Henry is painting a house. He placed a 24 foot ladder 15 feet away from the base of the house so that it leaned up against the house.
Enter the measure of the angle that is formed between the ladder and the ground, rounded to the nearest tenth.
Answer:
51.3 degrees
Step-by-step explanation:
Use Trig Ratio to solve for theta aka the angle formed between the ;adder and the ground.
So we have the hypotenuse = 24ft and the adjacent = 15ft so I am going to use the cos ratio.
cos ∅ = a/h
rearrange for theta
∅ = cos -1 ( a/h)
now sub in the information
∅ = 51.3178
now round to the nearest tenth
∅ = 51.3 degrees
write your therefore statement
therefore, the angle between the ladder and the ground is 51.3 degrees.
Refer to the isosceles trapezoid shown. Find z

Find the distance between the points given.
(-1, -1) and (1, 3)
√5
√(17)
2√5
Answer:
2√5
Step-by-step explanation:
d = √(x2 - x1)² + (y2 - y1)²
= √[1 - (-1)]² + [3 - (-1)]
= √(2)² + (4)²
= √(4) + (16)
= √20
= 2√5

Answer:
Step-by-step explanation:
LA = pi*r*l = 3.14*8.5*12.4 = 331
SA = LA + pi*r^2 = 331 + 3.14*8.5^2 = 558
V = 1/3*pi*r^2*h = 1/3*3.14*(8.5^2)*sqrt(12.4^2-8.5^2) = 683
Answer:
331
558
683
Step-by-step explanation:
LA = 3.14x8.5x12.4 = 330.9 = 331
SA = 331+3.14x8.5^2 = 557.9 = 558
V = 1/3x3.14x(8.5^2)x(12.4^2-8.5^2)^0.5 = 682.7 = 683
A company logo is shaped like an equilateral triangle with 6-inch long sides. What is the height of the logo? Round to the nearest tenth.
Answer:
5.2 in
Step-by-step explanation:
An equilateral triangle is a triangle with 3 equal sides
Divide the equilateral triangle into two congruent triangles and use Pythagoras theorem to find the height
The Pythagoras theorem : a² + b² = c²
where a = height
b = base = 6 in / 2 = 3 in
c = hypotenuse = 6 in
6² = 3² + h²
h = 36 - 9 = 27
√27 = 5.196 inch
to the nearest tenth = 5.2 in
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Anthony has $3750 that he wants to invest. He plans to leave the money there for 9 years. If his investment gets 6.35% interest compounded continuously, how much will he have at the end of 9 years? Round your answer to the nearest whole number?
Answer:
[tex]A= P(1+\frac{r}{n})^{nt}[/tex]
P = 3750
r = 6.35% = 0.0635
n = 365
t = 9
[tex]A= 3750(1+\frac{0.0635}{365} )^{365*9}\\\\[/tex]
[tex]= 3750(1+\frac{0.0635}{365})^{3285} = 6640.63[/tex]
Answer = $6641

Based on statistics for the past several seasons, the probability that the best player on a basketball team makes a free throw is 8/10. the probability that the second-best player makes a free throw is 13/20. if both players attempt 140 free throws over a season, how many more free throws is the best player expected to make? Please help!!!
Answer: The best player is expected to make
21 more free throw(s).
Step-by-step explanation:
1) Make a proportion
2) Find the unknowns
3) Subtract the greater number from the smaller one
4) That's it.
Answer:
He is expected to make 21 more free throws
Step-by-step explanation:
we know that the probability for the best player is 8/10 or 80%
the probability for the second best is 13/20. This is equivalent to 65%
They each attempt 140 free throws.
We need to figure out what 80% of 140 is. To do this, we need to multiply 140 by 0.80. 140 * 0.80 = 112
We do the same for the second best
140 * 0.65 = 91
112 - 91 = 21.

The probability that Gerald makes a three-point shot in basketball is 20\%20%20, percent. For practice, Gerald will regularly shoot a series of these shots until he succeeds at one. He's curious how many shots it will typically take him to get his first successful shot.
He simulated 404040 trials of three-point shots where each shot had a 0.20.20, point, 2 probability of being successful, and in each trial, he counted how many shots it took to get the first successful shot. Here are his results:
Use his results to estimate the probability that it takes 101010 or fewer shots to get his first successful shot.

Answer:
[tex]P(x \le 10) = 0.85[/tex]
Step-by-step explanation:
Given
See attachment for properly presented question
Required
[tex]P(x \le 10)[/tex]
From the question, we understand that he takes 40 shots (trials)
So:
[tex]n = 40[/tex]
From the attached plot, the number of attempts up to the 10th is:
[tex]x \le 10 = 9+6+5+4+4+2+2+0+1+1[/tex]
[tex]x \le 10 = 34[/tex]
So, we have:
[tex]P(x \le 10) = \frac{n(x \le 10)}{n}[/tex]
[tex]P(x \le 10) = \frac{34}{40}[/tex]
[tex]P(x \le 10) = 0.85[/tex]

What is the volume of the cylinder below? 9- 7 - 5 OA. 1757 units3 B. 2257 units3 C. 357 units3 D. 70n units3
Answer:
175 pi ^3
Step-by-step explanation:
The volume of the cylinder is 175π cubic units or 175π units³ if the radius of the base r is 5 units and the height of the cylinder h is 7 units option (A) 175π units³ is correct.
What is a cylinder?In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.
We know the volume of the cylinder is given by:
[tex]\rm V = \pi r^2 h[/tex]
Volume can be defined as a three-dimensional space enclosed by an object or thing.
As we know,
We can find the volume of the cylinder by using the given formula:
[tex]\rm V = \pi r^2 h[/tex]
The radius of the base r = 5 units
The height of the cylinder h = 7 units
[tex]\rm V = \pi (5)^2 (7)[/tex]
V = 25x7π
V = 175π cubic units
Or
V = 175π units³
Thus, the volume of the cylinder is 175π cubic units or 175π units³ if the radius of the base r is 5 units and the height of the cylinder h is 7 units option (A) 175π units³ is correct.

Help pls 6th grade math (look at the pic attached) btw it’s 2 questions
Answer:
1. s=7
2 s = 8
Step-by-step explanation:
s + 12 =19 you subtract 12 from 19 and you get 7 so you rewrite it like this s = 7 then divide s by 7 and get s = 7
s - 6=2 add 6 to both sides so 6+2 equals 8
s=8
Help please?!?!??!?!!!?!?!?!?!?!?!?!!?!?!?
Answer:
60%
Step-by-step explanation:
Number of people ages 26 - 35 prefer Ad A = 12
Number of people ages 26 - 35 prefer Ad B = 8
Total people ages 26 - 35 = 12 + 8
= 20
Percent of people ages 26 - 35 prefer Ad A = Number of people ages 26 - 35 prefer Ad A / Total people ages 26 - 35 × 100
= 12/20 × 100
= 0.6 × 100
= 60%
Percent of people ages 26 - 35 prefer Ad A = 60%

Answer:
(Square, Right Triangle)
18 meters²
Step-by-step explanation:
You can divide the shape into a square and right triangle, see the attachment :)
The area of the square is the length times the width. So,
3 · 3 = 9
The area of the square is 9 m².
The triangle's area is the base times the height divided by 2. So,
6 · 3 = 18
18 / 2 = 9
The triangle has an area of 9 m².
Add these together.
9 + 9 = 18
The area is 18 meters².
