If each 4 in. on the scale drawing below equals 8 feet, what is the actual area of the shape in square units?
Answers
Answer:
the answer is 40 I donk know y
Answer: 384 ft. squared
Step-by-step explanation:
Hey!
So for this problem we first need to convert our scale lengths to feet. Since 4 in. equals 8 ft. that would make the 12 in side 24 ft. long because 12 divided by 4 is 3 and 3 time 8 is 24. We do this because we need to figure out how many times 4 inches are in each length because that how many time the 8ft is in the real length.
Next, we would do the same for the next side and divide 8 by 4 which is 2 and then we multiple 8ft by 2. We then get 16 ft which is our other side length.
After that, we just do our area formula which is length x width or in this case 16 x 24. This gets us 384 and then we add our unit and squared at the end and have our answer.
Hope this helped! :D

Which equation below does NOT represent a function of X A) x=y^2 B) y=x C) y = |x| D) y=x^2 E) y=1
Answers
Answer:
A) [tex]x = y^{2}[/tex]
Step-by-step explanation:
An equation is a function of [tex]x[/tex] when [tex]x[/tex] is the independent variable, that is:
[tex]y = f(x)[/tex] (1)
Where [tex]y[/tex] is the dependent variable.
According to this, [tex]x = y^{2}[/tex] does not represent a function of [tex]x[/tex], since the independent variable is a function of [tex]y[/tex], that is, [tex]x = f(y)[/tex]. Therefore, the correct answer is A.

1) One baseball team won 20 games throughout their entire season. Of all their games, this
team won 62.5% of them. Given this, how many games in total did this baseball team play
Answers
Answer: 32 matches
Step-by-step explanation:
Let the games in total that the baseball team played be represented by x.
Based on the information given in the question, we can form an equation as:
62.5% × x = 20
62.5/100 × x = 20
0.625 × x = 20
0.625x = 20
x = 20/0.625
x = 32
The team played a total of 32 matches.

En un videojuego, Marta ha conseguido 36.450 puntos capturando 11 monedas de oro. ¿ cuántos puntos vale cada moneda de oro?
Answers
Answer:
3313.64 puntos
Step-by-step explanation:
Podemos interpretar la pregunta anterior Matemáticamente como:
11 monedas de oro = 36.450 puntos
1 moneda de oro = x
Multiplicar cruzada
11 monedas de oro × x = 36.450 puntos × 1 monedas de oro
x = 36.450 puntos × 1 monedas de oro / 11
x = 3313.6363636 puntos
Aproximadamente
1 moneda de oro = 3313.64 puntos

The equivalent expression of [tex]w^{4} -36[/tex] is [tex](w^{2} -6)(w^{2} +6)[/tex].
What is equivalent expression?Equivalent expressions are expressions that work the same even though they look different.
According to the given question.
we have an expression [tex]w^{4} -36[/tex]
The equivalent expression of the above expression can be given by
[tex]w^{4} -36[/tex]
⇒ [tex](w^{2}) ^{2} -(6)^{2}[/tex]
⇒[tex](w^{2}-6)(w^{2} +6)[/tex] (by using the property [tex]a^{2} -b^{2} = (a-b)(a+b)[/tex] )
Hence, the equivalent expression of [tex]w^{4} -36[/tex] is [tex](w^{2} -6)(w^{2} +6)[/tex].
