Step-by-step explanation:
To find Hypotenuse: Pythagorean Theroem
a^2+ b^2= c^2
The legs are A and B
The side that is directly across from the Right angle is C
12^2 + 16^2 =C^2
144+256=400
400 = c^2
Square root on both sides to get rid of c^2
The square root of 400 is 20
c=20
Answer:
20 feet
Step-by-step explanation:
c = (a² + b²)
c= (12^2 + 16^2)
c= square root (400)
c= 20

There are 3 red balls, 5 green balls, and 1 yellow ball in a hat. If you draw the yellow ball, you gain $10. If you draw any of the red balls, you gain $4. If you draw a green ball, you lose $3. If you were to play this game 25 times, replacing the drawn ball each time, how much money can you expect to gain or lose?
Answers
Answer:
19.44
Step-by-step explanation:
We have the following information:
3 red balls, 5 green balls, and 1 yellow ball
In total there are 3 + 5 + 1 = 9 balls.
We calculate the probability of each:
Network: 3/9
Green: 5/9
Yellow: 1/9
Each one corresponds a price in profit or losses:
Network: 4
Green: -3
Yellow: 10
So in total it would be the sum of the multiplication of the probability and the price and then multiply everything by 25:
(4 * 3/9 + -3 * 5/9 + 10 * 1/9) * 25 = (0.777) * 25
= 19.44

What is the value of x in the figure? Enter your answer in the box.
Answers
Answer:
x = 65
Step-by-step explanation:
2x + 15 and 145 are vertical angles and congruent, thus
2x + 15 = 145 ( subtract 15 from both sides )
2x = 130 ( divide both sides by 2 )
x = 65
Answer:65
Step-by-step explanation:
2x+15=145. Because opposite angles are equal
2x+15=145
Collect like terms
2x=145-15
2x=130
Divide both sides by 2
2x/2=130/2
x=65

y=6x
y=42
simplify the answer as much as possible
Answers
Explanation: because 6x7=42 and 42 is y
1. Set both of the equations equal to each other to find x.
2. 6x=42
3. Divide both sides by 6.
4. X=7
5. Now let’s find y
6. y=42
7. Check your work:
Plug in the value of x into this equation. y=6x
We know that x=7, so y=6(7)= 42
This means that x=7 and y=42

What are the zeros of the function shown in the graph?
Answers
Answer: x = 2, -4
Step-by-step explanation:
The zeros of a function are where the function crosses the x-axis, in this case, the function crosses the x-axis at 2 and -4, so 2 and -4 are the zeros of this function.
Hope this helps.
Answer:
By definition, the zeros of a function f(x) are all the values x for which f(x) = 0. In other words, the zeros of a function f(x) are the intersections of the graph of f(x) with the axis of x. Therefore, to identify the zeros of the function shown, identify the values of x in which the graph intersects the horizontal axis.

The amount of people in a population can be determined by using the model y=1000(1.35)x. What is the growth rate?
A.
35%
B.
1.035%
C.
1.35%
D.
3.5%
Answers
Answer:
The growth rate is 35%
Step-by-step explanation:
We are given that the amount of people in a population can be determined by using the model :
[tex]y=1000(1.35)^x[/tex]
Formula of exponential growth : [tex]y=a(1+r)^t ----1[/tex]
Where y is the population in t years
a = Initial population
r = growth rate
The given equation can be written as [tex]y=1000(1+0.35)^x[/tex]
Om comparing it with 1
r = 0.35
So, Growth rate = 35%
Hence The growth rate is 35%

