Answer:3 ⋅ ( 4 ⋅ 5 ) = 23 a ⋅ b = a ( b a ) + b = a = 2

Step-by-step explanation:

The common fraction for the given expression is 60/47.

A fraction represents part of a whole. When something is broken up into a number of parts, the fraction shows how many of those parts you have.

Given that an expression, 3*(4*5) such that, a*b= ab/a+b

Solving the expression as per the given formula,

4*5 = 4×5/(4+5) = 20/9

Now,

3*(4*5) can be written as, 3*20/9

Therefore,

3*20/9 = 3×20/9/(3+20/9)

= 20/3×9/47

= 60/47

Hence, the common fraction for the given expression is 60/47.

Answer:

3/4

Step-by-step explanation:

From the above question, total number of cats in the litter = 7

We are told in the question that 4/7 of the kittens are white

This means

The number of kittens that are not white = 7 - 4/7 = 3/7

The number of kittens that are female and white = 3/7

This question is a conditional probability question

The probability that your cousin will choose a female kitten given that it is white is calculated as:

Probability that the kittens are female and white ÷ Probability that the kittens are white

= 3/7 ÷ 4/7

= 3/7 × 7/4

= 3/4

Therefore, probability that your cousin will choose a female kitten given that it is a white is 3/4

Answer:

Answer:

b.

[tex] {4}^{8} [/tex]

Step-by-step explanation:

With the same base you just add the exponents.

Answer:

1.) Newton 3rd law

2.) Newton 1st law

3.) Newton 2nd law.

Step-by-step explanation:

1.)  I pull on the Earth because Earth pulls on me. This can be identified as Newton 3rd law of motion. The law state that, in every action, there must be equal and opposite reaction.

As the earth pulls on you, the reaction to that action which is equal and opposite is you pulling back on earth.

2.) The velocity of a falling object isn’t constant because Earth’s gravity exerts a force on it. This can be identified by Newton 1st law of motion which state that: an object will continue to be at rest or in a linear motion except an external force act on it.

The velocity of a falling object suppose to be constant if there is no external force. But it isn’t constant because Earth’s gravity exerts a force on it.

3.) If air resistance is ignored, the acceleration of a falling object is equal to the ratio of the force of gravity to mass. This can be identified by Newton 2nd law of motion which state that: The rate of change in momentum is proportional to the applied force. Or

F = ma

Where F = applied force

M = mass of the object

a = acceleration

If air resistance is ignored,

F = mg

where g = acceleration due to gravity.

1. Newton 3rd law

Where A = the total

P is equal to the starting amount

A = $40,000

r = 0.08 (8%)

t = 15

[tex]40,000 = P(1 +(0.08* 15))\\40,000 = P(1+1.2)\\40,000 = P(2.2)\\\frac{40,000}{2.2} = P\\ \frac{200,000}{11} = P\\P = $18181.8181818181...[/tex]

[tex]Point\ C = (2,-1)[/tex]

Step-by-step explanation:

Given

[tex]A = (2,-6)[/tex]

[tex]B = (10,2)[/tex]

[tex]m:n = 5:3[/tex]

Required

Determine the coordinates of C

Since, point D divides line AB in ratio, 5 : 3;

We start by calculating the coordinates of D;

This is done as follows;

[tex]D(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]

Where

[tex](x_1,y_1) = (2,6)[/tex]

[tex](x_2,y_2) = (10,2)[/tex]

[tex]m:n = 5:3[/tex]

[tex]D(x,y) = (\frac{5 * 10 + 3 * 2}{5+3},\frac{5 * 2 + 3 * -6}{5+3})[/tex]

[tex]D(x,y) = (\frac{50 + 6}{8},\frac{10 - 18}{8})[/tex]

[tex]D(x,y) = (\frac{56}{8},\frac{-8}{8})[/tex]

[tex]D(x,y) = (7},-1)[/tex]

Since AC is vertical

Then, Point C has the same x coordinate as A

[tex]x-coordinate = 2[/tex]

Similarly;

Since CD is horizontal

Then, Point C has the same y coordinate as D

[tex]y-coordinate = -1[/tex]

Hence,

[tex]Point\ C = (2,-1)[/tex]

Now we can use ratios to solve

8 cookies          x cookies

-------------   = -----------------

90 seconds         225 seconds

Answer:

Step-by-step explanation:

Since opposite angles in a parallelogram are congruent, ∠B = ∠D which means:

5y + 31 = 96

5y = 65

y = 13°

Additionally, opposite sides of a parallelogram are congruent, therefore AB = CD which means:

x² - 18 = 7x

x² - 7x - 18 = 0

(x - 9)(x + 2) = 0

x = 9° or -2°

Answer:

SINCE IT IS A PARALLELOGRAM,

AB=CD

Answer:

$3,033.56

Step-by-step explanation:

(see attached for reference)

The formula for compound interest is given by

A = P [ 1 + (r/n) ]^(nt)

Where,

A = final amount (we are asked to find this)

P = principal = given as $1500

r = annual interest rate = 9% = 0.09

n = 2 (for compounding semi-annually)

t = time, given as 8 years

Substituting the above into the equation:

A = P [ 1 + (r/n) ]^(nt)

A = 1500 [ 1 + (0.09/2) ]^[(2)(8)]

A = 1500 [ 1.045) ]^[16]

A = $3,033.56

Answer:

1.02 cm²

Step-by-step explanation:

An equilateral triangle is a triangle with all three sides of equal length.

The perimeter of the triangle made by Lawrence is 18 cm. Which is calculated as follows:

perimeter of equilateral triangle = 3*side

Therefore, each side is 18/3 = 6 cm long

Area of equilateral triangle =  √3/4*side²

Area obtained by Lawrence = √3/4*5.8² = 14.57 cm²

Actual area of the triangle = √3/4*6² = 15.59 cm²

Absolute Error = | Measured Value - Actual Value |

Absolute Error = |14.57 - 15.59| = 1.02 cm²
