Answer:
15 teams, 4 girls and 3 boys on each team.
Step-by-step explanation:
What's the greatest common multiple of 60 and 45? It's 15.
This is the greatest number of teams that can be formed.
60/15 = 4; thus, there will be 4 girls on each team.
45/15 = 3; thus, 3 boys on each team
The greatest number of co-ed basketball teams that can be formed with an equal number of girls and boys is 3, with each team consisting of 4 girls and 3 boys.
To determine the greatest number of co-ed basketball teams that can enter the tournament with an equal number of girls and boys, you need to find the greatest common divisor (GCD) of the number of girls and boys. In this case, we have 60 girls and 45 boys. The GCD of 60 and 45 is 15, which means the largest number of teams that can be formed where each team has the same number of girls and boys is 15 (since 60 \/ 15 = 4 girls per team and 45 \/ 15 = 3 boys per team).
Answer 1: The greatest number of teams that can enter are 3 teams.
Answer 2: There would be 4 girls and 3 boys on each team.

A motorcycle dealer paid a certain price for a motorcycle and marked it up by 1/5 of the price he paid. Later, he sold it for $14. What is the original price?? PLZZ I will give you 100 pointd
Answer:
$11.67
Step-by-step explanation:
14 (the price he sold it for) = x + 1/5(x) (how much he upped the price)
14 = 6/5x
x = 11.67
To check find 20% of 11.67 which is 2.33 and add them together, which equals $14, so it checks out.
Answer:
$35/5 = $11.666666667 ≈ $11.67Step-by-step explanation:
A motorcycle dealer paid a certain price for a motorcycle
certain price = x
And marked it up by 1/5 of the price he paid.
marked price = 6/5x
Because x + 1/5x = 6/5x
Later, he sold it for $14.
6/5x = 14
1/5x = 14/6
x = 14/6 * 5
14 * 5 = 70
70/6 = 35/3
x = 35/3
x = 35/3 = $11.666666667
Substitute this back in to check it's right.
11.666666667 * 6/5 = 14

Complete the factorization of 3x2 – 10x + 8.
3x2 – 10x + 8 = (x –
)(
x – 4)
Answer:
We shall use the method of splitting the middle term
To factorize
3x² - 10 x + 8
We need two numbers which add to give -10 and multiply to give 3 × 8 = 24
The numbers are -6 & -4
(-6)+(-4) = -10
(-6)(-4) = 24
So we shall split -10x as -6x - 4x
We get
3x² -10x + 8
= 3x² -6x -4x+8
Taking out 3x common from first two terms & -4 from the lest two terms we get
= 3x(x-2)-4(x-2)
Taking out (x-2) common we get
= (x-2)(3x-4)
So
3x² - 10x + 8 = (x-2)(3x-4)

let f(x)=2/5x^2 -2. the function g(x) is a vertical stretch of f(x) by a factor of 2 what is the equation of g(x)?
Answer:
g(x) = 4/5 x² - 4
Step-by-step explanation:
∵ f(x) = 2/5 x² - 2
∵ f(x) stretched vertically by scale factor 2
∴ g(x) = 2[f(x)]
∴ g(x) = 2[2/5 x² - 2] = 4/5 x² - 4
The resulting function is g(x) = [tex]\( \frac{4}{5} x^2 - 4 \).[/tex].
Given the function f(x) = [tex]\( \frac{2}{5}x^2 - 2 \)[/tex] and the function g(x) representing a vertical stretch of f(x) by a factor of 2, we need to find the equation of g(x).
A vertical stretch of a function f(x) by a factor of k means multiplying the function by k. Here the factor k is 2.
So, the equation of g(x) will be:
g(x) = 2 * f(x)Substitute f(x) into the equation:
g(x) = 2 * [tex]( \( \frac{2}{5}x^2 - 2 \))[/tex]Distribute the 2:
g(x) = [tex]\( \frac{4}{5} x^2 - 4 \)[/tex]Therefore, the equation for g(x) after a vertical stretch by a factor of 2 is g(x) = [tex]\( \frac{4}{5} x^2 - 4 \)[/tex].

PLEASE HELP
QUESTION 1
If f(x)=1-x² and g(x)=1-x,
Then,
(f-g)(x)=f(x)-g(x)
This implies that,
[tex]( f - g)(x) = 1 - {x}^{2} - (1 - x)[/tex]
[tex]( f - g)(x) = 1 - {x}^{2} - 1 + x[/tex]
We simplify to get,
[tex]( f - g)(x) = - {x}^{2} + x[/tex]
The correct choice is B.
QUESTION 2
Given:
f(x)=3+x
and
[tex]g(x) = {x}^{2} + 1[/tex]
[tex](f\circ g)(x)=f(g(x))[/tex]

[tex](f\circ g)(x)=3 + {x}^{2} + 1[/tex]
[tex](f\circ g)(x)= {x}^{2} +4[/tex]
Also,
[tex](g\circ f)(x)=g(f(x))[/tex]
[tex](g\circ f)(x)=g( 3+ x)[/tex]
[tex](g\circ f)(x)= {(3 + x)}^{2} + 1[/tex]
[tex](g\circ f)(x)= 9 + 6x + {x}^{2} + 1[/tex]
[tex](g\circ f)(x)= {x}^{2} + 6x + 10[/tex]
A local grocer cut his marketing budget by 57% last year. He spent only $650 on marketing this year and is happy with his decision. How much did the grocer spend on marketing last year?
I know that the answer is $1511.63, I just need to know the math of how we get that answer.
To find out how much the grocer spent on marketing last year, we need to set up an equation with x as the original budget. By solving the equation, we find that the grocer spent approximately $1511.63 on marketing last year.
Explanation:To find out how much the grocer spent on marketing last year, we first need to determine the original marketing budget. Since the grocer cut their marketing budget by 57%, this means they spent only 43% of their original budget this year. Let's represent the original budget as 'x'.
Set up an equation: 43% of x = $650Convert 43% to decimal form by dividing by 100: 0.43x = $650Solve for x by dividing both sides of the equation by 0.43: x = $650 / 0.43Calculate the value of x using a calculator or long division: x ≈ $1511.63Therefore, the grocer spent approximately $1511.63 on marketing last year.

