Answer:

6 quarters and 2 pennies

Step-by-step explanation:

Let Q be the number of quarters that Bella has.

Let P be the number of pennies that Bella has.

We know that Bella has a total of 8 coins, so we can write:

Q + P = 8

We also know that Bella has a total of $1.52 in quarters and pennies. Since there are 100 pennies in a dollar, we can convert $1.52 to 152 pennies. We can then write another equation based on the value of the coins:

25Q + P = 152

Now we have two equations with two variables. We can solve for Q or P in terms of the other variable and substitute that expression into one of the equations to solve for the other variable. For example, we can solve the first equation for P:

P = 8 - Q

We can then substitute this expression for P into the second equation and simplify:

25Q + (8 - Q) = 152

24Q = 144

Q = 6

So Bella has 6 quarters. We can substitute this value for Q into the first equation and solve for P:

Q + P = 8

6 + P = 8

P = 2

So Bella has 2 pennies.

Therefore, Bella has 6 quarters and 2 pennies, for a total of 2 kinds of coins.

The distance between the point (5,12) and the line y = 5x + 12 is 4.90 units

If a point P with the coordinates (x₁, y₁), and we need to know its distance from the line represented by ax + by + c = 0

Then the distance of a point from the line is given by the formula:

d = (ax₁ + by₁ + c) / √(a² + b²)

Given: the point (5,12) and the line y = 5x + 12. The line can be written as

5x-y+12 = 0. Thus:

x₁ = 5, y₁ = 12, a = 5, b = -1, c = 12. Substitute these into the formula:

d = (ax₁ + by₁ + c) / √(a² + b²)

d = (5×5 + (-1×12) + 12) / √(5² + (-1)²)

d = 25/√26 = 4.90 units

Therefore, the distance between the point and the line is 4.90 units. Option D is the answer

Answer:

x = 5, y = 13

Step-by-step explanation:

Solve for x:
42 = 8x + 2

40 = 8x

x = 5

This is solved using the alternate interior angles theorem, which states that alternate interior angles (in this case, the 42-degrees and 8x + 2 degree angles) are the same.

Solve for y:

180 = 42 + 6(2y - 3)

180 = 42 + 12y - 18

180 = 24 + 12y

156 = 12y

y = 13

This is solved using the same-side interior angles theorem, which states that same-side interior angles (in this case, the 42-degrees and 6(2y-3)-degree angles) add up to 180 degrees.

Answer: V = 193.25π

Step-by-step explanation: The method to calculate volume of a solid of revolution is given by an integral of the form:

V =  \(\pi\int\limits^a_b {[f(x)]^{2}} \, dx\)

f(x) is the area is the function that rotated forms the solid.

For f(x)=y= \(\frac{5}{36}-x^{2}\) and solid delimited by x = 2 and x = 4:

V = \(\pi\int\limits^4_2 {(\frac{5}{36}-x^{2} )^{2}} \, dx\)

V = \(\pi\int\limits^4_2 {(\frac{25}{1296}-\frac{10x^{2}}{36}+x^{4}) } \, dx\)

V = \(\pi(\frac{25.4}{1296}-\frac{10.4^{3}}{108}+\frac{4^{5}}{5}-\frac{25.2}{1296}+\frac{10.2^{3}}{108}-\frac{2^{5}}{5} )\)

V = \(\pi(\frac{50}{1296}-\frac{560}{1296}+\frac{992}{1296} )\)

V = 193.25π

The volume of a solid formed by y = \(\frac{5}{36} - x^{2}\) and delimited by x = 2 and x = 4

is 193.25π cubic units.

Okay so you put -6 in where y is then solve and youll get your answer

Part B:

Mount Everest Great Himalayas of southern Asia 8,849.87 meters

In scientific notation

8.84987 * 10 ^3

Mount Olympus Mytikas, Greece 2,919.07 meters

In scientific notation

2.91907 * 10 ^3

Taking Everest and diving by Olympus

8.84987 * 10 ^3÷2.91907 * 10 ^3

8.84987/2.91907  * 10^(3-3) = 3.031742987

Part C:

The estimate is reasonable.  The estimate of 3 is very close to the value of 3.031742987   Therefore, we can conclude that the estimates for the heights were accurate.

Answer:

A) ≈3

B) ≈3

C) See below.

Step-by-step explanation:

Mount Everest is 8,849.87 meters tall.

Mount Olympus is 2,919.07 meters tall.

Part A:

Let's round each of the heights.

Mount Everest is 8,849.87 meters or approximately (I'm going to round to the nearest hundred) 8,800 meters.

Mount Olympus is 2,919.07 or approximately 2,900 meters.

Now, let's convert these numbers to scientific notation.

