Answer:

910 boxes of toothpicks

Step-by-step explanation:

Create an equation to represent the situation, and let x represent the number of boxes of toothpicks.

1.20x - 0.1x = 1000

1.1x = 1000

x = 909.09

Round up to the nearest whole number:

= 910

So, Ronnie would have to sell 910 boxes of toothpicks to profit $1000.

Answer:

Rational

Step-by-step explanation:

An irrational number is a number that goes on forever, such as pi. These numbers have infinite decimals.

In contrast, a rational number is a number that can be created by dividing two other integers.

These numbers do not go on forever.

10 is a rational number because it can be created by dividing 2 other integers, and it does not go on forever.

Answer:

-4/3

Step-by-step explanation:

In y=mx+b, m represents the slope. In the second line, we are multiplying x by (3/4). This represents the slope of the second line.

To find the slope of a perpendicular line, we take the negative reciprocal of the current slope. In the first line, m represents the slope. The reciprocal of 3/4 is 4/3, and the negative reciprocal of 3/4 is -4/3. This is the value of m

Blank1=4   blank2=2\3

Step-by-step explanation:

2\3 for 1 recipe

For 7 recipe = 7 x 2\3

= 14\2 x 2\3 -> take out the 2

14\3 = 14 divided by 3 is 4 with remainder of 2

So, 4 2\3

Step-by-step explanation:

Answer:

The line drawn has a length of 6.4 cm.

Also it is divided into 4 equal parts.

Hence let the measure of the each equal part be ' x '

So x * 4 parts = 6.4 cm

=> x = 6.4 cm / 4

=> x = 1.6 cm

Hence the measure of each equal part is 1.6 cm.

Hence solved !

46 will be converted to .44m

x will be the mass of the 44 cm engine

x/72  =  .44^3/11^3

x/72 = 0.085/1331

cross multiply

1331x = 72 x 0.085

1331x = 6.12

x= 6.12/1331

=0.004598

x = 0.004598  tonnes

change to kilograms

0.004598*1000 = 4.6 kg

Answer:

  2/15 mi

Step-by-step explanation:

The difference of two fractions can always be computed using the pattern ...

  [tex]\dfrac{a}{b}-\dfrac{c}{d}=\dfrac{ad-bd}{bd}[/tex]

Using this pattern to find the difference of 1/3 and 1/5, we see it is ...

  1/3 -1/5 = (5 -3)/(3·5) = 2/15

Saji must swim 2/15 miles further to complete his 1/3 mile swim.

Answer:

$123,200

Step-by-step explanation:

0.06 x 2 = 0.12

140,000 x 0.12 = 16,800

140,000 - 16,800 = 123,200

The original buyer paid the amount of $123,200 for the property.

The percentage is defined as a ratio expressed as a fraction of 100.

The property appreciated by 6% per year, so in two years it would have appreciated by 6% × 2 years = 12%.

Once we know the total appreciation, we can subtract that value from 100% to find the original purchase price as a percentage of the final sale price.

If the property appreciated by 12%, then the original purchase price must have been 100% - 12% = 88% of the final sale price.

Now, multiply the final sale price by the original purchase price as a percentage to find the original purchase price.

So, the original buyer paid the amount = 88% × $140,000 = $123,200

Therefore, the original purchase price was $123,200.

Answer:

  C(x) = x/11 + 34 6/11

Step-by-step explanation:

The two given points are (x, C) = (60, 40) and (170, 50). These can be used in the 2-point form of the equation for a line to find the cost function.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (50 -40)/(170 -60)(x -60) +40

  y = (1/11)(x -60) +40

  C(x) = 1/11x +34 6/11 . . . . . . cost as a function of copies made

Answer:

D

Step-by-step explanation:

Remember that for this kind of question, when f(x) is given as 3, then 3 is the y value of the point. So you must have a point whose value is (x,3)

There is only one point that does that. x = - 2

The answer is D
