the average rate of change is the same as
the slope of a line m = (y2-y1)/(x2-x1)
to find if is positive of negative look at the line between the years given (for example between 1930 and 1940)
if from left to right the line goes downward the rate of change is negative
if from left to right the line goes upward the rate of change is positive

1. 258 square meters
2. 180 square meters
3. 286 square feet
Step-by-step explanation:
1. Find the surface area of each side:
9 * 5 + 5 * 6 + 9 * 5 + 6 * 5 + 9 * 6 + 9 * 6
45 + 30 + 45 + 30 + 54 + 54
75 + 75 + 108
150 + 108
258
2. Base: 5 * 5 = 25
Top: 5 * 5 = 25
Sides: each 5 * 6.5 = 32.5
Altogether: 32.5 * 4 = 130
130 + 25 + 25 = 180
3. Base and top: both 8 * 10 = 80, together 80 * 2 = 160
Front and back sides: both 8 * 3.5 = 28, together 28 * 2 = 56
Left and right sides: both 10 * 3.5 = 35, together 35 * 2 = 70
Altogether: 160 + 56 + 70 = 286 sq feet
In the diagram, △RST∼△R′S′T′. Determine the length of RS. Show your work.
100 points!
Answers
Explanation: Since the triangles are similar, we can use the proportion 9/4=(12x+2)/(5x+1).
Cross multiplying 9*(5x+1) and 4*(12x+2) gives us 45x+9=48x+8.
Solving for x gives us 1/3.
You can check your work by plugging in x for the two equations, which gives us 6 (RS) and 8/3 (R’S’)
The scale factor is 4/9 (k) from 9k=4
6*4/9=8/3 and (8/3)/(4/9)=6
Answer:
RS = 6 feetStep-by-step explanation:
Use ratios of corresponding sides:
TS/T'S' = RS/R'S'Substitute and solve for x:
9/4 = (12x + 2)/(5x + 1)9(5x + 1) = 4(12x + 2)45x + 9 = 48x + 848x - 45x = 9 - 83x = 1x = 1/3Find the length of RS:
RS = 12x + 2 = 12(1/3) + 2 = 4 + 2 = 6 feetIf 35% of a number is 98 and 80% of the same number is 224, find 45% of that number.
Answers
9514 1404 393
Answer:
126
Step-by-step explanation:
If n represents the original number, we have
(35%)n = 98
(80%)n = 224
We want to find (45%)n.
(45%)n = (80% -35%)n = (80%)n -(35%)n
(45%)n = 224 -98 = 126
45% of the number is 126.

I WILL AWARD DA BRILLIANT AWORD THINGY
Answers
Answer:
Yes
Step-by-step explanation:
A transversal line is a line that intersects two or more lines. Since line C is intersecting two lines, it is transversal.
The required line C is a transversal of lines a and b.
What is a line?A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.
Here,
The line which intersects two or more lines is said to be a transversal line.
So as of the given figure, line C intersects line a and line b so Line C is a transversal line.
Thus, the required line C is a transversal of lines a and b.

An aquarium contained an equal number of horseshoe crabs and sea stars. After 15 horseshoe crabs were removed and 27 sea stars were removed, the ratio of horseshoe crabs to sea stars was 5:3. How many horseshoe crabs and sea stars were there at first? Solve this problem and explain your reasoning.
Answers
Answer:
45 horseshoe crabs and 45 sea stars
Step-by-step explanation:
The aquarium initially contained x crabs and x sea stars.
"After 15 horseshoe crabs and 27 sea stars are removed the ratio of horseshoe crabs to sea stars is 5:3"
(x-15):(x-27) = 5:3
(x-15)/(x-27) = 5/3
3(x-15) = 5(x-27)
3x-45 = 5x-135
90 = 2x
x = 45

13. A certain town with a population of 100,000 has 3 newspapers: I, II, and III. The proportions of townspeople who read these papers are as follows: I: 10 percent I and II: 8 percent I and II and III: 1 percent II: 30 percent I and III: 2 percent III: 5 percent II and III: 4 percent (The list tells us, for instance, that 8000 people read newspapers I and II.) Find the number of people who read only one newspaper. How many people read at least two newspapers
Answers
Answer:
a) the number of people who read only one newspaper is 20,000
b) number of people read at least two newspapers is 12,000
Step-by-step explanation:
Given the data in the question;
A certain town with a population of 100,000 has 3 newspapers
a)Find the number of people who read only one newspaper
From the Venn-diagram illustrating the data in the question;
Number of that read only one paper will be;
=[ ([tex]I^{}[/tex]∩ [tex]II^{c}[/tex] ∩ [tex]III^{c}[/tex]) + ( [tex]I^{c}[/tex] ∩ [tex]II^{c}[/tex] ∩ [tex]III^{c}[/tex]) + ( [tex]I^{c}[/tex] ∩ [tex]II^{c}[/tex] ∩ [tex]III^{}[/tex]) ] × 100,000
= [ 1% + 19% + 0% ] × 100,00
= 20% × 100,000
= 20,000
Therefore, the number of people who read only one newspaper is 20,000
b) How many people read at least two newspapers;
Number of people read at least two newspapers will be;
= [ ([tex]I^{}[/tex]∩ [tex]II^{}[/tex] ∩ [tex]III^{c}[/tex]) + ( [tex]I^{}[/tex] ∩ [tex]II^{c}[/tex] ∩ [tex]III^{}[/tex]) + ( [tex]I^{c}[/tex] ∩ [tex]II^{}[/tex] ∩ [tex]III^{}[/tex]) + ( [tex]I^{}[/tex] ∩ [tex]II^{}[/tex] ∩ [tex]III^{}[/tex]) ] × 100,000
= ( 7% + 1 % + 3% + 1% ) 100,000
= 12% × 100,000
= 12,000
Therefore, number of people read at least two newspapers is 12,000
A 5-pound bag of red onions costs $3.90. What is the unit price?
per pound
Answers
I hoped that this helped
Answer:
OK, I love these questions. The way to get the answer is always remember this formula- (PRICE DIVIDED BY QUANTITY). In this case, the price for a 5 pound bag of onions costs 3.99. So, to find the unit price per pound, all you need to do is divide 3.99 by 5. If you do the math (3.99/5), you'll get the answer of 79 cents per pound. If your asked to round, the answer would be 80 cents per pound.
