Answer:
14.3
Step-by-step explanation:
Remark
Make a rough sketch of the triangle.
Make F the right angle
Make <D = 66
E is the other angle.
Givens
EF = 32
<F = 90
<D = 66
Equation
Tan(D) = EF/FD
Solution
Tan(66) = 32/FD Multiply both sides by FD
FD*Tan(66) = 32
Tan(66) = 2.246
2.246 * FD = 32 Divide by 2.2246
FD = 32/2.246
FD = 14.25
FD = 14.3

A box of 14 raisins cost $2.94 while a box of 12 sunflower seed bags cost $2.40.
Which one is the better deal, based on the unit price?
Answer:
the sunflower seeds are a better deal when comparing unit price. The real question is why are we comparing raisins to sunflower seeds?
Step-by-step explanation:
14 raisins costs $2.94
This is $0.21 per raisin.
12 sunflower seed bags costs $2.40
That's $0.20 per bag.

The measure of the vertex angle of an isosceles triangle is 20 less than twice the measure of each base angle. Find the measure of the vertex angle
Answer:
80
Step-by-step explanation:
Remark
Every triangle has a measure of 180 degrees.
Equation
Let the base angle = x
x + x + 2x-20 = 180
Solution
4x - 20 = 180
4x = 180 + 20
4x = 200
x = 50
Conclusion
Base angle 1 = 50
Base angle 2 = 50
Vertex angle = 2*50 - 20
Vertex angle = 100 - 20
Vertex angle = 80
Write the simplest polynomial function for each set of zeros

PLEASEEEEE HELPPPPPPPPPP
9514 1404 393
Answer:
p(x) = x^4 -5x^3 +20x -16
Step-by-step explanation:
If 'a' is a zero of the polynomial, then (x -a) will be a factor. For the given zeros, the simplest polynomial will be the product of the corresponding factors:
p(x) = (x -2)(x +2)(x -4)(x -1) . . . . . . note that x -(-2) = x +2 (factored form)
__
Multiplying these out gives the result in standard form.
The product of the first two factors is a "special product" recognizable as the difference of two squares.
(x -2)(x +2) = x^2 -2^2 = x^2 -4
The product of the last two factors can be found in the usual way. The distributive property applies.
(x -4)(x -1) = x(x -1) -4(x -1)
= x^2 -x -4x +4 = x^2 -5x +4
Then the full polynomial is the product of these partial products:
p(x) = (x^2 -4)(x^2 -5x +4)
= x^2(x^2 -5x +4) -4(x^2 -5x +4)
= x^4 -5x^3 +4x^2 -4x^2 +20x -16
p(x) = x^4 -5x^3 +20x -16 . . . . . . . . standard form

I still can't afford to fail this semester. The question is in the picture
Answer:
y=1/3x+7/3
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
m=(y2-y1)/(x2-x1)
m=(3-1)/(2-(-4))
m=2/(2+4)
m=2/6
simplify
m=1/3
y=1/3x+b
y-y1=m(x-x1)
y-1=1/3(x-(-4))
y-1=1/3(x+4)
y-1=1/3x+4/3
y=1/3x+4/3+1
y=1/3x+4/3+3/3
y=1/3x+7/3
Find the reference angle of 155o. –25o 25o –65o 65o
Answer:
The reference angle for 155° is 25°
Step-by-step explanation:
The reference angle is the angle that the angle arm makes with the x-axis be it clock wise or anti-clock wise.
The reference angles are obtained by the following reference
0 - 90° => Angle
90° - 180° => 180 - angle
Our given angle is: 155° so we will use the second rule
The reference angle will be:
180° - 155° = 25°
Hence,
The reference angle for 155° is 25°

jeremy ran 4 more miles then twice of kate, k, ran. which expression can be used to represent the situation
Answer:
2k+4
Step-by-step explanation:
Jeremy ran
2k+4
Jeremy ran 4 more miles than twice of Kate.
Given, distance covered by Kate = k
Let distance covered by Jeremy = x
According to Question :
Distance covered by Jeremy = 4 + 2 × distance covered by Kate
Hence, x = 4 + 2k
Therefore, expression used to represent situation is :

