Answer:

Which algebraic expression shows the average melting points of helium, hydrogen, and neon if h represents the melting point of helium, j represents the melting point of hydrogen, and k represents the melting point of neon?

Step-by-step explanation:

The present value of an ordinary annuity of $350 each year for five years with a 4 percent opportunity cost is $1,551.88, calculated using the present value formula for annuities.

To find the present value of an ordinary annuity, you can use the formula for the present value of an annuity:

[tex]\[ PV = Pmt \times \frac{{1 - (1 + r)^{-n}}}{{r}} \][/tex]

Where:

- PV is the present value of the annuity,

- Pmt is the annual payment (in this case, $350),

- r is the interest rate per period (in decimal form),

- n is the number of periods (in this case, 5 years).

Given that the opportunity cost (interest rate) is 4%, or 0.04 in decimal form, and there are 5 years of payments, we can plug these values into the formula:

[tex]\[ PV = 350 \times \frac{{1 - (1 + 0.04)^{-5}}}{{0.04}} \][/tex]

Let's calculate:

[tex]\[ PV = 350 \times \frac{{1 - (1.04)^{-5}}}{{0.04}} \][/tex]

[tex]\[ PV = 350 \times \frac{{1 - (0.8227)}}{{0.04}} \][/tex]

[tex]\[ PV = 350 \times \frac{{0.1773}}{{0.04}} \][/tex]

[tex]\[ PV \approx 350 \times 4.4325 \][/tex]

PV = $1551.88 (Approximately)

So, the present value of the annuity, assuming an opportunity cost of 4%, is approximately $1551.88.

Answer:

Step-by-step explanation:

cube root of 3375 =m

We need to solve the equation for m

[tex]\sqrt[3]{3375} = m[/tex]

In order to solve for m we need to find the cube root of 3375

3375 can be written as 3 times 3 times 3 times 5 times 5 times 5

[tex]\sqrt[3]{3375} = m[/tex]

[tex]\sqrt[3]{3 \cdot 3 \cdot 3 \cdot 5 \cdot 5 \cdot 5} = m[/tex]

For same three factors inside the cube root we pull out one factor outside the cube root

[tex]\sqrt[3]{3 \cdot 3 \cdot 3} = 3[/tex]

[tex]\sqrt[3]{3 \cdot 3 \cdot 3 \cdot 5 \cdot 5 \cdot 5} = m[/tex]

[tex]3 \cdot 5 = m[/tex]

m= 15

The value of the variable that makes the statement true is

m = 15

The given equation is:

[tex]\sqrt[3]{3375} = m[/tex]

We are looking for a number that we can multiply by itself 3 times to get 3375

Note that the given equation can be re-written as:

[tex]m =3375^{\frac{1}{3}[/tex]

This can be further simplified as:

[tex]m=15^{3(\frac{1}{3} )}\\\\m=15[/tex]

Therefore, the value of the variable that makes the statement true is m = 15

By dividing Tanya's swimming goal of 30 miles by her daily swimming rate of 3/4 mile, we find that it will take her 40 days to reach her goal.

To calculate how many days it will take Tanya to reach her goal of swimming 30 miles by swimming 3/4 mile per day, we need to divide the total goal distance by the daily swimming distance. Therefore, the calculation is as follows:

Divide 30 miles by 3/4 mile.

Since dividing by a fraction is equivalent to multiplying by its reciprocal, we multiply 30 miles by 4/3.

30 miles  * 4/3 = 120/3 = 40 days.

Hence, it will take Tanya 40 days to reach her goal of swimming 30 miles if she swims 3/4 mile each day

The volume of a pyramid with a base area of 10 square inches and a height of 9 inches will be 30 cubic inches.

Suppose the base of the pyramid has length = L units and width = W units, slant height = K units, and the height of the pyramid is of H units.

Then the volume of the pyramid will be

V = (L × B × H) / 3

V = (Base area x H) / 3

The volume of a pyramid varies jointly with the base area of the pyramid and its height.

The volume of one pyramid is 24 cubic inches when its base area is 24 square inches and its height is 3 inches.

Then the volume of a pyramid with a base area of 10 square inches and a height of 9 inches will be

V = (10 x 9) / 3

V = 30 cubic inches

The volume of a pyramid is obtained from the joint variation relationship with its base area and height. Given a certain pyramid's dimensions, we can determine the volume of another pyramid if we know its base area and height. The volume of the second pyramid is 30 cubic inches.

The student's question pertains to joint variation, a concept in mathematics, specifically applied here to understand how the volume of a pyramid relates to its base area and height. For a pyramid, this relationship can be expressed as V = k * A * H, where V is volume, A is base area, H is height, and k is the constant of variation.

First, we find the value of 'k' using the given pyramid's measurements; so 24 = k * 24 * 3 gives us k = 1/3.

Then, we use this constant to find the volume of the other pyramid whose base area is 10 square inches and height is 9 inches. Therefore, V = 1/3 * 10 * 9, which simplifies to V = 30 cubic inches.

Subtraction of  8-4 1/2 is 3 1/2.

The correct option is D.

To subtract 8 - 4 1/2, we need to convert the mixed number 4 1/2 into an improper fraction.

To do this, we multiply the whole number (4) by the denominator (2), which gives us 8. Then we add the numerator (1) to get 9. So, 4 1/2 is equivalent to the improper fraction 9/2.

Now, we can subtract 8 from 9/2. To subtract fractions, the denominators must be the same. We can rewrite 8 as 8/1 to have a common denominator with 9/2.

Subtracting 8/1 from 9/2 gives us (8 - 9/2).

To subtract fractions, we need a common denominator, which is 2 in this case.

Converting 8/1 to have a denominator of 2, we get 16/2.

Now we can subtract the fractions: (16- 9)/2 = 7/2.

Therefore, the answer is 7/2, which can also be expressed as 3 1/2.

So the correct answer is D. 3 1/2.

By defining the shorter leg of the triangle as 'x' and applying the Pythagorean Theorem to solve the given equations, we find that the shorter leg is 3cm, the longer leg is 12cm, and the hypotenuse is 15cm.

Let's define the shorter leg of the triangle as 'x'. As given, the longer leg would be '2x + 6' and the hypotenuse would be '2x + 9'.

To solve for the lengths of the sides, let's use the Pythagorean Theorem, which says that the square of the hypotenuse is equal to the sum of the squares of the other two sides. So, the equation would be (2x + 6)^2 + x^2 = (2x + 9)^2.

Solve this equation by expanding, collecting similar terms, and factoring. You'll end up with x = 3. Therefore, the shorter leg of the triangle is 3cm, the longer leg is 2x + 6 = 2*3 + 6 = 12cm, and the hypotenuse is 2x + 9 = 2*3 + 9 = 15cm.
