$4867.2

Step-by-step explanation:

Answer:

Multiply 1/4 six times.

Start from zero and move 1/4 six times.

Product: 1 2/4      Other equivalent fractions: 2/3, 1 4/8, 18/12

Step-by-step explanation:

1.  1/4                      

2. 1/2 (2/4)

3. 3/4

4. one whole (4/4)

5. 5/4 ( 1 1/4)

6. 6/4 ( 1 2/4) (1 1/2)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1. 1/4 + 1/4 = 2/4

2. 2/4 + 1/4 = 3/4

3. 3/4 + 1/4 = 4/4

4. 4/4 + 1/4 = 5/4

5. 5/4 + 1/4 = 6/4

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1/4 times 6.                                      In other ways..  

6/4                                                                    1/4 times 6/1 = 6/4

Answer:

$32.65 is the answer.

Step-by-step explanation:

First, we must calculate 7.25% of 30.45.

30.45 x 0.0725 = $2.20

Now, we must add this to the original price

$30.45 + $2.20 = $32.65

Therefore, $32.65 is the total cost of his purchase.

Hope this helps! :)

Answer:

Step-by-step explanation:

before tax = $30.45

tax sales = 7.25%

total cost = $30.45 x 1.0725

               = $32.66

Answer:

Step-by-step explanation:

a). 3 ...... 8

3 × 8 = 24

3 + 8 = 11

b). n + 1.5 = 6.5 ⇒ n = 5 (across from OR to the left from 1.5)

5 × 1.5 = 7.5 (under the X sign)

Answer:

No she should add extra lengths

Step-by-step explanation:

The difference between scaled copy  and jada drawing is that it is in the ratio

8:4

2:1

that is the scaled copy is twice as large as the jada drawing itself.

So every dimension is doubled or made twice as large as the initial measurement. Andre should not add 4 units to all sides instead the drawing is made twice as large . It will serve the same purpose of enlarging the drawing while maintaining its shape. If extra mesurements are added the drawing will be changed.

Answer:

15

Step-by-step explanation:

3 counselors for every 20 girls

Answer:

15 counselors

Step-by-step explanation:

The ratio of counselors to girls is 6:40. Set this as a proportion:

[tex]\frac{6}{40}[/tex]=[tex]\frac{x}{100}[/tex]

Cross multiply to solve: 6×100=40x

600=40x

x=15

To satisfy the ratio, there needs to be 15 counselors for 100 girls.

Step-by-step explanation:

hey there,

< 3x-7x = -20-5

-4x = -25

x = [tex]\frac{25}{4}[/tex]

This isn't a square root or anything like that, so you would really only have 1 answer. I'm not sure what your teacher's referring to, though, but maybe they want decimals/mixed fractions?

But I would just put 1 if I were you. >

A, sorry if wrong but it can't be b or d

Answer:

5x + 10y = 125

Step-by-step explanation:

Let :

Number of nickel = x

Number of dime = y

Nickel = 5 cent

Dime = 10 cent

Total value = $1.25

Total value should be converted to cent since both dime and nickel are both in cent

= $1.25 * 100 = 125 cents

Therefore,

5x + 10y = 125 cents

Step-by-step explanation:

Shortest way to solve this question is to find the factors of the given expression.

The given expression is (x² + 13).

Now we have to factorize it.

(x² + 13) = x² + (√13)²

            = x² + [-(i)²√(13)²]  [Since i = √(-1)]

            = x² - (i√13)²

            = (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]-by-

Answer:

x = 15

Step-by-step explanation:

7x + 5x = 180 (because parallelograms are 360 degrees)

add like terms

12x = 180

divide 12 from both sides

[x = 15]

Answer:   9.75
