Distance Conversions The United States, Liberia, and Myanmar are the only three countries that have not adopted the metric system as its primary system of measurement. There have been reports and legislation calling for a conversion to the metric system since the 1960s. The U.S. Department of Commerce's National Institute of Standards and Technology wrote that "industrial and commercial productivity, mathematics and science education, and the competitiveness of American products and services in world markets, will be enhanced by completing the change to the metric system of units" (1997, 2). From a student's perspective, it would be better if the U.S. converted to the metric system. Because scientists globally use the metric system, most of U.S. scientists do, as well. Until the U.S. "metrifies", students in the United States will need to continue to use and understand both measurement systems. 6. Refer to Appendix 2.1.

b. 63360 in.
c. 10000 m
d. 100000 cm
e. 3.107 miles
f. 42.165 km
Step-by-step explanation:
a. 2 miles contain how many feet?
1 mile = 5280 ft
2 miles × 5280 ft / mile = 10560 ft
b. 1 mile contains how many inches?
1 ft = 12 in
1 mile × 5280 ft/mile × 12 in./ft = 63360 in.
c. 10 kilometers contain how many meters?
1 km = 1000 m
10 km × 1000 m/km = 10000 m
d. 1 kilometer contains how many centimeters?
1 km × 1000 m/km × 100 cm/m = 100000 cm
e. How many miles are in a "5k" (five-kilometer) race?
1 in. = 2.54 cm
5 km =
= 5 km × 1000 m/km × 100 cm/m × 1 in. / (2.54 cm) × 1 ft / (12 in.) × 1 mile / (5280 ft)
= 3.107 miles
f. A marathon is 26.2 miles. How many kilometers is this?

5.find the surface area of a rectangular prism with a length of 5cm width of 8cm and a height of 6cm
6.what is the surface area of a square pyramid with a side of 9cm and a height of 7cm.
Answers
Surface area = π(5m)² + π(5m)(8m)
Surface area = π(25m²) + π(40m²)
Surface area = 25πm² + 40πm²
Surface area ≈ 188.5m²
Therefore, the surface area of the cone is approximately 188.5 square meters.
2. The surface area of a cube can be found using the formula: 6s², where s is the length of one side of the cube. Plugging in the value given, we get:
Surface area = 6(9cm)²
Surface area = 6(81cm²)
Surface area = 486cm²
Therefore, the surface area of the cube is 486 square centimeters.
3. The surface area of a cube can be found using the formula: 6s², where s is the length of one side of the cube. Plugging in the value given, we get:
Surface area = 6(8cm)²
Surface area = 6(64cm²)
Surface area = 384cm²
Therefore, the surface area of the cube is 384 square centimeters.
4. The surface area of a rectangular prism can be found using the formula: 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the prism. Plugging in the values given, we get:
Surface area = 2(6m)(10m) + 2(6m)(7m) + 2(10m)(7m)
Surface area = 120m² + 84m² + 140m²
Surface area = 344m²
Therefore, the surface area of the aquarium is 344 square meters.
in a group of 900 students, 612 like football and
540 like volleyball. If all the students like at least one
game, find the following by using Venn diagramHow
many students like both game ?
How many students like only football?
Answers
Answer: Let's use a Venn diagram to solve this problem.
First, we know that 612 students like football, 540 students like volleyball, and all students like at least one game. This means that there is some overlap between the two groups in the Venn diagram.
Let x be the number of students who like both games. Then, the number of students who like only football is 612 - x, and the number of students who like only volleyball is 540 - x.
Since all 900 students like at least one game, we can add up the number of students in each of these three groups and set the sum equal to 900:
(612 - x) + x + (540 - x) = 900
Simplifying the left side of the equation gives:
1152 - 2x = 900
Subtracting 1152 from both sides gives:
-2x = -252
Dividing both sides by -2 gives:
x = 126
Therefore, 126 students like both football and volleyball.
To find the number of students who like only football, we can substitute x = 126 into the expression 612 - x:
612 - 126 = 486
Therefore, 486 students like only football.

