Answer: 1. 27/72 = 3/8,  2. 24/40 = 3/5,  3. 6/42 = 1/7

Step-by-step explanation:

1. 27/72 divided by 9/9 equals 3/8.

2. 24/40 divided by 8/8 equals 3/5.

3. 6/42 divided by 6/6 equals 1/7.

The total length of the bolt should be 21/8 inches.

The study and application of numbers in all other fields of mathematics are covered in the area of mathematics known as arithmetic operations. Addition, subtraction, multiplication, and division are included in the basic operations.

Given the thickness of plate 1 = 7/8 inches

the thickness of plate 2 = [tex]1\frac{1}{4}[/tex] inches = 5/8 inches

total thickness of both plates = 7/8 + 5/4

5/4 is equaivalent to (5*2)/(4*2) = 10/8

the total thickness of both plates = 7/8 + 10/8

the total thickness of both plates = 17/8 inches

and the bolt must be at least 1/2 inch longer

total length of bolt = 17/8 + 1/2

convert 1/2 to the same denominator as 17/8

1/2 = (1*4)/(2*4) = 4/8

total length of bolt = 17/8 + 4/8

the total length of the bolt =  21/8 inches

Hence the bolt should be 21/8 inches longer.

Step-by-step explanation:

The m∠1 and m∠2 which are linear pairs of angles are 72° and 108°.

We know when a transversal intersects two parallel lines at two distinct points,

Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.

We know that the sum of linear pair of angles is equal to 180°.

therefore, From the given information, (x + 36)° + 3x° = 180°.

4x + 36° = 180°.

4x = 144°.

x = 36°.

So, m∠1 = 72° and m∠2 = 108°.

Answer:

150 units (Option C)

Step-by-step explanation:

Perimeter of rectangle = Perimeter of triangle

= {2 × (Length + Width)} = Sum of all three sides

= {2 × [(2x) + (x + 12)]} = [(4x) + (2x) + (x + 3)]

The parenthesis are expanded using the Distributive Law:
= {2 × [2x + x + 12]}  = [4x + 2x + x + 3]

= {2 × [3x + 12]} = [7x + 3]
= 6x + 24 = 7x + 3

Bring all the like terms together and isolate x:

= 24 - 3 = 7x - 6x

= 21 = x

∴x = 21

Substitute this calculated value of x to determine the perimeter of rectangle:

6x + 24

= 6(21) + 24

= 126 + 24

= 150 units

∴Option C

The length of line in an ordered pair is calculated using the formula

d = √{(x₂ - x₁)² + (y₂ - y₁)²}

where

d = distance between the points

x₂ and x₁ = points in x coordinates

y₂ and y₁ = points in y coordinates

distance between points  (-1, 1) and (-1,, y) is calculated to be 50 yards and hence we solve for y

d = √{(x₂ - x₁)² + (y₂ - y₁)²}

50 =√{(-1 - -1)² + (1 - y)²}

50 =√{ (1 - y)²}

2500 = (1 - y) (1 - y)

2500 = 1 - 2y + y²

[tex]\cos \theta=\dfrac{2}{3}[/tex]

[tex]\sin \theta=-\dfrac{\sqrt{5}}{3}[/tex]

Step-by-step explanation:

To find the exact values of the trigonometric functions of θ, we can use the following trigonometric identities:

[tex]\boxed{\begin{minipage}{4 cm}\underline{Trigonometric Identities}\\\\$\sec x=\dfrac{1}{\cos x}$\\\\\\$\tan x=\dfrac{\sin x}{\cos x}$\\\\\\$\sin^2x+\cos^2x=1$\\\end{minipage}}[/tex]

In quadrant IV, cosine of the angle is positive, whereas sine of the angle is negative.

[tex]\sec \theta=\dfrac{3}{2}[/tex]

[tex]\dfrac{1}{\cos \theta}=\dfrac{3}{2}[/tex]

[tex]\boxed{\cos \theta=\dfrac{2}{3}}[/tex]

To find sin θ, we can substitute the found value of cos θ into the Pythagorean identity:

Answer:

Length = 10cm, Width = 9 cm

Step-by-step explanation:

Let's call the amount that both the length and width are increased by "x". So, the new length is 5 + x and the new width is 4 + x.

