A poster measuring 150 cm by 180 cm is enlarged in the ratio 5:3. Find the new length and width of the poster.

Answers

Answer 1

The length and width of the new poster are 240 cm and 288 cm, respectively.

What is the new length and width of the poster?

To find the length and breadth of the enlarged poster, we need to multiply the original dimensions by the enlargement ratio.

Let's first find the common ratio between the original poster and the enlarged poster:

Common ratio = Enlarged size / Original size

Common ratio = 5/3

Now, we can find the dimensions of the enlarged/New poster:

Length of enlarged poster = Length of original poster x Common ratio

Length of enlarged poster = 150 cm × 5/3

Length of enlarged poster = 250 cm

Breadth of enlarged poster = Breadth of original poster x Common ratio

Breadth of enlarged poster = 180 cm × 5/3

Breadth of enlarged poster = 300 cm

Therefore, the the dimensions of the new poster is 250cm by 300cm.

Is there anyone who would know how to write this recursive relationship? Also anyone who could write the equation for the second question

Answers

The recursive relationship that describes how the number of Marco's followers is changing each day is Pt = Pt-1 + 32.

It should be noted that after 5 days, Marco will have 597 followers.

How to explain the relationship

The relationship is Pt = Pt-1 + 32 where Pt is the number of followers on day t and Pt-1 is the number of followers on the previous day.

In this case, to calculate how many followers Marco will have after 5 days, we can use this recursive relationship starting with P0 = 437 (the initial number of followers):

P1 = P0 + 32 = 437 + 32 = 469

P2 = P1 + 32 = 469 + 32 = 501

P3 = P2 + 32 = 501 + 32 = 533

P4 = P3 + 32 = 533 + 32 = 565

P5 = P4 + 32 = 565 + 32 = 597

Therefore, after 5 days, Marco will have 597 followers.

The first contestant who creates a single stack using all of their cookies wins a prize! After Bert split all the cookies he had evenly among 4 contestants, each contestant got 24 cookies.
Let c represent how many cookies Bert had to start. Which equation models the problem?
Solve this equation to find how many cookies Bert had to start.
cookies

Answers

The problem states that Bert split all his cookies evenly among 4 contestants, so the total number of cookies Bert had can be found by multiplying the number of cookies each contestant received by the number of contestants:

4 * 24 = 96

Therefore, Bert had a total of 96 cookies to start with.

We can also write an equation to represent the problem, where c represents the number of cookies Bert had to start with:

c / 4 = 24

This equation states that the number of cookies Bert had divided by the number of contestants (4) is equal to the number of cookies each contestant received (24).

To solve for c, we can multiply both sides of the equation by 4:

c = 4 * 24

c = 96

So the solution confirms that Bert had 96 cookies to start with.

C/4=24 so 4*24= 96.

a) What is the unit rate for cups of milk per muffin?

b) What is the unit rate for muffins per cup of milk?

Answers

a) The unit rate for cups of milk per muffin is 1/18 cup of milk per muffin.

b) The unit rate for muffins per cup of milk is 18 muffins per cup of milk.

What are the muffins?

(a) To find the unit rate for cups of milk per muffin, we need to divide the total amount of milk by the number of muffins:

2/3 cup of milk / 12 muffins = (2/3) ÷ 12 cup of milk per muffin

We can simplify this fraction by multiplying the numerator and denominator by 3:

(2/3) ÷ 12 = 2 ÷ (3 x 12) = 2 ÷ 36 = 1/18

So the unit rate for cups of milk per muffin is 1/18 cup of milk per muffin.

b) To find the unit rate for muffins per cup of milk, we need to divide the number of muffins by the total amount of milk:

12 muffins / (2/3 cup of milk) = 12 ÷ (2/3) muffins per cup of milk

To divide by a fraction, we can multiply by its reciprocal:

12 ÷ (2/3) = 12 x (3/2) = 36/2 = 18

So the unit rate for muffins per cup of milk is 18 muffins per cup of milk.

A muffin is a type of small, individual-sized baked good that is usually round in shape and has a slightly sweet taste.

PLEASE LOOK AT THE PICTURE!!!!!!!!!!!!!!!

Answers

The signs of the coordinates of ΔS'T'U' the x-coordinate is positive and the y-coordinate is negative.

What is coordinate?

Coordinates are a set of numbers or values that define the position of a point or object in space or on a surface. They are used to locate a point or object in a specific location relative to a reference point, axis, or plane.

