eimsori [14]2 years ago
7 0

Answer:

Let's call these numbers 4x and 6x, sum of 4x and 6x will be equal to 200, meaning  10x=200, If we divide both sides by 10, x will be equal to 20 and, the larger number 6x will be equal to, 6*20=120

Andrews [41]

Answer:

41cm

Step-by-step explanation:

The circumference of a circle is 82π

Therefore r can be calculated as follows

2 × π × r= 82× π

2πr= 82π

r = 82π/2π

r= 41

Hence r is 41cm

Write the statement for the problem in mathematical language. Use x for the tens digit and y for the unit digits in the two digi
Nutka1998 [239]

Answer:

  18

Step-by-step explanation:

A two-digit number (xy) will have the value 10x+y. The sum of its digits is x+y.

You want ...

  10x +y = 2(x +y)

  1 ≤ x ≤ 9

  0 ≤ y ≤ 9

The equation can be simplified to ...

  8x = y

The only single-digit values for x and y that satisfy the requirements are ...

  x = 1, y = 8

The two-digit number of interest is 18.

_____

<em>Check</em>

Its sum of digits is 1+8 = 9. 2×9 = 18.

_____

<em>Comment on the relationship in the problem</em>

Many of us learned our multiplication tables for 9s by remembering that the sum of digits of 9n was 9, and that the leading digit of the product was n-1.

A company made a profit of $90,000 in the year 2006. In 2010, the same company made a total profit of $135,000. If the rate of c
Firlakuza [10]

Answer:

Average rate of change = $11250 per year.

Step-by-step explanation:

Let's take two points from given information (2006, 90000) and (2010, 135000).

Now, use slope formula to find slope.

Slope =\frac{y2-y1}{x2-x1}

Use the two points to find average rate of change (slope)

Average rate of change =\frac{135000-90000}{2010-2006}

                                        =\frac{45000}{4}

                                       =11250

Average rate of change = $11250 per year.
