The time taken by 3 electricians to complete the work is 9 1/3 hours.

When one quantity's value rises relative to another's decrease or vice versa, it is said that the two are inversely proportionate.

It implies that the two quantities exhibit opposing behaviors in nature. For instance, the relationship between time and speed is inverse.

If x and y are inversely proportionate to each other

=> x ∝ 1/y  

=> xy = k    [ where 'k' is proportionality constant ]

Here we have

The time required to complete a job varies inversely to the number of people working. It took 4 hours for 7 electricians to wire a building.

Let x be the time and y be the number of people

Given that the time required to complete a job varies inversely to the number of people working.  

=> xy = k ---- (1)  [ Since they are inversely proportional to each other ]    

Given that it took 4 hours for 7 electricians to wire a building.  

=> 4(7) = k  

=> k = 28

Substitute k = 28 given number of electricians y = 3 in equation (1)

=> x (3) = 28

=> x = 28/3 = 9 1/3hrs

Therefore,

The time taken by 3 electricians to complete the work is 9 1/3 hours.

The percent of the bug eaten each day is 67% and the percent of the bug remaining each day is 33%.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

f(x) = 500 (0.67)ˣ

Part A :

x = 0 ⇒ f(x) = 500 (0.67)⁰ = 500

x = 1 ⇒ f(x) = 500 (0.67)¹ = 335

x = 2 ⇒ f(x) = 500 (0.67)² = 224.45

x = 3 ⇒ f(x) = 500 (0.67)³ = 150.3815

Part B :

Here 0.67 is the decay rate.

That is the rate of decay of the bug is 0.67.

67% of the bugs are decaying with each day.

Part C :

Percent of bugs remaining each day = 100% - 67% = 33%

Part D:

f(x) < 40

500 (0.67)ˣ < 40

(0.67)ˣ < 40 / 500

(0.67)ˣ < 0.08

Taking logarithms on both sides,

㏒ (0.67)ˣ < ㏒ 0.08

x ㏒ (0.67) < ㏒ 0.08

x (-0.1739) < (-1.0969)

Dividing doth sides by (-0.1739), the sign of inequality changes because of dividing by a negative number.

The best estimate for the perimeter of the triangle will be 23.7 inches.

In Δ ABC ∠B =90° , ∠C = 30° , ∠A = 60° and hypotenuse AC = 10 inches

It has been described in the attachment.

Now, we shall calculate side AB and BC by using Trigonometric Ratios.

Sin 30° = AB / AC

or,  AB = 10 × Sin 30° = 10 × 0.5 = 5 inches

And, Cos 30° = CB / AC

or,CB =  10 × Cos 30° = 10 × 0.866 = 8.66 inches

Now, we calculate the perimeter of the given triangle

The perimeter of the triangle is = AB + BC + CA

                                                     = (5.0 + 8.66 + 10.0 ) inches

Step-by-step explanation:

multiply both equations with factors so that the terms of the targeted variable (in our case x) have the same constant factor. and then we can subtract one equation from the other, abd the variable is eliminated in the result.

in our case the least common multiple of 4 and 9 is 36.

so, we multiply equation 1 by 9, and equation 2 by 4, abd then we subtract

36x - 54y = 90

- 36x + 8y = 28

-------------------------

0 -62y = 62

so, x is "eliminated", and we can solve for y : y = -1.

and then we can use one of the original equations to solve for x.

e.g.

9x + 2×-1 = 7

9x - 2 = 7

9x = 9

x = 1

Answer:

First, we'll need to find the LCM (least common multiple) which, in this case, is 36. Now that we know this, we can get 4x and 9x to be 36x and -36x so that they can cancel out. To do this, we have to multiply Equation 1 by 9 and Equation 2 by -4.

9(4x - 6y = 10) is equivilant to 36x - 54y = 90

-4(9x + 2y = 7) is equivilant to -36x - 8y = -28

Now that we have our new system of equations, we can proceed with the process of elimination! The first step is to add the two equations together. This will result in:

-62y = 62 we have successfully eliminated x!

The last step will be to divide both sides by -62

-62y/-62 = 62/-62

y = -1

What is the Pythagorean theorem?

The Pythagorean theorem is a fundamental result in mathematics that states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides (the legs). It is named after the ancient Greek mathematician Pythagoras, who by tradition is credited with its discovery and proof, although it is often argued that it is knowledge that was already known to the ancient Babylonians and Indians.

The theorem can be written mathematically as:

c^2 = a^2 + b^2

This is a classic problem in trigonometry known as the Pythagorean theorem in a right triangle. Since BD is perpendicular to AC, we can use the Pythagorean theorem to find the length of BD, which states that in a right triangle, the square of the length of the hypotenuse (BD in this case) is equal to the sum of the squares of the other two sides (AB and AD).

So, BD^2 = AB^2 + AD^2

We are given that AB = 17cm and AD = 15cm, so we can substitute those values into the equation and solve for BD:

BD^2 = (17cm)^2 + (15cm)^2 = 289 + 225 = 514

To find the length of BD, we take the square root of both sides:

BD = √514cm

BD ≈ 22.67cm

Hence, the length of BD is approximately 22.67cm.