Answers
The number of men on the sight - seeing tour was 22 .
In the question ,
it is given that,
the ratio of women to children on the tour is = 5 : 2
let the number of men in the sight seeing tour = m
let the number of women in the sight seeing tour = w
let the number of children in the sight seeing tour = c
So , w/c = 5x/2x
also the ratio of children to men is 5/11 ,
c = 5y and m = 11y
the number of women on the sight seeing tour is less than 30 ,
which is 5x < 30 ,
x < 6
but we have c = 2x and 5y ,
and since c is a multiple of 5 , 2x also has to be a multiple of 5 ,
earlier we got , x < 6 ,
Now using x =5 , we get c = 2*5 = 10
and so , 10 = 5y
y = 2 ,
So , the number of men = 11y = 11*2 = 22 men
Therefore , the number of men are 22 .
The given question is incomplete , the complete question is
On a certain sight-seeing tour, the ratio of the number of women to the number of children was 5 to 2. What was the number of men on the sight-seeing tour?

At the stadium, there are seven lines for arriving customers, each staffed by a single worker. The arrival rate for customers is 180 per minute and each customer takes (on average) 21 seconds for a worker to process The coefficient of variation for arrival time is 13 and the coetficient of variation forservice time 13. (Round your anwwer to thees decimal paces) On average, tiow many customers wis be waits in the queve? customers
Answers
On average, approximately 3.152 customers will be waiting in the queue at the stadium.
To calculate the average number of customers waiting in the queue, we can use the queuing theory formulas. The arrival rate of customers is given as 180 per minute, which means the arrival rate is λ = 180/60 = 3 customers per second. The service time is given as an average of 21 seconds per customer, so the service rate is μ = 1/21 customers per second.
To calculate the utilization factor (ρ), we divide the arrival rate by the service rate: ρ = λ/μ. In this case, ρ = 3/1/21 = 9.857.
Next, we calculate the coefficient of variation for arrival time (C_a) and service time (C_s) using the given values. C_a = 13% = 0.13 and C_s = 13% = 0.13.
Using the queuing theory formula for the average number of customers waiting in the queue (L_q), we have L_q = ρ^2 / (1 - ρ) * \((C_{a}^2 + C_{s}^2)\) / 2.
Plugging in the values, L_q = \((9.857^2) / (1 - 9.857) * (0.13^2 + 0.13^2) / 2 = 3.152\).
Therefore, on average, approximately 3.152 customers will be waiting in the queue at the stadium.

IF U ANSWER THIS I MA GIVE U 45 POINTS AND PLUS IM GOING TO GIVE U A BRAINLIES From Get Engaged! Part 1, if you thought that the monthly payment is the most important factor for Juan to consider, then you are correct. He should still consider the amount of interest that he will be paying, but if he can only pay a certain amount each month, he is not able to pick a payment plan based only on interest.
How can Juan compare the amount of interest of the two plans he has been presented with? Juan will need to multiply … _______________________________.
Great work! In order to find out how much Juan will pay in interst for each plan (3 years versus 5 years), we have to start by finding out how many months are in 3 years and 5 years. Since there are 12 months in one year, you can multiply 12 x 3 and 12 x 5.
PLAN 1: In the first plan, Juan pays $456 for 36 months. 456 x 36 = $16,416. The cost of the car is $15,000. In order to find the interest, we have to find the difference between the total amount that Juan would pay and the cost of the car: 16,416 - 15,000 = $1,416 in interest.
PLAN 2: In the second plan, Juan pays $289 for 60 months. 289 x 60 = $17,340. The cost of the car is $15,000. In order to find the interest, we have to find the difference between the total amount that Juan would pay and the cost of the car: 17,340 - 15,000 = $2,340 in interest.
