A gold mine has two​ elevators, one for equipment and another for the miners. The equipment elevator descends 66 feet per second. The elevator for the miners descends 1616 feet per second. One​ day, the equipment elevator begins to descend. After 2323 ​seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 1616 ​seconds? At that​ time, which elevator is​ deeper? The position of the equipment elevator relative to the surface is negative 234−234 feet. The position of the elevator for the miners relative to the surface is nothing feet.

Answers

Given that the equipment elevator descends at 6 feet per second.

The total number of seconds travelled by the equipment elevator is 23 + 16 = 39 seconds.

Thus the position of the equipment elevator relative to the surface is given by -(6 x 39) = -234 feet.

Given that the miners elevator descends at 16 feet per second.

The total number of seconds travelled by the miners elevator is 16 seconds.

Thus, the position of the miners elevator relative to the surface is given by -(16 x 16) = -256 feet.

At that time the miners' elevator is deeper.

474: the 4 in the ones place is _____ the value of the 4 in the hundreds place.

Answers

Final answer:

In the number 474, the 4 in the ones place is less than the value of the 4 in the hundreds place by a factor of 100 because each position to the left in the place value system is worth ten times more than the one to its right.

Explanation:

The question deals with the concept of place value in mathematics. Specifically, it requires understanding how the value of a digit changes based on its position within a number. In the number 474, the 4 in the ones place has a value of 4, whereas the 4 in the hundreds place has a value that is 100 times greater, since each move to the left in place value represents a multiplication by 10. Therefore, the 4 in the ones place is less than the value of the 4 in the hundreds place. Here's a simple breakdown of the place values in the given number 474:

The first 4 (from left to right) is in the hundreds place, so its value is 4 x 100 = 400.The second 4 is in the ones place, so its value is 4 x 1 = 4.

Since 1 is less than 100, the 4 in the ones place is worth less than the 4 in the hundreds place by a factor of 100.

Final answer:

The value of the 4 in the ones place is 10 times the value of the 4 in the hundreds place.

Explanation:

The 4 in the ones place is 10 times the value of the 4 in the hundreds place.

The running aces card team won $548 playing in poker tournaments last year. the winnings were split evenly among the p players. how much of money did each player receive?

Answers

Each player received 548/p dollars. To find this, simply consider the total amount of money the card team won, which is given as $548. Then consider that that the winnings are being distributed evenly, so each person gets an equal share. Since we are told that there are p players on the team, but not given a specific value for p, all we can do is give the general form of the expression for dividing $548 dollars among p players.

Answer:

Each player received 548/p dollars.

Prove that the cube root of 2 is irrational.

Answers

The cube root of 2 is irrational. The proof that the square root of 2 is irrational may be used, with only slight modification. Assume the cube root of 2 is rational. Then, it may be written as a/b, where a and b are integers with no common factors. (This is possible for all nonzero rational numbers). Since a/b is the cube root of 2, its cube must equal 2. That is, (a/b)3 = 2 a3/b3 = 2 a3 = 2b3. The right side is even, so the left side must be even also, thatis, a3 is even. Since a3 is even, a is also even (because the cube of an odd number is always odd). Since a is even, there exists an integer c such that a = 2c. Now, (2c)3 = 2b3 8c3 = 2b3 4c3 = b3. The left side is now even, so the right side must be even too. The product of two odd numbers is always odd, so b3 cannot be odd; it must be even. Therefore b is even as well. Since a and b are both even, the fraction a/b is not in lowest terms, thus contradicting our initial assumption. Since the initial assumption cannot have been true, it must be false, and the cube root of 2 is irrational.

Mark has a container in the shape of a cube. He uses 64 cubes with side lengths of 1 inch to completely fill the container. What is the edge length of the container?

Answers

This means the area is 64 inches^2:

x * x = 64
x = 8

Hope this helps!

Answer:

4 inches is the edge length of the container.

Step-by-step explanation:

Length of the small cubes = a = 1 inch

Volume occupied each small cube = v = [tex]a^3=(1 inch )^3= 1 inches^3[/tex]

Length of the big cube = A

Volume of the big cube = V

[tex]V=A^3[/tex]

He uses 64 cubes with side lengths of 1 inch to completely fill the container.

