Answer:

20!

Step-by-step explanation:

Answer:

2880 or 20!

Step-by-step explanation:

Whenever you have a number with a (!) after it, it means that the number is in factorial. So if you have a equation like 3!, it would be equal to 3·2·1. So in that case—

5! = 1·2·3·4·5

We can multiply this sequence of numbers simply.

1·2·3·4·5=120

Now, since we have the first factorial, we move on to the second.

4!=1·2·3·4

Again, we can multiply this sequence simply.

1·2·3·4=24

Now we move on to the final step. We have factoriazed the numbers, so we can substitute those in the equation.

120·24

Now we can finally multiply these 2 numbers to get your answer.

120·24=2880

That is the evaluation.

If you want to simplify the expression, multiply the numbers.

4!·5!=20!

Answer: Top row: -8. 2nd row: 1, -9. 3rd row: -5, 6, -15. 4th row: 3,-8, 14, -29.

Step-by-step explanation: Work from the bottom up.

The numbers that add up to -15 (to the left of -29) can be found by subtracting 15 from 29. 29-15=14. -29+14=-15.

The numbers that add up to -5 (to the left of -8) can be found by subtracting 5 from 8. 8-5=3. -8+3=-5.

The numbers that add up to 1 (next to -5) can be found by adding 1 and 5. 1+5=6. -5+6=1.

To find the number next to 1, add -15 and the number we just found between -5 and -15 (6). -15+6=-9.

To find the top number, add -9 and 1. -9+1=-8.

This explanation doesn't make the most sense, but it's how I found them.

Height, 24, 80, and cubic feet

Step-by-step explanation:

I just did this on edge-unity and it gave me that.

Area of the regular hexagon base is 24√3 square feet and the volume of the same is 80√3 cube feet.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given that,

The base of a right pyramid is regular hexagon.

Edge length of regular hexagon = 4 feet

Area of equilateral triangle with sides 4 feet = 4√3 square feet

A regular hexagon can be divided in to 6 equilateral triangles.

Area of the base of the pyramid = 6 × area of an equilateral triangle

                                                     = 6 × 4√3

                                                     = 24√3 square feet

The volume of a hexagonal pyramid = [tex]\frac{\sqrt{3} }{2}[/tex] b² h

where h is the height and b is the edge length of the base.

Height of the pyramid = 10 feet and b = 4 feet

Volume = [tex]\frac{\sqrt{3} }{2}[/tex] 4² × 10 = 80√3 cube feet

Hence the area of the base is 24√3 square feet and volume is 80√3 cube feet.

Step-by-step explanation: Its D.

Circumference equals 2 * pi * radius. Your radius is 37 feet. So 2*2.14*37

and that equals 232.36

Final answer:

The circumference of a circular playground with a radius of 37 feet, using 3.14 for pi, is approximately 232.36 feet. The correct answer is option D.

Explanation:

To calculate the circumference of a circular playground, we can use the formula C = 2πr, where π (pi) is approximately 3.14 and r is the radius of the playground. In this case, the radius is given as 37 feet.

Substituting the values, we get:

C = 2 × 3.14 × 37

C = 2 × 3.14 × 37

C = 6.28 × 37

C ≈ 232.36 feet

Therefore, the approximate circumference of the playground is 232.36 feet.

When you decrease £262 by 39% using the multiplier method, you get £159.82 as the result.

To decrease £262 by 39% using the multiplier method, follow these steps:

Convert the percentage decrease to a decimal:

39% = 0.39

Calculate the multiplier (the factor by which you'll multiply the original amount to decrease it):

Multiplier = 1 - Percentage Decrease (as a decimal)

Multiplier = 1 - 0.39

Multiplier = 0.61

Multiply the original amount by the multiplier to find the decreased amount:

Decreased Amount = Original Amount × Multiplier

Decreased Amount = £262 × 0.61

Now, calculate the decreased amount:

Decreased Amount = £159.82

Answer:

  A) decreasing. Salt concentration is being reduced.

  B) 5%. The more 5% solution that is added, the closer the mixture becomes to 5%.

Step-by-step explanation:

A) Increasing values of x result in decreasing values of C(x), so the function is decreasing.

This means that when a lower concentration of salt solution is added to one of higher concentration, the result is a decrease in the concentration of salt in the mixture.

__

B) As x gets very large, C(x) approaches 5. The horizontal asymptote is C=5.

In the context of the problem, it means that as the solution contains more and more 5% brine, the concentration of salt in the mix approaches 5%.

Answer:

-22

Step-by-step explanation:

f(x) = -x2 + 4x - 9

g(x) = x - 8,

g(f(-1))

First find f(-1)

f(-1) = - (-1)^2 + 4(-1) - 9 = -1 -4-9 = -14

The find g(-14)

g(-14) = -14-8 = -22

Both types of quadrilaterals do exist, so neither of them is correct.

Well, actually neither of the two kids is correct.

There are quadrilaterals that have internal right angles, such as the square or the rectangle, but there are also quadrilaterals whose internal angles do not measure 90°, like the case of the rhombus.

Then there are quadrilaterals with right angles and quadrilaterals without right angles, then neither Kathleen nor Gray are correct, because both types of quadrilaterals do exist.

Answer:

No

Step-by-step explanation:

The rate per second for copies will be as follows

First machine

Since it takes 8 seconds to make 5 copies hence rate per second is equivalent to 5/8 copies per second

Second machine

First, convert its time into seconds. Given that 1 min has 60 seconds then 24 mins will have 24*60=1440 seconds

During this time, the machine makes 16 copies. Therefore, the rate per second is 16/1440 which when simplified is 1/90 copies per second.

Clearly, these two rates are different.

Answer:

Let g = length of green ribbon.

So 1.5g + 6.5 = length of blue ribbon.

g + 1.5g + 6.5 = 50.25

g = 17.5 meters of green ribbon

1.5(17.5) + 6.5 = 32.25 meters of blue ribbon

Step-by-step explanation:

The wind speed can be found using the Law of Cosines. It will be the unknown side of a triangle with sides 6 and 5 and included angle 30°.

  s^2 = 6^2 +5^2 -2·6·5·cos(30°) ≈ 9.038476

  s ≈ √9.038476 ≈ 3.0064 . . . . m/s

The direction of the wind can be found from the Law of Sines, which tells us the relationship of the internal angle A to velocity vector a is ...

  sin(A)/a = sin(30°)/3.0064

  A = arcsin(5/3.0064·sin(30°) ≈ 56.26°

To find the desired angle, we must add 180° to this value.

The wind is blowing 3.0 m/s in direction 236.3°.
