ages together it
would be 66. Her grandmouer
is ten times older than Ginger.
What are the ages of each
person?

Answers

Answer:

Step-by-step explanation:

Let us consider the Ginger to be x years old.

Therefore, her grandmother will be 10x years old(10 times Ginger's age)

So,

10x+x=66

(adding both Ginger and her grandmother's age)

11x=66

(adding x and 10x)

x=66/11

x=6

Ginger's age is 6.

Her grandmother is 10 times her age.

How to Find the Value of a Variable in an Equation?

Finding the value of a variable in an equation involves solving the equation for that variable. This process typically involves several steps, including isolating the variable on one side of the equation, using inverse operations to simplify the expression, and substituting known values into the equation to find the value of the variable.

Therefore:

a. 2/5t = 6

Multiply both sides by 5/2:

t = 6 * 5/2

t = 15

b. -4.5 = a - 8

Add 8 to both sides:

-4.5 + 8 = a

12.5 = a

a =12.5

c. 1/2 + p = 3

p = 3 - 1/2

p = 5/2

Round your answer to the nearest cent.​

Answers

In 3 years, Aubrey will be able to spend $106.08 on a new bicycle.

To find out how much Aubrey will be able to spend on the bike in 3 years

First we can use the formula for compound interest:

A = P * (1 + r/n)^(nt)

Where:

A = final amount (balance)

P = principal (starting amount) = $100.00

r = interest rate as a decimal = 2% = 0.02

n = number of times per year that the interest is compounded = 1 (annually)

t = time in years = 3

Plugging in these values, we get:

A = $100.00 * (1 + 0.02/1)^(1 * 3)

A = $100.00 * (1.02)^3

A = $100.00 * 1.0608

A = $106.08

Therefore, in 3 years, Aubrey will be able to spend $106.08 on a new bicycle.

The flat rate for your service runs $9.50 per hour. To cover costs, you charge the flat rate plus 15% of that rate for the first 8 hours, and 10% of that rate on the second 8 hours. You estimate that a particular job will take 16 hours. Write the equations and the total estimate.

Answers

(9.50 + 0.15 x 9.50) x Hours  and  (9.50 + 0.10 x 9.50) x Hours are the equation to and the total  cost estimate is $173.04.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

For the first 8 hours: The flat rate is $9.50 per hour, so 15% of that rate is 0.15 x 9.50 = $1.43.

The cost for the first 8 hours is (9.50 + 1.43) x 8 = $96.64.

For the next 8 hours: The flat rate is still $9.50 per hour, so 10% of that rate is 0.10 x 9.50 = $0.95.

The cost for the next 8 hours is (9.50 + 0.95) x 8 = $76.40.

Total cost estimate = $96.64 + $76.40 = $173.04

We can also write the equations for the costs as follows:

For the first 8 hours: Cost = (9.50 + 0.15 x 9.50) x Hours = 1.15 x 9.50 x Hours

For the next 8 hours: Cost = (9.50 + 0.10 x 9.50) x Hours = 1.10 x 9.50 x Hours

Using these equations, we can calculate the cost for any number of hours up to 16.

Hence, (9.50 + 0.15 x 9.50) x Hours  and  (9.50 + 0.10 x 9.50) x Hours are the equation to and the total  cost estimate is $173.04.

Events A and B are independent, P(A)=P(B) and P(A∪B)=0.63 . Find P(B) .

Answers

Answer:

the probability of event B is approximately 0.48.

Step-by-step explanation:

P(A) = P(B) (given)

P(A∪B) = P(A) + P(B) - P(A∩B) (probability rule for the union of two events)

Since events A and B are independent, we know that P(A∩B) = P(A) × P(B).

Substituting the given values, we get:

0.63 = P(A) + P(B) - P(A) × P(B)

Since P(A) = P(B), we can substitute P(B) for P(A):

0.63 = 2P(B) - P(B)^2

Rearranging this equation, we get:

P(B)^2 - 2P(B) + 0.63 = 0

This is a quadratic equation that we can solve using the quadratic formula:

P(B) = [2 ± sqrt(4 - 4×0.63)] / 2

P(B) = [2 ± sqrt(1.48)] / 2

P(B) ≈ 1 or P(B) ≈ 0.48

Since probabilities must be between 0 and 1, we can discard the solution P(B) = 1, and the only possible solution is:

P(B) ≈ 0.48

Therefore, the probability of event B is approximately 0.48.

The solution set for the given inequality is {6, 7, 8, 9, 10,.....}.

What are inequalities?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality is -1/2(8x-32)< -4

Multiply by -2 on both the sides of an inequality, we get

(8x-32)>8

Add 32 on both the sides of an inequality, we get

8x>40

Divide 8 on both the sides of an inequality, we get

A restaurant has an aquarium in the shape of a rectangular prism. The base is 6 feet by 2. 5 feet in size. The height is 4 feet. How many square feet of glass was used in making this aquarium? ***hint---where is the glass part of the aquarium?***.

Answers

45 square feet of glass was used in making this aquarium.

A region's size on a surface is determined by its area. The term "surface area" refers to the area of an open surface or the perimeter of a three-dimensional object, whereas "plane area" refers to the area of a shape or planar lamina.

