Answer:
30 quizzes
Step-by-step explanation:
12 quizzes in 2 weeks means that there were 6 per week and 6 (quizzes per week) times 5 (number of weeks) would be 30.
Hope this helped!!
Answer:
30, or 42
Step-by-step explanation:
If they took 12 quizzes over the course of 2 weeks, then we can assume that they take 6 quizzes each week (12/2 = 6).
Over the course of 5 weeks, they'll have taken 30 quizzes if the above is true. However, the 'or' is there because I don't know if they're including the past 12 or not. If they are including the 12 quizzes taken over 2 weeks, then the answer is 42. If they are only referring to the 5 weeks of school, then the answer is 30.

Solve the following system by using substitution:
x = -3y - 17
2x + 3y = -7
Answer:
x=10 and y=−9
Step-by-step explanation:
Answer:
(x,y) = (10,-9)
Step-by-step explanation:
x=-3y-17
2x+3y=-7
2(-3y-17)+3y=-7
y=-9
x=-3(-9)-17
x=10

Rampy Ronald is fixing to make a jump with his dirt bike across an 80-foot ravine full of lava. The ramp he’s going to hit to make the jump is 15 feet long, forms a 30° with the ground and ends 5 feet from the edge of the ravine. That said, if he hits the ramp at his bike’s full speed of 60mph, he’ll reach a maximum height of 30 feet.
6. From the start of the ramp to when he reaches his maximum height, how far will Rampy Ronald have traveled horizontally?
7. Is Rampy Ronald going to make the jump, or is he fixing to land in the ravine of lava and become Roasty Ronald? Give geometric constructions backed by mathematics to support your reasoning!!!
Answer:
6. The distance Rampy Ronald would have travelled horizontally is approximately 48.428 feet for an actual maximum height of 21.486 feet
7. Rampy Ronald is going to make the jump
Please find attached the graph of the motion of Rampy Ronald, created with Microsoft Excel
Step-by-step explanation:
6. The given parameters are;
The width of the ravine = 80 ft
The inclination of the ramp with which Rampy Ronald will jump = 30°
The distance from the edge of the ravine the ramp ends = 5 feet
The speed with which Rampy Ronald will make the jump = 60 mph
The maximum height he will reach = 30 feet
Therefore, we have;
The height of the end of the ramp = 15 × sin(30°) = 7.5
The height of the end of the ramp = 7.5 feet
The height of the jump = 30 - 7.5 = 22.5
The vertical velocity = 60 × sin(30°) = 30
The vertical velocity = 30 mph
The horizontal velocity = 60 × cos(30°) = 30·√3
The horizontal velocity = 30·√3 mph
From the kinematic equation, v² = u² - 2gh, we have;
u² = 2gh
h = u²/2g = 900/(2 × 32.17405) ≈ 13.986
The maximum height reached 13.986 + 7.5 = 21.486
From v = u - gt
t = u/g = 30/32.17405 ≈ 0.932
t ≈ 0.932 s
The distance Rampy Ronald would have travelled horizontally = 30·√3 × 0.932 ≈ 48.428
The distance Rampy Ronald would have travelled horizontally ≈ 48.428 feet
7. The time before Rampy Ronald reaches ground level again, is given by the following relation;
h = 1/2·g·t²
21.846 = 1/2 × 32.17405 × t²
t = √(21.846/16.087025) ≈ 1.165
t ≈ 1.366 s
The horizontal distance traveled is therefore;
The horizontal distance traveled from maximum height is 30·√3 × 1.165 ≈ 60.535
The horizontal distance traveled from maximum height is ≈ 70.979 feet
The total horizontal distance traveled ≈ 48.428 + 60.535 = 108.963
The total horizontal distance traveled ≈ 108.963 feet
The total horizontal distance required to make it across the ravine = 5 feet + 80 feet = 85 feet
Therefore, Rampy Ronald is going to make the jump

At an aunt's wedding , Nicolas collected data about an ice sculpture that was about to completely melt . A graph of his data is shown at right . a . Write an equation for a line of best fit . What are the units for the slope and y-intercept in the equation ? b Based on your equation , how tall was the ice sculpture one hour before Nicolas started measuring ?
Answer:
Step-by-step explanation:
From the scatter plot given in the attachment,
a). Line of best fit will pass through two points (0, 10) and (4, 0)
Let the equation of the line is,
y = mx + b
m = slope of the line
b = y-intercept
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{10-0}{0-4}[/tex]
m = -2.5 inches per hour
y-intercept = 10 inches
Therefore, equation of the line will be, y = -2.5x + 10
b). Since, Nicolas started measuring the height of the ice sculpture at x = 0
One hour before the start of the observations means x = (0 - 1) = -1
From the given equation,
y = -2.5(-1) + 10
= 2.5 + 10
= 12.5 inch

position to term rule of 2, 6, 10, 14, 18
multiply by _____ and subtract by _____
Answer:
Please check the explanation.
Step-by-step explanation:
Given the sequence
2, 6, 10, 14, 18
An arithmetic sequence has a constant difference and is defined as
[tex]\:a_n=a_1+\left(n-1\right)d[/tex]
compute the differences of all the adjacent terms
[tex]6-2=4,\:\quad \:10-6=4,\:\quad \:14-10=4,\:\quad \:18-14=4[/tex]
The difference between all the adjacent terms is the same.
Thus,
[tex]d=4[/tex]
and
[tex]a_1=2[/tex]
Therefore, the nth term is computed by:
[tex]a_n=4\left(n-1\right)+2[/tex]
[tex]a_n=4n-2[/tex]
Thus, position to term rule of 2, 6, 10, 14, 18 multiply by __4___ and subtract by __2__.

Each week, high school students can collect a maximum of 347 cans of food for the town food pantry. What is the maximum number of cans that the high school students can collect in 35 weeks?
10,410 cans
10,415 cans
12,145 cans
12,245 cans
Answer:
12,145
Step-by-step explanation:
If 347 cans is the max PER week, and they have 35 weeks, then all we need to do is multiply 347 times 35.
347*35 = 12,145
The max amount of cans they can collect in 35 weeks is 12,145 cans.
Answer: 12,145

Answer:
5 1/6 ÷ 4 2/3 = 31/28
3 3/4 ÷ 1 2/8 = 3
4 2/4 ÷ 2 1/4 = 2
5 2/5 ÷ 1 4/5 = 3
4 2/8 ÷ 3 2/4 = 17/4
3 3/9 ÷ 2 4/12 = 10/7
7 1/2 ÷ 3 3/5 = 25/12
6 2/8 ÷ 3 1/3 = 15/8
Explanation:
5 1/6 ÷ 4 2/3 = 31/6 ÷ 14/3 = (31/14) / (6/3) = (31/14) / 2 [when you divide by a certain number you multiply that number by the denominator] = 31/28
5 1/6 ÷ 4 2/3 = 31/6 ÷ 14/3 = 31/6 × 3/14
