Answer:

4th option

Step-by-step explanation:

Answer:

I think That answer is A.

Step-by-step explanation:

If you double all of the dimensions of a rectangular prism, you create a similar prism with a scale factor of 2. The surface area of the similar prism will increase as the square of the scale factor (22 = 4) and the volume will increase as the cube of the scale factor (23 = 8).

Answer:

Guido tiene 9 años, Andrés tiene 36 años y David tiene 3 años.

Step-by-step explanation:

Con la información proporcionada, sabes que la edad de los tres suma 48, lo que se puede expresar como:

x+y+z=48, donde:

x es la edad de Guido

y es la edad de Andrés

z es la edad de David

Además, de acuerdo al enunciado puedes decir que la edad del papá Andrés es cuatro veces la edad de Guido y que la edad de David es la tercera parte de la edad de Guido y puedes escribir las siguientes ecuaciones:

y=4x

z=x/3

Ahora puedes reemplazar estas dos ecuaciones en la primera y despejar x:

x+4x+x/3=48

5x+x/3=48

16x/3=48

16x=48*3

16x=144

x=144/16

x=9

Después, puedes reemplazar el valor de x en y=4x para encontrar el valor de y:

y=4x

y=4*(9)

y=36

Finalmente, debes reemplazar el valor de x en z=x/3 para encontrar el valor de z:

z=x/3

z=9/3

z=3

De acuerdo a esto, Guido tiene 9 años, Andrés tiene 36 años y David tiene 3 años.

Answer:

2.4

Step-by-step explanation:

We divide 0.5 by 3 giving us approximatly 0.16, we have found the rate of change. Now we multiply 15 by 0.16 equals 2.4.

Step-by-step explanation:

substitute for y

x+3+4 = -6x

x+ 7 = -6x

7 = -7x

-1 = x

y = -1+3

y = 2

Given:

Post office is located at P(1,5).

Market is located at Q(4,9).

To find:

Distance between the post office and the market.

Solution:

Distance between two points is:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The post office is located at P(1,5) and the market is located at Q(4,9). So, the distance between the post office and the market is:

[tex]PQ=\sqrt{(4-1)^2+(9-5)^2}[/tex]

[tex]PQ=\sqrt{(3)^2+(4)^2}[/tex]

[tex]PQ=\sqrt{9+16}[/tex]

[tex]PQ=\sqrt{25}[/tex]

[tex]PQ=5[/tex]

The axes show distance in miles.

Therefore, the distance between the post office and the market is 5 miles.

The volume of the pyramid with a square base is 135.5 cubic m if the base area is 16 cubic m and the height is 25.4 m.

In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the square's joints at the top, which is perpendicular to the centre of the square.

We know the volume of the square pyramid V;

V = Bh/2

B is the base area, B = 16 square m

h is the height of the pyramid, h = 25.4 m

V = (16×25.4)/3

V = 135.46 ≈ 135.5 cubic m

Thus, the volume of the pyramid with a square base is 135.5 cubic m if the base area is 16 cubic m and the height is 25.4 m.

Answer:

[tex]525\pi[/tex]

Step-by-step explanation:

Volume of a cylinder is given by the function [tex]v=\pi r^{2}h[/tex]

where v is volume, r is radius and h is height.

In order to find the radius we just divide the diameter in half and get

[tex]\frac{10}{2} =5=r[/tex]

now we just plug the values in the formula

[tex]v=\pi r^{2}h\\=\pi (5^{2})(21)\\=\pi (25)(21)\\=525\pi[/tex]

Answer:

Volume of a cylinder: V = π (r^2) h

Step-by-step explanation:

First, find your radius and your height.

H = 21

D = 10

R = 1/2 d = 5

Then plug them into the equation: V = π (r^2) h

V = π (5^2) 21

V = π (25) 21

V = π (25 x 21)

V = π (525)

V = 525π

Answer:

339n in^3

Step-by-step explanation:

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

Water in the cylinder = volume of cylinder - volume of sphere

volume of a cylinder = nr^2h

n = 22/7

r = radius = 10/2 = 5

n x (5^2) x 15 = 375 in^3

volume of a sphere = (4/3) x (n) x (r^3)

n = 22/7

r = 6/2 = 3

(4/3) x (n) x (r^3) =  36n

Step-by-step explanation:

Well according to the picture (it doesn't have the full problem so this is what I can explain):

To make 1 dozen cupcakes (x), you need 1 cup of butter (y). (Or you can see in the question on the picture: y = 0.5x)

So let's say, he wants to make half a dozen cupcakes, he would need 0.5 cups of butter. How many cups of butter he uses is how many dozens he can make.

Answer: C

Step-by-step explanation:

Given:

The expression is:

[tex]2b^3+5[/tex]

To find:

The value of the given expression when [tex]b=3[/tex].

Solution:

We have,

[tex]2b^3+5[/tex]

Substituting [tex]b=3[/tex] in the above expression, we get

[tex]2b^3+5=2(3)^3+5[/tex]

[tex]2b^3+5=2(27)+5[/tex]

[tex]2b^3+5=54+5[/tex]

[tex]2b^3+5=59[/tex]

Therefore, the value of given expression at [tex]b=3[/tex] is 59.

Answer:

The answer is 59

Step-by-step explanation:

2b³ + 5, b = 3

2(3)³ + 5

2 × 27 + 5 = 59

Thus, The answer is 59

Answer:

62.8 inches

Step-by-step explanation:

✓We can determine the

Circumference of the wheel of the bicycle using the expression below;

Circumference= (πd) ...........eqn(1)

Where d= diameter = 20inches

If we substitute the value of " diameter" into eqn(1)

Circumference = (π × 20)

= 62.8inches

(Where π= 3.142)

Therefore, measurement that is closest to the circumference of the wheel is 62.8inches
