Joshua just bought a new fish tank. The tank is 14 inches tall and has a radius of 4 inches. How much water can Joshua put in the tank? Use 3.14 for pi. *
A. 703.36 cubic inches
B. 56 cubic inches
C. 224 cubic inches
D. 175.84 cubic inches

Answers

Answer 1

Answer:

V = 703.36 in³   (This matches answer option A.)

Step-by-step explanation:

This fish tank has a cylindrical shape.  The formula for the volume of a cylinder of radius r and height h is

V = (pi)(r²)(h).

We are told that h = 14 in and r = 4 in.  Using 3.14 for pi:

V = (3.14)(4 in)²(14 in) =

V = 703.36 in³   (This matches answer option A.)

The mean weight of females in a class is 60kg and that of the males is 72kg. If the mean

weight of the class is 68kg, what is the ratio of females to males in the class?​

Answers

Answer:

1:2

Step-by-step explanation:

Let's say there are x males and y females in the class.

The sum of all male weights will be 72x, and the sum of all female weights will be 60y.

If we get a class mean weight, we have:

(72x + 60y) / (x+y) = 68

72x + 60y = 68x + 68y

4x = 8y

y / x = 4/8 = 1/2

So the ratio of females to males is the class is 1:2

The radius of a circle is 2 centimeters. What is the circles circumference?

Answers

Answer: 4π cm or 12.56 cm

Step-by-step explanation: To find the circumference of this circle, start with the formula for the circumference of a circle which is C = 2πr.

Since the radius is 2 centimeters, we can

plug in 2 centimeters for r in the formula.

So we have (2)(π)(2 cm) which is equal to 4π cm.

So the circumference of this circle is 4π cm.

Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.

So we have (4)(3.14) which is equal to 12.56.

So the circumference of the circle is

approximately equal to 12.56 cm.

A city is divided by a river. The portion of the city east of the river covers 25% of the city and has a population density of 28 people/km2. The portion on the west side of the river has a population density of 17 people/km2. Find the population density of the city as a whole.

Answers

Answer:

The answer is 19,75 people / km2

Step-by-step explanation:

Let's say that the total area of the city is 4 kilometer squares. In that case, the east of the river, which is 25% of the city, is 1 kilometer square. This means that the population is 28 on the east side of the city

The west side of the city is 3 kilometer squares, which means the population is 17 x 3 = 51.

The total population of the city is 51 + 28 = 79 and the total area is 4 kilometer squares. So the population density of the city as a whole is

79 / 4 = 19,75 people per kilometer square.

Find the total volume of the rectangular prisms.
A) 88 units3
B) 96 units3
C) 104 units3
D) 114 units3

Answers

Answer:

C) 104 units^3

Step-by-step explanation:

The formula for volume in a rectangular prism is V=lwh

There are three total rectangular prisms, so take the volume of each individual prism and add them together to get the total volume.

smallest: V=(2)(2)(4) = 16

Medium: (2)(2)(6) = 24

Largest: (2)(2)(16) = 64

Add it together: 16+24+64= 104

Your answer is 104 units^3

For every bracelet she​ sells, she gives her business partner​ $4. If Latrece sells 18 bracelets for a total of​ $207, how much money will Latrece keep from each bracelet​ sold?

Answers

Answer:

Latrece gets to keep 135.

Step-by-step explanation:

so you would multiply 18 by 4 to get 72. Then you would subtract 207 by 72 to get 135

Answer:

7.50

Step-by-step explanation:

For 18 bracelets

She will give per partner

18*4 =72

She will keep  all but 72 dollars

207 - 72 =135

She wants to know how much per bracelet so divide by the number of bracelets

135 / 18 =7.5

The diagram shows a square-based cuboid.
10 cm
4 cm
Work out the volume of the cuboid.
State the units of your answer.

Answers

Answer:

400 cubic cm

Step-by-step explanation:

Given that base is square and is side is 10 cm

area of square is given by side^2

Thus, area of base of cuboid  = [tex]10^2[/tex] square cm = 100 sq. cm

We know volume for any cuboid is area of base * height

height is 4cm

thus, volume of cuboid = area of base of cuboid * height

                                     = 100 * 4 cubic cm = 400 cubic cm

Volume of cuboid is 400 cubic cm.

