How high up the wall does the ladder reach is 17.21 ft.
To solve the question, we need to know what right-angled triangles are.
What is a right-angled triangle?A right-angled triangle is a triangle in which the angle facing the longest side is 90°.
The required right-angled triangleThe ladder, the ground and the wall form a right angled triangle with hyptenuse side, length of ladder, L and opposite side to angle between ground and ladder, Ф = 73° is h. Opposite side equals height of ladder along wall, h.
How high up the wall does the ladder reach?
From trigonometric ratios
sinФ = h/L
h = LsinФ
Substituting the values of the variables into the equation, we have
h = LsinФ
h = 18 ft × sin73°
h = 18 ft × 0.9563
h = 17.21 ft
So, how high up the wall does the ladder reach is 17.21 ft.

Acids increase the concentration of hydronium ions in solution by donating hydrogen ions to water molecules. true false
The statement about Acids increasing the concentration of hydronium ions in solution is; True
What is the concentration of the solution?In pure water and in neutral solutions, we know that the Hydroxonium ions [H₃O⁺] and Hydroxyl Ions [OH⁻] are equal. Therefore, [H₃O⁺] = [OH⁻] = 1 * 10⁻⁷.
However, that concentration can be altered by the addition of an acid or abase. Thus, If an acid is added to pure water the concentration of hydronium ions in the solution will increase.

Assume that louisa carried an average balance of $1,000 from her credit card purchases over the past year. the a.p.r. on her credit card for the past year was 19.99%. approximately how much interest would louisa have paid over the course of the year?
The approximate amount of interest that louisa would have paid over the course of the year is; $200.
How to Calculate Simple Interest?The amount of interest accrued in simple interest is given by the formula:
E = P*i*t
Where;
P is the balance.
i is the interest rate.
t is the time.
We are given;
Balance; P = $1,000, hence
APR of 19.99% and so i = 0.1999
time; t = 1 year.
Thus, the amount she will pay is:
E = 1000 * 0.1999 * 1
E = $199.9
Approximating to a whole number gives;
E = $200

Give (in order) the correct coefficients to balance the following reaction: h2sncl6 + h2s → sns2 + hcl
Let a, b, c, and d be coefficients in the balanced reaction,
a H₂SnCl₆ + b H₂S → c SnS₂ + d HCl
Count the atoms on both sides and set the amounts equal to each other:
• H : 2a + 2b = d
• Sn : a = c
• Cl : 6a = d
• S : b = 2c
Suppose a = 1. Then
6a = d ⇒ d = 6
2a + 2b = d ⇒ b = (d - 2a)/2 = 2
b = 2c ⇒ c = b/2 = 1
So, the balanced reaction is
1 H₂SnCl₆ + 2 H₂S → 1 SnS₂ + 6 HCl
The correct coefficients in order to balance the reaction is 1, 2, 1, 6
How to determine the correct coefficients to balance the equation?To obtain the correct coefficients in order to balance the reaction, we shall obtain the balance equation. This is shown below:
H₂SnCl₆ + H₂S → SnS₂ + HCl
There are 2 atoms of S on the right side and 1 atom on the left side. It can be balanced by writing 2 before H₂S as shown below:
H₂SnCl₆ + 2H₂S → SnS₂ + HCl
There are 6 atoms of Cl on the left side and 1 atom on the right side. It can be balanced by writing 6 before HCl as shown below:
H₂SnCl₆ + 2H₂S → SnS₂ + 6HCl
Now, the equation is balanced. Thus, the correct coefficients needed to balance the reaction is 1, 2, 1, 6

The average height of sunflowers in a field is 64 in
This is from https://www.jiskha.com/questions/1578462/a-the-average-height-of-sunflowers-in-a-field-is-64-inches-with-a-standard-deviation-of
Answer:
a) The graph of a normal curve with a mean of 64" and a standard deviation of 3.5" is a bell-shaped curve with its
maximum value at x = 64.
Important points:
mean - 3 deviations: 64 - 3(3.5) = 64 - 10.5 = 53.5
mean - 2 deviations: 64 - 2(3.5) = 64 - 7 = 57
mean - 1 deviation: 64 - 3.5 = 60.5
mean: = 64
mean + 1 deviation: 64 + 3.5 = 67.5
mean + 2 deviations: 64 + 2(3.5) = 64 + 7 = 71
mean + 3 deviations: 64 + 3(3.5) = 64 + 10.5 = 74.5
b) If there are 3000 plants, approximately how many will be taller than 71"?
71" is 2 standard deviations above the mean. The region between two standard deviations below the mean and two standard deviations holds approximately 95% of the plants.
Therefore there will be approximately 5% of the plants divided equally between being taller than two standard
deviations above the mean and being shorter than two standard deviations below the mean. Thus, there will be
approximately 2.5% of the plants taller than 71": 0.025 x 3000 = 75 plants.
