Yes it’s 5 1/4
because 4 goes into 21 5 times (5x4=20) so then you have 1 left over.
Answer:
I think it's maybe $55.00
Step-by-step explanation:
Answer:
340.63
Step-by-step explanation:
To find the area we need to calculate the height of the triangle and one of its sides. the bisector cuts the 60° angle in two of 30°. In the picture I drew the triangle and the sides we need to calculate are y and h.
We are going to calculate x, y and h with sin law:
Then, the area of the triangle is
A =
Use the order of operations in order to simplify (solve) the expression
<span>-12 ÷ 3 x (-8 + (-8) - 6) + 2 Original expression
</span><span>-12 ÷ 3 x (-16- 6) + 2 Inside the parenthesis do the addition of the first negatives. -8 +-8 = -16
</span><span>-12 ÷ 3 x (-22) + 2 Inside the parenthesis subtract -16-6 = -22
</span>-4 x (-22) + 2 Multiplication and division is worked from left to right. -12 divided by 3 is -4
88 +2 Multiply -4 x -22 = 88. Two negatives make a positive with multiplication.
90 Addition 88 + 2 = 90
Answer:
y = -1/2x
Step-by-step explanation:
Okay, so you probably heard of the slope-intercept form, y = mx + b. We have to use that formula to create a line that goes through (2,1), because thats the bisector.
Let's have our point start at the origin, (0,0). This you make our equation of y=mx+b <u>into</u> y = mx + 0. Since it's 0, let's just <em>drop</em> it out of our equation.
So now for slope. Rise/Run is what we're going to use to create our slope. Since we started at the origin, our slope is going to be negative. We can go down one over two from the origin to get to points (2,1) so why can't that be our slope? We're rising -1, and running 2, making our slope -1/2. In the equation, it would be y= -1/2x + 0, which can be simplified into y = -1/2x
It's a lot of writing and explaining, so I hope this helps! Try asking your teacher just to make sure it's correct.
