a rectangular playing field is 80 yd long and has an area of 4240 yd squared. find the width of the field?​

Answer:

y = -5/2x + 20/3

Step-by-step explanation:

x-int of 3x + 6y = 8

sub 0 for y

3x + 6(0) = 8

3x = 8

x = 8/3 or 2.667

line perpendicular to 2x - 5y = 10

put into y = mx + b form

2x - 5y - 10 = 0

5y = 2x - 10

y = 2/5 x - 2

find negative reciprocal of the slope 2/5 x (for the perpendicular line)

-5/2 x

find the y-int (b)

m = -5/2 x

must pass through (8/3,0)

y = mx + b

0 =  -5/2(8/3) + b

0 = -40/6 + b

b = 20/3

therefor the equation of the line is y = -5/2x + 20/3

Answer:

2014 price was $49,091

Step-by-step explanation:

I'm assuming you want to solve for 2014 year price...

2015 year price is 54,000 and was 10% higher than 2014 price, meaning 2015 price is 110% of 2014 price so...

p×110%=54,000

p=54,000/1.1

p=49,090.90

Answer:

1 cup = 12 biscuits

2 cups = 24 biscuits

3 cups = 36 biscuits

So, 3 cups make 36 biscuits.

Step-by-step explanation:

36 ÷ 12 = 3

Answer:

3 cups of milk

Step-by-step explanation:

1 cup = 12 biscuits

x cups = 36 biscuits

1/12 = x/36

cross multiply

36 = 12x

36/12 = 12x/12

3 = x

Step-by-step explanation:

370.00 plus 150.00 equals to 520.00

520.00 plus another 150.00 equals to 670.00

670.00 plus 100.00 equals to 770.00

770.00 plus 30.00 equals to $800.00 total

Answer: $800 total

Answer: it says had so its $400

Step-by-step explanation:

Its 370+30=400

Step-by-step explanation:

First you find the volume of one cube by doing 1/2*1/2*1/2, after this you times this number by 16 to get the volume of the whole structure

Answer:

12897 square feet

Step-by-step explanation:

So first find the area of the square:  

85 * 85 = 7225

Then, the two semi circles together is a full circle. Use the circle area formula,

A = πr^2

The radius (r) would be half the diameter of the circle. The diameter of the circle would be 85. So half of that is 42.5. The radius is 42.5

Now:

A = π(42.5)^2

A = 3.14(42.5)^2

A = 3.14(1806.25)

A = 5671.625

Lastly, add the two areas up for the square and circle:

7225 + 5671.625 = 12896.625

Round to nearest tenth: 12897

Answer:

404 adult tickets were sold, and 250 child tickets.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that

x is the number of adult tickets sold.

y is the number of child tickets sold.

654 tickets were sold.

This means that

[tex]x + y = 654[/tex]

[tex]y = 654 - x[/tex]

Admission prices at a football game were $5 for adults and $ 2 for children. The total value of the tickets sold was $2520.

This means that

[tex]5x + 2y = 2520[/tex]

Since [tex]y = 654 - x[/tex]

[tex]5x + 2(654 - x) = 2520[/tex]

[tex]5x + 1308 - 2x = 2520[/tex]

[tex]3x = 1212[/tex]

[tex]x = \frac{1212}{3}[/tex]

[tex]x = 404[/tex]

[tex]y = 654 - x = 654 - 404 = 250[/tex]

404 adult tickets were sold, and 250 child tickets.

Answer:

by inscribed angle rule do it.

Step-by-step explanation:

hope this help

Answer:

70°

Step-by-step explanation:

∠ADC is a inscribed angle. ∠ABC is a central angle. The inscribed angle's measurement will be 1/2 of the measurement of the central angle.

In this case, the inscribed angle ∠ADC is given to you with a measurement of 35°. To solve for ∠ABC, multiply 2 to the given value:

35 x 2 = 70

70° is your answer.

Answer:

Step-by-step explanation:

To find:-

Answer:-

We are here given that the value of,

[tex]\longrightarrow \cos\theta=\dfrac{3}{\sqrt{22}} \\[/tex]

And we know that cosine is the ratio of base and hypotenuse. Therefore,

[tex]\longrightarrow \cos\theta =\dfrac{b}{h} \\[/tex]

So we can also say that,

[tex]\longrightarrow \cos\theta = \dfrac{b}{h}=\dfrac{3}{\sqrt{22}}\\[/tex]

Let us take the given ratio to be 3x:√22x . Now we may find out the value of perpendicular using Pythagoras theorem . The Pythagoras theorem is ,

Pythagoras theorem:-

Mathematically,

[tex]\longrightarrow \boxed{ \boldsymbol{p^2+b^2=h^2}} \\[/tex]

where the symbols have their usual meaning.

On substituting the respective values, we have;

[tex]\longrightarrow p^2+(3x)^2=(\sqrt{22}x)^2 \\[/tex]

[tex]\longrightarrow p^2 = 22x^2-9x^2\\[/tex]

[tex]\longrightarrow p^2=13x^2 \\[/tex]

[tex]\longrightarrow \boldsymbol{ p = \sqrt{13}x} \\[/tex]

Now again , we know that, tangent is defined as the ratio of perpendicular and base. Therefore,

[tex]\longrightarrow \tan\theta = \dfrac{p}{b} \\[/tex]

[tex]\longrightarrow \tan\theta = \dfrac{\sqrt{13}x}{3x}\\[/tex]

[tex]\longrightarrow \boldsymbol{ \tan\theta = \dfrac{\sqrt{13}}{3}}\\[/tex]

Now we may use a identity which is ,

[tex]\longrightarrow\boxed{ \boldsymbol{ \tan (2x)= \dfrac{2\tan x}{1-\tan^2 x}}}\\[/tex]

On substituting the respective values, we have;

[tex]\longrightarrow \tan2\theta = \dfrac{ 2\tan\theta}{1- \tan^2\theta}\\[/tex]

[tex]\longrightarrow \tan2\theta = \dfrac{2\bigg(\dfrac{\sqrt{13}}{3}\bigg)}{1-\bigg(\dfrac{\sqrt{13}}{3}\bigg)^2 } \\[/tex]

[tex]\longrightarrow \tan2\theta = \dfrac{\dfrac{2\sqrt{13}}{3}}{1-\dfrac{13}{9}} \\[/tex]

[tex]\longrightarrow \tan2\theta = \dfrac{\dfrac{2\sqrt{13}}{3}}{\dfrac{9-13}{9}} \\[/tex]

[tex]\longrightarrow \tan2\theta = \dfrac{\dfrac{2\sqrt{13}}{3}}{\dfrac{-4}{9}} \\[/tex]

[tex]\longrightarrow \tan2\theta = -\dfrac{2\sqrt{13}\cdot 9}{3\cdot 4 } \\[/tex]

[tex]\longrightarrow \boxed{\boldsymbol{ \tan2\theta = -\dfrac{3\sqrt{13}}{2}}} \\[/tex]

This is the required answer .
