Answer:
6 niñas no practican ningún deporte.
Step-by-step explanation:
De un total de 24 niñas, [tex]\frac{1}{4}[/tex] practican natación. Esto se expresa mediante la operación matemática:
[tex]\frac{1}{4} *24[/tex]
Para multiplicar una fracción por un número entero, cualquier entero n puede ser escrito como la fracción [tex]\frac{n}{1}[/tex]. Entonces en este caso:
[tex]\frac{1}{4} *24=\frac{1}{4} *\frac{24}{1}[/tex]
Ahora se multiplican los denominadores para obtener el denominador final y se multiplican los numeradores para obtener el numerador final:
[tex]\frac{1}{4} *24=\frac{1}{4} *\frac{24}{1}=\frac{1*24}{4*1}=\frac{24}{4}[/tex]
Finalmente, se reduce el resultado hasta llegar a la forma más simple. Para obtener un resultado simplificado, se divide el numerador por el denominador. En este caso, para reducir la fracción [tex]\frac{24}{4}[/tex], se divide 24 por 4. El resultado obtenido es 6. Esto indica que de un total de 24 niñas, 6 practican natación.
Por otro lado, de un total de 24 niños, [tex]\frac{1}{2}[/tex] juegan voleibol. Esto se expresa mediante la operación matemática:
[tex]\frac{1}{2} *24[/tex]
Resolviendo de manera similar a lo previamente calculado, se obtiene:
[tex]\frac{1}{2} *24= 12[/tex]
Esto indica que de un total de 24 niñas, 12 practican voleibol.
Por lo que 6 niñas practican natación y 12 voleibol, siento un total de 18 niñas las que practican algún deporte. Por lo que la cantidad de niñas que no practican ningún deporte se calcula mediante:
24 niñas - 18 niñas que practican algún deporte= 6 niñas
6 niñas no practican ningún deporte.
De las 24 niñas consideradas, un total de 6 niñas no practican ningún deporte
How to add two fractions?Let we have to add two fractions as:
[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]
Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
Fraction of something shows how much of its part is being considered.
Thus, full part is 1/1 fraction. or simply 1.
Now, out of 24 girls, 1/4 practice swimming and 1/2 practice volleyball.
That means, out of 1 fraction of 24 , total (1/4 + 1/2) girls practice sports and rest doesn't.
[tex]\dfrac{1}{4} = \dfrac{1}{2} = \dfrac{1 + 1 \times 2}{4} = \dfrac{3}{4}[/tex]
So out of 1 fraction of 24, 3/4 practice sports and rest doesn't.
Rest of the girls who do not practice sports = 24's (1 - 3/4)th part
[tex]1 - \dfrac{3}{4} = \dfrac{4 \times 1 - 3}{4} = \dfrac{1}{4}[/tex]
Rest of the girls who do not practice sports = [tex]24 \times 1/4 = 6[/tex]
Thus, total 6 girls out of 24 girls considered do not practice any sports.

The population of Bengal tigers in a region of India can be modeled by the function P = 450(0.85), where P is the
population and I is the number of years since 2000.
What is the Bengal tiger population in 2000?
and by what percent does the tiger population decrease each year?
Answer:
(a) The population in 2000 is 450
(b) 15% decreases each year
Step-by-step explanation:
Given
[tex]P = 450(0.85)^t[/tex] --- since 2000
[tex]P \to Population[/tex]
[tex]t \to years[/tex]
Solving (a): The population in 2000
First calculate t
[tex]t = 2000 - 2000[/tex] --- years since 200
[tex]t = 0[/tex]
So, we have:
[tex]P = 450(0.85)^t[/tex]
[tex]P = 450 * 0.85^0[/tex]
[tex]P = 450 * 1[/tex]
[tex]P = 450[/tex]
Solving (b): Rate of population decrease
A function that decreases is represented as:
[tex]P(t) = a(1 - r)^t[/tex]
Where
[tex]r \to[/tex] rate of decrement
Compare [tex]P(t) = a(1 - r)^t[/tex] and [tex]P = 450(0.85)^t[/tex]
[tex]1- r = 0.85[/tex]
Collect like terms
[tex]r = 1 - 0.85[/tex]
[tex]r = 0.15[/tex]
Express as percentage
[tex]r = 15\%[/tex]

