its B. 50°
Triangle Have 180°
- 180 - 90 = 90
- 90 × 2 = 180
Half of triangle Have 90°
Answer:
if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.
----------
Note: sin and cos are complementary functions....
sin(x) = cos (90-x)
-------------------
Your Problem:
sin(x-3) = cos(90-(x-3))
Equation:
90-[x-3] = 2x+6
90-x+3 = 2x+6
3x = 93-6
x = 31-2
x = 29
Step-by-step explanation:
For this example, we must combine not permutate; this because a salad in which you first use apple then tomato is the same as the one in which you use first tomato then apple, so order does not matter.
Me must do "10 combine 7" which is written by the binomial coefficient
; in general a binomial coefficient is written by:
In which
and
are positive integers, such that
.
So, for this problem:
Hence, there are 120 different ways to make the fruit salad.
When I took the test, I selected "C. an arrangement in which you receive money now and pay it back later with fees" but I got it wrong. So I'm pretty sure the answer is "A. an arrangement in which you receive money, goods, or services now in exchange for the promise of payment later"
The equation that represents the cost of membership is $100 + $40c
The cost of 1 year membership is $580.
The number of months you have paid for is 9 months.
<h3>What is the equation that represents the cost of the gym membership?</h3>
The cost of gym membership is the sum of the fixed cost and the variable cost. The fixed cost is the start-up fee while the variable cost is the cost per month.
The equation that represents the cost of the gym membership is: c = $100 + $40m
Where m represents the number of months
The cost of 1 year membership = $100 + $40(12)
$100 + $480 = $580
How many months would $460 cover = ($460 - $100) / 40 = 9 months
