carlos es un arquitecto y esta construyendo una casa si ha construido 3/7 de la casa le falta para acabarla es lo mismo que llegar a 7/7
Answer:
Ok, sabemos que Carlos ha construido un 3/7 de una casa.
Queremos saber cuanto le falta para terminar de construirla.
Entonces podemos realizar el cálculo:
1 casa - lo que Carlos ya construyo = Lo que le falta.
Entonces:
1 casa - 3/7 de una casa = X
Podemos reescribir:
1 casa = 7/7 de una casas
así tenemos:
7/7 de una casa - 3/7 de una casa = X
(7/7 - 3/7) de una casa = X
4/7 de una casa = X
Así podemos concluir que a Carlos le falta construir 4/7 de una casa para acabar.

For a field trip 29 students rode in cars and the rest filled seven how many students were in each bus if 379 students were on the trip?
Answer:
50 students per bus
Step-by-step explanation:

Erica has 1 5/8 cups of yogurt to make smoothies. Each smoothie uses 1/3 of a cup of yogurt. What is the maximum number of smoothies that Erica can make with the yogurt?
Answer:
4 smoothies.
Step-by-step explanation:
We divide 1/3 into 1 5/8 ( which is 13/8).
= 13/8 / 1/3
= 13/8 * 3
= 39/8
= 4 7/8
Maximum number = 4.

Find the surface area
please show work
Answer:
Step-by-step explanation:
The pentagon faces are made up of five triangle each with 9 ft bases and 6.2 ft heights. And there are five rectangular sides of 9 by 5 feet. So the total surface area is
A=2*5*9*6.2/2+5*9*5
A=279+225
A=504 ft^2
Answer:
Formula: nl(b + h) it is derived as well
504 ft²
Step-by-step explanation:
Each vertical face is a rectangle.
Area of each face = length x breadth = lb
For n-sided polygon, area of vertical faces = n x lb = nlb
For horizontal faces:
Observe: you can actually divide that face in 5 right-angled triangle(two edge point & centre form right angled ∆). [For n-sided, that's n right angled ∆]
For 2 such faces, you have 2 x n times of area of 1 ∆.
Area of 2n∆ = 2n( ½ x h x base(length)) = nhl
Total area = area of horizontal surfaces + area of vertical surfaces
Total area = nlb + nhl = nl(b + h)
Total area = 5*9(5 + 6.2) = 504 ft²

Cynthia wants to know the favorite band of all 5th graders in her school. She asks 10 of her friends from the 5th grade Art Club.
How would you describe this sample?
Question 8 options:
This is a valid sample since she only asked 5th graders.
This sample is valid because it is a Simple Random Sample.
This sample is invalid because it is a Systematic Random Sample.
This sample is invalid because it is a Convenience Sample.
I think this is invalid because it is a convenience sample. All of the 5th graders she asked were her friends, and they were all in the art club.

After substituting, what is the first step when evaluating
4y+9
____
7 when Y = 87
Answer:
The "first step" is the multiplication of 4 and 87
Step-by-step explanation:
I'll assume that you actually meant 4y + 97. If you substitute 87 for y, you get 4(87) + 97. The "first step" is the multiplication of 4 and 87:
348 + 97, or
445
Find the midpoint of A and B where A has coordinates (-3,-5) and B has coordinates (4,4).
Brainliest if you want :)
Use the midpoint formula,
[tex]\left( \dfrac{x_1+x_2}{2} , \dfrac{y_1+y_2}{2} \right)[/tex]
where x₁ = -3, x₂ = 4, y₁ = -5, and y₂ = 4.
[tex]\left( \dfrac{x_1+x_2}{2} , \dfrac{y_1+y_2}{2} \right) \implies \left( \dfrac{-3+4}{2} , \dfrac{-5+4}{2} \right) = \left(0.5, -0.5\right).[/tex]
So, the midpoint of A and B is (0.5, -0.5). It should be in the first quadrant.

Log 8 1/32 is equaled to
Answer:
I think the answer wold be -5/3 or -1.666666667 .
The value of the given expression is,
[tex]log_8 \frac{1}{32}[/tex] = -3/5
The given logarithmic expression is,
[tex]log_8 \frac{1}{32}[/tex]
Since we know that,
The power to which a number must be increased in order to obtain additional values is referred to as a logarithm. The easiest approach to expressing enormous numbers is this manner. Numerous significant characteristics of a logarithm demonstrate that addition and subtraction logarithms may also be represented as multiplication and division of logarithms.
We can write the given expression as,
[tex]log_8 \frac{1}{32}[/tex] = [tex]log_8 32^{-1[/tex]
= - [tex]log_8 32[/tex] [ [tex]log_a b^x = x log_a b[/tex]]
= - [tex]log_{2^3} 2^5[/tex]
= - [tex]\frac{3}{5} log_{2} 2[/tex] [ [tex]log_{a^y} b^x = \frac{x}{y} log_a b[/tex]]
= -3/5 [ [tex]log_{a} a = 1[/tex]]
Hence,
[tex]log_8 \frac{1}{32}[/tex] = -3/5
