Answer:

the unit price for the 2.38 pound bag $5.03 lb.

the unit price for the 4.01 pound bag $4.86 lb

The better buy: $4.86

The unit prices are $5.033 per pound and $4.85 per pound, and 4.01-pound bag is better buy choice.

The unit price refers to the price per unit of measures, such as price per pound, quart, ounce, or other units of weight or volume of the food package.

Given that, Dan paid $11.98 for a 2.38-pound bag of shrimp at one store, on other shop he spend $19.49 for a 4.01-pound bag,

We need to find the unit price of each and which one is the better buy,

The better buy will be the one having less unit rate,

Unit price for the 2.38-pound bag = 11.98 / 2.38 = $5.033 per pound

Unit price for the 4.01-pound bag = 19.48 / 4.01 = $4.85 per pound

Since, the unit price of the 4.01-pound bag is less therefore, this is the better buy choice.

Hence, the unit prices are $5.033 per pound and $4.85 per pound, and 4.01-pound bag is better buy choice.

Answer:

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

Step-by-step explanation:

Given

[tex]\frac{180}{80}=\frac{80}{80}*a^6[/tex]

Required

Solve for a

[tex]\frac{180}{80}=\frac{80}{80}*a^6[/tex]

[tex]\frac{180}{80}=1*a^6[/tex]

[tex]\frac{180}{80}=a^6[/tex]

[tex]a^6 = \frac{180}{80}[/tex]

[tex]a^6 = \frac{18}{8}[/tex]

[tex]a^6 = \frac{9}{4}[/tex]

Take the square root of both sides

[tex]\sqrt{a^6} = \sqrt{\frac{9}{4}[/tex]

[tex]a^3 = \frac{3}{2}[/tex]

Take cube rooth of both sides

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

Answer:

4x+6

Step-by-step explanation:

The quotient of a number and 4 translates to 4x because, "a number" in the expression is x, and it is being multiplied by 4, so you get 4x. six more than would mean adding 6. So the answer would be 4x+6. Thank you! Good Luck!

a) False. This can be proven by the fact that a rotation around a point (not necessarily on the circles) can map 2 circles onto each other.

b) False. Rotations, reflections, and dilations (the last one applies if the circles have different radii) can map one circle onto another.

c) True. All circles are a uniform distance (the radius) from a point (the center), so there is only one length that defines a circle, the radius. Since a:b = a:b, where a = the radius of one circle while b = radius of another circle, that means that 2 circles will always be similar (because all corresponding lengths are in the same ratio)

I’m so sorry I wish I could help

Step-by-step explanation:

Answer: So each hour represents 30°.

The minute hand moves 60s per minute and a full rotation is 360° so: 360/60 = 6° per minute.

So in 20 minutes the minute hand will be 6 * 20 = 120° and the hour hand will be 120/12 = 10°.

so it would be 10°

Step-by-step explanation:

The height of the given Ferris wheel can be described with the aid of a

sinusoidal function.

The height above the ground in terms of the angle turned, a, is

presented as follows;

The height above the ground in terms of the distance traveled, s, is

presented as follows;

Reason:

The general form of an equation of a Ferris wheel is presented as follows;

f(a) = A·sin(a + C) + D

Where, the amplitude, A = The radius = 37 ft.

D = The midline = Height above the ground + The amplitude

D = A + 0.6 = 37 + 0.6 = 37.6

The 6 O'clock is the lower most position, therefore, at the start, where, 'B·t + C' = 0, we have;

f(a) = A·sin(0 + C) + D

Therefore

f(a) = 37·sin(0 + C) + 37.6 = 0.6

f(a) = 37·sin(C) = 0.6 - 37.6 = -37

[tex]sin(C) = \dfrac{-37}{37} = -1[/tex]

C = sin⁻¹(-1) = [tex]-\dfrac{\pi}{2}[/tex]

The equation of Ferris wheel is presented as follows;

Which gives the equation of the height above the ground (in feet) in terms

of the number of radians, a, you have swept out from the 6 O'clock

position is given as follows; Ferris ;

Part 2

s = a·r = a·A

Therefore;

[tex]a = \dfrac{r}{s} = \dfrac{A}{s} = \dfrac{37}{s}[/tex]

Plugging the value of s into the above equation gives the function that

determines the height above the ground (in feet) in terms of the number of

feet traveled g(s) as follows;

By the Pythagorean Theorem a^2+b^2=c^2 or the sum of the squared sides is equal to the hypotenuse squared.

41^2=9^2+h^2

h^2=41^2-9^2

h^2=1600

h=40 ft

Answer:

Density is defined as:

Density = mass/volume.

We know that:

For liquid A:

Density = 70kg/m^3

Mass = 1400kg

Then the volume is:

Volume = mass/density = (1400kg)/(70kg/m^3) = 20 m^3

For liquid B:

Density = 280 kg/m^3

Volume = 30m^3

We can find the mass of liquid B as:

mass = density*volume = (280kg/m^3)*(30m^3) = 8400 kg

We know that liquid C is a mixture of liquid A and B.

Then the mass of liquid C will be equal to the sum of the masses of liquid A and B, then:

Mass of liquid C = 1400kg + 8400kg = 9800kg

The same happens for the volume, then:

Volume of liquid C = 30m^3 + 20m^3 = 50m^3

Then the density of liquid C is:

Density of liquid C = (9800kg)/(50m^3) = 196 kg/m^3

Answer:

Mean

Step-by-step explanation:

Answer:

x = 36/5

Step-by-step explanation:

Subtract 6 from both sides

x/3+6-2x-6 = -6-6

Simplify

x/3 - 2x = -12

Multiply both sides by 3

x/3 * 3 - 2x * 3 = -12 * 3

Simplify

-5x = -36

Divide both sides by -5

-5x/-5 = -36/-5

Simplify

x = 36/5