Solve for m. –5 − 5m = –6m
m= _
Answers
Answer:
M = 5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5−5m=−6m
−5+−5m=−6m
−5m−5=−6m
Step 2: Add 6m to both sides.
−5m−5+6m=−6m+6m
m−5=0
Step 3: Add 5 to both sides.
m−5+5=0+5
m=5
Rounded to the nearest hundredths 27.5=3+5(k-9.5)
Answers
Answer:
12 = k
Step-by-step explanation:
Begin: 27.5 = 3 + 5 (k-9.5)
1. Always begin with the parenthesis, which is 5(k-9.5), which comes out to be 5k - 47.5 since the 5 must be multiplied by the k and the -9.5.
Now: 27.5 = 3 + 5k - 47.5
2. Combine the 3 and -47.5, which comes to be -44.5
Now: 27.5 = -44.5 + 5k
3. Add 44.5 to both sides, to make the right side have only the 5k, and the left side to have 72
27.5 + 44.5 = -44.5 + 44.5 + 5k
Now: 72 = 5k
4. Divide both sides by 5 to be left with just what k equals
72/5 = 5k/5
Final Answer: 12 = k

Lulu tells her little brother, Jack, that she is holding 20 coins all of which are dimes and quarters. They have a value of $4.10. She says she will give him the coins if he can tell her how many of each she is holding. Algebraically solve this problem for Jack when x is # of dimes and y is the # of quarters
Answers
Answer:
The answer is 14 quarters and six dimes
Step-by-step explanation:
-.1(D+Q=20)
.10D+.25Q=4.10 -.1D-.1Q=-2
.1D+.25Q=4.10
------------------------------------------------------
.15Q=2.10/.15(both sides)
Q=14 which leaves you needing 60 more cents so 6 dimes
Answer:
6 dimes and 14 quarters
Step-by-step explanation:
x+y=20
0.1x+0.25y=4.1
We can multiply all the numbers in the second equation by 20 to get 2x+5y=82.
Then isolate y to get y=20-x.
Substitute y for 20-x in equation 2 to get 2x+5(20-x)=82
2x+100-5x=82
-3x+100=82
-3x=-18
x=6, and y=20-6, which is 14.
So, Lulu has six dimes and 14 quarters.
The yearly cost in dollars, y, at a video game arcade based on total game tokens purchased, x, is y = y equals StartFraction 1 Over 10 EndFraction x plus 60.x + 60 for a member and y = y equals StartFraction 1 Over 5 EndFraction x. x for a nonmember. Explain how the graph of a nonmember’s yearly cost will differ from the graph of a member’s yearly cost.
Answers
Answer:
The members slope is flatter by half compared to the non-members slope. The graphs intersect at 600 tokens and $120. Until that point the cost for non-members is less than the cost for members. After 600 tokens the cost for members is less than the cost for non-members.
Step-by-step explanation:
I hope I have your equations correct:
Member:
y = 1/10x + 60
Non-Member:
y = 1/5x
The graph of a non-member yearly cost will have a slope of 1/5 and a y-intercept, of 0 while the graph of a member's yearly cost will have a slope of 1/10 and a y-intercept of 60 tokens.
How to solve graphs of straight lineAccording to the question;
For a member; y equals StartFraction 1 Over 10 EndFraction x plus 60.x + 60 for a member.For a member; y equals StartFraction 1 Over 10 EndFraction x plus 60.x + 60 for a member.For a non-member; y equals StartFraction 1 Over 5 EndFraction x.In essence; the mathematical equation for a member is;
y = (1/10)x + 60.For a non-member;
y = (1/5)x.Ultimately, the graph of a non-member yearly cost will have a slope of 1/5 and a y-intercept, of 0 while the graph of a member's yearly cost will have a slope of 1/10 and a y-intercept of 60 tokens.

Answer:
The graph will start at the origin and slope up and to the right.
Using graph, the relationship between time x, and distance from home, y can be shown. The graph will start at the origin and go up to the right the best option is D.
What is graph?A graph is "diagrammatic or pictorial representations of collections of data in a organized manner".
According to the question,
The horizontal line or x-axis of the graph represents time taken during walk and the vertical line or y-axis of the graph represents distance traveled with respect to time.
Since walking start at home is taken as origin in the graph and reaching to school is noted in go up to the right of the graph.
Hence, using graph, the relationship between time x, and distance from home, y can be shown. The graph will start at the origin and go up to the right the best option is D.
