Explanation:
The jump from 30 miles to 150 miles is "times 5", meaning 30*5 = 150.
So we need to multiply both sides of the equation
30 miles = 1 cm
by 5 and we get
5*(30 miles) = 5*(1 cm)
150 miles = 5 cm
--------------------
Another way to solve:
This involves proportions
Let x be the distance on the paper map that corresponds to 150 miles
(150 miles)/(x cm) = (30 miles)/(1 cm)
150/x = 30/1
150*1 = x*30 .... cross multiply
150 = 30x
30x = 150
30x/30 = 150/30 ... divide both sides by 30
x = 5 cm is the distance on the paper map

Suppose a special interest group in a state is promoting an amendment to the state constitution so that residents can legally consume marijuana for medical and recreational use. They declare that voters in the state are strongly in support of the legalization of marijuana. This declaration is based on data collected in a sample survey. The group used the white pages of telephone directories of the three largest metropolitan areas in the state and randomly selected residential phone numbers to call in each city. They made calls until they had 500 responses per area. The relevant population of interest is:
Answer:
All Registered voters in the state
Step-by-step explanation:
The random sample utilized involves a random subset of citizens from each of the 3 largest cities in the state. The larger group which consists of all set of observation from which the smaller sample used in the survey was chosen is called the population.
Hence, the relevant population may be said to encompass all citizens of the state who have attained voting age and are registered, hence, all citizens in the state who are registered voters.

Please give me an answer with an explanation.
Answer:
40 and 10
Step-by-step explanation:
1. if the length is 'l' and height is 'h', then according to the condition 1/4*l=h.
2. if the given area is 400, it means, h*l=400;
3. if to substitute h=1/4*l into the formula of the area, then
l*l*1/4=400; ⇔ 1/4*l²=400;
4. if to calculate the value of the 'l', then l=40 (the required length).
5. if to substitute l=40 into 1/4*l=h, then h=10 (the required height).

Function p gives the perimeter of an equilateral triangle of side length s. It is represented by the equation p(s)=3x
a. What does P(s)=60 mean in this situation?
b. Find a value of s to make the equation P(s) = 60 true.
Answer:
A) p(s) means that the perimeter of the triangle is 60 units.
B) A value to make the equation true is s = 20
Step-by-step explanation:
In the equation p(s) = 60, 60 represents the perimeter of the equilateral triangle.
To find a value of s that makes the equation p(s) = 60 true, plug in 60 as p(s) and solve for s.
p(s) = 3s
60 = 3s
20 = s
So, s = 20 will make the equation true

Answer the questions to find the measures of ∠2 and ∠3.
1. What is the measure of ∠4? Explain how you know.
Write your answer in the space below.
2. What is the sum of the measures of the angles in a triangle?
Write your answer in the space below.
3. ∠1 is in a triangle with ∠4 and a 53° angle. What is the sum of the measures of those two angles?
Write your answer in the space below.
4. What is the measure of ∠1? Explain.
Write your answer in the space below.
5. Find the measure of ∠2. Explain how you found its measure.
Write your answer in the space below.
6. What is the measure of ∠3? Explain.
Write your answer in the space below.
For question 1 and 2, you should keep in mind that the sum of all angles in a triangle is 180°. 1. If the measure of one angle of a triangle is 90 degrees, you can assume that the sum of the other two triangles should be 90 degrees. Because
180 - 90 = 90
The sum of the three angles of any triangle is equal to 180 degrees.
Angle 2=127 because 180-53=127.
Angle 3=23 because 180-30-127=53
Angle 1=37 because 90-53=37
Angle 4=90
Angle 1+4=127
The measure of ∠1 is 125° .
Next x+64=110. The reason why you can do this is because ∠R is going to be an opposite interior angle. Subtract 64 from the left and right sides. x=46

What is the slope of a line that is perpendicular to the line y = 1/6x + 4
The slope of the line is
Answer:
-1/6x
Step-by-step explanation:
for a slope to be perpindicular it has to be the opposite.
Hello there! :)
Perpendicular lines have slopes that are opposite reciprocals. It means that if we have a number, we flop it over and make it negative.
We have 1/6.
We flop it over:
6/1
Now, we make it negative:
-6/1
-6/1 simplifies to
-6

A new energy drink advertises 130 calories for 6 oz. How many calories are in 18oz of the drink?
Answer:
390 calories
Step-by-step explanation;
18/3=6
130 x 3 = 390
Answer:
390
Step-by-step explanation:
You can set up a simple ratio, 130 is to 6 as x is to 18. Notice how 6x3=18 so since you multiplied the 6 by 3, then multiply the 130 by 3, so 130 x 3 = 390 calories

What single decimal multiplier would you use to decrease by 1% followed by a 4% increase?
Answer:
The single decimal multiplier is 1.0296.
Step-by-step explanation:
Multipliers:
For a decrease of a%, we multiply by: [tex]\frac{100-a}{100}[/tex]
For a increase of a%, we multiply by: [tex]\frac{100+a}{100}[/tex]
For consecutive changes, we multiply the multipliers.
Decrease of 1%
Multiplication by [tex]\frac{100-1}{100} = \frac{99}{100} = 0.99[/tex]
Increase of 4%
Multiplication by [tex]\frac{100+4}{100} = \frac{104}{100} = 1.04[/tex]
Consecutive:
0.99*1.04 = 1.0296
The single decimal multiplier is 1.0296.