[tex]V=64\times v=64\times 1 inches^3[/tex]

[tex]A^3=64\times 1 inch^3[/tex]

A = 4 inch

4 inches is the edge length of the container.

Solve the proportion. 2/8 = -30/x

Answers

To solve a proportion set it up like
[tex]\frac{2}{8} = -\frac{30}{x} [/tex]

Now cross multiply the -30 and the 8 so -30 x 8 = -240
Now take the -240 and divide it by 2
[tex] \frac{-240}{2} = -120[/tex]
So x = -120 

Answer = 120

The solution to the proportion 2/8 = -30/x is x = -120, found by cross multiplying and simplifying the resulting equation.

To solve the proportion 2/8 = -30/x, we will cross multiply to find the value of x. After cross multiplying, we obtain 2x = -30  imes 8. Simplifying this gives us 2x = -240, and dividing both sides by 2 yields x = -120. So the solution to the proportion is x = -120.

Scott and Teri read mystery novels. Teri has read 3 less than 5 times as many as Scott. She has read 17. How many has Scott read?

Answers

Scott read 4. Put it this way: x=4. If = 4, then put it into an equation. 5x-3= 17. So, you add three to both sides, then it comes out as this: 5x= 20. Divide by five, and you get x= 4.
Setup an equations:
S = # Scott has read
T = # Teri has read

T = 5S - 3   (3 less than means subtraction but switch term order)
17 = 5S - 3 ( substitute 17 for T because Teri read 17)
4 = S (when you solve the equation)
Therefore, Scott read 4 books.

In the diagram, AB = 10 and AC = 2√10. What is the perimeter of △ABC?

A. 10 units
B. 10 + 2√10 units
C. 20 units
D. 20 + 2√10 units

Answers

Answer:

D. 20 + 2√10 units

Step-by-step explanation:

Perimeter is the distance all round a figure.


AB = 10. This is given in the question


AC = √((3-5)²+(4--2)²


= √(4+36)


=√40 = 6.32 units


BC = 5 - -5 = 10 units



Perimeter = AB+AC+BC


= 10+6.32+10


= 26.32 units

25

65

Answers

tan A = 2.1445
A = tan^(-1) 2.1445 = 64.999 ≈ 65°
In a right triangle:
A + B = 90°
65° + B = 90°
B = 90° - 65° = 25°
Answer:
A ) 25° (or your first option)

The requried measure of angle B is 25 degrees. Option A is correct.

What is the triangle?

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

Here,
In a right triangle, the tangent of an acute angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

Let A be one of the acute angles of the right triangle. Then, we have:

tan(A) = opposite/adjacent

Given that the tangent of angle A is 2.1445, we can write:

2.1445 = opposite/adjacent

Since angle B is also an acute angle of the same right triangle, we have:

tan(B) = opposite/adjacent

But since the sum of the angles of any triangle is 180 degrees, and one of the angles in this triangle is a right angle (90 degrees), we have:

A + B + 90 = 180

B = 90 - A

Substituting the expression for B into the equation for the tangent of angle B, we get:

tan(90 - A) = opposite/adjacent

tan(90 - A) = (1/tan(A)) x adjacent/opposite

tan(90 - A) = (1/2.1445) x adjacent/opposite

tan(90 - A) = 0.466

Taking the inverse tangent of both sides, we get:

90 - A = tan⁻¹0.466)

90 - A = 25.38

A = 90 - 25.38

A = 64.62

Therefore, the measure of angle B is,
B = 90 - A
  = 90 - 64.62 = 25.38 degrees

Thus, the requried measure of angle B is 25 degrees.

Find three solutions of the equation (x^2-9)(x^3-8)=0

Answers

(x^2-9)(x^3-8)=0

as you can see that (x^2-9) is in the form of a^2 - b^2 which equals (a+b)(a-b)

x^2 - 9
= (x)^2 -(3)^2
= (x+3)(x-3)


now, the equation becomes
(x+3)(x-3)(x^3-8)=0

(x+3) =0
x = -3


(x-3) = 0
x = 3

x^3 -8 = 0
x^3 = 8
x = cube rt. 8
= 2

so, the three solutions are -3, 3 and 2.
