A 17-foot ladder is leaning on a tree. The bottom of the ladder on on the ground at a distance of 8 feet from the base of the tree. The base of the tree and the ground form a right angle as shown.
[ not drawn to scale ]
What is the distance, in feet, between the ground and the top of the ladder?
Answer:
15 feet
Step-by-step explanation:
Since, it's a right triangle, we will use the Pythagorean theorem formula:
[tex]a^2+b^2=c^2[/tex]
a and b are the straight sides and c is the ladder (hypotenuse).
[tex](8)^2+b^2=(17)^2[/tex]
Solve for [tex]x[/tex]:
[tex]64+b^2=289[/tex]
[tex]b^2=225[/tex]
[tex]\sqrt{b^2} =\sqrt{225}[/tex]
[tex]b=15[/tex]
The distance between the ground and the top of the ladder is 25 feet.
what is Pythagoras Theorem?The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.
Given:
Hypotenuse= 17 foot
Base = 8 feet
Now, using pythagoras theorem
H² = P² + B²
17² = P² + 8²
289 - 64 = P²
P= √225
P= 25 foot
Hence, the distance between the ground and the top of the ladder is 25 feet.

Graph y=−83x+9.
Identify the x-intercept.
Answer:
x-intercept=-74
Step-by-step explanation:
for x-intercept (y=0)
y=83x+9
0=83x+9
-83x=-0+9
-83x=9
x=9/-83
x=-0.1
Answer:
x = -27/8
Step-by-step explanation:
y = [tex]\frac{8}{3} x + 9[/tex]
to find x intercept let y = 0 then solve for x
0 = [tex]\frac{8}{3} x + 9[/tex]
-9 = [tex]\frac{8}{3} x[/tex]
divide both sides by 3
-9x3 = 8x
-27 = 8x
8x = -27
x = -27/8

It costs $20.50 to enter an amusement park and $0.25 to ride a ride. You have $21.50. Write an equation that represents the number r of rides you can ride.
Answer:
4 rides
Step-by-step explanation:
Total amount = $21.50
Entry charge = $20.50
Amount left = $21.50 - 20.50 = $1
Number of rides
[tex]r = \frac{1}{0.25} = \frac{100}{25} = 4 \\ [/tex]
Another way:
[tex] 0.25\:r + 20.50 = 21.50\\
0.25\:r = 21.50 - 20.50\\
0.25\:r = 1\\
r = \frac{1}{0.25}\\
r = \frac{100}{25}\\
r = 4\\[/tex]

Answer:
there are 12 sections in total and 3 green sections
3 wanted sections /12 total sections = 1/4 chance to get green
hope this helps
Step-by-step explanation:
Probability of spinning green on the spinner is equals to [tex]\frac{1}{4}[/tex] .
What is probability?" Probability is defined as the mathematical statement which represents the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Total number of spinning colour in a spinner = 12
Number of green spinner = 3
Substitute the value in the formula to get the probability we get,
Probability of spinning green = [tex]\frac{3}{12}[/tex]
= [tex]\frac{1}{4}[/tex]
Hence, probability of spinning green on the spinner is equals to [tex]\frac{1}{4}[/tex] .

What is the probability that a randomly chosen bag does NOT contain a
forbidden item?
P(not forbidden) =
Answer:
.95 is the correct answer. See screenshot below
Step-by-step explanation:
The probability that a randomly chosen bag does NOT contain a forbidden item is 0.95
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, 5% of bags contain forbidden items.
We know that, the probability of an event not happening is 1 minus the probability of the event happening,
Therefore, the probability that a randomly chosen bag does NOT contain a forbidden item = 1-0.05 = 0.95
Hence, the probability that a randomly chosen bag does NOT contain a forbidden item is 0.95

Which of the following systems of inequalities has point D as a solution?
f(x) ≤ 3x + 4
g of x is less than or equal to negative one half times x minus 5
f(x) ≥ 3x + 4
g of x is less than or equal to negative one half times x minus 5
f(x) ≤ 3x + 4
g of x is greater than or equal to negative one half times x minus 5
f(x) ≥ 3x + 4
g of x is greater than or equal to negative one half times x minus 5
Answer:
B) f(x) ≥ 3x + 4
g of x is less than or equal to negative one half times x minus 5
Step-by-step explanation:
From the above graph,
If point B is the solution of the system of inequalities, then point B must satisfies both inequalities
We can see from the graph that
Point B is located above (≥) the boundary line for f(x) and is also below (≤) the boundary line for g(x).
So we can say,
Point b satisfies the inequalities
Therefore,
The system is
f(x) ≥ (3x+4)
g(x) ≤ (-1/2x -5)

Sam is eating a Big Hamburger. The first bite was 20% of the Hamburger, the second bite was 20% of what is left and so every next bite is 20% of what is left.
a) How much did the Hamburger weigh originally, if after the second bite there was 160g of it left?
Answer:
250g
Step-by-step explanation:
To calculate the original weight, you just have to find how much was left of the hamburger after the second bite.
Say that the hamburger is x grams.
0.64x = 160
x = 250

The sum of two positive integers is 12. When the smaller integer is subtracted from five times the larger, the result is 36. Find the two integers.
Answer:
The smaller integer is 4 and larger integer is 8 .
Step-by-step explanation:
First we have to form own variables and expression. So we let the smaller integer be x and the larger integer be y. Next using the information given to form expressions :
[tex]x + y = 12 \\ 5y - x = 36[/tex]
Lastly, we can solve the simultaneous equation using Elimination :
[tex]x + y = 12 - - - (1)[/tex]
[tex] - x + 5y = 36 - - - (2)[/tex]
[tex](1) + (2)[/tex]
[tex]x + ( - x) + y + 5y = 12 + 36[/tex]
[tex]6y = 48[/tex]
[tex]y = 8[/tex]
[tex]sub \: y = 8 \: into \: (1)[/tex]
[tex]x + 8 = 12[/tex]
[tex]x = 4[/tex]
Solve this system of linear equations. Separate
the x- and y-values with a comma.
-5x + 3y = 13
7x + 2y = -12
Answer:
x = -2, y = 1
Step-by-step explanation:
So you can solve this equation using subtraction.
Multiply the first equation by 2:
-10x + 6y = 26
Multiply the second equation by 3:
21x + 6y = -36
Subtract the two equations:
-31x = 62
x = -2
y = 1
