The pool is 1 meter deep.
The pool is 2 meters deep.
The toy falls at a rate of at least a Negative one-half meter per second.

Answer:

112.5

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

In this problem, we are asked to determine the degree of the given expression 12X4 - 8X + 4X2 -3. To answer this, first, we need to arrange the mathematical expression in descending order with respect to its power such as the new arrangement will become 12x4 + 4x2 -8x -3. The degree is clearly visible and it is 4. Therefore, the answer to this problem is is 4.

Step-by-step explanation:

area = ( base 1 + base 2 ) ÷ 2 x height

50 = ( 10 + 15) ÷2 x height

50 ÷ 12.5 = height

height = 4

Answer:

5

Step-by-step explanation:

We are given the expression 1/2x + 2 and are asked to find the value when x = 6.

To solve, all we need to do is to substitute x with 6 :

1/2(6) + 2

Multiply 6 by the 1 in the fraction :

6/2 + 2

Divide 6 by 2 :

3 + 2

Add :

Answer:

The ladder will reach a height of 9.8 foot

Step-by-step explanation:

Given

Initial Position

[tex]L = 25ft[/tex] --- Length of the ladder

[tex]h = 15ft[/tex] --- height against the wall

New position

[tex]L = 25ft[/tex] --- Length of the ladder

[tex]B = 3ft[/tex] --- 3 feet farther from the wall

Required

Determine the new height the ladder will reach

The question is illustrated using the attached image.

Where

[tex]\triangle ABC[/tex] represents the initial position of the ladder

[tex]\triangle DBE[/tex] represents the new position of the ladder

The new height is represented with BD

Using Pythagoras theorem on [tex]\triangle DBE[/tex]

[tex]DE^2 = BE^2 + BD^2[/tex]

[tex]BE = BC + CE = 20 + 3 = 23[/tex]

[tex]BD = x[/tex]

[tex]DE =25[/tex] --- length of the ladder

So, the expression becomes

[tex]25^2 = 23^2 + x^2[/tex]

[tex]625 = 529 + x^2[/tex]

Collect like terms

[tex]x^2 = -529 + 625[/tex]

[tex]x^2 = 96[/tex]

Take positive square roots of both sides

[tex]x = \sqrt{96[/tex]

[tex]x = 9.8ft[/tex] --- approximated

Answer:

  14.7

Step-by-step explanation:

The law of sines tells you side lengths are proportional to the sine of the opposite angle.

  x/sin(46°) = 7/sin(20°)

  x = 7(sin(46°)/sin(20°)) ≈ 14.7

The value of x is about 14.7.

The newer machine works at a unit rate of

(5400 cans) / (180 min) = 30 cans/min

while the older machine operates at

(5400 cans) / (217 min) ≈ 24.88 cans/min

So working together, the two machines work at a rate of about 54.88 cans/min. Producing 5400 cans would then take about

(5400 cans) / (54.88 cans/min) ≈ 98.39 min

Answer:

Answer:

option 1

Step-by-step explanation:

Option 1 . the value after 20 years can be determined using this formula

FV = P (1 + r)^n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

5000 x (1.25)^20 = $433,680.87

Option 2 = 5,000 x 20 = $100,0000

Option 1 has a higher value in 20 years

Step-by-step explanation:

Miko's work is not shown in this question. Regardless, her process of using multiplication to check her work is correct. When performing a division problem, you can multiply the quotient by the divisor and the product of this multiplication process should be equal to the dividend of the division problem. For example,

5 / 5.3 = 0.9434

0.9434 * 5.3 = 5

Step-by-step explanation:

When analysing a project, one must try to find out everything that could impart on the success of the project such that any problems can be fixed and any potential problems be made contingencies for.

This is why it is here that you check to see whether and which goals are conflicting so that they can be fixed or aligned to ensure that the project comes out as a success.

Answer:

OK=9.9

Step-by-step explanation:

KJ and LJ both are on the circumference, are secants and coincides at the same outer point so they are equal.

JK=LJ so JK=13.2

Tangents are perpendicular to radius so the triangle in the circle is a right triangle.

Apply pythagorean theorem to find OK

[tex] {x}^{2} + 13.2 {}^{2} = 16.5 {}^{2} [/tex]

[tex]x = 9.9[/tex]

The number of milkshake cups will be 9³/₅.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Robert has two and two-fifths cups of chocolate syrup left in his freezer. He uses one-fourth cup of chocolate syrup when he makes a milkshake.

The number of milkshakes will be calculated as,

Number = 2²/₅ ÷  1 / 4

Number = (12 / 5 ) ÷ ( 1/ 4 )

Number = ( 12 x 4 ) ÷ 5

Number = 48 ÷ 5

Number = 9³/₅
