The area of Krista’s mom new pan is 11 1/4 ft² and two possible dimensions are (5 , 4 1/2) and (4 1/2 , 2 1/2)

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

[tex]A=a\times b[/tex]

Here, (a)is the length of the rectangle and (b) is the width of the rectangle

The dimensions of pan which, Krista’s mom, had planned is 5 feet long by 4 1/2 feet wide. Therefore, the length of the pen is 5 feet and the width of the pan is 4 1/2 feet.

Thus, the area of this rectangular pan is,

[tex]A=5\times4\dfrac{1}{2}\\A=5\times\dfrac{9}{2}\\A=22\dfrac{1}{2}\rm ft^2[/tex]

The area of the pan is 22 1/2 ft².

Now, Krista’s mom has told her she needs to make the pen 1/2 the size. Thus the area of new pan is,

[tex]A=\dfrac{22\dfrac{1}{2}}{2}\\A=\dfrac{\dfrac{45}{2}}{2}\\A=\dfrac{45}{4}}\\A=11\dfrac{1}{4}}\\[/tex]

For this area, possible dimensions are 4 1/2 and 2 1/2.

Hence, the area of Krista’s mom new pan is 11 1/4 ft² and two possible dimensions are (5 , 4 1/2) and (4 1/2 , 2 1/2)

Answer:

i) 134

ii) Number of bottles sold on Tuesday:   [tex]\dfrac{x}{45}[/tex]

iii) Number of bottles sold on Wednesday:  [tex]\dfrac{(x-75)}{48}[/tex]

iv) [tex]x=3915[/tex]

Therefore, 87 bottles were sold on Tuesday and 80 bottles were sold on Wednesday

Step-by-step explanation:

i) You need to ensure that the values are both in the same format (either both in dollars, or both in cents).

45 cents = 45/100 dollars = 0.45 dollars

60.30 ÷ 0.45 = 134

ii) both values are in cents, so no need to convert one of them.

Let n be the number of bottles sold.

So 45n = x

Therefore, n = x/45

ii)

Let n be the number of bottles sold.

So 48n = (x - 75)

Therefore, n = [tex]\dfrac{(x-75)}{48}[/tex]

iv)

Number of bottles sold on Tuesday:   [tex]\dfrac{x}{45}[/tex]

Number of bottles sold on Wednesday:  [tex]\dfrac{(x-75)}{48}[/tex]

If the number of bottles sold on Tuesday was 7 more than those sold on Wednesday:

[tex]\implies \dfrac{x}{45}-7=\dfrac{(x-75)}{48}[/tex]

multiply both sides by 48:  

[tex]\implies \dfrac{48x}{45}-336=x-75[/tex]

multiply both sides by 45:

[tex]\implies 48x-15120=45x-3375[/tex]

[tex]\implies 3x=11745[/tex]

[tex]\implies x=3915[/tex]

Therefore, 87 bottles were sold on Tuesday and 80 bottles were sold on Wednesday

Answer:

x = 9/2

Step-by-step explanation:

The outside triangle is also a right triangle, with hypotenuse 8 and side 6.

The missing side can be calculated with pythagoras as:

[tex]\sqrt{8^2-6^2} = \sqrt{28}[/tex]

Now for the vertical line, lets call it y, which is a side for two "back to back" triangles, you can do pythagoras twice:

left triangle: [tex]y^2 + (8-x)^2 = 28[/tex]

right triangle: [tex]y^2 + x^2 = 6^2[/tex]

Eliminating y², you can solve:

[tex]28 - (8-x)^2 = 36 - x^2[/tex]

Answer:

(a.) 27^4/3 = 81, (b.) 36^3/2 = 216, (c.) (1/8)^2/3 = 1/4, (d.) 128^5/7 = 32

Step-by-step explanation:

All these expressions can be converted in square roots.

In order to do this, we can picture the fractional exponents as exponent / index

(a.) So for this first problem, we would have the cube root of [tex]27^{\frac{4}{3} }[/tex] or

[tex]\sqrt[3]{(27)^{4} }[/tex].

