Step-by-step explanation:

To solve for a side using pythag:

[tex]\sqrt{37^2-35^2}[/tex]

The value of [tex]\( x \)[/tex] in a prism with volume [tex]\( 90 \)[/tex] cubic meters is approximately [tex]\( 2.466 \)[/tex] meters.

To find the value of [tex]\( x \)[/tex], knowing the volume [tex]\( V \)[/tex] of the prism, use the formula:

[tex]\[ V = l \times w \times h \][/tex]

Given [tex]\( V = 90 \)[/tex] cubic meters, if we assume the length [tex]\( l = 3x \)[/tex], width [tex]\( w = 2x \)[/tex], and height [tex]\( h = x \)[/tex], then:

[tex]\[ 90 = (3x) \times (2x) \times (x) \][/tex]

[tex]\[ 90 = 6x^3 \][/tex]

[tex]\[ x^3 = \frac{90}{6} \][/tex]

[tex]\[ x^3 = 15 \][/tex]

[tex]\[ x = \sqrt[3]{15} \][/tex]

[tex]\[ x \approx 2.466 \] meters.[/tex]

The interest earned is $14.

To find the interest earned, we can use the formula for simple interest:

[tex]\[ \text{Simple Interest} = \frac{P \times R \times T}{100} \][/tex]

Where:

- [tex]\( P \)[/tex]is the principal amount (the initial amount of money) [tex]= $800[/tex]

-[tex]\( R \)[/tex]is the interest rate per period (in decimal form) [tex]= 3.5% = 0.035[/tex]

-[tex]\( T \)[/tex] is the time the money is invested for (in years)[tex]= 6 months = 0.5 years[/tex]

Now, plug in the values:

[tex]\[ \text{Simple Interest} = \frac{800 \times 3.5 \times 0.5}{100} \][/tex]

[tex]\[ \text{Simple Interest} = \frac{800 \times 3.5 \times 0.5}{100} \][/tex]

[tex]\[ \text{Simple Interest} = \frac{800 \times 1.75}{100} \][/tex]

[tex]\[ \text{Simple Interest} = \frac{1400}{100} \][/tex]

[tex]\[ \text{Simple Interest} = \[14 \][/tex]

Complete correct question:

Principal = $800

Interest Rate = 3.5%

Time = 6 months

Answer:

11 ft

Step-by-step explanation:

The ring takes circular shape and for a circle, circumference is given by

[tex]C=\pi d[/tex]

Where C represent circumference and d is the diameter.

Taking use 3.14 for pi as instructed and substituting 3.5 ft for diameter d then

C=3.14*3.5=10.99 ft

Rounding off, this is approximately 11 ft

Answer:

10.99 ft

Step-by-step explanation:

Given: The ring has a diameter of 3.5 feet

To find: The ring's circumference

Formula: [tex]C = 2\pi r[/tex]

Solution: To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2 × radius with pi (π = 3.14).

C = pi × 2r

C = pi × diameter (3.5)

C = 3.14 × 3.5 = 10.99

Hence, the ring's circumference is 10.99 ft

Step-by-step explanation:

Answer:

13-4n

Step-by-step explanation:

The generic formula to calculate this is. a+(n-1) d

“a” is the first term and “d” is the difference in our case “a” is 9 and “d” is -4

9+(n-1)(-4)

9-4n+4

13-4n

Answer:

[tex]a_{n}[/tex] = 13 - 4n

Step-by-step explanation:

Note the common difference d between consecutive terms, that is

d = 5 - 9 = 1 - 5 = - 3 - 1 = - 7 - (- 3) = - 4

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 9 and d = - 4, thus

[tex]a_{n}[/tex] = 9 - 4(n - 1) = 9 - 4n + 4 = 13 - 4n ← explicit equation

To determine the ordered pair that is a solution, we need an equation or a system of equations.

The question asks to highlight the ordered pair that is a solution. To do this, you would need an equation or a system of equations to solve. Without the equation(s), it is not possible to determine the ordered pair that is a solution. Please provide the equation(s) so we can help you further.

Answer:

56-3=N

Step-by-step explanation:

David starts with 56 baseball cards and sells 3 per week, so the equation representing the cards remaining after W weeks is n = 56 - 3W.

