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

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: d)

Step-by-step explanation:

While a) is possible, theories are usually backed up by some evidence making it, in that case not just an educated guess. An hypothesis on the other hand is an educated guess.

b) is not specific to what it is talking to but if it's about laws, then yes it's right but theories are not always widely accepted. In fact it isn't likely that they would be accepted at all since it's not a fact or law.

c) is just wrong because theories can become law if enough evidence is found. Which is a change that can happen over time so that is just incorrect

d) is correct because enough evidence can make an hypothesis into a theory because it's backed by some evidence(although it make have some holes in it) and if there is enough concrete evidence, a theory can become a law

Answer: THIS IS SO HARD!

Step-by-step explanation:

The required boiling temperature of platinum is 3,739 degrees Celsius.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.

Here,
a. Let's start by defining a variable for the boiling temperature of zinc, which we'll call z.

According to the problem statement, the boiling temperature of platinum is 199 more than four times the boiling temperature of zinc. In other words,

Boiling temperature of platinum = 4z + 199

So the expression that represents the boiling temperature of platinum in degrees Celsius is:

4z+199

b. The problem tells us that the boiling temperature of zinc is 907 degrees Celsius. So we can substitute this value for z in our expression:

4z+199 = 4(907)+199 = 3,739

Therefore, the boiling temperature of platinum is 3,739 degrees Celsius.

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.

Answer:

0.03906square foot

Step-by-step explanation:

Given the dimension of the bedroom yo be 2.25in by 2.5in

First we need to convert to foot

2.25in = 0.08333×2.25 = 0.1875feet

2.5in = 0.08333×2.5 = 0.2083feet

Area of the rectangular bedroom = length × width

Area of the rectangular bedroom = 0.1875×0.2083

Area of the rectangular bedroom = 0.03906square foot

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:

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.

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.
