Answer:

129.89 m²

Step-by-step explanation:

Area of a circle of radius r is A = πr².

If r = 6.43 m, then A = π(6.43 m)²  =  129.89 m²

Answer:

Your answer is 539.93

Step-by-step explanation:

A = pi*r²

A = pi* 13²

A = pi*169

A = 539.93

Answer:

The height is: [tex]h = 51.96cm[/tex]

Step-by-step explanation:

Given

[tex]L = 60m[/tex]

[tex]\theta = 60[/tex]

Required

The height of the kite

See attachment for illustration.

To calculate height (h), we have:

[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]

This gives

[tex]\sin(60) = \frac{h}{60}[/tex]

Make h the subject

[tex]h = 60 * \sin(60)[/tex]

[tex]h = 60 * 0.8660[/tex]

[tex]h = 51.96cm[/tex]

Answer:

5x−4y

Step-by-step explanation:

:D

Answer: 5x - 4y

Step-by-step explanation: combining like terms means to combine the terms that have the same letter. so since the 3 and 2 have an x you combine them and the 3 and -7 have a y you combine them. hope this helped:)

Answer:

$53.33

Step-by-step explanation:

A whole (100%)- 25% is 0.75

x*0.75=40

/0.75 /0.75

x=53.33333

round to the 2 decimal since this is money

Therefore the original sale price was $53.33

Have a nice day and I hope this helped. :D

Answer:

Step-by-step explanation:

standard form = combine like therms and degrees drop from left to right

In this there aren’t like therms, so:

6x^3+x^2-9x+5

therms =  each therm is seprated by a plus or a minus

in this case there are 4 therms

degree = look at the monomial with the highest degree

in this case is 3

Name = in this case there are four therms so it is a quadrinomial

Standard form denotes to arranging according to degrees or exponents

Standard form

Number of terms=4

Degree=3

Name Quadrinomial or Biquadratic

Answer:

part A: 6:25

Step-by-step explanation:

Answer: 385 min. and part b multiply 385 by 60

Step-by-step explanation:

you are welcome

Answer:

T = (m × 20) + 25

(2.5 × 20) + 25 = 75

75 minutes

110 - 25 = 85

85 ÷ 20 = 4.25

4.25 kilograms

Answer:

150.72

Step-by-step explanation:

Area of circle formula is r²π

Do find radius you do d/2, diameter/2. 13/2= 6.5

6.5 * 6.5 = 42.25

π  is also known as 3.14

42.25 * 3.14 = 132.665

That is the area of the smaller one.

For the larger one, 19/2 = 9.5

9.5 * 9.5 = 90.25

90.25 * 3.14= 283.385

Now you subtract both of them and the difference is 150.72.

Hope this helps !!

Answer

150.72 m2

Step-by-step explanation:

Find the radius of the larger

merry-go-round.

19^2 = 9.5

Substitute 9.5 for r in the formula for the

area of a circle.

A-n • 9.52

= 71 -90.25

- 283.385

Find the radius of the smaller

merry-go-round.

13-^-2-6.5

Substitute 6.5 for r in the formula for the

area of a circle.

A~n • 6.52

= n - 42.25

-132.665

Subtract the area of the smaller merry go-round from the area of the larger

merry-go-round.

283.385 - 132.665 = 150.72

Answer: you need more information to solve

Step-by-step explanation:

Answer:

77 this answer is rounded to the nearest tenth

Step-by-step explanation:

The formula for the are of a circle is A=πr² so thats π7² which is equaled to about 153.9 since this is a semicircle you'd divide that by two giving you 76.96902.

Respuesta:

12, 13

Explicación paso a paso:

Dejar,

Número más pequeño = x

Número mayor = x + 1

Expresarse matemáticamente;

2 (x + 1) - (x / 2) = ((x + 1 + x) / 5) + 15

2x + 2 - 0.5x = 0.2 (2x +1) + 15

1.5x + 2 = 0.4x + 0.2 + 15

1.5x - 0.4x = 0.2 + 15 - 2

1,1 veces = 13,2

x = 13,2 / 1,1

x = 12

x + 1 = 12 + 1 = 13

Answer:

  $125

Step-by-step explanation:

For x = 140, the function definition for x ≥ 100 is used.

p(140) = 95 +0.75(140 -100) = 95 +30 = 125

The customer will owe $125 for items with a value of $140.

Answer:

4 pounds divided by 8 as a fraction

4/8 = 1/2

-TheUnknownScientist

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

so 4 divided by 8 can be represented in fraction for like this:

[tex]\frac{4}{8}[/tex] which can be simplified by multiplying the top and bottom by 4:

[tex]\frac{4}{8} = \frac{4 \div 4}{8 \div 4} = \frac{1}{2}[/tex] and that is the answer

Answer:

8 1/8

Step-by-step explanation:

1st I'm going to turn these into improper fractions with a golf swing (multiply the bottom, add the top, keep denominator the same)

3 times 4 + 3 = 15, so we get 15 over 4

4 times 8 + 3 = 35, so we get 35 over 8

Next I am going to give them a common denominator. (Their least common multiple is 8)

one denominator is already 8, so we need to fix the other one by multiplying it by two (multiply both sides)

15/4 times 2/2 = 30/8

Now we add the two fractions (DO NOT ADD DENOMINATORS)

30/8 + 35/8 = 65/8

Finally to make it a mixed number, ask self, how many times does 8 go into 65? 8 times. That's the whole number. what's left over? 1. That is the numerator. The denominator stays the same.

you can use a calculator to try and multiply all of them so multiply 6x4 and then it will give you the answer then once you have that answer multiply it with the 4 im pretty sure but if not then sorry

Answer: Y= 1/8x -2

Step-by-step explanation:

Y = mx+ b

Slope = y2-y1/x2-x1 = -1+2 / 8-0 = 1/8

Initial Y-Value = -2

Answer:

x = 6

y = 13

Step-by-step explanation:

x + y = 19

x - y = -7

To eliminate x, subtract ther second equation from the first

2y = 26

y = 13

To eliminate y, add the equations

2x = 12

x = 6
