At that point, there would be 417 cookies left. At that rate it would take about 31 minutes.
The mass of substances left in a sample

This question tests one's knowledge of states of matter. Kim would have to classify the water as gaseous matter in this case.
Why should Kim classify the water as gaseous?Remember, she boiled all the liquid away. Hence in their evaporated state, the water now assumes a gaseous form.

3. Write an equation to represent the situation:
A taxi ride costs $6.50 total. The fare was
charged at $1.25 per mile., How many miles did the
taxi travel?
Answer:
Equation would be 1.25m = 6.50.
The taxi traveld 5.2 miles.
Step-by-step explanation:
So we know that they charge 1.25 per mile but we dont know how many miles they traveld.
Our total cost was 6.50. This is imediatly enough information to help build an equation.
Since the amount of the miles travels is unkown, we leave it as "m" but we know it cost 1.25 per mile therfore it makes it 1.25m
Next we do, 1.25m = 6.50 since 6.50 was our total cost.
Now, we solve it! We solve it by simply dividing 1.25 on both sides:
[tex]\frac{1.25m}{1.25}[/tex] = [tex]\frac{6.50}{1.25}[/tex]
When we divide 1.25 by 1.25 we get 1 which leaves it at 0. When we divide 6.50 by 1.25 we get 5.2.
m = 5.2
miles = 5.2
A group of tourists travels 4 hours by car and 7 hours by train. In this time, they go a total of 640 km. What is the speed of the train, if it is 5 km greater than the speed of
the car?
The speed of the train is given by T = 60 km/hr
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let's call the speed of the car "x" (in km/h).
And the speed of the train is "x+5" (also in km/h).
We can use the formula:
distance = speed x time
To write two equations, one for the distance traveled by the car and one for the distance traveled by the train:
The distance traveled by car C = x × 4
The distance traveled by train T = (x+5) × 7
We know that the total distance traveled is 640 km, so we can write:
x × 4 + (x+5) × 7 = 640
Expanding the brackets and simplifying, we get:
4x + 7x + 35 = 640
11x = 605
x = 55
So the speed of the car is 55 km/h. Using this, we can find the speed of the train:
The speed of train T = speed of car C + 5
The speed of train = 55 + 5
The speed of train = 60 km/h
Hence , the speed of the train is 60 km/hr

work out 9 over 13 of 182 (9 over 13 is supposed to be a fraction)
Answer:
126
Step-by-step explanation:
In math, "of" usually means multiplication.
9/13 of 182 means 9/13 × 182.
9/13 × 182 = 9/13 × 182/1 = (9 × 182)/(13 × 1) = 1638/13 = 126
Answer: 126
Answer:
126
Step-by-step explanation:
To find 9/13 of 182, we would divide 182 by 13 and multiply the quotient by 9.
182 ÷ 13 = 14
14 • 9 = 126
To double-check our answer, we can divide 126 by 182 and see if the fraction is congruent to 9/13.
126 ÷ 182 = 0.6923
9 ÷ 13 = 0.6923

a. What is a quadratic equation in factored
form that models the situation?
Launching the fuse is an illustration of a quadratic model, and the equation of the quadratic model is f(x) = 15(x - 3)(x - 8)
How to model the quadratic equation?From the complete question, the zeros of the quadratic function are:
x = 3 and x = 8
Rewrite as:
x - 3 = 0 and x - 8 = 0
So, the quadratic equation is:
f(x) = a(x - 3)(x - 8)
Also from the graph, we have the following point
(x,y) = (4,60)
Substitute 4 for x and 60 for f(x) in the function
a(4 - 3)(4 - 8) = 60
Evaluate the difference
a(1)(-4) = 60
Evaluate the product
-4a = 60
Divide both sides by 4
a = -15
Substitute a = -15 in f(x) = a(x - 3)(x - 8)
f(x) = -15(x - 3)(x - 8)
Hence, the equation of the quadratic model is f(x) = 15(x - 3)(x - 8)

If the volume of a prism is 30m3 and it’s height is 5m what is the area of the base
Answer:
6[tex]m^{2}[/tex]
Step-by-step explanation:
Any prism volume is V = BH where B is area of base and H is height of prism,
B = 1/2 h(b1+b2) since B is the area of the base
[tex]\frac{v}{h}[/tex]=B if we solve for B from the volume formula
which gives: [tex]\frac{30m^{3} }{5m}[/tex] and the units cancel out to leave 6[tex]m^{2}[/tex] is the area of the base
