What’s the correct answer for this?

Answer:

a. area of the football field = 40ײ + 240x + 200 ft²

b. area = 57600  ft²

Step-by-step explanation:

The football field is rectangular in shape . Therefore, the area of the football field is the product of length and width.

length = 10x + 10

width = 4x + 20

area of the football field = (10x + 10)(4x + 20)

area of the football field = 40ײ + 200x + 40x + 200

area of the football field = 40ײ + 240x + 200

The standard form polynomial simply implies that the terms are ordered from the largest exponent to the smallest exponent. Therefore the standard form will be  

area of the football field = 40ײ + 240x + 200 ft²

b. area of the football field when width is 160 ft.

The width of the field = 4x + 20. Therefore

160 = 4x + 20

4x = 160 - 20

4x = 140

divide both sides by 4

x = 140/4

x = 35

area = length × width

area = (10x + 10) × 160

where

x = 35

area = (350 + 10) × 160

area = 360 × 160

area = 57600  ft²

a. area of the football field = 40ײ + 240x + 200 ft²

b. area = 57600  ft²

length = 10x + 10

width = 4x + 20

So,

area of the football field = (10x + 10)(4x + 20)

= 40ײ + 200x + 40x + 200

= 40ײ + 240x + 200

b. area of the football field when width is 160 ft.

The width of the field = 4x + 20.

So,

160 = 4x + 20

4x = 160 - 20

4x = 140

x = 35

area = length × width

= (10x + 10) × 160

= (350 + 10) × 160

= 360 × 160

= 57600  ft²

Answer:

Patel’s initial deposit was $3000

Step-by-step explanation:

Given:

Simple interest (S.I.) = 5%

Time period (t) = 10 years

Interest earned (r) = $1500

To find: Patel’s initial deposit

Solution:

Simple interest is a method of calculating the interest charged on the principal, or original amount of a loan.

Let p denotes original amount of a loan

[tex]S.I.=\frac{p\times r\times t}{100}\\\Rightarrow 1500=\frac{p\times 5\times 10}{100}\\\Rightarrow p=\frac{1500\times 100}{5\times 10}\\=3000[/tex]

So, Patel’s initial deposit was $3000

it shows many numbers.

2t = 4 [simplify]

divide both sides by 2

2t/2 = 4/2

so t = 2, but i see that theres a 9 on b? is that an accident?

Answer:

[tex]\sin{65\º}\cos{25\º} + \sin{25\º}\cos{65\º} = \sin{65\º + 25\º} = \sin{90\º} = \sin{\frac{\pi}{2}} = 1[/tex]

Step-by-step explanation:

We use trigonometric identities to solve this question:

[tex]\sin{A + B} = \sin{A}\cos{B} + \sin{B}\cos{A}[/tex]

In this problem:

We have the right side of the equality, that is:

[tex]\sin{65\º}\cos{25\º} + \sin{25\º}\cos{65\º} = \sin{A}\cos{B} + \sin{B}\cos{A}[/tex]

Which means that [tex]A = 65\º, B = 25\º[/tex]

Then

[tex]\sin{65\º}\cos{25\º} + \sin{25\º}\cos{65\º} = \sin{65\º + 25\º} = \sin{90\º} = \sin{\frac{\pi}{2}} = 1[/tex]

Answer:

The new median would be 15.

Step-by-step explanation:

This is because the median means the middle number so we can cross out 2 and 25. Then cross out 6 and 23. Then cross out 7 and 21. Next, cross out 14 and 20. Since there is only one number left, 15, that number is therefore the median.

Answer:

List the numbers in order including 25

2,6,7,14,15,20,21,23,25

choose the number in the middle

15 has 4 numbers to the left and right so it is in the middle so it is the median

Answer:

n =2

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

In this question:

The money is compounded every 6 months.

n is the number of times that interest is compounded per year.

Each 6 months means 12/6 = twice a year. So n =2..

Answer:

s= the customer buy a shirt

p= the customer buy pants

[tex] p(s) = 0.55, p(p) = 0.25 , p(s \cap p) =0.20[/tex]

And we want to find this probability:

[tex] p(s \cup p) [/tex]

And we can use the definition of total probability and we have:

[tex] p(s \cup p) = p(s) +p(p) -p(s \cap p)[/tex]

And replacing we got:

[tex] p(s \cup p) = 0.55+0.25 -0.20 = 0.60[/tex]

And the best answer for this case is:

B. 0.60

Step-by-step explanation:

For this case we can define the following events:

s= the customer buy a shirt

p= the customer buy pants

And we have the following probabilities given:

[tex] p(s) = 0.55, p(p) = 0.25 , p(s \cap p) =0.20[/tex]

And we want to find this probability:

[tex] p(s \cup p) [/tex]

And we can use the definition of total probability and we have:

[tex] p(s \cup p) = p(s) +p(p) -p(s \cap p)[/tex]

And replacing we got:

[tex] p(s \cup p) = 0.55+0.25 -0.20 = 0.60[/tex]

Answer:

The area of the shape is [tex]A=886 \:cm^2[/tex].

Step-by-step explanation:

The shape in the graph is a composite figure is made up of several simple geometric figures such as triangles, and rectangles.

Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.

To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together.

First  separate the composite shape into three simpler shapes, in this case two rectangles and  a triangle. Then find the area of each figure.

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

The area of the first rectangle is [tex]A=34\cdot 16=544\:cm^2[/tex]

The area of the second rectangle is [tex]A=11\cdot19=209\: cm^2[/tex]

The area of a triangle is given by the formula [tex]A=\frac{1}{2} bh[/tex] where b is the base and h is the height of the triangle.

The area of the triangle is [tex]A=\frac{1}{2} \cdot 14\cdot19=133\:cm^2[/tex]

Finally, add the areas of the simpler figures together to find the total area of the  composite figure.

[tex]A_{composite\:shape}=544+209+133=886 \:cm^2[/tex]
