Find the smallest number which is exactly divisible
by 15 20 and 30
Answer:
60
Step-by-step explanation:
The smallest number that is divisible by 15, 20 , and 30, must have the needed factors of each of these numbers:
15 = 3 * 5
20 = 2 * 2 * 5
30 = 2 * 3 * 5
Then the minimum common factor must have the following factors to satisfy the divisibility of all of the numbers above:
2 * 2 * 3 * 5 = 60
The rate of change of y with respect to x is proportional to y2. Write a differential equation for the statement. (Use k for the constant of proportionality.)
Answer:
[tex]\dfrac{dy}{dx}\ = ky_2[/tex]
Step-by-step explanation:
The rate of change of y with respect to x is expressed as shown;
[tex]\dfrac{dy}{dx}[/tex]
If the rate of change of y with respect to x is proportional to y2, this is expressed as;
[tex]\dfrac{dy}{dx}\ \alpha \ y_2[/tex]
If we remove the proportionality sign, a proportionality constant will be introduced as shown;
[tex]\dfrac{dy}{dx}\ = ky_2[/tex]
where k is the constant of proportionality.
Hence the differential equation for the statement is expressed as [tex]\dfrac{dy}{dx}\ = ky_2[/tex]
When a rate is simplifed so that it has a denominator of 1 unit, it is called a(n) ___________ rate.
Answer:
called unit rate .

Andre rode his bike at a constant speed. He rode 1 mile in 5 minutes. Which of these equations represents the amount of time t (in minutes) that it takes him to ride a distance of d miles?
Answer:
5minutes and the the distance is 1miles
Answer:
t=5d
Step-by-step explanation:
Given that Andre rode his bike at a constant speed.
Number of miles driven = 1 mile
Time taken to drive 1 mile = 5 minutes.
Then speed can be calculated using formula:
Speed = Distance / Time
Now we have to find the amount of time t (in minutes) taken by him to right distance d so we can again use same formula.
Speed = Distance / Time
or
Time = Distance / Speed
Plug the given values
t = 5d
Hence find answer will be equation t=5d.

See the explanation for a 'tip'
Explanation:
Quotient means 'the answer after dividing'.
If you get really stuck this is one (bit long) way of dealing with it.
Firstly lets for the moment forget about the negative and just deal with
-96÷12
Write as 96 12
Notice that both numbers are even so we can divide by 2
96÷2=48
12÷2=6
Again they are both even
48÷2=24
6÷2=3
The two digits of 24 are such that
2+4=6
and 6 is exactly divisible by 3 so 24 is also exactly divisible by 3. So now we can do this:
24÷3=8
3÷3=1
Now we put the negative back in giving −8

Since sqrt(90) is an irrational number, by definition it cannot be represented as a ratio of two integers.
The school Library was building a new one-room addition. the architects drawing shown below uses the scale 1/8 in = 1ft
Dimensions: 2 1/4 and 3 3/16
Using the dimensions indicated on the drawing, what is the total area of the new room?
Answer:
the total are is 459
Step-by-step explanation:
3 3/16 divided by 1/8 = 25 1/2 or 25.5
2 1/4 divided by 1/8 = 18
so 18 x 25.5 = 459

What is the scale factor?The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.
WE are given that school Library was building a new one-room addition. the architects drawing shown below uses the scale 1/8 in = 1ft
Dimensions: 2 1/4 and 3 3/16
Therefore,
3 3/16 divided by 1/8 = 51/2 or 25.5
2 1/4 divided by 1/8 = 18
Thus we have the area
= 18 x 25.5
Area = 459

Write an equation in standard form for the line, where the points (-2, -1) and (0, 4) are on the line
Answer:
An equation in standard form for the line is:
[tex]\frac{5}{2}x-y=-4[/tex]
Step-by-step explanation:
Given the points
(-2, -1) and (0, 4)The slope between two points
[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:4\right)[/tex]
[tex]m=\frac{4-\left(-1\right)}{0-\left(-2\right)}[/tex]
[tex]m=\frac{5}{2}[/tex]
Writing the equation in point-slope form
As the point-slope form of the line equation is defined by
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Putting the point (-2, -1) and the slope m=1 in the line equation
[tex]y-\left(-1\right)=\frac{5}{2}\left(x-\left(-2\right)\right)[/tex]
[tex]y+1=\frac{5}{2}\left(x+2\right)[/tex]
[tex]y=\frac{5}{2}x+4[/tex]
Writing the equation in the standard form form
As we know that the equation in the standard form is
[tex]Ax+By=C[/tex]
where x and y are variables and A, B and C are constants
so
[tex]y=\frac{5}{2}x+4[/tex]
[tex]\frac{5}{2}x-y=-4[/tex]
Therefore, an equation in standard form for the line is:
[tex]\frac{5}{2}x-y=-4[/tex]

sal recorded the outdoor temperature as -4°F at 7:30 am . at noon , it was 22°F . sal said the temperature changed by 18°F because 22-4=18. Is sal right or wrong .
Answer:
Sal is wrong, correct answer is 26°FStep-by-step explanation:
Initial temperature = -4°FTemperature at noon = 22°FTemperature change:
22 - (-4) = 22 + 4 = 26°FSal is wrong as the difference should be calculated as subtraction of the two values and absolute value of the result should be taken as the answer
Answer:
Sal was wrong as the change of temperature is 26°F
Step-by-step explanation:
recorded temperature at 7:30 A.M. = -4°F
at noon = 22°F
change of temperature = 22 - (-4) = 26°F
therefore, Sal was wrong as the change of temperature is 26°F
