Step-by-step explanation:
Given
US Population in 2014: About 318,900,000
Required
Approximate
From the given options, it's seen that the population of US is to be approximated to one significant digit and the result should be presented in standard form
So, the first step is to write out the population
318,900,000
As a general rule,
Category 1: Digit 0-4 are approximated to 0
Category 2: Digit 5-9 are approximated to 1
Since, we are approximating to one significant digit, only the first digit is needed, others are to be approximated.
The first digit is 3, meaning that approximation starts from the next digit which is 1
Approximating 318,900,000 will give 300,000,000 because "1" falls in category 1 as illustrated above.
The final step is to convert 300,000,000 to standard form.
There are 8 0s after 3.
Hence,
Conclusively, the approximation of 318,900,000 is people

7. A frying pan can hold 2 dozen wantons at a time.
It takes 5 minutes to fry 2 dozen wantons. How
long will it take to fry 40 dozens wantons
Answers
Answer:
100 minutes
Step-by-step explanation:
This is because it takes 5 minutes to fry 24 wantons, so we can write 5/24. Now we need to find out how long it takes to fry 40 dozen wantons, or 480 wantons. We can rewrite this as x/480. Since the time should be proportional, we get the following:
5/24 = x/480
We can now cross multiply. 24x=5x480. Therefore, 24x = 2400. If we divided each side by 24, we would get 100. Therefore, it takes 100 minutes to fry 40 dozen wantons, or about 1 2/3 hours.
Answer:
100 minutes (1 hour & 40 minutes).
Step-by-step explanation:
5 minutes = 2 dozen, which means it takes 2.5 minutes to cook 1 dozen.
2.5 minutes x 40 dozen = 100 minutes...

Answer:
area = 1539√3 in²
Step-by-step explanation:
three hexagons and one triangle:
each of the three hexagons are composed of 6 equilateral triangles just like the center triangle.
So you have 19 equilateral triangles with each side being 18 inches long.
The height (h) of a triangle will be:
h² = 18² - 9² = 324 - 81 = 243
h = √243
h = 9√3
area of one triangle = 1/2bh = (1/2)(18)(9√3) = 81√3
81√3(19 triangles) = 1539√3 in²

What is Arithmetic Mean?The simplest method to determine the average for the given collection of integers is to use the arithmetic mean or mean. It is divided into two categories: weighted arithmetic mean and plain arithmetic mean.
The ratio of the total number of observations divided by the sum of all the given observations is known as the arithmetic mean.
We have,
Corey scored 85, 89, 87, 92, and 98 on his math tests.

What is the end behavior of the function f(x)=2/3x^3?

Answers
Answer:
As x→[infinity], f(x)→[infinity] As x→−[infinity], f(x)→−[infinity]
Step-by-step explanation:
Since f(x) =2x³/3,
Let x → + ∞
Substituting x = + ∞ into the equation, we have
f(+∞) = 2(+∞)³/3
= + 2∞³/3
= + ∞ (since + 2∞³/3 → +∞ (a larger number))
So as x → + ∞, f(x) → + ∞
Let x → - ∞
Substituting x = - ∞ into the equation, we have
f(-∞) = 2(-∞)³/3
= - 2∞³/3
= - ∞ (since - 2∞³/3 → -∞ (a larger number))
So as x → -∞, f(x) → -∞
So, the answer is As x→[infinity], f(x)→[infinity] As x→−[infinity], f(x)→−[infinity]
Kim has 12 ounces of water. She pours some waer into a bottle that holds exactly 1 cup. How many ounces of water are left over after him fills the bottle.
Answers
Answer:
4 ounces
Step-by-step explanation:
the measurement of water and the bottle are in different units. This, they have to be converted to the same units
1 cup = 8 ounces
if the bottle holds one cup, it would hold 8 ounces
ounces of water left over = 12 - 8 = 4 ounces

If the value of y varies inversely with x , which function represents the relationship between x and y if y = 48 when x = 3?
A. Y= 144/x
B. Y= 16/x
C. Y= x/16
D. Y= x/144
Answers
Answer:
A. Y = 144/x
Step-by-step explanation:
Inversely means y = 1/x
If y = 48, when x = 3
so 144/3 = 48
Therefore the answer is A
If the value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3
What is a function?A relation is a function if it has only One y-value for each x-value.
If y varies inversely with x, it means that y is inversely proportional to x, or y=k/x, where k is a constant of proportionality.
To find k, we can use the given values of y and x:
y = k/x
48 = k/3
k = 144
Now that we know k, we can write the function that represents the relationship between x and y:
y = 144/x
Therefore, if the value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3

What we have here are right triangles
For right triangles, the square of the hypotenuse (the side facing the right angle) equals the sum of the squares of the two other sides
Starting from the left;
a) 13^2 = 12^2 + 5^2
169 = 144 + 25
169 = 169
This triangle is valid
b) 25^2 = 24^2 + 7^2
625 = 576 + 49
625 = 625
This triangle is valid
c) 5^2 = 3^2 + 2^2
25 = 9 + 16
25 = 25
