Answer:
Polynomial 1:
Simplified Form: 6x^2 - x - 1
Name by Number of Terms: trinomial
Polynomial 2:
Name by Degree: linear
Name by Number of Terms: binomial
Polynomial 3:
Simplified Form: 2
Name by Degree: constant
Step-by-step explanation:
Polynomial 1:
(x-1/2)(6x+2)
6x^2 - 3x + 2x - 1
6x^2 - x - 1
It has 3 terms, so it's a trinomial.
Polynomial 2:
There is one term with x and x is raised to the first degree, so it's linear.
There are 2 terms, so it's a binomial.
Polynomial 3:
4(5x^2-9x+7)+2(-10x^2+18x-13)
20x^2 - 36x + 28 -20x^2 + 36x - 26
28 - 26
2
Since there are no variables and the answer is just 2, it's a constant.

The triangles are congruent. Find the measure of x.
Match up the sides for each triangle using the little marks through the sides
1 to 1, 2 to 2 and 3 to 3
When you do this you see that x corresponds to c on the first triangle.
The 3 angles in a triangle = 180.
Find c by subtracting A and B from 180
C = 180- 29-63 = 88
Now x = c so x = 88
The answer is C. 88

How many times can 3 go into 6?
Answer is 3 times because 2 x 3 is 6.
Answer:
3/1
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 6 and 2 is 2
Divide both the numerator and denominator by the GCD
6 ÷ 2 /2 ÷ 2
Reduced fraction:
3/ 1
Therefore, 6/2 simplified to lowest terms is 3/1.

The value of the internal angle m from the heptagon is given by the equation m = 141°.
What is the sum of a polygon's internal angles?The formula returns the sum of the internal angles of a polygon.
The sum of the internal angles of an n-sided polygon is n = 180° (n - 2), where n is the number of sides = angle in degrees
Given the data,
Let's call the polygon a heptagon.
The polygon has n sides, which equals 7 sides.
Now, n = 180 is the sum of the interior angles of a polygon with n sides ( n - 2 )
7θ = 180 ( 7 - 2 )
7θ = 180 ( 5 )
When we simplify the equation, we obtain 7 = 900°.
A = 900° denotes the sum of the internal angles of the polygon.
And , the value of A = 120° + m° + 148° + 90° + 142° + 130° + 129°
900° = m + 759°
Subtracting 759° on both sides of the equation , we get
m = 141°
Hence , the interior angle ∠B = 141°

Answer:
49π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 14, so r = 14 ÷ 2 = 7, then
A = π × 7² = 49π cm²
Answer:
49pi cm^2
Step-by-step explanation:
[tex]a = \pi \: {r}^{2} [/tex]
Because the radius is half of the diameter, divide it by 2 to get the radius to place in the formula which is 14 ÷2 = 7
so
A = pi × 7^2
A= pi × 49cm^2
Ramona has a booth at a craft show. She sells door
wreaths as a money making project. The booth
costs her $200, and each wreath costs her $10 for
material. If she sells each wreath for $30, how many
wreaths does she have to sell to break even?
Friday, January 8, 2021
Record your answer and fill in the bubbles on
your answer document. Be sure to use the correct
place value
Answer: 10 wreaths
Step-by-step explanation:
First identify the terms.
She has a booth that cost $200. This price will not change thus making it a Fixed cost.
Making a wreath would cost her $10 each time so this is a Variable cost.
She sells the wreath for $30 so this is the selling price.
Breakeven = Fixed Cost / Contribution margin
Contribution margin = Selling price - Variable cost
= 30 - 10
= $20
Breakeven point = 200/20
= 10 wreaths

Pure salt is made up of sodium and chloride. Each gram
of salt contains 0.393 g of sodium. About how much
sodium is in 55.7 g of pure salt?
24 g
29 g
9 g
90 g
Answer:
21.8901 g
Step-by-step explanation:
Given that:
1 gram of pure salt contains 0.393 g of sodium
1 gram = 0.393g
Gram of sodium in 55.7g of pure salt will be x
1g = 0.393g
55.7g = x
Cross multiply:
x = 55.7 * 0.393
x = 21.8901
55.7 g of pure salt will contain about 21.8901 g of sodium chloride

Directed line segment PT has endpoints whose
coordinates are P(-2, 1) and 1(4,7). Determine
the coordinates of pointſ that divides the segment
in the ratio 2 to 1.
Answer:
(2 , 5)
Step-by-step explanation:
point (x,y) that divides the segment PI in the ratio 2 to 1
PD=4 - (-2) = 6 PE/ED=2/1 PE=2ED PE+ED=6 3ED=6 ED=2 PE=4
coordinate of E (2,1) .... 2 is x coordinate of E
DI=7-1=6 DF/FI=2/1 DF=4
coordinate of F (4,5) .... .... 5 is y coordinate of E
CF // PD PC/CI=DF/FI=2/1
C (2,5)
Coordinates of the point intersecting segment PT in the ratio of 2 : 1 will be (2, 5).
Given in the question,
Segment PT with endpoints P(-2, 1) and T(4, 7).Point (h, k) divides the segment in the ratio of 2 : 1.If the endpoints of a segment PQ have been given as[tex]P(x_1,y_1)[/tex] and [tex]Q(x_2,y_2)[/tex] and a point [tex](h,k)[/tex] divides this segment in the ratio of m : n,
[tex]h=\frac{mx_2+nx_1}{m+n}[/tex]
[tex]k=\frac{my_2+ny_1}{m+n}[/tex]
If the extreme ends of a segment PT are [tex]P(-2,1)[/tex] and [tex]T(4,7)[/tex] and a point (h, k) divides this segment in ratio of 2 : 1,
[tex]h=\frac{2(4)+1(-2)}{2+1}[/tex]
[tex]h=2[/tex]
[tex]k=\frac{2(7)+1(1)}{2+1}[/tex]
[tex]k=5[/tex]
Therefore, coordinates of the point intersecting segment PT in the ratio of 2 : 1 will be (2, 5).

How do I find the y-intercept of a graph?
Answer:
the y intercept on a graph is the line that goes up and down
Step-by-step explanation:
Step-by-step explanation:
Every point on the y-axis has 0 as its x-coordinate. The y-intercept is the point of intersection of the graph and the y-axis.
To find the y-intercept, let x = 0 in the equation of the graph and solve for y. The value of y is the y-intercept.
For example, what is the y-intercept of
2x + 3y = 6
Let x = 0.
2(0) + 3y = 6
Solve for y.
3y = 6
y = 2
The y-intercept is 2.
