The speed limit in Canada is 100km/hr. What is the value of this limit in mi/hr given 1mi = 1.609km?
If the speed limit in Canada is 100km/hr than it's limit in mi/hr will be 62.15 mi/hr.
It is given in the question that 1.609 km = 1 mi
So , 1km= 1/1.609 mi
1km = 0.6215 mi
So if a car travels 1 km in 1 hr then it will travel 0.6215 miles in hr.
that means 1km/hr = 0.6215mi/hr
Now ,
to convert 100km/hr to mi/hr
we have ,

Find the irrational number to the nearest hundredth without using a calculator or number line.
Sorry it looks like that I hope someone understands 45
We know that the irrational number is between:
6 < √45 < 7
And a good estimation is √45 = 6.71
How to approximate the irrational number?Here we just need to find a lower and upper bound for the given irrational number.
To do it, we just need to find a square number larger and a square number smaller than the number inside the square root.
The larger one will be:
7*7 = 49
The smaller one will be:
6*6 = 36
Then we can write:
√36 < √45 < √49
6 < √45 < 7
So we now know that our number is between 6 and 7, that is already a good estimation, now you can also try to see if it is closer to 6 or 7, by taking the direct square root you will get:
Now just take the product between numbers of the form:
6.10*6.10 = 37.21
And so on, until we almost reach 45.
We will get:
6.71*6.71 = 45.02
So a good estimation is √45 = 6.71

Consider two neighboring island countries called Contente and Euphoria. They each have 4 million labor hours available per week that they can use to produce jeans, rye, or a combination of both. The following table shows the amount of jeans or rye that can be produced using 1 hour of labor.
Country Jeans Rye
Contente 5 10
Euphoria 4 16
Initially, suppose Contente uses 1 million hours of labor per week to produce jeans and 3 million hours per week to produce rye, while Euphoria uses 3 million hours of labor per week to produce jeans and 1 million hours per week to produce rye. Consequently, Contente produces 5 million pairs of jeans and 30 million bushels of rye, and Euphoria produces 12 million pairs of jeans and 16 million bushels of rye. Assume there are no other countries willing to trade goods, so, in the absence of trade between these two countries, each country consumes the amount of jeans and rye it produces.
Contente's opportunity cost of producing 1 pair of jeans is ___ of rye, and Euphoria's opportunity cost of producing 1 pair of jeans is ___ of rye. Therefore ___ has a comparative advantage in the production of jeans, and ___ has a comparative advantage in the production of rye.
Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. In this case, the country that produces jeans will produce ___ million pairs per week, and the country that produces rye will produce ___ million bushels per week.
n the following table, enter each country's production decision on the third row of the table (marked “Production”).
Suppose the country that produces jeans trades 13 million pairs of jeans to the other country in exchange for 39 million bushels of rye.
In the following table, select the amount of each good that each country exports and imports in the boxes across the row marked “Trade Action,” and enter each country's final consumption of each good on the line marked “Consumption.”
When the two countries did not specialize, the total production of jeans was 17 million pairs per week, and the total production of rye was 46 million bushels per week. Because of specialization, the total production of jeans has increased by ___ million pairs per week, and the total production of rye has increased by ___ million bushels per week.
1. Euphoria's opportunity cost of producing a a bushel of rye is 4 pairs of jeans.
Contentes opportunity cost of producing a bushel of rye is 2 pairs of jeans.
2. Contente has comparative advantage in producing rye
Euphoria has comparative advantage in jeans production
How to find the opportunity Cost?For Euphoria:
The opportunity cost of producing a unit of rye in terms of jeans is;
Opportunity Cost = 20/5 = 4
For contente:
The opportunity cost of producing a unit of rye in terms of jeans is;
Opportunity Cost = 16/8 = 2
The opportunity cost of producing 1 unit of jean in terms of unit of rye:
For euphoria = 5/20 = 1/4
For contente = 8/16 = 1/2
1. Euphoria's opportunity cost of producing a a bushel of rye is 4 pairs of jeans.
Contentes opportunity cost of producing a bushel of rye is 2 pairs of jeans.
2. Contente has comparative advantage in producing rye
Euphoria has comparative advantage in jeans production
3. Contente produces 8 bushels of rye so with 4 million hours of labor = 8x4 = 32 million bushels in a week.
Euphoria 20 pairs of jean in a week, using 4 million hours of labor. 20x4 = 80 pairs of jean a week

