Answer: 3.75
Step-by-step explanation:
The following can be gotten from the question:
Time taken for each session = 4/5 hours
Total time set aside by principal = 3 hours
The number of sessions that can be sheduled for each student will be:
= Total time set aside by principal / time taken for each session
= 3 hours / 4/5 hours
= 3 × 5/4
= 3.75
solve 9 - c = 17d for c
Answer:
c = 9 - 17d
Step-by-step explanation:
9-c = 17d
9-c+c= 17d + c (add c to both sides)
9 = 17d + c (Simplify)
9 - 17d = 17d - 17d + c (subtract 17d from both sides)
9 - 17d = c (Simplify)
The equation can be solved for c as c = 9 - 17d.
How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
The given equation is 9 - c = 17d.
It can be solved in terms of c as follows,
9 - c = 17d
Subtract 9 from both sides to get,
9 - c - 9 = 17d - 9
=> -c = 17d - 9
Multiply both sides by -1 to get,
-1 × -c = (17d - 9) × -1
=> c = 9 - 17d
Hence, the given equation can be written in terms of c as c = 9 - 17d.

Q1) f(x) = 2x^2 - 5x, g(x) 3x^2 find f(2)
Answer:
f(2)= -2
g(2)= 12
Step-by-step explanation:
To solve this we use the substitution method. Since f(2) is your variable, we will plug the x-value of 2 into each equation
f(2)= 2(2)^2-5(2)
f(2)=8-10
f(2)= -2
If the same variable is used for both equations then g(x) would be g(2) as well leaving you with
g(x) = 3x^2
g(2)= 3(2)^2
g(2)=12

x = – 4y + 6
2x + 9y = 16
Step-by-step explanation:
x = -4y + 6
Now,
Substituting the value of x on 2x + 9y = 16, we get -.
2(-4y + 6) + 9y = 16
-8y + 12 + 9y = 16
y = 16 - 12
y = 4Now,
Substituting the value of y on 2x + 9y = 16, we get -
2x + 9(4) = 16
2x = 16 - 36
2x = -20
x = -10Hence,
The value of x is -10 and y is 4.

The angles of a triangle are in the ratio 1 : 4 : 5.
Work out the size of the smallest angle?
Answer:
18°
Step-by-step explanation:
sum the parts of the ratio, 1 + 4 + 5 = 10 parts
The sum of the 3 angles in a triangle = 180° , then
180° ÷ 10 = 18° ← value of 1 part of the ratio
Since 1 is the smallest part of the ratio it represents the smallest angle, thus
smallest angle = 18°

The value of y varies directly with the value of x. If x = 8 then y = 320. What is the value
of x when y = 52?
Answer:
1.3
Step-by-step explanation:
I believe this is correct because if you divided 320 by 52 you get 6.15384615385 (or just 6.1) and since we did it to the Y operation we do it to the X operation and x, aka 8, divided by 6.1 equals 1.3.

Jamilia has a weather station in her backyard. She uses a rain gauge to track the total rainfall during two storms.
1: Jamilia graphs the function describing mondays rainfall. Is the graph linear or nonlinear? How do you know?
2: what is the real-world meaning of the slope of the graph?
3: Next, Jamilia graphs the function describing Thursday’s rainfall. Is this graph linear or nonlinear? How do you know?
4: What does the y-intercept of the graph or Monday’s storm mean? Does the y-intercept of the graph of Thursday’s storm have the same meaning?
Answer:
1. The graph is linear because the precipitation increases at a steady rate of 3 mm every 15 minutes, or 0.2 mm per minute.
2.The slope of a line tells us how something changes over time, if the slope is found, the rate of change can be found. In this case it is telling us how the rain increases over time.
3.The graph is nonlinear. Because the rainfall total does not change at a constant rate, the points do not form a line.
4.The y intercept means the total rain that was present at the start of her recording, this means there was no rain when she first started her experiment.
Step-by-step explanation:
A linear function is such that has a constant rate, while a nonlinear function does not have a constant rate.
1. Monday rainfall
From the table that represents Monday rainfall, we have the following observations
As the time increases, the precipitation increases at constant interval.Time increases constantly by 15 minutes, precipitation increases constantly by 3 mmThis means that, the graph is a linear graph.
2. The slope
The slope in this case, is the amount of precipitation in one minute
3. Thursday rainfallFrom the table that represents Thursday rainfall, we have the following observations
As the time increases, the precipitation increasesTime and precipitation do not increase constantlyThis means that, the graph is a nonlinear graph.
4. The y-intercept
This is the value of precipitation when the time is 0
From the table,
The precipitation at 0 minute is 0
Hence, the y-intercept, is 0
And yes, both graphs have the same y-intercept

