at every 30 minutes, a third of the popcorn is consumed.
After an hour, 1/3 + 1/3 = 2/3 of popcorn would be consumed.
At one hour 30 minutes, 2/3 + 1/3 = 3/3 or 1 or all of the popcorn would have been consumed
Step-by-step explanation:
The rate at which popcorn is consumed is 1/3 in 30 minutes
so, in 1 and a half hours, all the popcorn would be finished
1/3 + 1/3 + 1/3 = 1

hey! can u help me with this?! 6 divided by 3/5 in fraction form!?!?!!?
Answer:
10/1
Step-by-step explanation:
You do
6÷ 3/5
Flip the 3/5 then multiply
6 ° 5/3
Reduce the numbers with the greatest common factor 3
So 2•5
And that's 10
Ans is 10.
The numbers in 6 divided by 3/5 are labeled below:
6 = whole number
3 = numerator
5 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
6 x 5/3 = 30/3
Thus, the answer to 6 divided by 3/5 in fraction form is:
30/3
To make the answer to 6 divided by 3/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
30 / 3 = 10
The answer is rounded to the nearest two decimal points if necessary.
30/3 can be simplified to 10/1.
10/1 is an improper fraction and should be written as 10.
Helen needs 60 g of sugar to make 15 biscuits.
She also needs
three times as much flour as sugar
two times as much butter as sugar
Helen is going to make 60 biscuits.
a) Work out the amount of flour she needs.
Answer:
60 grams sugar for 15 biscuits.
3x60 grams of flour, so 180 grams for 15 biscuits.
60÷15= 4 batches.
4 batches with 180 grams each- 4 x 180= 720 grams of flour.

A submarine was in a resting position 400 m below sea level. It rose 225 m. Determine its new depth?
Answer:
175 meters, since its below sea level it would be- -400m - (-225m), subtracting with negative # and negative # is the equivalent of getting closer to zero, just figure out 400 - 225, and put a - symbol at the beginning of the number

You just looked at the graph of this system of equations. Why will the lines never intercept?
y=-x+5
y=-x-3
Answer:
Step-by-step explanation:
The have the same slope, -1, but different y-intercepts. The lines are parallel.
Answer:
The linear equations have the same slope, so the rate of change for each is the same. As long as the rate of change is the same, the lines will stay the same distance apart and not intersect.

A rectangle is a square? True or False
Answer:
False
A square is a quadrilateral with four right angles, two sets of parallel lines, and equal sides.
A rectangle is not equilateral, so it is not a square. Squares are rectangles, actually.
So, False
Hope that helps!
Step-by-step explanation:
Answer:
False, but can be true
Step-by-step explanation:
Rule for being a square.
1. All sides have to be congruent in length
2. Must have all 90°
3. has 4 sides and 4 angles (has to be a quadrilateral)
4. 2 pairs of parallel lines
A rectangle is not a square directly. It does not have congruent sides. Although, this means that a square is a specialized case of the rectangle. It will only be a square if all sides are congruent.
Hey guys!
Can someone please tell me how to factor linear expressions I need it ASAP
Answer:
I can.
Step-by-step explanation:
Answer:
To factorise an expression means to 'put into brackets' by taking out common factors. When factorising, always take the largest factors possible out of the expression.
Example 1 - Factorising simple linear expressions
a) Factorise: 3x+93x+9.
Notice 3 is both a factor of 3x3x and 99. We can factorise the expression by taking the 33 outside of the brackets.
3x+9=3(x+3)3x+9=3(x+3).
Hope it helps!!!

Answer:
1. The length of a necklace that you make at a rate of 10 cm per hour without taking a break.
Step-by-step explanation:
Okay so lets think about this by first looking at the graph we are given.
Whatever is going on, its going up, and steadily. There's no points were the line goes down or curves, right? So it's constant and forward. So now let's look at the possible answers.
1. The length of a necklace that you make at a rate of 10 cm per hour without taking a break.
Is is constant? Yes, the rate is 10 cm/hr. Does it stop? No, you don't take a break. Is it forward? Yes, you are making more of the necklace, not less.
Thinking of the y-axis as amount of necklace made, and x-axis as time spent, this is the right graph.
So this is your answer!! Just to be sure, let's look at the other possible answers.
2. The height of a balloon as it rises, gets caught in a tree, then continues to rise.
This is not constant, because it gets stuck and stops. But it is forward, because it is rising.
Thinking of the y-axis as the height of the balloon, and x-axis as time passed, this is NOT the right graph.
This is not the answer.
3. The total distance you are from home if you ride your bike three mi/hr for 1 hour, then stop for a rest.
It is not constant, because you stop and take a break. But it is forward, because you are moving forward.
Thinking of the y-axis as the speed or distance from home, and x-axis as time passed, this is NOT the right graph.
This is not the answer.
4. The volume of water in a bath tub as it is draining.
This one IS constant, but in the wrong direction. The tub is draining, not filling, so the amount is decreasing. This would be the correct graph, if the slope were negative and the line was like this \ and not like this /.
Thinking of the y-axis as the amount of water in the tub, and x-axis as time passed, this is NOT the right graph.
This is not the right answer.
These leave us with the first answer as being correct.
Ms lebea, is a grade 10 mathematical literacy teacher at nkami high school gave learners a test out of 70 marks. She has 60 learners in her class and 35 are girls..

Line AB contains points A (8, −4) and B (1, −5). The slope of line AB is (5 points) Group of answer choices −7 negative 1 over 7 1 over 7 7
Answer:
1/7
Step-by-step explanation:
Given that :
Line AB contains points A (8, −4) and B (1, −5)
Slope = Rise / Run
Rise = y2 - y1 = - 5 - (-4) = - 5 + 4 = - 1
Run = x2 - x1 = 1 - 8 = - 7
Slope = Rise / Run = - 1 / - 7
Slope = 1/7
