The value of 23 % of 42 is 9.7
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be A = 42
Now , let the percentage of the number A = 23 %
And , the equation will be
The 23 % of the number be = y
So , y = 23 % of 42
And , the equation is
y = ( 23 / 100 ) x 42
y = 0.23 x 42
On simplifying the equation , we get
y = 9.66
y ≈ 9.7
Therefore, the value of y is 9.7
Hence , The value of 23 % of 42 is 9.7

Un embalse estaba lleno a finales del mes de mayo. En el mes de junio se consumieron 3/10 de sus reservas y a finales de julio solo quedaba la mitad. ¿Qué fracción del embalse se consumió durante el mes de julio?
The English translation of the question is
A reservoir was full at the end of May. In the month of June 3/10 of its reserves were consumed and at the end of July only half remained. What fraction of the reservoir was consumed during the month of July?
Answer:
1/5 of the Reservoir will be consumed in the month of July.
Step-by-step explanation:
We are given
Full reservoir at the end of month May. In the month of June 3/10 of the reservoir was consumed.
Amount present in the Reservoir at the end of the month June will be = 1 -3/10
= 7/10
Now this 7/10 of the Reservoir will be used for the next month which is July
It is given that at the end of July only 1/2 of the Reservoir is remained that means the amount that was left at the end of the Month June will be used for the month July. So the amount consumed in the month of July will be
Amount consumed = 7/10 - 1/2
= 2/10 = 1/5
Therefore 1/5 of the reservoir will be consumed in the month of July.

therefore,
15-7=8
<3
Answer:
Add 7 to both sides of the equation
3 − 7 + 7 = 8 + 7
Simplify
3m = 8 + 7
3 = 1 5
Divide both sides of the equation by the same term
3 = 1 5
3 / 3 = 1 5 /3

Solve the following rational equation plz help!!
Answer:
x = [tex]\frac{9}{4}[/tex]
Step-by-step explanation:
Given
[tex]\frac{4x}{x+1}[/tex] - [tex]\frac{5}{x}[/tex] = [tex]\frac{4}{x^2+x}[/tex] ← factor denominator
[tex]\frac{4x}{x+1}[/tex] - [tex]\frac{5}{x}[/tex] = [tex]\frac{4}{x(x+1)}[/tex]
[ x ≠ 0, x ≠ - 1 as these would make the terms undefined ]
Multiply through by x(x + 1)
4x² - 5(x + 1) = 4
4x² - 5x - 4 = 4 ( subtract 4 from both sides )
4x² - 5x - 9 = 0 ← in standard form
(x + 1)(4x - 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
4x - 9 = 0 ⇒ 4x = 9 ⇒ x = [tex]\frac{9}{4}[/tex]
However, x ≠ - 1 for reason given above, then
solution is x = [tex]\frac{9}{4}[/tex]

Answer:
About 9.1 yards tall.
Step-by-step explanation:
So, we can draw the right triangle shown below:
We want to find h.
Since we know the angle and the side adjacent to the angle and we wan to find the opposite side, we will use the tangent ratio:
[tex]\displaystyle \tan(x^\circ)=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]
So:
[tex]\displaystyle \tan(20)=\frac{h}{25}[/tex]
Therefore:
[tex]\displaystyle h=25\tan(20)[/tex]
Use a calculator. Ensure your calculator is in the correct mode (degrees mode):
[tex]h\approx 9.1\text{ yards}[/tex]
The goal post is around 9.1 yards tall.

A soccer goal, as shows below, is composed of a pair of 8foot upright posts, positioned 48ft apart with a horizontal crossbar and netting boxing in the goal. A soccer ball is positioned directly in front of the right goal post. If the ground distance from the ball to the right goal is 14ft, what is the ground distance from the ball to the left goal post?
Answer:
The distance from the ball to the left post is 50 feet.
Step-by-step explanation:
Since a soccer goal is composed of a pair of 8 ft upright posts, positioned 48ft apart with a horizontal crossbar and netting boxing in the goal, and a soccer ball is positioned directly in front of the right goal post at a distance of 14ft, to To determine what is the ground distance from the ball to the left goal post, the Pythagorean theorem must be applied through the following calculation:
A ^ 2 = B ^ 2 + C ^ 2
A ^ 2 = 14 ^ 2 + 48 ^ 2
A ^ 2 = 196 + 2,304
A = √2500
A = 50
Thus, the distance from the ball to the left post is 50 feet.
