Answer: I'm pretty sure it's 40 minutes
Step-by-step explanation:
2 hours is 120 minutes and if one subject takes double the time of the other than you basically just have to divide 120 by three. I hope you get what I'm saying cause I'm bad at explaining.
Answer:
40 minutes (or 2/3 hours.)
Step-by-step explanation:
Let the no. of hours the student spend on English be t.
Since math takes twice as long as English, the no. of hours the student takes on math will be 2t.
With the information, we can write this equation:
t + 2t ≤ 2
(≤ symbol is used because the maximum time spent is 2 hours, meaning the student can spend any no. of hours between 0 and 2, including 2 hours exactly.)
Solve the equation like usual (you can take the ≤ sign like =)
t + 2t ≤ 2
3t ≤ 2
t ≤ 2/3 (or 0.666666... hours)
So the maximum amount of time is 2/3 hours.
Multiply 2/3 by 60 to get the time in minutes
2/3 x 60
= 40minutes
So the answer is 40 minutes or 2/3 hours.
A line is perpendicular to y = {2/3x + 2/3}
and intersects the point (-2, 4).
What is the equation of this
perpendicular line?
y = - x + [?]
Answer: y = (-3x/2) + 1
Step-by-step explanation:
From the standard equation y = mx + c, the slope of the equation is 2/3. Therefor slope of a line perpendicular to it will be -3/2.
Hence the equation will be
y = (-3x/2) + c
As this line passes through (-2,4), putting these values in this equation gives c = 1.
Hence the answer is y = (-3x/2) + 1

Stu Dent received scores of 85, 78, and 81 on his first 3 exams in Algebra 1. What is the lowest score does Stu has to get on his 4th exam, so his test average would be at least an 84?
Answer:
92
Step-by-step explanation:
Given
Scores: 85, 78, 81
Required
Determine the least score in 4th subject is average must be at least 84
To solve this, we'll make use of Mean formula.
Mean = Sum of observations/Number of observations
We have that; Average = 84
Number of subjects = 4
Let the 4th subject be represented by F;
So, the sum of the four Subjects is:
Sum = 85 + 78 + 81 + F
Sum = 244 + F
Substitute these values in the above formula.
84 = ¼(244 + F)
Multiply both sides by 4
4 * 84 = 4 * ¼(244 + F)
336 = 244 + F
Subtract 244 from both sides
336 - 244 = 244 - 244 + F
92 = F
F = 92
To have an average of at least 84, Su's score must be atleast 92

Answer:
i) Area of the ring = 462cm²
ii) Perimeter of the ring = 132cm
A complete question related to this found at brainly (ID: 19152996) is stated below:
Calculate the area and perimeter of the following ring where a = 7cm, b = 14cm (i) Area of Ring (ii) The perimeter of Ring
Find attached the diagram.
Step-by-step explanation:
a= smaller radius = 7cm
b= bigger radius = 14cm
i) Area of the ring = Area of larger circle - Area of smaller circle
Area of circle = Area of a ring = πr²
π =22/7
Area of larger circle = (22/7)(14)² = 22×28
Area of larger circle = 616cm²
Area of smaller circle = (22/7)(7)² = 22×7
Area of smaller circle = 154cm²
Area of the ring = 616 - 154 = 462cm²
ii) Perimeter of ring = Perimeter of larger circle + Perimeter of smaller circle
Perimeter of circle = 2πr
When r = 7cm and π = 22/7
Perimeter of smaller circle = 2×(22/7)×7 = 2×22
Perimeter of smaller circle = 44cm
When r = 14cm and π = 22/7
Perimeter of larger circle = 2×(22/7)×14 = 4×22
Perimeter of larger circle = 88cm
Perimeter of ring = 88+44 = 132cm

Simplify: (3x2 − 8xy + y2) − (7x2 − 4xy − 5y2)
Answer:
[tex]-4x^{2} -4xy+6y^{2}[/tex]
Step-by-step explanation:
(3x2 − 8xy + y2) − (7x2 − 4xy − 5y2)
First, we remove the parenthesses. We can just remove the first parnthesses because there isn't any sign before them. When removing the second ones, we will change the sign of every term in it. It becomes:
[tex]3x^{2} -8xy+y^{2} -7x^{2} +4xy+5y^{2}[/tex]
Now we will combine the like terms. That means that we will subtract 7x2 from 3x2, add 4x to -8x etc.
[tex]-4x^{2} -4xy+6y^{2}[/tex]
Answer:
-4xy - 8x + 12y
The pro shop at the Live Oak Country Club ordered two brands of golf balls. Par One balls cost $2.00 each and the Pro Sport balls cost $0.90 each. The total cost of Par One balls exceeded the total cost of the Pro Sport balls by $660.00. If an equal number of each brand was ordered, how many dozens of each brand were ordered?
Answer:
If an equal number of each brand was ordered, how many dozens of each brand were ordered?
50 dozens of each brandStep-by-step explanation:
in order to determine the number of balls purchased, we must first determine the difference in price between them = $2 - $0.90 = $1.10
since the total difference in price was $660 and an equal number of balls were purchased, then the number of balls purchased = $660 / $1.10 = 600 balls
to determine the number of dozens purchased of each brand we just divide 600 by 12 = 50 dozens
Vikas is the head of student council this year at his high school in London. He is responsible for planning the annual graduation trip to Canada's Wonderland. The students will spend one full day at the park and return late that evening. The school has rented a bus for transportation. The entry fee into the park is $50 and the bus costs $600. Write an equation to relate the cost, C, in dollars to the number of student, s, who participate in this fun trip.
Answer:
C = 600 + 50s
Step-by-step explanation:
Let s be the number of students that go on the trip.
Let C be the cost.
The bus costs $600 and the entry fee (for each student) costs $50.
The cost for the trip will be the sum of the cost of the bus and the ticket for every student that goes on the trip.
This implies that the total cost for the trip will be:
C = 600 + 50(s)
C = 600 + 50s

Column 2 is labeled y with entries negative 20, negative 19, negative 18, negative 17.
Answer:
Option C.
Step-by-step explanation:
In a linear function, the change in y-values with respect to x-values is constant.
We need to find table from the given tables which represents a non-linear function.
In option A, x is increasing by 1 unit and y is decreasing by 1 unit. So, rate of change is constant.
In option B, x is increasing by 1 unit and y is decreasing by 1 unit. So, rate of change is constant.
In option C, x is increasing by 1 unit but y is not decreasing by same units. So, rate of change is not constant.
In option D, x is increasing by 1 unit and y is increasing by 1 unit. So, rate of change is constant.
Only in option C, the rate of change is not constant. So, it represents a non-linear function.
Therefore, the correct option is C.

y= -3/4x+8
y=-3/4x+6
y=4/3x-8
y=4/3x-6
Answer:
y = 4/3x - 8
Step-by-step explanation:
slope of given line is -3/4 so the perpendicular slope is 4/3
line goes through (6, 0)
y = mx + b

-8 = b
y = 4/3x - 8
Which graph passes through the point (-5,-6) and has a slope of 2/3 (two over three)
Answer:
Answer A
Step-by-step explanation:
Firstly, you can eliminate the last two choices because they don't go through the point (-5, -6). For slope, use your [tex]\frac{rise}{run}[/tex]. Go up 2 and go left 3, and you'll see that the 1st graph matches this pattern.

Answer:
The initial value of the computer
Explanation:
The v-intercept of the line is the point when the graph goes through the v-axis. At this point, t=0, meaning no time has yet passed. Since no time has passed, the v equals the original value of the computer at the v-intercept, meaning the answer is the initial value of the computer.
