here are the approximate population of three countries, expressed in scientific notation: panama: 4 x 10^6 ; peru: 3.2 x 10^7 ; thailand: 7 x 10^7. Lin says that more than 20 times as many people live in thailand than in panama. Is this correct​

Answers

Answer 1

Answer:

No, Lin assumption is wrong

Step-by-step explanation:

Given

Population of panama = 4 x 10^6

population of thailand = 7 x 10^7.

Taking their ratios

thailand/panama = 7x 10^7/4 x 10^6

thailand/panama  = 7/4 * 10^7-6}

thailand/panama = 1.75 * 10^1

thailand/panama  = 17.5

thailand = 17.5 * panama

Hence the amount of people in thailand is not up to 20times those in panama. Hence Lin assumption is wrong

Answer 2

Using proportions, it is found that the ratio is of 17.5, hence Lin is not correct.

What is a proportion?

A proportion is a fraction of a total amount.

In this problem:

Thailand's population is of 7 x 10^7.Panama's population is of 4 x 10^6.

The ratio between the populations is given by:

r = 7 x 10^7/(4 x 10^6) = 1.75 x 10^1 = 17.5.

The ratio is of 17.5, hence Lin is not correct.

Unit 10: Circles Homework 4: Inscribed Angles

Find each angle or arc measure of mRS

Answers

Answer:

96 degrees

Step-by-step explanation:

Since you know that arc are twice the angle measure, that means arc RT is 42 * 2 = 84. Then, you have to find the measure of RS.

Remember that arc RT and RS have to add up to 180 degrees because they form a semicircle (half of a circle).

To find the measure of RS, just do 180 - 84 = 96 degrees.

Answers

Answer:

(5a−3)^2

Step-by-step explanation:

25a^2 - 30a + 9

Factor the expression by grouping. First, the expression needs to be rewritten as 25a^2+pa+qa+9. To find p and q, set up a system to be solved.

p+q=−30

pq=25×9=225

Since pq is positive, p and q have the same sign. Since p+q is negative, p and q are both negative. List all such integer pairs that give product 225.

−1,−225

−3,−75

−5,−45

−9,−25

−15,−15

Calculate the sum for each pair.

−1−225=−226

−3−75=−78

−5−45=−50

−9−25=−34

−15−15=−30

The solution is the pair that gives sum −30.

p=−15

q=−15

Rewrite 25a^2 - 30a + 9 as (25a^2−15a)+(−15a+9).

(25a^2−15a)+(−15a+9)

Factor out 5a in the first and −3 in the second group.

5a(5a−3)−3(5a−3)

Factor out common term 5a−3 by using distributive property.

(5a−3)(5a−3)

f(x) = -Lxl is the function and -3 ≤x≤3 is the domain that could represent the given graph .

What is a function ?

Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

here, we have,

We know, domain is:

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

Thus , from the graph it can be clearly depicted that it is representing f(x)=-Lxl for an entire range of  -3 ≤x≤3 .

Hence , f(x) = -Lxl is the function and -3 ≤x≤3 is the domain that could represent the given graph .
