A sum of money is to be divided among three girls, Anna, Barbara and Chrissy in the ratio 5 : 3 : 2. If Barbara received $400 less than Anna, calculate the amount of money each girl received.

Answers

Answer 1

Answer:

Anna received $1000

Barbara received $600

Chrissy received $400

Step-by-step explanation:

Let us solve the problem

∵ The ratio of Anna, Barbara, and Chrissy is 5: 3: 2

∵ Barbara received $400 less than Anna

→ That means Anna - Barbara is 400, find the difference between their ratio

∵ The difference between their ratio = 5 - 3 = 2  

→ By using the ratio method

→  Anna  :  Barbara  : difference

→  5        :  3              :  2

→  A        :  B             :  400

→ By using the cross multiplication

A × 2 = 5 × 400

∴ 2A = 2000

→ Divide both sides by 2

A = 1000

Anna received $1000

∵  B × 2 = 3 × 400

∴ 2B = 1200

→ Divide both sides by 2

B = 600

Barbara received $600

Let us use the ratio between Anna and Chrissy to find the amount of Chrissy

→  Anna  :  Chrissy

→  5        :   2

→  1000  :   C

→ By using cross multiplication

5 × C = 2 × 1000

∴ 5C = 2000

→ Divide both sides by 5

C = 400

Chrissy received $400

What’s 25 dived by 9 in long (step by step)

Answers

Answer:

Step 1:

Start by setting it up with the divisor 9 on the left side and the dividend 25 on the right side like this:

           

   9 ⟌ 2 5  

Step 2:

The divisor (9) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

       0    

   9 ⟌ 2 5  

Step 3:

Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend.

       0    

   9 ⟌ 2 5  

       0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

       0    

   9 ⟌ 2 5  

     - 0    

       2    

Step 5:

Move down the 2nd digit of the dividend (5) like this:

       0    

   9 ⟌ 2 5  

     - 0    

       2 5  

Step 6:

The divisor (9) goes into the bottom number (25), 2 time(s). Therefore, put 2 on top:

       0 2  

   9 ⟌ 2 5  

     - 0    

       2 5  

Step 7:

Multiply the divisor by the result in the previous step (9 x 2 = 18) and write that answer at the bottom:

       0 2  

   9 ⟌ 2 5  

     - 0    

       2 5  

      1 8  

Step 8:

Subtract the result in the previous step from the number written above it. (25 - 18 = 7) and write the answer at the bottom.

       0 2  

   9 ⟌ 2 5  

     - 0    

       2 5  

     - 1 8  

         7

Which is a fourth degree trinomial with a leading coefficient of 3?
A) x2 – 3x4 + 13x
B) 3x4 – 8x3 = x + 2
C) 3x3 – x2 =12
D) x - x2 + 3x4​

Answers

Answer:

B.

Step-by-step explanation:

A fourth-degree trinomial with a leading coefficient of 3 is (B) [3x⁴-8x³=x+2].

What is a trinomial?A trinomial in elementary algebra is a polynomial made up of three terms, or monomials.An algebraic expression with three non-zero terms is called a trinomial. Trinomial expression examples: A trinomial with the variables x, y, and z is x + y + z.A trinomial in one variable, 2a² + 5a + 7, exists.

So, we know that a trinomial is made up of 3 terms.

4th-degree trinomial means that it has a power of 4.And with a coefficient of 3.

So, such expression is: 3x⁴ - 8x³ = x + 2

Therefore, a fourth-degree trinomial with a leading coefficient of 3 is (B) [3x⁴ - 8x³ = x + 2].

can someone solve x - 8 = -3x + 12

adding 8 and 3x on both sides

x-8+8+3x= -3x+3x+12+8

x=5

x+12= -x-6

adding x and subtacating 12 on both sides

Then subtract 6 on both sides

3x = 9

Now divide by 3 to isolate x to get...

x = 3

5x + 6 = 2x + 15
5x + 2x = 6 + 15

The given equations are

32x + 12y = 420 .....2

Multiplying equation 1 by 3 to make  coefficient of y same we have:

36x+12y= 456

32x+12y=420

Subtracting the two equations we have:

4x=36.

Dividing by 4 both sides  

x= 9.

Substituting x value in equation 1

12(9) + 4y = 152

108+4y=152

Subtracting 108 both sides: 4y=44.

Dividing both sides by 4.

y=11.

Answer:

The correct answer is:

Option 2: Yes, because the slopes of lines are negative reciprocals.

Step-by-step explanation:

Given equations of lines are:

Line p: x+2y=1

Line q: y=2x+1

We can determine if two lines are parallel or perpendicular by comparing the slopes of line.

Slope intercept form of line is given by the formula

[tex]y = mx+b[/tex]

Equation of line q is already in slope intercept form.

We have to convert the equation of line p in slope-intercept form

[tex]x+2y = 1\\2y = -x+1\\2y = -\frac{1}{2}x+\frac{1}{2}[/tex]

Slope of line p = 2

Slope of line q = -1/2

We can see that

[tex]2.-\frac{1}{2} = -1[/tex]

The product of slopes of both lines is -1, hence, the lines are perpendicular.

Hence,

The correct answer is:

Option 2: Yes, because the slopes of lines are negative reciprocals.

If f(1) = 5 and f(n) = 5f(n − 1) then find the value of f (5).

Answers

Answer:

f(1)= 5

so x=1

f(5)= 5(5-1) = 20

The value of f(5) is 3125.

What is Function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

f(1) = 5 and f(n) = 5f(n − 1)

Now, for finding the the 5 th term we have to find the remaining four term before the 5th term.

So, n=2

f(2) = 5f(1)

f(2)=  5(5)

f(2)=  25

Now, n=3

f(3) = 5f(2)

f(3)=  5(25)

f(3)=  125

Now, n=4

f(4) = 5f(3)

f(4)=  5(125)

f(4)=  625

Now, n=5

f(5) = 5f(4)

f(5)=  5(625)

f(5)=  3125

Hence, the value of f(5) is 3125.
