Step-by-step explanation:
remember 3 things
1. 3 = 3/1 (any integer is also a fraction of itself divided by 1).
2. 3 / 1/6 = 3/1 / 1/6 = 3/1 × 6/1 (dividing by a fraction is the same as multiplying with the upside-down fraction).
3 a/b × c/d = ac / bd. in our case 3/1 × 6/1 = 18/1 = 18
opposite = 1.5.
adjacent = 4.
find the acute angle
Answer:
Step-by-step explanation:
tanθ = opp/adj
θ = arctan(1.5 / 4)
θ = 20.55604521958346...
θ = 20.6°
Answer
20.56
Step-by-step explanation:
tan∅=opposite/adjacent
=1.5÷4
=0.375
then to get ∅ find the tan inverse of 0.375 you'll get 20.55604...
put it in two decimal point...20.56°

How do you rationalize the denominator of a radical expression that has two terms in the denominator? (For example, the denominator is 1+√5.)
Answer:
A / (1 +√5) = A (1 - √5) / (1 - 5) = -A (1 - √5) / 4
Multiply numerator and denominator by (1 - √5)
Justin is buying tickets to a concert online from Ticketmaster. He buys 3 tickets that all have the same price.
There is also a service charge, since he is buying it from Ticketmaster, for $5 per ticket. The total cost of his
order was $138.
Answer:
I don't know if your asking for the price for each ticket, but if you are, it's $41 each.
Step-by-step explanation:
5 x 3 = 15(price of the service charge)
138 - 15 = 123(price with out service tax)
123/3 = 41

y = 2x – 1
replace y with x
x=2x-1
x-2x = - 1
-x = -1
x= 1

10. Saul works two part-time jobs. Last week, he worked 14 hours at a shoe store, and 19
hours as a telemarketer. His total pay was $240.30. The week before, he made
$300.00 for 19 hours at the shoe store and 22 hours telemarketing. Find his hourly
wage for each job
Answer:
shoe store $7.80/hour
telemarketer: $6.90/hour
Step-by-step explanation:
Let s = hourly salary at the shoe store.
Let t = hourly salary as a telemarketer.
14s + 19t = 240.3
19s + 22t = 300
Multiply both sides of the first equation by 19. Multiply both sides of the second equation by -14. Then add them.
266s + 361t = 4565.7
(+) -266s - 308t = -4200
----------------------------------------
53t = 365.7
t = 6.9
Substitute 6.9 for t in the first equation and solve for s.
14s + 19(6.9) = 240.3
14s + 131.1 = 240.3
14s = 109.2
s = 7.8
Answer:
shoe store $7.80/hour
telemarketer: $6.90/hour

A group of 90 students plan to go camping over the weekend. At the last minute, some of the students decide not to go. The students who do go separated into four camps, where [tex]\frac{1}{7}[/tex] of the students stay at Hill Camp; [tex]\frac{1}{3}[/tex] of the students stay at Forest Camp; [tex]\frac{1}{4}[/tex] of the students stay at Field Camp; and the remaining students stay at Lake Camp. How many students were at Lake Camp?
Using fractions, it is found that of the students that went camping, [tex]\mathbf{\frac{23}{84}}[/tex] were at Lake Camp.
The students who went camping are divided according to the following fractions:
[tex]\frac{1}{7}[/tex] stayed at Hill Camp.[tex]\frac{1}{3}[/tex] stayed at Forest Camp.[tex]\frac{1}{4}[/tex] stayed at Field Camp.The remaining x stayed at Lake Camp.The sum of all these fractions is 100% = 1, hence:
[tex]\frac{1}{7} + \frac{1}{3} + \frac{1}{4} + x = 1[/tex]
[tex]\frac{12 + 28 + 21 + 84x}{84} = 1[/tex]
[tex]84x + 61 = 84[/tex]
[tex]84x = 23[/tex]
[tex]x = \frac{23}{84}[/tex]
Of the students that went camping, [tex]\mathbf{\frac{23}{84}}[/tex] were at Lake Camp.

Hey, I just have one question, what is 8y −5 < 3?
Answer:
y < 1
Step-by-step explanation:
In order to solve this inequality, we must isolate the y variable.
First add 5 on both sides of the inequality sign:
Now you have 8y < 8.
Then divide by 8 on both sides, to get y alone:
Now you have y < 1.

If $3000 grows to $3540 after 3 yr, find the simple interest rate
Answer:
R = 6%
Step-by-step explanation:
We know that
SI = A - P
SI = 3540 - 3000
SI = $540
R = 100 × SI/P × T
R = 100 × 540/3000 × 3
R = 54/9
R = 6%
S O L U T I O N:
Here we've been provided with the information i.e
Amount (A) = 3540Principal amount (P) = 3000 Time period (T) = 3 yearsAnd we are asked to calculate simple interest rate (R) = ?
The standard formula to calculate is given by,
[tex]:\Rrightarrow\sf{S.I. = A - P}[/tex]
[tex]:\Rrightarrow\sf{S.I. =3540 - 3000}[/tex]
[tex]:\Rrightarrow\sf{S.I. =540}[/tex]
[tex]:\Rrightarrow\sf{R = 100 \times \frac{S.I.}{P} \times t}[/tex]
[tex]:\Rrightarrow\sf{R = 100 \times \frac{540}{3000} \times 3}[/tex]
[tex]:\Rrightarrow\sf{R = \frac{54}{9} }[/tex]
[tex]:\Rrightarrow\sf{R = 6\%}[/tex]
The simple interest is 6%.which car can travel furthur on one gallon of gas/ green car 18.4 miles on 0.8 gallons or black car 17.4 miles on 0.75 gallons
Answer:
The black car
Step-by-step explanation:
First, we need to fin the mile to gallon ratio.
To get this we would divide the number of miles by the gallon for each car
Green Car:
18.4/0.8
23 miles per gallon
Black car:
17.4/0.75
23.2 miles per gallon
In conclusion, The black car would travel further on one gallon of gas than the green car would.

There is a line that includes the point (1,6) and has a slope of 4. What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y=4x+2
Step-by-step explanation:
So we start with the slope, which is bad.
But I have an idea
lets write it as
y=4x+? and since x=1 and y=6
6=4+?
Therefore, the y, intercept must be two
Answer:
y=4x+2
Step-by-step explanation:
y-y1=m(x-x1)
y-6=4(x-1)
y=4x-4+6
y=4x+2
Find the slope of the line that passes through (6, 8) and (2, 17).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
-9/4
Step-by-step explanation:
Slope is equal to the change in y, over the change in x, or rise over run.
x, is the run
y, is the rise
You can substitute the coordinate numbers on the equation to find the slope. which is y2-y1/x2-x1
m= 17-(8)
——
2-(6)
Your answer will be -9/4 (it doesn’t matter where the negative goes, and there’s a negative because 2-6= -4)

O x=0
O x=0 or x = -6
O x= 0 or x = 6
O no solution
Answer:
x=0 or x=6
Step-by-step explanation:
-4|-2x+6| = -24
|-2x+6| = 6
-2x+6 = 6
-2x = 0
x = 0
-2x+6 = -6
-2x = -12
x = 6
Therefore, x=0 or x=6

Answer:
slope is -3
y intercept is 6
Step-by-step explanation:
The y intercept is where it crosses the y axis
It crosses the y axis at 6
We need two points to find the slope (0,6) and (2,0)
m = ( y2-y1)/(x2-x1)
= (0-6)/(2-0)
= -6/2
= -3
The slope is -3
