The answer is 8%. Use the formula SI=PRT
The number of ways by which exactly 2 people are taller than the person behind them is; 6.
<h3>What number of ways can they line so that exactly two people are taller than the person behind them?</h3>
It follows from content that since 4 individuals with different heights are to line up, the 2 individuals who must be taller than the person behind them are represented as one entity and must be in the 1st and 2nd position or the 2nd and 3rd position.
Hence, the number of ways is; 6 upon counting the number of possible outcomes.

Answer:
11) tan(7x+3) = OE/OJ
7x+3=arctan(OE/OJ)=45
x=6
12) a) x = 40
<ajq = <acq (base angles of isosceles triangle)
50+x+90=180
x=40
b) they are congruent triangle, reason HL (hypotenuse, leg)
aj=ac
aq=qa
right angle equal
Answer:
Orginal Speed is 135
Step-by-step explanation:
The ratio of final speed: original speed is
We know that 90 km is it final speed so, we set up a proportion
To solve the equation, subtract 3 from both sides. The solution is k = 11.
A linear equation is an equation of which the highest degree of its variables is 1.
Steps to solve linear equations:
- Simplify the expressions. If there are parentheses, remove them by multiplying the corresponding terms.
- Combine the same terms.
- Isolate the variable on one side by using subtraction of addition.
- Use division or multiplication to find the value of the variable.
Recall that if we subtract or add the same number to both sides of an equation, it does not change the equality.
The given problem:
Solve k + 3 = 14.
The variable is k. Subtract 3 from both sides:
k + 3 - 3 = 14 - 3
k = 11 (solved)
