A man bought a calf for $200 and sold it for
$250. What was his gain as a percentage of the
cost price?​

Answers

Answer:

Step-by-step explanation:

250 is 125% of 200

So,

He gained 25% in profit

Based on the information given his gain as a percentage of the  cost price is 25%.

Using this formula

Cost price percentage=Selling price-Cost price/Cost price

Where:

Selling price=$250

Cost price=$200

Let plug in the formula

Cost price percentage=$250-$200/$200

Cost price percentage=$50/200

Cost price percentage=0.25×100

Cost price percentage=25%

Inconclusion his gain as a percentage of the  cost price is 25%.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

There are 10 seniors and 15 juniors in a gym class.

The total number of students will be given as,

Total students = 10 + 15

Total students = 25

Then the ratio of seniors to total students will be given as,

Ratio = Seniors / Total student

Ratio = 10 / 25

Ratio = 2 / 5

The ratio of seniors to total students will be 2: 5.

Bob and Alice have designed and created a website for their high school. The first week they had 5 visitors to the site; the second week, they had 10 visitors; and during the third week, they had 20 visitors. If the trend continues, how many visitors can they expect in the fifth week? Explain your answer.

Answers

Answer:

80 visitors

Step-by-step explanation:

From the above question, we can see that:

The trend is explained using geometric sequence

The formula for Geometric sequence is given as:

an = ar ^n - 1

Where a = first term

r = common ratio

n = number of terms

an = nth term

From the above question, let the number of term be equal to the number of weeks.

First week = First term = 5

Second week = Second term = 10

Third week = Third term = 20

Common ratio = a2/a1 = a3/a2 = 10/5 = 20/10 = 2

We are to find the number of visitors for the Fifth week = fifth term,

Hence:

a5 = 5 × 2^5 - 1

a5 = 5 × 2^4

a5 = 80 visitors

The number of visitors we can expect for the fifth week = 80 visitors

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that the number of students who bring lunch is 45 fewer these the number of students who eat the school lunch. There are more than 485 students who bring lunch.

The number of students who bring lunch, is;

B > 485 students

The number of student who eat lunch in school, E = B + 45

Thus, E > 485 + 45

The number of student that possibly eat lunch in school, E > 530 students.

The number of students, n that possibly eat lunch at school, n = 531 or more students.

1. Pentagon MNPQR is shown on the coordinate grid. Pentagon MNPQR is dilated with
the origin as the center of dilation using the rule (x, y) - (x, y) to create pentagon
M'N'P'Q'R'. Which statement is true?

Answers

Answer:

B

Step-by-step explanation:

if its less than 1 it shrinks

The correct statement is; Pentagon M’N’P’Q’R is smaller than pentagon MNPQR because the scale factor is smaller than 1.

What is the scale factor?

The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.

If a polygon is dilated by a scale factor = k

Rule to be followed as;

(x, y) → (kx, ky)

Here, k = Scale factor

If 0 < k < 1, size of the image will be reduced.

Similarly, k > 1, size of the image will be enlarged.

We are given that Pentagon MNPQR is dilated with the origin as the center of dilation to form an image M'N'P'Q'R'.

Rule used for the transformation,

(x, y) → (1/4x, 1/4y)

Here, the scale factor through which MNPQR has been dilated is 1/4.

Since, scale factor is between zero and 1/4, size of M'N'P'Q'R' will be reduced.

Therefore, the size of pentagon M'N'P'Q'R' will be 1/4 smaller than pentagon MNPQR.

Option (2) is the answer.
