Answer:

1 quarter, 1 dime, and 4 nickels

Step-by-step explanation:

First you subtract the 18 cents that were found in the pocket from the total amount of 73 cents to get the total amount of the 6 other coins:

73-18=55.

So the total amount of the 6 coins equals 55 cents.

The quarter = 25 cents

The dime = 10 cents

The 4 nickels =  5 + 5 + 5 + 5 = 20

1 quarter, 1 dime, and 4 nickels add up to the necessary total of 6 coins and when you add up the total cents of the quarter, dime, and nickels, 25 + 10 + 20 it comes to the sum of 55, which is how much the 6 coins are worth in total.

So therefore, the answer is 1 quarter, 1 dime, and 4 nickels.

Answer:

Do you have a pic of the pie chart, or can you type in the percentages?

Step-by-step explanation:

Answer:

3300 was on 3% and 6700 on 2,5%

Step-by-step explanation:

We can say that 'a' represents the price that will go on 3% interest and 'b' 2,5% interest.

Therefore;

a + b = 10 000

And

0,03a + 0,025b = 283.5 (0,03 means 3% etc)

You can move 'b' to the other side to leave 'a' on the LHS

0,03a = 283.5 - 0,025b - - > (divide both sides by 0,03)

a=9450 - 0,8333b

Substitute this equation as 'a' in the first equation to get:

9450 - 0,8333b + b = 10 000 (move 9450 to the RHS to leave values with b on the LHS)

-0,8333b + b = 10 000 - 9450

0,1666b = 550 (divide both sides by 0,1666)

b = 3,300

Therefore 'a' will be :

a= 10 000 - 3 300

a = 6700

I hope this helps.

After solving the system of equations, the amount in the account with 3% interest was $844.50 and the amount in the account with 2.5% interest was $9155.50 after one year.

Let's assume the amount invested at 3% interest is x and the amount invested at 2.5% interest is y. We can set up the following system of equations:

x + y = 10000 (equation 1)

0.03x + 0.025y = 283.50 (equation 2)

Multiply equation 1 by 0.03 and equation 2 by 100 to eliminate decimals:

0.03x + 0.03y = 300 (equation 3)

3x + 2.5y = 28350 (equation 4)

Now, subtract equation 3 from equation 4:

3x + 2.5y - 0.03x - 0.03y = 28350 - 300

Simplify:

2.97x + 2.47y = 28050 (equation 5)

Multiply equation 1 by 2.47 and equation 2 by -2.97 to eliminate y:

2.47x + 2.47y = 24700 (equation 6)

-2.97x - 2.97y = -842.25 (equation 7)

Add equation 6 and equation 7:

2.47x + 2.47y - 2.97x - 2.97y = 24700 - 842.25

Simplify:

-0.5x = -422.25

Divide both sides by -0.5:

x = 844.50

Substitute the value of x back into equation 1:

844.50 + y = 10000

Subtract 844.50 from both sides:

y = 9155.50

Therefore, there was $844.50 in the account with 3% interest and $9155.50 in the account with 2.5% interest after one year passed.

Using trigonometric ratios, the length in inches of the given triangle is 22 inches.

Given a right angled triangle.

The length of the hypotenuse is also given.

We can find the length of "a" using the sine trigonometric ratio.

We know that,

Sine of any angle is defined as the ratio of the opposite side to the hypotenuse of a right angled triangle.

Using the sine function here for the angle 30°,

sin (30°) = opposite side / adjacent side

sin (30°) = a / 44

Or,

a / 44 = sin (30°)

We know that sin (30°) = 1/2.

So,

a / 44 = 1/2

Multiplying both sides by 44, we get,

a = 44 / 2

a = 22 inches

Hence the length is 22 inches.

The volume of the frustum of a regular square pyramid with slant height 6 and square bases of edges 5 and 9 is approximately 284.99 cm³, and the surface area is 274 cm².

To calculate the volume and the surface area (SA) of the frustum of a regular square pyramid with a slant height of 6 and bases with edges of length 5 and 9, we use the following formulas:

First, we need to find the perpendicular height (h) using Pythagorean theorem as the slant height is given.

For base edges of 5 (small square base) and 9 (large square base), the areas are:

The perimeters are:

The lateral surface area (LSA) = (P1 + P2) * 6 / 2 = (20 + 36) * 6 / 2 = 168 cm².