Unit is cubic cm

The volume of square based cuboid is [tex]400cm^{3}[/tex].

Given that, base is square and side of base is 10 cm.

Height of the square-based cuboid.is 4cm.

Area of base = [tex](side)^{2}=(10)^{2}=100cm^{2}[/tex]

Volume of the cuboid is multiplication of base area and height of the cuboid.

  [tex]Volume=100*4=400cm^{3}[/tex]

Hence, the volume of square based cuboid is [tex]400cm^{3}[/tex].

The data on ages at which a sample of 35 fathers had their first child show a mean 25.43 and standard deviation 5.19. Define the population parameter of interest in this context.

Answers

Answer:

Step-by-step explanation:

A population parameter describes an entire population; a particular characteristic of an entire population. A value that describes the entire population. In this context, the population parameter is looking into the average ages of fathers when they had their first child, but this value is not given. The mean given here is the sample statistic.

Since, the population studied here is a very large population (all fathers), you have a statistic. But sometimes, if the population is very small and groups are small enough to measure, you have a parameter.

Triangle A is a scaled version of triangle B. The dimensions of triangle B are three times the dimensions of triangle A. The area of triangle A is 24.5 sq cm. What is the area of triangle B?

Answers

Answer:

The  area of triangle B is [tex]2.72cm ^{2}[/tex]

Step-by-step explanation:

We will use the principle of similar triangles to solve the problem.

Since triangle A is just a scale version of triangle B, we can say that the two triangles are similar.

The area scale factor is the square of the length scale factor.

Given the length scale factor as 3,

The area scale factor will be 3 X 3 = 9 sq. cm

(Area of triangle A / Area of triangle B) =  (length of side A / Length of side B) square

[tex]\frac{24.5}{ area of B}= 3^{2}[/tex]

[tex]\frac{24.5}{Area of B}= 9\\Area of B = \frac{24.5}{9}= 2.72 cm ^{2}[/tex]

The  area of triangle B is [tex]2.72cm ^{2}[/tex]

Sales Gi sells televisions. He earns a fixed amount for each television and an additional $ 30 if the buyer gets an extended warranty. If Gi sells 14 televisions with extended​ warranties, he earns $ 1 comma 190. How much is the fixed amount Gi earns for each​ television? The fixed amount Gi earns for each television he sells is ​$ nothing.

Answers

Answer:

The fixed amount Gi earns for each television he sells is $ 55.

Step-by-step explanation:

If Gi sold 14 televisions and earnt a total of $1,190, then for each television that was sold he earnt:

per tv = total earnt/total sold

per tv = 1190/14 = 85

Since he sold all these televisions with warranty, then he earned "x + 30" per each tv sold, since he got the bonus from the warranty. Therefore the fixed amount he earns per tv is:

x + 30 = 85

x = 85 - 30

x = 55

The fixed amount Gi earns for each television he sells is $ 55.

Use 3.14 for π, and round your answer to the nearest tenth.

a cone with a height of x and a radius of w, a cylinder with a diameter of y and a height of z
please help me

Answers

The cone holds 44 cubic inches more ice cream than a cup.

Important information:

Height of a cone is x =6 in and radius w = 4 in.Diameter of a cylinder is y = 6 in and height z = 2 in.

We need to find the volumes of each ice cream container.

Volume:

Volume of the cone is:

[tex]V_1=\dfrac{1}{3}\pi r^2h[/tex]

[tex]V_1=\dfrac{1}{3}(3.14) (4)^2(6)[/tex]

[tex]V_1=100.48[/tex]

The diameter of the cylinder is 6 in so the radius is 3 in.

Volume of the cylinder is:

[tex]V_2=\pi r^2h[/tex]

[tex]V_2=(3.14)(3)^2(2)[/tex]

[tex]V_2=56.52[/tex]

Clearly [tex]V_1>V_2[/tex].

[tex]V_1-V_2=100.48-56.52[/tex]

[tex]V_1-V_2=43.96[/tex]

[tex]V_1-V_2\approx 44.0[/tex]

Therefore, the cone holds 44 cubic inches more ice cream than a cup.

8^2 + 16^2 = 20^2