The original area of the rectangle was 5 * 4 = 20 cm2.

The new area of the rectangle after the increase is (5 + x) * (4 + x) = 20 + 70 + 2x^2.

Expanding the right-hand side, we have 20 + 70 + 2x^2 = 90 + 2x^2.

Equating the two areas, we get:

20 + 70 + 2x^2 = 90 + 2x^2

Subtracting 2x^2 from both sides:

20 + 70 = 90

Subtracting 20 from both sides:

70 = 70

So x^2 = 50 / 2 = 25.

Taking the square root of both sides, we get:

x = 5

So the length of the longer rectangle is 5 + x = 5 + 5 = 10 cm, and the width is 4 + x = 4 + 5 = 9 cm.

Leonard gave the correct value of approximate average rate of change of function.

What is a function?

In mathematics, a function is an expression, rule, or law that specifies the relationship between an independent variable x and a dependent variable y.

The average rate of change of  function means the typical rate at which one quantity is changing in respect to another. A method that determines the amount of change in one item divided by the corresponding amount of change in another is known as an average rate of change function.

The formula for average rate of change of  function in the interval [a,b] is

[tex]\frac{f(b) - f(a)}{b-a}[/tex].

We are asked to find the rate of change when x = -3 to 6

From graph

when x = -3 , y = -2

when x = 6, y = 2

So average rate of change of function = [tex]\frac{f(6) - f(-3)}{6-(-3)} = \frac{2 - (-2)}{9} = \frac{4}{9}[/tex]

Therefore Leonard gave the correct value of approximate average rate of change of function.

Answer:

A(L) = - L²  + 215L

Domain
0 < L < 215

or

(0, 215) in interval notation

Step-by-step explanation:

Let  L represent the length and W the width

Perimeter of a rectangle = 2(L+W) and is given as 430 meters

Therefore 2(L + W) = 430

L + W = 430/2
L + W = 215

W = 215-L

The area A is given by L x W

Substituting for W in terms of L this becomes

A = L x(215 - L)

A = 215L - L²

which can be expressed as a function of in the form
A(L) = 215L - L² or in standard form(highest degree first)

A(L) = - L²  + 215L

The domain of this function are the values of L which result in a defined , real value for A

Without restrictions, the domain for L is -∞ < L < ∞. However real world facts coming into play

1. Area cannot be zero
So A(L) > 0 (upper bound on area)

-L² + 215L > 0

-L² > - 215L Move 215L to right side

L² < 215L   (dividing by -1 changes signs of variables and also inequality)

L < 215      (divide by L both sides)

2. Length cannot be negative
So lower bound on L is L > 0

Together the domain is
0 < L < 215

The relative speed is the net speed of two different objects with respect to each other.

If two objects move in the same direction we take the difference between their speeds.

If two objects move in the opposite direction we take the sum of their speeds.

We can utilize the following parameters in our calculation based on the question,

Time = 4 pm

Distance = 64 km

Calculate how long it took the father to ride his horse and the son to walk the first 32 miles.

Time = Distance / (Difference between rates of father and son)

Time = 32 km / (8 km/h - 3 km/h)

Time = 32 km / 5 km/h

Time = 6.4 hours

Determine how long it will take the father to walk the final 32 miles and the son to ride the horse.

Time = Distance / (Difference in Speed)

Time = 32 km / (8 km/h - 4 km/h)

Time = 32 km / 4 km/h

Time = 8 hours

Answer: The probability that a customer wins a prize 8.3%

Step-by-step explanation:

First off, the dice has twelve sides and only of the sides, 9, will allow a customer to win.

this means that there is a 1/12 chance that the customer will win a prize.

We can rewrite this into a decimal: 0.0833

and then to a percentage rounded to the nearest tenth: 8.3%

The probability that a customer wins a prize is 8.3% to the nearest tenth.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

A clothing store has each customer roll a 12-sided die with faces numbered 1−12 to win a free T-shirt.

Customers who roll a 9 win.

Total possible outcomes = 12

Number of outcomes which results in a win = 1

Probability that a customer wins = 1/12

                                                       = 0.08333

                                                       = 8.3%