According to question:

The coordinate system is divided into four quadrants, numbered from I to IV, which are separated by the x- and y-axes. The origin is located at the intersection of the x- and y-axes, and has coordinates (0, 0)

The ΔSTU lies in Q3 if it reflected then ΔS'T'U' lies in Q4, it means that the point is located in the fourth quadrant of the Cartesian coordinate system. In this quadrant, the x-coordinates are positive and the y-coordinates are negative.

More specifically, if we assume that the point ΔS'T'U' is represented by the coordinates (x, y), then we have:

x > 0 (because it lies to the right of the y-axis)

y < 0 (because it lies below the x-axis)

For example, if the point ΔS'T'U' has coordinates (3, -2), then it lies in Q4, since the x-coordinate is positive and the y-coordinate is negative.

Part A: Given the function g(x) = |x − 7|, describe the graph of the function, including the vertex, domain, and range. (5 points)

Part B: If the parent function f(x) = |x| is transformed to h(x) = |x| + 2, what transformation occurs from f(x) to h(x)? How are the vertex and range of h(x) affected?

Answers

Part A:

The required graph of the function is described.

The vertex of the function is (7,0)

The domain is : (-∝ , ∝) and

The range is : [0,∝), {yIy ≥ 0}

Part B:

The transformation which occurs from f(x) to h(x) is a vertical shift up to 2 units.

Define functions?

Expressions separated by an equal sign are functions. Both dependent and independent variables are present.

Given Part A:

given the function is g(x) = I x - 7 I

hence from the function, vertex = (h,k)

h = 7 and k = 0

(h,k) = (7,0)

Find the domain by finding where the function is defined.

therefore, domain =  (-∝ , ∝) , where {xIx ∈ R}

The range is the set of values that corresponds with the domain.

therefore, range =  [0,∝), {yIy ≥ 0}

Part B:

given the parent function is:  f(x) = |x|

which is transformed to h(x) = |x| + 2

To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x axis or y axis, and if there is a vertical stretch.

Parent function = f(x) = |x|

Horizontal shift = none

Vertical shift = up 2 units.

Reflection about the x axis = none

hence from the function we can determine the vertex (h,k)

= (0,2)

Find the domain by finding where the function is defined.

therefore, domain =  (-∝ , ∝) , where {xIx ∈ R}

The range is the set of values that corresponds with the domain.

therefore, range = [2,∝) ,  {yIy ≥ 2}

Hence, we get the required answers.

Answers

To find the length and width of each room on the blueprint, we need to use the given scale of 1 in. : 4 ft. This means that every 1 inch on the blueprint represents 4 feet in the actual house.

To find the length and width of each room on the blueprint, we can multiply the actual length and width of each room by 1/4 (or divide by 4). This gives us:

Living room: Length = 12 ft. ÷ 4 = 3 in., Width = 8 ft. ÷ 4 = 2 in.

Kitchen: Length = 16 ft. ÷ 4 = 4 in., Width = 16 ft. ÷ 4 = 4 in.

Office: Length = 16 ft. ÷ 4 = 4 in., Width = 8 ft. ÷ 4 = 2 in.

Bedroom: Length = 20 ft. ÷ 4 = 5 in., Width = 20 ft. ÷ 4 = 5 in.

Bedroom: Length = 10 ft. ÷ 4 = 2.5 in., Width = 20 ft. ÷ 4 = 5 in.

Bathroom: Length = 16 ft. ÷ 4 = 4 in., Width = 8 ft. ÷ 4 = 2 in.

Therefore, the length and width of each room on the blueprint are:

Living room: 3 in. x 2 in.

Kitchen: 4 in. x 4 in.

Office: 4 in. x 2 in.

Bedroom: 5 in. x 5 in.

What is logarithms?

Logarithms are mathematical functions that are used to solve equations involving exponents. Specifically, a logarithm is the inverse operation of exponentiation. Just as exponentiation involves raising a base to a power, logarithms involve finding the power to which a base must be raised to produce a given value.

The logarithm of a number y with respect to a base b is written as logb y, and it is defined as the exponent to which the base b must be raised to produce the number y. In other words, if [tex]b^x = y[/tex], then logb y = x.

