Answers

Answer:

1a)81 b)54 c)27 d)0

Step-by-step explanation:

for number one the answer is 27 x what is given

Answer:

a) 8; b) 12; c) 6; d) 130.3 cm

Step-by-step explanation:

You want the number of small cubes painted on 3, 2, 1, and 0 faces if the outside surface of a cube comprised of 27 small cubes is painted. You also want the height of 200 L of water in a tank of 50 cm radius with a 20 cm radius hole in the middle.

1. Cubes

The number of cubes painted on 3 faces is the number of corner cubes: 8.

The number of cubes painted on 2 faces is the number of center-edge cubes, 12.

The number of cubes painted on one face is the number of center-face cubes, 6.

The number of cubes with no painted faces is the number of cubes buried inside, 1.

The painting is ...

3 faces: 82 faces: 121 face: 60 faces: 1

The total is 27, as it should be.

2. Height

The area of the base of the part holding water is ...

  π(50² -20²) = π(2500 -400) = 2100π cm²

The height of 200 L of water will be h, where the volume of the figure is ...

  V = Bh

  V = (2100π cm²)h = 200·1000 cm³

  h = 200/(2.1π) cm ≈ 30.3 cm

The height of the water in the tank will be about 30.3 cm.

__

Additional comment

When working with volumes in liters, it is often convenient to work with dimensions in decimeters (dm), where 1 dm = 10 cm. This is because 1 dm³ = 1 L.

Here, the area is π(5² -2²) = 21π dm², so the height is (200 dm³)/(21π dm²) ≈ 3.03 dm = 30.3 cm.

The average surface temperature of a red giant star is much cooler than that of a white dwarf star. Suppose a white dwarf has a surface temperature of 1.2 x 10*4 Kelvin (abbreviated K), which is 4 times the temperature of a red giant star. WHat is the surface temperature of the red giant star?

Answers

Answer: 3000 Kelvin

Step-by-step explanation

Let the surface temperature of the red giant star = x

Surface temperature of a white dwarf star = 4x

4x = 1.2 × 10^4 K

    = 1.2 × 10,000 K

    = 12,000 K

4x = 12,000 K

x = 12000 ÷ 4

  = 3,000 K

Maxwell invested a total of $100,000. He invested his money in three different accounts. He invested $35,000 at 10% annual interest rate, $42,000 at 8% annual rate, and the remainder at 14% interest rate. How much interest did Maxwell receive in one year?

Answers

Step-by-step explanation:

Sure! Here's the step-by-step calculation:

1. Calculate the interest earned on the first investment:

$35,000 * 10% = $3,500

2. Calculate the interest earned on the second investment:

$42,000 * 8% = $3,360

3. Calculate the amount invested in the third account:

Total investment - (First investment + Second investment)

$100,000 - ($35,000 + $42,000) = $23,000

4. Calculate the interest earned on the third investment:

$23,000 * 14% = $3,220

5. Add up the interest earned from all three investments:

$3,500 + $3,360 + $3,220 = $10,080

Therefore, Maxwell received $10,080 in interest in one year.

The answer is 10,080.

PLEASE PLEASE HELP (DUE ASAP)! I was struggling a lot with this and I was hoping for an accurate answer! Name the correct angle using the given diagram

Answers

Answer:

Alright Ima jsut say common phrases and do em at the end

Veritcal angles:

Well these angles are equal and always across form each other. Too determine if its a vertical angle, if you see an “x” Like shape, you can draw a maximum of two lines, one horizontal, one vertical. The number those lines tough are vertical the fore the SAME.

Complementary angles:

These are 2 or more angles that add up to 90 degrees. You can have like 20 different angles with different numbers, as long as they add up to 90 degrees. 90 degrees is a right angle so no matter what, it has to equal 90 degrees from all angles.

Supplementary angles:

These are 2 or more angles that add up to 180 degrees or a straight line more common. As long as all the angles add up to 180, its supplementary.

Adjacent angles:

These are angle show lie next to each other. They don’t have anything special, their just next to each other. Ima use an example form the graph. Take for example the angle RNX. XNE is adjacent, its lies right next to it. Another Example could be KND. DNE is adjacent, right next to it.

in his first four years of coaching football, Coach Delgato's team won 5 games the first year, 10 games the second year, 8 games the third year, and 7 games the fourth year. How many games does the team need to win the fifth year to have an average of 8 wins per year?

Answers

he will need to wins 14 games

The team needs to win 10 games in the fifth year to have an average of 8 wins per year over the five-year period.

To find out how many games the team needs to win in the fifth year to have an average of 8 wins per year over the five-year period, we can use the following equation:

(5 + 10 + 8 + 7 + x) / 5 = 8

Here, x represents the number of games the team needs to win in the fifth year.

To solve for x, we can simplify the equation:

(30 + x) / 5 = 8

Now, we can cross-multiply:

30 + x = 40

Subtracting 30 from both sides of the equation, we get:

x = 10

Therefore, the team needs to win 10 games in the fifth year to have an average of 8 wins per year over the five-year period.