In order to convert a number to scientific notation, you would move the decimal to the left. Depending on how many spaces you move, you would then multiply the new number by 10 to the power of n.

Also, the new number must be between 1 and 10.

Mount Olympus is approximately 2,900.00 meters. To get a number between 1 and 10, we move the decimal place to the left three times. So:

\(O=2.91907\times 10^3\)

Since we moved three times, we multiply by 10 to the third:

\(O=2.9\times 10^3\)

Similarly for Mount Everest, it is approximately 8,800 meters. We are again going to move the decimal point to the left three times. So:

\(E=8.8\times 10^3\)

To find how many times Everest is taller than Olympus, divide the two, with Everest in the numerator:

\(\frac{8.8\times 10^3}{2.9\times 10^3}\)

The 10 cubed will cancel. So:

\(=\frac{8.8}{2.9}\)

Divide. Use a calculator:

\(\approx3\)

So, Everest is approximately three times as tall as Olympus.

Part B)

Now, do the same instead this time, we won't round.

Olympus:

\(O=2,919.07\)

Move decimal three times to the left:

\(O=2.91907\times 10^3\)

Same for Everest:

\(E=8,849.87\\E=8.84987\times 10^3\)

Again, divide them:

\(\frac{8.84987\times 10^3}{2.91907\times 10^3}\)

Time 10 cubed cancel. Use a calculator:

\(=\frac{8.84987}{2.91907}\approx3.031742987\approx3\)

Again, this is approximately 3.

Part C:

Yes, we can. The estimate we got (when rounding to the nearest hundred) is extremely close to the value we acquired when we didn't round (3.0317). Therefore, we can conclude that our estimate in Part A is reasonable.

Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20..

To estimate the value of the vehicle after 4 years, we can use the given equation A = 39500(0.86)^t, where A represents the value of the vehicle and t represents the number of years.

Substituting t = 4 into the equation:

A = 39500(0.86)^4

A ≈ 39500(0.5996)

A ≈ 23726.20

Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20.

This estimation is based on the assumption that the vehicle's value decreases by 14% each year. The equation A = 39500(0.86)^t models the exponential decay of the vehicle's value over time. By raising the decay factor of 0.86 to the power of 4, we account for the 4-year period. The final result suggests that the value of the vehicle would be around $23,726.20 after 4 years of ownership.

Answer:

20%

Step-by-step explanation:

The theoretical probability of drawing a red marble can be found by dividing the number of red marbles by the total number of marbles in the bag:

P(red) = number of red marbles / total number of marbles

P(red) = 5 / (5 + 8 + 12)

P(red) = 5 / 25

P(red) = 0.2

So the theoretical probability of randomly drawing a red marble is 20%, which corresponds to option (C).

The left-hand side of the equation represents the logarithm of 64 with base x, and it is not possible to find a real value of x that satisfies the equation.

solve the equation logₓ(64) + 5 = 2, we can follow these steps:

Step 1: Move the constant term to the other side of the equation:

logₓ(64) = 2 - 5

logₓ(64) = -3

Step 2: Rewrite the equation in exponential form:

x^(-3) = 64

Step 3: Rewrite 64 as a power of x:

x^(-3) = x^6

Step 4: Set the exponents equal to each other:

-3 = 6

The equation -3 = 6 is not true, which means there is no real solution to the given equation.

The height of the ramp above the ground is 10.1 inches.

Rajani wants to use a sheet of fibreboard 31 in long to create a skateboard ramp with a 19° angle of elevation from the ground.

The height of the ramp can be calculated as follows:

The situation forms a right angle triangle.

Using trigonometric ratios,

sin 19 = opposite / hypotenuse

where

opposite side = height of the ramp

hypotenuse = 31 inches

Therefore,

sin 19 = x / 31

The angle between the two sides of lengths a and b that maximizes the area of the triangle is θ = π/2.

The area of a triangle whose sides of lengths a and b with an angle θ between them is

A = 1/2ab sinθ

The given triangle has two sides of lengths a and b.

Consider θ is the angle between the a and b sides. Then the area of the triangle is

A = 1/2ab sinθ

For maximizing the area of the triangle, derivating the area we have and equate to zero i.e.,

dA/dθ = 0

⇒ dA/dθ = 1/2 ab cosθ = 0

⇒ cosθ = 0

∴ θ = π/2

And the condition for the maximum area is d²A/dθ² < 0.

I.e., d²A/dθ² = -1/2ab sinθ

⇒ d²A/dθ² = -1/2ab sin(π/2) = -1/2ab < 0

So, the maximum area is  

Δ(max) = 1/2 ab sin(π/2) = 1/2ab

Thus, the angle between the two sides of lengths a and b of a triangle is π/2 when its area is maximum.