According to the question:
In Exercise 36(a), we found that the value of a dollar decreases by 26% over 5 years. We can use this information to answer the following questions:

(a) To estimate the cost of the same house in 10 years, we need to solve the equation:

0.74t = 105,000

where t is the time in years. Solving for t, we get:

[tex]t = log(105,000) / log(0.74) = 17.9[/tex]

So it will take approximately 17.9 years for the value of the dollar to decrease by 26% enough to make the $105,000 house cost the same as it does today. Therefore, we can estimate the cost of the same house in 10 years to be:

[tex]$105,000 * (1 / 0.74)^(10/17.9) = $211,775.22[/tex]

(b) To estimate the cost of a $50 textbook in 8 years, we need to find the value of k in the exponential function:

[tex]V(t) = V(0) * e^kt[/tex]

where V(0) is the initial value (in this case, $50), t is the time in years, and V(t) is the value after t years. We know that the value of a dollar decreases by 26% over 5 years, so we can use this information to find k:

[tex]0.74 = e^(k*5)[/tex]

Taking the natural logarithm of both sides, we get:

ln(0.74) = 5k

Solving for k, we get:

k ≈ -0.064

So the exponential function for the value of a dollar over time is:

[tex]V(t) = $50 * e^{-0.064t}[/tex]

To estimate the cost of the textbook in 8 years, we can plug in t = 8 into this function and solve:

[tex]V(8) = $50 * e^{-0.064*8} = $32.78[/tex]

Therefore, we can estimate the cost of a $50 textbook in 8 years to be approximately $32.78.

4. The value of (1+2+3+...+20) is 210. What is the value of (3+6+9+...+57)?
B) 630
A) 627
C) 570
D) 573
E) 580

Answers

By using sum of sequence the value of (3+6+9+...+57) is 570, which is option C).

What is sum of the sequence ?

The sum of a sequence is the total result of adding up all the numbers in the sequence. The method for finding the sum of a sequence depends on whether the sequence is arithmetic or geometric.

For an arithmetic sequence, in which each term is obtained by adding a fixed number (called the common difference) to the previous term, the sum of the first n terms can be found using the formula:

[tex]Sn = n/2(2a + (n-1)d)[/tex]

where a is the first term, d is the common difference, and n is the number of terms.

For a geometric sequence, in which each term is obtained by multiplying the previous term by a fixed number (called the common ratio), the sum of the first n terms can be found using the formula:

[tex]Sn = a(1-r^n) / (1-r)[/tex]

where a is the first term, r is the common ratio, and n is the number of terms.


According to the question:
We can notice that each number in the sequence 3, 6, 9, ..., 57 is 3 times the corresponding number in the sequence 1, 2, 3, ..., 19.

So, we can find the sum of the sequence 3, 6, 9, ..., 57 by finding the sum of the sequence 1, 2, 3, ..., 19 and then multiplying by 3.

The sum of the sequence 1, 2, 3, ..., 19 is:

1 + 2 + 3 + ... + 19 = (19/2)(1 + 19)/2 = 190

Multiplying by 3, we get:

3 + 6 + 9 + ... + 57 = 3(1 + 2 + 3 + ... + 19) = 3(190) = 570

Therefore, the value of (3+6+9+...+57) is 570, which is option C).

The number of students in the tutoring center was recorded for 40 randomly selected times. The data is summarized in the frequency table below. Number of Students Frequency 0 – 1 15 2 – 3 1 4 – 5 14 6 – 7 2 8 – 9 8 What is the class width for this Frequency Distribution Table?

Answers

After answering the presented question, we can conclude that As a range result, the class breadth in this frequency distribution table is one.

What is range?

The variable's range is calculated by taking its maximum observed value and subtracting its minimum observed value (minimum). Possible range or variational bounds: a variety of steel costs; a variety of styles; The scope or magnitude of a method or action: perception. The maximum or anticipated range of a weapon's projectile. A list or set's range is the number between the lowest and maximum. Align all of the numbers before identifying the region. Next, subtract (reduce) the lowest number from the highest number. The solution includes the range of the list. The solution specifies the range of the list.

To calculate the class width, we must first determine the range of values within each class interval.

The class intervals are as follows:

[tex]0-1\s2-3\s4-5\s6-7[/tex]

8-9

0-1 interval range: 1-0 = 1

2-3 interval range: 3-2 = 1

5-4 = 1 interval range of 4-5

7-6 = 1 interval range of 6-7

8-9 interval range: 9-8 = 1

The intervals all have the same range of one.

To calculate the class width, subtract the upper limit of the first interval from the lower limit of the first interval.

Higher limit of first interval - Lower limit of first interval = class width

1 - 0 class width

1 class width

As a result, the class breadth in this frequency distribution table is one.
