Answer: 34,623.23

Since we are rounding to the nearest hundredth we are going to look at the number 2 in the hundreth place. 34,623.226

As you can see the bold 2 is in the hundreth place. We underline it and put an arrow pointing at 6.

Any number that are 5 and up you add 1. Also known as round up.

Any number that are 4 and below you add 0. Also known as round down.

Let's take a look at the 6. We can tell that 6 is greater than 5.

6 > 5

Since 6 is greater than 5 we add 1 to the hundreth place. 2 becomes a 3. Any numbers behind 3 is 0 so you'll get 34,623.23 0. Since the 0 is last in the thousandth place we just remove it. So your answer will be 34,623.23.

Answer:

First, we can find the height of the original cone using the Pythagorean theorem:

height = sqrt(slant height^2 - radius^2) = sqrt(12^2 - 2^2) = sqrt(142) inches

The surface area of the original cone is:

SA = πr(r + √(r^2 + h^2)) = π(2)(2 + √(2^2 + (sqrt(142))^2)) ≈ 46.63 in²

The ratio of the radii of the two cones is 6/2 = 3, so the ratio of their surface areas is 3^2 = 9.

Therefore, the surface area of the similar cone is:

SA = 9 × 46.63 = 419.67 in² (rounded to two decimal places)

So the exact surface area of the similar cone with a radius of 6 inches is 419.67 in².

The cost of students ticket is $37.5and the cost of general admission is $187.5.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, also known as a system of equations or an equation system.

Assume s be the students tickets cost and g be the general admission cost.

From the given information,

⇒  s + g = 225             ..(1)

 5s + 7g = 1500         ..(2)

From equation (1),

s = 225 - g

Plug the value of s in equation (2)

5(225 - g) + 7g = 1500

1125 - 5g + 7g = 1500

                  2g = 1500 - 1125

                  2g = 375

                    g = 187.5

Plug g = 125 in equation (1),

s + 187.5= 225

        s = 225 - 187.5

        s = 37.5

Let the cost of the meal be x.

Adding a tip of 19%:

Answer:

Wyatt should multiply with 1.19.

Step-by-step explanation:

Forming the expression,

→ 1 + (19% of 1)

Now the required number is,

→ 1 + (19% of 1)

→ 1 + ((19/100) × 1)

→ 1 + (19/100)

→ 1 + 0.19 = 1.19

Hence, required number is 1.19.

Answer:letra    b

Step-by-step explanation:

A function assigns the values. The decrease in selling price from 700 units sold to 900 units sold is 10. Thus, the correct option is B.

A function assigns the value of each element of one set to the other specific element of another set.

Price of the unit when 900 units were sold,

P=1200-20s

900 = 1200 - 20s

s = 15

Price of the unit when 700 units were sold,

P=1200-20s

700 = 1200 - 20s

s = 25

Now, the difference in the selling price of the units is,

Difference = 25 - 15 = 10

Hence, the decrease in selling price from 700 units sold to 900 units sold is 10. Thus, the correct option is B.

Answer:

180

Step-by-step explanation:

Divide 540 by 3 to get 180 which is your answer!

Have a good day!

Please mark brainliest!

Solution:

Note that:

Simplify the equation to know how much beats in 1 minute.

The beats per minute in this song is 180 beats per minute.

It can be seen that x = (3 ± √(9 + 32√3)) / 8, which can be expressed in surd form as (3 + √(9 + 32√3)) / 8 or (3 - √(9 + 32√3)) / 8.

To find x using the sine rule, we need to solve the equation:

sine(45) / x = sine(30) / (2x + 2√3)

Simplifying this equation, we have:

(2x - 1) / x = 1 / (2x + 2√3)

Cross-multiplying and simplifying further, we get:

(2x - 1)(2x + 2√3) = x

Expanding the brackets, we have:

\(4x^2 + 4\sqrt3x - 2x - 2\sqrt3 = x\)

Rearranging the terms and simplifying, we get:

\(4x^2 - 3x - 2\sqrt3 = 0\)

Using the quadratic formula, we can solve for x:

x = (-(-3) ± √((-3)^2 - 4(4)(-2√3))) / (2(4))

x = (3 ± √(9 + 32√3)) / 8

Therefore, x = (3 ± √(9 + 32√3)) / 8, which can be expressed in surd form as (3 + √(9 + 32√3)) / 8 or (3 - √(9 + 32√3)) / 8.

Answer:

18.28% probability that at most 210 of those purchases are paid with a credit or debit card.

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

\(E(X) = np\)

The standard deviation of the binomial distribution is:

\(\sqrt{V(X)} = \sqrt{np(1-p)}\)

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

When we are approximating a binomial distribution to a normal one, we have that \(\mu = E(X)\), \(\sigma = \sqrt{V(X)}\).

In this problem, we have that:

\(n = 300, p = 0.725\)

So

\(\mu = E(X) = np = 300*0.725 = 217.5\)

\(\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{300*0.725*0.275} = 7.7339\)

Find the probability that at most 210 of those purchases are paid with a credit or debit card.

Using continuity correction, this is \(P(X \leq 210 + 0.5) = P(X \leq 210.5)\), which is 1 subtracted by the pvalue of Z when X = 210.5. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{210.5 - 217.5}{7.7339}\)

\(Z = -0.905\)

\(Z = -0.905\) has a pvalue of 0.1828

18.28% probability that at most 210 of those purchases are paid with a credit or debit card.

The total cost to run Val’s AC costs for a summer month of 30 days will be $67.5.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Quantity of electricity used in kilowatts is;

1000 watts = 1 kilowatts

2,500 watts = 2.5 kilowatts

Given that Number of hours Val runs AC per day = 5 hours

Number of days = 30 days

Cost of electricity = $0.18 kilowatts per hour

The Cost of Val’s AC to run for a summer month of 30 days can be calculated as;

= Quantity of electricity used × Number of hours Val runs AC per day × Number of days × Cost of electricity

= 2.5 × 5 × 30 × 0.18

= $67.5

The answer to this question: B

The based on this example, we can see that the converse of the Pythagorean theorem does not hold for this particular triangle.

To prove the converse of the Pythagorean theorem, we need to show that if the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.

In the given triangle AABC, with vertices at A(1,6), B(1,1), and C(5,1), we can calculate the lengths of the sides using the distance formula or Pythagorean theorem.

AB = sqrt((1-1)^2 + (6-1)^2) = sqrt(25) = 5

BC = sqrt((5-1)^2 + (1-1)^2) = sqrt(16) = 4

AC = sqrt((5-1)^2 + (6-1)^2) = sqrt(40) = 2sqrt(10)

Now, let's check if AB^2 + BC^2 = AC^2:

AB^2 + BC^2 = 5^2 + 4^2 = 25 + 16 = 41

AC^2 = (2sqrt(10))^2 = 4(10) = 40

Since AB^2 + BC^2 is not equal to AC^2, the given triangle AABC does not satisfy the condition for the converse of the Pythagorean theorem.
