Answer:
55
Step-by-step explanation:
You would do 5 x 11 and that gives you 55 :)
Answer:
- <em>The</em> <u>constant</u> <em>of proportionality is the</em> <u>value</u> <em>of the ratio of the two proportional quantities.</em>
Explanation:
Two quantities are proportional or have a direct proportional relationship if their quotient, also called ratio, is constant.
In such a case you can write:
- Amount of x / amount of y = constant, or simply:
Where the notation x / y is the ratio and k is the constant of proportionality.
From that expresssion, it is proved that when two quantities are proportional, if one doubles the other also doubles, if one quadruples the other also quadruples, and in general, if one is multiplied by a factor the other is multiplied by the same factor;
For example, the number of pencils and the number of boxes of pencils are proportional because:
- 120 pencils / 10 boxes 12
The constant of proportionality is 12, indicating that each box contains 12 pencils; thus, both quantities (number of pencils and number of boxes of pencils) have a constant ratio of 12.
Answer:
yes
Step-by-step explanation:
We can estimate* that the total price including tax of the game will be less than ...
$43.31 +10% of 43.31 = $43.31 +4.33 = $47.61
Todd easily has enough to pay for the game, including tax.
_____
You can work this more exactly a couple of ways.
1. Price + tax = 1.085×$43.31 = $46.99 . . . less than Todd's budget
2. Most Todd can afford: $55.50/1.085 = $51.15 . . . more than the game price
_____
* For estimating purposes, we like to use numbers that are easy to compute with. 10% is one such number, as it only requires moving the decimal point.
Answer:
60 and 40 or 120 and 20
Step-by-step explanation:
60 x 2=120
40 x 3=120
60 x 40=2400
120 x 1=120
20 x 6=120
120 x 20=2400
You can try a few others, but no others have an lcm of 120
