What is the difference between math content and math skills

Answers

Answer 1
The concept is realizing that a common denominator makes adding fractions possible, since the units of the numerator then have the same value.

The skill is knowing how to make it happen-- knowing how to find the LCD, multiplying the top and bottom by the same amount to find the equivalent fractions, knowing that you add the numerators but don't change the denominators, and knowing how to reduce the resulting answer.

there are five united states athletes, four russian athletes, three french athletes, and one german athlete. How many rankings of the 13 athletes are there

Answers

Answer:

There are 6227020800  possible rankings

Step-by-step explanation:

Given

[tex]Athletes= 13[/tex]

Required

Number of Rankings

Let the number of athletes be n;

Since each athlete can only take one position at any given instance, the number of rankings is [tex]n![/tex]

Where [tex]n = 13[/tex]

Substitute 13 for n

[tex]13! = 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 *3 * 2 *1[/tex]

[tex]13! = 6227020800[/tex]

9/8m - 1/6m = -4 - 11/3

Answers

Answer:

m=-8

Step-by-step explanation:

im assuming the equation is: [tex]\frac{9}{8} m-\frac{1}{6} m=-4-\frac{11}{3}[/tex]

find common denominators i choose 24

9/8 = 27/24

1/6 = 4/24

11/3 = 88/24

4 = 96/24

now start solving:

(Note that because denominators are the same you can just ignore them and focus on the numerator)

simplify (27/24)m - (4/24)m to (23/24)m

simplify -(96/24) - (88/24) to -184/24

now you are left with 23/24 m = -184/24

get rid of denominators 23m=-184

Divide -184 by 23 to get m= -8

Point M is the midpoint of FG. Can the value of variable a be determined? Explain F(b+1, a+2). M(3,5). G(2a, 3b+3)

Answers

Answer:

YES, the value of a is 2

Step-by-step explanation:

Given the coordinates F(b+1, a+2, M(3,5) and G(2a, 3b+3), if M is the midpoint of F and G then, to get the value of a and b we will use the formula for calculating the midpoint a shown;

M(X, Y) = (x₁+x₂/2, y₁+y₂/2)

X = x₁+x₂/2 and  Y = y₁+y₂/2

From the given coordinates x₁ = b+1, y₁ = a+2, x₂ = 2a, y₂ = 3b+3, X = 3 and Y = 5

Substituting the given parameters into the formula, we can get the value of a and b as shown;

3 = b+1+2a/2

6 = 2a+b+1

2a+b = 5 ............... 1

Similarly, for the Y coordinate;

5 = a+2+3b+3/2

10 =  a+2+3b+3

a+3b = 10-2-3

a+3b = 5 ........ 2

Solving equation 1 and 2 simulatneously using elimination method

2a+b = 5 ............... 1 * 1

a+3b = 5 ........ 2 * 2

---------------------------------------------------------

2a+b = 5 ...........3

2a +6b = 10.......... 4

subtract 3 from 4

b - 6b = 5-10

-5b = -5

b = -5/-5

b = 1

substitute b =1 into equation 2 to get a;

a + 3b = 5

a + 3(1) = 5

a = 5-3

a = 2

From the calculation above it is seen that the value of variable a can be determined and it is equivalent to 2

Answer:

To determine the value of​ a, set up and solve a system of equations in two variables. The value of a is 2

Step-by-step explanation:

What are the coordinates of point B on AC such that the ratio of AB to AC is 1:3

Answers

Answer:

B) (2/3, 3 2/3)

Step-by-step explanation:

I think whoever write this problem thought the distance from A to C was 10.  It’s not.  It’s 10.77. (See below). But following what they did, the answer must be B) (2/3, 3 2/3)

First, find the distance from A to C.

4²+10²=c²

16+100=c²

116=c²

c=√116

10=10.77

The coordinates of point B on AC such that the ratio of AB to AC is 1:3 is (2/3, 3 2/3) option (B) is correct.

What is a segment bisector?

A segment bisector is a line, ray, line segment, or point that divides a line segment into two equal halves at its center.

It is given that:

The line segment shown in the picture is in the ratio of AB to AC is 1:3

AB : AC = 1 : 3

m : n = 1 : 3

The coordinate of point A is (2, 7)

The coordinate of point C is (-2, -3)

Let the coordinate of the point B is (x, y)

m = 1

n = 2

x1 = 2

x2 = -2

y1 = 7

y2 = -3

x = (-2+4)/3

x = 2/3

y = (-3+14)/3

y =11/3

y = 3 2/3

B = (x, y) = (2/3, 3 2/3)

Thus, the coordinates of point B on AC such that the ratio of AB to AC is 1:3 is (2/3, 3 2/3) option (B) is correct.

The options are:

A. (1/3, 2 5/6)

B. (2/3, 3 2/3)

C. (-2/3, 1 1/6)

D. (-2/3, 1/3)

Ann, Emily, and Bob collect stickers. They have a total of 70 stickers in the ratio 2:3:5, respectively. How many stickers does each child have?

Answers

Answer:

The stickers are divided by groups of

2/10, 3/10 and 5/10

2/10 * 70 = 14

3/10 * 70 = 21

5/10 * 70 = 35

14 + 21 + 35 = 70

So, the stickers are allotted to the 3 children in a group of

14 to one child, 21 to another child, and 35 to the third child.

Step-by-step explanation:

Bill has $6 more than Ted. Together they have $32. Write two equations and then solve for the amount of money that bill has.

Someone alr told me the was $19 but I NEED the equation part

Answers

Answer:

B= Bill's money

T= Ted's money

B+T=32

T+6=B

Step-by-step explanation:

If you rearrange the first equation you get:

B=32-T

You can then substitute the B in that equation with T+6:

T+6=32-T

combine like terms to get T:

2T+6=32

2T=26

T=13

Then plug in 13 for T in either of the first equations to get B:

13+6=B

19=B

Answer:

Bill has 19$

Step-by-step explanation:

Bill = b

Ted = t

b = t + 6$

b - t = 6$------equation 1

b + t = 32$------equation 2

(equation 1 - equation 2)

(b - b) + (-t - t) = 6 - 32

0 - 2t = -26

-2t = -26

t = -26/-2

t = -26/-2

t= 13$

(put t = 13$ in equation 1)

b - (13) = 6

b - 13 = 6

b = 6 + 13

b = 19$ (Bill = 19$)
