Answer:
125 traffic cones
Step-by-step explanation:
In order to find the total number of meters, we can set up a proportion to find based on the ration of cm to m:
, where 'x' is the number of meters
cross-multiply: x = 25(50) or x = 1250 m
Since there is a cone every 10 m, we can divide the total number of meters by 10:
1250/10 = 125 cones
Answer:
12.22
Step-by-step explanation:
To find HI, you have to use tangent. tanx=
tan(42°)= , then you multiply HI to both sides of equation and divide tan(42).
To get <em>HI</em>=
Which makes HI equal 12.2167
Answer:
n = , n =
Step-by-step explanation:
6n² - 5n - 7 = - 8 ( add 8 to both sides )
6n² - 5n + 1 = 0 ← in standard form
Consider the product of the factors of the coefficient of the n² term and the constant term which sum to give the coefficient of the n- term
product = 6 × 1 = 6 and sum = - 5
The factors are - 3 and - 2
Use these factors to split the n- term
6n² - 3n - 2n + 1 = 0 ( factor the first/second and third/fourth terms )
3n(2n - 1) - 1(2n - 1) = 0 ← factor out (2n - 1) from each term
(2n - 1)(3n - 1) = 0 ← in factored form
Equate each factor to zero and solve for n
3n - 1 = 0 ⇒ 3n = 1 ⇒ n =
2n - 1 = 0 ⇒ 2n = 1 ⇒ n =
