the perimeter P. of any rectangle is given by the formula P = 21 + 2w, where I represents the length if the rectangle and w represents the width. let the length of a rectangle equal 3 ft more than 3 times its width and the perimeter equal 54 ft

Answers

Answer 1

Answer:

width = 6 ft

length = 21 ft

Step-by-step explanation:

Forming algebraic expressions and finding the dimensions of a rectangle:

 Width = w ft

 length =  3*w + 3 = (3w + 3) ft

              2l +2w = P

 2(3w + 3) + 2w = 54

Use distributive property to open the brackets,

 2*3w + 2*3 + 2w = 54

        6w + 6 + 2w = 54

Combine like terms,

          6w + 2w + 6 = 54

               8w   + 6   = 54

Subtract 6 from both sides,

                      8w    = 54 - 6

                         8w = 48

Divide both sides by 8

                           w = 48 ÷ 8

                           [tex]\sf \boxed{\bf w = 6 \ ft}[/tex]

l = 3w + 3

 = 3*6 + 3

 = 18 + 3

l = 21 ft

The coordinates of triangle MNP and triangle QRS are shown in the table.

Q(–2, -5) R(–6, -4) S(–6, -8)

Which BEST describes the relationship, in terms of congruency, between triangle MNP and triangle QRS?

Answers

Using translation concepts, it is found that the triangles are congruent, as triangle QRS is the result triangle after a 180º rotation about the origin of triangle MNP.

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis, or rotations of a degree measure around the origin.

From the vertices of the triangles MNP and QRS, the following transformation was applied:

(x,y) -> (-x,-y).

Which is a 180º rotation about the origin, that is, triangle QRS is the result triangle after a 180º rotation about the origin of triangle MNP.

Rotations do not change the side lengths, only the orientation of the triangle, hence the triangles QRS and MNP are congruent.

1-131. Lindsay has a paper bag full of Fruiti Tutti Chews in three different fruit flavors. She says, “If you reach into the bag, you have a chance of pulling out a Killer Kiwi. There is a chance that you will get Crazy Coconut.”

Answers

The probability of choosing a Kiwi or a coconut  is 14/15.

There has to be another flavor in the bag. The probability of picking the third flavor is 1/15.

There can be 15 candies in the bag. There can be more than one possibility.

What is the probability?

Probability calculates the odds that a random event would occur. The odds that the random event happens lie between 0 and 1. The more likely the event is to occur, the closer the probability value is to 1. If the probability value is 0.5, it is equally likely and unlikely that the event would happen or not happen. The sum of all probabilities should add up to 1.

The probability of choosing a Kiwi or a coconut = chances of picking a kiwi + chances of picking a coconut

1/3 + 3/5

(5 + 9) / 15 = 14/15

There has to be another flavor in the bag because the sum of the probabilities of picking a coconut or a kiwi does not add up to 1.

The probability of getting another flavor = 1 - sum of the probabilities of picking a kiwi or a coconut

1 - 14/15

15/15  - 14/15 = 1/15

The total number of candies in the bag would be a multiple of 15. The multiple of a number is the product of the number and another number. The possible number of candies are 15, 30, 45, 60, 75, 90

Consider the line y=
1
2x+2.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?

Answers

If the equation of a line is [y = (12x + 2)], then the slope of a line parallel to this line will be (Tan θ = 12) and, slope of a line perpendicular to this line will be [Tan θ = [tex](\frac{-1\1}{12})[/tex]].

As per question statement, the equation of a line is [y = (12x + 2)].

We are required to find out the slope of a line parallel to this line and the slope of a line perpendicular to this line.

To solve this question, firstly, we need to know about the standard equation of a line which goes as [tex][y = (mx +c)][/tex] where, "m" is the slope of the line and "c" is the y-intercept.

Comparing our given equation [tex][y = (12x +2)][/tex] with the above mentioned standard equation of [tex][y = (mx +c)][/tex], we get (m = 12) and (c = 2).

Hence, slope of our concerned line is 12. And since slopes of all parallel lines are equal, therefore, the slope of any line parallel to the line [tex][y = (12x +2)][/tex] will be 12 or (Tan θ = 12).

Also, we know that, the product of the slopes of two perpendicular lines, (say m₁ and m₂) is equal to (-1), i.e., [m₁*m₂ = (-1)].

Therefore, the line perpendicular to [tex][y = (12x +2)][/tex] will have a slope of [tex](\frac{-1}{m})[/tex], i.e., ([tex]\frac{-1}{12}[/tex]).

Equation: An equation is a mathematical statement that consists of two separate expressions, connected by an equal signSlope: Slope of a line is defined as the inclination of the line along the positive (x- axis) and is calculated by the formula [tex][m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}} ][/tex] where (x₁, y₁) and (x₂, y₂) are two points on the line.

Explanation:

Consider 2 stocks that either go up, down, or stay unchanged. We'd have a 3 by 3 table to show the 3*3 = 3^2 = 9 different outcomes.

This idea can be extended to 3 stocks to have 3*3*3 = 3^3 = 27 outcomes

4 stocks would have 3^4 = 81 outcomes and so on

Therefore, 9 stocks have 3^9 = 19683 outcomes

You buy a carton of milk and two sandwiches for $10.One sandwich costs twice as much as a carton of milk.Your friend buys two cartons of milk and three sandwiches. How much does your friend spend?

Answers

The total amount spent by your friend is $8

How to determine the amount spent by your friend?

The given parameters are:

1 carton of milk and 2 sandwiches= $10The cost of 1 sandwich = Twice carton of milk

Represent sandwich with x and carton of milk with y

So, we have

x = 2y

This also means that

y + 2x = 10

Substitute x = 2y in y + 2x = 10

y + 2(2y) = 10

This gives

5y = 10

Divide by 2

y = 2

Recall that:

x = 2y

So, we have

x =2 * 1

x = 2

Your friend's purchase can be represented as:

​c) Find the year when the record will be sec.

Answers

The year will be 2018, the predicted record of 43.74

1920, the record for a certain race was 45.9 sec.

In 1950, it was 45.0 sec.

Let R(t)= the record in the race and t= the number of years since 1920.

How to calculate slope

The equation of slope of any line can be calculated using the following formula, m = rise/run = tanθ = Δy/Δx = (y2 - y1)/(x2 - x1) where, m is the slope. Δy is the change in y-coordinates.

slope = (45-45.9)/30 = -0.9/30 = -0.03

EQUATION:

R(t)= -0.03t + 45.9

b) The predicted record for 2003

t = 83 in 2003

R(83) = -0.03*83 + 45.9

R(83) = 43.41

The predicted record for 2006

t = 86 in 2006

R(86) = -0.03*86 + 45.9

R(86) = 43.32

C) Solve for t

-.02t + 45.7 = 43.74

-.02t = 43.74 - 45.7

-.02t = -1.96

t = +98

1920 + 98 = 2018, the predicted record of 43.74

This type of equations are called linear equations

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it.