We must do the equation inside the radical first (i.e., [tex](27)^{4}[/tex]) to get [tex]\sqrt[3]{531,441}[/tex] = 81

We can follow these same steps for the remaining equations:  

(b.) [tex]36^{\frac{3}{2} }[/tex] = [tex]\sqrt{(36)^3}[/tex] = [tex]\sqrt{46,656}[/tex] = 216

(c.) [tex](\frac{1}{8})^\frac{2}{3}[/tex] = [tex]\sqrt[3]{(\frac{1}{8})^{2} }[/tex] = [tex]\sqrt[3]{(\frac{1^2}{8^2}) }[/tex] = [tex]\sqrt[3]{(\frac{1}{64}) }[/tex] = [tex]\frac{1}{4}[/tex]

Answer:

equation;

[tex](x + 4) {}^{2} + (y - 2) {}^{2} = 27[/tex]

Center (-4,2)

Radius is

[tex]3 \sqrt{3} [/tex]

Step-by-step explanation:

Since the x^2 and y^2 have the same coeffiecent this will be a circle in a form of

[tex](x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]

Where (h,k) is center

r is the radius

So first we group like Terms together

[tex] {x}^{2} + 8x + {y}^{2} - 4y - 7 = 0[/tex]

Add 7 to both sides

[tex] {x}^{2} + 8x + {y}^{2} - 4y = 7[/tex]

[tex]( {x}^{2} + 8x) +( {y}^{2} - 4y) = 7[/tex]

Since the orginal form of the equation of the circle has a perfect square we need to complete the square for each problem

[tex] (\frac{8}{2} ) {}^{2} = 16[/tex]

and

[tex]( - \frac{4}{2} ) {}^{2} = 4[/tex]

so we have

[tex] {x}^{2} + 8x + 16 + {y}^{2} - 4y + 4y = 7 + 16 + 4[/tex]

[tex] {x}^{2} + 8x + 16 + {y}^{2} - 4y + 4y = 27[/tex]

[tex](x + 4) {}^{2} + (y - 2) {}^{2} = 27[/tex]

To find our center, h is -4 and k is 2

so the center is (-4,2)

The radius is

[tex] \sqrt{27} = 3 \sqrt{3} [/tex]

So the radius is 3 times sqr root of 3.

Approximate the sum of the first 17 terms to the nearest tenth.

Sum =

-204.8

Step-by-step explanation:

The value  [tex]a_1[/tex] is -256.

The value  r = -1/4

A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.

Example:

2, 4, 8, 16 is a geometric sequence.

We have,

In a geometric sequence,

Each term is obtained by multiplying the preceding term by a constant factor, which is called the common ratio (r).

So,

The nth term of the sequence.

[tex]a_n[/tex] = -256 x [tex](-1/4){n-1}[/tex]

Now,

[tex]a_1[/tex] = -256 x [tex](-1/4)^{1 -1}[/tex]

   = -256 [tex](-1/4)^0[/tex]

   = -256 x 1

   = -256

[tex]a_2[/tex] = -256 x [tex](-1/4)^{2-1}[/tex]

   = -256 x [tex](-1/4)^1[/tex]

  = -256 x -1/4

  = 64

Now,

[tex]a_1[/tex] r = [tex]a_2[/tex]

-256 x r = 64

r = 64 / -256

r = -1/4

Answer:

Step-by-step explanation:

Find the area of the rectangle. A = length * width

Find the area of each circle.   A = π*radius*radius

Subtract the area of each circle from the area of the rectangle.

A = length * width

A = (3+6+9+12) * 18

A = 30 * 18

A = 540 square inches

Bottom circle

A = π * radius * radius.  (radius is 1/2 of the diameter)

A = 3.14 * 6 * 6

A = 133.04 square inches

Middle circle

A = π * radius * radius

A = 3.14 * 4.5 * 4.5

A = 63.59 square inches

Top circle

A = π * radius * radius

A = 3.14 * 3 * 3

A = 28.26 square inches

Subtract the circles from the rectangle.

540 - 133.04 - 63.59 - 28.26 = 315.11 square inches is the area of the shaded part.

Answer:

x = [tex]\sqrt{48}[/tex]

Angle B = 60 degrees

Step-by-step explanation:

Since the triangle is equilateral, we know that all sides will be 8 units long. Side CB is split in half so each half (CD and DB) are 4 units long. Side CA is 8 units long and is the hypotenuse for triangle ACD. To find the unknown side (AD aka x):

4^2 + x^2 = 8^2.     use the pythagorean theorem

16 + x^2 = 64.     subtract 16 from both sides

x^2 = 48.     take the square root of both sides

x = [tex]\sqrt{48}[/tex]

For angle B, we know that all the angles in triangle ABC will be the same since it is an equilateral triangle.

180/3 = 60.     total sum of all angles in a triangle will be 180 so divide that by total angles (3)

Angle B = 60 degrees

The value of x is 6.92 units.

The measure of angle B is 60 degree.

The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.

Given:

Since the triangle is equilateral all sides will be 8 units long.

and, CD or DB  = 1/2 (CB)

                          = 4 units long.

Now, In ΔACD using Pythagoras theorem

4² + x² = 8²

16 + x² = 64

x² = 48

x = 6.92 unit.

and, We know all three angles of Equilateral triangle are Equal in measure.

So, 180/3 = 60.
