Answer:
No solutions; parallel
Step-by-step explanation:
The equations x=16 and x=3 both have a slope of 0. So when graphed, they would be parallel and there are no solutions between parallel lines.
Your class wants to raise more than $350 for the Freshman Party and you choose to sell candy and cookies to accomplish this task. You earn $6 on each basket of candy, b, and $3 on each box of cookies, c, that you sell. If the number of boxes of cookies sold is 78, at least how many baskets of candy will you need to sell to reach your goal?
Answer:
16 baskets of candy.
Step-by-step explanation:
78 boxes of cookies times $3 per box equals $234.
$350-$234=$116 left you need to make so-
each basket of candy earns $6, divide $116 by $6 to equal 56.
You will need to sell 56 baskets of candy at $6 each to reach your goal of $350 .
Evelyn bought 60 tickets for rides at an amusement park. Each ride costs 3 tickets, and Evelyn has been on x rides so far. Select all the expressions that show the number of tickets that Evelyn has left.
Answer:
I believe your answer will be E, A, and C
Step-by-step explanation:
If she has 60 tickets and each ride is 3 tickets but she has been on x rides you would do 3x and subtract that from 60.
Answer:
a,c,e
Step-by-step explanation:
60 is the total number of tickets, so b and d are wrong because you are no adding to the total number of tickets.

is the point (1,-3) a solution to the system? show all your work
y>x-1
y >-x+2
Answer:
To determine if the point is a solution, substitute the x value into the right side of the inequality and compare the result with the y value of the point.
- x + 2 = - 1 + 2 = 1
Now - 3 < 1
Thus (1, - 3) is not a solution

Jim invests $1240 at a 3.6 interest rate in an account that is compounded quarterly. What is the value of the account after 6 years
Answer:
$1507.84
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.6%/100 = 0.036 per year,
then, solving our equation
I = 1240 × 0.036 × 6 = 267.84
I = $ 267.84
The simple interest accumulated
on a principal of $ 1,240.00
at a rate of 3.6% per year
for 6 years is $ 267.84.

Answer:
[tex]x \approx 24\degree [/tex]
Step-by-step explanation:
In triangle BAC, by Pythagoras theorem:
[tex]AC^2 = BC^2 -BA^2 [/tex]
[tex]AC^2 = (15)^2 -(9)^2 [/tex]
[tex]AC^2 = 225 - 81[/tex]
[tex]AC^2 = 144[/tex]
[tex]AC = \sqrt {144} [/tex]
[tex]AC = 12\: cm [/tex]
In triangle ABD,
[tex] \tan \angle ABD =\frac{AD}{AB} [/tex]
[tex] \tan \angle ABD =\frac{5}{9} [/tex]
[tex] \angle ABD =\tan^{-1}\frac{5}{9} [/tex]
[tex] \angle ABD =29.054604099\degree [/tex]
[tex] \angle ABD =29.05\degree [/tex]
Next, in triangle ABC, by sine rule:
[tex] \frac{\sin \angle ABC}{AC}=\frac{\sin \angle BAC}{BC}[/tex]
[tex] \frac{\sin (\angle ABD+\angle DBC) }{12}=\frac{\sin 90\degree}{15}[/tex]
[tex] \frac{\sin (29.05\degree+x) }{12}=\frac{1}{15}[/tex]
[tex] \sin (29.05\degree+x) =\frac{12}{15}[/tex]
[tex]29.05\degree+x = \sin^{-1}\frac{12}{15}[/tex]
[tex]29.05\degree+x =53.130102354\degree [/tex]
[tex]29.05\degree+x =53.13\degree [/tex]
[tex]x =53.13\degree- 29.05\degree[/tex]
[tex]x =24.08\degree [/tex]
[tex]x \approx 24\degree [/tex]
help pls lol it’s due today:)))
Answer:
4. supplementary
5. complementary
Step-by-step explanation:
4 is supplementary because the sum of the two angles is 180°.
5 is complementary because the sum of the two angles is 90°.
Answer:
4. Supplementary
Supplementary angles sum up to 180 degrees.
105 degrees + 75 degrees = 180 degrees
5. Complementary
Complementary angles sum up to 90 degrees.
30 degrees + 60 degrees = 90 degrees
Hope this helps, thank you !!

