence will give next valueGOLD = 5LEAD = 5+1=6SILVER = 6+2=8URANIUM = 8+3=11

Step-by-step explanation:

The requried Rocco can wear his shirts with jeans in 10 different ways. The correct answer is 10.

To determine the number of different ways Rocco can wear his shirts with jeans, we need to multiply the number of options for shirts by the number of options for jeans. In this case, Rocco has 5 different shirts and 2 different pairs of jeans.

Since he can wear any shirt with any pair of jeans, the total number of different combinations is obtained by multiplying the number of shirts (5) by the number of jeans (2):

5 shirts * 2 pairs of jeans = 10 different ways

Therefore, Rocco can wear his shirts with jeans in 10 different ways. The correct answer is 10.

Answer: -1 is not in the domain and 0 and 2 are in the domain

Step-by-step explanation:

The domain of the function g(x) = “8x” is all real numbers, as there are no restrictions on the values that x can take.

The question seeks to find the domain of a function represented as g(x) = “8x. A function's domain refers to all the possible values that can be input into the function. In the case of g(x) = “8x, this is a linear function where x can take any real number value since there are no restrictions like square roots or denominators that could potentially exclude certain x values. Therefore, the domain of g is all real numbers, often represented as (-∞, +∞) or ℝ in set notation.
