Answer:

220m

Step-by-step explanation:

l=85m

b=25m

perimeter=2(l+b)

2(85+25)

2(110)

=220m

perimeter is 220m

Answer:

Step-by-step explanation:

The distance around the field means the perimeter of the field

Since the field is rectangular

Perimeter of a rectangle = 2l + 2w

where l is the length

w is the width

From the question

l = 85m

w = 25m

Perimeter = 2(85) + 2(25)

Perimeter = 170 + 50

The final answer is

Perimeter = 220m

Answer:

Step-by-step explanation:

Based on the information provided, we can use the following credit score range and corresponding points:

Excellent: 800-850 (23-27 points)

Very good: 750-799 (18-22 points)

Good: 700-749 (13-17 points)

Fair: 650-699 (8-12 points)

Poor: 600-649 (5-7 points)

Bad: below 600 (0-4 points)

Using this range, we can add up the points for Ivan's information:

Age: 23 points (because he is between 60-64 years old)

Time at address: 5 points (because he has lived at his address for more than 10 years)

Age of auto: 5 points (because he has owned his car for 2-4 years)

Car payment: 13 points (because his monthly car payment is between $200-$299)

Housing costs: 23 points (because he owns his home and has no monthly mortgage or rent payment)

Checking and savings accounts: 5 points (because he has both types of accounts)

Finance company reference: 5 points (because he has a reference from a finance company)

Declared bankruptcy: 0 points (because he has never declared bankruptcy)

Adding up all these points, we get a total of 79 points. Based on the credit score range and points listed above, this falls into the "Excellent" category, which corresponds to a credit score between 800-850. Therefore, Ivan's credit score is likely to be in that range.

Answer:

The minimum exam score to be awarded an A is about 8.52.

Step-by-step explanation:

Let X represent the scores on a common final exam.

It is provided that X follows a normal distribution with mean, μ = 71 and standard deviation, σ = 9.

It is provided that according to the department policy is that the top 10% of students receive an A.

That is, P (X > x) = 0.10.

⇒ P (X < x) = 0.90

⇒ P (Z < z) = 0.90

The corresponding z-score is:

z = 1.28

Compute the value of x as follows:

\(z=\frac{x-\mu}{\sigma}\\\\1.28=\frac{x-71}{9}\\\\x=71+(1.28\times 9)\\\\x=82.52\)

Thus, the minimum exam score to be awarded an A is about 8.52.

Answer:

Step-by-step explanation:

red/blue = 3/4 and you get blue/green = 4/5

= 60/4 = 15

you have 15 red shirts, 20 blue shirts, and 25 green shirts.

15/20 = 3/4

20/25 = 4/5

if you simplify 15/20, you will see that it is equivalent to 3/4

if you simplify 20/25, you will see that it is equivalent to 4/5.

Answer:

Step-by-step explanation:

C = 3t - 1 + t^6

D = 2t + 7

2C - 2D

2(3t - 1 + t^6) - 2(2t + 7)

6t -2 + 2t^6 - 4t - 14

2t^6 + 2t - 16

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

C = 3t - 1 + t^6

D = 2t + 7

2C = 2 ( 3t - 1 + \(t^6\) )

2D = 2 (2t + 7)

The expression that equals 2C - 2D is

2t - 16 + 2\(t^6\).

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

C = 3t - 1 + t^6

D = 2t + 7

Now,

2C = 2 ( 3t - 1 + \(t^6\) )

2D = 2 (2t + 7)

Now,

2C - 2D

= 2 ( 3t - 1 + \(t^6\) ) - 2 ( 2t + 7 )

= 6t - 2 + 2\(t^6\) - 4t - 14

= 2t - 16 + 2\(t^6\)

Thus,

C = 3t - 1 + t^6

D = 2t + 7

2C = 2 ( 3t - 1 + \(t^6\) )

2D = 2 (2t + 7)

The expression that equals 2C - 2D is

2t - 16 + 2\(t^6\).

The data in the table can be modeled by this linear equation in slope-intercept form: y = 8x - 5.

The slope is 8, which means the wages earned increases at rate of 8 dollars per hour as the time increases.

The y-intercept is -5 and it represent the initial wages earned.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is represented by this mathematical expression;

y = mx + c

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (24.00 - 8.00)/(3 - 1)

Slope (m) = 16.00/2

Slope (m) = 8

At data point (1, 3), a linear equation in slope-intercept form for this line can be calculated as follows:

y - y₁ = m(x - x₁)

y - 3 = 8(x - 1)

y = 8x - 8 + 3

According to the 90° clockwise rotation, the new coordinate of the quadrilateral D' is (3, -2)

Quadrilateral

Quadrilateral refers a closed shape and a type of polygon that has four sides, four vertices and four angles.

Given,

If quadrilateral ABCD is rotated 90° clockwise about point A and then reflected across the y-axis to create quadrilateral A’B’C’D’.

Here we need to find the coordinate of D'.

In order to find the new coordinates, first we have to identify the current coordinates of the quadrilateral.

While we looking into the graph, we have identify the point of

A (0,0), B(-4, 3), C(1,5) and D(2,3)

Now, we have to use the rule of clockwise 90° rotation, states that to rotate the figure 90 degrees clockwise about a point, every point(x , y) will rotate to (y, -x).

According to this rule, the new coordinates are written as,

A(0,0) = A'(0,0)

B'(-4,3) = B'(-3,-4)

C(1,5) = C'(5, -1)

D(2,3) = D' (3, -2)

Therefore, the new coordinate of D' is (3, -2).

Zales's percent markup on the selling price as required in the task content is; 37.5%.

It follows from the task content that the percent markup on the selling price be determined according to the given data.

Since the cost of diamonds is; $800 while the diamonds sell for $1,100. It follows that the markup on the selling price of the diamonds is;

Markup = Selling price - Cost price.

Hence, we have;

Markup = 1,100 - 800.

Therefore, the markup is; $300.

On this note, the percent markup can be determined as follows;

= (300/800) × 100%.

= 37.5%.
