Kylie is preparing for the science fair that will take place in six weeks. She has three plants that she has grown from seeds, which she considers to have height 0 centimeters, and she is measuring their heights as she applies different treatments to each. The second plant is receiving Plant Food B. After 3 weeks, it is 10 centimeters tall. If it continues growing at this rate, how tall will it be after 6 weeks?
Answers
The height of plant B growing at a rate of 3.33 centimeters per week should have a height of 19.98 cms.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
First we need two points (x, y) to obtain the slope.
Assuming height to be 'y' and weeks to be 'x'.
Therefore, (0, 0) and (3, 10) are the two points.
Slope(m) = (10 0)/(3 - 0).
Slope(m) = 10/3.
Slope(m) = 3.33
Now, To obtain the y-intercept.
10 = 3(3.33) + b
b = 0.01 Or neglegible.
Therefore y = 3.3x.
Now, In the 6th week, the height of plant B will be,
y = 3.33(6).
y = 19.98 or 20 cm.

-3y-2=7 what is the value of y
Answers
Answer:
y = -3
Step-by-step explanation:
Add 2 to each side to isolate the -3y. Doing this leaves you with -3y=9. You then divide each side leaving you with y = -3
Answer:
The equation has one solution at which y = -3.
Step-by-step explanation:
To find the value of y, we need to isolate it from the rest of the equation.
Add 2 to both sides of the equation.Divide by -3 on both sides of the equation.Simplify the equation if necessary.[tex]\displaystyle{-3y-2=7}\\\\-3y = 9\\\\\bold{y = -3}[/tex]
We can check to make sure that y = -3 by substitution.
[tex]\displaystyle{-3(-3)-2 = 7}\\\\9-2=7\\\\7= 7 \ \checkmark[/tex]
Because we got a true statement, we can determine that y = -3.

jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. which expression can he use to figure out the number of holes he will need to drill
Answers
Answer: 36 / 2 1/4
Step-by-step explanation:
From the question, we are informed that Jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. The expression that he can use to figure out the number of holes he will need to drill will be:
= 36 ÷ 2 1/4
From the expression we can then calculate the number of hours to drill. This will be:
= 36 / 2 1/4
= 36 / 9/4
= 36 × 4/9
= 16
He'll need to drill 16 holes

A watercooler contains 160 cups of water. During practice, each person on a team fills a water bottle with 3 1/3 cups of water from the cooler. How many water bottles can a team fill from a single watercooler?
Answers
Answer: Number of water bottles a team can fill from a single watercooler = 48
Step-by-step explanation:
Given: A watercooler contains 160 cups of water.
Each person on a team fills a water bottle with [tex]3\dfrac13[/tex] cups of water from the cooler.
Here, [tex]3\dfrac13=\dfrac{10}{3}[/tex]
Now , Number of water bottles a team can fill from a single watercooler = [tex]160\div \dfrac {10}3[/tex]
[tex]=160\times\dfrac3{10}\\\\=16\times3=48[/tex]
Hence, Number of water bottles a team can fill from a single watercooler = 48
Number of water bottle IT team can feel a single watercooler =48
The pitch of a roof is the number of feet the roof rises for each 12 feet horizontally. If a roof has a pitch of 8, what is its slope expressed as a positive number?
Answers
Since slope, m, is defined as the rise/run; then m = 8/12. Simplifying, we obtain a slope m = 2/3 In order to write the line of the roof as an equation, let's assume that the roof line starts at the origin (0, 0); it rises 8 units for every 12 it advances; up to the point (12, 8). At this point, the roof descends at the same rate until it reaches the point (0, 24). We need to set two equations with the given constraints: y = mx + b since the roof ascend from (0, 0) up until (8, 12) we use a positive slope: y = 2/3x + b If we use (0, 0) to define b, then the equation of this section of the roof will be:
y = 2/3x 〈0 ≤ x ≥ 12〉 At (12, 8) the roof starts descending at the same rate, then we use the negative slope m = -2/3: y = -2/3x + b Now, let's use (12, 8) to define b: 8 = (-2/3)(12) + b Simplifying, we obtain b = 16, ∴ the equation of this section of the roof will be: y = -2/3x + 16 〈12 ≤ x ≤ 24〉
