The local craft fair charges the vendors a flat fee of $15 plus $5 for each hour that they spend at the fair. If the vendor owed how many hours did he remain at the craft fair ?
Answer:
Equation should be: 15x + 5 = y
Step-by-step explanation:
I do not know the amount of money that he owed
For Example :
15(12) + 5 = y
180 + 5 = y
y = 185

What is the slope of a line perpendicular to the line whose equation is
12x + 2y = –12. Fully reduce your answer.
The slope of the line is - 6. Then the slope of the perpendicular line will be 1/6.
What is the equation of a perpendicular line?If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m. The equation is in the form of slope-intercept form. Then the equation of the line is given as
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation of the line is given as,
12x + 2y = - 12
Convert the equation in the slope-intercept form, then the equation will be given as,
Separate the variable y, then the equation is given as,
6x + y = - 12
y = -6x - 12
The slope of the line is - 6. Then the slope of the perpendicular line will be 1/6.

please hurry this is due in an hour and a half
Answer:
See below.
Step-by-step explanation:
We have:
[tex]\frac{\sqrt3}{\sin(\theta)}=2[/tex]
And we want to find two different angles between 0 and 180 that satisfy this equation.
First, let's get our sine out of the denominator. Notice that this is the same as:
[tex]\frac{\sqrt3}{\sin(\theta)}=\frac{2}{1}[/tex]
Cross-multiply:
[tex]2\sin(\theta)=\sqrt{3}[/tex]
Divide both sides by 2:
[tex]\sin(\theta)=\frac{\sqrt{3}}{2}[/tex]
Here you go! I'll have the answer for you if you scroll down, so check it when you're ready!
#2 is correct. However, double check #3. The answer's down there too... :)
[Blank space...]
[More blank space...]
[And more...]
Answer for 1)
We have:
[tex]\sin(\theta)=\sqrt{3}/2[/tex]
So, at what points between 0 and 180 does sine equal √3/2?
If we refer to the unit circle, we can see that this happens twice: at 60.
Thus, the second time it occurs will be at 180-60 or 120.
So:
[tex]\theta=60\textdegree\text{ or } 120\textdegree[/tex]
Answer for 3)
So you are correct for the first three. So:
[tex]\sin(54)=t[/tex]
However, sine stays positive. So, our angle must be between 0 and 180.
So, instead of 180+54, it should be 180-54, giving us:
[tex]\sin(54)=\sin(126)=t[/tex]

2h = W-3p
(solve for p)
Answer:
p = (2h-W)/-3
Step-by-step explanation:
2h - W = -3p
divide both sides by -3
(2h-W)/-3 = p
The value of p is w/3 - 2h/3.
What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S
Given:
2h = W-3p
For p move w
2h - w = -3p
Now, divide both side by 3
2h/3 - w/3 = -3p/3
2h/3 - w/3 = -p
p= w/3 - 2h/3
Hence, the value of p is w/3 - 2h/3.

Answer:
[tex]\boxed {x = 12}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]\frac{5}{6}x + 7 = 17[/tex]
-Subtract both sides by [tex]7[/tex]:
[tex]\frac{5}{6}x + 7 - 7 = 17 - 7[/tex]
[tex]\frac{5}{6}x = 10[/tex]
-Multiply both sides by [tex]\frac{6}{5}[/tex], which is the reciprocal of [tex]\frac{5}{6}[/tex]:
[tex]x = 10 \times (\frac{6}{5})[/tex]
[tex]x = \frac{10 \times 6}{5}[/tex]
[tex]x = \frac{60}{5}[/tex]
-Divide [tex]60[/tex] by [tex]5[/tex]:
[tex]x = \frac{60}{5}[/tex]
[tex]\boxed {x = 12}[/tex]

Convert 6 ounces into grams. Round your answer to the nearest whole
number.
Answer:
170
Step-by-step explanation:
You have to multiply the amount of ounces you want converted by 28.35. Then you have your ounces converted to grams.
If you use this formula then you would have, 170 X 28.35 = 170.1
When you round 170.1 to the nearest whole number you will get 170.
The conversion of 6 ounces into grams is 170 grams.
What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number.
Multiply the number of ounces you want to be converted by 28.35. Use the conversion.
1 ounces = 28 .35 grams
6 ounces = 6 x 28.35 grams
6 ounces = 170 grams.
Hence, 6 ounces is equal to 170 grams.

The ratio of length to width of a rectangular swimming pool is 4 : 5. If the width of the swimming pool is 25 meters, find the perimeter of the pool.
Answer:
20 hrs
Step-by-step explanation:
20 hours: The volume of the pool is (length) × (width) × (height), or 30×10×2=600 cubic meters. Use a standard work equation, RT= W, where W represents the total work of 600 m

.
0.5×t=600
t=1200 minutes
Convert this time to hours by dividing by 60: 1200÷60=20 hours.
Alternatively, you could convert first:

×60min=

Next, use the standard work equation:

t = 20 hours
The perimeter of the rectangular pool would be 90 meters and the length of the pool is 20 meters.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that the ratio of length to width of a rectangular swimming pool is 4 : 5.
Let the length of rectangular swimming pool would be 4x
And the width of rectangular swimming pool would be 5x
Since the width of the swimming pool is 25 meters.
So 5x = 25 ⇒ x = 25/5 = 5
So the length rectangular swimming pool would be 4(5) = 20 meters.
The perimeter of the pool = 2 [ length + width ]
The perimeter of the pool = 2 [ 20 + 25]
The perimeter of the pool = 2 (45)
The perimeter of the pool = 90 meters

Large and small cans of peanuts were sold at a school fundraiser. One student sold
three small cans and nine large cans of peanuts for a total of $75. Another student
sold five small cans and seven large cans of peanuts for a total of $69. What is the
cost of the small and large cans of peanuts?
A Small can for $6.29 and large can for $7.00
B Small can for $4.86 and large can for $6.00
C Small can for $4.00 and large can for $7.00
D Small can for $7.00 and large can for $9.00
Answer:
the answer is c.
Step-by-step explanation:
4 x 5 + 7 x 7 = 69
4 x 3 + 7 x 9 = 75
Cost is small can for $4.00 and large can for $7.00.
What is the system of equation?One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Let S be the number of small cans and L be the number of large cans.
According to the question,
One student sold three small cans and nine large cans of peanuts for a total of $75.
That means the equation is ;
3S + 9L = 75 {equation 1}
And similarly for another student;
5S + 7L = 69 {equation 2}
Now we have two system of the equation.
3S + 9L = 75 {equation 1}
5S + 7L = 69 {equation 2}
Using elimination process,
we multiply 5/3 to equation 1,
5S + 15L = 125
And subtract equation 1 to the equation 2,
we get L = 7 and S = 4
Therefore, small can for $4.00 and large can for $7.00
