Answer:

=30 ft³

Step-by-step explanation:

From the scenario given the formula for density of the fish pod is

ρ= no. of fish/ volume

Making volume the subject of the formula we obtain the following equation:

Therefore volume = no.of fish/ρ

Using the values provided in the question:

=12 fish/0.4 fish/ft³

=30 ft³

= 4.8

Answer:

Step-by-step explanation:

Volume = 30 ft³

density = population/area

.4  =  12/ft³

(.4)(ft³) = 12/ft³ × ft³/1

.4 ft³ = 12

.4ft³ /.4 = 12/.4

ft³ = 30

30 ft³

The answer you are looking for could either be 16 or 40.  To solve the equation, you would follow the steps of PEMDAS. Since the 2 above the equation is an exponent, you'd first solve there.  

Fill in "a" and "b", the equation will now say 2^2 * 3 + 4 = ?. Assuming that the exponent is meant to go with the 2 alone, 2 * 2 = 4. This leaves the equation to say 4 * 3 + 4 = ? Multiply 3 and 4 to get 12, then add 4 to get 16.  

OR  

Fill in "a" and "b". This time, we're assuming that the exponent is going with 2 * 3 (originally 2a). Multiply 2 and 3 to get 6, then square 6 to get 36. Finally, add 4 to 36 to get 40.  

I'm not quite sure where the exponent was meant to go, but I hope this helps!

Answer:

The exact values of sin2Ф and cos2Ф are as follows:

sin2Ф = 0.8983

cos2Ф = 0.4394

Step-by-step explanation:

sin Ф = 9/17 = perp/hyp = y/r

we know that:

r² = x²+y²

17² = x² + 9²

x² = 208

x = 4√13

cos Ф = base/hyp = x/r = (4√13)/17

Solving sin2Ф

we know that:

sin2Ф = 2 sinФ cosФ

= 2*(9/17)*((4√13)/17)

= (72√13)/289

= 0.8983

Solving cos2Ф:

we know that:

cos2Ф = 1 - 2sin²Ф

= 1 - 2(9/17)²

= 1 - 0.5606

= 0.4394

Answer:

26

Step-by-step explanation:

x is a degree so it can't be no more then 60 so the angle should be 26

The value of x is 60 degrees, as determined through a series of geometric deductions based on the properties of triangles and semicircles. Here option B is correct.

The sum of the angles in a triangle is 180 degrees.

The sum of the angles in a semicircle is 180 degrees.

The angle opposite to the diameter of the circle is 90 degrees.

Therefore, the angle x in the first triangle is 180 - 90 - 52 = 38 degrees.

The angle x in the second triangle is 180 - 38 - x = 142 - x degrees.

The angle x in the second triangle is also equal to the angle x in the semicircle, which is 180 - 52 - x = 128 - x degrees.

Equating the two expressions for the angle x in the second triangle, we get 142 - x = 128 - x.

Solving for x, we get x = 60 degrees. Here option B is correct.

Answer:

d = 10.8167

Step-by-step explanation:

The distance between two points can be easily found by using the following expression

d = √((x1-x2)^2 + (y1-y2)^2)

where

(x1,y1) = (6,-4)

(x2,y2) = (0,5)

d = √((6-0)^2 + (-4-5)^2)

d = √(36 + 81)

d = √(117)

d = 10.8167

Answer:

The distance between the points (6,-4) and (0,5) = 10.82 units

Step-by-step explanation:

Points to remember

Distance formula

Length of a line segment with end points (x1, y1) and (x2, y2) is given by,

Distance = √[(x2 - x1)² + (y2 - y1)²]

To find the distance between given points

Here, (x1, y1)  =  (6, -4) and (x2, y2)  = (0, 5)

Distance = √[(x2 - x1)² + (y2 - y1)²]

 = √[(0 - 6)² + (5 - -4)²]

 =√[(-6)² + (9)²]

 = √[36 + 81]

 = √[117

 = 10.82

The distance between the points (6,-4) and (0,5) = 10.82 units

Answer:

4 1/4 gallons

Step-by-step explanation:

5 gallons are needed.

Convert one gallon into quarts and one quart into pints.

3 quarts and 2 pints, minus 3 quarts and 1 pint.

The result is 4 gallons and 1 pint.

He needs 4 galloons and 1 pint .

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

A painter needs 5 gallons of paint to finish a house.

He has 3 quarts and 1 pint.

Now, Convert one gallon into quarts and one quart into pints.

3 quarts and 2 pints

= 0.75 + 0.125

= 0.875 gallons

So, amount of paint needs = 5- 0.875

To find the inverse of the given function, we need to switch the roles of x and y and solve for y.

To find the inverse of a function, we need to switch the roles of x and y, and then solve for y. So, let's start:

Given f(x) = 4x

Switching the roles, we have x = 4y

Now, solve for y:

x = 4y

Divide both sides by 4:

y = x/4

The inverse function is h(x) = x/4. Therefore, the correct option is h(x) = x/4.

