Un cubo tiene una superficie de 54 cuadrados. Metros. ¿Cuál es el volumen del cubo en ¿metros cubicos?
Answer:
27 cubic meters
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Area of cube = 54 square meters
Let, Side = a
Then, Area of cube = 6[tex]a^{2}[/tex]
54 = 6 [tex]a^{2}[/tex]
[tex]a^{2}[/tex] = 9
a = 3
So, we can calculate the volume of cube by using following formula
Volume of cube = [tex]a^{3}[/tex]
By putting the value in the formula, we get
Volume of the cube = [tex]3^{3}[/tex]
= 27 cubic meters

So I have already solved this problem but I don’t really understand how I solved it if anyone could help me I would really appreciate it!
If the interest for 3 months is $260, then the total interest for the year is 4 times $260 or $1040.
Let x = amount invested at one of the rates, say 6%. This leaves the rest of the $16,000 or (16000-x) to be invested at the other rate, at 8%.
The equation is basically that the interest earned for 1 year at 6% plus the interest earned for the year at 8% is equal to the total interest for the year, or $1040.
.06x + .08(16000-x) = 1040
.06x + .08(16000) - .08x = 1040
-.02x + 1280 = 1040
Subtract 1280 from each side:
-.02x = 1040 - 1280
-.02x = -240
To solve for x, divide both sides by -.02, remembering that a negative divided by a negative is a negative.
x = 240/.02
Either divide with a calculator, or multiply numerator and denominator by 100 to eliminate the decimal.
x = 24000/2 = $12000 at 6%
16000-x = 16000-12000 = $4000 at 8%

95 - 3/4 what is the value of the expression
Answer:377 /4 = 94 and 1 / 4 =94.25
Step-by-step explanation:
Subtract
95 − 3 /4
= 377 / 4
Convert integer to fraction
95 = 95 / 1
Find common denominator
95 over 1
− 3 over 4
= ( 95 × 4 ) over ( 1 × 4 )
− ( 3 × 1 ) over ( 4 × 1 )
= 380 over 4
− 3 over 4
4 is the least common multiple of denominators 1 and 4. Use it to convert to equivalent fractions with this common denominator.
Subtract
380 over 4
− 3 / 4
= ( 380 − 3 ) / 4
= 377 /4
Simplify
377 / 4
= 94 and 1 /494
Reduce fraction to lowest terms
1 is the greatest common divisor of 377 and 4. The result can't be further reduced.
Step 2 of 2: Simplify, sub-step b: Convert improper fraction to mixed number.
Convert improper fraction to mixed number
377 /4
= 94 1 /4
377 ÷ 4 = 94 remainder 1
By writing the whole number as a fraction, we will see that the solution is 377/4
How to solve the expression?
Here we want to take the difference between a whole number and a fraction:
95 - 3/4
To do this, we need to write the whole number as a fraction, to do it, we multiply and divide it by 4:
95 = (4/4)*95 = 380/4
Now we rewrite our expression as:
95 - 3/4 = 380/4 - 3/4 = 377/4
This is the solution of the expression.

The equation of proportion is y equals 2 over 9 x and , y = ( 2/9 )x
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
where y varies directly with x, and y is 16 when x is 72
So , when x = 72 , y = 16
y = kx
16 = k ( 72 )
Divide by 72 on both sides , we get
k = 16 / 72
k = 2/9
Therefore , the value of A is y = ( 2/9 )x
Hence , the equation is y = ( 2/9 )x

Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circle.
Given and ,
° and
°.
Answer:
146°
Step-by-step explanation:
Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circle. Given m arch AB=64° and ⦣ABC=73°, m ⦣ABC=__ ° and m arch AC=__ °.
Solution:
Given that:
arc AB = 64° and ⦣ABC=73°
The Central Angle Theorem states that the central angle from two chosen points A and B on the circle is always twice the inscribed angle from those two points. The inscribed angle is any point along the outer arc AB and the two points A and B.
Therefore arc AC is the central angle of ⦣ABC. Using the central angle theorem gives:
arc AC = 2 * ⦣ABC
substituting:
arc AC = 2 * 73
arc AC = 146°

Answer:
Q1: 18 degrees
Q2: 60 sides
Step-by-step explanation:
The sum of the exterior angles is always 360 degrees. With this, do 360/20 to get the amount of sides that are within the shape.
360/20 --> 18 degrees.
Now with the interior angles, it can be found with the equation ((n-2) * 180 degrees) / n = Angle Given. With this, plug 174 degres into your equation.
(n-2) * 180 degrees) / n = Angle Given
(n-2) * 180 degrees) / n = 174
180n -360 / n = 174
180n -360 / 174n
360 = 6n
n = 60
It would be 60 sides.