The base of the aquarium is 6 feet by 2.5 feet, so its area is 6 x 2.5 = 15 square feet.

Since the aquarium is a rectangular prism, it has three sides that are the same size as the base. So, each of the three sides has an area of 15 square feet.

Therefore, the total area of glass used in making the aquarium is 3 x 15 = 45 square feet.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

Let x represent the cost of renting one chair.

Let y represent the cost of renting one table.

The total cost to rent 3 chairs and 5 tables is $48. This means that

3x + 5y = 48 - - - - - - - - - -1

The total cost to rent 6 chairs and 2 tables is $30. This means that

6x + 2y = 30 - - - - - - - - - -2

Multiplying equation 1 by 6 and equation equation 2 by 3, it becomes

18x + 30y = 288

18x + 6y = 90

Subtracting, it becomes

24y = 198

y = 198/24 = 8.25

Substituting y = 8.25 into equation 1, it becomes

3x + 5 × 8.25 = 48

3x + 41.25 = 48

3x = 48 - 41.25

The derivative of y = sin(x)cos(x) is 2sin(x)cos(x).Using the formula above, we can calculate that: (sin(x)cos(x))' = cos(x)sin(x) + sin(x)cos(x) = sin(x)cos(x) + sin(x)cos(x) = 2sin(x)cos(x)

The rule for derivatives of trigonometric functions states that the derivative of a trigonometric function is the product of the coefficient and the derivative of the other function in the product. This rule can be expressed mathematically using the following formula: (f(x)g(x))' = f'(x)g(x) + f(x)g'(x) For example, let's say that we want to calculate the derivative of the function y = sin(x)cos(x). Using the formula above, we can calculate that: (sin(x)cos(x))' = cos(x)sin(x) + sin(x)cos(x) = sin(x)cos(x) + sin(x)cos(x) = 2sin(x)cos(x) Therefore, the derivative of y = sin(x)cos(x) is 2sin(x)cos(x).

The area of a square is one third the area of a triangle. If the base of the triangle and a side of the square are equal, what is the ratio of the height of the triangle to the side of the square ?.

Answers

The ratio of the height of the triangle to the side of the square is 6.

A triangle is a three-sided polygon with three vertices and three angles. Triangles can have different shapes and sizes, including equilateral, isosceles, and scalene triangles.

Let's call the side of the square x. Since the base of the triangle is equal to the side of the square, we can use x for both. The area of the square can then be found by x² and the area of the triangle can be found by (x)(h)/2, where h is the height of the triangle.

We know that the area of the square is one-third the area of the triangle, so we can set up an equation:

x² = (1/3)(x)(h)/2

Expanding the right side of the equation:

x² = (1/3)(xh)/2

Now we can isolate the height of the triangle by multiplying both sides by 6 and dividing by x:

6x² = (xh)

Finally, we can divide both sides by x to find the ratio of the height of the triangle to the side of the square:

6x = h

You invest $500 in an account that has an annual interest rate of 8% compounded weekly for 12 years what is the equivalent interest-rate and how many times will money be compounded how much will you have?

Answers

To find the equivalent interest rate and the number of times the money will be compounded, we need to use the formula for compound interest:

A = P(1 + r/n)^(nt)

where A is the amount of money at the end of the investment period, P is the initial investment, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the investment period in years.

In this case, P = $500, r = 8%, n = 52 (since the interest is compounded weekly), and t = 12 years. We can plug these values into the formula and solve for A:

A = $500(1 + 0.08/52)^(52*12) ≈ $1,333.30

So after 12 years, the investment will be worth approximately $1,333.30.

To find the equivalent interest rate, we can use the formula:

(1 + i) = (1 + r/n)^n

where i is the equivalent interest rate. Plugging in the values, we get:

(1 + i) = (1 + 0.08/52)^52
(1 + i) ≈ 1.0838
i ≈ 0.0838 or 8.38%

So the equivalent interest rate is approximately 8.38% and the money will be compounded 52 times per year (weekly).

Measure of angle V is 103°.

What is Polygons?

Polygons are closed figures which has at least three set of line segments joined together.

The polygon with least number of sides is triangle.

Here is a six sided polygon, which is hexagon.

Sum of interior angles of a polygon = (n - 2) 180, where n is the number of sides of the polygon.

Sum of the interior angles of the given polygon = (6 - 2) 180 = 720

So,

∠S + ∠T + ∠U + ∠V + ∠W + ∠X = 720°

90° + (9x - 19)° + 111° + (5x + 8)° + 128° + (7x + 3)° = 720°

9x + 5x + 7x + 90 - 19 + 111 + 8 + 128 + 3 = 720

21x + 321 = 720

21x = 399

What is the solution to the system of equation?

Given the system of equation in the question;

y = x + 12

y = (1/2)x

To solve the system of equation, first plug equation to into equation one and solve for x.

y = x + 12

Plug in y = (1/2)x

(1/2)x = x + 12

Multiply each term by 2

2(1/2)x = 2x + 2(12)

x = 2x + 24

x - 2x = 2x - 2x + 24

x - 2x = 24

-x = 24

x = -24

Now, plug x = -24 into equation two and solve for y.

y = (1/2)x

Plug in x = -24

y = (1/2)( -24 )

y = -24/2

y = -12