Answer:

no real solution is the answer

If you have to list your extraneous solutions somewhere, that would be x=0.

Step-by-step explanation:

Cool thing here is the radical, the thing with the square root, is already isolate.

So we need to square both sides as a first step.  (Whenever you raise both sides to even power, you must definitely check your solutions as some might not actually be solutions to the original equation)

So upon squaring both sides I get:

x^4+16=(x^2-4)^2

Now I will write (x^2-4)^2 as (x^2-4)(x^2-4) and foil it!  This gives me:

x^4+16=x^4-8x^2+16

Subtract x^4 and 16 on both sides:

       0=-8x^2

Divide both sides by -8

      0=x^2

Therefore x=0.

0 isn't actually a solution though because when you plug it in you get 4=-4 which is not true.

A full circle is 360 degrees.

Step-by-step explanation:

Given  : A circle with circumferences = 104 cm , central angle = 45°.

To find :  what is the length of arc AB.

Solution : We have given  circle with circumference = 104 cm , central angle = 45°.

Arc length = [tex]\frac{theta }{360} * circumference[/tex].

 Plug the values circumference = 104 cm , central angle = 45°.

Arc length = [tex]\frac{45 }{360} * 104[/tex].

Arc length = 0.125 * 104

 Arc length  = 13 cm .

Step-by-step explanation:

Step-by-step explanation:

Here,

radius of hemisphere and cylinder(r)=7 cm

height of the cylinder(h)= 10 cm

Now the volume of cylinder(V1) is,

[tex]\pi {r}^{2} h \\ = \pi \times {7}^{2} \times 10 \\ = 1540 \: {cm}^{3} \\ [/tex]

And the volume of hemisphere(V2) is,

[tex] \frac{2}{3} \pi {r}^{3} = \frac{2}{3} \times \pi \times {7}^{3} \\ = 718.67 \: {cm}^{3} [/tex]

Total volume=V1+V2=1540+718.67= 2258.67 cu.cm

Surface area of cylinder(A2)=

[tex]2\pi \: rh + 2\pi {r}^{2} = 2\pi \: r(h + r) \\ = 2 \times \pi \times 7 \times (10 + 7) \\ = 44 \times 17 \\ = 748 \: {cm}^{2} [/tex]

Surface area of hemisphere(A2)=

[tex]2\pi {r}^{2} = 2 \times \pi \times {7}^{2} = 308 \: {cm}^{2} [/tex]

Then total Surface area=A1+A2

=748+308=1056 sq.cm

1. First, let us find the volume. Now the total volume is simply given by adding the volume of the cylinder to that of the hemisphere.

Let us revisit the formulas for the volume of a cylinder and hemisphere.

Cylinder: V = πr^(2)h

Hemisphere: V = (2/3)πr^3

Thus, the total volume is given by πr^(2)h + (2/3)πr^3

Using the values provided in the diagram, we can now say that:

Total volume = π(7)^(2)*10 + (2/3)π(7)^3

= 490π + 686π/3

= 2156π/3 cm cubed

Using π = 22/7, we can now see that:

Total volume = 2156*(22/7) / 3

= 2258.67 cm cubed (to two decimal places)

2. Now let's find the total surface area. Let's review the formulas for total surface area for a cylinder and a hemisphere:

Cylinder: SA = 2πr^2 + 2πrh (this is the area of the top and bottom, plus the area of the rectangle that is wrapped around)

However, since the top of the cylinder is covered by the hemisphere, we don't need to count its area in the surface area, thus we must use SA = πr^2 + 2πrh

Hemisphere: SA = πr^2 + 2πr^2 = 3πr^2 (this is the area of the bottom of the hemisphere plus the area of half of the sphere)

However, since the bottom of the hemisphere is on the cylinder, we don't count this in the total surface area either, therefor we must use SA = 2πr^2

Thus, total surface area is given by:

πr^2 + 2πrh + 2πr^2

= 3πr^2 + 2πrh

Now we can substitute the values of the radius and cylinder height into the formula above. So:

TSA = 3πr^2 + 2πrh

TSA = 3π(7)^2 + 2π(7)(10)

= 147π + 140π

= 287π cm squared

Using π = 22/7, we can now see that:

TSA = 287*(22/7)

= 902 cm squared

36 donuts (2 1/2 dozen) = $8.00

So, you divide 8 by 36 and you get about 22¢ for each donut. Then, you do .22 x 12 which equals $2.64.

One dozen donuts = $2.64

The cost of the one dozen donuts will be $2.64.In one dozen their is 12 donuts.

Arithmetic is an area of mathematics involving the study of numbers and the different operations that can be performed on them.

[tex]\rm 1 \ dozen = 12 \ donuts \\\\ 2\frac{1}{2} dozen = 2\frac{1}{2} \times 12\\ \\\\ 2\frac{1}{2} dozen = 36 \ donuts[/tex]

36 donuts=  $8.00

1 donuts =  $ 0.22

1 dozen donuts cost  = 12 × $ 0.22

1 dozen donuts cost  = $ 2.64