The equation that represents the number of baseball cards David has left at the end of any given week W is n = 56 - 3W. Here, 'n' stands for the number of cards he has left, '56' is the initial number of cards, '3' is the number of cards he sells each week, and 'W' is the number of weeks that have passed.

For example, at the end of week 1 (when W = 1), David will have:
n = 56 - 3(1) = 56 - 3 = 53 cards left.

At the end of week 2 (when W = 2), it would be:
n = 56 - 3(2) = 56 - 6 = 50 cards remaining.
This pattern continues as more weeks pass.

Answer:

Step-by-step explanation:

They are the only 2 equivalent expressions

Answer:

C & E is the correct answer.

Answer:

The width of 48 feet is represented by 12.8cm; the length represented by 1cm is 48/12.8 = 15/4 = 3.75 feet.

The length on the drawing is 3.2cm, which is exactly 1/4 of the width of 12.8cm; therefore the length of the actual parking lot is 48/4 = 12 feet.

To find the actual length of a parking lot based on a scale drawing, you need the scale, which is often given as a ratio like '1 cm : 10 ft'. You would multiply the length on the drawing by the scale value to get the actual length. However, without the scale, a definitive answer cannot be provided.

To find the actual length of the parking lot, you need to know the scale of the drawing, which is not provided in the current question. The scale is usually expressed as a ratio, essentially representing a conversion factor. An example could be '1 cm : 10 ft', meaning every one centimeter on the drawing represents ten feet in real life.

Let's say the scale is '1 cm : 10 ft' as an example. You would then multiply the scale value (10 ft) by the length of the parking lot on the drawing (3.2 cm). So: 3.2 cm * 10 ft/cm = 32 ft. Hence, in this example, the actual length of the parking lot would be 32 feet. However, without the scale, we cannot provide a definitive answer.

The values are vx = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex], vw = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex] and m∠x = 45°, for the given right angle diagram.

Step-by-step explanation:

The given is,

                Right angled triangle XVW,

                                     XW = 14[tex]\sqrt{3}[/tex]

                                   m∠V = 90°

                                  m∠W = 45°

Step:1

              Given diagram is right angle triangle,

              Trigonometric ratios for right angle is,

                                 [tex]sin[/tex] ∅ [tex]=\frac{Opp}{Hyp}[/tex]............................(1)

                                  [tex]cos[/tex] ∅ [tex]= \frac{Adj}{Hyp}[/tex] .........................(2)

                                  [tex]tan[/tex] ∅ [tex]= \frac{Opp}{Hyp}[/tex]..........................(3)

Step:2

             For the value of VX,

                                   [tex]sin[/tex] ∅ [tex]=\frac{VX}{XW}[/tex]

            From given,

                               ∅ = 45°

                           XW = 14[tex]\sqrt{3}[/tex]

           Above equation becomes,

                                     [tex]sin[/tex] 45 [tex]=\frac{VX}{14\sqrt{3} }[/tex]

            Where, Sin 45 = [tex]\frac{1}{\sqrt{2} }[/tex],

                                            [tex]\frac{1}{\sqrt{2} } = \frac{VX}{14\sqrt{3} }[/tex]

                                           [tex]VX = \frac{14\sqrt{3} }{\sqrt{2} }[/tex]

Step:3

              For the value of VW,

                                   [tex]cos[/tex] ∅ [tex]=\frac{VW}{XW}[/tex]

            From given,

                               ∅ = 45°

                           XW = 14[tex]\sqrt{3}[/tex]

           Above equation becomes,

                                     [tex]cos[/tex] 45 [tex]=\frac{VW}{14\sqrt{3} }[/tex]

            Where, cos 45 = [tex]\frac{1}{\sqrt{2} }[/tex],

                                            [tex]\frac{1}{\sqrt{2} } = \frac{VW}{14\sqrt{3} }[/tex]

                                           [tex]VW = \frac{14\sqrt{3} }{\sqrt{2} }[/tex]

Step:4

             For the value m∠x = a,

                                      [tex]tan[/tex] a [tex]=\frac{VX}{VW}[/tex]

            From given,

                            VX = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex]

                           VW = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex]

           Above equation becomes,

                                     [tex]tan[/tex] a [tex]=\frac{\frac{14\sqrt{3} }{\sqrt{2} } } {\frac{14\sqrt{3} }{\sqrt{2} } }[/tex]

                                      [tex]tan[/tex] a = 1

                                             a = [tex]tan^{-1}[/tex] (1)

                                             a = 45°

                                 m∠x = a = 45°

Step:5

            Check for solution,

                         m∠v  = m∠w + m∠x

                                   = 45° + 45°

                            90° =   90°

Result:

            The values are vx = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex], vw = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex] and m∠x = 45°, for the given right angle diagram.

