Step-by-step explanation:

This excercise, focuses on ratio problem, and it has to do with the representation of ratio, since we can represent ratio in different ways. let us represent this ratio in the normal/ usual format.

we will first reduce the given value and represent it in the ratio format

given that for  roller skate race, 48 are boys and,

roller skate race, 64 are girls

we have the ratio as

=48/64 divide both denominator and numerator by 4

=12/16  further divide both denominator and numerator by 4

=3/4

The ratio is 3:4

The required evaluation of a - c when a = 20.9 and c = 12.8 is 33.7. Option A is correct.

Given that,
To evaluate a - c when a = 20.9 and c = -12.8.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The given expression,
= a - c
a = 20.9 and c = -12.8.
= 20.9 - (-12.8)
= 20.9 + 12.8
= 33.7

Thus, the required evaluation of a - c when a = 20.9 and c = 12.8 is 33.7. Option A is correct.

Answer:

First one: Even

Second one: Neither

Third One: Odd

Fourth One: Neither

Step-by-step explanation:

The functions are:

a) f(x) = x² + 9 is neither even nor odd.

b) g(x) = |x - 3| is neither even nor odd.

c) f(x) = x is an odd function.

d) g(x) = x + x² is neither even nor odd.

Here, we have,

To determine whether each function is even, odd, or neither, we examine their symmetry properties under reflection about the y-axis (for even functions) and the origin (for odd functions).

Let's analyze each function:

a) f(x) = x² + 9

This function is neither even nor odd because it does not satisfy the properties of symmetry under reflection about the y-axis or the origin.

b) g(x) = |x - 3|

This function is neither even nor odd because it does not satisfy the properties of symmetry under reflection about the y-axis or the origin.

c) f(x) = x

This function is odd because it satisfies the property of symmetry under reflection about the origin. In other words, f(-x) = -f(x) for all x.

d) g(x) = x + x²

This function is neither even nor odd because it does not satisfy the properties of symmetry under reflection about the y-axis or the origin.

In summary:

a) f(x) = x² + 9 is neither even nor odd.

b) g(x) = |x - 3| is neither even nor odd.

c) f(x) = x is an odd function.

d) g(x) = x + x² is neither even nor odd.

3 students split (division) 2 less (subtraction) than the number of pencils (p)

Answer:

p = -2

Step-by-step explanation:

5p - 10 = + 4(1 + 3p)

first get rid of the bracquetes:

5p - 10 = + 4*1 + 4*3p

5p - 10 = + 4 + 12p

subtract left and right of = sign by 5p

5p -5p - 10 = + 4 + 12p -5p

0 - 10 = + 4 + (12p -5p)

subtract left and right of = sign by 4

-10 -4 = 4 -4 + ( 7p )

re arrange

7p + 0 = -14

divide left and right of = sign by 7

7/7 p = -14/7

HAVE A GOOD DAY!

First, we need a few things.

The first term = 26

The common difference = 22 - 26 = -4

26 - 4(n - 1) is our equation.

Let's plug 50 into n to find a50

a50 = 26 - 4(50 - 1)

a50 = 26 - 4(49)

a50 = 26 - 196

8. -1

9. 28

10. 24

Step-by-step explanation:

substitute values into equations. don't forget the brackets :))

7. 3x + 2y2 Let x = 4, y = 3

= 3(4) + 2(3)2

= 12 + 12

= 24

8. (x + 2)2 - (3x - 2) - 4 Let x = 3

= ((3) + 2)2 - (3(3) - 2) - 4

= (5)2 - (9 - 2) - 4

= 10 - 9 + 2 - 4

= -1

9. x + 2y - 3z + xyz Let x = 4, y = 3, z = 2

Answer:

y=-5/2x+(Any number)

Step-by-step explanation:

First, find the slope of that line

3+2=5

-5+7=2

5/2 is the slope

Perpendicular lines have the slope that is opposite and a fliped sign

This means that the slope should be -2/5

The equation of the line would be y=-5/2x+(Any number)

Answer:

96,000

Step-by-step explanation:

.8 x 120,000 = 96,000

mueves el decimal sobre el porcentaje que deseas encontrar, luego lo multiplicas por el total. por ejemplo quiere 80% entonces mueves el decimal para que sea .8 o si quierias 55% entonces es .55 y el total es el 120,000 el numero que tienes. (:

Answer:96000

Step-by-step explanation:

120000/x=100/80

(120000/x)*x=(100/80)*x       - we multiply both sides of the equation by x

120000=1.25*x       - we divide both sides of the equation by (1.25) to get x

120000/1.25=x  

96000=x  

x=96000

Answer:

4

Step-by-step explanation:

First n(AUB)=n(E) - n((AUB)')

So n(AUB) = 40 - 6 = 34

Now all u hv to do is use the formulae,

n(AUB) = n(A) + n(B) - n(ANB)

So when u substitute above values,

34=22 + n(B) - 8

So,

n(B) = 4

Answer:

18

Step-by-step explanation:

Product in math terms means to multiply

When the term "a number" is used, you can just put a variable

"Is," tells you what the problem equals

With this information, we can create the equation:

(2/3x) + 6 = 12

Now that we have this equation, we can solve it

(2/3x) +6 = 12            We can subtract 6 from both sides.  

            -6     -6

2/3x = 12                   We can divide the 2/3 from each side.

/2/3         /2/3

x = 18

Hope this helps!

Answer:

1

Step-by-step explanation:

2/3x + 12 = 6

2/3x = -6

x = -6 divided by 2/3

(6 divided 2) divided 3 =1