Find the solution of the system of equations.
15x -4y = -50
3x - 2y = -16
Answer:
15x - 4y =-50 -----(i)
3x - 2y=-16 --------(ii)
Using Substitution
From (i)
15x=4y-50
x=4y-50/15
Substitute x=4y-50/[15] into eqn (ii)
3x - 2y= -16
3[4y-50]/15 - 2y =-16
Multiply through by 15 to clear the fraction
3(4y - 50) - 30y=-240
12y - 150 -30y=-240
12y-30y=-240+150
-18y = -90
y=90/18
y=5.
Substitute into any eqn of choice to get x
3x - 2y=-16
3x - 2(5)=-16
3x - 10=-16
3x=-16+10
3x=-6
x=-6/3
x=-2.
x= -2
y=5

Applying the Pythagorean theorem, solve this triangle.
===================================================
Work Shown:
a = 60 and b = 80 are the two known sides
c is the unknown hypotenuse
Applying the pythagorean theorem gets us...
a^2 + b^2 = c^2
60^2 + 80^2 = c^2
3600 + 6400 = c^2
10,000 = c^2
c^2 = 10,000
c = sqrt(10,000)
c = 100
A quick way to see that 100 ft is the missing side is to note that a 6,8,10 right triangle scales up to 60,80,100 after multiplying all three sides by 10.
Or you could start with a 3,4,5 right triangle and multiply all three sides by 20.
Find three consecutive even integers such that the square of the first is 80 less than the square of the third. [Only an algebraic solution will be accepted.]
Answer:
First number = 19
Second consecutive = 20
Third consecutive = 21
Step-by-step explanation:
Assume;
First number = x
So,
Second consecutive = x + 1
Third consecutive = x + 1 + 1 = x + 2
So,
(x + 2)² - x² = 80
x² + 2(2)(x) + 2² - x² = 80
x² + 4x + 4 - x² = 80
4x + 4 = 80
4x = 80 - 4
4x = 76
x = 76 / 4
x = 19
First number = x
First number = 19
Second consecutive = x + 1
Second consecutive = 19 + 1
Second consecutive = 20
Third consecutive = x + 2
Third consecutive = 19 + 2
Third consecutive = 21
Avery is currently making $14 per hour at her job. Her boss gives her a 15% raise for showing good work ethic.
If she works 40 hours per week, how much more will Avery be making than before her 15% raise?
A.$15.00
B.$280.00
C.$84.00
D.$116.00
Answer:
C) $84
Step-by-step explanation:
40 x 14 = 560
she made $560 prior to raise
14 x 1.15 = 16.10
her new hourly rate is $16.10
40 x 16.1 = 644
she now earns $644 per week
644 - 560 = 84

This dot plot shows the number of runs scored by the yellow jackets in their last 12 baseball games
Answer:
Symmetric, If you fold the graph along the median, the point will almost match.
Step-by-step explanation:
The dot plot shows an approximately normal distribution with the peak being approximately in the centre and the tail shared to either sides of the peak. The median seem to reside at the centre of the distribution as well.
The median = 1/2(n+1)th term
n = 12
1/2(13)th term
Median = 6.5 term
Median = (6+6) /2 = 12/2 = 6
Which of these is a two-step equation? Ax + 9 = 21incorrect answer Bx = 11 + 2incorrect answer C2x + 9 = 21incorrect answer Dx/3 = 9
Answer:
2x + 9 = 21
Step-by-step explanation:
Looking at option C;
2x + 9 = 21
Step 1: Subtract 9 from both sides
2x+9 - 9 = 21 - 9
2x = 12
Step 2: divide both sides by 2
2x/2 = 12/2
x = 6
Hence the expression which is a two-step equation is 2x + 9 = 21 since we arrived at the solution in two steps

#2: Grace needs to buy a new printer. The printer she wants has a price tag of $60. She has a 25% off coupon and $50 in her bank account. If she must pay 6.75% sales tax, will she have enough money to buy the printer? If yes, how much will she have left over? If no, how much is she short?
Answer:
yes
Step-by-step explanation:
$60×25%=$15...so the coupon she have worth $15 but she also have $50
so she has an overall of $65 she can use
but she must pay sales tax:$60×6,75%=$4.05
so then the overall money that she must pay for the printer is $60+$4.05=$64.05
so then the difference of her money and the price of the printer is:
$65-$64.05=$0.95
$0.95 is left over

Find the approximant radius of a circle with a circumference of 34.48 inches. Use 3.14 for π Round to the nearest hundredth
Answer:
5.49 inches
Step-by-step explanation:
Given data
Circumference= 34.48inches
The expression for the circumference of a circle is
C= 2πr
Make r the subject of formula
r= C/2π
r= 34.48/2*3.14
r= 34.48/6.28
r= 5.49 inches
Hence the radius is 5.49 inches
