Step-by-step explanation:

Answer:

904.8 m²

Step-by-step explanation:

needed formulas:

surface of a circle: πr²

circumference of a circle: 2πr

The top and bottom are circles with radius 9, and surface π9² = 81π m²

The side is a rectangle of 2·π·9·7 long, so that is 126π m²

Brings the total to 81π + 81π + 126π = 288π ≈ 904.8 m²

Answer:

4 and 5

Step-by-step explanation:

Let's make an equation to solve. Let's call "one number" x. Another number is 1 more than x, so now we have x + 1. x plus x + 1 is equal to 9... and this gives us our equation:

x + (x + 1) = 9

We can now simplify by adding like terms together:

2x + 1 = 9

Now, let's take away 1 from both sides:

2x = 8

We can finally divide both sides by 2 to isolate x:

x = 4

One of our numbers is 4. Our other number is one more than 4, and 4 + 1 = 5. So our numbers are 4 and 5.

Step-by-step explanation:

[tex] \sf = - \frac{5}{3} + 2 \frac{1}{3} [/tex]

[tex] \sf = 2 \frac{1}{3} - \frac{5}{3} [/tex]

[tex] \sf = \frac{7}{3} - \frac{5}{3} [/tex]

[tex] \sf = \frac{7 - 5}{3} [/tex]

[tex] \sf = \frac{2}{3} [/tex]

Answer:

A = 103°; B = 77°; C = 46°

Step-by-step explanation:

A + 45° + 32° = 180°

A + 77° = 180°

A = 180° - 77°

A = 103°

A + B = 180°

103° + B = 180°

B = 180° - 103°

B = 77°

B + C + 57° = 180°

77° + 57° + C = 180°

134° + C = 180°

C = 180° - 134°

C = 46°

Answer:

Step-by-step explanation:

An ellipse has the general equation

(x/a)² + (y/b)² = 1

(actually, this is an ellipse whose semimajor and -minor axes are parallel to the x- and y-axes, but one can rotate any ellipse so that it has the same configuration, and the area remains constant)

Convert to a kind of rescaled polar coordinates, using

x = a r cos(t)

y = b r sin(t)

Then the interior of such an ellipse is the set

E = {(r, t) : 0 ≤ r ≤ 1 and 0 ≤ t ≤ 2π}

The area of E is then given by the integral

[tex]\displaystyle \iint_E dA[/tex]

Compute the Jacobian determinant for this change of coordinates. The Jacobian is

[tex]J = \begin{bmatrix}x_r & x_t \\ y_r & y_t\end{bmatrix} = \begin{bmatrix}a \cos(t) & -a r \sin(t) \\ b \sin(t) & b r \cos(t)\end{bmatrix}[/tex]

Then we have Jacobian determinant

|det(J)| = |a b r cos²(t) + a b r sin²(t)| = |a b r| = |a b| r

since r ≥ 0.

The area of E is then

[tex]\displaystyle \iint_E dA = \iint_E |ab| r \, dr \, dt[/tex]

[tex]\displaystyle \iint_E dA = \int_0^{2\pi} \int_0^1 |ab| r \, dr \, dt[/tex]

[tex]\displaystyle \iint_E dA = 2\pi |ab| \int_0^1 r \, dr[/tex]

[tex]\displaystyle \iint_E dA = \boxed{\pi |ab|}[/tex]

The grocery bill before the coupons were used was 100 times as much as the bill after the coupons were used.

The grocery bill after the coupons were used was 100 times as much as the bill before the coupons were used.

Answer:

The grocery bill before the coupons were used was 10 times as much as the bill after the coupons were used.

Answer:

Slope = - 3

Step-by-step explanation:

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

( x1, y1 ) = ( - 1, 4 )

Here,

x1 = - 1

y1 = 4

( x2, y2 ) = ( 1, - 2 )

Here,

x2 = 1

y2 = - 2

Slope = ( - 2 - 4 ) / ( 1 - ( - 1 ) )

= - 6 / ( 1 + 1

= - 6 / 2

Slope = - 3

Therefore,

The slope of the line through ( - 1, 4 ) and ( 1, - 2 )

is - 3.

[tex] \frac{4.8}{1 \frac{7}{9} } = (1.2b) \div 6 \frac{2}{3} [/tex]

[tex] \frac{ \frac{48}{10} }{ \frac{16}{9} } = \frac{12b}{10} \div \frac{20}{3} [/tex]

[tex] \frac{48 \times 9}{10 \times 16} = \frac{12b}{10} \times \frac{3}{20} [/tex]