Max built a rectangular Prism and a rectangular Pyramid using beach sand. The prism and the pyramid have the same base area and the same height. The amount of sand Max used to build the Prism is how many times the amount used to build the Pyramid?
Answer:
Three times
Step-by-step explanation:
Given
Figures: Rectangular Prism and Rectangular Pyramid
Let the dimension of the prism be:
[tex]l = length[/tex]
[tex]w = width[/tex]
[tex]h = height[/tex]
Amount of sand used is the volume (V1) and it is calculated using;
[tex]V_1 = l * w * h[/tex]
[tex]V_1 = lw h[/tex]
Since the pyramid has the same base area and height as the prism, the its dimension would be:
[tex]l = length[/tex]
[tex]w = width[/tex]
[tex]h = height[/tex]
Amount of sand used is the volume (V2) and it is calculated using;
[tex]V_2 = \frac{1}{3}*(lwh)[/tex]
So, we have:
[tex]V_1 = lw h[/tex]
[tex]V_2 = \frac{1}{3}*(lwh)[/tex]
Substitute lwh for V1 in the second equation
[tex]V_2 = \frac{1}{3}V_1[/tex]
Multiply both sides by 3
[tex]3 * V_2 = \frac{1}{3}V_1 * 3[/tex]
[tex]3 * V_2 = V_1[/tex]
Reorder
[tex]V_1 = 3 * V_2[/tex]
[tex]V_1 = 3 V_2[/tex]
Hence, the amount of sand used in building the prism is three times the amount of sand used in building the pyramid

Mary bought 6 bracelets that cost the same amount and one necklace which cost $86. The items she bought totaled $254 before sales tax was added. What was the cost of each bracelet?
A) $14
B) $56
C) $42
D) $28
1 necklace will therefore cost 34/4 = $8.5
Step-by-step explanation:
She spent between $39 and $59. let us find the average of the amount she spent = 39+59 / 2 = $49.
At an average, she spent $49.
The price of a bracelet is $5 and each bracelet costs the same amount and she bought 3 bracelets = $5 x 3 bracelets each = $15... She spent $15 on the bracelets.
Thus $49 - $15 = amount spent on the 4 necklaces = $34.
4 necklaces cost $34, 1 necklace will therefore cost 34/4 = $8.5
Answer:
Step-by-step explanation:
6x+86=254
subtract 86 from both sides 6x=168
divide both sides by 6 x=28

Answer:
When x=1/2, y=28/3
when x =0, y=9
Equation is y=2/3 x + 9
Step-by-step explanation:
First lets convert them to fractions to make it easier. Also put them in order.
X Y
0
1/2
3/4 19/2
1 29/3
6/5 49/5
You can find the slope since we know 2 points.
(3/4, 19/2) and (6/5, 49/5)
m=3/10 / 9/20
m=2/3
y=2/3 x + b
Lets plug in x and y points to find the y-int
19/2=2/3(3/4) + b
b=9
Therefore y=2/3 x + 9
When x=1/2, y=28/3
when x =0, y=9

Answer:
if ∠PQR ≅ ∠STU, then ∠STU ≅ ∠PQR
We conclude that 'Symmetric Property of Angle Congruence' illustrates this statement.
Step-by-step explanation:
We know that the Symmetric Property of Angle Congruence can be defined as
For any angles X and Y, if ∠X≅∠Y , then ∠Y≅∠XFor example, Let suppose
m∠X = 20m∠Y = 20As ∠X≅∠Y i.e. 20 ≅ 20
then
∠Y≅∠X i.e. 20 ≅ 20
Given
if ∠PQR ≅ ∠STU, then ∠STU ≅ ∠PQR
Thus, we conclude from the above discussion that 'Symmetric Property of Angle Congruence' illustrates this statement.
2x + 28 = 40 and and 2(x + 14) = 40 have different solution steps. Do they have the same solution? Use the distributive property to show why this answer makes sense.
Answer:
yes they are the same
Step-by-step explanation:
2x + 28 =40
you subtract 28 from both sides
2x + 28 - 28 = 40 - 28
2x=12
divide 12 by 2 and get 6
2(6)=12
2(x + 14)= 40
So, 2(x) + 2(14)
2x + 28 = 40
So they're both the same, just with 2 different ways to solve the same equation...Hope this helps!!
The solution for 2x + 28 = 40 is 6.
The solution for 2(x + 14) = 40 is 6.
Yes, they have the same solution.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
2x + 28 = 40
Solve for x.
2x = 40 - 28
2x = 12
x = 6
2(x + 14) = 40
Solve for x.
2x + 28 = 40
2x = 40 - 28
2x = 12
x = 6
Thus,
The solution for both equations is the same.

Lucia is making a 21.6 centimeter beaded string to hang in the window. She decides to put a green bead every 0.4 centimeters and a purple bead every 0.6 centimeters. How many green beads will she need?
Answer: 54 green beads
Step-by-step explanation:
From the question, we are informed that Lucia is making a 21.6 centimeter beaded string to hang in the window and that she decides to put a green bead every 0.4 centimeters and a purple bead every 0.6 centimeters.
The number of green beads that she will need will be gotten by dividing the total length of bead she wants to make by 0.4. This will be:
= 21.6 / 0.4
= 54 green beads
