Answer: 8
Step-by-step explanation:
We can use trigonometry to solve this:
If we call the angle at the top Ф then x is the opposite and 8 is the adjacent
Therefore we use Tan to solve this:
Tan Ф = opposite/adjacent
Tan 45 = X/8
1 = X/8
8 x 1 = X
Therefore X = 8

Answer: (The first number will be for the side on the left and the second will be for the on the right it matches with) (1, 3) (2, 1) (3, 5) (4,2) (5, 4)
Step-by-step explanation:
The nomial number(prefix) is determined by how many terms are in a parentheses. For example, The first one (3z) (9z) has one term bc 3z is one tern and 9z is one term so they are both monomials but b-1 would be a binomial because it has two terms so knowing that should explain my answers
Factor x3y6 + 27z42. (xy3 + 3z39)(x2y9 – 3xy3z39 + 9z1,521) (xy3 + 3z39)(x2y6 – 3xy3z39 + 9z78) (x3y6 + 27z42)(x6y12 – 27x3y6z42 + 729z84) (xy2 + 3z14)(x2y4 – 3xy2z14 + 9z28)
Answer:
[tex]x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})(x^2y^4 - 3xy^2z^{14} + 9z^{28})[/tex]
Step-by-step explanation:
Given
[tex]x^3y^6 + 27z^{42[/tex]
Required
Factor
Express both terms as a cube
[tex]x^3y^6 + 27z^{42} = (xy^2)^3 + (3z^{14})^3[/tex]
Let
[tex]a =(xy^2)[/tex]
[tex]b = (3z^{14})[/tex]
So:
[tex]x^3y^6 + 27z^{42} = a^3 + b^3[/tex]
Using sum of cubes:
[tex]a^3 + b^3 = (a + b)(a^2 - ab + b^2)[/tex]
So:
[tex]x^3y^6 + 27z^{42} = (a + b)(a^2 - ab + b^2)[/tex]
Substitute in, values of a and b
[tex]x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})((xy^2)^2 - (xy^2)*(3z^{14}) + (3z^{14})^2)[/tex]
[tex]x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})(x^2y^4 - 3xy^2z^{14} + 9z^{28})[/tex]

Answer:
$13.50
Step-by-step explanation:
So excluding tax and tip, let's find the cost of the meal.
$6.70 + $1.95 + $2.35 = $11.00
Now let's add the 4.5% tax. We do this by adding 4.5% of 11.00 to 11.00
$11.00 + 0.045($11.00) = $11.495 which rounds to 11.50
Now the tip is 2 dollars, so add 2 to 11.50 to get $13.50

Answer:
13. PS = 21.37
14. 68.74°
Step-by-step explanation:
13. QS/39 = tan 28
QS = 39 tan 28
sin 76 = QS/PS
PS sin 76 = QS
PS = QS/sin 76
= 39 tan 28/sin 76
= 21.37
14. tan 47 = BD/18
BD = 18 tan 47
cos CDB = 7/BD
= 7/(18 tan 47)
m∠CDB = arccos [7/(18 tan 47)
= arccos .362644...
= 68.74°
The trigonometry we get PS = 21.37 and m∠CDB= 68.74°

What is the formula of tan?The value of tan is opposite side/adjacent side
Therefore we get
13. QS/39 = tan 28
QS = 39 tan 28
sin 76 = QS/PS
PS sin 76 = QS
PS = QS/sin 76
PS = 39 tan 28/sin 76
PS = 21.37
14. tan 47 = BD/18
BD = 18 tan 47
cos CDB = 7/BD
cos CDB= 7/(18 tan 47)
m∠CDB = arccos [7/(18 tan 47)
m∠CDB = arccos .362644...
m∠CDB = 68.74°

What is the ratio?A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.
Given that,
A new color of green requires 5 yellow to 4 parts blue
The paint mixer used 30 gallons of yellow
The number of gallons of blue color needed = ?
Ratio of yellow to blue in mixture = 5/4
So, if 30 gallons of yellow is used
then gallons of blue = ?
Suppose, gallons of blue = x
5/4 = 30/x
x = 24
Hence, the gallons of blue is 24

Write an exponential decay model for each situation. The value of x for each value of f(x) will lie between two consecutive whole numbers. List the whole numbers.
initial value: 1,800
decay rate: 7%
f(x) = 400
Answer:
The numbers are;
20 and 21
Step-by-step explanation:
A general form of an exponential decay model can be presented as follows;
f(x) = a·(1 + r)ˣ
Where;
f(x) = The output for a given input variable, 'x'
x = The input variable
a = The initial value
r = The growth (+ve) or decay (-ve) rate
When f(x) = 400, a = 1,800, r = -7% = -0.07, we get;
400 = 1,800 × (1 - 0.07)ˣ
(1 - 0.07)ˣ = 400/1,800 = 2/9
ln((1 - 0.07)ˣ) = ln(2/9)
x = ln(2/9)/(ln(1 - 0.07)) ≈ 20.73
The value of 'x' lies between 20 and 21.

Answer:
incorrect, is you plug in the x, y=2x-1, y=60-1, or y=59,
Answer:
Jenna is not correct.
Step-by-step explanation:
If we subsitute the y in the equation with 61 and subsitute x with 30, it would be: 61 = 30*2-1. However 30*2-1=59 therefore it is incorrect.

A. 113.5°
B. 47.5°
C. 46.5°
D. 180°
Answer:
C
Step-by-step explanation:
19.9 + 113.6 = 133.5
180-133.5= 46.5
Answer:
[C] 46.5°
Step-by-step explanation:
Given:
In triangle xyz, angle x measures 19.9° and angle
y measures 113.6°. what is the measure of angle z
Note that:
Triangle = 180 degree
Solution:
Since,
x = 19.9 degree
y = 113.6 degree
then we have:
19.9 + 133.6 + z = 180
133.5 + z = 180
Subtract both sides by 133.5
133.5 - 133.5 = 180 - 133.5
x = 46.5 degree
Hence, the measure of angle z is 46.5
Also means that [C] 46.5 is the correct answer.

Answer:
760ft
Step-by-step explanation:
First you find the volume of the rectangle thing :)
so 14 times 19 times 2 = 532ft
than you need to do the triangle so 20 - 14 (for base length) is 6
so 19 times 6 times 2 = 228ft
now you ad them, so 532 + 228 = 760