Mary and Will rent a tandem bike for $10/hr. Which value is the dependent variable? Which is the independent variable
Answer:
Step-by-step explanation:
In this scenario, the dependant variable would be the total cost of the rental for the bike. This is because the actual cost depends on the number of hours that the individual has decided to rent the bike. The independant variable is the number of hours that they chose to rent the bike since it does not depend on any other factor in the scenario.

Three students have already enrolled for a creative writing class. The teacher will cancel the class if there are fewer than 10 students enrolled. Write three values for numbers of students needed to sign up so that the the creative writing class can be held
Answer:
7, 10 and 15
Step-by-step explanation:
Given
[tex]S_1= 3[/tex] --- Students already enrolled
[tex]Total = 10\ (less)[/tex]
Required
Determine the additional number of students needed for the teacher not to cancel the class
First, we need to calculate the number of students for the teacher to cancel the class.
Represent this with x.
So, we have:
[tex]S_1 + x < Total[/tex]
Make x the subject
[tex]x < Total - S_1[/tex]
Substitute values for Total and S1
[tex]x < 10 - 3[/tex]
[tex]x < 7[/tex]
This means that if less than 7 additional students come to the class, the teacher will cancel the class.
So, for the teacher not to cancel the class, the students must be 7 or greater (i.e. 7, 8, 9, 10....)

Answer:
x= -3/2 or x=1.
Step-by-step explanation:
First, make the equation into a factorable form by subtracting 2 from each side to get 2x²+x-3=0. Then factor that into (2x+3)(x-1)=0. Then, you would do 2x+3=0, 2x=-3, x= -3/2. After that, do the second equation x-1=0, x=1.

8. The diagonal of a computer monitor is measured to be 17 inches. If the width of the monitor is 12 inches, find the
height of the monitor to the nearest inch.
a. 17 inches b. 12 inches
c. 16 inches d. 145 inches
Answer:
b. 12 inchesStep-by-step explanation:
D = 17 in
W = 12 in
H = ??
Monitor is a ractangle, so we can use the Pythagoeran theorem:
W² + H² = D²
12² + H² = 17²
H² = 289 - 144
H² = 145
H = √145 ≈ 12
Find the measure of angle b
Answer:
26˚
Step-by-step explanation:
Since there is already two angles (The square in the corner shows that the angle is 90˚)
So subtract 90˚ with 64˚ which is 26˚
Answer:
this whole angle is equal to 90°
so the value of angle b = 90°-64°
so the value of b= 26.
Pls help me :(
Solve for x
Answer:
x = -3
Step-by-step explanation:
To answer this question, you should first remember that the inside angles of a triangle will always add up to 180 degrees. Therefore, we can make an equation and solve it form there:
55 + 54 + (x + 74) = 180
We add like terms:
109 + (x + 74) = 180
Continue adding like terms:
183 + x = 180
Next, we dubtract to siolate the "x" variable:
x = -3
Hope this helps :)
x=-3
Step-by-step explanation:
To start off, you're going to want to know and understand that all the angles of triangle equal 180 degrees.
Now that we know a triangle equals 180 degrees, lets make an equation. This is equation can be 55+54+74+x=180.
Now, lets combine the like terms in the equation. The equation now becomes 183+x=180.
From here, we subtract 180 from both sides, which would get us x=-3.
To double check that this is correct and that it works, you can plug in the -3 where the x would be.
I hope this helped!! Let me know if you have any further questions.

It costs $2.80 to buy 4 apples. You want to buy 7 apples. How much will that cost?
Answer:
$4.90
Step-by-step explanation:
Answer:
10 dollars
Step-by-step explanation:
4 / 2.80 = 1.42857142857
so that means 1.42857142857 is the cost of one apple.
1.42857142857 x 7 = 10
so your answer is,
it costs $10 for 7 apples.
I Hope this helped!
