Find the measure of angle N in the triangle . first find the value of y and then plug it in. please show work. help
Answer:
Step-by-step explanation:
By the Isosceles Triangle Theorem, angle O and angle M are congruent because the sides across from each of these angles are congruent. therefore, O = M = 4y - 15. Since, by the Triangle Angle-Sum Theorem all the angles of a triangle have to add up to equal 180 AND angle O and angle M are the same:
7y + 4y - 15 + 4y - 15 = 180 and
15y - 30 = 180 and
15y = 210 so
y = 14. Plug 14 in for y in 7y and get that
∠N = 98°

Identify the outliers, if they exist.
Answer:
189 and 202
Step-by-step explanation:
An outlier is a value that will have an effect on the mean of a set of values. It has an obvious difference compared to other values. They can be easily determined in a set of given data by mere observation.
From the given data in the question, it would be observed that the chronological difference among set of the data is either 1, 2, 3 or 4. But the two numbers that could be referred to as outliers are 189 and 202. This is because the have a wider range than others.

im horrible at math so can some one write down the value to x
Answer:
x = 134 degrees
Step-by-step explanation:
The two angles are alternate interior angles, therefore they equal.
I hope this helped!
It can definitely be a bit tricky to remember all of the different types of angles! But let's see what we've got here.
Our given measures/variables, 134 and x, are both on the inside of the parallel lines (clue: INTERIOR). Then, we can see that they are on opposite sides (clue: ALTERNATE). Therefore, these are alternate interior angles.
Alternate interior angles are congruent, which means that x = 134 degrees.

Type the correct answer in each box.
The value of x is °, and the value of y is °.
Reset Next
Answer:
X=60°
Y=50°
Step-by-step explanation:
Triangles must equal 180° when you add all angles together.
Triangle with angle X
50+70=120180-120=60X=60°To find the value of Y takes a few more steps, but it isn't hard!
Angle Y is on a line, which equals 180° just like a triangle.
We know X=60°, but we don't know what the blank angle equals.
We use the same steps as we did when finding X
60+50=110180-110=70Blank angle=70°We know that the blank angle=70° and that X=60°
Since the line equals 180, we add the two angles and then subtract from 180, just like before!
70+60=130180-130=50 Y=50°Simplify (12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4})(12a 5 −6a−10a 3 )−(10a−2a 5 −14a 4 ) . Write the answer in standard form
Answer:
[tex](12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4}) = 14a^{5}+14a^{4}-10a^{3}-16a[/tex]
Step-by-step explanation:
Given
[tex](12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4})[/tex]
Required
Simplify
We have:
[tex](12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4})[/tex]
Open brackets
[tex]12a^{5}-6a-10a^{3}-10a+2a^{5}+14a^{4}[/tex]
Collect like terms
[tex]12a^{5}+2a^{5}+14a^{4}-10a^{3}-6a-10a[/tex]
[tex]14a^{5}+14a^{4}-10a^{3}-16a[/tex]
Hence:
[tex](12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4}) = 14a^{5}+14a^{4}-10a^{3}-16a[/tex]
which equation represents this number sentence? the product of 10 and a number is 3 less than the number
Step-by-step explanation:
According to the question,
~The product of 10 and a number is 3 less than the number.
Let us suppose the number as n. Writing it in the form of an equation,
→ 10 × Number = Number - 3
→ 10n = n - 3

Find the discriminant for each quadratic function below. Then list the number of zeros/solutions for each quadratic function.
1) 4x^2+10x-16=0
Discriminant________
Number of Zeros__________
2) -16x^2-7x+3=0
Discriminant_______
Number of zeros_________
Answer:
Step-by-step explanation:
The discriminant is found in
[tex]b^2-4ac[/tex] which is part of the quadratic formula. In
[tex]4x^2+10x-16=0[/tex], a = 4, b = 10, c = -16. Filling in for the discriminant:
[tex]10^2-4(4)(-16)=100+256=356[/tex]
It's positive so we know we have real roots; it's not a perfect square, so our solutions are 2 complex rational.
In [tex]-16x^2-7x+3=0[/tex], a = -16, b = -7, c = 3. Filling in for the discriminant:
[tex](-7)^2-4(-16)(3)=49+192=241[/tex]
It's positive and not a perfect square so the 2 solutions are complex rational
The foundation of a house has 1200 termites. The termites grow at a rate of about 3% each day. How many termites are there after one week (round to the nearest termite?
Answer:
1476 termites after 7 days.
Step-by-step explanation:
initial population, P = 1200
rate of growth, r = 1.03
time, t = 7 days
Final population
= Pr^t
= 1200 (1.03^7)
= 1475.8