A baseball camp is held at a complex that has 6 baseball diamonds. The coaches would like each diamond to have the same number of campers. Use divisibility rules to determine whether this is possible if 152 kids show up for the camp.
Answer:
Using divisibility rules, it is impossible to have exactly the same number of kids in each of the diamonds
Step-by-step explanation:
Here, we want to use divisibility rule to check for the possibility of 152 kids showing for the kids
Since we need exactly equal number of kids in each of the diamonds, we are going to test the possibilities that we can share 152 to have the same number of campers in each of the diamond
Mathematically 152/6 = 25.3333
Since we have a remainder for the division, it is impossible to share the campers equally in the six diamonds if 152 kids show up for the camp

There are two gardens, garden A and garden B are shown in the image below.
Is there more than one expression that can be used to represent the perimeter of each garden?
Step-by-step explanation:
garden a:
perimeter=2xlength+2xwidth = 2x(5x(2x-3))+2x(2x-3) = 20x-30 + 4x-6 = 24x-36 / 12(2x-3) feet
garden b:
perimeter= 5x+5 + 4x+2 + 8x-8 = 17x - 1 feet
Answer:
Perimeter A = 24x - 36Perimeter B = 17x - 1Step-by-step explanation:
garden A
Width (W) = 2x - 3
Length (L) = 5(W)
= 5 (2x - 3)
= 10x - 15
Perimeter A = 2L + 2W (perimeter of a rectangular garden)
= 2(10x - 15) + 2(2x - 3)
= 20x - 30 + 4x - 6
= 24x - 36
garden B
side 1 = 5x + 5
side 2 = 4x + 2
side 3 = 8x - 8
Perimeter B = sides (1 + 2 + 3)
= 5x+5 + 4x+2 + 8x-8
= 5x + 4x + 8x + 5 + 2 - 8
= 17x - 1

Brandon bought a baseball on for $15.00. He had a coupon for a 20% discount. How much did Brandon pay for the baseball?
A. $3.00
B. $0.30
C. $12.00
D. $15.00
Answer:
Brandon paid $12.00.
Step-by-step explanation:
To solve, you simply must multiply 15 by 0.8. You multiply by 0.8 and not 0.2 because you are calculating 80% of the original cost, which is the same thing as 20% off.
15 x 0.8 = 12

20 – 3n > 7n show work
Answer:
n>5
Step-by-step explanation:
move the 20 onto the other side of the > by subtracting 20 on the left side and adding 20 on the right side
now you have
-3n>7n-20
move the 7n onto the other side the same way. subtract 7n from one side and add it to -3n. now you have
4n>20
this is called adding similar terms or inverse operations what ever you wanna call it. Now you divide N by 4. This is because 4n can be simplified to 4×N and the opposite of multiplication is division. you do the same on the other side.
n/4>20/4.
you are left with n>5
Answer:
n<2
Step-by-step explanation:
Subtract 20 from both sides 20-3n-20>7n-20
Simplify -3n>7n-20
Subtract 7n from both sides -3n-7n>7n-20-7n
Simplify again -10n>-20
multiply both sides by -1 (-10n)(-1) < (-20)(-1)
Simplify 10n<20
Divide both sides by 10 Then you get your answer
