what is the formula for finding missing angles of a triangle
Answer:
Now that you are certain all triangles have interior angles adding to 180° , you can quickly calculate the missing measurement. You can do this one of two ways: Subtract the two known angles from 180° . Plug the two angles into the formula and use algebra: a + b + c = 180°

whats slope intercept form for 2x- 5y=10
Answer:
y=-2/5x-2
Step-by-step explanation:
First, you put x to the other side of the equation so you get y alone, getting the equation of -5y=-2x+10. In order to just have y on one side, you need to divide the whole equation by -5. This leads to the final answer of y=-2/5x-2.

Decide whether there is enough information to prove that a∥b. If so, state the theorem you would use.
Answer: C) Yes, Alternate Exterior Angles Converse
The two red angles are on the outside of the lines a and b, so they are considered exterior. They alternate on either side of the transversal line. So we consider those red angles to be alternate exterior angles. We'll use the alternate exterior angles converse to prove the lines parallel. That converse states: "If alternate exterior angles are congruent, then the lines are parallel".

Answer:
The solution to the inequality is:
[tex]-1\le \:x\le \:3[/tex]
The line graph of the solution is also attached.
Step-by-step explanation:
Given the expression
[tex]4x-1\:\le \:5x\:\le \:3\left(x+2\right)[/tex]
solving the expression
[tex]4x-1\:\le \:5x\:\le \:3\left(x+2\right)[/tex]
[tex]\mathrm{If}\:a\le \:u\le \:b\:\mathrm{then}\:a\le \:u\quad \mathrm{and}\quad \:u\le \:b[/tex][tex]4x-1\le \:5x\quad \mathrm{and}\quad \:5x\le \:3\left(x+2\right)[/tex]
solving
[tex]4x-1\le \:5x[/tex]
Add 1 to both sides
[tex]4x-1+1\le \:5x+1[/tex]
Simplify
[tex]4x\le \:5x+1[/tex]
Subtract 5x from both sides
[tex]4x-5x\le \:5x+1-5x[/tex]
simplify
[tex]-x\le \:1[/tex]
Multiply both sides by -1 (reverse inequality)
[tex]\left(-x\right)\left(-1\right)\ge \:1\cdot \left(-1\right)[/tex]
Simplify
[tex]x\ge \:-1[/tex]
Similarly solving
[tex]5x\le \:3\left(x+2\right)[/tex]
Subtract 3x from both sides
[tex]5x-3x\le \:3x+6-3x[/tex]
Simplify
[tex]2x\le \:6[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}\le \frac{6}{2}[/tex]
Simplify
[tex]x\le \:3[/tex]
So combine the interval
[tex]x\ge \:-1\quad \mathrm{and}\quad \:x\le \:3[/tex]
Merge overlapping intervals
[tex]-1\le \:x\le \:3[/tex]
Therefore, the solution to the inequality is:
[tex]-1\le \:x\le \:3[/tex]
The line graph of the solution is also attached.
If EG = 3y - 10 and ET = 2y, find the value of y In parallelogram FGHI.

Find Value of y.
=====================================
Work Shown:
EI = EG
3y-10 = 2y
3y-10-2y = 0
y-10 = 0
y = 0+10
y = 10
Note how if y = 10, then
EI = 3y-10 = 3*10-10 = 20EG = 2y = 2*10 = 20Both EI and EG are 20 units long when y = 10. This confirms the answer.

Answer:
I think the first option is better.
Step-by-step explanation:
First : 5.75% of $5000 is 287.5. 287.5 * 24 = 6900
And 6.55 of $5000 is 325. 325 * 36 = 117000
If she takes the first option it would be better because it is nearer to what she can afford. It is also better because it helps her make more than 5000 in less time.

The hummingbird population on an island is declining at a rate of 1.4% per year. The population was 5500 in the year 2009.
What is the best prediction of the hummingbird population in the year 2016?
Enter your answer, rounded to the nearest integer, in the box.
The hummingbird population will be
Answer: 4983
Step-by-step explanation:
Initial population P=5500
Population declining at the rate of 1.4%
So, in the year 2010 population is
[tex]P=5500-5500\times1.4\%=5500(1-1.4\%)[/tex]
For the year 2011
[tex]P=5500(1-1.4\%)^2[/tex]
similarly, for the year 2016
no of years passed 2016-2009=7 years
[tex]P=5500(1-1.4\%)^7[/tex]
[tex]P=5500\times0.986^7\\P=5500\times0.90602\\P=4983.117\approx 4983[/tex]

Emma had $2.40 to spend on seven pencils. After buying them she had $1.00. How much did each pencil cost?
Answer:
Each pencil costs 20 cents
Step-by-step explanation:
2.40 - 1 = 1.40
1.40/7 = 0.2
Answer:
$0. 20
Step-by-step explanation:
emma had $2.40 but she spent $1.40 on 7 pencils
if she bought 7 pencils and had $1.00 left
so you would do $2.40 - $1.00 because she had $1.00 left after she bought the pencils.
the answer would be $1.40 because that is how much she spent and you divide that by 7 because she bought 7 pencils.
so 140 divided by 7 = 20
but since its $ dollars you put it into cents leaving you with the answer
$)0.20
Circle C has radius 5 and center C(6,-2). What is the equation of circle C ?
The equation of the circle C is [tex](x-6)^{2}+(y+2)^{2} =25[/tex]
Equation of a circle
The equation of a circle is [tex](x-h)^{2}+(y-k)^{2} =r^{2}[/tex] where r is the radius and (h,k) is the center of a circle.
How to find the equation of a circle for the given condition?The radius of a circle is 5.
Also, the center of a circle is (h,k) = (6,-2)
So, the equation of a circle is [tex](x-6)^{2}+(y-(-2))^{2} =5^{2}[/tex]
Simplify further the above equation.
[tex](x-6)^{2}+(y+2)^{2} =25[/tex]
Thus, the equation of the circle C is [tex](x-6)^{2}+(y+2)^{2} =25[/tex]