Tacoma's population in 2000 was about 200 thousand, and has been growing by about 9% each year. If this continues, what will Tacoma's population be in 2017?
_____ thousand people
The population of Tacoma in 2017 would be 865,527.
What will be the population in 2017?If the population grows by 9% every year, the population would grow at a compound rate each year and the equation that can be used to determine the population in 2017 would be an exponential equation.
Compound growth is when both the existing population and the increase in population every year.
The equation that can be used to determine the population of Tacoma in 2017 is:
The formula for calculating future value:
FV = P (1 + r)^n
Where:
FV = Future value P = Present populationR = rate of growthN = number of years : 2017 - 2000 = 17200,000 x (1 + 0.09)^17
200,000 x (1.09^17) = 865,526.68
In order to round 865,526.68 to the nearest whole number , look at the tenth figure, if it is greater or equal to 5, add one to the units digit and change the tenth and hundredth digit to 0. So, 865,526.68 becomes 865,527.

60units needed 14 units per case what's the #of cases & # of additional units
There will be 5 cases and 10 additional units.
Here, we are given that 60 units are needed with 14 units per case.
The total number of units required = 60
Units required for 1 case = 14
Let the total number of cases = n
Thus, total number of units required for n cases = 14n
⇒ 60 = 14n
14n = 60
n = 60/ 14
n = 4.285
Thus, we get that the number of cases = 4.285
But, since cases cannot be in decimals, we need to round off n to 5 ( as 4 cases won't add up to 60).
Thus, the total number of cases are 5.
Additional units = 14 × 5 - 60
= 70 - 60
= 10

r squared minus 15 = t + 19
The given equation r² - 15 = t + 19 is the equation of a parabola with vertex at (h, k) = (0, -34) and focal length |p| = 1/4.
I assume that the question is to describe or graph the equation r² - 15 = t + 19.
The given equation r² - 15 = t + 19 is the equation of a parabola with vertex at (h, k) = (0, -34) and focal length |p| = 1/4.
4p(y - k) = (x - h)² is the common equation for a parabola that faces up and down and has a vertex at (h, k) and a focal length of |p|.
Let us re-write the given equation in the standard form.
r² - 15 = t + 19
⇒ r² = t + 19 + 15
⇒ r² = t + 34
⇒ (r - 0)² = t + 34 (r can be written as r - 0)
⇒ (r - 0)² = t - (-34) (+34 is written as -(-34))
⇒ (r - 0)² = 4 × 1/4 × (t - (-34))
(4 × 1/4 is equal to 1. The given equation is unaffected by a multiplication by 1.)
⇒ 4 × 1/4 × (t - (-34)) = (r - 0)² this equation is in the standard form. And here we have |p| = 1/4 and (h, k) = (0, -34).

The formula for geometric progression can be presented as follows;
[tex] a_{n} = a_{1} \times {r}^{n - 1} [/tex]
[tex]a_{4} =108 = a_{1} \times {r}^{4 - 1} [/tex]
Where;
[tex]a_{1} = 4 \: and \: a_{4} = 108[/tex]

Which gives;
[tex] {r}^{3} = \frac{108}{4} = 27[/tex]
[tex]r = \sqrt[3]{27} = 3[/tex]
r = 3
Therefore;

Second part;
Where;
[tex]a_{1} = 9 \: and \: a_{3} = 144[/tex]