What angle in the first quadrilateral corresponds to J?
A

C
D
Answer:
A
Step-by-step explanation:
With this question, its actually way easier than you think. If you want to find corresponding angles, you have to find a way to make the shapes overlap to be exactly the same. If they cannot be exactly the same, there will not be corresponding angles. For this, if you rotate quadrilateral 90 degrees counter-clockwise, you will see that the shapes look the same. Then you can just match up the angles that have the same degree measure (or just look the same for simplicity) and you have your answer. The answer is actually in the question too. ABCD=JKLM, but each letter is actually in the right place. A=J B=K C=L D=M.

A scale on a blue print drawing of a house shows that 666 centimeters represents 333 meters. What number of centimeters on the blue print represents an actual distance of 272727 meters?''
Answer:
545454
Step-by-step explanation:
This is a ratio. you take 666/333 = x/272727. Basically tis says 666 cm to 333 m is equal to some number of centimeters to 272727 meters. Then just solve for x. 272727(666/333) = 545454.
Another way of looking at it is what did we multiply 333 by to get 666. Answe is 2, so we do the same for 272727. 2*272727 = 545454
If you wanted to you could have also converted units so everything was in either centimeters of meters, but as long as you keep things in the right order this works.
Answer: the number of centimetres is 54cm
Step-by-step explanation:
Given that 6 centimeters represents 3meters.
The number of centimeters on the blue print that will represent an actual distance of 27meters will be Y
6 : Y = 3 : 27
That is
6/Y = 3/27 = 1/9
Cross multiply
Y = 54 cm

Raeana is twice as old as Madeline, and Laura is 10 years older than Raena. If Laura is 50 years old, how old is Madeline? Define your variables.
Answer: Madeline is 20 yrs old
Step-by-step explanation:
If Laura is 50 and she is 10 years older than Raena then Raena is 40 that would then make Madeline 20 years old.
Final answer:
To determine Madeline's age, we set up an equation based on the given relationship and solved it to find that Madeline is 20 years old.
Explanation:
To solve the question about Raeana, Madeline, and Laura's ages, we first define the variables. Let's denote Madeline's age as M. Since Raeana is twice as old as Madeline, Raeana's age would be 2M.
The problem states that Laura is 10 years older than Raeana, making Laura's age 2M + 10. Given that Laura is 50 years old, we can set up an equation: 2M + 10 = 50.
Now, we solve for M:
Subtract 10 from both sides of the equation to isolate the term with M on one side: 2M = 40.
Divide both sides by 2 to solve for M: M = 20.
Therefore, Madeline is 20 years old.

All rectangles are parallelorams.Are all parallelograms rectangles? Explain
Answer:
See explanation
Step-by-step explanation:
Definitions of parallelogram and rectangle:
A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.
A rectangle is a parallelogram with four right angles.
This gives us that each rectangle is a parallelogram.
But an arbitrary parallelogram can have angles that are not necessarily right (for example, 60°, 120°, 60°, 120°). Thus, there are a lot of parallelograms that are not rectangles.

The length of a chord is equal to its distance to the center of the circle. A second chord in the same circle is twice as long as the first one. How far is the second chord from the center?
Answer:
The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.
Step-by-step explanation:
The length of the chord AB is the same as the distance OC from the center to the cord. Let OC=2x, then CA=x. By the Pythagorean theorem, the radius r of the circle is
[tex]r^2=OC^2+AC^2,\\ \\r^2=(2x)^2+x^2=5x^2,\\ \\r=\sqrt{5}x.[/tex]
The length of the arc ED is 4x.
Consider right triangle EFO. In this triangle, EF=2x, EO=r, then the distance OF is
[tex]OF^2=OE^2-EF^2,\\ \\OF^2=5x^2-(2x)^2=x^2,\\ \\OF=x.[/tex]
The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.
The distance between the second chord from the center of the circle is 'a' (half the length of the first chord).
What is a chord?A circle chord is a straight line segment with both endpoints on a circular arc.
As the length of a chord is equal to its distance to the center of the circle, therefore, the length of the chord and the distance to the center of the circle is 2a. Thus, In ΔAOB the length of the third side of the triangle can be written as,
[tex]OA^2= OB^2+AB^2\\\\OA^2 =(2a)^2+a^2\\\\OA^2=5a^2\\\\OA = a\sqrt5[/tex]
Now, OA and OQ are the radii of the circle and the length of the radius of the circle is a√5 units.
Now, the length of the second chord in the same circle is twice as long as the first one, therefore, the length of the half chord is 2a. Therefore, in ΔAOB the length of the perpendicular side of the triangle can be written as,
[tex]OQ^2=OP^2+PQ^2\\\\(a\sqrt5)^2= OP^2+(2a)^2\\\\5a^2-4a^2=OP^2\\\\OP = a[/tex]
Hence, the distance between the second chord from the center of the circle is 'a' (half the length of the first chord).