Assuming that the slant height is consistent across the frustum, we find 'h' using the Pythagorean theorem:

Let's denote the difference in the side lengths of the squares as 'd'. Therefore, d = (9 - 5) / 2 = 2.

h² + d² = slant height², so h² = 6² - 2² = 36 - 4 = 32 and h = √32.

Now, we use the volume formula:

V = (√32 / 3) * (25 + 81 + √(25 * 81)) = (5.657 / 3) * (106 + 45) = 5.657 * 50.333 = 284.99 cm³, approximately.

For the surface area:

SA = A1 + A2 + LSA = 25 + 81 + 168 = 274 cm².

Step-by-step explanation:

The student needs to use the average rate of change formula correctly. For the function f(x) = 0.5x^2 and the interval [-4, -2], the correct average rate of change is -3.

The student is looking to find the average rate of change of the function f(x) = 0.5x^2 over the interval [-4,-2]. The average rate of change of a function over the interval [a, b] is calculated by the formula: (f(b) - f(a)) / (b - a).

For our function and interval this calculates to (f(-2) - f(-4)) / (-2 -(-4)). f(-2) is 0.5(-2)^2 = 2, and f(-4) is 0.5(-4)^2 = 8. Substituting into the formula gives (2 - 8) / (-2 -(-4)) = -6 / 2 = -3. So the correct average rate of change for f(x) = 0.5x^2 over the interval [-4,-2] is -3.

The condo will be worth approximately $104,786 in 5 years.

To calculate the future value of the condo, we can use the formula: Future Value = Present Value * (1 + Interest Rate)^Number of Years. Given that the condo was bought for $83,000 and will appreciate at a rate of 6% per year, we can substitute these values into the formula to find the future value.

Future Value = $83,000 * (1 + 0.06)^5 = $104,785.81.

Therefore, the condo will be worth approximately $104,786 in 5 years.

The value of the condo will be approximately $111,073 in 5 years.

To find out how much your condo will be worth in 5 years if it appreciates at 6% per year, you can use the compound interest formula:

Future Value (FV) = Present Value (PV) * (1 + Rate)ᵗᶦᵐ

Here:

Plug the values into the formula:

FV = 83,000 * (1 + 0.06)⁵

First, calculate the growth factor:

(1 + 0.06) = 1.06

Next, raise the growth factor to the power of 5:

1.06⁵ = 1.3382

Finally, multiply this result by the present value:

83,000 * 1.3382 = $111,073.

c) 20,000

Step-by-step explanation:

Number of digits = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 = 10,

Number of vowel letters = a, e, i, o, u = 5

Repetition of digits is permitted but repetition of vowel letters is not permitted

Let the password be presented in dash form as shown below:

____ ____ ____ ____ ____ =

  D       D       D       V       V

where:

D = possible number of digits to fill the spot

V = possible number of vowels to fill the spot

Since repetition of digits is permitted, each spot marked as D can be filled with any one of 10 digits from 0 - 9

The first spot marked V has 5 possible options (a, e, i, o, u) & the second spot marked V only has 4 possible options (since repetition of vowels is not permitted).

We then place the number of possibilities in each spot and multiply them to determine the number of passwords possible

10  *  10  *  10  *  5  *  4 = 20,000

Therefore, the number of possible passwords is 20,000

Answer:

-21.

Step-by-step explanation:

x^2 + 4x - 21 = 0

To factor this we need 2 numbers whose sum id + 4 and whose produce is -21.

These are  - 3 and + 7 , so the factors are:

(x - 3)(x + & = 0

x = 3, -7.

Final answer:

The product of the solutions for the quadratic equation x² + 4x - 21 = 0 is -21, as per Vieta's formulas, which states that the product is c/a.

Explanation:

The question is asking for the product of the solutions of a quadratic equation, specifically x² + 4x - 21 = 0. In the context of the quadratic formula, a = 1, b = 4, and c = -21. The quadratic formula is given by x = [-b ± √(b² - 4ac)] / (2a). However, to find the product of the roots, we can apply Vieta's formulas, which states that the product of the roots of a quadratic ax² + bx + c = 0 is c/a.

For the equation in question, the product of the roots would be c/a = (-21)/1 = -21. This is a straightforward application of a standard property of quadratic equations. Therefore, we don't need to find the individual roots to answer the question about their product, saving time and effort.