The cost of each item that Danny bought in this case are: Pass of the fair was of $21, the cost of souvenir was $14 and the cost of burger was $3.5

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Given that:

The cost of burger is expressed in terms of cost of souvenir and of souvenir in terms of the cost for pass.

So, let we take:
Cost of pass = x dollars,

Then, cost of souvenir = 2/3 of x = 2x/3 dollars

And the cost of burger = 1/4 of cost of souvenir = 1/4 (2x/3) = [tex]\dfrac{2x}{12} = \dfrac{x}{6}[/tex] dollars.

Also, we have:

Total initial amount = Amount spent + Amount remaining

or

43 = Cost of all those 3 items + 4.5

[tex]43 = x + \dfrac{2x}{3} + \dfrac{x}{6} + 4.5\\43 = \dfrac{6x}{6} + \dfrac{4x}{6} + \dfrac{x}{6} + 4.5\\\\43 = \dfrac{11x}{6} + 4.5\\\\\text{Subtracting 4.5 from both the sides}\\\\43-4.5 = \dfrac{1x}{6}\\\\\\dfrac{11x}{6} = 38.5\\\\\text{Multiplying 6/11 on both the sides}\\\\x = \dfrac{6 \times 38.5}{11} = 21[/tex]

Thus, the cost of pass was $21

Now, we get:

Cost of souvenir = 2x/3 = [tex]\dfrac{2(21)}{3} = 2\times7 = 14[/tex] dollars,

and cost of burger = [tex]\dfrac{x}{6} = \dfrac{21}{6} = 3.5[/tex] dollars.

Thus, the cost of each item that Danny bought in this case are: Pass of the fair was of $21, the cost of souvenir was $14 and the cost of burger was $3.5

Answer:

[tex]Length\,\, of\,\, the\,\, track=420.44\,m\\\\Area\,\,covered \,\,by\,\, the\,\, track=5893.06\,m^2[/tex]

Step-by-step explanation:

Length of the Track:

Perimeter of the rectangle + Circumference of the two semicircle

Perimeter of the rectangle= [tex]2(Length+Width)[/tex]

[tex]Length=92\,m\\Width=46\,m[/tex]

Perimeter of the rectangle:

              [tex]=2(92+46)\\\\=2(138)\\\\=276\,m[/tex]

Circumference of Two Semicircle with same radius:

[tex]r=\dfrac{46}{2} =23\,m[/tex]

[tex]Circumference=2\times \pi \times r\\\\[/tex]

   [tex]=2\times 3.14\times 23\\\\=6.28 \times 23\\\\=144.44\,m[/tex]

Total Length of the track is :

[tex]=276+144.44\\\\=420.44\,m[/tex]

Area Covered by the track is :

Area of the two semicircle + Area of the rectangle

         [tex]=(\pi \times r^2) + (Length\times Width)\\\\=(3.14\times (23\times 23 ))+(92\times 46)\\\\=1661.06 +4232\\\\=5893.06\,m^2[/tex]

The total length of the oval track is 420.51m and the area enclosed by the track is 5893.90m².

The dimensions of the rectangular part of the track are 46m and 92m respectively. Thus, the total distance around the rectangle (perimeter) is 2*(46m + 92m) = 276m. The two semicircles on either end of the rectangle form a complete circle with a diameter of 46m. The circumference of this circle (which equates to the remaining path length of the race track) is given by the formula πd or π*46m ≈ 144.51m. Thus, the total length of the track is 276m + 144.51m = 420.51m.

As for the area enclosed by the track, it consists of two main parts: the area of the rectangle and the area of the circle. The area of the rectangle is given by the formula L*W, or 46m*92m = 4232m². The area of the circle is given by the formula π(r²), where r is the radius of the circle. So, π(23m²) equals approximately 1661.90m². Adding the two results together, the total area enclosed by the track is 4232m² + 1661.90m² = 5893.90m².
