Answer:
80 minutes
Step-by-step explanation:
Represent Plan A as y = $26.50 + ($0.35/min)x, where x is the number of minutes consumed.
Represent Plan A as y = $42.50 + ($0.15/min)x
We set these two equations equal to one another and solve for x, the number of minutes at which the costs of the two plans are momentarily equal:
y = $26.50 + ($0.35/min)x = y = $42.50 + ($0.15/min)x
Combining like terms, we get: ($0.20/min)x = $16.00
$16.00
Then x = -------------------- = 80 minutes
($0.20/min)

Law of Cosines : c2 = a2 + b2 - 2ab cos C
Enter
Answer:
[tex]C=69.1^{\circ}[/tex]
Step-by-step explanation:
The Law of Cosines is given as:
[tex]c^2=a^2+b^2-2ab\cos C[/tex].
Plugging in given values, we get:
[tex]16^2=8^2+17^2-2\cdot 8\cdot 17\cdot \cos C,\\\cos C=\frac{-97}{-272},\\C=\arccos(\frac{97}{272}),\\C=\fbox{$69.1^{\circ}$}[/tex].

You call a taxi company to find out their rates. The taxi company charges $1.50 for the first mile, and $.90 for each additional mile. How far could you go for $20 if you give the driver a $2 tip? Write your answer, then write a written explanation of how you got your answer. Explain your steps in complete sentences!
Step-by-step explanation:
(2$+1.5&)+0.9$X=20$
3.5$+0.9$X=20$
0.9$x=20$-3.5$
x=16.5$/.9$
x=18.333
so he can travel 18.333miles.
first we need to add the two separated cause of 1.5 Dollar in $2 tip which give us 3.5 dollar that is to be subtracted from the $20 you have. then the money that is left in your pocket is 16.5 dollar s this will be deducted 0.9 for every mile so dividing 16.5 by 0.9 gives 18.333.

Answer:
a) 96m
b) 2 m/s^2
Step-by-step explanation:
The distance travelled in a velocity time graph as shown in the image is the area of the shape. As such, considering the first 14 seconds, the distance covered will be computed by finding the area of the shape.
Note that the shape to be considered ends t the 14 seconds mark. This shape is a trapezium. The area of a trapezium is given as
A = 1/2(a + b) h
where a and b are the parallel sides of the trapezium and h is the height As such, the distance covered in the first 14 seconds
= 1/2 (14 + 10) * 8
= 4 * 24
= 96m
The acceleration after 4 seconds
Acceleration is the rate of change of velocity with time, at time 0 second, the velocity is also 0 but at time 4 seconds, the velocity is 8 m/s hence, the acceleration after 4 seconds
= 8/4
= 2 m/s^2

6. Determine the Rate of Change in the graph below.
Answer: slope is 1/2
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
Using the equation slope = y2-y1/x2-x1 we can plug in (-4,-6) as x1 and y1 and (6,-1) as x2 and y2. We than have the equation -1+6/6+4 = slope, doing the math we now have 5/10 or 1/2 which is our rate of change

parker was able to pay 56% of his tuition with his scholarship .The remaining $6,057.35 he paid for with a student loan . What was the cost of parkers tuition ?
Answer:
$13,766.70
Step-by-step explanation:
Since he paid 56% with the scholarship, that means $6,057.35 is 44% of the total tuition
To find the total cost of tuition, divide 6,057.35 by 0.44
6,057.35/0.44
= 13766.70
So, the cost of Parker's tuition was $13766.70

Jason makes a fruit salad using only strawberries and blue berries. The ratio of strawberries to blueberries in Jason's fruit salad is 4 cups to 5 cups
Complete question :
Jason makes a fruit salad using only strawberries and blueberries. The ratio of strawberries to blueberries in Jason's fruit salad is 4 cups to 5 cups.
Options is in the attached picture
Which statement describes the contents of Jason's fruit salad?
Answer:
Blueberry makes up 5/9 of the fruit salad
Step-by-step explanation:
Ratio of strawberries to blue berries is 4cups to 5 cups
Hence, in a fruit salad makeup ;
We can say we have 4 cups of strawberry for every 5 cups of blue berry
Fraction of strawberry and blueberries :
Total ratio = (4 + 5) = 9
Fraction of strawberry = 4/ 9
Fraction of blueberry = 5/9
Hence, from the option , the statement ;
Blueberry makes up 5/9 of the fruit salad is true since both are the only ingredients used

3(x + 2) = 2x + 14
How many solutions
Answer:
I solution; x=8
Step-by-step explanation:
You have to solve for x by simplifying both sides of the equation and then isolating the variable
3(x+2)= 2x+14
Distributive Property
3x+6=2x+14
Isolate the variable
3x+6-6=2x+14-6 which is 3x=2x+8
3x-2x=2x-2x+8
x=8

does 3/7 , 12/21 make a proportion
Answer:
No, it does not.
Step-by-step explanation:
The question, does 3/7 and 12/21 make a proportion, does not. It does not make a proportion, because for 3 to equal 12, you must multiply by four. when you multiply 7 by 4, you get 28. that is not right. if this explanation is too confusing, i added a picture
