In a softball league, the male to female ratio is 5:6. If there are 165 members in the league, how many females are in the league?
Answer:
138
Step-by-step explanation:
The total number of females are in the softball league, when there is total 165 members are there in the league is 138.
What is the ratio of two numbers?The ratio of two number is the fraction part, which represent that how a number is more or less compare to the other.
In a softball league, the male to female ratio is 5:6. It can be represented as,
[tex]r=\dfrac{5}{6}[/tex]
This means there are 5 males on 6 females. There are a total number of members in the league is 165. Then the number of females in the league is,
[tex]n=\dfrac{165\times5}{6}\\n\approx 138[/tex]

Answer:
58%
Step-by-step explanation:
Lo siento. No soy bueno con el español, así que estoy usando translate. Espero que esté bien.
Entonces, para esta ecuación, usaremos un porcentaje igual o superior a 100 como se indica aquí. ([tex]\frac{es}{de}[/tex] = [tex]\frac{porciento} {100}[/tex]) Entonces tu ecuación es [tex]\frac{28}{49}[/tex] = [tex]\frac{x}{100}[/tex]
Multiplicará 28 por 100, lo que le dará 2800. Luego, dividiría 2800 entre 48, lo que le daría 58. Entonces, su respuesta sería x = 58%.

Matt and Ash are selling fruit for a school fundraiser. Customers can buy small boxes of fruit or
large boxes of fruit. Matt sold 3 small boxes and 5 large boxes for a total of $47. Ash sold 11 small
boxes and 10 large boxes for a total of $114. What is the cost of a small box of fruit?
Answer: The cost of a small box is $4. The cost of a large box is $7.
Step-by-step explanation:
Let s = cost of a small box and L = cost of a large box
3s + 5L = 47
11s + 10L = 114
Multiply the top equation by -2 to combine with the second equation
-6s - 10L = -94
+11s +10L = 114
L cancels out, now solve for s
5s = 20
s = 4
Now, plug the value of s back into an equation to find the value of L
3(4) + 5L =47
12 + 5L = 47
5L = 35
L = 7

Step-by-step explanation:
Given that 3 feet equal 1 yard, how many yards
equal 7 feet?
Answer:
7/3
Step-by-step explanation:
because 3/7 is less then two
The correct option is B. 7/3
Given that 3 feet equal 1 yard, to find out how many yards equal 7 feet,
To convert a length in feet into yards, we need to use the conversion factor that states 1 yard is equal to 3 feet. If a length of "a" feet, you can convert it into yards by dividing "a" by 3.
For example, convert 12 feet it into yards.
Using the conversion factor, set up the proportion:
3 feet / 1 yard = 12 feet / s yards
To find the value of "s," by cross-multiplication
3 feet x s yards = 12 feet x 1 yard
3s = 12
Dividing both sides of the equation by 3:
s = 12/3
s = 4
Thus, 12 feet is equal to 4 yards.
Set up a proportion using the ratio of feet to yards.
Let "x" represent the unknown number of yards that is equivalent to 7 feet. The proportion can be written as:
3 feet / 1 yard = 7 feet / x yards
To solve for "x," by cross-multiplication,
3 feet x x yards = 7 feet x 1 yard
3x = 7
Dividing both sides of the equation by 3:
x = 7/3
So, 7 feet is equal to 7/3 yards, which can also be expressed as 2 and 1/3 yards or approximately 2.33 yards.
Therefore, 7 feet is equivalent to 7/3 yards.
Hence, the correct option is B. 7/3

Answer:
does this help?
Step-by-step explanation:
PR=9+4+36−−−−−−−−√=7
PQ=36+9+4−−−−−−−−√=7
RQ=1+25+64−−−−−−−−−√=98−−√
PQ2+RQ2=49+49=98
As the triangle satisfies the Pythagoras's theorem, it is a right angled triangle.
What is Pythagoras Theorem?According to Pythagoras Theorem, in a right angled triangle the square of the side opposite to the right angle is equal to the sum of squares of the other two sides.
Height² + Base² = Hypotenuse²
For a triangle to be a right triangle, it should satisfy Pythagoras's Theorem.
The length of the sides of the triangle will be determined using Distance formula.
PQ² = ( 3 - (-4))² + (5-0)²
PQ² = 49 + 25
PQ² = 74
QR² = ( 8 - 3)² + (-2-5)²
QR² = 25 + 49
QR² = 74
RP² = (-4 - 8)² + ( 0 +2)²
RP² = 144+4
RP² = 148
Now checking for Pythagoras theorem,
148 = 74 +74
148 = 148
RP² = PQ²+QR²

Which graph represents the equation below?
Answer:
c
Step-by-step explanation:
we can see that the "a" value is -1, written as just "-" meaning the parabola is going to face down, this eliminates A and D, then if we solve for the x intercepts, ( set the values in the parenthesis equal to 0) we see that the intercepts are negative one and positive 3
The graph which represents the equation f(x) = -(x + 1)(x - 3) is graph C.
Given a function that has the equation form:
f(x) = -(x + 1)(x - 3)
It is required to find the graph of this function.
The equation is clearly in the form of a factorized quadratic equation.
So the graph will be clearly parabola.
Now, when the equation is expanded, the equation will be of the form:
f(x) = -(x² -2x -3)
= -x² + 2x + 3
The leading coefficient is negative. So the parabola opens downward.
This eliminates options A and D.
The remaining options are B and C.
From the factored form, the zeroes of the function are:
-(x + 1)(x - 3) = 0
(x + 1)(x - 3) = 0
x = -1 and x = 3
That is, the graph touches the X-axis at x = -1 and x = 3.
The vertex coordinates are:
x = -b/2a = -2/-1 = 1
y = f(-b/2a) = -(1+1)(1-3) = 4
Hence the correct option is C.

Given a complex number a + bi and its conjugate a - bi , a, b ∈ R, then the product is
(a + bi)(a - bi) ← expand using FOIL
= a² - abi + abi - b²i² [ i² = - 1 ]
