The slope of an angle 30 which in the positive x direction is tanФ = tan30= 1/√3
Slope:
Slope describes the steepness of a line and it also remains constant with the line it also gives us information about the direction. If the slop is negative then the line will be in the negative x-axis if the slop is positive the line will be in the positive x-direction.
A slope of a line is the change in the y coordinate w.r.t the change in the x coordinate.
m = Δy/Δx
m=tan θ = Δy/Δx
m=tan 30 = 1/[tex]\sqrt{3}[/tex]
Therefore the slope of a line that makes an angle of 30 with the positive x direction will be 1/√3

Answer:
[tex] \frac{x - 10}{8} [/tex]
Step-by-step explanation:
[tex] \frac{3x}{8} - \frac{x + 5}{4} [/tex]
The common denominator of both fractions is 8. Therefore,, divide the denominator of each fraction, then multiply what you get by the numerator of each fraction.
Thus:
[tex] \frac{1(3x) - 2(x + 5)}{8} [/tex]
[tex] \frac{3x - 2x - 10}{8} [/tex]
[tex] \frac{x - 10}{8} [/tex]
In a school of 464 students, 89 students are in the band, 215 students are on sports teams, and 31 students participate in both activities. How many students are involved in neither band nor sports?
A.160 students
B.191 students
C.249 students
D.433 students
Answer:
191 students B option is correct
Step-by-step explanation:
Total students=464
In band=89
sports teams=215
Number of students who participates in activities is
215+89=304
31 participate in both activities so,
304-31=273
273 who participate in activities
Total students-273=Not involved in any activity

2(x - 3) = 2x + 5? Need Help Now
Answer: it has no solutions
Step-by-step explanation:
if im wrong i owe u
2(x - 3) = 2x + 5 distribute by multiply 2 into the parenthesis.
2x - 6 = 2x + 5
-2x -2x subtract 2x on both sides, 2x's will cancel on both sides.
____________
-6 = 5
Since -6 = 5, there is no solution because -6 cannot equal to 5, which is a false statement. Thus, "C. There is no solution." is the correct answer. Hope this helps :)

(c) The annual membership fee in 2013 is $198 for each adult and $75 for each child.
Adult = 440 members
Children = 120 members
(i) Calculate the total amount the 560 members pay in 2013.
(ii) The adult fee of $198 in 2013 is 5.6% more than the fee in 2012.
Calculate the adult fee in 2012.
Answer:
i ) $96120
ii ) Singular adult fee in 2012: $186.91
Step-by-step explanation:
( i )
To find the costs of all 560 peoples you:
Multiply the amount of people by the fee,
440 × 198 = $87120
120 × 120 = $9000
Add these go get the sum of member fees: $96120
( ii )
First calculate what 1% of the adult fee would be:
198 ÷ 100 = 1.98 = 1%
Then calculate what 0.1% of the fee:
1.98 ÷ 10 = 0.198 = 0.1%
Now multiply 5 by the value of 1% to get 5% :
5 × 1.98 = 9.9
Then multiply 6 by the 0.1% to get 0.6% :
0.198 × 6 = 1.188
Add these numbers together to get:
1.188 + 9.9 = $11.088 = 5.6%
Due to the fact this question is referring to money we will round this number 2 decimal places (as money does not exceed 2dp)
$11.09
We now subtract this from the 2013 fee to find out the 2012 fee
$198 - $11.09 = $186.91
$186.91 was the cost of a singular adult fee in 2012

Which equation is an identity?
A. –3y + 3 = –3y – 6
B. 9 – (2v + 3) = –2v – 6
C. 3w + 8 – w = 4w – 2(w – 4)
D. 7m – 5 = 8m + 7 – m
Answer:
i think B but I’m not 100% sure lol
Step-by-step explanation:
Here’s what I found on this app
3w + 8 - w = 4w - 2(w - 4)
2w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
0 = 0
Answer: C. 3w + 8 – w = 4w – 2(w – 4)
Identity equations are equations that are true no matter what value is plugged in for the variable. If you simplify an identity equation, you'll ALWAYS get a true statement. Learn about identity equations in this tutorial, and then create your own identity equation.
Step-by-step explanation: Algebra.com
a. 11 - (2v + 3) = -2v - 8
Simplify
11 - 2v - 6 = -2v - 8
5 - 2v = -2v - 8
Add 3v to both sides
5 = -8
That's false, so it is not an identity.
b. 5w + 8 - w = 6w - 2(w - 4)
Simplify
4w + 8 = 6w - 2w + 8
4w + 8 = 4w + 8
That's exactly the same on both sides, so it's
an identity.
c. 7m - 2 = 8m + 4 - m
7m - 2 = 7m + 4
Subtract 7m from both sides:
-2 = 4
That's false, so it is not an identity.
d. 8y + 9 = 8y - 3
Subtract 8y from both sides:
9 = -3
That's false, so it is not an identity.

The number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain is 24m < 256
What is an inequality?An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let m represent the number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain.
Hence:
(48/2)m < 256
24m < 256

Answer:
$75 + $17.50t
$56 + $19.50t
Step-by-step explanation:
Let us assume the number of hours be t
Now according to the equation
For Joe
= $75 + $17.50t
And, for Maddie
= $56 + $19.50t
The expression that represents the total is as
$75 + $17.50t
$56 + $19.50t

Bill plans to save for a pair of headphones that are 89.00.The sales tax rate is 8% how much will bill need to save
Answer: 96.12
Step-by-step explanation:
The amount that Bill will need to save will be for the cost of the headphones and the sales tax that will be applied. This will be:
= 89 + (8% × 89)
= 89 + (0.08 × 89)
= 89 + 7.12
= 96.12
Therefore, Bill will need to save 96.12.
