For a single 20 sided dice, a chance to get a certain number would be 1/20. For 2 numbers it will be a 2/20 chance, which can be simplified to a 1/10 chance that you will roll a 15 or a 17.
Answer:
Equation: 15 - f = n
Answer: n = 9
Step-by-step explanation:
The question is asking to write the equation. The equation would be
"15 - f = n" where f shirts folded
n = shirts remaining to fold
Then the question has gave us the value of f and has told us to solve it. Below is the solution.
15 - 6 = n
=> n = 9
Therefore, there is 9 shirts remaining after 6 of them are folded.
What did we solve?
We wrote our equation and solved what was required in the question.
I hoped this helped.
If possible... May I have brainliest :)
Answer:
m∠A = 30°
m∠B = 80°
m∠C = 70°
Step-by-step explanation:
By applying cosine rule in the given triangle,
b² = a² + c² - 2ac[cos(∠B)]
From the given triangle,
a = 14 m
b = 28 m
c = 24 m
(28)² = (14)² + (24)² - 2(14)(24)cos(B)
784 = 196 + 576 - 672cos(∠B)
cos(∠B) = 0.1786
∠B = 
∠B = 79.71°
∠B = 80°
By applying sine rule in the given triangle,
sinA = 0.491958
A = 29.47°
A ≈ 30°
By applying triangle sum theorem,
m∠A + m∠B + m∠C = 180°
30° + 80° + m∠C = 180°
m∠C = 70°
1. I feel the need to explain things first before I write the numeric value.
Let x be the total number of students in the school. 25% of this value is given to be 35.
(0.25)x = 35
The value of x is 140. 75% of this value is the answer which is equal to 105.
2. Let y be the alternative schools. With this, the number of charter schools is 2x - 6 which is equal to 52
2x - 6 = 52
The value of x is 29. Therefore, there are 29 charter schools.
We know the cofunction identity

Thus, the tangent of 90° minus <span>θ also equals
