Answer:

28.278ft^2

Step-by-step explanation:

Given data

Diameter of painting= 6ft

Radius= 3ft

Let us find the area of the painting

Area= πr^2

Substitute

Area= 3.142*3^2

Area= 3.142*9

Area= 28.278ft^2

Answer:

x = 4

y = 13

Step-by-step explanation:

x + y = 17

y = 2x + 5

substitute for y:

x + (2x + 5) = 17

reduce:

3x + 5 = 17

subtract 5 from each side:

3x = 12

divide both sides by 3:

x = 4

y = 2(4) + 5

y = 13

Step-by-step explanation:

Answer:

120

Step-by-step explanation:

First we can find the value of each exterior angle

The sum  of the exterior angles is 360

because a hexagon has 6 congruent exterior angles we divide 360 by 6

360/6=60 so each exterior angle is equal to 60 degrees

the exterior angle and interior angles of any regular polygon are supplementary angles ( meaning the sum of the two is 180) so to calculate the interior angle we subtract 60 from 180

180-60=120 so each measure of the interior angle of a hexagon is 120 degrees

Answer:

x = square root of 55

x^2 = 8^2 - 3^2

x^2= 64 -9

x = square root of 55

Answer:

Step-by-step explanation:

Answer:

angle 1 = 51 degrees

angle 2 = 18 degrees

angle 3 = 123 degrees

angle 4 = 39 degrees

Step-by-step explanation:

angle 2 = 90-72 = 18

angle 3 = 180 - 57 = 123

angle 4 = 180 - 123 - 18 = 39

angle 1 = 90 - 39 = 51

You need to know all the conversion factors.

Hi!

Let's first expand the cotangent of theta.

You'll probably know that tangent will be "y/x", or [tex]\frac{sin(x)}{cos(x)}[/tex], and cotangent is the reciprocal of this, meaning that it is "x/y" or [tex]\frac{cos(x)}{sin(x)}[/tex].

That means that we are now given this equation.

[tex]cos(x)\frac{cos(x)}{sin(x)}+sin(x)[/tex]

That'll multiply to:

[tex]\frac{cos^2(x)}{sin(x)}+sin(x)[/tex]

We'll want a common denominator to add by multiplying [tex]sin(x)[/tex] to both top and bottom of the second term:

[tex]\frac{cos^2(x)}{sin(x)}+\frac{sin^2(x)}{sin(x)}[/tex]

[tex]\frac{cos^2(x)+sin^2(x)}{sin(x)}[/tex]

Pythagorean Identity states that [tex]sin^2(x)+cos^2(x)=1[/tex], so substitute that in:

[tex]\frac{1}{sin(x)}[/tex]

Which simplifies to:

[tex]csc(x)[/tex]

Hope this helps!

Answer:

$13

Step-by-step explanation:

First, you must find out how much Jason's family is spending on admission and keychains. To find this out, just multiply the $10 and the $2 separately by 4. Once you find out how much the family is spending on each item, add them up. It should look like this:

$10 x 4 = $40

$2 x 4 = $8

$40 + $8 = $48

Next, just subtract the $48 from the initial $100 to find out how much the family as a whole can spend on food.

$100 - $48 = $52

Finally, just divide the $52 by 4 to represent how much each family member can spend.

$52 / 4 = $13

Each person in Jason's family can spend $13 on food. Hope this helps!

Answer:

Step-by-step explanation:

5x = 2x +9

3x = +9

x = 3

AB= 5(3)= 15

BC = 2(5) + 9=10 +9=19

AC = 15 + 19 = 34

Answer:

100 ÷ 100 + 12 + 1000= 1013

Step-by-step explanation:

hope it helps

Answer:

1,013

Step-by-step explanation:

we will divide 100 from 100 then the ans will be 1 and then we will add 12 with it so the ans will be 13 and the we will add 1000 with 13 so the and will be

1013

Answer:

41.67πunits³

Step-by-step explanation:

Since we are not asked what to find, we can as well  look for the volume of the cone.

Find the diagram of the cone attached

Volume of the cone = 1/3πr²h

h is the height of the cone

r is the radius of the cone

Volume of the cone = 1/3π(5)²(5)

Volume of the cone= 1/3π(125)

Volume of the cone = 125π/3

Volume of the cone = 41.67πunits³

Answer:

The total cost of the tablet is $840

Step-by-step explanation:

Here, we want to calculate the total cost

Let the total cost be $x

From the ratio, the total ratio is 3 + 4 + 1 = 8

so,;

3/8 * x = 315

3x = 8 * 315

x = 8/3 * 315

x = 8 * 103

x = 840

Answer:

x= -3

Step-by-step explanation:

-5x+3=18

-3 on both sides

-5x=15

divide by -5 on both sides

x= -3

Answer:

X= -3

Step-by-step explanation:

-5x+3=18 subtract 3 from both sides this removes the +3 from the left side and makes the 18 into 15

-5x=15 Divide both sides by -5

x=-3

There is not enough information to find the amount of boys in choir. You did not give us how many girls there are in choir or how many people were in choir in total. That could've helped us. Better luck next time!!!!!

Answer:

x = 60°

y = 72°

z = 48°

Step-by-step explanation:

x = 180 - p = 180 - 120 = 60

Since y;z = 3:2 ,   2y = 3z  or z = 2y/3

Now, x + y + z = 180

60 + y + 2y/3 = 180     Multiply thru by 3 to remove the fraction

180 + 3y + 2y = 540

180 + 5y = 540

5y = 360

y = 72

z = 2(72)/3 = 48

Check:  60 + 72 + 48 = 180

Answer:

x = 3√7

Step-by-step explanation:

The Pythagorean theorem states that in a right triangle, the sum of the legs squared and added together is equal to the hypotenuse (the longest side and the one across the 90° angle)

If the legs are a and b, respectfully, and the hypotenuse is c, the equation would be:

a² + b² = c²

Let's apply this to the problem given.

9² + x² = 12²

Simplify.

81 + x² = 144

Subtract 81 from both sides.

x² = 63

Take the square root.

√(x²) = √63 = √(9 * 7) = √(3² * 7)

x = 3√7

Check the answer.

9² + (3√7)² = 12²

81 + 9 * 7 = 144

81 + 63 = 144

144 = 144

Thus, the answer is correct.

I hope this helps! Feel free to ask any questions! :)
